[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0031] like Figure 1 As shown, an embodiment of the present invention provides a hotel room heating and cooling system, comprising: A regenerative buffer tank is used to receive energy medium discharged by the cooling and heating equipment in the hotel room and automatically discharge exhaust and waste; An energy storage tank is used to store heat energy or cold energy formed by the energy medium; An air energy heat pump is used to heat or cool the energy medium from the regenerative buffer tank and the energy storage tank; A delivery network is composed of multiple pipelines, electrically controlled valves, and circulating pumps, and is connected to the regenerative buffer tank, the energy storage tank, the air energy heat pump, and the cooling and heating equipment in the hotel room; A controller is connected to the air energy heat pump, the electrically controlled valves, the circulating pumps, and the load equipment, and is used to control the opening and closing of the air energy heat pump, the electrically controlled valves, the circulating pumps, and the cooling and heating equipment, which heats based on obtained heat energy and cools based on obtained cold energy; A temperature control panel compares the room temperature with the preset temperature to confirm the opening and closing of the cooling and heating equipment in the current room; An AI voice sound box helps users voice command the room temperature control panel to control the hotel room cooling and heating system through the AI voice sound box, preset the room comfortable temperature, and control the hotel room cooling and heating system operation; A personnel detection device detects the number of people in the room, and the system optimizes the cooling and heating strategy based on the number of people and the amount of personnel activity; A movement detection device detects the amount of personnel activity in the room, and the system optimizes the cooling and heating strategy based on the number of people and the amount of personnel activity; The regenerative buffer tank and the energy storage tank are provided with auxiliary heaters, and the controller is connected to the auxiliary heaters to control the operation of the auxiliary heaters in target scenarios.

[0032] The number of regenerative buffer tanks, energy storage tanks, and air energy heat pumps is not limited and can be multiple or only one. For example, Figure 2As shown, the hotel room cooling and heating system in the embodiment includes a regenerative buffer tank, three energy storage tanks, two air energy heat pumps, a multi-path delivery network, and a temperature control panel, an AI voice box, a personnel detection device, a movement detection device, and a group cooling and heating device installed in each area (i.e., each room). The group cooling and heating device includes a first device with cooling and heating functions, and a second device with heating function. The delivery network includes multiple electric control valves and two circulating pumps, including a first circulating pump connected to the energy storage tanks and the air energy heat pump for use when the air energy heat pump stores energy in the energy storage tanks, and a second circulating pump connected to the air energy heat pump and the regenerative buffer tank for use when the air energy heat pump heats or cools the energy medium, such as water, in the regenerative buffer tank, and then delivers it to the cooling and heating device. The energy medium in the embodiment is not limited to water, but can also include other media. The embodiment describes the use of water as the energy medium, but this does not limit the scope of the application.

[0033] To accelerate the warming of the energy medium in the regenerative buffer tank, enable the cooling and heating device to quickly warm the temperature in the hotel room, and enable the energy storage tank to have its own heat storage capacity, the regenerative buffer tank and the energy storage tank in the embodiment are each provided with an auxiliary heater connected to the controller for control by the controller.

[0034] Further, to accurately determine the temperature and liquid level of the energy medium in the regenerative buffer tank and the energy storage tank, and to achieve more accurate temperature control and energy medium replenishment, the regenerative buffer tank and the energy storage tank are each provided with a temperature detector and a liquid level detector connected to the controller to control the temperature and liquid level of the regenerative buffer tank and the energy storage tank based on the detected data, and to replenish the energy medium in a timely manner when the liquid level of the energy medium in the regenerative buffer tank and the energy storage tank is low.

[0035] The outer surface of the regenerative buffer tank and the energy storage tank in the embodiment is provided with a temperature switch connected to the corresponding auxiliary heater to disconnect the power supply circuit of the auxiliary heater and forcibly stop the operation of the auxiliary heater when the temperature of the energy medium in the regenerative buffer tank and the energy storage tank is too high, the controller fails to timely control the auxiliary heater to turn off, or the auxiliary heater fails to timely respond to the shutdown instruction.

[0036] For example, in the embodiment, the heating of the energy storage tank is protected by software and hardware mechanisms. The software protection mechanism is that the control system reads the temperature of the energy medium of the energy storage tank in real time. When the temperature of the energy medium is greater than or equal to the set protection temperature, the controller automatically controls to stop the heating of the energy storage tank, thereby realizing the software protection mechanism for the over-heating of the energy storage tank. The hardware protection mechanism is that a temperature control switch is added to the side of the energy storage tank. The temperature control switch is connected in series in the power supply circuit of the auxiliary heater of the energy storage tank. When the temperature control switch detects that the temperature of the outer surface of the energy storage tank is greater than or equal to the temperature at which the temperature control switch is turned off, the temperature control switch is automatically turned off, thereby cutting off the power supply of the auxiliary heater and stopping the heating of the energy storage tank, thereby realizing the hardware automatic protection mechanism for the over-heating of the energy storage tank. Similarly, the heating of the energy return buffer tank is also protected by software and hardware mechanisms. The software protection mechanism is that the control system reads the temperature of the energy medium of the energy return buffer tank in real time. When the temperature of the energy medium is greater than or equal to the set protection temperature, the control system automatically stops the heating of the energy return buffer tank, thereby realizing the software protection mechanism for the over-heating of the energy return buffer tank. The hardware protection mechanism is that a temperature control switch is added to the side of the energy return buffer tank. The temperature control switch is connected in series in the power supply circuit of the auxiliary heater of the energy return buffer tank. When the temperature control switch detects that the temperature of the outer surface of the energy return buffer tank is greater than or equal to the temperature at which the temperature control switch is turned off, the temperature control switch is automatically turned off, thereby cutting off the power supply of the auxiliary heater of the energy return buffer tank and stopping the heating of the energy return buffer tank.

[0037] Further, the hotel room cooling and heating system in the embodiment further comprises a photovoltaic power supply system and a dual-power intelligent switching device connected with the photovoltaic power supply system and commercial power. The dual-power intelligent switching device is connected with the energy return buffer tank, the energy storage tank, the air energy heat pump, the electric control valve, the circulating pump, the controller, the auxiliary heater, the temperature detector and the liquid level detector, so as to provide electric energy for them. The electric energy includes photovoltaic electricity and commercial power. The dual-power intelligent switching device preferentially uses photovoltaic electricity to supply energy. When the photovoltaic electricity cannot meet the power demand, part or all of the above-mentioned loads are switched to commercial power to supply energy.

[0038] As shown in Figure 3 Another embodiment of the present application simultaneously provides a cooling and heating energy storage and cooling and heating energy-saving method, which is applied to the hotel room cooling and heating system as described above. The method comprises the following steps: S1: obtaining the current temperature value in the hotel room and the use state. The use state includes the state that the room is unoccupied and multiple states according to the number of people in the room and the amount of activity of the people; S2: in the case that the current room temperature value meets the adjustment requirement, the energy buffer tank, the energy storage tank, the air energy heat pump, the transmission network and the cooling and heating device are controlled based on the first optimized cooling and heating strategy to limit the temperature of the corresponding room within a first range; S3: in the case that the current room temperature value meets the adjustment requirement, the energy buffer tank, the energy storage tank, the air energy heat pump, the transmission network and the cooling and heating device are controlled based on the corresponding different optimized cooling and heating strategy to limit the temperature of the corresponding room within a corresponding different range.

[0039] In the embodiment, one cooling and heating area, i.e. the above-mentioned area, is divided for each room of the hotel, each room, i.e. each cooling and heating area, comprises a temperature control panel, an AI voice sound box, a personnel detection device, a movement detection device and a cooling and heating device, the cooling and heating device comprises a first device with cooling and heating functions and a second device with heating functions. In the embodiment, each area comprises one temperature control panel, one AI voice sound box, one personnel detection device, one movement detection device, one fan coil with cooling and heating functions and one floor heating coil with heating functions, and of course, a plurality of groups can be included, which is not definite and can be determined according to the actual area size and the cooling and heating demand. The temperature control panel is provided with a temperature detection device for detecting the current area temperature and comparing it with the preset temperature to confirm the opening and closing of the cooling and heating device in the current room. For example, when the room is in a manual cooling mode, if the current area (i.e. room) temperature > the preset temperature + error value (which can be set and adjusted by the system), the temperature control panel controls the current cooling and heating device to be turned on, i.e. to provide cooling for the current room; and if the current area (i.e. room) temperature ≤ the preset temperature + error value, the temperature control panel controls the current cooling and heating device to be turned off, i.e. to stop providing cooling for the current room. For example, when the room is in a manual heating mode, if the current area (i.e. room) temperature < the preset temperature + error value (which can be set and adjusted by the system), the temperature control panel controls the current cooling and heating device to be turned on, i.e. to provide heating for the current room; and if the current area (i.e. room) temperature ≥ the preset temperature + error value, the temperature control panel controls the current cooling and heating device to be turned off, i.e. to stop providing heating for the current room; meanwhile, the temperature control panel uploads the related data such as the current control state, the current area (i.e. room) temperature and the preset temperature to the controller of the hotel room cooling and heating system, and then uploads the data to the cloud-based hotel room cooling and heating system, so that the controller or the cloud-based hotel room cooling and heating system determines how to control the supply of cooling energy and heating energy to the area based on the corresponding temperature and the current state.

[0040] The AI voice box helps the user to voice the command to control the room temperature control panel through the AI voice box, preset the room comfortable temperature and control the hotel room cooling and heating system operation: If the user directly says: "air conditioner on, temperature preset 25 degrees", if the current AI voice box communication docking is the cloud hotel room cooling and heating system, and the temperature control panel communication docking is the cloud hotel room cooling and heating system, at this time the AI voice box recognizes and uploads the instruction to the cloud hotel room cooling and heating system, and the cloud hotel room cooling and heating system further issues the instruction to the temperature control panel in the room. After receiving the instruction, the temperature control panel in the room controls the cooling and heating equipment to be turned on, and the room comfortable temperature is preset to 25 degrees. If the user directly says: "turn off the air conditioner, temperature preset 26 degrees", if the current AI voice box communication docking is the temperature control panel in the room, at this time the AI voice box recognizes and uploads the instruction to the temperature control panel in the room. After receiving the instruction, the temperature control panel in the room controls the cooling and heating equipment to be turned off, and the room comfortable temperature is preset to 26 degrees. The personnel detection device detects the number of people in the room through infrared temperature measurement and imaging technology, and the system optimizes the cooling and heating strategy based on the number of people and the activity amount of the people. The movement detection device detects the number of people moving in the room in real time through microwave real-time detection and comparison technology, and calculates the activity amount of the people. For example, if the number of object movements in the room is detected to be 0 times every 10 minutes (not limited to this value, which can be set and modified through the system according to actual use in the application), there is no activity amount; if the number of object movements is less than 10 times (not limited to this value, which can be set and modified through the system according to actual use in the application), there is a low activity amount; if the number of object movements is in the range of 11-100 times (not limited to this value, which can be set and modified through the system according to actual use in the application), there is a moderate activity amount; if the number of object movements is more than 100 times (not limited to this value, which can be set and modified through the system according to actual use in the application), there is a high activity amount; the system optimizes the cooling and heating strategy based on the number of people and the activity amount of the people. In this embodiment, when the system works in the intelligent cooling and heating mode, the state of each room in the hotel is divided into first to tenth states, but not limited to ten states, which can be divided into different states according to the application scenario.

[0044] In an embodiment, the method further comprises: S4: When the current photovoltaic energy is sufficient, or the current commercial power is in the low valley price period, if each air energy heat pump is in an idle state, start all air energy heat pumps, and turn on the electric control valve and the first circulating pump between the air energy heat pump and the energy storage tank in the delivery network, while controlling the remaining electric control valve and the second circulating pump to be closed, to successively store energy for each energy storage tank to be stored; S5: If part of the air energy heat pumps are in an idle state, and part of the air energy heat pumps are in a state of providing heat or cold energy for the cooling and heating equipment, start the air energy heat pump in the idle state, and turn on the electric control valve and the first circulating pump between the air energy heat pump in the idle state and the energy storage tank in the delivery network, to successively store energy for each energy storage tank to be stored using the air energy heat pump in the idle state; S6: Or start the air energy heat pump in the idle state, turn on the electromagnetic valve between the cooling and heating equipment and the air energy heat pump in the delivery network, so that all air energy heat pumps together provide heat or cold energy for the cooling and heating equipment, until the room temperature in the hotel room is in the corresponding range, the second circulating pump and the electric control valve between the energy storage tank to be stored and the air energy heat pump are closed, while the first circulating pump and the electric control valve between the air energy heat pump and the energy storage tank to be stored are turned on, to successively store energy for each energy storage tank to be stored.

[0045] For example, the system (controller) can implant the peak and valley electricity price schedule of the area where the hotel is located, and the system has a built-in calendar data / function. The system calculates the time period with the lowest peak and valley electricity price (low valley period) through the built-in calendar function, and sets the automatic start of the energy storage strategy in the low valley period. Specifically, the system can start the air energy heat pump to store energy in the energy storage tank 1, 2, 3 (such as Figure 2The energy medium in the storage tank is cooled or heated by the air energy heat pump. When the electricity price is higher than the lowest price in the valley period, the air energy heat pump stops cooling or heating the energy medium in the storage tank. At the same time, during the peak period, that is, the time period when the electricity price is the highest, the air energy heat pump is automatically stopped to provide energy, and cold energy or heat energy in the storage tanks 1, 2, and 3 is released to provide cold energy or heat energy for all areas. Specifically, the control strategies of the above-mentioned embodiments are as follows: When the electricity price is in the valley period, for example, the system reads that 1-5 o'clock every day is the valley period of the electricity price every day, that is, the time period when the electricity price is the lowest in a day, the system can start to cool or heat the energy medium in the storage tanks 1, 2, and 3 by the air energy heat pump at 1 o'clock every day. Or when the photovoltaic energy is sufficient, the system can start to enter the energy storage stage, and cool or heat the energy medium in the storage tanks 1, 2, and 3 by the air energy heat pump to realize cold energy storage and heat energy storage. Before entering the energy storage stage, the outdoor temperature and the indoor temperature need to be distinguished, and based on the distinguished results, it is determined to start one air energy heat pump to store energy, and the other air energy heat pump to provide cooling or heating for all areas (temperature-unqualified areas), and when the cooling or heating for all areas is satisfied, the two air energy heat pumps enter the energy storage mode together to store energy for the storage tanks; or it is determined that the two air energy heat pumps provide cooling or heating for all areas together, and when the cooling or heating for all areas is satisfied, they enter the energy storage mode together. The discrimination conditions are as follows: When cooling energy storage is performed, if the outdoor temperature value is greater than the double-air-energy-heat-pump cooling mode temperature threshold set by the user, or when heat energy storage is performed, if the outdoor temperature value is less than the double-air-energy-heat-pump heating mode temperature threshold set by the user, the system determines to start the two air energy heat pumps to provide cooling or heating for all areas together, and when the cooling or heating for all areas is satisfied, the two air energy heat pumps enter the energy storage mode together; otherwise, when cooling energy storage is performed, if the outdoor temperature value is less than the double-air-energy-heat-pump cooling mode temperature threshold set by the user, or when heat energy storage is performed, if the outdoor temperature value is greater than the double-air-energy-heat-pump heating mode temperature threshold set by the user, then one air energy heat pump is started to store energy, and the other air energy heat pump provides cooling or heating for all areas, and when the cooling or heating for all areas is satisfied, the two air energy heat pumps enter the energy storage mode together. When the two air energy heat pumps (that is, the two air energy heat pumps in the double-air-energy-heat-pump system) are started to provide cooling or heating for all areas, until the cooling or heating for all areas is satisfied, that is, the temperatures of all areas meet the requirements, the two air energy heat pumps enter the energy storage mode together, and the control method specifically includes the following steps: Figure 2 When the two air energy heat pumps provide cooling or heating for all areas together, as shown in FIG. 1, the system can start to cool or heat the energy medium in the storage tanks 1, 2, and 3 by the air energy heat pump, and when the cooling or heating for all areas is satisfied, the two air energy heat pumps enter the energy storage mode together. The control method specifically includes the following steps: Figure 2 ​As shown, air source heat pumps 1 and 2 start working, and electrically controlled valves 1, 28, 2, 27, 3, 26, 25, and 4 are closed, while all other electrically controlled valves are open. Circulation pump 1 stops working, and circulation pump 2 starts working, with both air source heat pumps working together to provide cooling or heating to all areas. When the cooling or heating needs of a corresponding area are met, the corresponding electrically controlled valve closes; for example, for area 1, electrically controlled valves 9, 10, 19, and 20 are closed. When the cooling or heating needs of all areas are met, electrically controlled valve 8 closes, circulation pump 1 starts working, circulation pump 2 stops working, and electrically controlled valves 1 and 28 open. The dual air source heat pumps begin cooling or heating the energy medium inside storage tank 1. When the temperature detection device inside storage tank 1 detects that the internal energy medium temperature equals the user-set storage temperature (this value can be set and modified through the system user software), the electric control valve 1 closes first. Simultaneously, when the liquid level detection device inside storage tank 1 detects that the internal liquid level equals the user-set storage liquid level, the electric control valve 28 closes, and the dual air source heat pumps stop cooling or heating the energy medium inside storage tank 1. Then, the electric control valves 2 and 27 open simultaneously, and the dual air source heat pumps begin cooling or heating the energy medium inside storage tank 2. When the temperature detection device inside storage tank 2 detects that the internal energy medium temperature equals the user-set storage temperature (this value can be set and modified through the system user software), the electric control valve 2 closes first. Simultaneously, when the liquid level detection device inside storage tank 2 detects that the internal liquid level equals the user-set storage liquid level (this value can be set and modified through the system user software), the electric control valve 27 closes then. At this point, the dual air source heat pumps stop cooling or heating the energy medium inside storage tank 2, and simultaneously open the electronic control valves 3 and 26, allowing the dual air source heat pumps to begin cooling or heating the energy medium inside storage tank 3. When the temperature detection device inside storage tank 3 detects that the internal energy medium temperature equals the user-set storage temperature (this value can be set and modified through the system user software), electronic control valve 3 is closed first. Simultaneously, when the liquid level detection device inside storage tank 3 detects that the internal liquid level equals the user-set storage liquid level (this value can be set and modified through the system user software), electronic control valve 26 is closed. At this point, the dual air source heat pumps stop cooling or heating the energy medium inside storage tank 3, completing one energy storage cycle. When the corresponding area requires cooling or heating again during energy storage, the system prioritizes switching to provide cooling or heating to that area. Once the cooling or heating needs of all areas are met again, the system switches back to energy storage mode, and this cycle repeats. When switching from energy storage mode to cooling or heating mode, the solenoid valve 4 is closed and the solenoid valve 8 is opened; circulation pump 1 stops working and circulation pump 2 starts working.If the current photovoltaic energy is not sufficient, or if it is determined that the current time is not in the time period of 1-5 o'clock, then the energy storage mode is not entered, and if the energy storage mode is entered, then the energy storage mode is automatically exited.

[0046] When the air energy heat pump 1 stores energy, the air energy heat pump 2 provides cooling or heating mode for all areas, first close the electric control valve 6, 23, separate the two air energy heat pump working area; Then close the electric control valve 2, 27, 3, 26, 25, let the air energy heat pump 1 first only for energy storage tank 1 energy storage, other electric control valve is opened. Circulating pump 2, air energy heat pump 2 start working, to provide cooling or heating for all areas. Circulating pump 1, air energy heat pump 1 start working, begin to refrigeration or heating of energy medium inside the energy storage tank 1, when the temperature detection device inside the energy storage tank 1 detects the internal energy medium temperature value = user set energy storage temperature value (this value can be set through the system user software and modified adjustment), first close the electric control valve 1, at the same time through the liquid level detection device inside the energy storage tank 1 detects the internal liquid level value = user set energy storage liquid level value, then close the electric control valve 28, at this time, the air energy heat pump 1 stops refrigeration or heating of energy medium inside the energy storage tank 1. After that, open the electric control valve 2, 27 at the same time, the air energy heat pump 1 begins to refrigeration or heating of energy medium inside the energy storage tank 2, when the temperature detection device inside the energy storage tank 2 detects the internal energy medium temperature value = user set energy storage temperature value (this value can be set through the system user software and modified adjustment), first close the electric control valve 2, at the same time through the liquid level detection device inside the energy storage tank 2 detects the internal liquid level value = user set energy storage liquid level value, then close the electric control valve 27, at this time, the air energy heat pump 1 stops refrigeration or heating of energy medium inside the energy storage tank 2. After that, open the electric control valve 3, 26 at the same time, the air energy heat pump 1 begins to refrigeration or heating of energy medium inside the energy storage tank 3. When the temperature detection device inside the energy storage tank 3 detects the internal energy medium temperature value = user set energy storage temperature value, first close the electric control valve 3, at the same time through the liquid level detection device inside the energy storage tank 3 detects the internal liquid level value = user set energy storage liquid level value, then close the electric control valve 26, at this time, the air energy heat pump 1 stops refrigeration or heating of energy medium inside the energy storage tank 3, through the above process to complete all the energy storage tank energy storage cycle. When the photovoltaic power supply energy is sufficient, or the current mains is in the low valley price period of the peak valley price in the region, if the air energy heat pump 1 is in energy storage, when the air energy heat pump 2 meets the cooling or heating demand of all areas, it automatically switches to energy storage mode and stores energy with the air energy heat pump 1. When the corresponding area needs cooling again, the air energy heat pump 2 switches to provide cooling or heating for the corresponding area again, when it meets the cooling or heating demand of all areas again, it switches to energy storage mode again. When the air energy heat pump 2 switches from energy storage mode to cooling or heating mode, close the electric control valve 6, 23, open the electric control valve 8, start circulating pump 2, at the same time, the cooling or heating area electric control valve is opened; When the air energy heat pump 2 switches from cooling or heating mode to energy storage mode, close the electric control valve 8, open the electric control valve 6, 23, stop circulating pump 2, at the same time, all the cooling or heating area electric control valve is closed.If the current photovoltaic power is not sufficient, or the current time is not in the 1-5 time period, that is, not in the low valley time period, the air energy heat pump 1, 2 does not enter the energy storage mode, and if in the energy storage mode, it automatically exits the energy storage mode.

[0047] In another embodiment, the method further comprises: S7: When the current photovoltaic power is sufficient, or the city power is in the low valley time period, start the auxiliary heater in the energy storage tank to be stored to heat the energy storage tank to be stored, so that the energy storage tank stores heat energy; S8: When the energy medium temperature in the energy storage tank reaches the target value, control the auxiliary heater to stop heating.

[0048] For example, in the embodiment, in the case of determining that the current is photovoltaic power supply and the power is sufficient, the energy storage strategy can be automatically started, or in the case of insufficient photovoltaic power supply energy, but the current time is in the low valley time period, the system will also automatically start the energy storage strategy. The energy storage strategy is to control the three energy storage tanks to start the auxiliary heater of each energy storage tank to heat the energy medium in the energy storage tank for energy storage. In the case of insufficient photovoltaic power supply energy and the current time exceeding the low valley period, or in the case of city power energy storage but the current time exceeding the low valley period, the auxiliary heater is controlled to stop heating the energy medium in the energy storage tank for energy storage. When the system determines that the current is city power supply and the peak time period of the peak valley price of the region, the heat energy in the energy storage tanks 1, 2 and 3 is released to supply heat to the region requiring energy supply, and the control strategy specifically includes: When the energy storage tank is to be stored, it is determined whether the current photovoltaic power is sufficient and can be used for energy storage. If so, the photovoltaic power is used for energy storage. If the photovoltaic power is not sufficient, but the current time is between 1 and 5, which is in the low valley time period, the city power can be used for energy storage. In the embodiment, the switching of the power supply is realized by using the dual power intelligent switching device in the system. The energy storage strategy in the embodiment can start the auxiliary heater of the three energy storage tanks to heat the energy medium in the energy storage tank for energy storage. When the temperature detection device in the energy storage tank detects that the internal energy medium temperature value is equal to the user-set energy storage temperature value (which can be set, modified and adjusted through the system user software), or the time exceeds the 1-5 time period, and the photovoltaic power supply energy is insufficient, the auxiliary heater of the corresponding energy storage tank is controlled to stop heating.

[0049] That is, in order to further save energy in the embodiment, a photovoltaic power supply system and a dual power intelligent switching device are arranged. When storing energy in the energy storage tank, it is determined whether the photovoltaic power supply system can perform power supply, if yes, the photovoltaic power supply system is used to supply power, and when the photovoltaic power supply system cannot meet the power supply demand, it is determined whether it is in the low valley electricity price period, if yes, the mains power supply is switched to realize the energy storage of the energy storage tank. In addition, in the non-low valley electricity price period, the power required for the hotel room cooling and heating system to run is also supplied by the photovoltaic power supply system, which can flexibly adjust the connected load according to the size of the electric energy, such as only supplying power to the air energy heat pump, or only supplying power to the transmission network, the cooling and heating equipment, etc., or simultaneously supplying power to the air energy heat pump, the cooling and heating equipment, etc., or supplying power to the entire cooling and heating system, etc., and the specific method is not unique. For the electric device that cannot be powered by the photovoltaic power supply system, the mains power supply is used.

[0050] Further, the first to tenth optimization cooling and heating strategies in the embodiment include determining the energy storage tank capable of supplying cold energy or heat energy in combination with the temperature of the energy storage tank and the temperature regulation demand in the peak electricity price period of the mains power supply and the peak valley electricity price of the region, and preferentially using the determined energy storage tank to supply cold energy or heat energy to the cooling and heating equipment. When the determined energy storage tank is multiple, each energy storage tank is used to supply cold energy or heat energy to the cooling and heating equipment one by one, and each energy storage tank is controlled to stop supplying energy medium when the energy medium temperature thereof does not match the temperature regulation demand.

[0051] For example, if the system reads that 9:00-12:00 every day is the peak electricity price period every day, when the system determines 9:00 every day, first, the working mode of the air energy heat pump is judged, if it is the cooling mode, then the energy medium temperature of each energy storage tank is judged, when the energy medium temperature value detected by the temperature detection device in the energy storage tank is < (the user-set stop cooling energy temperature value - the error value), the corresponding energy storage tank can release cold energy to supply cold to all areas, otherwise it does not release; if it is the heating mode, then the energy medium temperature of each energy storage tank is judged, when the energy medium temperature value detected by the temperature detection device in the energy storage tank is > (the user-set stop heating energy temperature value + the error value), the corresponding energy storage tank can release heat energy to supply heat to all areas, otherwise it does not release. If the current state of all energy storage tanks does not allow the release of cold energy or heat energy, the air energy heat pump is allowed to provide cold energy or heat energy to supply cold or heat to all areas, if subsequent determination determines that there is an energy storage tank allowing the release of cold energy or heat energy, the air energy heat pump is stopped and the corresponding energy storage tank is started to release cold energy or heat energy to supply heat or cold to all areas, and the control method specifically includes: For example, Figure 2As shown, the air energy heat pump 1, 2 stops working, the electric control valve 5, 7, 24, 22 is closed, the circulating pump 1 stops working, and the circulating pump 2 starts working. At this time, the energy stored in the energy storage tank 1 is used for cooling or heating first, the electric control valve 1, 28, 4, 6, 8, 23, 25 and the electric control valve of the heating or cooling area are opened, the system starts to provide heating or cooling for all areas by the heat energy or cold energy stored in the energy storage tank 1, and the electric control valve 2, 27, 3, 26 of the energy storage tank 2, 3 is closed. After the heat energy in the energy storage tank 1 is completely released, it is gradually replaced. For example, when the temperature detection device in the energy storage tank 1 detects that the energy medium temperature value = the user set stop heating or cooling temperature value, the electric control valve 1 is closed first, and the energy storage tank 1 stops heating or cooling. At the same time, when the liquid level detection device in the energy storage tank detects that the liquid level value = the user set energy storage liquid level value, the electric control valve 28 is closed. Then the energy storage tank 2 starts to replace the energy storage tank 1 to provide heating or cooling for all areas, and the electric control valve 2, 27 is opened. When the temperature detection device in the energy storage tank 2 detects that the energy medium temperature value = the user set stop heating or cooling temperature value, the electric control valve 2 is closed first, and the energy storage tank 2 stops heating or cooling. At the same time, when the liquid level detection device in the energy storage tank detects that the liquid level value = the user set energy storage liquid level value, the electric control valve 27 is closed. The energy storage tank 3 starts to replace the energy storage tank 2 to provide heating or cooling for all areas, and the electric control valve 3, 26 is opened. When the temperature detection device in the energy storage tank 3 detects that the energy medium temperature value = the user set stop heating or cooling temperature value, the electric control valve 3 is closed first, and the energy storage tank 3 stops heating or cooling. At the same time, when the liquid level detection device in the energy storage tank detects that the liquid level value = the user set energy storage liquid level value, the electric control valve 26 is closed. At this time, the system automatically switches to heating or cooling for all areas by the air energy heat pump, the electric control valve 4, 25 is closed, and the electric control valve 5, 24, 7, 22 is opened, so as to complete the cycle of releasing heat energy or cold energy in the energy storage tank to provide heating or cooling for all areas, and then release it again after the next energy storage is completed, and enter the next release cycle, so as to circulate.

[0052] In another embodiment, the first to tenth optimization cooling and heating strategies further comprise detecting whether the temperature in the hotel room meets the requirements or detecting whether the change amount of the temperature in the hotel room in a second period meets the requirements after the energy storage tank provides heat energy or cold energy for a first period. If not, one or more air energy heat pumps are controlled to start, and the corresponding pipeline in the delivery network is controlled to be turned on, so that the energy medium in the energy buffer tank is input into the cooling and heating equipment after being heated or cooled by the air energy heat pump.

[0053] For example, when the heat or cold energy is released by one or more energy storage tanks to heat or cool all areas, the system will detect the temperature increase or decrease data of the heating or cooling area in real time, and when the temperature of the heating or cooling area does not reach the expected value within a certain time, such as 10 (this value can be set and modified by the system user software) minutes of heating area temperature increase of less than 2 (this value can be set and modified by the system user software) degrees, or 10 (this value can be set and modified by the system user software) minutes of cooling area temperature decrease of less than 2 (this value can be set and modified by the system user software) degrees, the system will automatically start the air energy heat pump 2 to assist in heating or cooling all areas. When the air energy heat pump 2 assists in heating or cooling all areas, only the air energy heat pump 2 needs to be started, and the electric control valves 7, 22 are opened. If the air energy heat pump 2 assists in heating for 10 (this value can be set and modified by the system user software) minutes, and the heating area temperature still increases by less than 2 (this value can be set and modified by the system user software) degrees, or if the air energy heat pump 2 assists in cooling for 10 (this value can be set and modified by the system user software) minutes, and the cooling area temperature still decreases by less than 2 (this value can be set and modified by the system user software) degrees, the system will automatically start the double air energy heat pump to assist in heating or cooling all areas. When the double air energy heat pump assists in heating or cooling all areas, only the air energy heat pumps 1, 2 need to be started, and the electric control valves 7, 22, 5, 24 are opened.

[0054] In another embodiment, the cooling and heating device includes a first device with cooling and heating functions, and a second device with heating functions, and each area in the hotel room is provided with the first device and the second device. As described above, the first device can be but is not limited to a fan coil, and the second device is a floor heating coil.

[0055] The first optimized cooling and heating strategy is used to control the energy buffer tank, energy storage tank, air energy heat pump, delivery network, and cooling and heating device, so that the temperature of the corresponding area is limited to a first range, which includes: S12: When the temperature of the area in the first state needs to be increased to the corresponding specified temperature, the energy buffer tank, air energy heat pump, and the second circulating pump in the delivery network are controlled to open the electric control valve for connecting the energy buffer tank, air energy heat pump, and the second device in the corresponding area, and the remaining devices are closed, so that the air energy heat pump supplies heat energy to the second device until the temperature of the area reaches the specified temperature. S13: When the temperature of the area in the first state needs to be reduced to the corresponding specified temperature, the control of the regenerative buffer tank, air energy heat pump, and the second circulating pump in the delivery network, the electric control valve for opening the first device inter-pipeline in the corresponding area is opened, and the remaining devices are closed, so that the air energy heat pump supplies cold energy to the first device until the temperature of the area reaches the specified temperature.

[0056] For example, in the heating season, when the system detects that each heating area (i.e. room) is unoccupied, the system automatically starts the low-power energy-saving heating mode (maintain a certain room temperature, prevent the delivery network from freezing, etc.), that is, a heating mode in which an air energy heat pump provides heat energy for the floor heating coil. The control method is as follows: The air energy heat pump 1 stops working, the air energy heat pump 2 starts working; the circulating pump 1 stops working, the circulating pump 2 starts working; the fan coil 1, 2...N stops working, the corresponding electric control valves 10, 19, 12, 17, 14, 15 and 1, 28, 2, 27, 3, 26, 25, 4, 5, 24, 6, 23 are closed, and the electric control valves 7, 22, 8, 9, 20, 11, 18, 13, 16 are opened. The system delivers heat energy to the floor heating coil 1, 2...N through the air energy heat pump 2, that is, provides low-power heating for the areas 1, 2...N. At the same time, the system detects the temperature of each area in real time. If the preset temperature is not less than 5 (this value can be set, modified and adjusted through the system user software) degrees, the heating for this area is stopped, that is, the corresponding electric control valves are closed. If area 1 is unoccupied and the temperature is not less than 5 degrees, the corresponding electric control valves 9, 20 are closed to stop heating for this area. When the temperature of this area is less than 5 degrees, the corresponding electric control valves 9, 20 are opened again to restore heating for this area. In this way, the temperature in the area is maintained at 5 degrees when unoccupied. The principle is the same for other areas. When the temperature of all areas reaches the corresponding demand, the air energy heat pump 2 stops working, and the circulating pump 2 stops working, that is, the system stops heating. When the temperature of one area does not reach the demand, the air energy heat pump 2 starts working, and the circulating pump 2 starts working, and the system enters the low-power energy-saving cooling mode again, so as to realize the optimal energy-saving effect while maintaining the temperature to meet the demand.

[0057] In the cooling season, when the system detects that each cooling area is unoccupied, the system automatically starts the low-power energy-saving cooling mode (which can also be set to turn off the cooling and heating devices, that is, not to provide cooling and heating when the room is unoccupied), that is, a cooling mode in which an air energy heat pump provides cold energy for the fan coil. The control method is as follows: All the floor heating coils stop working, i.e. the corresponding electric control valves, i.e. the electric control valves 9, 20, 11, 18, 13, 16 and 1, 28, 2, 27, 3, 26, 25, 4, 5, 24, 6, 23, are closed, the air energy heat pump 1 stops working, and the air energy heat pump 2 starts working in refrigeration; the circulating pump 1 stops working, and the circulating pump 2 starts working; the fan coil 1, 2...N starts working, and the corresponding electric control valves 10, 19, 12, 17, 14, 15 and 7, 22, 8, are opened, and the system supplies cold energy to the fan coil 1, 2, N through the air energy heat pump 2, i.e. provides low-power cooling for the region 1, 2...N. At the same time, the system detects the temperature of each region in real time, and when the preset temperature is not greater than 30 (this value can be set and modified by the system user software) degrees when there is no one, the cooling to this region is stopped, i.e. the corresponding fan coil and electric control valve are closed. For example, when there is no one in the region 1, and the temperature is not greater than 30 degrees, the corresponding fan coil 1 and electric control valves 10, 19 are closed, and the cooling to this region is stopped; when the temperature of this region is greater than 30 degrees, the corresponding fan coil 1 and electric control valves 10, 19 are opened again, and the cooling to this region is restored. In this way, the temperature in the region is kept at 30 degrees or below when there is no one, and the principle is the same for other regions. When the temperature of all regions reaches the demand, the air energy heat pump 2 stops working, and the circulating pump 2 stops working, i.e. the system stops cooling. When the temperature of one region does not reach the demand, the air energy heat pump 2 starts working in refrigeration, and the circulating pump 2 starts working, and the system enters the low-power energy-saving cooling mode again, so as to realize the optimal energy-saving effect while keeping the temperature meeting the demand.

[0058] The second to tenth optimization cooling and heating strategies control the energy buffer tank, energy storage tank, air energy heat pump, delivery network, and cooling and heating equipment to limit the temperature of the corresponding region within the second to tenth range, including: S14: When the temperature of the region in the second to tenth state needs to be quickly raised to the corresponding specified temperature, determine the first energy storage tank that can supply heat energy according to the temperature of the energy medium in each energy storage tank, control the energy buffer tank, all air energy heat pumps, the first energy storage tank, the auxiliary heater in the energy buffer tank, the second circulating pump in the delivery network, and the electric control valve for opening the pipeline between the first equipment, the second equipment in the energy buffer tank, the air energy heat pump, the first energy storage tank, and the corresponding region, and close the first circulating pump, so that the air energy heat pump, the energy buffer tank, and the first energy storage tank supply heat energy to the first equipment and the second equipment, until the temperature of the region quickly reaches the specified temperature. S15: When the temperature of the area in the second to tenth state needs to be quickly reduced to the corresponding specified temperature, the second energy storage tank that can supply cold energy is determined according to the temperature of the energy medium in each energy storage tank, the energy return buffer tank, all air energy heat pumps, the second energy storage tank, and the second circulating pump in the conveying network for the first equipment in the area are controlled to be opened, and the rest of the devices are closed, so that the air energy heat pump and the second energy storage tank supply cold energy to the first equipment until the temperature of the area quickly reaches the specified temperature.

[0059] For example, when the system needs to quickly start the high-temperature quick heating mode according to the cooling and heating area state, that is, the double air energy heat pump is started, the energy return buffer tank auxiliary heater is started, and the energy storage tanks 1, 2, and 3 simultaneously provide heat energy for the fan coil and the floor heating coil of all areas in the heating mode. As shown in FIG. 8, the control method is as follows: Figure 4 ​The circulating pump 1 stops working, and the circulating pump 1 is started only when the air energy heat pump stores energy for the energy storage tank, that is, when the system does not store energy for the energy storage tank through the air energy heat pump, the circulating pump 1 stops working. The circulating pump 2 starts working, and the air energy heat pumps 1 and 2 start heating, and the energy buffer tank starts auxiliary heating. The corresponding electric control valves 1, 28, 2, 27, 3, 26, 25, 4, 5, 24, 6, 23, 7, 22, 8 are opened, and the energy storage tanks 1, 2 and 3 release heat energy at the same time. When the system detects that the temperature value of the energy medium in the corresponding energy storage tank is ≤ the user-set stop heating temperature value through the temperature detection device in the system, the energy storage tank stops releasing heat energy, and the corresponding electric control valve is closed. At the same time, according to the application scene, the auxiliary heater in the energy storage tank can be selected to be started, until the temperature value of the energy medium in the corresponding energy storage tank > the user-set stop heating temperature value, the auxiliary heater is controlled to be closed, and the corresponding electric control valve is opened, and the heat energy of the energy storage tank is released again. In the high-temperature acceleration heating mode, the system will detect the temperature demand of the cold and warm area in real time, and when the temperature of the cold and warm area reaches the demand, the heating of the area is stopped, that is, the corresponding electric control valve is closed. When the temperature demand of the area 1 is not less than 18 (this value can be set and modified by the user software of the system) degrees, the corresponding electric control valves 9, 20, 10 and 19 are closed, and the heating of the area is stopped; when the temperature of the area is less than 18 degrees, the corresponding electric control valves 9, 20, 10 and 19 are opened again, and the heating of the area is restored. In this way, the temperature of the area 1 is kept at 18 degrees or above. When the system detects that all the cold and warm areas are in the first state, the system automatically enters the low-power energy-saving heating mode, that is, the energy buffer tank auxiliary heating stops, the energy storage tanks 1, 2 and 3 stop releasing heat energy, the air energy heat pump 1 stops working, and the air energy heat pump 2 starts working. The fan coil 1, 2...N stops working, and the corresponding electric control valves 10, 19, 12, 17, 14, 15 and 1, 28, 2, 27, 3, 26, 25, 4, 5, 24, 6, 23 are closed, and the electric control valves 7, 22, 8, 9, 20, 11, 18, 13, 16 are opened. When the system detects that the temperature of all areas reaches the demand, the air energy heat pump 2 stops working, and the circulating pump 2 stops working, at which time the system stops heating. When the system detects that the temperature of a certain area does not reach the demand, the air energy heat pump 2 starts heating, and the circulating pump 2 starts working, and the system automatically enters the low-power energy-saving heating mode. When the system detects the state of the cold and warm area and needs to quickly start the high-temperature rapid heating mode, the system enters the high-temperature rapid heating mode again. In this way, the optimal energy-saving effect is achieved.

[0060] When the system detects that the cold and warm area needs to quickly start the low-temperature rapid cooling mode, the system quickly starts the low-temperature rapid cooling mode, that is, the double air energy heat pumps start cooling, the energy storage tanks 1, 2 and 3 release cold energy, and the corresponding areas of the fan coil provide cold energy. The control method is as follows: The energy storage tanks 1, 2, 3 first pass through the temperature detection device in it, detect the energy medium temperature value in the energy storage tank, such as the energy medium temperature value in the energy storage tank < user set stop cooling temperature value, open the corresponding electric control valve to release cold energy. For example, when the energy medium temperature value in the energy storage tank 1 < the user set stop cooling temperature value, open the electric control valve 1, 28; when the energy medium temperature value in the energy storage tanks 1, 2 < the user set stop cooling temperature value, open the electric control valve 1, 28, 2, 27; when the energy medium temperature value in the energy storage tanks 1, 2, 3 < the user set stop cooling temperature value, open the electric control valve 1, 28, 2, 27, 3, 26. At the same time, the circulating pump 2 starts to work, and the circulating pump 1 stops working (the circulating pump 1 only works when the air energy heat pump stores energy for the energy storage tank, that is, when the system does not store energy for the energy storage tank through the air energy heat pump, the circulating pump 1 stops working), the air energy heat pump 1, 2 starts to cool, and the corresponding electric control valve 25, 4, 24, 5, 6, 7, 22, 8 is opened. That is, the system simultaneously through double air energy heat pump, energy storage tank 1, 2, 3 for according to the cooling and heating area state, quickly start the low temperature fast cooling area fan coil to transport cold energy mode, that is, the low temperature fast cooling mode. During cooling, the system detects the cooling and heating area temperature in real time, and when the cooling and heating area temperature reaches the demand, the cooling of the area is stopped, that is, the corresponding electric control valve is closed. For example, when the temperature of region 1 is not greater than 26 (this value can be set and modified by the system user software) degrees, the corresponding electric control valve 19, 10 is closed, and the cooling of the region is stopped; when the temperature of the region 1 is greater than 26 degrees, the corresponding electric control valve 19, 10 is opened again, and the cooling of the region is restored. In this way, the temperature of region 1 is kept at 26 degrees or below. When the system detects that a certain region is in the first state in real time, the region needs to enter the low-power energy-saving cooling mode (or the cooling can be turned off), that is, the temperature of the region is kept at 30 (this value can be set and modified by the system user software) degrees, and the principle of other regions is the same. When all cooling and heating areas are in the first state, the system automatically enters the low-power energy-saving cooling mode, that is, the energy storage tank 1, 2, 3 stops releasing cold energy, and the corresponding electric control valve 1, 28, 2, 27, 3, 26 is closed; the air energy heat pump 1 stops cooling, and the corresponding electric control valve 5, 24 is closed; the air energy heat pump 2 starts to work to provide cooling for the cooling and heating area that does not reach the temperature demand. When the system detects that the temperature of all regions reaches the temperature demand, that is, the temperature of all regions is not greater than 30 degrees, the air energy heat pump 2 stops working, and the circulating pump 2 stops working, that is, the system stops cooling. When the system detects that the temperature demand of a certain cooling and heating region is not reached, the air energy heat pump 2 starts to cool, and the circulating pump 2 starts to work, that is, the system automatically enters the low-power energy-saving cooling mode. In this way, the optimal energy-saving effect is realized.

[0061] Further, if the hotel is in a cold area, the heating efficiency is poor, the method further comprises: S16: when the temperature rise of the region in a set period meets the auxiliary heating requirement, the first device, the air energy heat pump in the idle state and the electric control valve in the conveying network for conducting the pipeline between the air energy heat pump and the first device and the second device are started; S17: when the temperature rise of the region in a set period meets the auxiliary heating requirement, the auxiliary heater in the energy buffer tank is started; S18: when the temperature rise of the region in a set period meets the auxiliary heating requirement, the third energy storage tank that can supply heat energy is determined according to the temperature of the energy medium in each energy storage tank, the third energy storage tank and the electric control valve in the conveying network for conducting the pipeline between the third energy storage tank and the first device and the second device are started.

[0062] For example, in the temperature rise stage, if it is found that the temperature rise of the heating region does not meet the requirement after heating for a period of time, the fan coil is started to make the fan coil and the floor heating coil supply heat at the same time to accelerate the temperature rise. Or the air energy heat pump currently in the idle state is started to supply energy to the first device and the second device corresponding to the region. Then the region temperature is continuously monitored, if it is found that the temperature rise effect still does not meet the requirement, the heating auxiliary device in the energy buffer tank is started to heat the energy medium in the energy buffer tank to further assist the region temperature rise. The region temperature is continuously monitored, if it is found that the temperature rise effect still does not meet the requirement, the energy storage tank that can currently be used to supply heat energy is determined, and the energy storage tank is started to conduct the corresponding electric control valve to supply energy to the first device and the second device corresponding to the region, so as to realize auxiliary heating of the region temperature to meet the requirement. That is, in this embodiment, the devices used for auxiliary heating are gradually increased by monitoring the region temperature rise effect, and the required temperature rise effect is finally realized.

[0063] In actual application, that is, in the heating process not limited to the above embodiment, the auxiliary heating of the energy buffer tank and the auxiliary heating of the energy storage tank can be controlled by the following strategies: The system reads the temperature of the energy medium in the energy buffer tank through the temperature detection device in the energy buffer tank, and then combines the indoor temperature, the user demand temperature and the system running time to make logical judgment, so as to determine whether the heating component in the energy buffer tank needs to assist heating. When assistance is needed, the energy medium in the energy buffer tank can be quickly heated to reduce the heat loss of the energy medium, so as to achieve further energy saving effect; at the same time, when the system starts the energy buffer tank auxiliary heating, the system also reads the temperature of the energy medium in the energy buffer tank through the temperature detection device of the energy buffer tank, and then combines the indoor temperature and the user demand temperature to make logical judgment, so as to determine whether the auxiliary heater in the energy buffer tank needs to stop auxiliary heating. The start-stop strategy of the energy buffer tank auxiliary heating includes: The start-stop strategy of the energy buffer tank auxiliary heating includes: Air energy heat pump total time of single operation ≥ user set total time of operation, and indoor temperature < user set indoor temperature requirement + error value, both conditions are met at the same time, start the auxiliary heater of the energy return buffer tank.

[0064] Air energy heat pump total time of single operation: that is, the total time of single power operation of the air energy heat pump; User set total time of operation: the time set by the user through the system user software; Indoor temperature: the indoor temperature of the area requiring heating; Error value: the value set by the user through the system user software, by setting this value, the auxiliary heating function can be prevented from being mistakenly started; This strategy is convenient for the hotel room to have no heating for a long time, the indoor temperature is low, and the user requires the indoor temperature to be quickly raised. When the hotel raises the temperature in the second to tenth state, the auxiliary heating and air energy heat pump are superimposed to quickly raise the indoor temperature of the user.

[0065] Energy return buffer tank auxiliary heating stop strategy 1: Energy return buffer tank auxiliary heating stop strategy 1:

[0066] Energy return buffer tank auxiliary heating stop strategy 1: User set energy return buffer tank stop heating temperature: the user sets and modifies the adjustment through the system user software, this value is mainly to protect the energy return buffer tank from being damaged due to the high temperature of the energy medium in the energy return buffer tank or the related accessories inside the energy return buffer tank, so when the temperature of the energy medium in the energy return buffer tank reaches the set temperature, the auxiliary heating function of the energy return buffer tank is stopped.

[0067] Energy return buffer tank auxiliary heating start strategy 2: Energy return buffer tank auxiliary heating start strategy 2:

[0068] Energy return buffer tank auxiliary heating start strategy 2: User set energy return buffer tank start heating temperature: the user sets and modifies the adjustment through the system user software, when the temperature of the current energy medium in the energy return buffer tank is too low, it indicates that the current air energy heat pump heating effect is not as expected, which is generally caused by the current outdoor temperature being too low.

[0069] The strategy facilitates automatic starting of the regenerative buffer tank auxiliary heating function when the outdoor temperature is too low to cause the air energy heat pump heating effect to be less than expected and to reach the user's temperature requirement, which can stack the air energy heat pump heating to quickly raise the indoor temperature.

[0070] Regenerative buffer tank auxiliary heating stop strategy 2: The regenerative buffer tank energy medium temperature is greater than or equal to the user-set regenerative buffer tank stop heating temperature, or the indoor temperature is greater than or equal to the user-set indoor temperature requirement minus 2 (this value can be set and modified by the system user software), and when either of the two conditions is met, the system will turn off the regenerative buffer tank auxiliary heater.

[0071] In addition, the regenerative buffer tank in the embodiment is also connected with a supplementary energy medium pipeline to realize the automatic supplementary energy medium function in combination with the liquid level detection device. The air energy heat pump will be affected by the lack of energy medium, which will increase the air energy heat pump working time and thus increase the power consumption. The system can read the liquid level of the regenerative buffer tank through the regenerative buffer tank liquid level detection device in real time, and when the system detects that the liquid level is lower than the set supplementary liquid level, the system controls the electric control valve in the energy medium supplementary pipeline to open to supplement the energy medium. During the supplementary energy medium, the system reads the liquid level of the supplementary energy medium in the regenerative buffer tank through the regenerative buffer tank liquid level detection device in real time, and when the liquid level reaches the set supplementary liquid level, the electric control valve is controlled to be closed to stop the supplementary energy medium. Through the above functions, the air energy heat pump can always have a normal amount of energy medium for use, so that the heating effect is stable, the system power consumption is stable, and the system power consumption is not additionally increased, thereby achieving the energy saving effect.

[0072] Start supplementary energy medium function judgment logic: The regenerative buffer tank liquid level is less than or equal to the system-set supplementary liquid level, and the supplementary energy medium function is started.

[0073] Stop supplementary energy medium function judgment logic: The regenerative buffer tank liquid level is greater than or equal to the system-set stop supplementary liquid level, and the supplementary energy medium function is stopped.

[0074] For the control of the auxiliary heating of the energy storage tank, the system reads the temperature of the energy medium in the energy storage tank through the temperature detection device of the energy storage tank, and then combines the indoor temperature, the user demand temperature, the temperature of the energy medium in the energy buffer tank and other parameters to make a logical judgment, so as to determine whether the auxiliary heater in the energy storage tank performs auxiliary heating. When the energy storage tank is used for auxiliary heating, the heating of the energy in the tank can be accelerated, and the loss of heat energy can be avoided, so that the energy saving effect can be achieved. At the same time, when the system starts the auxiliary heating of the energy storage tank, the system also reads the temperature of the heat energy in the energy storage tank in real time through the temperature detection device of the energy storage tank, and then combines the indoor temperature and the user demand temperature to make a logical judgment, so as to control the heating assembly in the energy storage tank to stop auxiliary heating.

[0075] The auxiliary heating start-stop strategy of the energy storage tank comprises: The auxiliary heating start strategy of the energy storage tank comprises: When the continuous time of the single start of the auxiliary heating of the energy buffer tank is greater than 1 hour (this value can be adjusted by system setting and modification), and the temperature of the energy medium in the energy buffer tank is less than or equal to the user-set start heating temperature of the energy buffer tank, and the indoor temperature is less than the user-set indoor requirement temperature plus an error value, the auxiliary heating of the energy storage tank is started.

[0076] When the auxiliary heating of the energy buffer tank is damaged or the outdoor temperature is too low to cause the heating effect of the air energy heat pump plus the auxiliary heating effect of the energy buffer tank to be still not as expected and the user demand temperature to be not reached, the system automatically confirms whether the indoor temperature is too low, that is, whether the indoor temperature is less than the user-set indoor requirement temperature plus an error value, and when the judgment condition is met, the system immediately starts the auxiliary heating function of the energy storage tank.

[0077] The auxiliary heating stop strategy of the energy storage tank comprises: When the temperature of the energy medium in the energy buffer tank is greater than or equal to the user-set stop heating temperature, or the indoor temperature is greater than the user-set indoor requirement temperature minus 2 (this value can be adjusted by system user software setting and modification), the auxiliary heater of the energy storage tank is turned off.

[0078] Further, an embodiment of the present application also provides a storage medium having a computer program stored thereon, and the program is executed by a controller to realize the hotel cooling and heating energy saving method as described above. It should be understood that each scheme in the embodiment has the corresponding technical effect in the method embodiment described above, which will not be repeated here.

[0079] Further, an embodiment of the present application also provides a computer program product, which is tangibly stored on a computer readable medium and includes computer readable instructions that, when executed, cause at least one controller to perform a hotel cooling and heating energy saving method such as in the embodiments described above.
