[0002] Heat pumps are a relatively new type of hot water production equipment. Powered by electricity, they are easy to install and can provide heating year-round and cooling in summer. They are a highly efficient, energy-saving, and pollution-free technology utilizing renewable energy. Compared to electric boilers and other similar equipment, heat pumps have higher heating capacity, lower costs, and place less pressure on the power supply. Furthermore, heat pumps can be used as energy storage devices, utilizing off-peak electricity at night to produce hot water at a certain temperature and storing it in an insulated tank. In recent years, with the increasing emphasis on energy conservation and environmental protection in my country, heat pumps have been widely adopted.

[0003] However, users have different needs based on different temperatures and humidity levels. Therefore, an adaptive heat pump is needed that can select one of multiple operating modes according to the ambient temperature and humidity and the user's needs, thereby improving the unit's energy efficiency and meeting the user's usage requirements. Summary of the Invention

[0028] When the heat pump system is in automatic switching mode, this invention determines the target system mode of the heat pump system based on the parameter information of the current environment and extracts the control strategy corresponding to the target system mode; responds to the system scenario selected by the user and adjusts the control strategy according to the system scenario; controls the operation of the host unit, fresh air unit and fan coil unit based on the adjusted control strategy, thereby improving the controllability of the operation of the heat pump system and thus improving the automation and comfort of the heat pump.

[0029] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” or “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0030] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 The first embodiment of the operation control method for a heat pump system in this invention includes:

[0031] 101. When the heat pump system is in automatic switching mode, acquire the parameter information of the current environment, determine the target system mode of the heat pump system based on the parameter information, and extract the control strategy corresponding to the target system mode.

[0032] Determine if the heat pump system is in a locked state. If not, check if the heat pump system is in an automatic switching state or a manual setting state. If the system is in an automatic switching state, proceed to obtain the current environmental parameter information and determine the target system mode of the heat pump system based on the parameter information. If the system is in a manual setting state, respond to the user's selection operation and adjust to the corresponding system mode based on the user's selection operation.

[0033] Furthermore, obtain the flag bit related to the working status of the heat pump system, and check whether the flag bit is 1 or 0. If the flag bit is 1, it is determined that the working status of the heat pump system is locked. If the flag bit is 0, the step of determining whether the working status of the heat pump system is automatic switching or manual setting is executed.

[0034] The acquired environmental parameters include the outdoor temperature, outdoor humidity, indoor temperature, indoor humidity, and the current system mode of the heat pump system in the area where the heat pump system is located.

[0035] Furthermore, after determining the target system mode, it is determined whether the current system mode of the heat pump system is the same as the target system mode. If the current system mode is different from the target system mode, the current running time of the heat pump system is obtained, and it is checked whether the minimum running time of the system mode is met. If not, the heat pump system is controlled to maintain the current system mode and continue to run. If it is met, the step of extracting the control strategy corresponding to the target system mode is executed. If the current system mode is the same as the target system mode, the running time of the target system mode is obtained, and it is determined whether the running time meets the preset running time. If not, the step of sending the working parameters to the corresponding unit to be operated and adjusting the unit to be operated based on the working parameters is executed. If it is met, the unit to be operated is controlled to automatically adjust within the preset working parameter range.

[0036] For example, if the runtime of the target system mode does not meet the preset runtime, when the outdoor temperature is not less than 20℃, the output target outlet water temperature is 35℃; when the outdoor temperature is between -10℃ and 20℃, the output target outlet water temperature is 0.5×outdoor temperature + 45℃; when the outdoor temperature is not greater than -10℃, the output target outlet water temperature is ∈ [the lower limit of automatic adjustment of heating outlet water temperature, the upper limit of automatic adjustment of heating outlet water temperature].

[0037] If the runtime of the target system mode does not meet the preset runtime, the target outlet water temperature of the main unit is selected as the maximum value between the outlet dew point of the fresh air unit and the room temperature.

[0038] When the system mode is in manual switching mode, it responds to the user's second selection operation, adjusts to the corresponding system mode based on the second selection operation, and obtains the current environmental data information within a specific time period to determine whether the data information meets the working parameters of the heat pump system after adjusting to the corresponding system mode; if not, it switches the system mode based on the data information.

[0039] 102. Respond to the user's first selection operation, determine the corresponding system scenario based on the first selection operation, and adjust the control strategy according to the system scenario;

[0040] Users select a system scene through the control panel associated with the heat pump system. These scenes include: Home Scene, Gathering Scene, Odor Removal Scene, Energy Saving Scene, Sleep Scene, and Away Scene. The system then retrieves the corresponding operating strategy, determines the operating parameters to be adjusted from the processing strategy based on this strategy, and corrects these parameters.

[0041] Furthermore, the operating parameters of the control strategy include the target outlet water temperature of the main unit, the outlet dew point temperature of the fresh air unit, the opening degree of the fresh air valve of the fan coil unit, and the output ratio of the fresh air unit's fan. For example, after determining the corresponding system scenario, the outdoor PM2.5 concentration and indoor carbon dioxide concentration are obtained. Based on the target system mode, outdoor PM2.5 concentration, and indoor carbon dioxide concentration, it is determined whether the current environment is suitable for opening windows, and the determination result is displayed on the control panel connected to the heat pump system. The external static pressure of the fresh air unit is adjusted based on the corresponding system scenario, thereby adjusting the overall fresh air volume level of the house. Furthermore, if the corresponding system scenario is determined to be energy-saving mode or away-from-home mode, the gateway unit can be controlled to operate in an energy-saving manner.

[0042] 103. Control the operation of the main unit, fresh air unit and fan coil unit based on the adjusted control strategy.

[0043] If the system mode is cooling mode, the indoor temperature is relatively constant, and the FCU controls the indoor temperature. The FAU primarily controls the indoor humidity, and secondarily assists in regulating the indoor temperature. The output control strategy is for the HP to output cooling capacity to the FAU and FCU to regulate the indoor temperature and humidity. If the system mode is heating mode, the indoor temperature is relatively constant, and the FCU controls the indoor temperature. The FAU controls the indoor humidity, and the output control strategy is for the HP to output heat capacity to the FCU to regulate the indoor temperature. The FAU operates but does not receive heat from the HP. If the system mode is ventilation mode, the indoor temperature and humidity may fluctuate with the outdoor conditions. The output control strategy is for the HP to be turned off. The FAU operates with 100% fresh air, regulating the indoor temperature and humidity with fresh air of suitable outdoor temperature and humidity. If the system mode is dehumidification mode, except at the beginning of system operation, the system dehumidifies mainly the outdoor humidity rather than the indoor humidity. In this mode, the indoor temperature may fluctuate with the outdoor conditions, and the output control strategy is for the HP to output cooling capacity to the FAU to regulate the indoor humidity.

[0044] In this embodiment of the invention, when the heat pump system is in automatic switching mode, the target system mode of the heat pump system is determined based on the parameter information of the current environment, and the control strategy corresponding to the target system mode is extracted; the system scenario selected by the user is responded to, and the control strategy is adjusted according to the system scenario; the host unit, fresh air unit and fan coil unit are controlled to work based on the adjusted control strategy, thereby improving the controllability of the operation of the heat pump system and thus improving the automation and comfort of the heat pump.

[0045] Please see Figure 2 The second embodiment of the operation control method for the heat pump system in this invention includes:

[0046] 201. When the heat pump system is in automatic switching mode, acquire outdoor temperature information, outdoor humidity information, indoor temperature information, and indoor humidity information of the area where the heat pump system is currently located;

[0047] Check whether the heat pump system switch is started, whether the heat pump system initialization is completed, whether there is a system event lock, and whether the current system operation mode is the linkage mode. If all the above conditions are met, output the system initialization command and read all unit parameters based on the system initialization completion command; if the conditions are not met, output the system event lock command.

[0048] Furthermore, if the current system is in linkage mode, all units of the heat pump system are automatically coordinated by the gateway. The main operating parameters of all units in the linkage system are issued by the gateway, but the unit can independently turn off the linkage switch and not respond to the parameters issued by the gateway. The unit is controlled locally and performs the steps to determine the system mode. The system mode includes automatic switching mode and manual switching mode. If the current system is not in linkage mode, the heat pump system is determined to be in commissioning mode. The heat pump system executes a pre-set dedicated commissioning process and adjusts the operating parameters of the heat pump system.

[0049] 202. Compare the outdoor temperature information, outdoor humidity information, indoor temperature information, and indoor humidity information with the judgment conditions corresponding to each system mode in sequence to determine the target system mode of the heat pump system.

[0050] When the target system mode is not in cooling mode, determine whether the outdoor temperature information is not less than the minimum outdoor temperature that allows the system to cool; determine whether the outdoor temperature information is within the outdoor heat temperature range; determine whether the indoor temperature information is within the indoor heat temperature range; if the outdoor temperature information is not less than the minimum outdoor temperature that allows the system to cool and the indoor temperature information is within the indoor heat temperature range, or if the outdoor temperature information is not less than the minimum outdoor temperature that allows the system to cool and the outdoor temperature information is within the outdoor heat temperature range, then determine that the target system mode of the heat pump system is cooling mode.

[0051] Furthermore, when the outdoor temperature is not less than 24°C and not less than the lowest room cooling target temperature, it falls within the outdoor temperature range of outdoor heat.

[0052] When the system is in heating mode, if the highest room heating target temperature is ≥18℃ and a room thermostat has a room temperature overshoot of >2.5℃, or if the lowest room cooling target temperature is not less than ≥24℃ and >50% of the room thermostats have a room temperature overshoot of >1.5℃, the output indoor temperature information is within the indoor heating temperature range.

[0053] When the system mode is cooling, if the lowest room cooling target temperature is ≥24℃ and a room thermostat has a room temperature overshoot of >2.5℃, or if the lowest room cooling target temperature is not less than ≥24℃ and >50% of the room thermostats have a room temperature overshoot of >1.5℃, the output indoor temperature information is within the indoor heating temperature range.

[0054] If the outdoor temperature information is lower than the minimum outdoor temperature that the system can cool, or if neither the indoor temperature information nor the outdoor temperature information is within the hot temperature range, determine whether the outdoor temperature information is not greater than the maximum outdoor temperature that the system can heat, and determine whether the outdoor temperature information is within the preset outdoor cold range or whether the indoor temperature information is within the preset indoor cold range.

[0055] Furthermore, when the outdoor temperature information is not greater than the highest room heating target temperature and the outdoor temperature information is not greater than 22°C, the output outdoor temperature information falls within the preset outdoor cold range.

[0056] When the system mode is cooling, if the lowest room cooling target temperature is ≤29℃ and a room thermostat has a room temperature overshoot of <-2.5℃, or if the lowest room cooling target temperature is not less than ≥24℃ and >50% of the room thermostats have a room temperature overshoot of <-1.5℃, the system outputs indoor temperature information to determine if it falls within the preset indoor cold range.

[0057] When the system mode is heating, if the highest room heating target temperature is ≤24℃ and a room thermostat has a room temperature overshoot of <-2.5℃, or if the lowest room cooling target temperature is not less than ≥24℃ and >50% of the room thermostats have a room temperature overshoot of <-1.5℃, the system will output indoor temperature information to determine if it falls within the preset indoor cold range.

[0058] If the outdoor temperature information is not greater than the maximum outdoor temperature that the system can heat and the outdoor temperature information is within the preset outdoor cold range, or if the outdoor temperature information is not greater than the maximum outdoor temperature that the system can heat and the indoor temperature information is within the preset indoor cold range, then the target system mode of the heat pump system is determined to be the heating mode.

[0059] If the outdoor temperature information is greater than the maximum outdoor temperature that the system can heat, or if neither the outdoor temperature information nor the indoor temperature information is within the preset cold range, then the system will determine whether the indoor temperature is within the humid range based on the indoor humidity information, or determine whether the outdoor temperature is within the cold and damp temperature range based on the outdoor temperature information and the outdoor humidity information.

[0060] Furthermore, when the outdoor temperature is less than 25°C and the outdoor dew point temperature is greater than the minimum allowable dew point temperature for the room, the output temperature falls within the range of outdoor damp and cold.

[0061] If the indoor humidity information is determined to be within the indoor damp range, or the outdoor temperature and humidity information are determined to be within the outdoor cold and damp temperature range, then the target system mode of the heat pump system is determined to be dehumidification mode; if the indoor humidity information is determined not to be within the indoor damp range, and the outdoor temperature and humidity information are determined not to be within the outdoor cold and damp temperature range, then the target system mode of the heat pump system is determined to be ventilation mode.

[0062] 203. Match the control strategy corresponding to the target system mode from the preset correspondence between system modes and control strategies;

[0063] 204. Respond to the user's first selection operation, determine the corresponding system scenario based on the first selection operation, and adjust the control strategy according to the system scenario;

[0064] If the system scenario is a sleep scenario or an away-from-home scenario, identify whether a timer switch is set; if a timer switch is set and the user selects the sleep scenario mode, determine whether the current system time is between the fall asleep time and the wake-up time; if so, output the system scenario mode as sleep mode; if a timer switch is set and the user selects the away-from-home scenario, determine whether the current system time is between the leave time and the return time; if so, output the system scenario mode as away-from-home mode; if no timer switch is set, output the system scenario mode as home mode.

[0065] For example, when the system scenario is a gathering scenario, the response speed of temperature and CO2 regulation in the activity area should be increased, the air volume in the quiet zone should be reduced to increase the air volume in the active zone, and the overall air volume and fresh air volume should be increased; when the system scenario is an odor removal scenario, the indoor air should be replaced more quickly, the system should operate with 100% fresh air, and the maximum air volume should be used; when the system scenario is an energy-saving scenario, the fresh air volume should be reduced and the main unit frequency should be limited.

[0066] 205. Control the operation of the main unit, fresh air unit and fan coil unit based on the adjusted control strategy.

[0067] After the control unit, fresh air unit, and fan coil unit complete their work, each unit should send the relevant information regarding parameter changes to the gateway unit in the form of {address information, control parameters}. Alternatively, after the gateway unit completes any parameter change, it should send the information to all relevant unit devices. Verify that the system switch is in the ON state, there are no locked system events, the heat pump is operating in system linkage mode, and output a command to shut down the heat pump system.

[0068] In this embodiment of the invention, when the heat pump system is in automatic switching mode, the target system mode of the heat pump system is determined based on the parameter information of the current environment, and the control strategy corresponding to the target system mode is extracted; the system scenario selected by the user is responded to, and the control strategy is adjusted according to the system scenario; the host unit, fresh air unit and fan coil unit are controlled to work based on the adjusted control strategy, thereby improving the controllability of the operation of the heat pump system and thus improving the automation and comfort of the heat pump.

[0069] Please see Figure 3 A third embodiment of the operation control method for a heat pump system in this invention includes:

[0070] 301. When the heat pump system is in automatic switching mode, acquire the parameter information of the current environment, determine the target system mode of the heat pump system based on the parameter information, and extract the control strategy corresponding to the target system mode.

[0071] The main unit is the heat source and cold source of the heat pump system. The heat pump system also includes FAU (fresh air unit), which mainly controls the CO2 concentration and humidity in each room of the system; FCU (fan coil unit), which mainly controls the room temperature and the opening of the fresh air valve. The FCU is directly controlled by RT (room thermostat); and GW (gateway), which is mainly responsible for communication and linkage between the various units of the system.

[0072] The gateway obtains the division of the residential area or the floor information of the residential area to which the heat pump system belongs. Based on the division of the residential area or the floor information, it obtains the operating parameters of all fresh air units in the residential area and the operating parameters of all main unit inside and outside the residential area. The residential area (system) consists of several areas or floors containing rooms. Each FAU corresponds to one area, that is, the number of areas is the number of FAUs, and each RT corresponds to one room.

[0073] After obtaining the area division information, the heat pump is powered on and initialized. Data packets of all host units, room thermostats and fresh air units associated with the heat pump are obtained, and the parameters of the heat pump's gateway unit are initialized.

[0074] Furthermore, the gateway obtains or updates the topology of all device units in the heat pump system from the cloud. In principle, the central control only interacts with the unit devices, not with their sub-devices or components. Direct communication and linkage between device units are not allowed; all communication and linkage are handled by the central control, except for the HP-FAU refrigerant heater. Based on the principle of proximity, timely feedback controls are determined and executed locally by the device unit, while long-cycle feedback controls at the system level are determined and sent by the central control. For example, calculating the target dew point temperature of the FAU outlet air every 1800 seconds is a case of a relatively long adjustment feedback cycle, and therefore should be determined and sent by the central control.

[0075] 302. Respond to the user's first selection operation, determine the corresponding system scenario based on the first selection operation, and adjust the control strategy according to the system scenario;

[0076] The system detects the user's first selection operation on the control panel, identifies the first selection operation, and determines the form of the first selection operation. If the first selection operation is a swipe, the corresponding system scene is determined based on the distance and direction of the user's swipe. If the first selection operation is a click, the system scene corresponding to the first selection operation is determined based on the click location information and the correspondence between preset location information and system scenes.

[0077] 303. Analyze the adjusted control strategy to obtain the target outlet water temperature of the main unit, and control the outlet water temperature of the main unit to reach the target outlet water temperature.

[0078] After analyzing and adjusting the control strategy, determine whether the main unit's outlet water temperature is in automatic or manual adjustment mode. In automatic mode, calculate the target outlet water temperature of the main unit based on the target system mode every preset outlet water temperature adjustment cycle. In manual mode, determine the target outlet water temperature of the main unit based on the user-set outlet water temperature. When calculating the required current and target supply water temperatures for each area, the supply water temperature of the main unit should be determined using the most unfavorable parameter principle.

[0079] Furthermore, the heat pump system is connected to Moji Cloud Weather and obtains the current weather temperature value from Moji Cloud Weather in real time. (1) When the outdoor humidity is relatively high, the fresh air unit undertakes the dehumidification task: when the outdoor dew point temperature is higher than the lowest room allowable dew point temperature limit, the output FAU outlet target dew point temperature is between the lowest room allowable dew point temperature limit and the fresh air outlet dew point temperature compensation value during dehumidification, that is, the FAU outlet target dew point temperature ∈ [11℃, 16℃]; (2) When the outdoor humidity is relatively low, the fresh air unit undertakes the humidification task: when the outdoor dew point temperature is lower than the highest room allowable dew point temperature limit, the output FAU outlet target dew point temperature is between the highest room allowable dew point temperature limit and the fresh air outlet dew point temperature compensation value during humidification, that is, the FAU outlet target dew point temperature ∈ [7.5℃, 13℃]; (3) When the outdoor humidity is suitable, the fresh air does not need to be humidified or dehumidified: when neither (1) nor (2) above is satisfied, the output FAU outlet target dew point temperature is the outdoor dew point temperature.

[0080] 304. When the target system mode is cooling mode, adjust the outlet dew point temperature of the fresh air unit and the opening degree of the fresh air valve of the fan coil unit based on the cooling capacity provided by the host unit, and control the first output ratio of the fresh air unit fan.

[0081] In cooling mode, the gateway sends a command to the host unit to heat the water to the target outlet temperature. The host unit then provides cooling to the fresh air unit and the fan coil unit based on this command. The gateway sends the target dew point temperature of the outlet air to the fresh air unit and controls the minimum output ratio of the fresh air unit's fan to 20% in cooling mode.

[0082] 305. When the target system mode is heating mode, the opening of the fresh air valve of the fan coil unit is adjusted based on the heat provided by the host unit, and the fresh air unit is controlled to operate but does not receive heat provided by the host unit.

[0083] In heating mode, the gateway sends a command to the host unit to heat the water to the target outlet temperature. The host unit then provides heat to the fresh air unit and the fan coil unit based on this command. The gateway sends the target dew point temperature of the outlet air to the fresh air unit and controls the minimum output ratio of the fresh air unit's fan to 20% in heating mode.

[0084] 306. When the target system mode is ventilation mode, shut down the main unit, adjust the outlet dew point temperature of the fresh air unit, and control the second output ratio of the fresh air unit fan.

[0085] In ventilation mode, the gateway does not send commands to the host unit; the gateway sends the target dew point temperature of the air outlet to the fresh air unit and controls the minimum output ratio of the fresh air unit's fan to 20% in heating mode.

[0086] 307. When the target system mode is dehumidification mode, adjust the opening of the fresh air valve of the fan coil unit based on the cooling capacity provided by the main unit.

[0087] In dehumidification mode, the gateway unit is set to cooling mode; the gateway sends the target dew point temperature of the air outlet to the fresh air unit and controls the minimum output ratio of the fresh air unit's fan to 40% in heating mode.

[0088] In this embodiment of the invention, when the heat pump system is in automatic switching mode, the target system mode of the heat pump system is determined based on the parameter information of the current environment, and the control strategy corresponding to the target system mode is extracted; the system scenario selected by the user is responded to, and the control strategy is adjusted according to the system scenario; the host unit, fresh air unit and fan coil unit are controlled to work based on the adjusted control strategy, thereby improving the controllability of the operation of the heat pump system and thus improving the automation and comfort of the heat pump.

[0103] When the target system mode is not in cooling mode, the system determines whether the outdoor temperature information is not less than the minimum outdoor temperature allowed for system cooling; whether the outdoor temperature information falls within the hot temperature range; and whether the indoor temperature information falls within the hot temperature range. If the outdoor temperature information is not less than the minimum outdoor temperature allowed for system cooling and the indoor temperature information falls within the hot temperature range, or if the outdoor temperature information is not less than the minimum outdoor temperature allowed for system cooling and the outdoor temperature information falls within the hot temperature range, then the target system mode of the heat pump system is determined to be cooling mode. If the outdoor temperature information is less than the minimum outdoor temperature allowed for system cooling, or if both the indoor and outdoor temperature information fall outside the hot temperature range, the system determines whether the outdoor temperature information is not greater than the maximum outdoor temperature allowed for system heating, and whether the outdoor temperature information falls within a preset cold range or whether the indoor temperature information falls within a preset cold range. If the outdoor temperature information is not greater than the maximum indoor temperature allowed for system heating... If the outdoor temperature is within a preset cold range, or if the outdoor temperature is not greater than the maximum outdoor temperature allowed for system heating and the indoor temperature is within a preset cold range, then the target system mode of the heat pump system is determined to be heating mode. If the outdoor temperature is greater than the maximum outdoor temperature allowed for system heating, or if both the outdoor and indoor temperatures are not within the preset cold range, then the system is determined to be either within a humid indoor range based on the indoor humidity information or within a cold and humid outdoor temperature range based on the outdoor temperature and humidity information. If the indoor humidity is determined to be within a humid indoor range or if both the outdoor temperature and humidity are within a cold and humid outdoor temperature range, then the target system mode of the heat pump system is determined to be dehumidification mode. If the indoor humidity is determined to be outside a humid indoor range and both the outdoor temperature and humidity are not within a cold and humid outdoor temperature range, then the target system mode of the heat pump system is determined to be ventilation mode.
