In different application scenarios, it is difficult for users to select a suitable control strategy, and there is a certain energy waste when multiple heating equipment is started. For example, the heating system composed of air source heat pump and gas wall-hanging stove for hot water heating is started according to user setting to open multi-split or wall-hanging stove heating (radiator) to realize single or simultaneous heating to improve the heating effect. The air source heat pump has high efficiency, but it is easy to frost in low temperature winter and lose capacity.

When the computer program is executed by the processor 1001, the above-described functions defined in the methods of the embodiments of the present disclosure are performed.
[0085] The environment regulation system provided by the present application can realize intelligent control of heat output of double heat sources in the environment regulation system by using the control method of the environment regulation system in the following embodiments, can fully exert the performance of multiple heating devices, can improve the operation energy efficiency of the environment regulation system while realizing intelligent and comfortable temperature control of the environment regulation system, and can avoid unnecessary energy waste. Compared with the prior art, the environment regulation system provided by the present application has the same beneficial effects as the control method of the environment regulation system provided by the following embodiments, and other technical features of the environment regulation system are the same as the features disclosed in the following embodiments, which will not be repeated here.
[0086] Based on this, in order to overcome the technical problems and defects existing in the prior art, the embodiment of the present application provides an environment regulation system control method, which is applied to an environment regulation system, the environment regulation system comprises a heat pump system and a carrier refrigerant circulation loop in heat exchange connection with the heat pump system, the heat pump system comprises a heat pump indoor unit, and the carrier refrigerant circulation loop comprises a terminal device, the heat pump indoor unit and the terminal device are arranged in a target area, and the environment regulation system control method comprises the steps that Figure 3 , Figure 3 The flowchart of the environment regulation system control method according to the first embodiment of the present application is shown in the figure, and the environment regulation system control method comprises the steps that
[0087] In step S10, the heat pump system is controlled to run in a heat exchange mode, and the indoor temperature of the target area is obtained.
[0088] The control method of the environment regulation system in the embodiment of the present application is applied to an environment regulation system composed of a heat pump system, a gas device and a terminal device, wherein the heat pump system refers to an air source heat pump multi-split unit (i.e. the heat pump system), which comprises a heat pump indoor unit, also known as a multi-split indoor unit. The air source heat pump mainly exchanges heat with air through internal compressed refrigerant circulation to realize heat transfer of different spaces or media, and the multi-split indoor unit is a direct expansion type, which is a room multi-split indoor unit taking refrigerant as a medium and exchanges heat with indoor air. Each air source heat pump multi-split unit corresponds to multiple multi-split indoor units, and each multi-split indoor unit corresponds to a room. In addition, the terminal device refers to a general term for a remote indoor heat exchange device of a water refrigeration or heating system, including floor heating, air disc, radiator and the like. The floor heating is a common form of indoor heat exchange terminal device, and the coil is arranged on the ground and water is circulated therein for heating. The target area refers to a room, and the control method of the environment regulation system in the embodiment of the present application can execute separate control strategies for different rooms (i.e. different target areas), thereby meeting the heating demand of each room.
[0089] In addition, the indoor temperature of the target area can be obtained by a return air temperature sensor or a sensor arranged in the room, which is not limited herein. The embodiment of the present application mainly controls the gas device adaptively when the heat pump system is in a heating mode, so as to realize automatic intelligent heat supplement. The gas device can be a gas wall-hanging stove, which is one of the components of the environment regulation system and is another heat source in the environment regulation system except the heat pump outdoor unit. The gas wall-hanging stove mainly releases heat by burning fuel such as natural gas, exchanges heat with water to obtain hot water, and supplies heat to the terminal device through a heating water circuit.
[0090] In addition, the intelligent heat supplement linkage related function display in the environment conditioning system at least includes the running state of the heat pump indoor unit and the running state of the terminal device in the room. After the intelligent heat supplement function of the environment conditioning system is turned on, the running states (on or off) of the heat pump indoor unit and the terminal device are recorded in real time, and then step S10 is executed to realize intelligent automatic heat supplement for the target area.
[0091] In step S20, the temperature achievement of the target area is determined according to the indoor temperature.
[0092] It can be understood that, in the case that the indoor temperature is obtained, the temperature achievement of the target area can be determined according to the set temperature received by the environment conditioning system. The temperature achievement can be a form of temperature reaching or not reaching, or a difference between the indoor temperature and the set temperature, which is used to represent the achievement of the target area with respect to the set temperature.
[0093] In step S30, the heat exchange amount of the heat pump indoor unit and the terminal device is adjusted according to the temperature achievement.
[0094] Finally, the heat exchange amount of the heat pump indoor unit and the terminal device is adjusted according to the temperature achievement of the target area. The heat pump indoor unit is heated by an air source heat pump, and the terminal device can be heated by the air source heat pump and a gas boiler. When the temperature achievement of the target area is different, different heat exchange amount strategies can be adopted by the heat pump indoor unit and the terminal device, so that the heat supply of the environment conditioning system is adapted to the temperature achievement. The temperature achievement can be qualitative analysis, including temperature reaching or not reaching, or quantitative analysis, such as the temperature difference between the indoor temperature and the set temperature.
[0095] For example, when the temperature achievement is temperature reaching, one of the heat pump indoor unit and the terminal device can be selected to keep heat exchange running, saving energy and improving energy efficiency. When the temperature achievement is not temperature reaching, both the heat pump indoor unit and the terminal device can be kept heat exchange running to quickly raise the indoor temperature and achieve the set temperature, improving user experience. Through the above control strategy, the dual-heat-source environment conditioning system can realize intelligent switching of the heat source and intelligent temperature control of the environment conditioning system.
[0096] In addition to selecting one of the heat supply devices to run, the output power of the heat pump indoor unit and the terminal device can also be controlled to adjust the heat exchange amount. Specifically, the worse the temperature achievement, the greater the total heat exchange amount of the heat pump indoor unit and the terminal device. In addition, the proportion of the heat exchange amount of the heat pump indoor unit in the total heat exchange amount can also be adjusted according to the outdoor environment temperature. The lower the temperature, the lower the energy efficiency of the heat pump indoor unit, and the proportion of the heat exchange amount of the heat pump indoor unit is also adjusted to be lower.
[0097] The embodiment of the present application provides a control method of an environment adjusting system, the environment adjusting system comprising a heat pump system and a carrier refrigerant circulation loop in heat exchange connection with the heat pump system, the heat pump system comprising a heat pump indoor unit, the carrier refrigerant circulation loop comprising a terminal device, the heat pump indoor unit and the terminal device being arranged in a target area, the control method of the environment adjusting system comprising: firstly controlling the heat pump system to run in a heat exchange mode, obtaining an indoor temperature of the target area, then determining a temperature achievement condition of the target area according to the indoor temperature, and finally adjusting heat exchange amounts of the heat pump indoor unit and the terminal device according to the temperature achievement condition, in the technical scheme of the present application, the temperature achievement condition of the target area is firstly determined based on the indoor temperature, and the heat supply amounts of the heat pump indoor unit and the terminal device are controlled based on the temperature achievement condition of the indoor temperature, so that the user does not need to manually control the operation of the gas equipment, the learning cost of the user on the control of the environment adjusting system is reduced, the adaptive environment adjusting control of the environment adjusting system is realized, the heat supply amounts of the gas equipment can be intelligently adjusted according to the current temperature achievement condition, the performance of the multiple heat supply equipment is fully brought into play, and the operation energy efficiency of the heat supply system is improved while the intelligent comfortable temperature control of the heat supply system is realized, so that the gas cost is saved.
[0098] Further, in a feasible embodiment, the step of determining the temperature achievement condition of the target area according to the indoor temperature comprises:
[0099] In step S21, a temperature difference between the indoor temperature and the set temperature is determined, and the temperature achievement condition comprises the temperature difference.
[0100] In the embodiment of the present application, the temperature difference between the indoor temperature and the set temperature is used to measure the temperature achievement condition of the target area, and it can be understood that, when the temperature difference between the indoor temperature and the set temperature is calculated, if the temperature difference is a positive value, the indoor temperature is higher than the set temperature, and if the temperature difference is a negative value, the indoor temperature is lower than the set temperature, therefore, the lower the temperature difference, the worse the temperature achievement condition of the indoor temperature, and more heat supply is needed, and the higher the temperature difference, the better the temperature achievement condition of the indoor temperature, so that the heat exchange amounts of the heat pump indoor unit and the terminal device can be appropriately adjusted, the total operation energy efficiency of the environment adjusting system is higher, and the energy consumption is saved.
[0101] In the embodiment of the present application, the temperature difference is used to represent the temperature achievement condition of the target area, so that the quantitative analysis of the temperature achievement condition of the target area is realized, and the appropriate temperature control strategy can be conveniently executed.
[0102] Further, on the basis of the above-mentioned embodiment, with reference to Figure 4 In the second embodiment, the step of adjusting the heat exchange amounts of the heat pump indoor unit and the terminal device according to the temperature achievement condition comprises:
[0103] Step S31, when the temperature difference is greater than or equal to a first preset temperature difference, controlling one of the heat pump indoor unit and the terminal device to heat; and / or,
[0104] Step S32, when the temperature difference is less than the first preset temperature difference and greater than or equal to a second preset temperature difference, controlling the heat pump indoor unit to maintain the current state and controlling the environment conditioning system to operate to make the terminal device in a heating state; and / or,
[0105] Step S33, when the temperature difference is less than a third preset temperature difference, controlling the heat pump indoor unit and the terminal device to heat.
[0106] Wherein, the first preset temperature difference is greater than the second preset temperature difference, the second preset temperature difference is greater than the third preset temperature difference, and the first preset temperature difference is greater than -1℃.
[0107] In the embodiment of the present application, the first preset temperature, the second preset temperature difference and the third preset temperature difference are used to divide the temperature difference into three different cases, wherein the first preset temperature difference is greater than 0, that is, the indoor temperature is greater than the set temperature, at this time, the indoor temperature can meet the user's demand, and one of the heat pump indoor unit and the terminal device can be controlled to heat (such as randomly selecting one heating device to keep running) to meet the heating demand, which can meet the indoor heating demand while keeping low energy consumption, so as to avoid the waste of electric energy or gas caused by simultaneously starting the heat pump indoor unit and the terminal device.
[0108] Wherein, the current state of the heat pump indoor unit can be open or closed, if the heat pump indoor unit is currently closed, it is maintained closed, and if the heat pump indoor unit is currently open, it is maintained open, and when the temperature difference is less than the first preset temperature difference, the heating capacity of the terminal device is increased at the same time.
[0109] In addition, when the temperature difference is less than the first preset temperature difference and greater than or equal to the second preset error, it indicates that the indoor temperature cannot completely reach the set temperature, but the difference between the indoor temperature and the set temperature is not too far, at this time, the heat pump indoor unit can be controlled to maintain the current state and the environment conditioning system can be controlled to operate to make the terminal device in a heating state, so that the indoor temperature is quickly reached to the set temperature through the heating of the terminal device, and the user's comfort is improved.
[0110] When the temperature difference is less than the third preset temperature difference, the indoor temperature and the set temperature are greatly different, and the heat pump indoor unit and the terminal device need to be controlled to heat at the same time to provide the maximum heating capacity to the target area, so that the indoor temperature of the target area is quickly increased.
[0111] It should be noted that, compared with step S32, the total heating capacity of the heat pump indoor unit and the terminal device in step S33 is greater than the total heating capacity of the heat pump indoor unit and the terminal device in step S32.
[0112] Exemplarily, in order to facilitate understanding, the above three different temperature reaching situations can be divided into a temperature reaching zone, a near temperature zone and a far temperature zone, which can be converted with each other with the change of indoor temperature, wherein the first preset temperature difference can be 0℃ or 1℃, the second preset temperature difference can be -1℃ or 0℃, and the third preset temperature difference can be 0℃ or -1℃. For example, the temperature reaching zone ∈ [0, 2]℃, by default [1, 2]℃; the near temperature zone ∈ [-1, 0]℃, by default [0, 1]℃; and the far temperature zone ∈ [-30, 0]℃, by default [-30, -1]℃, wherein the boundaries of the temperature ranges of the three zones can not be adjacent (for example, the lower boundary of the temperature reaching zone can not be equal to the upper boundary of the near temperature zone), because in the environmental regulation system, when setting the temperature difference threshold, a certain temperature hysteresis can be considered, because the temperature fluctuates frequently, in order to avoid the frequent change of control frequency caused by the temperature difference repeatedly changing between two zones due to temperature fluctuation, and maintain the stability of the temperature control strategy of the environmental regulation system, so a certain temperature hysteresis can be set to discretely set each zone.
[0113] Further, in a feasible embodiment, in step S31, the step of controlling one of the heat pump indoor unit and the terminal device to operate in heating mode includes:
[0114] Step S311, in the case that the heat pump indoor unit and the terminal device are both in heating state, controlling one of the heat pump indoor unit and the terminal device to operate in heating mode according to outdoor environment temperature; and / or,
[0115] Step S312, in the case that the heat pump indoor unit is in heating state and the terminal device is in stop heating state, keeping the heat pump indoor unit operating; and / or,
[0116] Step S313, in the case that the heat pump indoor unit is in stop heating state and the terminal device is in heating state, controlling the heat exchange amount of the terminal device according to the target cold carrier temperature of the terminal device and outdoor environment temperature.
[0117] In the embodiment of the present application, when the indoor temperature is greater than the set temperature, and both the heat pump indoor unit and the terminal device are in the heating state, in order to avoid energy waste and excessive indoor temperature rise, one of the heating devices can be selected to be closed, and in the embodiment of the present application, one of the heat pump indoor unit and the terminal device can be selected to be maintained to operate according to the outdoor environment temperature. Since the heat pump indoor unit is heated by the air source heat pump, the terminal device is heated by the air source heat pump and / or the gas device, and the characteristic of the air source heat pump is that the higher the outdoor environment temperature, the higher the operating energy efficiency, and the lower the outdoor environment temperature, the lower the operating energy efficiency. Therefore, when the outdoor environment temperature is high, the heat pump indoor unit can be controlled to maintain heating operation, and when the outdoor environment temperature is low, the terminal device can be controlled to maintain heating operation.
[0118] In addition, when the heat pump indoor unit is in the heating state and the terminal device is in the stop heating state, the heat pump indoor unit is maintained to operate, the set state of the user can be respected, and the operation of the heat pump indoor unit can be maintained.
[0119] When the heat pump indoor unit is in the stop heating state and the terminal device is in the heating state, the heat exchange amount of the terminal device is controlled according to the target refrigerant temperature of the terminal device and the outdoor environment temperature, wherein the higher the target refrigerant temperature of the terminal device, the higher the heating demand, and the heat exchange amount of the terminal device can be correspondingly increased, and vice versa, the heat exchange amount of the terminal device is reduced; and the lower the outdoor environment temperature, the lower the water supply temperature, so the higher the heating demand, and the heat exchange amount of the terminal device needs to be increased, and vice versa, the heat exchange amount of the terminal device is reduced, until the terminal device reaches the target refrigerant temperature, and the heat exchange amount of the terminal device is stopped to be adjusted.
[0120] In another possible embodiment, when the heat pump indoor unit is in the stop heating state and the terminal device is in the heating state, the heat pump indoor unit can also be selected to be started and the terminal device can be selected to be closed according to the outdoor environment temperature (greater than the first preset temperature).
[0121] In the embodiment of the present application, according to different operating states of the current heat pump indoor unit and the terminal device, a suitable control strategy is selected to make the environment conditioning system reduce energy consumption when the target area is in the temperature reaching state, and at the same time, stable heating capacity can be maintained, so that the indoor temperature can be maintained at a certain level, and stable heating experience can be provided to the user.
[0122] Further, in a possible embodiment, the step of controlling one of the heat pump indoor unit and the terminal device to heat operates according to the outdoor environment temperature, and the step includes:
[0123] Step A10, when the outdoor environment temperature is higher than the first preset air temperature, the terminal device is controlled to be closed, and the heat pump indoor unit is controlled to maintain heating operation;
[0124] Step A20, when the outdoor ambient temperature is not higher than the first preset air temperature, controlling the heat pump indoor unit to be closed, and controlling the terminal device to maintain the heating operation.
[0125] In the case of selecting one of the heat pump indoor unit or the terminal device to be closed according to the outdoor ambient temperature, the determination can be made based on a first preset air temperature, which is used to represent a critical temperature value of the operating energy efficiency of the heat pump indoor unit and the terminal device respectively. When the outdoor ambient temperature is higher than the first preset air temperature, the operating energy efficiency of the heat pump indoor unit is higher than that of the terminal device, so the heating operation of the heat pump indoor unit is maintained and the terminal device is closed. When the outdoor ambient temperature is not higher than the first preset air temperature, the operating energy efficiency of the heat pump indoor unit is lower than that of the terminal device, so the heating operation of the terminal device is maintained and the heat pump indoor unit is closed.
[0126] In another possible embodiment, considering the temperature hysteresis, the first preset air temperature can include two thresholds: a and b, where b≥a, b∈[3,10]℃, and the default is 7℃; a∈[-10,5]℃, and the default is 3℃. When the outdoor ambient temperature is higher than 7℃, the terminal device is controlled to be closed and the heat pump indoor unit is controlled to maintain the heating operation. When the outdoor ambient temperature is lower than 3℃, the heat pump indoor unit is controlled to be closed and the terminal device is controlled to maintain the heating operation. In particular, when the outdoor ambient temperature is higher than 3℃ and lower than 7℃, the operating states of the heat pump indoor unit and the terminal device remain unchanged.
[0127] In the embodiments of the present application, the outdoor ambient temperature is measured by the first preset air temperature, and the operating states of the heat pump indoor unit and the terminal device are controlled. Combining the characteristics that the operating energy efficiency of the heat pump system is affected by the outdoor ambient temperature, the waste of energy (electricity or gas energy) is avoided, and the operating energy efficiency of the environmental regulation system is effectively improved.
[0128] Further, in one possible embodiment, the environmental regulation system further comprises a gas device, which is in heat exchange connection with the refrigerant circulation circuit and is used to supply heat for the terminal device. The step of controlling the heat exchange amount of the terminal device according to the target cold carrier temperature and the outdoor ambient temperature comprises:
[0129] Step B10, when the target cold carrier temperature is not higher than the preset cold carrier temperature or the outdoor ambient temperature is not lower than the second preset air temperature, controlling the gas device to be closed;
[0130] Step B20, when the target cold carrier temperature is higher than the preset cold carrier temperature and the outdoor ambient temperature is lower than the second preset air temperature, controlling the gas device to operate.
[0131] In the embodiment of the present application, whether the gas device needs to be started in the case that the indoor temperature is up to the temperature is determined by two conditions of the preset cold carrier temperature and the second preset air temperature. Specifically, the target cold carrier temperature is the target temperature corresponding to the terminal device, for example, the water temperature of the heat dissipation part of the floor heating. The higher the target cold carrier temperature, the more heat supply is needed. The preset cold carrier temperature is a preset temperature determined by experience in advance, and its characteristics are that when the target cold carrier temperature of the terminal device is higher than the preset cold carrier temperature and the outdoor environment temperature is low, the auxiliary heating of the gas device is needed to make the water temperature in the terminal reach the target cold carrier temperature. On the other hand, the influence of the outdoor environment temperature on the water temperature is also considered. It can be understood that when the outdoor environment temperature is high, the water supply temperature is also high, so the gas device does not need to be started for heating. When the outdoor environment temperature is lower than the second preset temperature, and the target cold carrier temperature is higher than the preset cold carrier temperature, the gas device needs to be started for heating.
[0132] Exemplarily, the preset cold carrier temperature: TWy∈[35, 60]℃, and the default is 50℃. The second preset air temperature∈[-30, -7]℃, and the default is -25℃.
[0133] In the embodiment of the present application, whether the gas device needs to be controlled to run for heating is determined by combining the cold carrier temperature of the terminal device and the outdoor environment temperature, which realizes the adaptive intelligent control of the gas device, does not cause energy waste, and guarantees the heating effect in the room.
[0134] Further, in a feasible embodiment, the environment adjusting system further comprises a gas device, which is in heat exchange connection with the refrigerant circulation loop, and is used for supplying heat for the terminal device. The steps of controlling the heat pump indoor unit to maintain the current state running and controlling the environment adjusting system to run so that the terminal device is in the heating state comprise:
[0135] Step S321, controlling the heat pump indoor unit to maintain the current state running.
[0136] Step S322, controlling the gas device to run based on the preset output power.
[0137] Wherein, when the temperature difference is greater than the first preset temperature difference and greater than or equal to the second preset temperature difference, it can be determined that the target area belongs to the near temperature area. At this time, the indoor temperature is not much different from the set temperature, and the temperature control strategy of increasing the heat supply can be adopted. Specifically, the gas device is used for heating, and the heat pump indoor unit can maintain the original current state unchanged, wherein the current state of the heat pump indoor unit is the running state set by the user.
[0138] In the control of the gas equipment, the gas equipment is operated at a preset output power, and the preset output power is a high water temperature, for example, the highest heating gear of the gas equipment, so that the water level of the terminal equipment rises rapidly, and the indoor temperature of the target area reaches the set temperature as soon as possible.
[0139] In the embodiment of the present application, the heating state of the gas equipment is started in the near temperature zone, so that the indoor temperature rises rapidly to reach the set temperature, and the heating experience of the user is improved.
[0140] Further, in a feasible embodiment, after the step of controlling the gas equipment to operate at a preset output power, the method further comprises:
[0141] In step S323, when the gas equipment operates at a preset output power for a preset time length or the temperature difference is greater than or equal to a first preset temperature difference, the terminal equipment and the heat pump indoor unit are controlled to return to the user set state.
[0142] It can be understood that after the gas equipment is operated in the high water temperature mode for a period of time, the heating amount needs to be appropriately reduced in order to avoid overheating. In the embodiment of the present application, the preset time length or the change of the temperature difference can be used to determine the timing of reducing the heating amount.
[0143] Specifically, after the gas equipment operates at a preset output power for a period of time, the gas equipment can be turned off, and the running state of the terminal equipment and the heat pump indoor unit is returned to the user set state, that is, the state manually set by the user before the control method of the environmental regulation system of the embodiment of the present application is executed.
[0144] Specifically, the user set state can include three cases: the terminal equipment is turned on and the heat pump indoor unit is turned off, the terminal equipment and the heat pump indoor unit are turned on at the same time, and the terminal equipment is turned off and the heat pump indoor unit is turned on.
[0145] In addition, when the temperature difference between the indoor temperature and the set temperature is greater than or equal to a first preset temperature difference, it can be determined that the target area has reached the temperature state, at which time the gas equipment does not need to continue to supply heat, and the gas equipment can also be turned off, and the running state of the terminal equipment and the heat pump indoor unit is returned to the user set state.
[0146] The embodiment of the present application provides a way to stop the gas equipment from supplying additional heat, which avoids the temperature of the target area being too high and reduces the waste of gas.
[0147] Further, in a feasible embodiment, the environmental regulation system further comprises a gas equipment, which is in heat exchange connection with the refrigerant circulation loop and is used to supply heat for the terminal equipment. After the step of controlling the heat pump indoor unit and the terminal equipment to operate for heating, the method further comprises:
[0148] Step S34, controlling the heat supply of the gas equipment according to the temperature of the secondary refrigerant in the secondary refrigerant circulation loop.
[0149] When the temperature difference between the indoor temperature of the target area and the set temperature is less than the third preset temperature difference, it can be considered that the target area belongs to the far temperature zone, and in this case, the heating functions of the heat pump indoor unit and the terminal equipment are started at the same time, which can provide the maximum power heat supply for the target area. In addition, the terminal equipment can be heated by the gas equipment, and in the process of heating by the gas equipment, the heat supply of the gas equipment can be controlled based on the temperature of the secondary refrigerant in the secondary refrigerant circulation loop.
[0150] Exemplarily, the secondary refrigerant circulation loop is a heating water circuit, the higher the water temperature in the water circuit, the less heat supply of the gas equipment is required, at this time the output power of the gas equipment can be reduced; the lower the water temperature, the more heat supply of the gas equipment is required, at this time the output power of the gas equipment can be increased to increase the water temperature.
[0151] Specifically, the output power adjustment mode of the gas wall-hanging stove includes: when increasing the output power of the gas wall-hanging stove, the gas proportional valve can be opened, the number of fire row ignitions can be increased, and air circulation can be increased; when reducing the output power of the gas wall-hanging stove, the gas proportional valve can be reduced, the number of fire row ignitions can be reduced, and air circulation can be reduced.
[0152] In the embodiment of the application, the heat supply of the gas equipment is adaptively adjusted according to the temperature of the secondary refrigerant, so that the water temperature in the heating water circuit is maintained at a high level, the heat supply of the terminal equipment is improved, and the indoor temperature rises rapidly.
[0153] Further, in a feasible embodiment, the secondary refrigerant circulation loop further comprises a heat exchange part, the secondary refrigerant temperature comprises at least a secondary refrigerant supply temperature of the heat exchange part and a target secondary refrigerant temperature of the terminal equipment, and the step of controlling the heat supply of the gas equipment according to the secondary refrigerant temperature in the secondary refrigerant circulation loop comprises:
[0154] Step S341, when the secondary refrigerant supply temperature is not higher than the target secondary refrigerant temperature of the terminal equipment, controlling the gas equipment to run and controlling the gas equipment to run according to the preset output power;
[0155] Step S342, when the secondary refrigerant supply temperature is higher than the target secondary refrigerant temperature of the terminal equipment, controlling the gas equipment to be closed.
[0156] The heat exchange part is a hydraulic module, the refrigerant supply temperature is the temperature of water flow supplied by the hydraulic module to the downstream (i.e. the terminal device), and the target refrigerant temperature of the terminal device is the target temperature required by the terminal device (such as floor heating) to make the indoor temperature reach the set temperature. Generally, considering heat dissipation, the water supply temperature of the hydraulic module cannot be lower than the target refrigerant temperature of the terminal device, so when the refrigerant supply temperature is not higher than the target refrigerant temperature of the terminal device, the gas device needs to be used for heat compensation, wherein the preset output power is the power corresponding to the highest gear of the gas device, and the purpose is to make the water supply temperature of the hydraulic module rise as soon as possible until it is higher than the target refrigerant temperature of the terminal device.
[0157] In addition, when the water supply temperature of the hydraulic module is higher than the target refrigerant temperature of the terminal device, the gas device does not need to be used for heat compensation, at which time the operation of the gas device can be closed to save gas cost.
[0158] In another possible embodiment, in addition to determining whether the gas device needs to be started according to the water supply temperature of the hydraulic module and the target temperature of the terminal device, a temperature sensor can be arranged between the hydraulic module and the terminal device to detect the actual water temperature TW1B at a position closer to the terminal device. Specifically, the size relationship between TW1B and the target temperature TWs of the terminal device can be determined, and when TW1B≤TWs, the operation state of the gas device is set to be started, and when TW1B>TWs, the operation state of the gas device is set to be closed. Different from the foregoing embodiment, TW1B is closer to the actual temperature of the terminal device than TW1, so it can better reflect the temperature condition of the terminal device without considering heat loss.
[0159] For ease of understanding, with reference to the foregoing embodiments of the application, the foregoing embodiments of the application are described in detail below. Figure 5 A possible control method of the environmental regulation system can include the following steps: first, the environmental regulation system is powered on, and the components such as the heat pump indoor unit, the hydraulic module, and the gas device are started according to the control method. Figure 1The environment adjusting system and the heat pump indoor unit are connected in a communication mode, and the communication connection is normal; the intelligent heat supplement function of the environment adjusting system is displayed, and the heat pump indoor unit and / or the terminal equipment in the target area are turned on; when the communication connection is abnormal, the related function is not displayed or is grayed out; the intelligent heat supplement function of the environment adjusting system is turned on, and the running state of the heat pump indoor unit and the terminal equipment in the target area is recorded; the △T=T1-Ts is calculated; when the △T is greater than or equal to 1 DEG C, the target area is determined to be a temperature reaching area, the current running state of the heat pump indoor unit is kept, and the running state of the heat pump indoor unit and the terminal equipment is judged and selected according to the running state of the heat pump indoor unit and the terminal equipment; when only the terminal equipment is in the running state, the heat supply of the terminal equipment is controlled according to the target water temperature and the outdoor environment temperature; when the heat pump indoor unit and the terminal equipment are in the running state, when the outdoor environment temperature T2 is less than a, only the running state of the terminal equipment is kept, and when the outdoor environment temperature T2 is greater than b, only the running state of the heat pump indoor unit is kept; when only the heat pump indoor unit is in the running state, the current state is kept unchanged. When the 1 DEG C is greater than the △T and the 0 DEG C, the target area is determined to be a near temperature area, the running state of the heat pump indoor unit is kept, the heating function of the terminal equipment is turned on, the gas wall-hanging stove heating is turned on, and the high water temperature output is set; when a preset time length or the △T is greater than or equal to 1 DEG C, the gas wall-hanging stove is turned off, and the running state of the heat pump indoor unit and the terminal equipment is restored according to the running state of the heat pump indoor unit and the terminal equipment before entering the intelligent heat supplement. When the △T is less than -1 DEG C, the target area is determined to be a far temperature area, and the heating of the multi-connected indoor unit and the terminal equipment is kept; when TW1 is less than or equal to TWs+1 or TW1B is less than or equal to TWs, the gas wall-hanging stove is turned on and the high water temperature output is set, otherwise, the gas wall-hanging stove is turned off.
