[0092] In the process of the heat pump system running in the heating mode, the refrigerant discharged by the compressor flows through the second heat exchanger, the throttling device and the first heat exchanger in turn and then returns to the compressor, the second heat exchanger is in a heat releasing state and the first heat exchanger is in a heat absorbing state. In this process, the carrier refrigerant in the carrier refrigerant circulation system circulates, and when the carrier refrigerant flows through the heat exchange module, it can absorb the heat released by the second heat exchanger and then flow to the indoor terminal equipment; all indoor terminal equipment or indoor terminal equipment in the indoor space with heating demand is opened, and the opened indoor terminal equipment is in a heating state to release heat to the space where it is located; and the first heat exchanger is in the outdoor environment, and when the outdoor environment temperature is too low, the first heat exchanger will appear frost phenomenon.

[0093] In the process of step S10, the convection heat exchange device in the indoor space with heating demand can be opened. In the process of opening the convection heat exchange device, the corresponding sub-regulation module is opened and the indoor fan in the convection heat exchange device is opened, and the carrier refrigerant can circulate between the convection heat exchange device and the heat exchange module; in the process of closing the convection heat exchange device, the corresponding sub-regulation module is closed and the indoor fan in the convection heat exchange device is closed. Wherein, the number of convection heat exchange devices is more than one, when different convection heat exchange devices are arranged in different indoor spaces, the convection heat exchange device in the indoor space with heating demand is opened, and the convection heat exchange device in the indoor space without heating demand can be closed.

[0094] The gas device can be turned on or turned off during the heating process of the heat pump system. The gas device can be turned on in response to a user instruction, can be turned on when the operating state of the heat pump system and / or the environmental parameters and / or the load-carrying agent in the load-carrying agent circulation system meet the heat supplement condition, and the like.

[0095] In step S20, when the heat pump system operates to meet the defrosting condition, the heat pump system is controlled to operate in a defrosting mode, the gas device is controlled to be turned on to supplement heat for the indoor terminal device, and the convection heat exchange device is controlled to be maintained in an open state.

[0096] In the defrosting mode, the second heat exchanger is in a heat absorption state and the first heat exchanger is in a heat release state.

[0097] The defrosting condition specifically refers to a condition required to be met by the operating parameters (such as the temperature of the first heat exchanger, the operating time of the heat pump system, and the like) of the heat pump system itself and / or the environmental parameters (such as the outdoor environmental temperature, and the like) of the environment in which the environmental regulation system is located when the first heat exchanger needs to be defrosted. For example, the defrosting condition includes that the temperature of the first heat exchanger is lower than a first temperature threshold and / or the outdoor environmental temperature is lower than a second temperature threshold, and the like.

[0098] Here, turning on the gas device includes maintaining the gas device in an open state or switching the gas device from a closed state to an open state. In order to enable the gas device to maintain the open state to supplement heat for the indoor terminal device, the heating power of the gas device needs to be increased at this time. The heating control parameter when the gas device is turned on can be a fixed parameter set in advance, for example, the gas device is controlled to operate according to the maximum heating power or the maximum water outlet temperature; or the heating control parameter when the gas device is turned on can also be determined according to the actual operating state of the load-carrying agent circulation system and / or the environmental state, and the like. When the gas device is maintained in the open state, the heating amount of the gas device can be controlled to be increased.

[0099] When the defrosting mode is started during the operation of the heat pump system in the heating mode, the reversing component is switched from the first operating state to the second operating state. During the operation of the heat pump system in the defrosting mode, the refrigerant flowing out of the compressor flows through the first heat exchanger, the throttling device, and the second heat exchanger in sequence and then returns to the compressor, the first heat exchanger releases heat to melt ice and frost, and the second heat exchanger can absorb heat from the load-carrying agent circulation system for defrosting and ensuring normal heat exchange circulation of the system.

[0100] The gas equipment is opened first, and then the heat pump system is switched to the defrosting mode; or, the heat pump system is switched to the defrosting mode first, and then the gas equipment is opened; or, the heat pump system is switched to the defrosting mode and the gas equipment is opened at the same time. In this embodiment, in order to further reduce the indoor space fluctuation, when the heat pump system meets the defrosting condition, the gas equipment can be opened first, the temperature change state of the heat exchange module is detected, and when the temperature rising amplitude of the heat exchange module reaches a preset amplitude, the heat pump system is switched to the defrosting mode.

[0101] Here, the control of maintaining the opening of the convection heat exchange device means that the convection heat exchange device in the opening state is maintained in the opening state, and the convection heat exchange device in the closed state is maintained in the closed state.

[0102] The embodiment provides a control method of an environment adjusting system. When the heat pump system needs to defrost the first heat exchanger during the heating mode, the gas equipment is opened to heat the cold carrier in the cold carrier circulating system during the defrosting process of the heat pump system, heat is supplied to the indoor terminal equipment, the convection heat exchange device is maintained in the opening state, the indoor terminal equipment can maintain the heat delivery to the indoor environment during the defrosting process of the heat pump system, indoor temperature fluctuation during the defrosting process of the heat pump system is effectively reduced, and indoor comfort is improved.

[0107] In an implementation manner, the target rotating speed of the fan is determined according to the coil temperature, different coil temperatures correspond to different target rotating speeds, and the fan is controlled to operate at the target rotating speed. In another implementation manner, the rotating speed adjustment parameter of the fan is determined according to the coil temperature, and the current rotating speed of the fan is adjusted according to the rotating speed adjustment parameter.

[0108] When the number of the opened convection heat exchange devices is more than one, the fans in different convection heat exchange devices are controlled according to the respective coil temperatures.

[0109] In the embodiment, steps S21 to S22 are executed cyclically until the defrosting exit condition of the heat pump system is met.

[0110] In the embodiment, the coil temperature of the heat exchanger is adapted to regulate the rotation speed of the fan during the defrosting process of the heat pump system, which is conducive to improving the accuracy of regulating the heat exchange of the convection heat exchange device and avoiding excessively low or high outlet air temperature, so as to reduce the indoor temperature fluctuation while ensuring the defrosting effect of the heat pump system.

[0111] Further, in the embodiment, the step of controlling the fan operation according to the coil temperature comprises:

[0112] When the coil temperature is less than or equal to a first preset temperature, the rotation speed of the fan is reduced, or the fan is stopped; when the coil temperature is greater than the first preset temperature, the current rotation speed of the fan is maintained.

[0113] Therefore, the cold air blowing of the convection heat exchange device is effectively avoided, and the indoor temperature comfort during the defrosting process is further improved. In addition, the heating capacity is not too large, so as to ensure the defrosting effect of the heat pump system.

[0114] Further, in the embodiment, the step of controlling the fan operation according to the coil temperature comprises:

[0124] In a feasible implementation manner of the embodiment, with reference to Figure 5 , after the step of controlling the gas device to be turned on to supplement heat for the indoor terminal device, the embodiment further comprises:

[0125] Step S201, controlling the gas device to operate according to a target outlet temperature of the gas device;

[0126] The target outlet temperature herein is specifically a target temperature required to be reached by the secondary refrigerant flowing out of the secondary refrigerant flow path in the gas device. Optionally, the target outlet temperature is in a range of [35℃, 80℃], for example, the target outlet temperature can be 60℃.

[0127] The reference temperature is specifically 50% of the maximum outlet temperature of the gas device. Here, the target outlet temperature being greater than the reference temperature indicates that the gas device outputs high heating capacity in the defrosting mode. The target outlet temperature can be a pre-set fixed temperature, for example, the target outlet temperature can be the maximum outlet temperature; or, the target outlet temperature can also be a temperature determined according to actual operation of the environment regulation system, for example, the target outlet temperature herein can be determined according to the temperature of the first heat exchanger and / or the temperature of the second heat exchanger and / or the temperature difference between the set temperature and the environment temperature of the indoor space where the currently opened indoor terminal device is located and / or the outdoor environment temperature, etc.

[0128] In this embodiment, the heating capacity of the gas device can be increased, maintained or reduced according to the actual outlet temperature and the target outlet temperature of the gas device. Optionally, the heating capacity adjustment parameter of the gas device can be determined according to the actual outlet temperature and the target outlet temperature, and the gas device is controlled to operate according to the heating capacity adjustment parameter.

[0134] In step S203, the gas device is controlled to operate according to the temperature of the secondary refrigerant and the target temperature of the secondary refrigerant.

[0135] The target temperature of the secondary refrigerant is a target temperature of the secondary refrigerant in the secondary refrigerant circulating system during the starting of the gas device. The target temperature of the secondary refrigerant is lower than the target supply temperature. The target temperature of the secondary refrigerant can be different when the detection position corresponding to the temperature of the secondary refrigerant is different. The target temperature of the secondary refrigerant can be a fixed temperature set in advance or a temperature determined according to the actual operation of the environmental regulation system.

[0136] The heating amount of the gas device is increased, maintained or decreased according to the size relationship or the quantitative relationship value (such as the difference or the ratio) between the temperature of the secondary refrigerant and the target temperature of the secondary refrigerant.

[0137] In the embodiment, when the temperature of the secondary refrigerant is lower than the target temperature of the secondary refrigerant, the heating amount of the gas device is increased; and when the temperature of the secondary refrigerant is greater than or equal to the target temperature of the secondary refrigerant, the heating amount of the gas device is decreased or maintained.

[0146] In the embodiment, the characteristic temperature is the supply liquid temperature of the fluid regulation module.

[0147] The defrosting exit condition specifically refers to a condition required to be met by the operating parameters of the heat pump system itself and / or the environmental parameters of the environment where the first heat exchanger is located when the defrosting of the first heat exchanger is completed. The temperature of the first heat exchanger is greater than or equal to a second temperature threshold, and the second temperature threshold is greater than the first temperature threshold.
