[0030] Combination Figure 1 As shown, the embodiment of the present disclosure provides a heat pump system, including: an outdoor system 100 and an indoor system 200. The indoor system 200 includes a first heat exchange branch 201, provided with a ceiling capillary 40, and the ceiling capillary 40 is installed in the upper part of the room; a second heat exchange branch 202, connected in parallel with the first heat exchange branch 201, provided with an air conditioning heat exchanger 50, and the air conditioning heat exchanger 50 is installed in the middle of the room; a third heat exchange branch 203, connected in parallel with the first heat exchange branch 201 and the second heat exchange branch 202, provided with a floor heating capillary 60, and the floor heating capillary 60 is installed in the lower part of the room.

[0031] The heat pump system provided by the embodiment of the present disclosure is used, and ceiling capillary tubes 40, air conditioning heat exchangers 50, and floor heating capillary tubes 60 are respectively installed at different heights indoors, and the heat exchange branches where the three are located are arranged in parallel. As a result, the heat pump system can select the appropriate indoor heat exchange branch to be turned on under different operation processes, so as to adapt to the actual comfort needs of users, and can take into account both rapid indoor temperature adjustment and uniform indoor temperature control, which is conducive to better ensuring the user's comfortable experience.

[0032] Optionally, the first heat exchange branch 201 is further provided with a first ceiling control valve 41 and a second ceiling control valve 42. The first ceiling control valve 41 and the second ceiling control valve 42 are respectively arranged on both sides of the ceiling capillary 40.

[0033] Optionally, the second heat exchange branch 202 is further provided with a first air conditioning control valve 51 and a second air conditioning control valve 52. The first air conditioning control valve 51 and the second air conditioning control valve 52 are respectively arranged on both sides of the air conditioning heat exchanger 50.

In this way, the first floor heating control valve 61 and the second floor heating control valve 62 can be used to control the conduction or isolation of the third heat exchange branch 203, thereby realizing the switching of the working state of the floor heating capillary tube 60.

[0035] Optionally, the outdoor system 100 includes a compressor 10, a four-way valve 20 and an outdoor heat exchanger 30 that are connected in sequence. In this way, the outdoor system 100 and the indoor system 200 can be connected through a refrigerant pipeline to form a refrigerant circulation loop, and the specific flow direction of the refrigerant can be switched through the four-way valve 20 to reasonably adjust the operation mode of the heat pump system.

[0036] Optionally, the heat pump system further includes an outdoor control valve 31. The outdoor control valve 31 is disposed between the outdoor heat exchanger 30 and the indoor system 200. In this way, the working state of the outdoor heat exchanger 30 can be controlled by adjusting the opening of the outdoor control valve 31 to ensure reliable operation of the heat pump system.

[0037] Optionally, the heat pump system further includes a first stop valve 71 and a second stop valve 72. The first stop valve 71 and the second stop valve 72 are both arranged between the outdoor system 100 and the indoor system 200. In this way, the liquid pipe and the gas pipe of the heat pump system can be completely closed or opened by the first stop valve 71 and the second stop valve 72, which is conducive to ensuring the reliable operation of the heat pump system.

[0038] Optionally, the heat pump system further includes a device 300 for adjusting the heat pump system. The device 300 for adjusting the heat pump system is electrically connected to the first heat exchange branch 201, the second heat exchange branch 202, and the third heat exchange branch 203, respectively. In this way, the embodiment of the present disclosure can execute a corresponding control method through the device 300 to reasonably adjust the operation of the heat pump system.

[0039] Based on the above heat pump system, combined with Figure 2 As shown, the embodiment of the present disclosure provides a method for adjusting a heat pump system, comprising:

[0040] S101, the processor obtains the operation mode of the heat pump system and the real-time indoor temperature.

[0041] S102: When the real-time indoor temperature does not meet the temperature reaching condition, the processor controls the second heat exchange branch to be turned on.

[0042] S103, when the real-time indoor temperature meets the temperature reaching condition, the processor controls the first heat exchange branch or the third heat exchange branch to be turned on and controls the second heat exchange branch to be turned off according to the operation mode of the heat pump system.

[0043] The method for adjusting the heat pump system provided by the embodiment of the present disclosure is adopted, and ceiling capillaries, air conditioning heat exchangers, and floor heating capillaries are respectively installed at different heights in the room. Then, the actual comfort needs of the user can be judged by obtaining the operation mode of the heat pump system, and the current operation process can be grasped by obtaining the real-time temperature in the room, so that the operation of the heat pump system can be adjusted more reasonably. Specifically, when the real-time temperature in the room does not meet the temperature reaching condition, it indicates that the heat pump system is in the early stage of operation. The embodiment of the present disclosure can control the conduction of the second heat exchange branch to use the air conditioning heat exchanger for convective heat exchange, which is conducive to rapid indoor temperature adjustment, so as to meet the comfort needs of the user in a timely manner. When the real-time temperature in the room meets the temperature reaching condition, it indicates that the heat pump system is in the late stage of operation. The embodiment of the present disclosure can control the isolation of the second heat exchange branch to avoid the discomfort caused by the air conditioning heat exchanger blowing directly to the user. In combination with the operation mode of the heat pump system, the first heat exchange branch or the third heat exchange branch is selected to be turned on, so as to accurately adapt to the user's comfort needs, so as to reasonably use the ceiling capillary or the floor heating capillary to radiate heat, which is conducive to achieving uniform indoor temperature control, so as to better fit the user's actual comfort feeling. Therefore, the embodiment of the present disclosure can select the appropriate indoor heat exchange branch to be turned on under different operation processes, so as to adapt to the user's actual comfort needs, and can take into account both indoor rapid temperature adjustment and indoor uniform temperature control, which is conducive to better ensuring the user's comfortable experience.

[0044] Optionally, the processor controls the first heat exchange branch or the third heat exchange branch to be turned on according to the operating mode of the heat pump system, including: when the heat pump system operates in a cooling mode, the processor controls the first heat exchange branch to be turned on; or, when the heat pump system operates in a heating mode, the processor controls the third heat exchange branch to be turned on.

[0045] In this way, when the heat pump system is running in cooling mode, the user expects the indoor temperature to decrease. After the real-time temperature in the room meets the temperature reaching condition, the disclosed embodiment can control the first heat exchange branch to be turned on, thereby controlling the ceiling capillary radiation cooling, bringing the user a comfortable feeling of cool head. At this time, the cold air with relatively large density will gradually settle down from the upper part of the room, which will help to achieve uniform temperature control in the room, so as to better ensure the user's comfortable experience. When the heat pump system is running in heating mode, the user expects the indoor temperature to increase. After the real-time temperature in the room meets the temperature reaching condition, the disclosed embodiment can control the third heat exchange branch to be turned on, thereby controlling the floor heating capillary radiation heating, bringing the user a comfortable feeling of warm feet. At this time, the hot air with relatively small density will gradually rise from the lower part of the room, thereby helping to achieve uniform temperature control in the room, so as to better ensure the user's comfortable experience.

[0046] Optionally, the processor determines that the real-time indoor temperature meets the temperature reaching condition in the following manner: the processor detects that the absolute value of the difference between the real-time indoor temperature and the target temperature is less than or equal to a preset temperature difference.

[0047] In this way, when the heat pump system is running for cooling, the indoor temperature gradually decreases. When the difference between the indoor real-time temperature and the target temperature is less than or equal to the preset temperature difference, it indicates that the indoor real-time temperature is close to the target temperature set by the user, so it can be judged that the temperature reaching condition is currently met. Alternatively, when the heat pump system is running for heating, the indoor temperature gradually rises. When the difference between the indoor target temperature and the real-time temperature is less than or equal to the preset temperature difference, it indicates that the indoor real-time temperature is close to the target temperature set by the user, so it can be judged that the temperature reaching condition is currently met. At this time, the heat pump system can further adjust the indoor heat exchange branch to be turned on, so as to select a more suitable heat exchange position indoors, which is conducive to better maintaining the indoor temperature stability and improving the uniformity of the indoor temperature.

[0048] Optionally, the preset temperature difference can be set in combination with the size of the indoor space. Preferably, the preset temperature difference can be set to 3°C to better ensure the user's comfort. The preset temperature difference can also be adjusted according to the actual needs of the user, and can also be set to any other reasonable value such as 1°C or 5°C.

[0049] Based on the above heat pump system, combined with Figure 3 As shown, the embodiment of the present disclosure provides another method for adjusting a heat pump system, comprising:

[0050] S201, the processor obtains the operation mode of the heat pump system and the real-time indoor temperature.

[0051] S202: When the real-time indoor temperature does not meet the temperature reaching condition, the processor controls the second heat exchange branch to be turned on.

[0052] S203, the processor controls the on / off state of the first heat exchange branch or the third heat exchange branch according to the indoor user situation.

[0053] S204, when the real-time indoor temperature meets the temperature reaching condition, the processor controls the first heat exchange branch or the third heat exchange branch to be turned on and controls the second heat exchange branch to be turned off according to the operation mode of the heat pump system.

[0054] By using the method for adjusting the heat pump system provided by the embodiment of the present disclosure, when the real-time indoor temperature does not meet the temperature reaching condition, the embodiment of the present disclosure can control the conduction of the second heat exchange branch to use the air conditioner heat exchanger for convective heat exchange, which is conducive to achieving rapid indoor temperature adjustment, thereby timely meeting the user's comfort needs. At the same time, the embodiment of the present disclosure also detects the indoor user situation, and controls the on-off state of the first heat exchange branch or the third heat exchange branch accordingly, so that the indoor temperature uniformity can be taken into account while the indoor temperature is rapidly adjusted, which is conducive to better ensuring the user's comfortable experience.

[0055] Optionally, the processor controls the on / off state of the first heat exchange branch or the third heat exchange branch according to the user situation in the room, including: when there is no user in the room, the processor controls the first heat exchange branch and the third heat exchange branch to be isolated; or, when there is a user in the room, the processor controls the first heat exchange branch or the third heat exchange branch to be turned on with a small opening.

[0056] In this way, when there is no user indoors, the disclosed embodiment can control the conduction of the second heat exchange branch, and control the isolation of the first heat exchange branch and the third heat exchange branch, at which time all the refrigerant flowing out of the outdoor system flows into the second heat exchange branch. Thus, the heat exchange effect of the air-conditioning heat exchanger can be maximized to give priority to the indoor temperature adjustment efficiency, and significantly shorten the temperature adjustment time for the indoor temperature to reach the target temperature. When there is a user indoors, the disclosed embodiment can control the conduction of the second heat exchange branch, and control the first heat exchange branch or the third heat exchange branch to be conducted with a small opening, at which time most of the refrigerant flowing out of the outdoor system flows into the second heat exchange branch, and a small part of the refrigerant flows into the first heat exchange branch or the third heat exchange branch. Therefore, while ensuring the heat exchange effect of the air-conditioning heat exchanger to achieve rapid indoor temperature adjustment, the disclosed embodiment can also use a small amount of refrigerant to pre-cool the ceiling capillary or pre-heat the floor heating capillary. On the one hand, the uniformity of the indoor temperature can be improved in the early stage of operation, thereby improving the immediate comfort of indoor users. On the other hand, it can also enable the ceiling capillaries or floor heating capillaries to enter the working state in advance, which is beneficial to ensure the heat exchange effect of the system in the later stage of operation, avoid large fluctuations in indoor temperature causing discomfort to users, and thus improve the user's overall comfort experience.

[0057] Optionally, the processor controls the first heat exchange branch or the third heat exchange branch to be turned on with a small opening, including: when the heat pump system operates in cooling mode, the processor controls the first heat exchange branch to be turned on with a small opening; or, when the heat pump system operates in heating mode, the processor controls the third heat exchange branch to be turned on with a small opening.

[0058] In this way, the disclosed embodiment can be combined with the operation mode of the heat pump system to coordinate the control of the first heat exchange branch or the third heat exchange branch to be turned on with a small opening, so that a small amount of refrigerant can be used to pre-cool the ceiling capillary tube during cooling operation, or a small amount of refrigerant can be used to pre-heat the floor heating capillary tube during heating operation. On the one hand, the uniformity of indoor temperature can be improved in the early stage of operation, thereby improving the immediate comfort of indoor users. On the other hand, the ceiling capillary tube or the floor heating capillary tube can also be put into working state in advance, which is conducive to ensuring the heat exchange effect of the system in the later stage of operation, avoiding large fluctuations in indoor temperature causing discomfort to users, thereby improving the overall comfort experience of users.

[0059] Optionally, when the heat pump system is running in cooling mode, the opening of the first heat exchange branch is negatively correlated with the difference between the real-time temperature in the room and the target temperature. That is, during the cooling operation of the heat pump system, as the difference between the real-time temperature in the room and the target temperature becomes smaller and smaller, it indicates that the real-time temperature in the room is getting closer to the target temperature set by the user. At this time, the first heat exchange branch can be appropriately controlled to be turned on with a relatively large opening, for example, by increasing the opening of the first ceiling control valve, thereby increasing the refrigerant flow through the first heat exchange branch. At this time, the heat pump system gradually increases the cooling weight of the ceiling radiation, which is conducive to achieving a progressive cooling effect to better ensure the user's comfort experience.

[0060] Optionally, when the heat pump system is running in heating mode, the opening of the third heat exchange branch is negatively correlated with the difference between the indoor target temperature and the real-time temperature. That is, during the heating operation of the heat pump system, as the difference between the indoor target temperature and the real-time temperature becomes smaller and smaller, it indicates that the indoor real-time temperature is getting closer and closer to the target temperature set by the user. At this time, the third heat exchange branch can be appropriately controlled to be turned on with a relatively large opening, for example, increasing the opening of the second floor heating control valve, thereby increasing the refrigerant flow through the third heat exchange branch. At this time, the heat pump system gradually increases the heating proportion of floor heating radiation, which is conducive to achieving a progressive foot-warming effect to better ensure the user's comfort experience.

[0061] Based on the above heat pump system, combined with Figure 4 As shown, the embodiment of the present disclosure provides another method for adjusting a heat pump system, comprising:

[0062] S301, the processor obtains the operation mode of the heat pump system and the real-time indoor temperature.

[0063] S302: When the real-time indoor temperature does not meet the temperature reaching condition, the processor controls the second heat exchange branch to be turned on.

[0064] S303, when the real-time indoor temperature meets the temperature reaching condition, the processor controls the first heat exchange branch or the third heat exchange branch to be turned on and controls the second heat exchange branch to be turned off according to the operation mode of the heat pump system. Or,

[0065] S304, when the heat pump system operates in a dehumidification mode, the processor controls the second heat exchange branch to be turned on, and controls the first heat exchange branch and the third heat exchange branch to be turned off.

[0066] By using the method for adjusting the heat pump system provided by the embodiment of the present disclosure, when the heat pump system is running in the dehumidification mode, the embodiment of the present disclosure controls the second heat exchange branch to be turned on, so as to use the air conditioning heat exchanger to complete the dehumidification work, thereby accurately regulating the indoor environmental humidity to comprehensively ensure the user's comfortable experience. At the same time, the embodiment of the present disclosure controls the first heat exchange branch to be isolated from the third heat exchange branch, so as to avoid condensation in the ceiling capillary and the floor heating capillary, which is conducive to preventing the ceiling or floor from being damaged due to condensation, and improving the safety of the heat pump system.

[0067] Based on the above heat pump system, combined with Figure 5 As shown, the embodiment of the present disclosure provides another method for adjusting a heat pump system, comprising:

[0068] S401, the processor obtains the operation mode of the heat pump system and the real-time indoor temperature.

[0069] S402: When the real-time indoor temperature does not meet the temperature reaching condition, the processor controls the second heat exchange branch to be turned on.

[0070] S403, when the real-time indoor temperature meets the temperature reaching condition, the processor controls the first heat exchange branch or the third heat exchange branch to be turned on and controls the second heat exchange branch to be turned off according to the operation mode of the heat pump system.

[0071] S404: When the heat pump system meets the refrigerant excess condition, the processor controls the third heat exchange branch or the first heat exchange branch to store part of the refrigerant according to the operation mode of the heat pump system.

[0072] The method for adjusting the heat pump system provided by the embodiment of the present disclosure is adopted, and ceiling capillaries, air conditioning heat exchangers and floor heating capillaries are respectively installed at different heights in the room. The heat pump system can select the appropriate indoor heat exchange branch to be turned on under different operating processes, so as to adapt to the actual comfort needs of users, and can take into account both rapid indoor temperature adjustment and uniform indoor temperature control, which is conducive to better ensuring the user's comfortable experience. At the same time. The embodiment of the present disclosure can also monitor the refrigerant filling status of the heat pump system. If it is determined that the refrigerant excess condition is currently met, the idle indoor heat exchange branch can be used to store excess refrigerant, which is conducive to improving the working energy efficiency of the heat pump system, so as to better exert the working capacity of the heat pump system.

[0073] Optionally, the processor controls the third heat exchange branch or the first heat exchange branch to store part of the refrigerant according to the operating mode of the heat pump system, including: when the heat pump system operates in cooling mode, the processor controls the third heat exchange branch to store part of the refrigerant; or, when the heat pump system operates in heating mode, the processor controls the first heat exchange branch to store part of the refrigerant.

[0074] In this way, when the heat pump system operates in cooling mode, the second heat exchange branch can be turned on in the initial stage of cooling to use the air conditioner heat exchanger for convection cooling, and the first heat exchange branch can be turned on in the later stage of cooling to use the ceiling capillary tube radiation cooling. At this time, the floor heating capillary tube is not put into use during the entire cooling process due to the poor actual cooling effect. Therefore, the third heat exchange branch can be used as an idle heat exchange branch to store part of the refrigerant, so that it can play its liquid storage role when the refrigerant is overfilled, which is conducive to properly improving the working energy efficiency of the heat pump system and better exerting the cooling capacity of the heat pump system. Similarly, when the heat pump system operates in heating mode, the second heat exchange branch can be turned on in the initial stage of heating to use the air conditioner heat exchanger for convection heating, and the third heat exchange branch can be turned on in the later stage of heating to use the floor heating capillary tube radiation heating. At this time, the ceiling capillary tube is not put into use during the entire heating process due to poor actual heating effect. Therefore, the first heat exchange branch can be used as an idle heat exchange branch to store part of the refrigerant, so that it can play its liquid storage role when the refrigerant is excessive, which is conducive to appropriately improving the working energy efficiency of the heat pump system and better exerting the heating capacity of the heat pump system.
