Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a temperature control system. Background Technology

[0002] Existing temperature control systems typically have only one evaporation temperature and one condensation temperature, making their functions relatively simple. To add more functions, it is usually necessary to add an additional set of equipment with corresponding functions, which results in a complex structure and poor applicability of existing temperature control systems. Summary of the Invention

[0003] The main objective of this invention is to propose a temperature regulation system that is simple in structure and can simultaneously achieve multiple functions.

[0004] To achieve the above objectives, the present invention proposes a temperature control system, which includes a compressor, a switching device, an indoor heat exchange device, an outdoor heat exchange device, and a hot water heat exchanger.

[0005] The hot water heat exchanger is used to install in the water heater;

[0006] The temperature control system has at least a first working mode. In the first working mode, the switching device controls the refrigerant discharged by the compressor to be distributed to the hot water heat exchanger and the outdoor heat exchanger for condensation and heat release, and then flows through the indoor heat exchanger for evaporation and heat absorption before returning to the compressor.

[0007] In one embodiment, the compressor has a first exhaust port and a second exhaust port respectively connected to the switching device; the first operating mode includes a first hot water production mode, in which the switching device controls the refrigerant discharged from the first exhaust port of the compressor to flow through the outdoor heat exchange device to condense and release heat, and the refrigerant discharged from the second exhaust port to flow through the hot water heat exchanger to condense and release heat, and then flow through the indoor heat exchange device to evaporate and absorb heat before returning to the compressor.

[0008] And / or, the first operating mode includes a second hot water production mode, in which the switching device controls the refrigerant discharged from the first and second exhaust ports of the compressor to flow through the hot water heat exchanger to condense and release heat, and then flow through the indoor heat exchange device to evaporate and absorb heat before returning to the compressor.

[0009] In one embodiment, the first operating mode further includes a first indoor cooling mode. In the first indoor cooling mode, the switching device controls the refrigerant discharged from the first and second exhaust ports of the compressor to flow through the outdoor heat exchange device to condense and release heat, and then flow through the indoor heat exchange device to evaporate and absorb heat before returning to the compressor.

[0010] In one embodiment, the indoor heat exchange device has a first indoor heat exchange channel and a second indoor heat exchange channel. The compressor is connected in sequence with the outdoor heat exchange device and the first indoor heat exchange channel via the switching device to form a first circulation loop. The compressor is connected in sequence with the hot water heat exchanger and the second indoor heat exchange channel via the switching device to form a second circulation loop.

[0011] In one embodiment, the switching device is used to control the refrigerant in the first circulation loop to flow through the outdoor heat exchanger and condense and release heat, and to control the refrigerant in the second circulation loop to flow through the hot water heat exchanger and condense and release heat, so as to form a first hot water production mode. In the first hot water production mode, the refrigerant pressure flowing into the hot water heat exchanger is greater than the refrigerant pressure flowing into the outdoor heat exchanger.

[0012] In one embodiment, the indoor heat exchange device has a first air duct, and in the first hot water production mode, the second indoor heat exchange channel is located downstream of the first indoor heat exchange channel along the air outlet direction of the first air duct.

[0015] In one embodiment, the switching device further includes a second connecting pipe, a second valve body, and a third valve body. The switching device is connected to the outdoor heat exchange device via a third pipeline, and the switching device is connected to the hot water heat exchanger via a fourth pipeline. One end of the second connecting pipe is connected to the third pipeline, and the other end of the second connecting pipe is connected to the fourth pipeline or the hot water heat exchanger. The second valve body is disposed on the second connecting pipe, and the third valve body is disposed on the third pipeline connecting one end of the second connecting pipe to the outdoor heat exchange device.

[0016] In one embodiment, the compressor has a first exhaust port and a second exhaust port respectively connected to the switching device; the first operating mode includes a first hot water production mode, in which the first valve body is closed, the second valve body is closed, the third valve body is open, and the switching device controls the refrigerant discharged from the first exhaust port of the compressor to flow along the first circulation loop, and the refrigerant discharged from the second exhaust port to flow along the second circulation loop.

[0017] And / or, the first working mode includes a second hot water production mode. In the second hot water production mode, the first valve body is open, the second valve body is open, and the third valve body is closed. The switching device controls the refrigerant discharged from the first and second exhaust ports of the compressor to flow through the hot water heat exchanger to condense and release heat, and then be diverted to the first indoor heat exchange channel and the second indoor heat exchange channel to evaporate and absorb heat.

[0018] In one embodiment, the hot water heat exchanger has a first hot water heat exchange channel, and the other end of the second connecting pipe is connected to the fourth pipeline. The first working mode includes a second hot water production mode. In the second hot water production mode, the switching device controls the refrigerant discharged from the compressor to converge in the fourth pipeline and flow into the first hot water heat exchange channel to condense and release heat.

[0019] Alternatively, the hot water heat exchanger has a first hot water heat exchange channel and a second hot water heat exchange channel that are independent of each other and spaced apart. One of the first hot water heat exchange channel and the second hot water heat exchange channel is connected to the other end of the second connecting pipe, and the other is connected to the fourth pipeline.

[0020] In one embodiment, the switching device further includes a fourth valve body, the other end of the second connecting pipe is connected to the fourth pipeline, and the fourth valve body is disposed on the fourth pipeline connecting the other end of the second connecting pipe to the hot water heat exchanger;

[0021] The fourth valve body opens in either the first hot water production mode or the second hot water production mode.

[0022] In one embodiment, the first operating mode includes a first indoor cooling mode. In the first indoor cooling mode, the first valve body is open, the second valve body is open, the third valve body is open, and the fourth valve body is closed. The switching device controls the refrigerant discharged from the first and second exhaust ports of the compressor to flow through the outdoor heat exchange device to condense and release heat, and then divert it to the first indoor heat exchange channel and the second indoor heat exchange channel to evaporate and absorb heat.

[0023] In one embodiment, the indoor heat exchange device includes a first heat exchange tube and a second heat exchange tube, the first heat exchange tube having a first indoor heat exchange channel and the second heat exchange tube having a second indoor heat exchange channel; the first heat exchange tube and the second heat exchange tube are independent of each other and are spaced apart.

[0024] Alternatively, one of the first heat exchange tube and the second heat exchange tube may be at least partially disposed in the other, and a flow gap for refrigerant to pass through is provided between the first heat exchange tube and the second heat exchange tube.

[0025] In one embodiment, the first indoor heat exchange channel and the second indoor heat exchange channel are disposed in the same housing.

[0026] In one embodiment, the compressor has a first exhaust port, a second exhaust port, and an intake port, wherein the first exhaust port and the intake port are connected to a first circulation loop, and the second exhaust port and the intake port are connected to a second circulation loop.

[0027] In one embodiment, the compressor is a dual-cylinder, dual-suction, dual-exhaust compressor, and the intake port includes a first sub-intake port and a second sub-intake port. The first sub-intake port is connected to the first circulation loop, and the second sub-intake port is connected to the second circulation loop.

[0028] In one embodiment, the switching device includes a first reversing valve and a second reversing valve. The first reversing valve is connected to the first circulation loop to change the refrigerant flow direction in the first circulation loop; the second reversing valve is connected to the second circulation loop to change the refrigerant flow direction in the second circulation loop.

[0029] In one embodiment, the switching device includes a first throttling element and a second throttling element. The first throttling element is disposed in the first circulation loop and located between the outdoor heat exchange device and the first indoor heat exchange channel. The second throttling element is disposed in the second circulation loop and located between the hot water heat exchanger and the second indoor heat exchange channel.

[0030] The temperature control system of the present invention includes a compressor, a switching device, an indoor heat exchanger, an outdoor heat exchanger, and a hot water heat exchanger. The hot water heat exchanger is installed in a water heater for producing hot water. In the first operating mode, the switching device controls the distribution of refrigerant discharged from the compressor to the hot water heat exchanger and the outdoor heat exchanger for condensation and heat release. The refrigerant then flows through the indoor heat exchanger for evaporation and heat absorption before returning to the compressor. This arrangement ensures that the refrigerant discharged from the compressor can be distributed to the hot water heat exchanger for condensation and heat release to produce hot water, then flows through the indoor heat exchanger for evaporation and heat absorption to cool the room, and finally returns to the compressor, thus completing the refrigerant cycle. During the process, the temperature control system simultaneously achieves the functions of hot water production and indoor cooling, and its structure is simple. Alternatively, a switching device can control a portion of the refrigerant to be distributed to the hot water heat exchanger for condensation and heat release, producing hot water, while another portion is distributed to the outdoor heat exchanger for condensation and heat release. Then, the refrigerant flowing from both the hot water and outdoor heat exchangers flows into the indoor heat exchanger for evaporation and heat absorption, providing indoor cooling, and finally returns to the compressor. Thus, during the refrigerant circulation process, the temperature control system simultaneously achieves the functions of hot water production and indoor cooling, and the indoor environment can be cooled quickly. The temperature control system has a simple structure. Therefore, the temperature control system of this invention, by setting up a compressor, can simultaneously achieve the functions of hot water production and indoor cooling in the first working mode. Furthermore, the temperature control system has a simple structure and the compressor has high energy efficiency. This invention proposes a temperature control system with a simple structure that can simultaneously achieve multiple functions. Attached Figure Description

[0042] Existing temperature control systems typically have only one evaporation temperature and one condensation temperature, making their functions relatively simple. To add more functions, it is usually necessary to add an additional set of equipment with corresponding functions, which results in a complex structure and poor applicability of existing temperature control systems.

[0043] To address the aforementioned problems, this invention proposes a temperature regulation system that has a simple structure and can simultaneously perform multiple functions.

[0044] Please see Figures 1 to 4In one embodiment of the temperature regulation system 10 of the present invention, the temperature regulation system 10 includes a compressor 100, a switching device 200, an indoor heat exchange device 300, an outdoor heat exchange device 400, and a hot water heat exchanger 500; the hot water heat exchanger 500 is used to be installed in a water heater; the temperature regulation system 10 has at least a first working mode, in which the switching device 200 controls the refrigerant discharged by the compressor 100 to be distributed to the hot water heat exchanger 500 and the outdoor heat exchange device 400 for condensation and heat release, and then flows through the indoor heat exchange device 300 for evaporation and heat absorption before returning to the compressor 100.

[0045] It is understood that the indoor heat exchanger 300 has an indoor heat exchange channel through which the refrigerant flows for heat exchange. The number of indoor heat exchange channels can be one, two, or more, and is not limited here. The outdoor heat exchanger 400 has an outdoor heat exchange channel, and the number of outdoor heat exchange channels can be one, two, or more, and is not limited here. The indoor heat exchange channel and / or the outdoor heat exchange channel can be tubular, plate-like, or of other shapes, and is not limited here. The switching device 200 is used to control the flow of refrigerant discharged from the compressor 100. The specific structure of the switching device 200 will be described in detail later and will not be repeated here.

[0046] Furthermore, in the first operating mode, the switching device 200 controls the distribution of refrigerant discharged from the compressor 100 to the hot water heat exchanger 500 and the outdoor heat exchange device 400 for condensation and heat release. There are several ways the refrigerant can be distributed. For example, all the refrigerant discharged from the compressor 100 can be distributed to the hot water heat exchanger 500 for condensation and heat release, and then flow through the indoor heat exchange device 300 for evaporation and heat absorption. Another example is that a portion of the refrigerant discharged from the compressor 100 is distributed to the hot water heat exchanger 500 for condensation and heat release, while the other portion is distributed to the outdoor heat exchange device 400 for condensation and heat release, and then flow through the indoor heat exchange device 300 for evaporation and heat absorption. Yet another example is that all the refrigerant discharged from the compressor 100 can be distributed to the outdoor heat exchange device 400 for condensation and heat release, and then flow through the indoor heat exchange device 300 for evaporation and heat absorption. In other words, when the temperature control system 10 is in the first working mode, the amount of refrigerant discharged by the compressor 100 and distributed to the hot water heat exchanger 500 and the outdoor heat exchanger 400 by the switching device 200 is not limited, and can be distributed according to needs.

[0047] The temperature control system 10 of the present invention includes a compressor 100, a switching device 200, an indoor heat exchange device 300, an outdoor heat exchange device 400, and a hot water heat exchanger 500. The hot water heat exchanger 500 is installed in a water heater for producing hot water. In the first operating mode, the switching device 200 controls the refrigerant discharged from the compressor 100 to be distributed to the hot water heat exchanger 500 and the outdoor heat exchanger 400 for condensation and heat release. The refrigerant then flows through the indoor heat exchanger 300 for evaporation and heat absorption before returning to the compressor 100. This arrangement ensures that the refrigerant discharged from the compressor 100 can be distributed to the hot water heat exchanger 500 for condensation and heat release to produce hot water, then flows through the indoor heat exchanger 300 for evaporation and heat absorption to cool the room, and finally returns to the compressor. In this way, during the refrigerant circulation process, the temperature control system 10 simultaneously achieves the functions of hot water production and indoor cooling, and the structure of the temperature control system 10 is simple. Alternatively, the switching device 200 can control a portion of the refrigerant to be distributed to the hot water heat exchanger 500 for condensation and heat release to produce hot water, while another portion is distributed to the outdoor heat exchanger 400 for condensation and heat release. Then, the refrigerant flowing out from both the hot water heat exchanger 500 and the outdoor heat exchanger 400 flows into the indoor heat exchanger 300 for evaporation and heat absorption to produce indoor cooling, and finally returns to the compressor 100. Thus, during the refrigerant circulation process, the temperature control system 10 simultaneously achieves the functions of hot water production and indoor cooling, and the indoor environment can be cooled quickly. The structure of the temperature control system 10 is simple. Therefore, the temperature control system 10 of this invention, by setting up a compressor 100, can simultaneously achieve the functions of hot water production and indoor cooling in the first working mode. Furthermore, the temperature control system 10 has a simple structure and the compressor 100 has high energy efficiency. This invention proposes a temperature control system 10 with a simple structure that can simultaneously achieve multiple functions.

[0048] Please see Figure 1 and Figure 2 In one embodiment, the compressor 100 has a first exhaust port 110 and a second exhaust port 120 respectively connected to the switching device 200; the first operating mode includes a first hot water production mode, in which... Figure 2 As shown in the figure, the switching device 200 controls the refrigerant discharged from the first exhaust port 110 of the compressor 100 to flow through the outdoor heat exchange device 400 to condense and release heat, and the refrigerant discharged from the second exhaust port 120 to flow through the hot water heat exchanger 500 to condense and release heat, and then flow through the indoor heat exchange device 300 to evaporate and absorb heat before returning to the compressor 100.

[0049] Understandably, in the first hot water production mode, the refrigerant discharged from the first exhaust port 110 flows through the outdoor heat exchange device 400 to condense and release heat, while the refrigerant discharged from the second exhaust port 120 flows through the hot water heat exchanger 500 to produce hot water, then flows into the indoor heat exchange device 300 to evaporate and absorb heat for indoor cooling, and finally returns to the compressor 100. In this way, during the refrigerant circulation process, the first hot water production mode simultaneously achieves the functions of hot water production and indoor cooling, and the indoor environment can be cooled quickly. The temperature regulation system 10 has a simple structure.

[0050] Furthermore, in the first hot water production mode, the refrigerant flowing from the hot water heat exchanger 500 and the outdoor heat exchange device 400 can converge and flow into the indoor heat exchange device 300 for evaporation and heat absorption, and then return to the compressor 100; or, the refrigerant flowing from the hot water heat exchanger 500 and the outdoor heat exchange device 400 can flow into the indoor heat exchange device 300 for evaporation and heat absorption, and then return to the compressor 100. That is to say, the indoor heat exchange device 300 can have one indoor heat exchange channel, and the refrigerant flowing from the hot water heat exchanger 500 and the outdoor heat exchange device 400 converges and flows into the indoor heat exchange channel for evaporation and heat absorption, and then returns to the compressor 100; or, the indoor heat exchange device 300 can have two indoor heat exchange channels, and the refrigerant flowing from the hot water heat exchanger 500 flows into one of the indoor heat exchange channels for evaporation and heat absorption, and then returns to the compressor 100, while the refrigerant flowing from the outdoor heat exchange device 400 flows into the other indoor heat exchange channel for evaporation and heat absorption, and then returns to the compressor 100. Of course, in other embodiments, the indoor heat exchange device 300 may have multiple indoor heat exchange channels, which will not be described in detail here.

[0051] Therefore, the temperature regulation system 10 of the present invention, by setting a compressor 100, can simultaneously achieve stable hot water production and indoor cooling functions in the first hot water production mode. The temperature regulation system 10 has a simple structure and the compressor 100 has high energy efficiency.

[0052] Please see Figure 1 and Figure 3 In one embodiment, the compressor 100 has a first exhaust port 110 and a second exhaust port 120 respectively connected to the switching device 200; the first operating mode includes a second hot water production mode, in which the second hot water production mode (e.g. Figure 3 As shown in the figure, the switching device 200 controls the refrigerant discharged from the first exhaust port 110 and the second exhaust port 120 of the compressor 100 to flow through the hot water heat exchanger 500 to condense and release heat, and then flow through the indoor heat exchange device 300 to evaporate and absorb heat before returning to the compressor 100.

[0053] Understandably, in the second hot water production mode, the refrigerant discharged from the first exhaust port 110 and the second exhaust port 120 of the compressor 100 flows through the hot water heat exchanger 500 to produce hot water, then flows into the indoor heat exchange device 300 to evaporate and absorb heat for indoor cooling, and finally returns to the compressor 100. In this way, during the refrigerant circulation process, the second hot water production mode simultaneously achieves the functions of rapid hot water production and indoor cooling, and the structure of the temperature regulation system 10 is simple.

[0054] Furthermore, in the second hot water production mode, the refrigerant discharged from the first exhaust port 110 and the second exhaust port 120 of the compressor 100 can converge and flow into the hot water heat exchanger 500 for condensation and heat release; or, the refrigerant discharged from the first exhaust port 110 and the second exhaust port 120 of the compressor 100 can flow into the hot water heat exchanger 500 for condensation and heat release respectively. That is to say, the hot water heat exchanger 500 can have one hot water heat exchange channel, into which the refrigerant discharged from the first exhaust port 110 and the second exhaust port 120 of the compressor 100 converges and flows; or, the hot water heat exchanger 500 can have two hot water heat exchange channels, into which the refrigerant discharged from the first exhaust port 110 of the compressor 100 flows into one of the hot water heat exchange channels for condensation and heat release, and into the other hot water heat exchange channel for condensation and heat release. Similarly, the indoor heat exchange device 300 may have one indoor heat exchange channel; or, the indoor heat exchange device 300 may have two indoor heat exchange channels, with the refrigerant flow method being the same as described above, and will not be repeated here. Of course, in other embodiments, the hot water heat exchanger 500 may have multiple hot water heat exchange channels.

[0055] Therefore, the temperature regulation system 10 of the present invention, by setting a compressor 100, can simultaneously realize the functions of rapid hot water production and indoor cooling in the second hot water production mode. The temperature regulation system 10 has a simple structure and the compressor 100 has high energy efficiency.

[0056] Please see Figure 1 and Figure 4 In one embodiment, the first operating mode further includes a first indoor cooling mode, wherein in the first indoor cooling mode (e.g. Figure 4 As shown in the figure, the switching device 200 controls the refrigerant discharged from the first exhaust port 110 and the second exhaust port 120 of the compressor 100 to flow through the outdoor heat exchange device 400 to condense and release heat, and then flow through the indoor heat exchange device 300 to evaporate and absorb heat before returning to the compressor 100.

[0057] Understandably, in the first indoor cooling mode, the refrigerant discharged from the first exhaust port 110 and the second exhaust port 120 of the compressor 100 flows through the outdoor heat exchange device 400 to condense and release heat, then flows into the indoor heat exchange device 300 to evaporate and absorb heat, thus cooling the room. Finally, it returns to the compressor 100. During this refrigerant flow, the room can cool rapidly. The indoor heat exchange device 300 may have one indoor heat exchange channel; or, it may have two indoor heat exchange channels, in which case the refrigerant is divided into two streams and flows into the two indoor heat exchange channels respectively to evaporate and absorb heat, enabling rapid cooling. Of course, in other embodiments, the indoor heat exchange device 300 may have multiple indoor heat exchange channels. Similarly, the outdoor heat exchange device 400 may have one, two, or multiple outdoor heat exchange channels.

[0058] Therefore, the temperature regulation system 10 of the present invention, by setting a compressor 100, can achieve the function of rapid indoor cooling in the first indoor cooling mode. The temperature regulation system 10 has a simple structure and the compressor 100 has high energy efficiency.

[0059] Please see Figure 1 and Figure 2 In one embodiment, the indoor heat exchange device 300 has a first indoor heat exchange channel 310 and a second indoor heat exchange channel 320. The compressor 100 is connected to the outdoor heat exchange device 400 and the first indoor heat exchange channel 310 in sequence via the switching device 200 to form a first circulation loop. The compressor 100 is connected to the hot water heat exchanger 500 and the second indoor heat exchange channel 320 in sequence via the switching device 200 to form a second circulation loop.

[0060] It is understandable that the first circulation loop can operate as a heating cycle or a cooling cycle. In other words, the first circulation loop can be used for indoor heating or indoor cooling, and the specifics are not limited here.

[0061] Furthermore, the refrigerant flows along the second circulation loop, first flowing through the hot water heat exchanger 500 to condense and release heat for hot water production, then flowing into the second indoor heat exchange channel 320 to evaporate and absorb heat for indoor cooling, and finally returning to the compressor 100. In other words, when the second circulation loop is running, it can simultaneously achieve the functions of hot water production and indoor cooling.

[0062] Furthermore, the first and second circulation loops operate simultaneously. When the first circulation loop is running its refrigeration cycle, the refrigerant discharged from the compressor 100 is divided into two parts. The first part of the refrigerant flows along the first circulation loop, passing through the first indoor heat exchange channel 310 for indoor cooling. The second part of the refrigerant flows along the second circulation loop, passing through the hot water heat exchanger 500 to produce hot water, and then flows into the second indoor heat exchange channel 320 for indoor cooling. Therefore, the temperature control system 10 of this scheme, by setting up a single compressor 100, can simultaneously achieve stable hot water production and indoor cooling functions. The temperature control system 10 has a simple structure, the compressor 100 has high energy efficiency, and the room can be cooled quickly.

[0063] In one embodiment, the switching device 200 is used to control the refrigerant in the first circulation loop to condense and release heat through the outdoor heat exchange device 400 and to control the refrigerant in the second circulation loop to condense and release heat through the hot water heat exchanger 500, so as to form a first hot water production mode. In the first hot water production mode, the pressure of the refrigerant flowing into the hot water heat exchanger 500 is greater than the pressure of the refrigerant flowing into the outdoor heat exchange device 400.

[0064] Understandably, in the first hot water production mode, the refrigerant flows through the hot water heat exchanger 500, condenses and releases heat to produce hot water. The hot water heat exchanger 500, used for hot water production, requires a relatively high temperature, so the refrigerant flowing into the hot water heat exchanger 500 is high-pressure refrigerant. However, the refrigerant flowing through the outdoor heat exchanger 400 does not require a very high temperature to condense and release heat, so the refrigerant flowing into the outdoor heat exchanger 400 is medium-pressure refrigerant. The pressure of the high-pressure refrigerant is greater than that of the medium-pressure refrigerant. There is a pressure difference between the refrigerant in the first circulation loop and the second circulation loop, meaning that the pressure of the refrigerant flowing into the hot water heat exchanger 500 is greater than that of the refrigerant flowing into the outdoor heat exchanger 400.

[0065] Therefore, in the first hot water production mode, by setting up a compressor 100, a pressure difference exists between the refrigerant in the first and second circulation loops of the temperature regulation system 10. This high and low pressure design can reduce the pressure ratio of the compressor 100, making the compressor 100 highly energy efficient, and ensuring that the temperature regulation system 10 can simultaneously achieve stable hot water production and indoor cooling functions.

[0066] In one embodiment, the indoor heat exchange device 300 has a first air duct, and in the first hot water production mode, the second indoor heat exchange channel 320 is located downstream of the first indoor heat exchange channel 310 along the air outlet direction of the first air duct.

[0067] Understandably, in the first hot water production mode, air first flows through the first indoor heat exchange channel 310 in the first air duct, then through the second indoor heat exchange channel 320, and is blown out of the indoor heat exchange device 300. The refrigerant pressure flowing into the hot water heat exchanger 500 is greater than the refrigerant pressure flowing into the outdoor heat exchange device 400, resulting in the refrigerant pressure flowing into the first indoor heat exchange channel 310 being less than the refrigerant pressure flowing into the second indoor heat exchange channel 320. That is, the refrigerant flowing into the first indoor heat exchange channel 310 is a medium-pressure refrigerant, and the refrigerant flowing into the second indoor heat exchange channel 320 is a high-pressure refrigerant. This allows the refrigerant pressure in the indoor heat exchange device 300 to be set in a gradient under the first hot water production mode. The high-pressure refrigerant is more conducive to improving the cooling capacity than the medium-pressure refrigerant. When air flows through the first indoor heat exchange channel 310 and the second indoor heat exchange channel 320, the air first flows through the medium-pressure refrigerant in the indoor heat exchange device 300 and then through the high-pressure refrigerant. This is conducive to improving the indoor cooling capacity. Furthermore, the refrigerant in the two heat exchange channels of the indoor heat exchange device 300 is set with high and low pressure, which is conducive to reducing the pressure ratio of the compressor 100, thereby improving the energy efficiency of the temperature control system 10.

[0068] In one embodiment, the compressor 100 has a first exhaust port 110, a second exhaust port 120, and an intake port 130. The first exhaust port 110 and the intake port 130 are connected to the first circulation loop, and the second exhaust port 120 and the intake port 130 are connected to the second circulation loop. In the first hot water production mode, the exhaust pressure of the second exhaust port 120 is greater than the exhaust pressure of the first exhaust port 110. This configuration means that in the first hot water production mode, the first exhaust port 110 and the second exhaust port 120 of the compressor 100 discharge refrigerant at different pressures. The first exhaust port 110 discharges medium-pressure refrigerant, and the second exhaust port 120 discharges high-pressure refrigerant. This ensures that the refrigerant pressure flowing into the hot water heat exchanger 500 is greater than the refrigerant pressure flowing into the outdoor heat exchanger 400 without the need for an additional pressure regulating device. This simplifies the structure of the temperature control system 10 and ensures that the refrigerant in different circulation return flows of the temperature control system 10 can be designed with high and low pressures in the first hot water production mode, thereby reducing the pressure ratio of the compressor 100 and improving the energy efficiency of the temperature control system 10.

[0069] Please see Figure 1In one embodiment, in the first circulation loop, the outdoor heat exchange device 400 is connected to the first indoor heat exchange channel 310 via a first pipe 201, and in the second circulation loop, the hot water heat exchanger 500 is connected to the second indoor heat exchange channel 320 via a second pipe 202; the switching device 200 includes a first valve body 210 and a first connecting pipe 205, one end of the first connecting pipe 205 is connected to the first pipe 201, and the other end of the first connecting pipe 205 is connected to the second pipe 202, and the first valve body 210 is disposed on the first connecting pipe 205.

[0070] Understandably, when the first circulation loop operates in the refrigeration cycle, if the first valve body 210 is open, the refrigerant flowing into the first indoor heat exchange channel 310 along the first pipe 201 can flow sequentially through the first connecting pipe 205 and part of the second pipe 202 before flowing into the second indoor heat exchange channel 320. That is, the opening of the first valve body 210 allows the refrigerant flowing into the first indoor heat exchange channel 310 to be diverted to the second indoor heat exchange channel 320, thereby adjusting the ratio of refrigerant flowing into the first indoor heat exchange channel 310 and the second indoor heat exchange channel 320. Similarly, when the second circulation loop operates, if the first valve body 210 is open, the refrigerant flowing into the second indoor heat exchange channel 320 can be diverted to the first indoor heat exchange channel 310, thereby adjusting the ratio of refrigerant flowing into the first indoor heat exchange channel 310 and the second indoor heat exchange channel 320. If the first valve body 210 is closed, the refrigerant on the first pipe 201 and the second pipe 202 will not be diverted to each other, and the refrigerant flowing into the first indoor heat exchange channel 310 and the second indoor heat exchange channel 320 will not affect each other.

[0071] Therefore, by setting the first valve body 210 and the first connecting pipe 205, the proportion of refrigerant flowing into the first indoor heat exchange channel 310 and the second indoor heat exchange channel 320 can be adjusted, and the temperature control system 10 can have multiple working modes, thus improving the applicability of the temperature control system 10.

[0072] Please see Figure 2In one embodiment, the switching device 200 further includes a second connecting pipe 206, a second valve body 220, and a third valve body 230. The switching device 200 is connected to the outdoor heat exchange device 400 via a third pipe 203, and to the hot water heat exchanger 500 via a fourth pipe 204. One end of the second connecting pipe 206 is connected to the third pipe 203, and the other end of the second connecting pipe 206 is connected to the fourth pipe 204 or the hot water heat exchanger 500. The second valve body 220 is disposed on the second connecting pipe 206, and the third valve body 230 is disposed on the third pipe 203 connecting one end of the second connecting pipe 206 to the outdoor heat exchange device 400. Thus, by providing the second connecting pipe 206, the first circulation loop and the second circulation loop can be connected, and by providing the second valve body 220 and the third valve body 230, the flow direction of the refrigerant can be controlled, enabling the temperature control system 10 to have multiple modes.

[0073] Please see Figure 2 In one embodiment, the compressor 100 has a first exhaust port 110 and a second exhaust port 120 respectively connected to the switching device 200; the first operating mode includes a first hot water production mode, in which the first valve body 210 is closed, the second valve body 220 is closed, and the third valve body 230 is open. The switching device 200 controls the refrigerant discharged from the first exhaust port 110 of the compressor 100 to flow along the first circulation loop, and the refrigerant discharged from the second exhaust port 120 to flow along the second circulation loop. Thus, the refrigerant discharged from the first exhaust port 110 of the compressor 100 flows through the outdoor heat exchanger 400 to condense and release heat, then flows into the first indoor heat exchange channel 310 to evaporate and absorb heat for indoor cooling; the refrigerant discharged from the second exhaust port 120 of the compressor 100 flows through the hot water heat exchanger 500 to condense and release heat for hot water production, then flows into the second indoor heat exchange channel 320 to evaporate and absorb heat for indoor cooling, and finally returns to the compressor 100. Therefore, in the first hot water production mode, by opening or closing multiple valves, the temperature regulation system 10 uses a single compressor 100 to achieve the functions of simultaneously and stably producing hot water and cooling the room. The temperature regulation system 10 has a simple structure and the compressor 100 has high energy efficiency.

[0074] Please see Figure 3In one embodiment, the compressor 100 has a first exhaust port 110 and a second exhaust port 120 respectively connected to the switching device 200; the first working mode includes a second hot water production mode, in which the first valve body 210 is open, the second valve body 220 is open, and the third valve body 230 is closed. The switching device 200 controls the refrigerant discharged from the first exhaust port 110 and the second exhaust port 120 of the compressor 100 to flow through the hot water heat exchanger 500 to condense and release heat, and then to be diverted to the first indoor heat exchange channel 310 and the second indoor heat exchange channel 320 for evaporation and heat absorption. In this configuration, the first and second circulation loops are connected via the second connecting pipe 206. The refrigerant discharged from the first exhaust port 110 and the second exhaust port 120 of the compressor 100 flows into the hot water heat exchanger 500 for condensation and heat release, thus producing hot water quickly. The refrigerant flowing out of the hot water heat exchanger 500 flows along the second pipe 202. A portion of the refrigerant in the second pipe 202 flows into the second indoor heat exchange channel 320 for evaporation and heat absorption, thus providing indoor cooling. The other portion of the refrigerant in the second pipe 202 is diverted by the first valve body 210 and flows into the first indoor heat exchange channel 310 for evaporation and heat absorption, again providing indoor cooling, before finally returning to the compressor 100. Therefore, in the second hot water production mode, by opening or closing multiple valves, the temperature control system 10 uses a single compressor 100 to simultaneously and rapidly produce hot water and provide indoor cooling. The temperature control system 10 has a simple structure, and the compressor 100 has high energy efficiency.

[0075] In one embodiment, the hot water heat exchanger 500 has a first hot water heat exchange channel, and the other end of the second connecting pipe 206 is connected to the fourth pipe 204. The first operating mode includes a second hot water production mode. In the second hot water production mode, the switching device 200 controls the refrigerant discharged from the compressor 100 to converge in the fourth pipe 204 and then flow into the first hot water heat exchange channel for condensation and heat release. It can be understood that there can be only one first hot water heat exchange channel. The refrigerant discharged from the first exhaust port 110 and the second exhaust port 120 of the compressor 100 first converges in the fourth pipe 204 and then flows into the first hot water heat exchange channel for condensation and heat release. This simplifies the structure of the hot water heat exchanger 500.

[0076] In another embodiment, the hot water heat exchanger 500 has a first hot water heat exchange channel and a second hot water heat exchange channel that are independent of each other and spaced apart. One of the first hot water heat exchange channel and the second hot water heat exchange channel is connected to the other end of the second connecting pipe 206, and the other is connected to the fourth pipe 204. This arrangement allows the refrigerant discharged from the first exhaust port 110 of the compressor 100 to flow into the first hot water heat exchange channel for condensation and heat release, thus producing hot water. Similarly, the refrigerant discharged from the second exhaust port 120 of the compressor 100 can flow into the second hot water heat exchange channel for condensation and heat release, also producing hot water. The independent arrangement of the first and second hot water heat exchange channels ensures full utilization of the refrigerant flowing through the hot water heat exchanger 500, facilitating rapid hot water production and improving the efficiency of hot water production.

[0077] Please see Figure 2 and Figure 3 In one embodiment, the switching device 200 further includes a fourth valve body 240, the other end of the second connecting pipe 206 is connected to the fourth pipeline 204, and the fourth valve body 240 is disposed on the fourth pipeline 204 connecting the other end of the second connecting pipe 206 to the hot water heat exchanger 500; in the first hot water production mode or the second hot water production mode, the fourth valve body 240 is opened.

[0078] Understandably, in the first operating mode, by setting the fourth valve body 240, the refrigerant flowing into the hot water heat exchanger 500 along the fourth pipe 204 can be controlled. If the fourth valve body 240 is open, the high-temperature refrigerant discharged from the compressor 100 can flow into the hot water heat exchanger 500 through the fourth valve body 240 to release heat and produce hot water. If the fourth valve body 240 is closed, the high-temperature refrigerant discharged from the compressor 100 cannot flow into the hot water heat exchanger 500 through the fourth pipe 204. That is, by controlling the opening or closing of the fourth valve body 240, the operating mode of the temperature regulation system 10 can be adjusted, which facilitates the control of the temperature regulation system 10.

[0079] Please see Figure 4In one embodiment, the first operating mode includes a first indoor cooling mode. In the first indoor cooling mode, the first valve body 210 is open, the second valve body 220 is open, the third valve body 230 is open, and the fourth valve body 240 is closed. The switching device 200 controls the refrigerant discharged from the first exhaust port 110 and the second exhaust port 120 of the compressor 100 to flow through the outdoor heat exchange device 400 to condense and release heat, and then divert it to the first indoor heat exchange channel 310 and the second indoor heat exchange channel 320 to evaporate and absorb heat. In this configuration, the first circulation loop and the second circulation loop are connected through the second connecting pipe 206. The refrigerant discharged from the first exhaust port 110 of the compressor 100 flows along the third pipe 203, and the refrigerant discharged from the second exhaust port 120 of the compressor 100 flows along the fourth pipe 204 and the second connecting pipe 206 in sequence. Then, it converges with the refrigerant discharged from the first exhaust port 110 into the third pipe 203, and then flows into the outdoor heat exchange device 400 to condense and release heat. The refrigerant flowing out of the outdoor heat exchange device 400 flows along the first pipe 201. A portion of the refrigerant in the first pipe 201 flows into the first indoor heat exchange channel 310 to evaporate and absorb heat for indoor cooling. Another portion of the refrigerant in the first pipe 201 is diverted by the first valve body 210 and flows into the second indoor heat exchange channel 320 to evaporate and absorb heat for indoor cooling. Finally, it returns to the compressor 100. Therefore, in the first indoor cooling mode, by opening or closing multiple valves, the temperature control system 10 uses a compressor 100 to achieve the function of rapid indoor cooling. The temperature control system 10 has a simple structure and the compressor 100 has high energy efficiency.

[0080] In one embodiment, the indoor heat exchange device 300 includes a first heat exchange tube and a second heat exchange tube. The first heat exchange tube has a first indoor heat exchange channel 310, and the second heat exchange tube has a second indoor heat exchange channel 320. The first heat exchange tube and the second heat exchange tube are independent of each other and are spaced apart.

[0081] It is understood that the indoor heat exchange device 300 also includes first heat exchange plates. When the first heat exchange tube and the second heat exchange tube are independently and spaced apart, both the first heat exchange tube and the second heat exchange tube are provided with first heat exchange plates to form a first heat exchanger and a second heat exchanger. The first heat exchanger and the second heat exchanger can be housed in the same housing, or they can be housed in different housings. In this embodiment, the first heat exchanger and the second heat exchanger are housed in the same housing, and they can exchange heat with each other, which is beneficial to improving the heat exchange efficiency of the indoor heat exchange device 300.

[0082] In another embodiment, the indoor heat exchange device 300 includes a first heat exchange tube and a second heat exchange tube. The first heat exchange tube has a first indoor heat exchange channel 310, and the second heat exchange tube has a second indoor heat exchange channel 320. At least one of the first heat exchange tube and the second heat exchange tube is located within the other, and a flow gap for refrigerant to pass through is provided between the first heat exchange tube and the second heat exchange tube. With this arrangement, taking the first heat exchange tube being at least partially located within the second heat exchange tube as an example, the refrigerant in the second heat exchange tube can better exchange heat with the refrigerant in the first heat exchange tube, thereby improving the heat exchange efficiency of the refrigerant flowing through the indoor heat exchange device 300.

[0083] In one embodiment, the flow gap is an annular structure. This arrangement helps to increase the heat exchange area of ​​the refrigerant flowing through the first and second heat exchange tubes, thereby further improving the heat exchange efficiency of the refrigerant.

[0084] In one embodiment, both the first heat exchange tube and the second heat exchange tube are coil structures. This arrangement helps to increase the heat exchange area of ​​the first indoor heat exchange channel 310 and the second indoor heat exchange channel 320, prolong the heat exchange time of the refrigerant, and thus improve the heat exchange effect.

[0085] In one embodiment, the first indoor heat exchange channel 310 and the second indoor heat exchange channel 320 are disposed in the same housing. It is understood that the indoor heat exchange device 300 has a first housing, and both the first indoor heat exchange channel 310 and the second indoor heat exchange channel 320 are disposed within the first housing. When a portion of the refrigerant flows through the first indoor heat exchange channel 310 for heat exchange, and another portion flows through the second indoor heat exchange channel 320 for heat exchange, if the temperatures of the first indoor heat exchange channel 310 and the second indoor heat exchange channel 320 after heat exchange are different and a temperature difference exists, then the first indoor heat exchange channel 310 and the second indoor heat exchange channel 320 within the first housing can exchange heat. The lower-temperature channel absorbs the heat from the higher-temperature channel, thus improving heat exchange efficiency and enhancing the energy efficiency of the temperature control system 10.

[0086] Please see Figure 1 In one embodiment, the compressor 100 has a first exhaust port 110, a second exhaust port 120 and an intake port 130, wherein the first exhaust port 110 and the intake port 130 are connected to the first circulation loop, and the second exhaust port 120 and the intake port 130 are connected to the second circulation loop.

[0087] It is understood that there is only one compressor 100. The first exhaust port 110 is independently connected to the first circulation loop, and the second exhaust port 120 is independently connected to the second circulation loop. The exhaust pressures of the first exhaust port 110 and the second exhaust port 120 of the compressor 100 can be the same or different, so that the refrigerant pressure flowing into the first circulation loop and the second circulation loop can be the same or different, thereby meeting the needs of different operating modes. This solution can have multiple modes through one compressor 100, such as: first hot water mode, second hot water mode, and first indoor cooling mode, etc. The temperature control system 10 of this solution has high energy efficiency.

[0088] Please see Figure 1 In one embodiment, the compressor 100 is a dual-cylinder dual-suction dual-exhaust compressor, and the intake port 130 includes a first sub-intake port 131 and a second sub-intake port 132. The first sub-intake port 131 is connected to the first circulation loop, and the second sub-intake port 132 is connected to the second circulation loop.

[0089] Understandably, in a dual-cylinder, dual-suction, dual-exhaust compressor, the first sub-intake port 131 and the second sub-intake port 132 independently return air, and their intake pressures can be the same or different. Similarly, the first exhaust port 110 and the second exhaust port 120 independently exhaust air, and their exhaust pressures can be the same or different, ensuring that the return air of the first and second circulation loops and the intake air do not affect each other. This design utilizes the simultaneous operation of two compression cylinders, increasing the intake and exhaust volume of the compressor 100, thereby improving the compression capacity of the compressor 100 and consequently enhancing the energy efficiency of the temperature control system 10.

[0090] Please see Figure 1 In one embodiment, the switching device 200 includes a first reversing valve 250 and a second reversing valve 260. The first reversing valve 250 is connected to the first circulation loop to change the refrigerant flow direction in the first circulation loop; the second reversing valve 260 is connected to the second circulation loop to change the refrigerant flow direction in the second circulation loop.

[0091] It is understood that the first reversing valve 250 and the second reversing valve 260 can be composed of multiple valve bodies or a four-way reversing valve; the specific configuration is not limited here. In this solution, the first reversing valve 250 includes a four-way reversing valve; and / or, the second reversing valve 260 includes a four-way reversing valve. The use of four-way reversing valves allows for simple and effective switching of the refrigerant flow direction, simplifying the structure of the temperature control system 10 and making it easy to assemble. This solution uses the first reversing valve 250 to change the refrigerant flow direction in the first circulation loop and the second reversing valve 260 to change the refrigerant flow direction in the second circulation loop, enabling the heat exchange system to have multiple modes and increasing the applicability of the temperature control system 10.

[0092] Please see Figures 1 to 4 In one embodiment, the switching device 200 includes a first throttling element 270 and a second throttling element 280. The first throttling element 270 is disposed in the first circulation loop and located between the outdoor heat exchange device 400 and the first indoor heat exchange channel 310. The second throttling element 280 is disposed in the second circulation loop and located between the hot water heat exchanger 500 and the second indoor heat exchange channel 320.

[0093] It is understood that the refrigerant in the first circulation loop is throttled by setting the first throttling device 270, and the refrigerant in the second circulation loop is throttled by setting the second throttling device 280. The first throttling device 270 and / or the second throttling device 280 are electronic expansion valves.

[0094] The temperature control system 10 has multiple operating modes. Figures 2 to 4 The arrows in the diagram indicate the direction of refrigerant flow, as shown below:

[0095] Please see Figure 2 In the first hot water production mode, the first valve body 210 is closed, the second valve body 220 is closed, the third valve body 230 is open, and the fourth valve body 240 is open. The refrigerant discharged from the first exhaust port 110 of the compressor 100 flows through the outdoor heat exchange device 400 to condense and release heat under the switching of the first reversing valve 250, and then flows through the first indoor heat exchange channel 310 to evaporate and absorb heat for indoor cooling after being throttled by the first throttling element 270. Finally, it flows back to the first sub-suction port 131 of the compressor 100 after passing through the first reversing valve 250. The refrigerant discharged from the second exhaust port 120 of the compressor 100 flows through the hot water heat exchanger 500 to condense and release heat for hot water production under the switching of the second reversing valve 260, and then flows through the second indoor heat exchange channel 320 to evaporate and absorb heat for indoor cooling after being throttled by the second throttling element 280. Finally, it flows back to the second sub-suction port 132 of the compressor 100 after passing through the second reversing valve 260.

[0096] Therefore, the temperature regulation system 10 of the present invention, by setting a compressor 100, can simultaneously achieve stable hot water production and indoor cooling functions in the first hot water production mode. The temperature regulation system 10 has a simple structure and the compressor 100 has high energy efficiency.

[0097] Please see Figure 3 In the second hot water production mode, the first valve body 210 is open, the second valve body 220 is open, the third valve body 230 is closed, and the fourth valve body 240 is open. The refrigerant discharged from the first exhaust port 110 of the compressor 100, under the switching of the first reversing valve 250, flows along the second connecting pipe 206 and the fourth pipe 204 into the hot water heat exchanger 500 for condensation and heat release. The refrigerant discharged from the second exhaust port 120 of the compressor 100, under the switching of the second reversing valve 260, flows along the fourth pipe 204 into the hot water heat exchanger 500 for condensation and heat release, thus producing hot water. Both the refrigerant discharged from the first exhaust port 110 and the second exhaust port 120 of the compressor 100 flow into the hot water system. The heat exchanger 500 produces hot water quickly. The refrigerant flowing out of the hot water heat exchanger 500 flows along the second pipe 202. After being throttled by the second throttling device 280, a portion of the refrigerant in the second pipe 202 flows into the second indoor heat exchange channel 320 to evaporate and absorb heat for indoor cooling. Finally, it flows through the second reversing valve 260 and returns to the second sub-suction port 132 of the compressor 100. The other portion of the refrigerant in the second pipe 202 is diverted by the first valve body 210 and flows into the first indoor heat exchange channel 310 to evaporate and absorb heat for indoor cooling. Finally, it flows through the first reversing valve 250 and returns to the first sub-suction port 131 of the compressor 100.

[0098] Therefore, the temperature regulation system 10 of the present invention, by setting a compressor 100, can simultaneously realize the functions of rapid hot water production and indoor cooling in the second hot water production mode. The temperature regulation system 10 has a simple structure and the compressor 100 has high energy efficiency.

[0099] Please see Figure 4In the first indoor cooling mode, the first valve body 210 is open, the second valve body 220 is open, the third valve body 230 is open, and the fourth valve body 240 is closed. The refrigerant discharged from the first discharge port 110 of the compressor 100 flows along the third pipe 203 under the switching of the first reversing valve 250. The refrigerant discharged from the second discharge port 120 of the compressor 100 flows sequentially along the fourth pipe 204 and the second connecting pipe 206 under the switching of the second reversing valve 260. Then, it converges with the refrigerant discharged from the first discharge port 110 into the third pipe 203, and flows into the outdoor heat exchanger 400 for condensation and heat release. Finally, it flows along the first pipe 201 towards... The refrigerant flowing from the outdoor heat exchanger 400 flows along the first pipe 201. After being throttled by the first throttling device 270, a portion of the refrigerant in the first pipe 201 flows into the first indoor heat exchange channel 310 to evaporate and absorb heat for indoor cooling. Finally, it flows through the first reversing valve 250 and returns to the first sub-suction port 131 of the compressor 100. The other portion of the refrigerant in the first pipe 201 flows into the second indoor heat exchange channel 320 to evaporate and absorb heat for indoor cooling after being diverted by the first valve body 210. Finally, it flows through the second reversing valve 260 and returns to the second sub-suction port 132 of the compressor 100.

[0100] Therefore, the temperature regulation system 10 of the present invention, by setting a compressor 100, can achieve the function of rapid indoor cooling in the first indoor cooling mode. The temperature regulation system 10 has a simple structure and the compressor 100 has high energy efficiency.

[0101] Furthermore, the temperature control system 10 can also have a second indoor cooling mode. In this mode, the first circulation loop operates in a cooling cycle, while the second circulation loop does not operate. Similarly, the temperature control system 10 can also have a heating mode. In this mode, the first circulation loop operates in a heating cycle, while the second circulation loop does not operate. Therefore, the temperature control system 10 in this solution can have multiple operating modes, has a simple structure, and the compressor 100 has high energy efficiency.

[0102] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
