The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

Fig. 1 is a schematic structural diagram of a hydro module of an air conditioning system according to an embodiment of the present invention. As shown in fig. 1, a hydro module 10 of an air conditioning system according to an embodiment of the present invention may include a first heat exchanger 100, a second heat exchanger 200, a first compressor 300, a first throttling device 400, and a radiator 500.
The outdoor unit side of the first heat exchanger 100 is connected to an outdoor unit of the air conditioning system through a liquid pipe and a high-pressure gas pipe of the air conditioning system, and forms a first refrigerant loop (where "→" represents a flowing direction of a refrigerant in the first refrigerant loop); the waterway side of the second heat exchanger 200 is connected to the waterway module and forms a waterway circuit (wherein "→" represents a flow direction of water in the waterway circuit); the first compressor 300 is arranged between the hydraulic side of the first heat exchanger 100 and the hydraulic side of the second heat exchanger 200, and the first compressor 300 forms a second refrigerant circuit through the hydraulic side of the second heat exchanger 200 and the hydraulic side of the first heat exchanger 100 (wherein "→" represents a flow direction of a refrigerant in the second refrigerant circuit); a first throttling device 400 (for example, a first electromagnetic expansion valve) is connected in series in the first refrigerant circuit; the heat sink 500 is connected in series in the first refrigerant circuit, and the heat sink 500 is disposed opposite to the electric control unit of the hydraulic module 100 to dissipate heat from the electric control unit by using the first refrigerant circuit.
According to an embodiment of the present invention, as shown in fig. 1, a first end a of the first heat exchanger 100 on the outdoor side is connected to a liquid pipe of the air conditioning system through a first throttling means 400, and a second end b of the first heat exchanger 100 on the outdoor side is connected to a high pressure gas pipe of the air conditioning system, wherein a radiator 500 is connected between the first throttling means 400 and the liquid pipe of the air conditioning system.
According to an embodiment of the present invention, the first refrigerant circuit may use the R410a refrigerant, and the second refrigerant circuit may use the R134a refrigerant.
Specifically, as shown in fig. 2, a second throttling device (for example, a second electromagnetic expansion valve) is further connected in series in the second refrigerant circuit, wherein a first end c on the hydraulic side of the first heat exchanger 100 is connected to a first end e on the hydraulic side of the second heat exchanger 200 through the second throttling device, a second end d on the hydraulic side of the first heat exchanger 100 is connected to the return air port of the first compressor 300, a second end f on the hydraulic side of the second heat exchanger 200 is connected to the exhaust port of the first compressor 300, and in addition, the outdoor unit side of the first heat exchanger 100 may be further connected to a refrigerant switching device, wherein the refrigerant switching device is connected to the ordinary air-cooled indoor unit. When the hydraulic module starts to work, the R410a refrigerant and the R134a refrigerant circulate in the corresponding refrigerant circuits, wherein the pressure-enthalpy diagrams corresponding to the R410a refrigerant and the R134a refrigerant are shown in fig. 3.
In the second refrigerant circuit, the first compressor 300 compresses the R134a refrigerant into high-temperature and high-pressure gas, and the gas is discharged from the discharge port of the first compressor 300 and is delivered to the second end f on the hydraulic side of the second heat exchanger 200 (which may be a condenser plate exchanger). The high-temperature and high-pressure gas releases heat in the second heat exchanger 200, is converted into a high-temperature and high-pressure liquid, and is delivered to the second throttling device through the first end e of the hydraulic side of the second heat exchanger 200. The high-temperature and high-pressure liquid is throttled by the second throttling device and then converted into a low-temperature and low-pressure two-phase refrigerant, and the low-temperature and low-pressure two-phase refrigerant is delivered to the first end c of the hydraulic side of the first heat exchanger 100. The low-temperature low-pressure two-phase refrigerant absorbs heat of the outdoor unit in the first heat exchanger 100, is converted into low-temperature low-pressure gas, and is delivered to the return port of the first compressor 300 through the second end d on the hydraulic side of the first heat exchanger 200, thereby completing the circulation flow of the R134a refrigerant in the second refrigerant circuit.
In the first refrigerant circuit, the outer compressor compresses the R410a refrigerant into a high-temperature and high-pressure gas, and transmits the gas to the second end b of the first heat exchanger 100 on the outdoor side through the high-pressure gas pipe, and the high-temperature and high-pressure gas releases heat in the first heat exchanger 100 and is converted into a high-temperature and high-pressure liquid, and is transmitted to the first throttling device 400 through the first end a of the first heat exchanger 100 on the outdoor side. The high-temperature and high-pressure liquid is throttled by the first throttling device 400, converted into an intermediate-pressure liquid (intermediate-pressure liquid refrigerant), and sent to the radiator 500. When the medium-pressure liquid passes through the radiator 500, the medium-pressure liquid can exchange heat with the electric control component to dissipate heat of the electric control component, so that the purpose of dissipating heat of the electric control component through the first refrigerant loop is achieved.
It should be noted that after passing through the heat sink 500, the medium-pressure liquid may selectively flow into the outdoor unit for throttling and then evaporating or selectively flow into the refrigerant switching device, and then flow into the ordinary air-cooled indoor unit for throttling and then evaporating after being distributed by the refrigerant switching device, according to the states of the ordinary air-cooled indoor unit and the ordinary air-cooled outdoor unit. The medium-pressure liquid refrigerant is converted into low-temperature and low-pressure gas after being evaporated, and the low-temperature and low-pressure gas is conveyed to the outer compressor, so that the circulating flow of the R410a refrigerant in the first refrigerant loop is completed.
Further, when the electronic control component is cooled in the above manner, the electronic control component may have a risk of condensation, and how to effectively avoid the condensation of the electronic control component is described in detail below with reference to the specific embodiment of the present invention.
According to an embodiment of the present invention, as shown in fig. 4, the hydro module 10 of the air conditioning system further includes a first temperature detector 600, a second temperature detector 700, and a controller 800.
The first temperature detection device 600 is configured to generate a first temperature detection signal, where the first temperature detection signal is used to indicate a temperature of a refrigerant of the heat sink 500; the second temperature detector 700 is configured to generate a second temperature detection signal, wherein the second temperature detection signal is indicative of a temperature of the electronic control component; the controller 800 is connected to the first temperature detector 600, the second temperature detector 700, and the first throttling device 400, and the controller 800 is configured to adjust the opening degree of the first throttling device 400 according to the first temperature detection signal and the second temperature detection signal.
It should be noted that the first temperature detector 600 may be disposed between the first throttling device 400 and the first heat exchanger 100 to determine the temperature of the refrigerant of the heat sink 500 according to the temperature of the refrigerant before being throttled by the first throttling device 400; alternatively, the first temperature detector 600 may be disposed between the first throttling device 400 and the inlet of the heat sink 500, so as to determine the temperature of the refrigerant of the heat sink 500 according to the temperature of the refrigerant throttled by the first throttling device 400; alternatively, the first temperature detector 600 may be disposed at an outlet of the heat sink 500 to determine the temperature of the refrigerant flowing out of the heat sink 500.
According to an embodiment of the present invention, the controller 800 is configured to increase the opening degree of the first throttling device 400 if it is determined that the temperature of the refrigerant of the radiator 500 is lower than the temperature of the electric control component according to the first temperature detection signal and the second temperature detection signal.
According to an embodiment of the present invention, the controller 800 is configured to send a heat radiation protection signal to an outdoor unit of the air conditioning system when it is determined that the opening degree of the first throttling device 400 reaches the maximum opening degree, so that the outdoor unit increases a discharge pressure of a second compressor in the outdoor unit according to the heat radiation protection signal.
Specifically, when the electronic control component is cooled in the above manner, the controller 800 may obtain a first temperature detection signal generated by the first temperature detector 600 in real time, obtain a second temperature detection signal generated by the second temperature detector 700 in real time, obtain the corresponding refrigerant temperature T1 of the heat sink 500 and the temperature Ta of the electronic control component according to the first temperature detection signal and the second temperature detection signal, and compare the magnitude relationship between the two. If the refrigerant temperature T1 of the heat sink 500 is greater than or equal to the temperature Ta of the electronic control component, it indicates that there is no condensation risk in the heat sink 500, and therefore, there is no need to perform condensation prevention protection on the heat sink 500; if the refrigerant temperature T1 of the radiator 500 is less than the temperature Ta of the electronic control component, it indicates that there is a risk of condensation in the radiator 500, and at this time, the controller 800 may increase the opening degree of the first throttle device 400 to reduce the throttling effect of the first throttle device 400, so as to increase the refrigerant temperature T1 of the radiator 500.
Further, after the opening degree of the first throttle device 400 is increased by the controller 800, the first temperature detection signal is still acquired by the first temperature detection device 600, and the second temperature detection signal is acquired by the second temperature detector 700. If the controller 800 determines that the temperature of the refrigerant of the radiator 500 is greater than or equal to the temperature of the electric control component according to the first temperature detection signal and the second temperature detection signal, it indicates that the radiator 500 does not have a condensation risk at the moment, and the hydraulic module can be normally controlled; if the controller 800 determines that the temperature of the refrigerant of the radiator 500 is still less than the temperature of the electric control part according to the first temperature detection signal and the second temperature detection signal, the opening degree of the first throttle device 400 is continuously increased. When the opening degree of the first throttling device 400 reaches the maximum opening degree and the temperature of the refrigerant of the radiator 500 is still lower than the temperature of the electric control component, a heat radiation protection signal is sent to the outdoor unit of the air conditioning system. After receiving the heat dissipation protection signal, the outdoor unit may increase a discharge pressure of the second compressor (an outdoor unit compressor) in the outdoor unit, for example, by increasing an operating frequency of the second compressor or increasing a damper of the outdoor fan, so as to increase the discharge pressure of the second compressor in the outdoor unit, thereby continuously increasing the refrigerant temperature T1 of the heat sink 500, and further effectively preventing the heat sink from generating condensation.
Therefore, in the process of radiating the electric control component by using the refrigerant loop, the refrigerant temperature of the radiator and the temperature of the electric control component are detected in real time, and the radiator is protected from condensation according to the size relation, so that the radiator can be effectively prevented from condensation.
In summary, according to the hydraulic module of the air conditioning system in the embodiment of the present invention, the outdoor unit side of the first heat exchanger is connected to the outdoor unit of the air conditioning system through the liquid pipe and the high pressure gas pipe of the air conditioning system to form a first refrigerant circuit, the water path side of the second heat exchanger is connected to the water path module to form a water path circuit, the first compressor is disposed between the water path side of the first heat exchanger and the water path side of the second heat exchanger, the first compressor forms a second refrigerant circuit through the water path side of the second heat exchanger and the water path side of the first heat exchanger, the first throttling device is connected in series to the first refrigerant circuit, the radiator is connected in series to the first refrigerant circuit, and the radiator is disposed opposite to the electric control unit of the hydraulic module to radiate heat from the electric control unit by using the first refrigerant circuit. Therefore, the electric control component is cooled by the refrigerant loop without additionally increasing a cooling fan and an air channel, so that the occupation of space is reduced, and the production cost is greatly reduced.
In addition, the embodiment of the invention also provides an air conditioning system which comprises an outdoor unit, at least one indoor unit and the hydraulic module, wherein the at least one indoor unit and the hydraulic module are respectively connected with the outdoor unit.
