[0024] Please refer to Figures 1-3 This application provides a wall-mounted water chiller, comprising:

[0025] The water chiller body 100 is provided with a fan 110, a refrigerant passage 200, a first circulating water passage 300, a second circulating water passage 400, a compressor 120, a condenser 130, a heat exchanger 140, and a heat exchange evaporator 150.

[0026] The compressor 120 and the condenser 130 are disposed on the refrigerant passage 200;

[0027] The refrigerant inlet 151 and refrigerant outlet 152 of the heat exchange evaporator 150 are both connected to the refrigerant passage 200, and the circulating water inlet 153 and circulating water outlet 154 of the heat exchange evaporator 150 are both connected to the first circulating water passage 300.

[0028] The air radiator heat exchanger 140 is installed on the second circulating water passage 400. The air radiator heat exchanger 140 is stacked with the condenser 130, and the air radiator heat exchanger 140 and the condenser 130 share the fan 110.

[0029] Specifically, the main body 100 of the water chiller is a wall-mounted structure. The refrigerant passage 200, the first circulating water passage 300, and the second circulating water passage 400 are all located on the main body 100. The refrigerant passage 200 has a refrigerant inlet 201 and a refrigerant outlet 202. The refrigerant enters the refrigerant passage 200 through the refrigerant inlet 201 and exits through the refrigerant outlet 202, circulating within the refrigerant passage 200. The first circulating water passage 300 includes a first inlet 301 and a first outlet 302. 02, the circulating water in the first circulating water passage 300 enters the first circulating water passage 300 through the first inlet 301 and exits the second circulating water passage 400 through the first outlet 302; the second circulating water passage 400 includes a second inlet 401 and a second outlet 402, the circulating water in the second circulating water passage 400 enters the second circulating water passage 400 through the second inlet 401 and exits the second circulating water passage 402; the water chiller exchanges heat through the first circulating water passage 300 and the second circulating water passage 400.

[0030] A compressor 120 and a condenser 130 are installed on the refrigerant passage 200, such as Figure 3 As shown, the input and output ends of compressor 120 are connected to refrigerant passage 200, and the input and output ends of condenser 130 are also connected to refrigerant passage 200. Condenser 130 is located at the rear end of compressor 120. Refrigerant is pressurized by compressor 120 and enters condenser 130. As refrigerant passes through condenser 130, heat exchange occurs between the fan 110 and condenser 130, transforming the high-temperature gaseous refrigerant into a low-temperature liquid refrigerant. Compressor 120 is installed at one end of water chiller body 100, and condenser 130 is installed in the middle of water chiller body 100. Figure 1 and Figure 2 As shown.

[0031] A heat exchange evaporator 150 is also provided on the refrigerant passage 200. The heat exchange evaporator 150 includes a refrigerant side and a circulating water side. The refrigerant side includes a refrigerant inlet 151 and a refrigerant outlet 152. The refrigerant inlet 151 is connected to the refrigerant discharge section of the refrigerant passage 200, and the refrigerant outlet 152 is connected to the refrigerant inlet 201 of the refrigerant passage 200. The circulating water side includes a circulating water inlet 153 and a circulating water outlet 154. Both the circulating water inlet 153 and the circulating water outlet 154 are connected to the first circulating water passage 300. The circulating water in the first circulating water passage 300 and the refrigerant in the refrigerant passage 200 exchange heat in the heat exchange evaporator 150.

[0032] A heat exchanger 140 is installed on the second circulating water passage 400, and the heat exchanger 140 exchanges heat with the second circulating water passage 400 with the assistance of a fan 110. Figure 3 As shown, the air-dissipation heat exchanger 140 is located on the second circulating water passage 400 and corresponds to the position of the condenser 130. That is, the air-dissipation heat exchanger 140 and the condenser 130 are stacked on top of each other and both are assisted by the fan 110 for heat dissipation. The water chiller can choose to exchange heat through the condenser 130 alone, or through the air radiator heat exchanger 140 alone, or through both the condenser 130 and the air radiator heat exchanger 140. When heat exchange is selected through the condenser 130 alone, the fan 110 and compressor 120 are started, and only the circulating water in the first circulating water passage 300 is kept flowing, thereby exchanging heat with the circulating water in the first circulating water passage 300. When heat exchange is selected through the air radiator heat exchanger 140, the fan 110 is started, and only the circulating water in the second circulating water passage 400 is kept flowing, thereby exchanging heat with the circulating water in the second circulating water passage 400. When heat exchange is selected through both the condenser 130 and the air radiator heat exchanger 140, the fan 110 and compressor 120 are started, and both the first circulating water passage 300 and the second circulating water passage 400 are kept flowing, thereby exchanging heat with the circulating water in both the first circulating water passage 300 and the second circulating water passage 400 simultaneously.

[0033] By integrating the air-dissipative heat exchanger 140 onto the main body 100 of the water chiller, heat exchange can be achieved under low-temperature conditions simply by turning on the fan 110 and allowing heat to be exchanged through the air-dissipative heat exchanger 140, without needing to turn on the compressor 120 and start the refrigerant cycle. This achieves energy saving and efficiency improvement. The air-dissipative heat exchanger 140 is installed in the middle of the main body 100 of the water chiller, and the fan 110 is installed on the side of the air-dissipative heat exchanger 140 furthest from the compressor 120. Figure 1 As shown. By stacking the air radiator heat exchanger 140 and the condenser 130, the structure of the water chiller can be optimized, increasing functionality while optimizing the space utilization on the main body 100 of the water chiller.

[0034] Furthermore, the water chiller body 100 includes an indoor side 101 and an outdoor side 102, the fan 110 is installed on the outdoor side 102, the condenser 130 is located on the indoor side 101 and is arranged corresponding to the fan 110, and the air radiator heat exchanger 140 is located between the fan 110 and the condenser 130.

[0035] Specifically, the main body 100 of the water chiller has an indoor side 101 and an outdoor side 102 on opposite sides. After installation, the indoor side 101 faces indoors, and the outdoor side 102 faces outdoors. The fan 110 is installed on the outdoor side 102 of the main body 100, and the condenser 130 is installed on the indoor side 101 of the main body 100, corresponding to the position of the fan 110, so that the condenser 130 can exchange heat with the refrigerant through the fan 110. The air radiator heat exchanger 140 is located between the condenser 130 and the fan 110. While integrating the air radiator heat exchange function, it saves space occupied by the main body 100 of the water chiller by sharing the fan 110 with the condenser 130.

[0036] Furthermore, the output end of the compressor 120 is connected to the input end of the condenser 130 through the refrigerant passage 200, and a dehumidifying evaporator 160 is connected between the input end of the compressor 120 and the output end of the condenser 130. The dehumidifying evaporator 160 is located on the indoor side 101.

[0037] Specifically, the main body 100 of the water chiller also integrates a dehumidifying evaporator 160, giving the water chiller a dehumidification function. The dehumidifying evaporator 160 is located between the compressor 120 and its input end and the condenser 130's output end. The dehumidifying evaporator 160 is connected to the refrigerant passage 200 via a separate pipeline, and thus connected to the compressor 120's input end and the condenser 130's output end. The low-temperature refrigerant discharged from the condenser 130 becomes gaseous in the dehumidifying evaporator 160. The heat in the air is transferred to the refrigerant through contact between the air and the surface of the dehumidifying evaporator 160, thereby causing the water vapor in the air to condense into a liquid state, achieving the dehumidification effect.

[0038] Furthermore, a first electronic expansion valve 170 is provided between the output end of the dehumidifying evaporator 160 and the condenser 130.

[0039] Specifically, the first electronic expansion valve 170 is located on a separate pipeline connected to the dehumidifying evaporator 160. By adjusting the first electronic expansion valve 170, the refrigerant is throttled so that the refrigerant changes from a liquid state to a gaseous state and enters the dehumidifying evaporator 160.

[0040] Furthermore, a dryer filter 180 is also provided on the refrigerant passage 200, and the dryer filter 180 is connected between the output end of the condenser 130 and the first electronic expansion valve 170.

[0041] Specifically, the dryer filter 180 is located on the refrigerant passage 200 at the rear end of the output end of the condenser 130, and the dryer filter 180 is located at the front end of the first electronic expansion valve 170. The dryer filter 180 is used to remove water vapor and impurities from the refrigerant.

[0042] Furthermore, a second electronic expansion valve 190 is also provided on the refrigerant passage 200, which is used to regulate the refrigerant flow rate.

[0043] Specifically, the second electronic expansion valve 190 is located on the refrigerant passage 200 between the dryer filter 180 and the first outlet. By adjusting the opening of the second electronic expansion valve 190, the flow rate of the refrigerant can be controlled, thereby adjusting the heat exchange efficiency of the water chiller.

[0044] Furthermore, a first circulation pump 310 is provided on the first circulation water passage 300, and a second circulation pump 410 is provided on the second circulation water passage 400.

[0045] Specifically, the first circulation pump 310 is connected to the first circulating water passage 300, and the first circulation pump 310 is used to circulate the circulating water in the first circulating water passage 300. The second circulation pump 410 is connected to the second circulating water passage 400, and the second circulation pump 410 is used to circulate the circulating water in the second circulating water passage 400.

[0046] Furthermore, it also includes an electrical control module 500, which is located on the indoor side 101 and is electrically connected to the fan 110, compressor 120, first electronic expansion valve 170, second electronic expansion valve 190, first circulation pump 310 and second circulation pump 410.

[0047] Specifically, the electronic control module 500 is used to control the opening, closing, and speed of the fan 110, adjusting the heat exchange efficiency of the air-dissipative heat exchanger 140 and the condenser 130 by adjusting the speed of the fan 110. The electronic control module 500 is also used to control the opening, closing, and degree of the first electronic expansion valve 170 and the second electronic expansion valve 190. By adjusting the opening of the first electronic expansion valve 170, the refrigerant entering the dehumidifying evaporator 160 is throttled, thereby causing the refrigerant to vaporize. By adjusting the opening of the second electronic expansion valve 190, the flow rate of refrigerant in the refrigerant passage 200 is regulated. The electronic control module 500 is also used to control the opening and closing of the first circulating pump 310 and the second circulating pump 410.
