However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be more thorough and complete.
[0029] This utility model provides an integrated liquid-cooled electric air conditioner that reuses condensate, which can solve the problem of resource waste caused by direct discharge of condensate in related technologies.
[0030] See Figure 1 As shown in the figure, an integrated liquid-cooled electric air conditioner for condensate reuse provided in this utility model embodiment mainly includes: an evaporator assembly 1, a condenser assembly 2, a vehicle-mounted high-pressure hose 4 and a vehicle-mounted low-pressure hose 3; the air conditioning system includes a heating and cooling system, a battery liquid cooling system and a condensate reuse system.
[0031] For details, see Figures 2-6 As shown, the air conditioning heating and cooling system includes a condenser assembly 2 and an evaporator assembly 1. The condenser assembly 2 includes a compressor 211, a four-way reversing valve 213, a condenser 28, a dryer filter 210, an expansion valve, a gas-liquid separator 214, a condenser fan 26, and a connecting pipe 29. The connecting pipe 29 also includes a high-pressure switch 218, a low-pressure switch 217, a high-pressure charging valve, a low-pressure charging valve, a high-pressure vibration damping hose 225, and a low-pressure vibration damping hose 226. The evaporator assembly 1 includes an evaporator 17 and an evaporator fan 14.
[0032] The condenser assembly 2 is connected to the evaporator assembly 1. The condenser assembly 2 includes a first plate heat exchanger 220, which has at least two flow channels. One flow channel is connected to the vehicle's liquid cooling system, and the other flow channel is connected to the condensate drain outlet 13 at the evaporator end. The condenser assembly 2 also includes a second plate heat exchanger 219 and a compressor 211. The second plate heat exchanger 219 has at least two flow channels, one of which is connected to the vehicle's liquid cooling system, and the other flow channel is connected to the compressor 211. The condenser assembly 2 has a battery coolant inlet 24 and a battery coolant outlet 25 for connection to the vehicle's battery water cooling system. The battery coolant inlet 24 and the battery coolant outlet 25 are connected to the first plate heat exchanger 220 and the second plate heat exchanger 219. The battery coolant inlet 24, the first plate heat exchanger 220, the second plate heat exchanger 219, and the battery coolant outlet 25 are connected in sequence.
[0033] This air conditioner is a split-type air conditioner. The evaporator assembly 1 is generally installed on the ceiling inside the vehicle, and the condenser assembly 2 is installed on the vehicle chassis. The two are connected by high / low mounting hoses to form the entire air conditioning heating and cooling system.
[0034] See Figure 1 and Figure 2 As shown, the air conditioning refrigeration principle is as follows: After the refrigerant passes through the compressor 211, it becomes a high-temperature, high-pressure gaseous refrigerant, which is discharged from the compressor exhaust port and flows directly into the condenser 28 through a shock-absorbing metal hose. Here, through the condenser fan 26, the refrigerant undergoes air-cooled heat exchange in the condenser 28, condensing into a medium-temperature liquid refrigerant. It then passes through the dryer filter 210 to remove any possible water vapor. Next, after passing through the expansion valve, the refrigerant becomes a low-temperature, low-pressure liquid refrigerant. In the evaporator 17, through air-cooled heat exchange with the evaporator fan 14, the refrigerant evaporates and absorbs heat, becoming a gaseous refrigerant. It then flows through the gas-liquid separator 214 for gas-liquid separation, and the completely gaseous refrigerant returns to the compressor suction end.
[0035] Air conditioning heating principle: After being discharged from the compressor 211, the refrigerant becomes a high-temperature, high-pressure gaseous refrigerant. After passing through the four-way reversing valve 213, it flows into the evaporator 17. At this time, the high-temperature refrigerant undergoes air-cooled heat exchange with the air. The hot air is driven by the evaporator fan 14 to enter the vehicle through the air outlet. The cooled refrigerant then passes through the expansion valve, the dryer filter 210, and the condenser 28 in sequence, and finally flows back to the gas-liquid separator 214 to enter the compressor suction end.
[0036] See Figure 2 and Figure 4As shown, the battery liquid cooling system includes a liquid cooling expansion valve 216, a second plate heat exchanger 219, a first plate heat exchanger 220, a coolant connection pipe 227, a battery coolant inlet 24, and a battery coolant outlet 25. The battery coolant inlet 24 and the battery coolant outlet 25 are respectively connected to the vehicle battery water cooling system; the vehicle coolant flows from the inlet through the coolant connection pipe 227 to the liquid cooling pipes of the first plate heat exchanger 220 and the second plate heat exchanger 219, and then flows back to the outlet to enter the vehicle liquid cooling system. The entire circulation system is powered by the vehicle water pump.
[0037] Battery cooling principle: The second plate heat exchanger 219 is equipped with refrigeration pipes and liquid cooling pipes. The high-temperature coolant from the vehicle's battery water cooling system enters the liquid cooling pipes of the second plate heat exchanger 219, where it exchanges heat with the low-temperature refrigerant through wall-to-wall contact. The low-temperature coolant then flows back into the vehicle's battery water cooling system, where it exchanges heat with the battery surface. Simultaneously, under the action of the vehicle's water pump, the coolant circulates repeatedly throughout the liquid cooling system, thereby achieving the purpose of cooling the battery.
[0038] See Figure 2 As shown, the principle of the condensate reuse system is as follows: When the air conditioner is in cooling mode, a large amount of low-temperature condensate will be generated on the surface of the evaporator 17 and will flow out through the drain pipe of the evaporator assembly. This condensate will be collected in the water tank 222 through a water pipe. The water tank 222 is also equipped with a water level sensor. When the condensate accumulates to a certain amount, the water pump 221 will be turned on, and the condensate will flow into the water pipe of the first plate heat exchanger 220. In the first plate heat exchanger 220, it will exchange heat with the high-temperature coolant flowing through it, thus achieving the purpose of reuse. Finally, it will be discharged through the drain outlet. The drain outlet is also equipped with a water pipe solenoid valve, which can be used to block the drain outlet when no condensate is generated.
