The connection of the compressor evaporator condenser and the connection of the pipe
The compressor presses the low-pressure refrigerant into a high-pressure refrigerant, then enters the condenser for cooling, then filters out the amount of water in the refrigerant, adjusts it to the evaporator through the expansion valve, then passes through the low-pressure pipe and returns to the compressor
The evaporator is between the compressor and the low pressure pipe, the feel is cold, and thicker because of the low pressure gas passing through;
The condenser to the expansion valve is essentially a liquid refrigerant; the expansion valve to the evaporator is a liquid refrigerant with a slight amount of air bubbles
Between the compressor and the condenser is a high-pressure gas, feel hot, and smaller, through the high-pressure gas;
