The Carrier 48TF660002 Heat exchanger, an essential element of different types of HVAC equipment. It is used for changing thermal energy from one fluid to another – most commonly, air to refrigerant. During the heating mode, low-pressure refrigerant gas flows through the heat exchanger and releases heat to the surrounding air and then is circulated throughout the building. During cooling, the process is in the reverse warm indoor air flows across the heat exchanger and relinquishes heat to cooler refrigerant gas, for refrigerated air distribution.
How to install an expansion valve for refrigeration?
Thermostatic expansion valves are an integral part of your refrigeration unit. They are responsible for ensuring the right dosage of refrigerant is entering the cooling coil to ensure maximum efficiency in the air conditioning of the system.
These special expansion valves come with a temperature sensor that is mounted at the end of the evaporator coil. They incorporate signals from this sensor to maintain the required temperature of the HVAC system. The thermostatic expansion valve works like a precision device that can regulate the measurements of the liquid refrigerant that flows into the evaporator of your system. This regulation in the flow of the refrigerant is essential to prevent the reverse flow of the refrigerant into the compressor of your system.
Through this mechanism, the thermostatic expansion valve successfully separates the high and low pressure sides of the refrigeration/air conditioning system. The liquid refrigerant enters the expansion ...
