• A thermal expansion valve is a key element to a heat pump; the cycle that makes air conditioning, or air cooling, possible.
• A basic refrigeration cycle consists of four major elements, a compressor, a condenser, a metering device and an evaporator.
• Flow control, or metering, of the refrigerant is accomplished by use of a temperature sensing bulb, filled with a similar gas as in the system, that causes the valve to open against the spring pressure in the valve body as the temperature on the bulb increases.
