Expansion valves are devices used to control the refrigerant flow in a refrigeration system. They help to facilitate the change of higher pressure of liquid refrigerant in the condensing unit to lower pressure gas refrigerant in the evaporator.
The term “low side” is used to indicate the part of the system that operates under low pressure, in this case, the evaporator. Also, the “high side” is used to indicate the part of the system that operates under high pressure, in this case, the condenser.
There are basically four types of valves that are in use. These valves are also referred to as metering devices.
- Electronic Exp. Valves
- Thermostatic Exp. Valves
- Capillary Tubes
- Float Valves
