What is a Expansion valve

it is a device used in mechanical refrigeration system or Vapour compression refrigeration system. which controls the flow of liquid Refrigerant or Gas in the system. it's Supplies the liquid Refrigerant to Evaporator in desired quantity.

How does the expansion valve work

The Basic working principle of the, expansion valve or refrigerant control device receive liquid refrigerant or gas from the filter or Drier at higher pressure and normal temperature or medium temperature to Reduces the pressure and temperature of the liquid refrigerant (due to small or micro hole inside of the expansion valve). Then low pressure and low temperature liquid refrigerant to the Evaporator.

Installed of the Expansion valve

The Expansion valve or refrigerant control device Installed of the, between filter or drier and Evaporator. the Drier outlet pipe are connected to the expansion valve inlet pipe and The expansion valve outlet pipe are connected to the Evaporator inlet pipe. The vapour compression refrigeration system Or mechanical compression refrigeration system.

Where is the Expansion valve used

Use Or application of the, Expansion valve or refrigerant control device is both domestic and commercial refrigeration and air conditioning system, HVAC system's. Central air conditioning system, large air conditioning plants.

Types of the expansion valve

There are seven types of refrigerant control device

. Capillary Tube

. Thermostatic expansion valve

. Automatic expansion valve

. High side float valve

. Low side float valve

. Hand operating expansion valve

. Electronics expansion valve

. other one solenoid valve

Domestically used Expansion valves

The Domestic or house hold used expansion valves like a, generally used in Capillary Tube. For Example, house hold refrigerators, water ,bottle coolers, deep freezers, visible coolers, split, window air conditioner, heat pumps etc.

. Automatic expansion valve is depends upon the capacity of machine.

Commercial used expansion valves

The commercially or industrially used in expansion valves or refrigerant control devices like a
