Types of Expansion Devices and When to Use Them | Hose Master

Many types of expansion devices are used in industrial applications. Why are they necessary? As piping systems heat and cool, they experience changes in length caused by thermal expansion and contraction. The amount of this thermal expansion depends on the length of the piping run, the temperature differential, and the alloy of the pipe. For example, a 100-foot run of carbon steel pipe will expand 1.82 inches in length when its temperature increases from 70 degrees F. to 300 degrees F.

Types of Expansion Devices - Ques10

An expansion device is another basic component of a refrigeration system. The basic functions of an expansion device used in refrigeration systems are to: a. Reduce pressure from condenser pressure to evaporator pressure, and. b.

AC Expansion Device from Discount AC Parts

AC Expansion Device. Cooling solution in your vehicle is taken by the air conditioning system. In the AC system the role of A/C expansion device is vital in varying the flow of refrigerant according to the cooling demands. The A/C expansion device responds to the temperature regulator in your vehicle and adjusts the flow of refrigerant throughout the system.

There are 2 places in a refrigeration system that change the pressure. One is the compressor which creates an increased pressure on the high side and the other is the expansion device which restricts flow to the low side. Here we will discuss the restrictor that controls refrigerant flow to the evaporator.

Expansion devices: An expansion device in a refrigeration system normally serves two purposes : •The thermodynamic fuction of expanding the liquid refrigerantfrom condenser pressure to evaporator pressure. •The control functions which may involve the supply of liquid to the evaporator at the rate at which it is evaporated.

The Thermal Expansion Valve is responsible for metering the correct amount of refrigerant to the evaporator. The thermostatic expansion valve (TXV) meters the refrigerant to the evaporator by using a thermal sensing element to monitor the superheat. This valve opens or closes in response to a thermal element.

What are the Different Types of Expansion Valves? | Linquip

A thermal expansion valve or thermostatic expansion valve (often abbreviated as TEV, TXV, or TX valve) is a device that controls the amount of refrigerant released into the evaporator and is intended to regulate the superheat of the vapor leaving the evaporator. Although often described as a “thermostatic” valve, an expansion valve does not regulate temperature; the temperature of the evaporator will vary with the evaporation pressure.

Expansion Valves - Air Conditioning Systems

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.
