Replacing Components in a Refrigeration Unit

When you are working with refrigeration units, there are many parts and components that can be in need of replacement. Replacing worn or broken parts is a more cost-effective option that replacing a whole unit. There are many different parts that may need to be replaced in order to prolong the life of your unit and keep it working properly.

Evaporator

An evaporator is the part of a refrigeration unit that takes the liquid chemical that is used to make the unit cold and turns it into a gas to more efficiently move it though the unit. In order to replace the evaporator, the unit must be pumped down, which means that all of the refrigerant (both liquid and gas) is sent into the condenser so that none of it is spilled into the air when the part is removed. Once this pumping down is complete, the evaporator can be removed and repaired or replaced.

Compressor

There are four different types of compressor currently available: reciprocating, rotary, scroll, and centrifugal. Whichever type you have, they mostly do that same thing. The compressor is responsible for taking the gaseous refrigerant from the evaporator and pushing it to other parts of the unit. Removing a compressor is a more in-depth process than with the evaporator. The system must be pumped down, valves must be opened, and other parts need to be removed before the compressor can come out. It is best to find exact instructions based on your model before you attempt to remove a compressor.

Compressor Valve Parts

Once your compressor is removed, you will be able to view and remove the compressor valves. The valves are the parts of a compressor that allow coolant to enter and exit the compressor. They are very important to the health of the compressor and the entire unit.  These are fairly simple to remove from the compressor and replace or repair.

When something goes wrong with a refrigeration unit, sometimes it is just because a part needs to be replaced. Replacing parts with either manufacturer models or third-party supplies is a great way to make sure your unit keeps working correctly longer.
