Parts of a Refrigerator

There are not many homes that don’t feature a refrigerator inside the kitchen. It’s been a must-own kitchen appliance for a lot of years. A residential refrigerator will store food and drinks at the right temperature, in order to prevent spoilage and stop harmful bacteria. The cycle of refrigeration starts by transferring the warmth from the inside of the appliance to the outside, using the principles of evaporation and condensation.

The primary components of your refrigerator are. For questions or service call H&H Denton Appliance Repair:


The compressor is both a pump and a motor, and it is necessary for the circulation of refrigerant in the system.
A compressor is a very important piece of a refrigerator. You should hire a professional service if the compressor is broken.


The condenser is found on the rear exterior wall of the refrigerator and helps to disperse the heat absorbed from inside the refrigerator then out in the surrounding air.


The evaporator is housed in the inside of the refrigerator where absorbs heat held inside of it, thereby lowering the temperature inside the unit.

Right when the evaporator stops working, it’s time to enlist a professional. Do not wait too long.

Expansion Device

Liquified refrigerant is carried within a capillary tube that serves as an expansion device to cool the gas inside, turning the gas back into a liquid.


The refrigerator thermostat exists to regulate the current temperature in the interior of a refrigerator, starting a new cooling period as appropriate.

A thermostat inside of a refrigerator is prone to problems. Troubleshoot and call a repairman in Denton for service the moment an issue occurs.

How Does Refrigeration Work?

1. Right when the temperature in the interior of a refrigerator rises higher than the set point sensors notify the compressor to engage, and then the cooling period begins. The refrigerator attracts the cold liquified refrigerant, then condenses and pressurizes it, and increases the temperature, in order to turn it into a gas form.

2. The refrigerator compressor guides the warm gas in the direction of the condenser coils located on the back of the appliance, where it comes into contact with the lower air temperature in the home and returns to a liquified state.

3. The cooled liquid continues its trip to the refrigerator evaporator component, traveling through the many coils in the interior of the appliance and freezer.

4. The refrigerant absorbs the heated air from within the refrigerator, lowering the temperature until it has reached the optimal final point.

5. The coolant evaporates, and will return back into a gas state, and then returns to the refrigerator compressor in order to continue the cooling cycle.

Refrigeration technology is found in several applications and large appliances, this includes heat pumps, air conditioners, refrigerators and freezers. By removing heat from one place and then transferring it to a different one the continuous cycle of refrigeration will help cooling your home, creates a perfect environment for perishable food, and also helps with the manufacturing and storage of a lot of different common products and materials.
