A refrigerator will store your food at the right temperature, to reduce spoilage and limit the growth of harmful bacteria. The process of refrigeration starts by distributing the warmth from the interior of the appliance to the exterior, relying on principles of evaporation and condensation.

The primary components of a refrigerator are below. For questions or service call A&L Appliance Repair:

Once the evaporator is not working, it’s time to enlist a professional. Do not wait too long.

Expansion Device

How Does Refrigeration Work?

1. Right when the temperature in the interior of a refrigerator goes above the set point sensors alert the compressor to begin, and then the next cooling period starts. The appliance draws in the cool liquified refrigerant, then condenses and pressurizes it, and increases the temperature, so it can turn into a gas form.

2. The refrigerator compressor directs the hot gas towards the condenser coils on the outside of the appliance, at which point it comes in contact with the lower temperature in the home and returns to a liquified form.

3. The cool liquified gas continues its journey towards the refrigerator evaporator, finding its way through the coils within the refrigerator and freezer.

4. The coolant then absorbs the warm air from the interior of the appliance, reducing the temperature back to the optimal final point.

5. The liquid then evaporates, and will return back to a gas form, and returns to the compressor unit to continue the cooling cycle.

Refrigeration is often used in several applications and large appliances, including heat pumps, air conditioners, refrigerators and residential freezers. By contracting warmth from one area and then transferring it to a different one the cycle of refrigeration aids in cooling your house, provides a safe space for perishable food, and also helps with manufacturing and storage of several different common products and goods.
