Knowing When To Replace A Commercial Refrigerator Compressor in the Food Industry

 

The compressor is the heart of your refrigerator's operating system. For the proper functioning of the refrigeration cycle, the refrigerant must be compressed to the pressure corresponding to the saturation temperature higher than the temperature of the naturally available air or water. However, in the event that the refrigeration compressor is unable to reach the specific pressure required, a new compressor is needed. When looking for a new refrigeration compressor, take into consideration the various types, as well as the cost it takes to buy a brand new compressor. Equipment Exchange offers an affordable solution to replacing a refrigerator compressor that is no-longer-useable. We buy and sell quality used and refurbished food processing equipment, making the purchase of a food processing equipment less of a monetary deficient, while maintaining high-quality equipment needed in the food industry. 

What Happens When a Compressor Reaches the End of its Life-Span?  

Refrigeration compressors are used to increase the pressure and temperature of refrigerant and help in liberating the heat that is gained in the evaporator, releasing it into the atmosphere. As refrigeration compressors near the end of their life-span, three common things tend to happen:

  1. The compressor is running continuously

  2. The refrigerator trips the circuit breaker

  3. The refrigerator is running loudly

The Compressor is Running Continuously

One of the most common signs that the refrigerator's compressor is near the end, is when it begins running constantly. This happens when the compressor is unable to reach the needed pressure for cooling and other operating temperatures. This may be from not having enough refrigerant in the system, or the compressor's valves may be failing and will need to be replaced.

The Refrigerator Trips the Circuit Breaker

A refrigerator that trips a circuit breaker often, especially when starting up, is another sign that the compressor is beginning to fail. As the compressor ages, it takes an increasingly longer period of time to reach operating speed than a well-working compressor. Increasing time prolongs the period of inrush current, otherwise known as surge-on current, that can cause breakers to trip.

The Refrigerator is Running Loudly

Noise often accompanies a failing compressor. When the bearings start failing, the noise is usually combined with an increase in current draw, causing circuit breakers to trip. A compressor with failing bearings will also run hot, and give off a hot oily smell resulting from overheated wiring. When the valves cause the noise, it is usually from failure to cool properly.


New or Used Refrigeration Compressors for the Food Processing Industry?

 

With the increasing need for refrigeration, compressors are being developed in vast amounts and with “newer” and “better” technology. However, the basics of a refrigerator compressor remain the same. With so many refrigeration compressor types available, selecting the right one for your application can be overwhelming. Each compressor uses a different method to pressurize the refrigerant, but there are other differences which depend on the application, location, ambient conditions, etc. Some factors to consider for the best refrigerator compressor are:

  • Cost

  • Operating efficiency

  • Field serviceability

  • Availability of spares

  • Maintenance
