Commercial Refrigeration Compressor Guide: How to Pick a Perfect Compressor

The right compressor is critically vital to boost energy efficiency. Also, it enhances the reliability of your entire refrigeration system. It’ll have a positive impact on operational expenses. Remember, less frequent compressor parts maintenance and low energy consumption can directly bring you huge savings. Each compressor is also created for specific refrigerants. So, the refrigerant type of the compressor is also a vital element. Read further to discover more.

Compressor Application Requirement

People have different needs for compressors. This is because food is kept at varying temperatures. For instance, fruits and vegetables are stored at different temperatures than fish or seafood. That means you need a compressor that can accommodate the temperature requirements of various applications.

Compressors with varying compression ratios are designed and created. That’s why you’ll find the likes of multi-stage and single-stage compressors.

The pressure system is another key consideration. A compressor pressure system can be low, medium, or high. High-pressure systems work perfectly at temperatures above 23oF. Low pressure is ideal for compressors that operate at temperatures below -4oF. Medium-pressure systems work in between low and high temperatures, like -4oF and 23oF.

Compressor Capacity

Want to choose the right compressor? Consider the refrigeration capacity. Compressor capacity is directly related to pressure and temperature. It varies depending on the refrigeration occupied volume. You can measure the refrigeration compressor capacity whether in CFM or CFH to verify it before you can make a purchase.

Motor efficiency is another key feature of a compressor. You can measure it in horsepower. Go for a compressor with a high horsepower rating. Also, consider a high starting torque motor for a compressor that starts with non-equalized pressure.

Compressor Type

Various types of compressors are available to pick from. You need to choose a type that perfectly matches your needs and requirements. The most popular compressor types are:

• Reciprocating hermetic: These compressors are small in size. They work perfectly in refrigeration equipment that needs less cooling capacity. These compressors combine the benefits of hermetic and reciprocating compressors.
• Fridge compressor: This compressor is small and simple and can be used for small display cabinets and freezers. It’s designed for freezers, refrigerators, etc.
• Horizontal compressor: This is simply a rotor compressor. Its low height is the main advantage. They’re ideal for height-constrained refrigeration systems like commercial display cabinets, RV air conditioners, refrigerated trucks, etc. A horizontal compressor can meet the requirements of refrigeration capacity of up to 3HP.

Additional types include centrifugal, screw, piston, scroll, rotary, and mini compressor.

From energy consumption indicators and noise level to cooling capacity and where to use it, numerous factors influence the choice of a compressor. Be sure to partner with the right compressor provider to take your refrigeration experience to the next level.
