Parallel Compressor Systems feature multiple compressors that all work together to suffice refrigerated loads.  This type

of system is applied to many different applications, the most

common are supermarkets, large refrigerated warehouse space, cold storage & distribution centers, and food

processing facilities.

 

Parallel Systems or “Racks” provide huge incentives

over alternative refrigeration methods.  The most notable

advantages are:

 

Energy Efficiency-  By using multiple compressors and

computer optimization, the compressors cycle on and off to continuously match the exact cooling requirements.  Therefore compressors are not forced to run only to maintain a working pressure.  Several other factors help reduce energy

consumption when using parallel systems, for example–

condenser fan cycling, compressor unloading, lower year round head pressure,  and hot gas defrost.

 

Compressor Redundancy–  Through the use of multiple compressors all working together to maintain the load, a

certain degree of redundancy is created.  If a compressor

failure occurred, there are additional compressors to distribute the load which provides minimal deviation from design

temperature.  The degree of redundancy can be specified

to a point where no temperature deviation occurs.

 

Flexibility– Systems are custom designed to match the

exact requirements of the customer.  Moreover, thru flexibility of compressor staging and computer controls future load

additions or temperature changes can be accommodated.
