Compressor Location Fundamentals (Indoor vs. Outdoor)

Indoor:

Indoor air-cooled condensing units in walk in coolers consist of a compressor motor and fan assembly that is mounted on a base plate. Condensing units make noise and give off heat—both of which can be objectionable depending on where they are located. Kitchen locations can be problematic to condensing units due to heat and grease over time. Compressors 1½ horsepower and above produce a significant amount of noise—they should be located either outdoors or in a basement. Another alternative is a water-cooled condensing unit; they are much quieter and greatly reduce heat output of the walk in cooler. However, since they use water for cooling, they can be very expensive to operate. Consequently, water-cooled condensing units are rarely used.

Outdoor:

Outdoor condensing units are pre-assembled and enclosed in a protective weatherhood. They contain all necessary controls to operate in an exposed, outdoor location. Outdoor condensing units also remove a big source of noise and heat load from your interior space. The walk in cooler will also operate more efficiently in colder weather. The initial cost of both equipment and installation will be somewhat higher, but there is a quick payback in efficiency and the atmosphere of your working environment.
