Abstract: In a refrigeration unit for use in cooling a space, such as a walk-in cold space, or other system, an easy access fan motor assembly is provided. A motor mount holds the motor with a plurality of legs that couple to a front panel using stud inserts. In some instances the legs are curved and looked like spider legs. A fan guard member covers the fan and is also attached to the stud inserts. By removing fasteners on the stud inserts, the guard member may be removed and the fan motor assembly may be removed from a position exterior to the refrigeration unit for repair or serving. Other systems and methods are disclosed.

Abstract: The present application provides a refrigeration system with a flow of refrigerant therein for a refrigerant mode or a defrost mode. The refrigeration system may include a four way valve, an evaporator in communication with the four way valve, a compressor in communication with the four way valve, and a condenser in communication with the four way valve. The four way valve directs the flow of refrigerant to the condenser in the refrigeration mode or to the evaporator in the defrost mode.
