Abstract

A vapor compression system having a defrost cycle is disclosed. A compressor, a condenser, an evaporator, and an expansion valve connected in a closed refrigerant loop with at least one flow control device. The at least one flow control device may control the flow of refrigerant through the closed refrigerant loop. At least one sensor monitors a predetermined parameter of the closed refrigerant loop and at least one controller receives a signal from the at least one sensor. The at least one controller controls the position of the at least one flow control device. The at least one controller initiates a defrost cycle in the closed refrigerant loop by substantially actuating at least one of the at least one flow control device to provide refrigerant flow from the compressor to the evaporator for substantially preventing formation of frost on the evaporator.
