Electric Air Cooled Condensing Units for Refrigeration Circuit

A complete refrigeration circuit includes four main elements: compressor, condenser, throttle device and evaporator. The compressor compresses the refrigerant to a high saturation pressure and feeds it to the condenser for further cooling and condensation. The excess heat of condensation is released into the surrounding air. The liquid refrigerant leaving the condenser passes through the expansion valve and is fed into the evaporator, where it evaporates, removing heat from the environment. Often the main components of a refrigeration system are manufactured as separate units: the condensing unit and the air- cooling unit (unit cooler). The condensing unit consists of a compressor, condenser coil and fan motor, connected by pipelines into one system on a mounting plate or in a closed casing. The operation of the condensing unit is carried out from the controls panel. An air-cooling unit (unit cooler) consists of an evaporator coil, fan motor, electric panel, controls and optional electric heaters for defrosting, throttle valve etc.
