The refrigerant gas flows to the compressor, which raises the pressure and temperature of the gas. It

then moves to the condenser coil where it is cooled and condensed by exchanging heat with the outside

air. The liquid refrigerant then flows through an expansion valve where the pressure is reduced and then

returns to the evaporator coil.

Outdoor air is drawn through the condenser coil, which is at the face of the outside enclosure. After

passing through the coil, the air is exhausted through the top of the enclosure.

Operation is controlled by the unit controller, which starts the compressor. The refrigeration system is

protected by high pressure and low pressure cutout switches.

The unit controller, located in the control panel enclosure, includes a keypad for entering control

commands and a display that provides system operating information to the operator.
