V. Principles of Operation

Kooltronic Air Conditioners are required when the equipment operating temperature must be kept near
or lower than the ambient room temperature, and/or the cabinet must be sealed from dust, fumes, oil,
corrosives and other contaminants. This Air Conditioner utilizes a “Closed-Loop Cooling System” to
ensure optimum performance of the installed components.

Closed-Loop cooling seals the electronics enclosure from hostile elements in the environment. Two
separate circulation systems are employed. The internal system cools and dehumidifies the air inside
the cabinet, totally isolating the sensitive electronics and other components from the environment. The
external system uses circulating ambient air or water to discharge the heat removed from the
electronics. The heat is dissipated from the enclosure by means of the vapor compression refrigeration
cycle. This takes place in a hermetically-sealed refrigeration system, utilizing either an air-cooled or
water-cooled condenser heat exchanger. The warm air inside the enclosure is drawn through the
evaporator coil where it is cooled, dehumidified and returned.

Any enclosure moisture accumulated on the evaporator coil is collected in the condensate tray and
released to the ambient air through the drain tube or the condensate evaporator.

The heat removed through the evaporator coil is transferred by the compressed refrigerant to the
condenser coil. Ambient air or water is then passed through the condenser coil, where it absorbs the
heat and is then discharged to the environment.

The cool air discharge temperature is regulated by the capacity control (hot gas bypass) valve. The
unit is equipped with a Low Temperature Thermostat to prevent over-cooling. In applications having
frequent voluntary heat load fluctuations, an optional Compressor Short Cycle Protector is recommended.
