LRV Specifications 

Description
Flexible, cost effective and attractive - this low profile system maintains Thermo King's reputation for high performance and low maintenance cost.

The HVAC system is a hermetically sealed rooftop unit containing two TK/Copeland compliant scroll compressors operating in tandem. One compressor cycles off when needed, providing capacity control.

Air from the car enters the return air plenum where it mixes with fresh air. The mixed air then passes through the filters and evaporator coil where it is cooled and dehumidified before entering the blowers. The blowers pressurize and discharge the cooled air out from the bottom of the unit into the vehicle air distribution ducts.

Routine service is accomplished through the return air grille. For heavy maintenance, the units can be removed as a complete assembly. The modular system design is available in capacity ranges from 7 to 12 tons.

Controls :

Thermo King's microprocessor features solid state sensors and comes standard on the HVAC system.

A check valve is built into the scroll compressor to prevent refrigerant from flowing back to the compressor after shutdown. Circuit breakers and overload relays interrupt power to motors and heaters in the event of overload or short circuits. Current transformers are used to monitor (max./min.) amps to protect components during overload conditions.
