Ingersoll-Rand Thermo King V-520 MAX 30 User Manual

Unit Description
17
Refrigeration System
Refrigeration hoses or lines are used to connect the condenser,
the evaporator, the compressor and any other components.
Model 20 units have another compressor and an electric motor
mounted in the condenser section for electric standby
operation.
The engine compressor is driven by a belt from the engine. The
electric standby compressor is connected in parallel with the
engine-driven compressor. The standby compressor is
hermetically sealed with its electric motor. Both compressors
use the same refrigeration system circuit. Check valves isolate
one compressor from the other during operation.
Compressor operation is controlled by the thermostat, which
energizes the compressor clutch during engine operation or
starts the electric motor and energizes the compressor clutch on
electric standby operation. The refrigeration system is
protected by a high pressure cutout switch and a low pressure
cutout switch.
When plugged into standby power, engine operation is
automatically locked out. If the truck engine is turned on while
the power cord is still plugged into a power receptacle, the unit
will remain working in electric mode; the engine driven
compressor cannot be started until the power cord is unplugged
from the unit as the selection of engine operation or standby
operation is automatic.
