Unit Description
Introduction
The Thermo King V-520 10/20 and V-520 MAX truck
refrigeration systems are two piece units. The unit is designed
for medium-sized trucks and vans carrying fresh produce and
frozen and deep frozen goods.
The condenser is mounted on the front of the truck box or
container. The evaporator is mounted on the cargo
compartment ceiling. The main compressor is powered by the
vehicle engine via a belt. The unit is connected to the
compressor by refrigeration hoses. In electric standby
operation models, the second compressor is driven by an
elecric motor.
Control circuits operate on 12 and 24 VDC supplied by the
truck batteries for over-the-road operation. The refrigeration
system is protected by a high pressure cutout and a low
pressure cutout.
The operating mode is selected automatically: When the unit is
connected to an electric power source, engine-driven operation
is automatically blocked. If the vehicle engine is started up
while the power cable is still connected to the electric power
source, the unit will continue to operate in electric standby
mode. It is not possible to start the engine-driven compressor
until the power cable is disconnected from the unit.
There are two basic models:
• Model 10: Cool and defrost on truck engine driven
compressor operation.
• Model 20: Cool and defrost on both truck engine driven
compressor operation and electric standby compressor
operation.
• Model 30: Cool, heat and defrost on truck engine driven
compressor operation.
• Model 50: Cool, heat and defrost on both truck engine
driven compressor operation and electric standby
compressor operation.
