Refrigerant-handling precautions
Although hydrofluorocarbon refrigerants are classed as “safe”, you
should still observe certain precautions during the handling, installation
and maintenance of the trailer refrigeration unit. Liquid
hydrofluorocarbon refrigerants evaporate rapidly when released into
the atmosphere, and quickly ice up everything that they touch. Skin
contact can lead to severe, frostbite-like injury. Hydrofluorocarbon
refrigerants may produce toxic fumes if exposed to a naked flame or
an electrical spark. These fumes are severe respiratory irritants,
potentially capable of causing death.
2.4.1 First aid
In the event of frostbite, protect the affected area from further injuries,
avoiding contact with the refrigerant and additional measures.
Contact of refrigerant or refrigerant oil with the eyes: In case of
contact with the refrigerant or refrigerant oil, immediately flush eyes
with large amounts of water (for at least 15 minutes) and get prompt
medical attention.
Skin frostbite:
•Remove refrigerant-contaminated clothing and footwear.
•Thoroughly rinse off the refrigerant with abundant lukewarm water.
•DO NOT apply heat (e.g. by rubbing or with a hot-water bottle).
•Seek medical attention immediately. While you are waiting for help to
arrive, cover the affected area as loosely as possible with a large sterile
dressing.
Inhalation of refrigerant:
Seek medical attention immediately and bring the injured person into
the fresh air. Administer artificial respiration if required.
2.4.2 Environmental regulations
GOVI trailer refrigeration units are shipped with a suitable charge of
refrigerant R452A.
If you detect any fault in the refrigerant circuit, or signs of leakage
from the trailer refrigeration unit, have the device examined and
repaired by a qualified specialist. DO NOT allow refrigerant to escape
into the open air. Please read the safety instructions and hazard
warnings in section 2.3 Safety and hazard precautions,as well as
the manufacturer’s data sheet for the refrigerant R452A. Dispose of
defective refrigeration units and drained-off refrigerant in accordance
with applicable environmental regulations.

System description
Fig. 5-1 Functional diagram
The process is based on the cooling cycle principle: heat transfer
occurs by means of a refrigerant, which absorbs heat in the evaporator
and then releases it in the condenser. All this takes place within a
closed loop. The refrigerant is pressurized by an electrically-driven
compressor, fluidized in the condenser, atomized by means of a
throttle valve and evaporated in the evaporator. The evaporator is
located inside the refrigerated trailer, while the condenser on the
outside.
The trailer refrigeration unit is equipped with a forced-ventilated
condenser and evaporator, axial fans, and electronic temperature
control.
