1.2. Manufacturer and machine identifi cation
1.3. Machine description
This machine has been designed and built to be installed on vehicles
(motor homes, caravans, special vehicles, etc.) in order to improve
the internal temperature. When the weather is hot it supplies cool and
dehumidifi ed air; when the weather is cold it supplies hot air without
however replacing the vehicle’s original heating system. In both cases
the air temperature is adjustable.
Cool air - Description of operation (FIG. 5)
The system is composed of: compressor (A), condenser (B), evaporator
(D) a 4-way switchover valve (F) and the pressurized refrigerant.
The refrigerant, by changing physical state from liquid to gas, heats or
cools the components through which it passes.
The evaporator that has been made cold is crossed by the internal air
blown by the fan (C).
It comes out cooled and dehumidifi ed. This action protracted over time
creates a reduction in the temperature inside the vehicle.
Hot air - Description of operation (FIG. 5)
The refrigerating cycle is reversed by the 4-way valve switching over
(F); the internal coil changes from evaporator to condenser, thereby
heating the air passing through it.
The system is equipped with a heating element (E) that increases the
effi ciency of the heat pump at low temperatures.
