Composed of the freezing cylinder (evaporator), a
Copeland Scroll Compliant rotary compressor, a
high efficiency condenser, an economiser, a
thermostat valve and a number of minor accessories.
All these components are designed specifically for
operation at low temperatures using R22 or R404A
coolant gases.
Cooling is carried out by steam compression: the
compressor pumps gas into the condenser, where it
is cooled and liquefied, and the liquid gas then passes
through the thermostat valve and is vaporised in the
freezer cylinder (transforming into gaseous state once
more) before returning to the compressor and
starting the cycle again. Vaporisation of gas in the
freezing cylinder removes heat from the ice cream
mix, which cools down; the heat is then disposed of
3.1.4 Refrigerating plant
The electrical system consists of the operator panel
and the electrical panel which covers all of the rear
of the machine. The operator panel may be used to
activate or deactivate all machine functions, adjust
functions and indicate anomalies. The electrical box
at the rear contains the main switch and all control
and power devices.
3.1.5 Electrical system
in the condenser, where it is transferred to the water
in the tower (or well), heating it.
A pressure switch valve assembled on the condenser
water circuit keeps condensation pressure constant,
independently of water temperature.
The system mounted on the Frigus 600 is a
particularly efficient one which makes use of a
dependable, low maintenance Scroll Copeland
compressor which acts as a two-stage compressor
with an economiser to obtain considerable cooling
capacity and improved dependability.
