DESCRIPTION AND OPERATION OF THE APPLIANCE

2. 1

DESCRIPTION

The upright refrigerators are condensed air refrigerator units made up of:
• A condensing unit (outside cold storage room)
• An evaporating unit (inside cold storage room)
• A control panel (positioned on the condensing unit), (
• Defrosting is of the electric type and it is automatic (
• Condensation is air based.
2. 2

OPERATION

The upright refrigerators are refrigerator units which function by means of refrigerator compressor of the
airtight type. With air tight motion and alternative motion, powered by electricity (monophase or three phase)
and using as a refrigerant the fluid R404A / R134A
Principle of refrigerator operation cycle
In thermodynamics for the refrigerator cycle we intend the change of state which a certain body undergoes (for
example a refrigerating fluid). The passage of the refrigerating fluid from the liquid state to the gaseous state
takes place in the evaporator. Because this is an endothermic phenomenon, it needs heat which, when it
happens, is taken from the air which the evaporator comes into contact with. So, when coming out of the
evaporator, the vapours of the refrigerating fluid are sucked out by an air compressor and sent to the
condenser. If the latter takes away not only the heat that the gaseous refrigerating fluid has acquired during
the course of the evaporation (ENTALPIA DI EVAPORATION), but also the calorific equivalent of the
compression work, then the fluid returns to the liquid state.
Because liquefaction is an exothermic phenomenon, there is production of heat, which is disposed of through
air and through water.
The refrigerant fluid, leaving the condenser, passes through an expansion organ and returns to the evaporator,
thus completing the cycle.

PREARRANGEMENTS

3. 1

ILLUMINATION

The illumination of the area must conform with the POWER regulations of the country in which the equipment
is installed and must, in any case, guarantee good visibility at all points, it must not create dangerous
reflections and must allow for easy reading of the controls.
3. 2 VIBRATIONS
In conditions of use which comply with the indications for correct use, the vibrations are not enough to create
dangerous situations.
3. 3

EMISSION OF SOUND

The refrigerator unit is designed to reduce the level of noise at source . (
