Characteristics And Principle Of Operation; Characteristics; Principle Of Operation Of Refrigeration / Freezing Device - Igloo LUNA Instruction Manual

Note! Improper use of the heat pump may lead to electric shock.
In the process of designing and manufacturing the equipment, solutions were used to minimise the possibility of
risk to people and property. However, this does not eliminate all possible risks.
The following are some events beyond the manufacturer's control that may cause potential hazards to personal
health and property safety.
▶ Risks due to incorrect installation:
▶
Accumulation and leakage of condensate (damage to property, short circuit)
▶
Refrigerant leakage from the circuit (danger to health and life, damage to property)
▶
Fall of the unit installed on an unsuitable structure, unstable ground (danger to health and life, damage to
property)
▶ Risks due to incorrect transportation:
▶ Falling or overturning of the equipment being transported (danger to health and life, damage to property).
▶ Risks caused by incorrect electrical connection or connection to a faulty electrical system:
▶ Short circuit, fire, explosion, formation of toxic gases (danger to health and life, damage to property)
▶ Operating the unit without protective panels and covers in place
▶ Contact with moving, hot, pressurized or live elements (danger to health and life, damage to property)

CHARACTERISTICS AND PRINCIPLE OF OPERATION

2.1.

Characteristics

Refrigeration/ freezing devices are general-use equipment for storage and display of various foods, previously
cooled toadequate operation temperature, at ambient temperature +15ºC /+25ºC and relative humidity up to 60%.
All equipment manufactured by IGLOO is adapted to operation in a suitable climate zone and suitable emperature
class, according to PN EN ISO 23953.
The guaranteed temperature inside the equipment is given on the rating plate and in Technical Data.

Principle of operation of refrigeration / freezing device

Refrigeration and/or freezing equipment is used for food storage in an adequately cold temperature. A liquid
called coolant absorbs heat from the inside of equipment and flows through the evaporator which blown through
by fans (ventilated equipment – dynamic) or is not blown through by any fans (gravity equipment – static). The
fans, if any, are usually placed very close to the evaporator. The evaporator is the coldest place of the equipment.
Depending on equipment type, the evaporator can be placed in different places: on the equipment back, on the
ceiling, or on the equipment bottom. The cooled air from the evaporator flows through ducts and air outlets, and
then is sucked by air inlets. The process is cyclical.
Do not obstruct any ventilation openings in the equipment which could hinder the circulation of
cooled air.
The temperature in the equipment is controlled by a thermostat (temperature regulator) located on the control
panel. Its location varies depending on the equipment model and type (see Technical Data). The thermostat
activates the equipment unit when the temperature in the equipment rises, and deactivates when the temperature
drops too fast. The thermostat is an electronic controller which controls many parameters such as temperature,
automatic defrosting, alarm signalling, etc.
Each refrigeration/ freezing furniture must be adequately thermally insulated. If the equipment has night roller
blinds or plexiglas night covers, remember to use them. The outside heat flowing into the equipment makes the
unit activate more frequently and increases the electricity consumption.
