Refrigerators in public administrations are
known as "hot iron". How much equipment drones away to
itself is mostly unknown, that many an employee have put
their old fridge from home unannounced in their offices in
order to cool a couple of drinks.
Because of this, we have no idea how much
effect such semi-official equipment has on the energy bill.
These old appliances often feature poorly fitting seals and
are often considerably less efficient than their more modern
equivalents |
The influence of the temperature in the
room where the refrigerator is installed
The influence of the temperature in the
room where the refrigerator is installed Refrigerator operation is
optimal for the temperature range specified by the manufacturer.
Outside of the specified temperature range the refrigerant
condensation-evaporation cycle is not ideal.
Some models struggle to maintain their
interior compartments at the right temperature when the room
temperature is high (refrigerator energy consumption is 38% higher
for an ambient air temperature of 23oC when compared with a
temperature of 18oC). It is, therefore, important to install your
refrigerator at the right place in a room: try to avoid any heating
source, direct sunlight or poorly ventilated areas.
Switch off your refrigerator when you
go on holidays
Running an almost empty refrigerator is
not energy efficient. Save energy and switch it off when you don't
need it.
If you do turn it off, do not forget to
leave the refrigerator door open to prevent mould growth.
Cleaning of the freezer
Sometimes, frost forms in the freezer
compartment. This causes bad convection between the evaporator and
the air in the freezer and reduces the efficiency of the
refrigerator. You should defrost the appliance occasionally in order
to reduce energy consumption . A refrigerator with a five centimetre
thickness of ice consumes double the energy of refrigerator without
frost.
It's essential to clean the back of the
refrigerator where the condenser is located in order to maintain
efficiency.
Do not leave the door open a long time
Because the aim of a refrigerator is to
cool food, you mustn't warm the inside compartment with ambient air.
So when you want something from the
refrigerator, take it out quickly and close the door immediately.
Moreover you must keep in mind it's
better not to open the refrigerator many times. It's better to open
the refrigerator once and take out what you need, rather than
opening it many times.
