Operation mechanism

Cooling cycle

Connected with pipes,indoor unit and outdoor unit form a refrigeration system.With power,compressor takes in
low temp.and low pressure refrigerant vapour from evaporator of indoor unit,presses it into high temp.and high
pressure gas,then discharges it into condenser of outdoor unit.By help of axialflow fan,heat is removed to outdoor
air from the gas which then condenses into liquid.After capillary tube throtting,the liquid drops temp.and pressure,
flows into evaporator.There,by help of cross-flow fan,the liquid absorbs heat from room air,evaporates and
becomes low pressure vapour which then flows into compressor again,beginning next cooling cycle.Therefore,

heat is transfered from indoor to outdoor,and room gets cool.

Ventilation cycle

Ventilation cycle divides into indoor and outdoor two parts.With suction of cross-flow fan,room air flows through
filters,exchanges heat in evaporator,then returns to room.In this way,room air can be cool and dehumidified.At
the same time,pumped by axial-flow fan,outdoor air flows through condenser and exchanges heat.

Heating cycle

Heat pump type air conditioner uses a commutator (4-way electromagnetic valve) to change refrigerant flow
direction.When heating,refrigerant firstly enters indoor heat-exchanger,releasing heat and condensing.Then it
enters outdoor heat-exchanger,absorbing heat and evaporating.Because consumption power changes into heat
which is discharged in room,heating efficiency is very good.

Smell

Sometimes there is some smell out
of indoor unit,as does not mean any
machine failure,but because of
suction air mixed with smell of
furniture or smoking etc.

Important notices

Do not cut or pull strongly power
lines and connecting lines.

Close doors and windows
(better using contains)while
operating air conditioner,to
avoid cool or heat leakage
which affects air condition.
If room air is quite turbid,you
should open a door or
window a little for a
moment to get some outdoor
fresh air.

It is only specific technician who can operate the stop valve of outdoor unit,otherwise it is possible to make refrigerant leak
out and compressor breakdown.

Air Conditioner should be
operated with stable voltage
in range of 198-253

V

1Ph,
otherwise, compressor
would vibrate terribly to
damage refrigeration
system.

Do not insert any foreign
materials into the air inlet
or air outlet, it is very
dangerous.

Delay operation

To avoid action of overload protector
or other security devices,we design a
delay for 3

4 minutes before starting
cooling or heating or dehumidifying
cycle in following situations:

To start again immediatelly after

stopping;

To adjust operation mode.

Electric circuit
