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.
