6. Air conditioner working principle

Cooling cycleLow temperature and low pressure refrigerant gas goes from evaporator,then be suction into compressor and compressed into high temperature and high pressure gas by

compressor and discharge to condenser; in condenser, the high temperature and high pressure gas

exchange heat with outdoor fresh air, then the gas becomes high temperature and high pressure

liquid; then it is cooled and decompressed by capillary and go into evaporator. In the evaporator, the

liquid refrigerant and gas refrigerant are mixed and evaporated, the heat which is demanded for

evaporation is supplied by indoor air, so the indoor air is cooled at the same time. Then the gas from

evaporator goes into compressor again, so the cooling cycle begins. And the cooled air is supplied

into air conditioning area through duct by fan.Heating cycle: The heating cycle is inverse cycle to cooling cycle. Four-way valve changes

its direction, so refrigerant change the direction. It means the high temperature and high pressure

refrigerant gas goes from compressor and into indoor heat exchanger, after the refrigerant is

condensed by condenser and throttled by capillary, it goes into outdoor heat exchanger and be

evaporated, then be suctioned by compressor again, so the heating cycle begins. And the warm air is

auto mode, the Auto word shall be displayed and the unit shall adjust its speed automatically according to the

ambient temperature.

When the unit operates under heat mode and the ambient temperature is low and humidity is high, frost shall

generate at the outdoor unit and the heating efficiency shall be decreased. When frosting happens, the unit shall

runs in defrost mode automatically, and Defrost word shall be displayed.

Note: The cooling only type unit does not have heat mode, and once the energy mode is set, the auto mode

shall be invalidated.
