4.CAPILLARY：
5.EVAPORATOR： Absorb heat.Refrigerant become gasification in the
6.OUTTER MOTOR When cooling funtion:
7.INNER MOTOR: When cooling funtion: Inspire indoor air through
8. 4-WAY VALVE:
The thorey for cooling funtion：
Using compressor to compress refrigerant to be high temperature-high
pressure liquid and through condensator (Using Fan to exhaust the heat to
outdoor).Refrigerant entry capillary after cool and become low temperature
liquid state to flow in evaporator.Refrigerant become gasification in the
evaporator and absorb heat,the temperature of evaporator low.(Using Fan
to inspire indoor air through evaporator to cool indoor air) Compressor
insprie gas state refrigerant again. Repeat this cycle step reached indoor
cooling.
The thorey for heating funtion：
Using 4-way valve to swap the evaporator and condensator, blow hot air to
indoor and exhaust cool air to outdoor.
refrigerant become low temperature-low pressure gas
state after through capillary.(Capillary is a thin brass,
from small-diameter(Capillary) to large
diameter(evaporator),area increase,high pressure-
regular temperature state refrigerant become low
temperature-low pressure gas state.)
evaporator.(low temperature-low pressure state)
Exhausung heat air from condensator to out door.
When heating funtion:
Exhausung cool air from evaporator to out door.
condensator to heat indoor air.
When heating funtion: Inspire indoor air through
evaporator to cool indoor air.
Exchange the direction of flow to refrigerant, the
evaporator and condensator swap
