7.STRUCTURE OF COOLING SYSTEM

The funtion for each part of system:

1.COMPRESSOR：

Compressing gas state refrigerant to be high
temperature-high pressure liquid

2.CONDENSATOR：

Releasing heat.Let high temperature refrigerant
releasing heat and become high pressure- regular
temperature state refrigerant.

3.STRAINER：

Straining impurities of water vapor in the Refrigeration
system, preventing capillary plugging

4.CAPILLARY：

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 pressure­regular temperature state refrigerant become low
temperature-low pressure gas state.)

5.EVAPORATOR：

Absorb heat.Refrigerant become gasification in the
evaporator.(low temperature-low pressure state)

6.OUTTER MOTOR When cooling funtion:
Exhausung heat air from condensator to out door.
When heating funtion:
Exhausung cool air from evaporator to out door.

7.INNER MOTOR: When cooling funtion: Inspire indoor air through
condensator to heat indoor air.

When heating funtion: Inspire indoor air through
evaporator to cool indoor air.

8. 4-WAY VALVE:

Exchange the direction of flow to refrigerant, the
eva

p

orator and condensator swa

p

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.

10.ELECTRIC CIRCUIT FIX

PROBLEM CAUSE HOW TO FIX IT

SHOW E1

1:room temperature sensor damage replace the sensor or call service center

SHOW E2

1:eva temperature sensor damage replace the sensor or call service center

WITHOUT ACTION

1:without power supply check power and plug connect on or not
2:without power into transformer check power fuse connect or not
3:without power out from transformer transformer damage,replace it
4:without power out from 7805 replace 7805 (mark on IC3)
