High-voltage switch - after the refrigerant pressure in the system rises to a
certain value, high-voltage switching operation, the alarm is transmitted to
the controller.
High pressure sensor - detecting high side pressure of the refrigeration
system, and transmitted to the controller.
Filter drier - protection refrigeration systems, water filtration systems, solid
acid and impurities.
The expansion valve - valve electronic expansion valve, the refrigerant flow
rate regulator.
Evaporator - refrigerant evaporated inside the evaporator absorbs heat, gas
flow through the outer surface of the evaporator heat absorber is cooled.
Low pressure sensor - the low-pressure side refrigerant pressure detecting
system, and transmitted to the controller.
Fan - means for driving an air flow through the air conditioning cycle.
Controller - logic control center of the machine, the operation of the
automatic control equipment, alarms, details refer to the section controller.
Located outside the electrical box.
Touch screen - computer interaction window, only to see the equipment
