The compressor - the main role of the refrigeration system through the
evaporator for evaporating low pressure refrigerant gas compressed at room
temperature to a temperature high-pressure refrigerant gas, increasing its
temperature of condensation, into the condenser (outdoor unit) is
condensed to a liquid. The key is the core component of the refrigeration
system.
High-pressure switch - after the refrigerant pressure in the system rises to a
certain value, high-pressure 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.
