Brief Description of Control Principle
HTE21/HTQ21 are forced air-cooling refrigerators with two doors. A mechanical type
of all the control is generally adopted. The thermostat directly controls the start and
stop of compressor, and hence the refrigerator temperature.
Low Temperature Compensation in the above schematic diagram. When the ambient
is below the set temperature, the switch will be closed and the heating will work,
thus ensuring the normal start, and operation of refrigerator at lower ambient
temperature, in such case, the freezer compartment temperature can reach a good
point.
