Compressor as a Condenser,

Either split or outdoor overall heat pump water heater, the evaporation temperature is very wide. In order to be effective within a wide range, it is recommended not to use a single capillary. Instead of using the expansion valve or a group of capillary, it will respond to changes in ambient temperature to ensure that in all operating conditions the machine has a suction superheat. While avoiding the liquid directly getting into the compressor, particularly in winter. Heat pump water temperature is above 55 degrees, with the use of proceeds, the tank temperature will drop immediately to about 45 degrees, the compressor will need to start the run, therefore compressor basically run in areas with high condensing temperature .

The condensation temperature is the main factor to affect the life of the compressor, the integrated load compressor suffered under the conditions of running the same time. The heat pump water heater is far higher than the air conditioning compressor. In winter operation of the compressor is hard, if the occurrence of breathing with liquid, the liquid refrigerant entering the compressor internal quickly lower the temperature of the compressor , coupled with the low ambient temperature, resulting in a bottom temperature of the compressor , which is very different from the part of a machine such as a cone crusher, will drop relatively low. The so-called compressor superheat degree is at the bottom of which is defined as: the temperature at the bottom of the compressor - the condensation temperature.

After the compressor stops working, the condenser is in the environment of the high water temperature, then the evaporator is gradually cooled, the temperature difference caused the refrigerant gradually migrate to the evaporator and compressor. If the value is zero or less than zero, it would be in the compressor as a condenser, the refrigerant will be slowly within the compressor housing and be condensed into liquid deposited in the...
