Classification: CPC F  B  Y | IPC B  F

Claim 14:
15. A heat pump comprising:
a vapor compression loop;
a purge system in communication with the vapor compression loop, the purge system including a separator operable to separate contaminants from a refrigerant purge gas provided from the vapor compression loop;
a sensor for monitoring one or more parameters of the purge system and the vapor compression loop; and
a controller connected to the sensor, the controller being operable to actively control at least one operational parameter of the purge system in response to data provided by the sensor;
wherein the sensor is operable to monitor at least one a rate of change of difference in pressure across the separator, an amount of contaminants within the refrigerant, a difference in pressure across the separator;
wherein if the difference in pressure across the separator is below a threshold, an operational parameter is controlled to maintain a constant operation of the purge system.
