Claim 0:
1. A method of purging contaminants from a refrigerant of a heat pump via a purge system comprising:
generating a driving force across a separator;
providing refrigerant including contaminants to the separator;
separating the contaminants from the refrigerant within the separator;
monitoring one or more parameters of the purge system and the heat pump; and
actively controlling an operational parameter of the purge system in response to monitoring one or more parameters of the purge system and the heat pump;
wherein monitoring one or more parameters of the purge system and the heat pump includes at least one monitoring a rate of change of difference in pressure across the separator, monitoring an amount of contaminants within the refrigerant, and monitoring a difference in pressure across the separator
wherein if the difference in pressure across the separator is below a threshold, actively controlling an operational parameter of the purge system in response to monitoring the difference in pressure across the separator includes maintaining constant operation of the purge system.
