| description | Embodiments of the present disclosure are directed toward purge units of vapor compression systems, and methods of control thereof, that selectively activate and deactivate the purge unit in response to one or more conditions to, for example, control refrigerant-to-air ratios while still minimizing the durations of the purge cycles. For example, in certain embodiments, these conditions may include conditions within the chiller condenser, time since last purge activation, time since last venting of non-condensables, and combinations thereof. By reducing an amount of time that the purge unit would be active without removing a substantial amount non-condensables from the vapor compression system, present embodiments reduce the power consumption of the purge unit, as well as the vapor compression system as a whole, while still being responsive to prevent or mitigate a loss of efficiency due to a substantial accumulation of non-condensables in the condenser of the vapor compression system. |
