Abstract
An HVAC (Heating, ventilation and air-conditioning) system for a machine room enclosure monitors the cycle time between powered-on and powered off intervals of a temperature controlled environment in the enclosure. Activation of a cooling unit occurs based on a computed time for attaining a cooling satisfaction threshold and an idle time until cooling is again called for based on a cooling demand threshold. Activation is adjusted based on a duration of the cycle times to avoid an excessive duration or brevity that imposes a strain on the cooling unit. The cooling demand and satisfaction thresholds are adjusted up or down to moderate the activated and idle cycle time. Additional adjustments are made for aged equipment that may be less efficient and more susceptible to strain from excessive cycling, and for extreme ambient temperatures that impose a greater burden and which may require additional time for reducing enclosure temperature.
