1. A method for cooling an enclosure comprising:

  • initiating a first phase of a first cooling cycle in the enclosure using an air conditioning system having a compressor, an evaporator coil and a fan adapted to pass air over the evaporator coil, the first phase including activation of the compressor and the fan;

    subsequent to the first phase, initiating a second phase of the first cooling cycle wherein the fan is activated and the compressor is not activated;

    measuring of one or more parameters during at least the second phase of the first cooling cycle; and

    altering a duration of a second phase of a subsequent cooling cycle based at least in part on the measurements during the first cooling cycle, wherein the duration of the second phase of the subsequent cooling cycle depends on an expected temperature drop that is based at least in part on a measured temperature drop during the second phase of the first cooling cycle.
