Abstract
Disclosed is an improved air conditioning system of the type having a refrigerant which sequentially flows through compressor means, condenser means in heat exchange relationship with outdoor air, expansion means, and evaporator means for the direct or indirect cooling of air in a confined space for maintaining the confined air space at a desired set point of temperature and/or humidity. The improvement for maintaining said set point of temperature and/or humidity of the confined space at variable heat loads therein and at variable outdoor air temperature comprises variable speed compressor means responsive to varying outdoor air temperature for attenuating refrigerant mass flow corresponding to lower outdoor air temperature; and expansion means responsive to attenuated refrigerant mass flow for maintaining adequate refrigerant mass flow to the evaporator means for maintaining constant the desired set point of temperature and/or humidity of the confined space at varying outdoor air temperature.
