In an air conditioning system which comprises a compressor to compress a refrigerant, a condenser to remove heat from the refrigerant and condense it, and an evaporator to evaporate the refrigerant for recycle to the compressor, the improvement which comprises a peak shaving system comprising: (a) means for storing a medium from which heat can be extracted and in which heat can be stored, (b) a first control valve for optionally diverting the flow of the refrigerant from the condenser to the first expansion valve and into the evaporator or directing the refrigerant instead to the storage means, (c) a second control valve for optionally directing the flow of the refrigerant from the first control valve through a second expansion valve before the refrigerant reaches the storage means or bypassing the second expansion valve, and (d) a third constant valve for optionally directing the flow of the refrigerant from the storage means to the compressor or through a third expansion valve to the evaporator.
