Claim 15:
16. A method of improving the efficiency of an air-conditioning system comprising a condenser, an expansion device, an evaporator and a compressor connected in a refrigeration circuit filled with refrigerant, the method comprising the steps of:
a. collecting chilled condensate from the evaporator in a collector arrangement;
b. guiding the condensate to a first heat exchanger whereby the condensate is used to cool an airflow cooling the condenser; and
c. guiding, the condensate to a second heat exchanger whereby the condensate is used to cool refrigerant in the refrigerant circuit and wherein the condensate guided to the second heat exchanger first passes through the first heat exchanger, the second heat exchanger being located within a container of condensate which has passed through the first beat exchanger, the container being associated with, and located at an upper portion of, the first heat exchanger.
