Abstract
The present invention relates to a heat exchanger arrangement for use with an air conditioning system of the type comprising a condenser, an expansion device, an evaporator and a compressor connected in a refrigeration circuit filled with refrigerant. The heat exchanger arrangement comprises a collector arrangement for collecting condensate fluid that has condensed on the evaporator as condensate fluid. The heat exchanger arrangement also comprises a first heat exchanger configured for facilitating the transfer of heat from an airflow flowing to the condenser, to condensate received from the evaporator.
Claims20
A heat exchanger arrangement for use with an air conditioning system comprising a condenser, au expansion device, an evaporator and a compressor connected in a refrigeration circuit filled with refrigerant, the heat exchanger arrangement comprising:
- a collector arrangement for collecting condensate fluid that has condensed on the evaporator as condensate fluid;
- and a first heat exchanger, the first heat exchanger being configured for facilitating the transfer of heat from an airflow flowing to the condenser, to condensate received from the evaporator, wherein the heat exchanger arrangement comprises a second heat exchanger configured for facilitating the transfer of heat from refrigerant to condensate received from the evaporator, and wherein the second heat exchanger is located within a container of condensate which has passed through the first heat exchanger, the container being associated with, and located at an upper portion of, the first heat exchanger.
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.
An improved air-conditioning system comprising:
- a condenser;
- an expansion device;
- an evaporator;
- and a compressor, wherein the condenser, expansion device, evaporator, and compressor are connected in fluid communication in a refrigeration circuit filled with refrigerant;
- and wherein the improved air-conditioning system further includes a heat exchanger arrangement comprising:
- a first heat exchanger, the first heat exchanger being configured for facilitating the transfer of heat from an air flow flowing towards the condenser to condensate fluid received from the evaporator, wherein the heat exchanger arrangement comprises a second heat exchanger configured for facilitating the transfer of heat from refrigerant to condensate received from the evaporator, and wherein the second heat exchanger is located within a container of condensate which has passed through the first heat exchanger, the container being associated with, and located at an upper portion of, the first heat exchanger.
