Abstract
Abstract The present invention provides an energy conservation and utilization arrangement for use with an expansible refrigerant air conditioner including a refrigerant circuit with a compressor, refrigerant condensor and expansion means to selectively heat a reservoir of fluid, for example, the water used in a swimming pool where selector valve means are provided to selectively supply compressed refrigerant from the air conditioning unit compressor to heat exchange means to transfer heat from the refrigerant to the fluid to be heated, or to the condensor means associated with the air conditioner unit or, when it is desired to heat the fluid but not to provide cooling, to direct compressed refrigerant to the heat exchange means and then to a return conduit, where the return conduit includes refrigerant expansion means to expand the refrigerant means, second heat exchange means to heat the expanded refrigerant and conduit means to return the heated refrigerant to the selector valve means where the selector valve means is adapted to return the refrigerant to compressor means inlet.

Claim 1
Independent Claim
411 words
A refrigeration system to selectively supply cooling to a space to be cooled and to heat a fluid including: a. refrigerant compressor means having an expanded refrigerant inlet and a compressed refrigerant outlet; b. reversing valve means including body means having an inlet communicating with said compressed refrigerant outlet and first, second and third outlet means and valve member means to selectively move from first position to permit communication between said first and second outlets where said valve inlet communicates with said third outlet to second position to permit communication between said second and third outlets where said inlet communicates with said first outlet; c. reversing valve control means to move said reversing valve member between said first and second positions; d. first heat exchange means having refrigerant inlet means communicating with said first outlet means of said reversing valve, first exchange fluid inlet means to introduce said fluid to be heated to said first heat exchange means to receive heat from said refrigerant in said first heat exchange means and first exchange fluid outlet means to emit fluid to be heated from said first heat exchanger and first heat exchanger refrigerant outlet means to emit refrigerant from said first heat exchanger; e. refrigerant heat exchange means having a first fluid flow aperture communicating with said third outlet of said reversing valve means and second fluid flow aperture means; f. bypass valve means inlcuding valve body means having first refrigerant inlet means communicating with said first heat exchange refrigerant outlet means and said refrigerant heat exchange means, second fluid flow aperture means and first outlet means communicating with said third reversing valve outlet and second outlet means connected to refrigerant evaporator means located in a space to be cooled and valve member means operable from a first position where said bypass valve inlet means communicates with said bypass conduit means to a second position wherein said bypass valve inlet means communicates with said second outlet means; g. conduit means communicating with the outlet of said evaporator means and said inlet to said compressor means; h. system control means including first temperature sensing means located in said first exchange fluid inlet means to activate said reversing valve means to said second position at preselected temperature and second temperature sensing means located in said space to be cooled and adpated to move said bypass valve member from said first position to said second position at preselected temperature in said space to be served
