Abstract

A solar heater/cooler assembly designed primarily for use with swimming pools with a pumping system and including heat exchanger coils and automatic temperature control to regulate the operation of the solar heater/cooler.

Claims

1. A swimming pool solar heater/cooler primarily designed for use with a swimming pool pump/filter system comprising heat exchanger means, inlet conduit means in fluid transmitting communication with said heat exchanger means, outlet conduit means in fluid transmitting communication with said heat exchanger means, first valve means in flow termination contact with said inlet conduit means, check valve means in said inlet conduit means, first T-connector means in fluid driving communication with the flow line of the pool pump/filter system and said inlet conduit means, second T-connector means in fluid dividing communication with the flow line of the pool pump/filter system and said outlet conduit means and located downstream from said first T-connector means, second valve means in flow terminating relation with the flow line from the pool pump/filter system and located substantially between said first T-connector and said second T-connector, said heat exchanger means further comprising substantially hollow linear tube means, substantially hollow, generally U-shaped tube means fluidly connecting said linear tube means to form coils of said heat exchanger means, said heat exchanger means further comprises substantially solar radiation resistant heat absorbing plastic tube means, temperature difference sensing means located in temperature sensing communication with said inlet and outlet conduit means, cross connect conduit means substantially in fluid communication between said inlet and outlet conduit means, automatic valve means located substantially in said cross connect conduit means and in responsive communication with said temperature difference sensing means.

2. A solar heater/cooler primarily designed for use with a swimming pool pump/filter system comprising heat exchanger means, inlet conduit means in fluid transmitting communication with said heat exchanger means, outlet conduit means in fluid transmitting communication with said heat exchanger means, first valve means in flow communicating contact with said inlet conduit means, check valve means in said inlet conduit means, first connector means in fluid dividing communication with a flow line of the pool pump/filter system and said inlet conduit means, second connector means in fluid dividing communication with the flow line of the pool pump/filter system and said outlet conduit means and located downstream from said first connector means, second valve means in flow terminating relation with the flow line from the pool pump/filter system and located between said first connector and said second connector, temperature difference sensing means located in temperature sensing communication with said inlet conduit means and said outlet conduit means, cross connect conduit means substantially in fluid communicating relation between said inlet and outlet conduit means, and automatic valve means located substantially in said cross connect means in electrical communication with said temperature difference sensing means, whereby the flow of water through said heat exchanger means may be regulated by said automatic valve means in response to said temperature difference sensing means.

3. A solar heater/cooler as in claim 2 wherein said heat exchanger means further comprises substantially hollow linear tube means, substantially hollow generally U-shaped tube means fluidly connecting said linear tube means.

4. A solar heater/cooler as in claim 2 wherein said heat exchanger means further comprises substantially solar radiation resistant, heat absorbing plastic tube means.
