Abstract
Abstract A solar energy heating or cooling system and method of performing the same is disclosed comprising a solar collector mechanism disposed generally on the roof of the structure for which it is to be used and supplied internally with a heat transfer medium of the halogenated hydrocarbon family having characteristics permitting expansion from a liquid to a gas, the collector mechanism being connected to an energy storage means having a plurality of conduit means disposed therewithin and connected to a reservoir for collection of a liquid, the liquid being pumped back to the solar collector mechanism by a pump for expansion into a gas, with control means being connected between the solar collector mechanism and the pump for controlling the level of the heat transfer medium.

Independent Claim
325 words
A solar energy collector system comprising: a. solar collector cell means having a substantially flat heat absorbing surface on at least one side thereof, said cell means including at least one fluid passage having input and output orifices; b. heat storage means having conduit means formed internally thereof, with one end of said conduit means communicating with said output orifice of said solar collector cell means, and having fluid conductors in said heat storage means independent of said conduit means constructed and arranged to be connected to a heat use device; c. liquid receiver tank means having its input port connected to the other end of said conduit means and having an output port; d. injection pump means having its input connected to said output port of said liquid receiver tank means and having its output connected to the input orifice of said solar collector cell means; e. a heat transfer medium having characteristics of a halogenated hydrocarbon fluid changing state between a gas and a liquid contained within each of said means; f. liquid level control means communicating with the input orifice of said solar collector cell means and the output orifice of said injection pump means, said liquid level control means controlling the level of said heat transfer medium in said solar collector cell means; g. check valve means fluidly disposed between said solar collector cell means output orifice and said one end of said first conduit means in said heat storage means preventing flow of said heat transfer medium towards said solar collector cell means; h. a liquid surge tank having its input and output connected between the output and input orifices respectively of said injection pump means and said solar collector cell means; i. and a pressure differential switch fluidly communicating with said input and output orifices of said solar collector cell means and controllably connected to said injection pump means for controlling the fluid level of said heat transfer medium.
