Abstract
Abstract A combination heat pump and low temperature solar heat collector includes a compressor and lines having a restrictor for forming vapor and condensate sections. The collector comprises containers for liquid, which may be water, mixed with substances for lowering the freezing point and for darkening the liquid or for influencing the heat conductivity. The heat pump has a reversing valve to convert the evaporator tubes, winter setting, to condenser tubes, summer setting. Solar radiation or ambient air restores heat to the cooled water.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
165 words
A heat transfer means including a heat pump comprising a compressor having high and low pressure lines containing a refrigerant, a heat exchange device, said heat exchange device having means forming separate compartments therein, a distinct mass of material in each of said compartments, heat transfer ducts disposed in heat exchange relation with said mass of material in each of said compartments, said heat transfer means including circulation means to conduct said refrigerant from said compressor through said lines and into said heat transfer ducts in heat exchange relation with said distinct masses in said heat exchange device, said circulation means including a second means to sequentially direct the refrigerant into only one of the heat transfer ducts while the other ducts are disconnected from said circulation means, and means to expose said compartments to the open sky including the portion of the sky encompassing the apparent path of the sun, thereby tending to restore the original level of heat energy to said disconnected portions.
Claim 2
Dependent Claim
165 words
A heat transfer means including a heat pump comprising a compressor having high and low pressure lines containing a refrigerant, a heat exchange device, said heat exchange device having means forming separate compartments therein, a distinct mass of material in each of said compartments, heat transfer ducts disposed in heat exchange relation with said mass of material in each of said compartments, said heat transfer means including circulation means to conduct said refrigerant from said compressor through said lines and into said heat transfer ducts in heat exchange relation with said distinct masses in said heat exchange device, said circulation means including a second means to sequentially direct the refrigerant into only one of the heat transfer ducts while the other ducts are disconnected from said circulation means, and means to expose said compartments to the open sky including the portion of the sky encompassing the apparent path of the sun, thereby tending to restore the original level of heat energy to said disconnected portions.
Claim 3
Dependent Claim
14 words
The heat pump of claim 1 wherein the mass of material is a liquid.
Claim 4
Dependent Claim
13 words
The heat pump of claim 2 wherein the mass of material is water.
Claim 5
Dependent Claim
16 words
The heat pump of claim 3 wherein the water contains material for lowering the freezing point.
Claim 6
Dependent Claim
20 words
The heat pump of claim 4 wherein each said portion of water is divided into components having different freezing points.
Claim 7
Dependent Claim
34 words
The heat pump of claim 1 including a reversing valve means to reverse the connections of the high pressure and low pressure lines to the said mass and to the said heat exchange device.
Claim 8
Dependent Claim
15 words
The heat pump of claim 6 having a transparent cover for the mass of material.
Claim 9
Dependent Claim
19 words
The heat pump of claim 7 having a means to move air into heat exchange with said distinct masses.
Claim 10
Dependent Claim
15 words
The heat pump of claim 8 having reflective shutters for directing sunlight onto the mass.
