Abstract
Abstract For solar heating (with cooperating cooling) both simplification and automatic control are needed. In the present invention solar heating and air conditioning apparatus is improved in various ways. For example, the furnace for auxiliary heat is eliminated. Operation of the solar heat collecting apparatus may be made automatic, or manual selective collection of solar heat may be obtained, for cold or cool weather conditions. A solar heat collector coating is provided that is changeable in absorption characteristics, so as to collect more heat when operating in winter and to reject heat when not operating during hot summer weather. An improved heat collector trough is provided for the solar heat collector.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
132 words
Combination heat storage (cold storage) and auxiliary heating apparatus comprising a container having liquid space adjacent to the bottom for heat storage and an air space adjacent to the top for auxiliary heat, means between said liquid space and said air space substantially separating said spaces, means for circulating liquid from said liquid space to a source of heat for warming and back to said liquid space for storage, means for supplying auxiliary heat to said air space to supplement stored heat from said liquid space, and means to channel air to be heated to an area adjacent to the bottom of said container and up around said container for preheating said air and adjacent to the top of said container for adding heat to said air by said auxiliary heat means.
Claim 2
Dependent Claim
132 words
Combination heat storage (cold storage) and auxiliary heating apparatus comprising a container having liquid space adjacent to the bottom for heat storage and an air space adjacent to the top for auxiliary heat, means between said liquid space and said air space substantially separating said spaces, means for circulating liquid from said liquid space to a source of heat for warming and back to said liquid space for storage, means for supplying auxiliary heat to said air space to supplement stored heat from said liquid space, and means to channel air to be heated to an area adjacent to the bottom of said container and up around said container for preheating said air and adjacent to the top of said container for adding heat to said air by said auxiliary heat means.
Claim 3
Dependent Claim
15 words
Apparatus as in claim 1 and additional heat storage-heat exchange material substantially surrounding said container.
Claim 4
Dependent Claim
27 words
Apparatus as in claim 2 wherein said additional heat storage material comprises non-flowable objects such as stones or containers of heat-of-fusion heat storage material or the like.
Claim 5
Dependent Claim
53 words
Apparatus as in claim 3 and a heat bin having wall, floor and top means surrounding said container and additional heat storage material in a substantially air-tight manner, and means to circulate air into said heat bin, through said material, and out to thereby heat (or cool) the air as it passes through.
Claim 6
Dependent Claim
35 words
Apparatus as in claim 1 and a solar heat collector, and means for circulation of liquid to be heated from the liquid space of said container to said collector and back to said liquid space.
