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.
