Abstract
A solar heating system including a chemical heat pump for storing thermal energy by converting same into energy in the form of a difference in the concentration of an aqueous multiple-component chemical solution which actuates the chemical heat pump, and a solar collector of a low temperature solar collection type operative to collect excess thermal energy of the sun not used for heating and cooling purposes during the time intermediate the solar irradiance abundant season and the solar irradiance scarce season, or spring and autumn, and store same in the chemical heat pump as energy in the form of a difference in the concentration of an aqueous multiple-component chemical solution. Warm water obtained by heating water by the solar heat collector is supplied in the wintertime to the chemical heat pump as a low temperature heat source and control of flow of a working medium is effected depending on the amount of the solar energy collected in the wintertime, so as to thereby increase the efficiency with which the solar energy is utilized during the intermediate season and winter.
