Heating system deriving solar energy from panels - feeds storage vessel and controls circulation of liquid medium by output temp. of heat source

摘要

The central heating system has a closed space containing a medium such as water, which is heated. The heating energy is derived from solar panels and given off to an exchanger which transfer it to an enclosed space. The circulation of the water is controlled as a function of the temp. of the water at the output of the heat source and as a function of the temp. at the input of the enclosed space and as a function of the temp. at the output of the enclosed space. The temp. at the output of the heat source is equal to the temp. of the water at the input of the enclosed space (10). The flow of the water will be stopped if the temp. at the output of the heat source is smaller or equal to the temp. of the water at the output of the enclosed space even is the temp. at the output of the source is greater than the other two temps.
