Abstract

The effectiveness of heat pump system of low-temperature water heating, using pre-heated air from burning a small amount of fuel, has been analyzed. Using this system improves the operating conditions of heat pump and increases its transformation ratio respectively, compared to the system with no furnace extension. It will allow, firstly, increasing the temperature range of air-water heat pumps, and, secondly, abandoning the reserve heat source, that in turn will decrease capital spending. Graphical dependencies of key parameters, characterizing the system performance, on environmental temperature are given in the paper. It has been found that the size of furnace extension was small compared to the heat removed from the air for meeting the heating purposes.
