Abstract
An air conditioning system making use of waste heat comprising a compound absorption refrigeration machine and absorption type heat pump for both cooling and heating. The refrigeration machine and the heat pump are connected in parallel to the load to obtain hot water for utility of air heating, and the refrigeration machine operates utilizing hot water produced by the heat pump to produce cold water for air cooling.
Claims5
An air conditioning system making use of waste heat comprising, in combination, an absorption refrigeration machine switchable between operation modes for cooling and heating, said refrigeration machine using a high-temperature fluid such as hot water or steam as a first driving heat source, and an absorption type heat pump making use of warm waste water as a second driving heat source and as an absorption heat source to thereby obtain hot water hotter than said second driving heat source, whereby, in the operation mode for heating, said absorption refrigeration machine and said absorption type heat pump are connected in parallel to a load so that hot water obtained by the heating mode of said absorption refrigeration machine and hot water obtained from said absorption type heat pump are directly fed to said load, whereas, in the operation mode for cooling, said absorption refrigeration machine is operated utilizing the hot water produced by said absorption type heat pump as a heat source to produce cold water or ice for cooling purpose, the hot water produced by said absorption type heat pump replacing said first driving heat source in the operation mode for cooling.
