Absorption Heat Pump for Heating Small Residential Buildings
The purpose of this project was the development of a Methanol/Lithium Bromide + Zinc Bromide absorption heat pump for heating one and two family residential buildings. For component design the relevant thermodynamic data of the ternary mixtures with a molar ratio LiBr/ZnBr sub 2 = 2:1 and 4:1 had to be completed. A prototype-unit (heating capacity: 10 kW) was built and tested under all conditions occuring in a real heating system. For application in indirectly fired absorption heat pumps (Generator temperature: <= 100 exp 0 C) a 4:1 mixture is favoured. Due to an excellent part load behaviour, the seasonal COP is as high as 1.56. The stability of stainless steel and copper in ternary solution mixtures was found to be sufficient.
