Abstract
Tests were conducted on a 3 kW heating capacity R21-DMF vapour absorption heat transformer to study the influence of operating temperature on its performance. Heat source temperature and condensing temperature were varied in the ranges 50-70°C and 20-40°C, respectively. Heat delivery temperatures up to 85°C and temperature lifts up to 20°C were achieved. Actual COPs range from 0.2 to 0.35, whereas exergetic efficiencies of 0.3-0.4 could be obtained. © 1993.
