Author(s) : GEORGE J. M., MURTHY S. S.

Type of article: Article, IJR article

Summary

Tests were conducted on a 3 kilowatt 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 50-75 and 20-40 deg C, respectively. Heat delivery temperatures up to 85 deg C and temperature lifts up to 20 deg C were achieved. Actual COPs ranged from 0.2 to 0.35, whereas exergetic efficiencies of 0.3-0.4 could be obtained.
