Summary
Waste water with a temperature below 60°C is generally discharged because its temperature is too low for use as an energy source. The authors are therefore developing a hybrid air-conditioning system driven by low-temperature waste heat at about 60°C. Specifically, they have established the following technology: low-temperature waste heat driven absorption system. In detail, a two-stage absorption cycle was selected which satisfied the target of a refrigeration cycle COP of 0.4 with minimum heat transfer area requirements. To demonstrate the two-stage absorption cycle driven by 60°C waste heat, the heat transfer area required by the heat exchangers were calculated using a cycle simulation software program. A proof-of-concept machine was designed and constructed based upon the results of the calculations. Operation of the proof-of-concept machine verified that the target cooling capacity and COP can be achieved utilizing the two-stage absorption cycle under 60°C waste heat conditions.
