Hybrid absorption heat pump with ammonia/ water mixture e Some design guidelines and district heating application.

Author(s) : MINEA V., CHIRIAC F.

Type of article: Article, IJR article

Summary

An ammonia/water mixture can be used as an efficient working fluid in industrial-type heat recovery heat pumps and heat transformers. Several configurations of such systems are possible depending on the availability of the waste (thermal) and primary (thermal or electrical) energy sources. This article presents the configurations, the main thermodynamic and hydraulic parameters, and some design guidelines and operating experiences of a medium-temperature, ammonia/water-based compression/re-sorption heat recovery system for district domestic hot water production. In-field experiments have proven the advantages of the concept and its applicability limits in a particular economical environment, while hot water was produced at 55°C with industrial cooling water at 36°C as a waste heat source.
