A single-effect ammonia absorption-ejection heat pump system is set up. Combined with T-S diagram, performance analysis is presented on the heat pump system with ejector or without ejector. The results show that, with the ejector coefficient equal to 0.5, and the cooling coefficient of performance of the single-effect ammonia absorption heat pump equal to 0.3, 0.45 and 1.45 can at least be gained for the heating coefficient of performance and the cooling coefficient of performance respectively. In this paper, relation curve diagram is also presented for the heating coefficient of performance of absorption-ejection heat pump system, the cooling coefficient of performance of single-effect absorption heat pump system and the ejector coefficient.

Exhaust Heat Recovery

For large-scale public shower facilities which open up at a specified time, (such as those in schools, barracks, and natatoriums), a great deal of heat is wasted. If this exhaust heat can be recovered and recycled, it will have significant impact in saving energy and environmental protection, with significant economic benefits. In this paper, two different kinds of heat pumps, an electric and an absorption heat pump, used in heat recovery systems are proposed. Specifically, the used shower water is drained through a pipe and first collected in a gray water pool. After a period of time, as the wastewater accumulates volume, the heat pump system can begin heat recovery and recycling. The wastewater is filtered through a filter and piped to a heat exchanger to heat the tap water. Therefore, the tap water temperature can be heated from 12°C to 25°C, and the wastewater temperature will drop from 30°C to 17 °C. Afterwards, the wastewater is piped to the heat pump evaporator and the tap water piped to the condenser for additional heating. At the same time, according to the different characteristics of the electric heat pump and absorption heat pump, different heat recovery system processes and control are detailed. On this basis, the paper analyses the economic and environmental benefit of three schemes for retrofitting based on a practical example: “exhaust heat recovery using electric heat pump”, “exhaust heat recovery using electric heat pump + gas boiler” and “exhaust heat recovery using direct-fired heat pump”, then finds that direct-fired absorption heat pump heat recovery have lower energy consumption, less pollution, lower operating costs, payback period is shorter and has a promising practical application.

Abstract Absorption system have been investigated for many years. However, coefficient of performance COP or heat gain factor HGF for absorption systems are significantly lower than those for conventional compression systems. This has restricted their wide application. This paper discusses the behavior of mixture NH3-H2O through of an ejector, operating in an absorption heat pump system. This combination improves the performance of conventional absorption system and with the phasing out of ozone-damaging refrigerants, absorption refrigerators, heat pumps and air-conditioning now provide a potential alternative. For the detailed calculation of the proposed system a method has been developed, which employs analytical functions describing the thermodynamic properties of die mixture. The influence of three major parameters: generator, condenser and evaporator temperature, on ejector efficiency and heat gain factor of the system is discussed. Also the maximum value of HGF was estimated by correlation of above three temperatures.
