Title: Yearly simulation of a solar-aided R22-DEGDME absorption heat pump system

Abstract

The performance of a solar-aided R22-DEGDME absorption heat pump system designed for 100 kW cooling capacity is investigated by a computer simulation using hourly data for Ankara. In summer the generator, and in winter the evaporator, receives solar energy while the remaining demands are met by auxiliary heaters. When needed, these boost the temperature of the water from the storage tank to the minimum allowable levels which are determined as 20{degree}C in winter and over 80{degree}C in summer. The system performance, judged by the fraction of the load supplied from solar energy, is affected mostly from the climate, source temperature limit, collector type and area but little from storage tank size, for the sizes and configuration under investigation. With 400 m{sup 2} of high efficiency collectors, the solar energy supplied 38% of the demand in winter and 91% of the demand in summer. 22 refs., 2 figs., 6 tabs.
