Design and Construction of Solar Absorption Refrigerator Using Organic Compound (R134a and Tetraethelene Glycol Dimethyl Ether)

Abstract:

Absorption refrigerator is not a new concept. It provides advantages of being silent, of having no compressor, which also makes it lasting a long life cycle. Particularly, it can utilize low level waste energy. In this contribution, a 2-fluid aqua-ammonia prototype is analysed and an overall design and construction procedure of a mini-type, 3-fluid absorption refrigerator is given, with working fluids of organic compounds (R134a as refrigerant and Tetraethelene Glycol Dimethyl Ether as absorbent) and a pressure balancing gas. The aim of this project is to develop a potential mini-type cooling system for rural areas, where electricity is scarce or non-existed. The experiments showed the combination of R134a and TEG.DEM for mini-type solar absorption refrigeration is theoretically realisable; To have an ideal performance, except of interfusion of non-condensable gas and impermeability of the system, the filling methods, vacuum drawing state as well as the stability of input power are all crucial influence factors.
