Summary
Ammonia has been used as the refrigerant in large systems continuously since the beginning of the era of refrigeration. In small systems, it has hardly been used at all since the introduction of the halogenated hydrocarbons around 1930. Lately, with the search for alternatives with less influence on global warming, the use of ammonia in small systems has come into focus again. In the paper, the author describes the work done at the Royal Institute of Technology with the aim of developing a prototype of a domestic water-to-water heat pump with a heating capacity of around 6 kW. It has been shown that such a system can be designed to operate with less than 100 g of ammonia. The main obstacle for introducing this technology commercially is the lack of components. Particularly, there seems to be no hermetic or semi-hermetic compressor available in this size range.
