An experimental study of a newly designed freezing desalination unit equipped with reversed vapor compression cycle

A newly designed freezing desalination system was constructed. The system operates on the principle of reversed vapor compression. It is equipped with two identical heat exchangers, one of them works as an evaporator and the other as a condenser. A three-way valve was used to reverse the operation o...
