Abstract: In some special places, some small style desalinating
units are needed for living, and heat pump may be considered to carry
out it because of its efficiency and saving energy. For designing the
small desalinating heat pumps system, it is a basic aim that the units
can provide 3.6 kg pure water in an hour. According to different working
conditions (condensation temperature and evaporation temperature being
changed), heat transfer coefficient in heat exchangers and heat transfer
area of heat exchangers are computed, besides of those, length of
capillary tube is calculated too, and some relationships among
condensation temperature, evaporation temperatures and those parameters
are analyzed and presented. Those results are helpful to machining and
assemble of the small desalinating heat pumps.
Key words: Desalination Heat pump Working conditions’ choice
