Heat pump for heating or refrigerating buildings and delivering in combination hot water for sanitary fixtures.

摘要

A reversible heat pump is disclosed in which there is provided a generator (10) of freezing fluid under the vapour state produced by a rectifying column (12) having perforated plates, with hydrostatic head on the plate assured by the surface tension of the liquid, a reboiler (14) of the vapour generator heated indirectly, a storage tank (34) of the condensate freezing fluid which contributes to control the cycle pressure for optimizing the efficiency under partial load conditions, lamination means (36) of the condensate freezing fluid which changes the flow section as a function of the pressure and controls the flow rate of the freezing fluid for draining any impurity, means (40) reducing the load loss of said lamination means during summer, a plate absorber (18) with swirl grid providing a microdrop flow between poor solution and freezing vapour fluid, and a multi-way valve (26) which allows said heat pump to be coupled with a split-exchanger (54) by deviating the flows of the operating fluids according to the requirements so as to cause said split-exchanger (54) to perform the function of cold source during winter and the function of hot drain during summer. <IMAGE>
