Japanese Patent JPH0473061
Kind Code:
B2
Abstract:
A multi-effect heat pump comprises at least three pairs of exchange units A, B; C, D; E, F, i.e. units which operate as generator, condenser, evaporator or absorber in at least two interconnected heat-pump circuits. Each pair operates in a different pressure range and the exchange units of each pressure range operate in different temperature ranges. An exchange unit (B) operating as condenser in an upper pressure range is adapted to deliver heat of condensation to a first exchange unit (C) operating as a second generator in a medium pressure range, and a second exchange unit (E) operating as absorber in a lower pressure range is adapted to deliver heat of absorption to a second exchange unit (D) operating in said medium pressure range. Means (84, 160, 166) are provided for selectively enabling and disabling alternatively the transfer of heat to said first exchange unit (C) or to said second exchange unit (D) to adapt the operation of the heat pump to varying conditions and demands.
