<p>A heat-driven adsorption cooling unit, comprising:
- a condenser having an input end and an output end;
- an evaporator having an input end and an output end, the input end being connected to the output end of the condenser via an operable valve; and
- a series of sorption-desorption generators, each of which has input and an output ends for connection to the condenser and evaporator to create a refrigerant flow circuit, and a heat supply for operating each generator at high and low temperatures, the generators being operable to flow refrigerant through the condenser and evaporator to provide a cooling effect at the evaporator;
wherein
the series of generators comprises two pairs of generators, each pair comprising:
- a first generator having an output end connected to the input end of the condenser via a first non-return valve arranged to prevent flow from the condenser to the first generator; and
- a second generator having an input end connected to the output end of the evaporator via a second non-return valve arranged to prevent flow from the second generator to the evaporator, and an output end connected to the input end of the first generator via a third non-return valve arranged to prevent flow from the input end of the first generator to the output end of the second generator;
each pair of generators being separately operable to drive fluid through the condenser and evaporator to provide a cooling effect.</p> |
