Solar-absorption hybrid modular cooling apparatus

摘要

The invention provides cooling apparatus comprising: a solar heat collection means (2); two or more absorption refrigeration modules (1), each module being arranged to receive heat from the heat collection means and to re-circulate refrigerant through an evaporator (16); and means for putting a fluid to be cooled into thermal contact with each of the evaporators.

1. Cooling apparatus comprising:
a solar heat collection means; two or more absorption refrigeration modules, each module being arranged to receive heat from the heat collection means and to re-circulate refrigerant through an evaporator; and means for putting a fluid to be cooled into thermal contact with each of the evaporators, each module has: a. a generator containing a solution of refrigerant in a liquid, the generator configured to receive heat from the heat collector and to cause evaporation of the refrigerant; b. only a single bubble pump configured to pump the liquid from the generator to an absorber; c. a condenser configured to receive gaseous refrigerant from the generator and to condense the same; d. an evaporator; e. means for passing liquid refrigerant from the condenser to the evaporator; f. said absorber is configured to receive gaseous refrigerant from the evaporator, absorbing the received gaseous refrigerant from the evaporator into the liquid from the bubble pump and returning the liquid to the generator; and g. a casing enclosing elements a-f and further including means for attaching said modules together.
