An air conditioning system making use of waste heat is described comprising a compound absorption refrigeration machine and absorption type heat pump for both cooling and heating. The refrigeration machine and the heat pump are ...

In this investigation, an absorption water chiller and absorption heat pump were extensively tested under steady-state and cyclic operating condtions. Since the tests were performed on two different units, one for a cooling only and one for a heating only...

The air conditioning apparatus according to the invention comprises an absorption type heat pump comprising a system including an absorber, a regenerator, a condenser and an evaporator. A mixture of lithium bromide and zinc chloride is used as an absorbent which is dissolved to form an absorbent solution into a ...

In this investigation, an absorption water chiller and absorption heat pump were extensively tested under steady-state and cyclic operating condtions. Since the tests were performed on two different units, one for a cooling only and one for a heating only application, the report is set up in two parts discussing the results of the ...

An absorption water chiller and an absorption heat pump were extensively tested under steady state and cyclic operating conditions. Since the tests were performed on two different units, one for a cooling only and one for a heating only application, the results of the testing of each unit are reported separately. In addition to the ...

A solar assisted heat pump is described and illustrated. The operation of the heat pump is explained. (WDM)

In a recent survey of 108 industries in the U.S., it was found that large amounts of thermal energy at relatively low temperatures was discharged to the atmosphere through industrial effluents. For the purpose of thermally upgrading such low temperature thermal energy, mechanical and absorption type heat pumps have ...

Gas heat pumps are coming, but by a different name. The manufacturers have elected not to call these products {open_quote}heat pumps{close_quotes} because advertising by gas distributors has been so effective at associating the term {open_quote}air-source heat ...

Chemical heat pumps are mechanically driven heat pumps with working fluids that undergo chemical changes or are heat-driven heat pumps in which either the driver (heat engine) or heat pump ...

A heat pump is a device which elevates the temperature of a heat flow by a means of an energy input.

GRI has selected three gas heat pump (GHP) concepts as the most promising for early commercialization and growth potential: dual-cycle absorption, reciprocating engine-driven, and rotary engine-driven. The near-term objective is to achieve market entry of an absorption GHP, an adsorption GHP, or an internal combustion (IC) engine-driven GHP in the early ...
