ADSORPTION HEAT PUMP REFRIGERATION/POWER COGENERATION METHOD

WIPO Patent Application WO/2015/196882

A1

An adsorption heat pump refrigeration/power cogeneration method, per which a scheme of direct expansion is utilized, work medium vapor produced via desorption by a first absorption bed (1) is allowed to expand, work, and depressurize directly in a first expander (3), exhaust steam discharged by the first expander (3) is absorbed of heat by an evaporator (4) and evaporated, a refrigerant liquid is thus allowed to evaporate into low-pressure vapor, and the low-pressure vapor is introduced into a second adsorption bed (6) to be adsorbed of released heat. The exhaust temperature of the first expander (3) can be less than the ambient temperature. With the exhaust temperature reduced, the efficiency of a steam-powered apparatus is increased. System efficiency is higher compared with a hybrid power system consisting of organic Rankine steam cycles. Adsorbed heat can also be utilized to produce steam as a driving heat source; hence, a self-driven system is implemented, the need for a high-temperature driving heat source is obviated, only a single low-grade heat source is required, and, refrigeration, heating, and power supply can be implemented simultaneously. This is a low-carbon environmentally friendly heat, refrigeration, and power cogeneration apparatus.
