An individual independent pressure circuit for a diffusion absorption heat pump has multiple insulated boiler tubes heated by a single gas heater with a common flue outlet

摘要

The boiler has separate hermetically sealed parallel tubes (3) in which the ammonia refrigerant is heated by a common gas flame (7) and common flue (9) and each leading to a condenser (4), evaporator (5), absorber (6) and reservoir (8). The boiler tubes are arranged in close proximity and thermally insulated (10).
