摘要：

The absorption cycle can be also of the open type. This concept has been utilized in developing solar cooling absorption systems. Another possibility not yet investigated is an open cycle absorption heat pump. The system rests upon the utilization of a packed tower operating with liquid desiccants. The tower dehumidifies both the exhausted air of heating plant and the exhaust of a natural gas boiler. A conventional heater heats up the regenerator of the sorbent and the inlet air. Simulations give a PER of the system (the open cycle heat pump) higher than 1.3 with respect to the Gross Calorific Value of natural gas. This value is difficult to obtain with the more complex closed cycle absorption or vapour compression cycle motor driven heat pump.
