摘要
A novel cycle in which adsorbent heat transfer is enhanced by forced convection is described. The cycle is modelled for the carbon-ammonia pair, but could be used for any high pressure refrigerant. Mean heat output when used as a heat pump is of the order of kilowatts per kg of adsorbent. Heat pumping COPs of about 1.3 are predicted for the situation modelled, but the regenerative nature of the cycle gives rise to the belief that COPs up to a maximum of 1.9 may be possible with optimised energy management within the system.
