摘要: Abstract A lab-scale adsorption heat pump with four adsorbers was tested. The core structure of the adsorber is aluminum alloy finned tubes. Water adsorbate (refrigerant) and a fine silica gel granule adsorbent. At regeneration temperature 77.5 °C, maximum SCP value 93 W/kg found. corresponding optimum cycle time 11 min and COP 0.31. considerably increases time. 35 min, reaches 0.54 73 W/kg gel. In process, evaporation rate liquid refrigerant in evaporator found to be much smaller than vapor adsorbent adsorber. This resulted slow process thus descent value.
