Compound adsorbent for adsorption ice maker on fishing boats
Abstract Adsorption performances of three types of adsorbents, CaCl 2 with different expansion space, simple compound adsorbent and solidified compound adsorbent made by CaCl 2 and activated carbon, are tested, in which ammonia is used as refrigerant. The solidified compound adsorbent shows the best performance for adsorption ice makers on fishing boats for the larger filling quantity of adsorbent in adsorber. The mass transfer performance is improved by the additive of activated carbon in solidified compound adsorbent at the condition of low evaporating temperature. The volume cooling density of solidified compound adsorbent is about 35% improved at least in comparison with the optimal results of CaCl 2 at the evaporating temperature of −15 °C.
