摘要

设计了一种基于多功能热管的高效吸附式制冰机组，采用氯化钙/活性炭复合吸附剂和氨作为吸附工质对。吸附床的加热解吸、冷却吸附及回热过程均由热管工作完成，对该新型吸附制冰机组进行了回质回热研究，结果表明，回质回热型循环可使机组的制冷性能系数COP提高25.5 %，加热量减小约13 %，同时冷却器负荷降低约21 %;采用先回质后回热方式，在回质过程中继续加热解吸床可进一步增加机组制冰量。与传统回质相比，系统COP和单位质量吸附剂制冷功率SCP提高幅度均在15 %以上，且机组SCP的提高幅度高于COP的幅度;吸附制冰机组性能随冷却水温度的升高而下降，但系统的SCP始终维持在较高的水平。当冷却水温度为27℃、蒸发温度为-18.9℃时，系统的SCP仍然高达356.5 W·kg-1。

Abstract

A multi-function heat pipe type adsorption ice maker

which uses activated carbon-CaCl2 as compound adsorbent and ammonia as refrigerant

was designed.For this test unit

the heating

cooling and heat recovery processes between two adsorbent beds were performed by multi-function heat pipes.The influence of recovery of mass and heat on the performance of adsorption ice maker was investigated.The experimental results showed improved recovery of mass and heat.The coefficient of performance (COP) was increased by 25.5 %

and the power consumption of boiler and the cooling capacity of cooler were reduced by about 13 % and 21 % respectively.When the mass recovery process was implemented before the heat recovery process

the mass recovery process with heating/cooling desorption/adsorption bed increased the rate of ice production obviously

which might help to increase COP and specific cooling power (SCP) by more than 15 % if compared with the conventional mass recovery process.The increase of SCP was higher than that of COP.Under the condition of different temperatures of cooling water

experiments showed that SCP was still high at a higher temperature of cooling water although the performance of adsorption ice maker dropped as temperature of cooling water became higher.At a cooling water temperature of 27℃ and an evaporating temperature of -18.9℃

SCP was still as high as 356.5 W·kg-1.
