摘　　要：介绍了太阳能冷管结构原理,并对它的制冷和供热特性做了实验研究.结果表明:在太阳辐射为23.5 MJ/m2情况下,太阳能冷管在白天加热脱附阶段能够将4 kg的水从25℃加热到约50℃;晚间吸附制冷阶段,能够将4 kg的水从26℃加热到39℃,并且可以产生276 kJ的冷量,制冷系数COP可达0.22.This paper presened the structure and experimental study of a solar cooling tube. The solar cooling tube consists of four major components： solar collector, adsorbent bed, condenser and evaporator all in one glass tube. It chooses the zeolitel3X water as working pair and is environmental friendly. To evaluate its heating and refrigeration performance, an experiment was conducted on a typical day： total solar energy to the solar adsorption cooling tube is about 23.5 MJ/me , a solar cooling tube is capable of heating 4 kg of water to about 50 ℃ in daytime and 4 kg of water to about 39 ℃ at night, as well as producing a refrigeration capacity of about 276 kJ. Its coefficient of performance can reach 0.22.
