In order to achieve solar adsorption refrigeration, this paper studies the
surface water source solar absorption refrigeration system combined with
surface water source cooling and solar absorbent refrigeration techniques: the
solar radiation intensity is adjusted by changing the distance between iodine
tungsten lamps and solar cold tubes. The results show that the entire cycle
has a range of solar radiation intensity of 400 to 1000 W/m2, and the indoor
ambient temperature ranges from 19 to 25◦C, and the humidity is maintained
around 40%. The highest temperature in the solar cold tube adsorption bed is
12◦C; during the adsorption process, the temperature drops to about 20◦C; the
solar cold tube is 160 kJ in one cycle of the solar cold tube, and the cooling
coefficient is about 0.15. Conclusion: solar cold tubes can effectively utilize
solar refrigeration, it is a refrigeration method for environmentally friendly,
no greenhouse effects and ozone destruction, which has potential application
value and has energy saving and environmental protection.
