An improved ice producing system of assisting liquid desiccant evaporative supercooled water
چکیده انگلیسی


• An improved ice producing system of evaporative supercooled water is proposed.
• The new system realizes cascade utilization of the low humidity ratio air.
• The ice producing rate of system can increase by 33.8% under certain conditions.
• The evaporative supercooled characteristics of water droplets were analyzed.

Supercooled water method is a high efficiency dynamic ice producing mode. However, there are some disadvantages such as ice blocking problem and high electric energy consumption. In order to solve these problems, an improved ice producing system with assisting liquid desiccant evaporative supercooled water is proposed. The improved system adds an evaporative precooling subsystem of water. The dehumidified air entering ice producing chamber is cooled by the cooling water of system itself rather than mechanical regeneration cycle compared to the original system. The new system could realize cascade utilization of the low humidity ratio air. The amelioration can not only improve the ice producing efficiency, but also further reduce the dependence of the system on electric energy. The evaporative cooling characteristics of water droplets were analyzed by theoretical model and the experiment. The temperature variation of droplets predicted by theoretical calculation was basically consistent with the experiment. Finally the performance analysis of system has been made. Compared with the traditional supercooled water method, the ice producing rate of the improved system can increase by 33.8% under certain working conditions.
