Optimum design of solar solid-absorption ice machine

The optimum design of a solar solid-absorption ice machine was put forth with CaCl₂/NH₃ as working medium. The solid absorbent can be used for depressing dissolving effect, while CaCl₂/NH₃ has good affinity. The basic idea of this design is that the working temperature should be kept as low as possible in order to increase efficiency with constant total ammonia output. The results of simulation test showed that the efficiency is higher with the temperature decrease of heat collecting plate, so that the ice production is increased.
