Candidate Chemical Systems for Air Cooled Solar Powered,Absorption Air Conditioner Design. Part I. Organic Absorbent Systems.

摘要

All the available experimental evidence suggests that the optimum ''organic''absorbent/refrigerant combination would be a methane derivative with a single hydrogen atom with chlorine and fluorine atoms in the other sites,as refrigerant. This would be hydrogen bonded to an absorbent molecule containing the group =NC exp - O,with the substituent groups being such that no steric hindrance took place. Cycle analyses showed that the ratio of internal heat transfer to cooling would be large,probably impractically so in view of the high coefficient of performance needed for solar driven cooling and the additional handicap of heat rejection to the atmosphere. A more promising approach would be to reduce the internal heat transfer per unit of space cooling by selecting a refrigerant with a high latent heat of vaporization and selecting an absorbent with suitable properties.
