摘要: A centrifugal compressor having an improved efficiency is constructed by providing a diffusion channel and vanes downstream of a diffuser, the diffusion channel being coupled to the diffuser through a U-turn channel, the outlet side passage of the U-turn channel being made larger than the inlet side passage and the kinetic energy being recovered at the diffusion channel. Further improvement is achieved by providing guide vanes in the U-turn channel.

摘要: A desiccant assisted air conditioning system, incorporating desiccant members in each of separate passages for process air and regeneration air, is presented to significantly improve the cooling efficiency to utilize the low and high temperature heat sources of a heat pump device. While one desiccant is dehumidifying so that moisture in the process air is being adsorbed in the one passage while the regeneration air is removing moisture from the desiccant in the other passage. The combined effect of this arrangement enables to produce cooling effect in excess of the cooling capacity of the heat pump device, and to achieve a significantly higher energy efficiency for operating the air conditioning system.
