Effect of air speed and expansion valve openings on moisture content and dry air ratio in a modified air conditioning evaporator system

摘要

Air conditioning system has four main components of compressor, condenser, expansion valve, and evaporator. The effect of air speed and expansion valve openings on moisture content and dry air ratio in a modified air conditioning system has been investigated. The transerved air stream with the aid of a blower enters the evaporator through three baffles. Air flow capacity of the blower can be altered to get the variation of air speed entering the evaporator. The result of this research shows that the expansion valve openings have a significant change on the ratio of water vapor and dry air.
