I am trying to cool and dehumidify air using a vapor-compression refrigeration cycle. Due to the wanted exit state Temp and relative humidity of desired air, I am having to cool below the exit state temp to get the same specific humidity as the exit state specific humidity. Then I am going to use an air to air heat exchanger to heat up my air to the desired exit state temp. What is the best way to calculate Qlmin? I have found my Ql using the psychrometric charts although is it going to change due to the air to air heat exchanger?
