The design of an air conditioning system allows for an inside design conditionof 22 °C and 60 % relative humidity. The outside air design condition was fixed as 32 °C drybulb and 22 °C wet bulb temperature. The air cycle operates as follows: After removal fromthe conditioned space the conditioned air is mixed with outside air in a mass flow ratio of onepart outside air to four parts inside air. This mixture is then cooled to a wet bulbtemperature of 7 °C, reheated to a dry bulb temperature of 18 °C and delivered to the airconditioned space. Determine (per kg dry air) the cooling capacity required, the reheatcapacity required and the ratio of sensible to total heat load inside the air conditioned space.
