The most popular refrigerant used in the past for residential air-conditioning is R- ________.
In single duct air conditioning system; 1 kg/s of outlet air at - 6°C db, 75 % RH mixes with 3 kg/s of the return air at 24°C db, 50% RH. The mixture air sensibly heated to 38°C db, then humidified (Twb =const.) to 24°C db. Draw the processes on the psychrometric 1. Heating coil capacity. 2. Quantity of the moisture
In air handling unit, the 0.8 kg/s of the outlet air at 40C db, 28C wb mix with 2.4 kg/s of the return air at 24C db, 50% RH. The mixture passes through the water cooling coil have surface temperature ADP = 8C. Assume the contact factor of the cooling coil is 80%. Draw the processes on the psychrometric chart, then find: 1. Cooling coil capacity. 2. Quantity of the removed moisture.
A combination air cooler and dehumidification unit recover outside ambient air at 35 oC, 100 kPa, 90% relative humidity. This air-water vapor mixture is first cooled to a low temperature to condense the proper amount of water, after which the air-vapor mixture is heated, leaving the unit at 20 oC, 30% relative humidity. The volume flow rate of the air-vapor mixture at the exit conditions is 0.01 m3/s. Find the temperature to which the mixture is initially cooled, and the mass of water condensed per kilogram of dry air. Assuming that all the liquid water condensed leaves the unit at the minimum temperature, calculate the overall heat transfer rate.
