A residential air-conditioner with COP of 4.0 re-circulates 0.4 kg-DA/s of indoor air that is cooled and dehumidified as it flows over the cooling coil. THe warm indoor enters the unit at 30 C with a dew point of 20 C. THe chilled air exits the unit at 10 C at 100% relative humidity. Liquid condensation drains out at 10 C. Changes in kinetic and potential every are negligible. Atmospheric pressure is 101 kPa.
Use the "Psych Chart" to obtain all property data. Tabulate values in a STATE TABLE.
a) Find the required cooling capacity and the condensate flow rate.
b) Find the required air-conditioner power input.
