Total load of a building is 60 kW with sensible- and latent-heat gains in a space served by a single-zone air conditioner are 50 and 10 kW, respectively. The space is to be maintained at 24°C and 50 percent relative humidity. The design conditions of outdoor air are 40°C dry-bulb -and 30°C wet-bulb temperatures. For ventilation purposes outdoor air is mixed with recirculated air in a 1:4 proportion. When mixed air at the resulting conditions enters the cooling coil, the outlet air conditions are a function of the temperature of the chilled water supplied to the coil, as indicated in Table below. Determine (a) the air conditions entering the coil, (b) the air conditions leaving the coil and the required temperature of the supply chilled water, and (c) the cooling capacity of the coil.

An inventor claims to have developed a reversed heat engine (ie. a heat pump) which is able to deliver 10 kj heat into the room at 20°c from outside ambient temperature of -10°c by consuming only 2 kj electricity in winter. this claim is a)-impossible b)-possible only if the heat pump is ideal c)-practically possible d)-unable to be assessed as it depends on the working fluid used in the heat pump.
