1.a/ A house is heated at 22oC and has an average outdoor air infiltration rate of 0.15 ACH at standard operating conditions. If the average temperature outside over three months (91 days) is 2oC what would be the approximate energy consumption due to natural air infiltration? The house is 250 m2 in area and has 8 foot high ceilings throughout. b/If the house is being heated by a 100% efficient electric baseboard heater, what would be the savings due to...

The flow rate of warm air into the air conditioning is 5,000 cfm. An air conditioning system takes outdoor air at 95 degrees F dry-bulb and 70% relative humidity, and discharges it at 60 degrees F dry-bulb and 95% relative humidity. The air conditioning system operates on a vapor compression cycle using R134a between 20 and 200 psia. Refrigerant enters the compressor at 20 degrees F and leaves the compressor at 180 degrees F. Refrigerant enters the evaporator coil at...

Air at 40 degrees C is humidified by flowing over a 1-m-long container filled with water. The surface area of container is 0.5m^2.The interfacial temperature is 20 degrees C. If the initial humidity of the air is 0% and its velocity is 0.5 m/s, calculate the mass flow rate of vapor evaporated.

Air at 480Kpa is expanded adiabatically to a pressure of 94Kpa. It is then heated at constant volume until it again attains its temperature, when the pressure is found to be 150KPa. it then undergoes an isothermal compression to return the air to its original state. Using this information sketch the p-v diagram and calculate the value of γ. If the initial temperature of air is 190oC determine the work done per kg during the adiabatic expansion and teh isotherman...

An air conditioning system is to take outdoor air at 30 oC and 70% relative humidity at a steady rate of 10 m3/s and to condition it to 25 oC and 50% relative humidity. The outdoor air is first cooled down to 13.9 oC using cooling coil and then heated to the desired condition in the heating section. Assuming the air is at 1 atm pressure, Draw the air conditioning process on the attached psychometric chart. Determine the mass flow...
