- What is passive cooling of buildings? explain various passive cooling technologies with the help diagrams. Which technologies are suitable for UAE climate? Hint: UAE climate is very hot sometimes 45 degrees and 30% humidity.Which of the following does not affect the demand for cooling in a given space? Select one: a. Number of occupants in the given space b. Positioning of the room in the house c. Direction where the building is facing d. Cooling capacity of the cooling systemBuilding requires to maintain different temperature settings. What are most common cooling system used here in Singapore.?
- Discuss three ways to remove water from the air in an air distribution system.Explain the HVAC system with the most suitable energy medium for usage in Architectural constraints of Commercial buildings. Illustrate with your own mathematical example of Temperature scale.In a high rise building complex, identify and describe the functions of different components of air conditioning systems
- A forced convection heating system is installed in a house. The lengths of6-inch circular duct that are needed are: kitchen, 6 feet; dining room, 12 feet;living room, 3 feet; master bedroom, 5 feet; second bedroom, 7 feet; thirdbedroom, 13 feet. How many feet of 6-inch round duct are needed?Explain the similarity and difference of Air Pressure System and Downfeed/Overheadfeed System types of Cold Water Distribution System.A classroom that normally contains 40 people is to be air-conditioned with window air-conditioning units of 5-kW cooling capacity. A person at rest may be assumed to dissipate heat at a rate of about 360 kJ/h. There are 10 lightbulbs in the room, each1 with a rating of 100 W. The rate of heat transfer to the classroom through the walls and the windows is estimated to be 15,000 kJ/h. If the room air is to be maintained at a constant temperature of 21°C, determine the number of window air-conditioning units required.
- A heat load calculation is being done to determine how much heat is beinglost through a wall. The area of the wall (not including the window) must becalculated in square feet. Find the area of the wall shown.List at least three variables (structures) that affect the loss of heating and cooling in the building (house).A house is being built. The contractor states that the cost to install electricbaseboard heat will be $2,480. The contractor also states that a forced air,heat pump system will be 21⁄4 times as much. How much will the heat pumpsystem cost?
