If you have to design a venue for an exhibition show. or a concert which has The shape is square, the dimensions are width x length x height equal to 200x500x10 meters and can hold people equal to 5,000 people determine that the combustion in the human body to release energy per person equal to 95 W. outdoor temperature according to the weather conditions of Thailand But the temperature inside the building must can be controlled at 20°C If there is an event with full capacity of the venue and have students determine the heat loss or getting heat from the outside of the place itself (in watts) 1. If it is in winter when the outside air temperature is 15°C and the place is installed The fan blows the outside air in. and ventilate the inside out at the flow rate Air is equal to 0.5 cubic meters per second. Find out if it is possible at the temperature inside the premises. that full capacity equals 20°C 2. In the summer when the outside air temperature is 40°C, calculate that air conditioning must be installed. how many total Find information of the air conditioner itself. Hint provides if the amount of energy per time. 1 air conditioner can support) to keep the internal temperature equal to 20°c (no use fans to extract and ventilate) 3. From item 2, when the temperature inside the premises is 20°C and then a power failure occurs, when After 2 hours, what is the temperature inside the place? 4. Your assistant has suggested an idea to reduce the temperature inside the premises by 1) spraying water. Control the whole place 2) Use insulation to cover the outside of the whole place. Analyze which method works. better, by using the computational method Thermodynamics A​
