.Mexico's metro requires the implementation of an air conditioning system for each of its cars. On the hottest days the air inside the car can reach 45°C. A temperature of 25°C is expected to be achieved to keep passengers satisfied. A car measures 17 m x 2.5 x 2. In order to make the decision on the air conditioning system to install, the engineering director has asked to calculate: A. Amount of energy to be removed from the car when the air is at 45°C and the car is empty. B. Amount of energy to withdraw when the car is full (approx. 130 people with a volume of 0.06 m3/person). Each person releases 30 kJ while in the car. C. Power of a system that removes the estimated energy A and B in less than 1 minute
Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
