Thermodynamicclass contains 32 undergrad students. The plan is to air-conditionthe classroomwith air-conditioning units of 8-kW cooling capacity. It is assumed that on average each studentdissipate heat at a rate of about 300 kJ/h. There are 12lightbulbs in the room, each with a rating of 100 W. The rate of heat transfer to the classroom through the walls and the windows is estimated to be 14,000 kJ/h. If the room air is to be maintained at a constant temperature of 23oC,i.e. ∆?????≈0, determine the number of air-conditioning units required.

A particular frost-free refrigerator uses about 745 kWh of electrical energy per year. Express this amount of energy in unit cal.
energy can be conserved when your home heating/cooling system works less during the heating and cooling seasons. in fact/ a one degree celsius difference in your thermostat setting can reduce energy consumption by up to 5%
3. 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 light bulbs in the room, each 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 210C, determine the number of window air-conditioning units required. draw a figure also, and explain each step by step solution.

You are replacing an HVAC system in your building. The system is a steam system that consists of a boiler that feeds several air-handling units. The total heating load for the building is 3613 thousand Btuh. The building has 15 floors in total. What is the required total flow rate (in lb/hr) of the steam to satisfy the heating load?
SANAE IV, a research station of The South African National Antarctic Programme (SANAP), is located on Vesleskarvet, Queen Maud Land. It uses an underground lake as the cold reservoir of a Carnot heat pump that maintains the temperature of a science lab at 307.8 K. To deposit 17360 J of heat in the lab, the heat pump requires 1086 J of work. Determine the temperature of water in the underground lake, in Kelvin.
Based on the mechanisms of thermal energy exchange what would happen if you exercised in a colder place where it's 5⁰C.
1. .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.
A 3,500-seat auditorium is to be air-conditioned using window units 10 kW nominal value. Assume that a person at rest will dissipate heat at a rate of approximately 360 kJ/h. There are 200 lamps in the auditorium, each rated at 250 W. The rate of heat transfer to the auditorium through the walls and windows is estimated to be equal to 150,000 kJ/h. If the auditorium air goes to maintain at a constant temperature of 200°C, determine the number of air conditioning units of required window. Answer: 45 units.
