Hello Sir,Good Morning.I have a question in my homework related thermodynamics lesson. The following below is my question. Please advice. Thank you. Regards,Irfan An air conditioning system is used to keep the house at 65°F when the outside temperature is 85°F. The house gets heat through the walls and windows at a rate of 810 Btu/min, and the rate of heat generation inside the house from occupants, lights, and equipment is 120 Btu/min. Determine the minimum power input required for this air conditioning system.
Which of the three air-conditioning possible systems listed below should be used to maintain the indoor temperature of a house at 20°C while resulting in a daily lower operating cost when the outdoor temperature is -2°C. Based on the construction of the house you estimate that under the given indoor and outdoor temperatures the rate of heat loss to the surroundings is 17 kJ/s. Which system would you recommend as a feasible alternative? Support your answer for each one of the cases below with convincing computations that show which one of the systems is requires the minimum electrical power while being in compliance with the first and second law of thermodynamics. a. Electrical heating b. A heat pump with COPHP = 3.0 c. A heat pump with COP = 14.0
An air-cooled window DX unit is used for space cooling. The unit has a capacity of 4.5 tons and has a SEER of 15. If the unit operates for 2204 hours during the summer, how many kWh of electricity will be used? Hint: In the U.S., the SEER is the ratio of cooling in British thermal units (BTUs) to the electrical energy consumed in watt-hours. You may need to convert the unit in this process.
Heat is produced by computers while they run. Do you have any questions concerning computer cooling systems?
Estimate how much collector area and storage capacity would be required for an active solar hot-water system designed to supply the total needs for two four-person families, one living in Manchester, New Hampshire, where the latitude is 44+°N, and the other in Albuquerque, New Mexico, at 35+°N. The heat capacity of water is about 4,200 J/kg°C, and the hot-water supply temperature in both houses is 75°C (140°F). State and justify all additional assumptions made.
A heat pump uses 100 J of energy as it operates for a given time. Isit possible for the heat pump to deliver more than 100 J of heat tothe inside of the house in this same time? Explain
