- For a building located in Madrid, Spain with annual heating degree-days (dd) of 4654, a heating load (heat loss) of 30,000 kj/h, and a design temperature difference of 30° C (20° C indoor), estimate the annual energy consumption. If the building is heated with a furnace with an efficiency of 92%, how muchgas is burned to keep the home at 20° C? State your assumptions.A home is heated with propane with a 100,000 BTU furnace size and 95% efficiency. The monthly heating degree days is 5000. Using the energy estimation discussed in this chapter, estimate the monthly and annual gas consumption to heat the building if the home is to be kept 68°F.For a building located in London, England with annual heating degree-days (dd) of 5634, a heating load (heat loss) of 42,000 kj/h, and a design temperature difference of 35° C (20° C indoor), estimate the annual energy consumption. If the building is heated with a furnace with an efficiency of 98%, how much gas is burned to keep the home at 20° C? State yourassumptions.
- The Energy Efficiency Rating (EER) of an air-conditioning unit is defined asthe ratio of the heat removed in Btu/h divided by the energy used in watts.The EEI (Edison Electric Institute) names an air-conditioning unit as anEnergy Star unit if it has an EER of 13 or greater. A 21⁄2-ton air-conditioningunit uses 2.41 kilowatts (2,410 watts) of energy. One ton is equivalent to12,000 Btu/h. Can this unit be termed an Energy Star unit?2. A refrigerator has COP of 3.2. How much work must be supplied to the refrigerator in order to remove 320 J of heat from its interior?Consider a 400-MW, 32 percent efficient coal-fired power plant that uses cooling water withdrawn from a nearby river (with an upstream flow of 10-m3/s and temperature 20 °C) to take care of waste heat. The heat content of the coal is 8,000 Btu/lb, the carbon content is 60% by mass, and the sulfur content is 2% by mass. How much electricity (in kWh/yr) would the plant produce each year? How many pounds per hour of coal would need to be burned at the plant? Estimate the annual carbon emissions from the plant (in metric tons C/year). If the cooling water is only allowed to rise in temperature by 10 °C, what flow rate (in m3/s) from the stream would be required? What would be the river temperature if all the waste heat was transferred to the river water assuming no heat losses during transfer? Estimate the hourly SO2 emissions (in kg/h) from the plant assuming that all the sulfur is oxidized to SO2 during combustion.
- Replacing incandescent lights with energy-efficient fluorescent lights can reduce the lighting energy consumption to one-fourth of what it was before. The energy consumed by the lamps is eventually converted to heat, and thus switching to energy-efficient lighting also reduces the cooling load in summer but increases the heating load in winter. Consider a building that is heated by a natural gas furnace with an efficiency of 80 percent and cooled by an air conditioner with a COP of 3.5. If electricity costs $0.12/kWh and natural gas costs $1.40/therm (1 therm = 105,500 kJ), determine if efficient lighting will increase or decrease the total energy cost of the building (a) in summer and (b) in winter.Particle emissions in a house. The power goes out in your apartment (volume = 150 m3) at night, so you decide to light a few candles. These candles have a combined particle emission rate of E = 2.0 mg/h. Your apartment has a ventilation flow of 1.5 m3/min and the particles have a first order loss rate (due to deposition, which acts similar to a reaction) of 0.25 h−1, so: Write the differential equation and define the source and loss terms. Calculate the values for the source and loss terms and rewrite the differential equation with these values. What is the steady state particle concentration in your house (in μg/m3)? Write the time-varying solution to this problem and calculate the particle concentration after 1 hour of candle-burning (in μg/m3). If after 1 h of lighting the candles the power returns and the candles are all immediately put out, what will be the particle concentration 3 h after first lighting the candles?A typical ceiling of a house consists of items shown in the accompanying table. Assume an inside room temperature of 21° C and an attic air temperature of −10° C, with an exposed area of 100 m2 . Calculate the heatloss through the ceiling.
- A heat pump supplies heat energy to a house at the rate of 140,000 kJ/h when the house is maintained at 25°C. Over a period of one month, the heat pump operates for 100 hours to transfer energy from a heat source outside the house to inside the house. Consider a heat pump receiving heat from two different outside energy sources. In one application the heat pump receives heat from the outside air at 0°C. In a second application the heat pump receives heat from a lake having a water temperature of 10°C. If electricity costs $0.105/kWh, determine the maximum money saved by using the lake water rather than the outside air as the outside energy source.1) Heating the water in a 55-gallon water heater requires about 2.0 x 103 kJ of energy. a) Assume the energy came from natural gas with 80% efficiency; how many grams of natural gas are required? b) Assume the energy came from electricity with 80% efficiency and that the electricity was produced from the combustion of coal with 30% efficiency; how many grams of coal are required? For problem above, calculate how much CO2 in grams is emitted to the atmosphere. For a: Use the balanced equation for the combustion of methane (CH4) to determine how many grams of CO2are produced from the amount of natural gas required. For b: Assume that coal produces 5.25 kJ of energy per gram of CO2 produced. Calculate how much CO2 in grams is produced.Determine the energy consumption (BTU/min), If two 50-kg LPG tanks are needed per 24-hour operation, heating value for the LPG of 11,000 kcal/kg.
