Making the units more energy-efficient could double that.Air-conditioning is one of the world's greatoverlooked industries. Automobiles and air-conditioners were invented at roughly the same time, and both have had a huge impact on where people live and work. Unlike cars, though, air-...
1. Air Conditioning & Heating AC and heating systems are the primary sources of comfort inside the home, insulating it from the extreme cold or hot temperatures outdoors. When looking at energy consumption, an HVAC system uses the most energy of all, coming in at about 52% of the energy ...
1.C.细节理解题.根据第一段On one calculation, replacing refrigerants (制冷剂)damaging the atmosphere would reduce total greenhouse gases equaling 90bn tonnes of CO2 by 2050. Making the units more energy-efficient could double that. 有一项计算表明,到2050年,更换有害大气的制冷剂将减少相当于900亿吨...
aThe most important and cost effective element of an efficient heating, ventilating, and air conditioning (HVAC) system is a well insulated building. A more efficient building requires less heat generating or dissipating power, but may require more ventilation capacity to expel polluted indoor air. ...
Filling your freezer to capacity makes it more energy-efficient by minimizing the amount of warm air that can enter it when you open the door. Also, the mass of the contents helps to recool the air. You can use non-food items like newspapers, bags of shipping peanuts and containers filled...
Look for the Energy Star logo to denote efficient appliances. The Energy Star rating was created by the EPA in 1992 to label appliances with high energy efficiency. These ratings are now widespread and can help you find the most efficient air conditioner for your particular space. ...
The answer is: make air-conditioners (空调)much better. On onecalculation, replacing refrigerants(制冷剂)that damage the atmosphere would reduce total greenhouse gases by90bn tonnes(公吨)of CO: by 2050. Making the units more energy-efficient could double that. By contrast,if halfthe world's ...
