Such changes are even more beneficial if they avoid using refrigerant chemicals such as freon .
如果避免使用像氟利昂这样的化学制冷剂,就会带来更有益的变化。
When the container holding this liquid is bathed in hot water , the refrigerant separates from the salty solution and is recovered to be used again .
装有这种液体的容器被放在热水中时,制冷剂就从盐溶液中分离出来,重新被利用。
Mr. mullings points out that 65 per cent of energy consumption is in refrigeration and air-conditioning , and the government is actively examining the use of the current hydro carbon refrigerant , which is highly inefficient .
Additionally , so much more aluminum would have to be used-to thicken the coils in order to improve efficiency and ensure that passageways in the unit were thick enough to withstand the high-pressure refrigerant moving through them-that units might not be that much lighter .
The warmer air surrounding the indoor coils heated the refrigerant , picked to boil at a low temperature , converting it from a liquid to a gas . The laws of physics dictate " phase changes " like this absorb heat , cooling the pipes .
室内螺旋管周围的热空气加热低沸点制冷剂,把制冷剂从液态变为气态,这一相变吸热而冷却螺旋管。
Resources for the future , an american think-tank , looked at regulations on things such as asbestos , power-station emissions and cfcs ( refrigerant gases ) and found that 12 of the 25 sets of rules it looked at were less expensive to implement than expected and only six were dearer .
A refrigerant vaporises , absorbing heat from the air to be cooled .
制冷剂变为蒸汽,吸收空气中的热量。
In conventional vapour-compression systems used by aircon units , the refrigerant is compressed and condensed and then expanded and evaporated to cool the room .
空调设备使用的传统的蒸发压缩循环系统中,冷却剂被压缩冷凝后膨胀气化来给房间制冷。
The compounds are in a class of gases related to a refrigerant that 's about to be banned in europe .
