申論 5請將下列英文譯成中文。(20 分)The expansion valve is the regular through which the refrigerant passes fromthe high pressure side of the system to the low pressure side. The pressure dropcauses the evaporating temperature of the refrigerant to fall below that of theevaporator. Thus, for example, the refrigerant can be boiled off by anevaporator temperature of -18 ℃because the pressure drop brings theevaporating temperature of the refrigerant down to say -24℃.
