通常,热泵和致冷器使用共沸混合物作热载体。但在大多数情况下,特别是在工业生产中,热量由蒸发器预先提高,并在10—20℃和非恒温状况下传输给致冷器,由此产生的热量不可逆性会降低热泵的性能系数。为克服此缺点,法国石油学院提出利用在温度范围内蒸发和冷凝的非共沸液作热载体来改进热泵的热力学性能,并发明了Frinip卤化液混合物。当外面液体的温度变化大时和交换器的热偏差小时,热泵应用效果更好些。此外,使用逆流交换
In general, heat pumps and chillers use azeotropic mixtures as heat carriers. However, in most cases, especially in industrial production, heat is pre-increased by the evaporator and transmitted to the refrigerator at 10-20 ° C and non-constant temperature conditions. The resulting irreversibility of heat reduces the performance of the heat pump coefficient. To overcome this shortcoming, the French Petroleum Institute proposes to improve the thermodynamic performance of heat pumps by using a non-azeotropic liquid which evaporates and condenses in the temperature range as a heat carrier and invent a Frinip halogenated liquid mixture. The heat pump works better when the temperature of the outside liquid varies greatly and when the heat deflection of the exchanger is small. In addition, the use of countercurrent exchange
