一、工作原理和理论分析热泵技术不仅早已用于采暖和空调领域,目前在石油、化工、冶金、轻纺和食品工业等方面也已得到广泛应用,并且均取得了良好的节能效果和显著的经济与社会效益。热泵与制冷机工作原理是相同的,唯一的区别是对热量的评价和使用目的不同,均属于按逆卡诺循环制成的机器。简言之,热泵蒸发装置就是以逆卡诺循环为理论基础,遵循热力学第二定律,借助输入一定量的高质能(电能、机械功),使工质在较低的温度下取得热量,并在较高的温度下排出热量的一种热能转化装 First, the working principle and theoretical analysis Heat pump technology has already been used not only in the field of heating and air conditioning, but has also been widely used in petroleum, chemical, metallurgy, textile and food industries, and has achieved good energy-saving effect and significant Economic and social benefits. The working principle of the heat pump and the refrigerator is the same, the only difference is that the evaluation of the heat and the purpose of use are different, and all belong to the machine made according to the reverse Carnot cycle. In short, the heat pump evaporation device is based on the inverse Carnot cycle theory and follows the second law of thermodynamics. By inputting a certain amount of high-quality energy (electrical energy, mechanical work), the working medium can obtain heat at a relatively low temperature. A thermal energy conversion device that emits heat at a higher temperature
