Description
技术领域technical field
本发明属于供暖、通风及空气调节技术领域，特别是涉及机械蒸汽再压缩(MVR)高效浓缩技术再生溶液结合除湿的空调系统装置。The invention belongs to the technical field of heating, ventilation and air conditioning, and in particular relates to an air conditioning system device combining mechanical vapor recompression (MVR) high-efficiency concentration technology regeneration solution combined with dehumidification.
背景技术Background technique
目前具有环保节能特点的除湿空调系统已经成为国内外学者研究的热点课题。溶液除湿不需要消耗冷冻除湿后再次升温到送风状态点的能量。研究表明，除湿的空调系统可比传统空调系统节约运行能耗30％以上。At present, the dehumidification and air-conditioning system with the characteristics of environmental protection and energy saving has become a hot topic of research by scholars at home and abroad. Solution dehumidification does not need to consume the energy of heating up to the air supply state point after freezing and dehumidification. Studies have shown that the dehumidified air-conditioning system can save more than 30% of the energy consumption in operation compared with the traditional air-conditioning system.
目前市场上用的除湿溶液绝大多数为溴化锂溶液(LiBr)溶液等盐溶液，是由于浓溶液具有强烈的吸水性。可以解决空气湿度过高容易滋生细菌、发霉变质等空气品质问题。把吸收空气水分后的稀溶液浓缩成浓溶液循环使用调节空气湿度具有很大的经济价值和运用价值。Most of the dehumidification solutions currently on the market are salt solutions such as lithium bromide solution (LiBr) solution, because the concentrated solution has strong water absorption. It can solve air quality problems such as high air humidity, easy to breed bacteria, mildew and deterioration. Concentrating the dilute solution after absorbing air moisture into a concentrated solution for recycling and regulating air humidity has great economic value and application value.
目前可运用的溶液再生方式，从再生原理角度，主要有加热再生，膜法再生和超声波再生等，其中加热再生方式的研究居多，技术也较为成熟。从热源角度，加热再生又可分为太阳能集热再生、余热能量回收再生、电加热再生等。不过这些方法在一些特殊的环境下除湿效果和运行稳定性不佳，例如在阴雨天除湿量较大、而太阳能不足造成的太阳能集热再生器再生效率不高或是余热再生方式在冬夏两季热量不平衡导致的运行不稳定除湿效果不佳等问题。Currently available solution regeneration methods, from the perspective of regeneration principles, mainly include heating regeneration, membrane regeneration and ultrasonic regeneration, among which heating regeneration methods are mostly studied and the technology is relatively mature. From the perspective of heat sources, heating regeneration can be divided into solar heat collection regeneration, waste heat energy recovery regeneration, electric heating regeneration, etc. However, these methods have poor dehumidification effect and operational stability in some special environments. For example, the dehumidification capacity is large in rainy days, and the regeneration efficiency of the solar collector regenerator is not high due to insufficient solar energy, or the waste heat regeneration method is ineffective in winter and summer. Unstable operation caused by heat imbalance, poor dehumidification effect and other problems.
另外，目前的液体除湿技术的发展还面临许多急需解决的问题。溶液再生器性能系数不高，除湿溶液的物性限制了系统COP的进一步提高等等。针对出现的各种问题，国内外的学者作了大量的研究工作：首当其冲是进行湿度处理装置、再生器新型式的开发与研究。由于除湿溶液的再生方式是液体除湿空调系统的重要环节，影响整个系统的除湿效果和运行稳定性，所以，溶液再生方式也是国内外学者研究的热点之一。In addition, the development of the current liquid dehumidification technology still faces many problems that need to be solved urgently. The coefficient of performance of the solution regenerator is not high, and the physical properties of the dehumidification solution limit the further improvement of the system COP and so on. In response to various problems, domestic and foreign scholars have done a lot of research work: the first is to carry out the development and research of new types of humidity treatment devices and regenerators. Since the regeneration method of the dehumidification solution is an important part of the liquid dehumidification air-conditioning system, which affects the dehumidification effect and operation stability of the whole system, the solution regeneration method is also one of the hot spots of domestic and foreign scholars.
不同再生方式的研究其本质是为了提高再生效率，降低能量消耗。而机械蒸汽再压缩(MVR)技术基于热泵的工作原理，经过少量电能的输入，将二次蒸汽的低位热能转换为加热蒸汽的高位热能，具有无需冷凝器、料液要求低、操作、简单、能耗低、无需冷凝水、成本低等优点。同时在真空环境下，将降低除湿溶液溶液沸点，提高蒸发效率。理论上使用机械蒸汽再压缩技术比传统的蒸发设备可节省80％以上的能源，其运行成本也显著降低。该技术已在工业、食品、海水淡化、废液处理等蒸发领域应用广泛。The essence of research on different regeneration methods is to improve regeneration efficiency and reduce energy consumption. The mechanical vapor recompression (MVR) technology is based on the working principle of the heat pump. After a small amount of electric energy input, the low-level heat energy of the secondary steam is converted into the high-level heat energy of the heating steam. Low energy consumption, no condensation water, low cost and other advantages. At the same time, in a vacuum environment, the boiling point of the dehumidification solution will be reduced and the evaporation efficiency will be improved. Theoretically, the use of mechanical vapor recompression technology can save more than 80% of energy compared with traditional evaporation equipment, and its operating cost is also significantly reduced. This technology has been widely used in evaporation fields such as industry, food, seawater desalination, and waste liquid treatment.
鉴于MVR蒸发技术具有良好的节能性和经济性，可以较好的适应环境变化带来的运行不稳定性和浓缩再生效果不佳等问题。因此其在液体除湿领域也应具有广阔的应用和推广前景。同时也是对液体除湿空调系统的一种创新、丰富和发展。In view of the fact that MVR evaporation technology has good energy saving and economical efficiency, it can better adapt to the problems of unstable operation and poor concentration regeneration effect caused by environmental changes. Therefore, it should also have broad application and promotion prospects in the field of liquid dehumidification. At the same time, it is also an innovation, enrichment and development of the liquid dehumidification air conditioning system.
