Description
技术领域technical field
本发明涉及深度溶液除湿技术领域，特别是涉及一种空气型太阳能与热泵相结合的双热源驱动的溶液除湿机组的技术领域。The invention relates to the technical field of deep solution dehumidification, in particular to the technical field of a solution dehumidification unit driven by dual heat sources combined with air-type solar energy and a heat pump.
背景技术Background technique
随着世界经济的不断发展，人们对能源的需求量也越来越大，能源问题成为目前人类发展中面临的一个重大难题，如何提高不可再生能源利用率，以及如何合理利用可再生能源，将成为解决这一难题的关键点。With the continuous development of the world economy, people's demand for energy is also increasing. Energy issues have become a major problem in human development. How to improve the utilization rate of non-renewable energy and how to rationally use renewable energy will be become the key point to solve this problem.
溶液除湿就是利用有除湿能力的盐溶液对空气进行除湿。溶液的表面水蒸气分压力和空气的水蒸气分压力差是二者进行质量传递的驱动力。为了增加热质传递的驱动力，需要对溶液进行降温(除湿过程)或者升温(再生过程)。从而使热泵技术得以与溶液除湿技术结合使用。Solution dehumidification is to use a salt solution with dehumidification ability to dehumidify the air. The difference between the surface water vapor partial pressure of the solution and the water vapor partial pressure of the air is the driving force for the mass transfer between the two. In order to increase the driving force of heat and mass transfer, the solution needs to be cooled (dehumidification process) or heated (regeneration process). This enables heat pump technology to be used in conjunction with solution dehumidification technology.
溶液除湿空调系统，相比于传统中央空调系统，有多方面的优势。目前在民用建筑中，常用的除湿方式是冷凝除湿。冷凝除湿过程中，凝结水落在室内机水盘内，形成湿表面，容易滋生霉菌等细菌。除湿后的空气往往温度较低，还需要再热，满足送风要求，造成了能源浪费。而溶液除湿就不会这样的问题，除湿后的空气送入房间，房间内没有湿表面，避免了霉菌滋生的危险，可以满足各种热湿比状态的送风，无需再热，高效且节能环保。Compared with the traditional central air-conditioning system, the solution dehumidification air-conditioning system has many advantages. At present, in civil buildings, the commonly used dehumidification method is condensation dehumidification. During the condensation dehumidification process, the condensed water falls into the water pan of the indoor unit, forming a wet surface, which is easy to breed mold and other bacteria. The air after dehumidification is often at a lower temperature and needs to be reheated to meet the air supply requirements, resulting in a waste of energy. The solution dehumidification will not have such a problem, the air after dehumidification is sent into the room, there is no wet surface in the room, avoiding the risk of mold growth, and can meet the air supply of various heat-humidity ratio states, no need to reheat, high efficiency and energy saving Environmental friendly.
热泵驱动的溶液除湿空调系统，目前在公共建筑中作为舒适性空调已有应用，在一些工业场合(如物料干燥过程)，作为工艺性空调有所应用。但是该系统中，除湿后的溶液需要被送至再生侧再生，提高其浓度，以实现循环利用。为了实现再生，通常再生侧溶液的温度要达到60℃以上。同时除湿侧需要对溶液降温，尤其对于深度除湿系统，除湿侧溶液需要的温度更低，即需要热泵的蒸发温度更低。蒸发温度和冷凝温度的大温差使得热泵效率很低，能耗较高。这是目前热泵驱动的溶液除湿空调系统最大的缺点之一。The heat pump-driven solution dehumidification air-conditioning system has been used as a comfort air conditioner in public buildings, and has been used as a technological air conditioner in some industrial occasions (such as material drying process). However, in this system, the dehumidified solution needs to be sent to the regeneration side for regeneration to increase its concentration to achieve recycling. In order to achieve regeneration, the temperature of the solution on the regeneration side is usually above 60°C. At the same time, the solution needs to be cooled on the dehumidification side, especially for the deep dehumidification system, the temperature of the solution on the dehumidification side is lower, that is, the evaporation temperature of the heat pump is lower. The large temperature difference between the evaporating temperature and the condensing temperature makes the efficiency of the heat pump very low and the energy consumption is high. This is one of the biggest drawbacks of current heat pump driven solution dehumidification air conditioning systems.
以太阳能为热源对再生供热是很好的解决办法。太阳能热水系统制出的热水温度在70℃以上，完全可以满足再生需求。且除湿侧配备一台制冷机，为除湿溶液降温。制冷机的冷凝温度不需要达到60℃以上，只需要比环境温度略高，这使得制冷机效率提高，实现了节能的目的。尤其在深度除湿场合应用，太阳能驱动的溶液除湿空调系统更具优势。除湿侧只需要将溶液温度降低至需求温度，而不必有过高的冷凝温度，制冷机能效比提高。再生侧利用太阳能作为热源，减少了一次能源的利用。实现了节能减排的目的。Using solar energy as a heat source is a good solution to regenerative heating. The temperature of hot water produced by the solar water heating system is above 70°C, which can fully meet the regeneration needs. And the dehumidification side is equipped with a refrigerator to cool down the dehumidification solution. The condensing temperature of the refrigerator does not need to be above 60°C, but only needs to be slightly higher than the ambient temperature, which improves the efficiency of the refrigerator and realizes the purpose of energy saving. Especially in the application of deep dehumidification occasions, the solar-driven solution dehumidification air-conditioning system has more advantages. The dehumidification side only needs to reduce the solution temperature to the required temperature without having to have an excessively high condensation temperature, and the energy efficiency ratio of the refrigerator is improved. The regeneration side uses solar energy as a heat source, which reduces the utilization of primary energy. Achieved the purpose of energy saving and emission reduction.
