Description
技术领域technical field
本实用新型涉及空调领域的除湿设备，尤其是涉及一种溶液式全热回收机组。The utility model relates to dehumidification equipment in the field of air conditioning, in particular to a solution type total heat recovery unit.
背景技术Background technique
在空气调节领域，夏季通常需要对室外进来的空气进行降温除湿处理，冬节通常需要对室外进来的空气进行加热加湿处理。传统的空调系统中大多采用冷凝除湿处理方式，即采用制冷机制备出低温的冷却水，通过冷却水在表冷器的盘管中循环并与空气进行热量交换，将空气温度降低到露点以下，使空气凝结出水分从而实现对于空气的除湿处理。这种除湿方式一方面，使制冷机工作在低蒸发温度情况下，导致制冷机的性能系数较低，另一方面，冷凝除湿后的空气湿度虽满足要求但温度过低，一般还需要再热才能达到送风温度要求，造成了能源的二次浪费。另外，由于凝结水的存在使表冷器盘管等处很容易滋生细菌、霉变，降低了送风品质，严重影响室内空气的质量。In the field of air conditioning, it is usually necessary to cool and dehumidify the incoming air in summer, and to heat and humidify the incoming air in winter. Most of the traditional air-conditioning systems adopt the condensation dehumidification treatment method, that is, the low-temperature cooling water is prepared by the refrigerator, and the cooling water circulates in the coil of the surface cooler and exchanges heat with the air to reduce the air temperature below the dew point. Condenses moisture from the air to dehumidify the air. On the one hand, this dehumidification method makes the refrigerator work at a low evaporation temperature, resulting in a lower coefficient of performance of the refrigerator. On the other hand, although the air humidity after condensation dehumidification meets the requirements, the temperature is too low, and generally needs to be reheated. In order to meet the air supply temperature requirements, resulting in a secondary waste of energy. In addition, due to the existence of condensed water, it is easy to breed bacteria and mildew in the coils of the surface cooler, which reduces the quality of the air supply and seriously affects the quality of the indoor air.
为克服传统空调系统冷凝除湿方式存在的缺陷，本领域的技术人员研究开发了溶液调湿方式，即采用具有调湿性质的盐溶液作为工作介质，与新风直接接触并进行热质交换，当空气的水蒸汽分压力高于盐溶液的表面蒸汽压时，盐溶液就会吸收空气中的水分；而当空气的水蒸汽分压力低于盐溶液的表面蒸汽压时，盐溶液中的部分液态水就会变为气态进入空气中，从而实现对空气湿度的调节目的。目前市场上溶液除湿空调系统往往包括一整套设备，较适合季节变换比较分明的地区，对于春夏交接和秋冬交接时期或四季不分明的地区，往往不需要对空气进行深度除湿(加湿)和降温(加温)处理，只需对空气稍加进行深度除湿(加湿)和降温(加温)处理即能满足送风要求，在这种情况下，如果成套使用溶液除湿空调系统或负荷运行系统，一方面投入成本较高，另一方面能耗也会相对较高，造成资源浪费。In order to overcome the shortcomings of the traditional air-conditioning system condensation dehumidification method, technicians in the field have researched and developed the solution humidity control method, that is, the salt solution with humidity control properties is used as the working medium, and it is in direct contact with the fresh air for heat and mass exchange. When the air When the water vapor partial pressure of the salt solution is higher than the surface vapor pressure of the salt solution, the salt solution will absorb the moisture in the air; and when the water vapor partial pressure of the air is lower than the surface vapor pressure of the salt solution, part of the liquid water in the salt solution It will change into a gaseous state and enter the air, so as to achieve the purpose of regulating the air humidity. At present, the solution dehumidification air-conditioning system on the market often includes a complete set of equipment, which is more suitable for areas with clear seasonal changes. For areas where the transition between spring and summer and autumn and winter or the four seasons are not clear, it is often not necessary to deeply dehumidify (humidify) and cool the air. (heating) treatment, only a little deep dehumidification (humidification) and cooling (heating) treatment of the air can meet the air supply requirements. In this case, if the solution dehumidification air conditioning system or load operation system is used in a complete set, On the one hand, the input cost is high, and on the other hand, the energy consumption will be relatively high, resulting in waste of resources.

新风和回风处理过程：Fresh air and return air treatment process:
夏季工况下，室外新风从新风——送风通道左端进入，首先经新风过滤器进行过滤和静电除尘处理，再通过下部热回收器并与其中的盐溶液进行热湿交换，使其中的盐溶液吸收新风的热量和水分以冷却新风和除湿，经以上步骤处理后的新风最后经送风风机输送到室内。室内回风从右端进入回风——排风通道，首先经回风过滤器进行过滤除尘处理，过滤除尘后的回风经排风风机输送到上部热回收器，与其中的盐溶液进行热湿交换，使回风带走盐溶液的热量和部分液态水，最后回风排出室外。本实用新型送风风机和排风风机均采用变频风机，可根据室内外参数进行变频调节，以节药能源和增强机组的运行稳定性。排风量以不小于送风量的70％为宜，理想状态下，排风量等于送风量的80％效果最好。Under summer working conditions, the outdoor fresh air enters from the fresh air——the left end of the air supply channel, and first passes through the fresh air filter for filtration and electrostatic dust removal treatment, and then passes through the lower heat recovery device and performs heat and moisture exchange with the salt solution in it to make the salt in it The solution absorbs the heat and moisture of the fresh air to cool the fresh air and dehumidify, and the fresh air processed through the above steps is finally delivered to the room through the air supply fan.

夏季工况下，盐溶液通过下部热回收器的第三喷淋装置进行喷淋并与新风直接接触进行热湿交换，盐溶液吸收新风的热量和水分温度升高，然后由溶液循环泵将温度升高的盐溶液从下部热回收器的第三溶液箱输送到上部热回收器的第三喷淋装置，并在喷淋过程中与回风直接接触进行热湿交换，回风带走盐溶液中的热量和部分液态水，盐溶液温度降低，再从上部热回收器的第三溶液箱中流到下部热回收器的第三喷淋装置，如此反复循环运行。In summer working conditions, the salt solution is sprayed through the third spray device of the lower heat recovery device and directly contacts with the fresh air for heat and moisture exchange. The elevated salt solution is transported from the third solution tank of the lower heat recovery unit to the third spray device of the upper heat recovery unit, and is in direct contact with the return air for heat and moisture exchange during the spraying process, and the return air takes away the salt solution The heat and part of the liquid water in the salt solution will reduce the temperature, and then flow from the third solution tank of the upper heat recovery device to the third spray device of the lower heat recovery device, so that the cycle runs repeatedly.
