Description
技术领域technical field
本发明涉及的是一种除湿空调装置。特别是一种超声波强化再生除湿的除湿空调装置，属于超声波及空调工程应用技术领域。The invention relates to a dehumidification air conditioner. In particular, the invention relates to a dehumidification and air-conditioning device for ultrasonic-strengthened regenerative dehumidification, which belongs to the technical field of ultrasonic and air-conditioning engineering applications.
背景技术Background technique
在潮湿地区的夏季，除湿空调与普通空调相比，具有较好的节能效果。除湿空调的基本原理是：首先利用干燥剂吸附被处理空气中的水分，然后利用冷盘管对空气降温。除湿空调运行当中，关键一步是干燥剂的再生。目前，通常是利用高温热源对干燥剂进行再生，已有技术中，申请号为200410018292，名称为混合式除湿空调的发明专利，直接利用加热器对干燥剂进行再生；申请号为03273614，名称为新型的太阳能吸附除湿空调及热水装置的发明专利，则利用太阳能热水器的高温热水对干燥剂进行再生。上述两种方法均利用外界的高品位热能对干燥剂进行再生，使再生后的干燥剂温度很高，不但影响干燥剂吸附水分的能力，而且导致被处理空气的温度上升，进而增加冷盘管的显冷负荷。这样，当被处理的空气湿度较小，潜冷负荷不大时，这种除湿空调的节能效果并不明显，有时可能还会比普通空调的能耗大。因此，降低干燥剂的再生温度，是发挥除湿空调节能优势的关键。但再生温度直接影响干燥剂的再生效率，再生温度越低，再生效率也将越低。In summer in humid areas, dehumidifying air conditioners have better energy-saving effects than ordinary air conditioners. The basic principle of dehumidification air conditioner is: first use desiccant to absorb the moisture in the air to be treated, and then use cold coil to cool down the air. In the operation of desiccant air conditioners, the key step is the regeneration of desiccant. At present, the desiccant is usually regenerated by using a high-temperature heat source. In the existing technology, the application number is 200410018292, and the name is an invention patent of a hybrid dehumidification air conditioner, which directly uses a heater to regenerate the desiccant; the application number is 03273614, and the name is The invention patent of the new solar adsorption dehumidification air conditioner and hot water device uses the high temperature hot water of the solar water heater to regenerate the desiccant. The above two methods both use external high-grade heat energy to regenerate the desiccant, so that the temperature of the regenerated desiccant is very high, which not only affects the ability of the desiccant to absorb moisture, but also causes the temperature of the treated air to rise, thereby increasing the cooling capacity of the cooling coil. sensible cooling load. In this way, when the humidity of the air being processed is low and the latent cooling load is not large, the energy-saving effect of this dehumidification air conditioner is not obvious, and sometimes it may consume more energy than ordinary air conditioners. Therefore, reducing the regeneration temperature of the desiccant is the key to give full play to the energy-saving advantages of dehumidification air conditioners. But the regeneration temperature directly affects the regeneration efficiency of the desiccant, the lower the regeneration temperature, the lower the regeneration efficiency will be.
