背景技术Background technique
随着人们生活水平的提高，人们对房间空气的品质要求越来越高，对新风的要求也越来越多。目前，空调行业也相应的推出了多种与房间新风相关的空气处理机组，主要有包括三大类，但各种类型产品都有一定的缺陷。其一是大型的新风处理机组，工作原理与冷暖空调一样，最主要用于集中办公或大型商业场所，不能回收排除污浊空气的冷量或热量，不适用于家庭安装，局限性很大。其二是全热回收机组，使用范围很广，能够回收排除污浊空气的冷量或热量，但不能单独对空气进行制冷或制热和加湿处理，需要单独增加空调对空气进行处理，同时需要单独增加空气加湿器对空气加湿，对用户来说功能过于单一，整体成本高。其三是空调器和新风送风机的结合，新风需要借助空调来进行加热或降温，一般风量较小，不能对空气进行加湿处理，不能回收排除污浊空气的冷量或热量，很难满足新风量的要求。With the improvement of people's living standards, people have higher and higher requirements for the quality of room air, and more and more requirements for fresh air. At present, the air conditioning industry has also launched a variety of air handling units related to room fresh air, mainly including three categories, but each type of product has certain defects. One is a large-scale fresh air treatment unit, which works the same as a heating and cooling air conditioner. It is mainly used in centralized offices or large commercial places. It cannot recover and remove the cold or heat of dirty air. It is not suitable for home installation and has great limitations. The second is the total heat recovery unit, which has a wide range of applications and can recover and remove the cooling or heat of dirty air, but it cannot separately cool or heat and humidify the air. It needs to add an air conditioner to process the air separately. Adding an air humidifier to humidify the air is too single-function for the user, and the overall cost is high. The third is the combination of the air conditioner and the fresh air blower. The fresh air needs to be heated or cooled by the air conditioner. Generally, the air volume is small, and the air cannot be humidified, and the cooling or heat of the dirty air cannot be recycled. It is difficult to meet the fresh air volume Require.
