The ALH series product is the "heat exchanger air processor". The venting of air conditioner and the new air coming into the room should first enter into this equipment. The venting air and new air do the heat exchanger. Use the energy of venting to pretreat the new air. In summer and winter, the new air can get the cooling and drying or warming and wetting processing so as to do the energy cycling to ensure the circulation of fresh air in the room and effectively recycle the energy. The core part of ALH heat exchanger air processor uses the wing board structure. It can make the cross convection. The special treated film separates the air coming in and the air venting out, making sure the efficient exchanging of the heat and the fresh air coming into the room. Its specialites are: 1) The film of the filter is very small, you almost cannot see the fiber constitution of the air hole that reduces the circulating ratio of water-solubility gas, such as ammonia and hydrogen. 2) The crossing airflow board is made of a kind of environment protection board. With the high hydrosphere particularity, it helps the exchange of the vapor that improves the exchanging efficiency of the heat and reaches the conversion of low efficient gas and high efficient heat. The ALH1 series product adds functions of ozone sterilization, ultraviolet radiation antisepsis, adding oxygen by negative hydronium and the automatic shut off when there is no person. During the usage, open the machine for N minutes, the machine will automatically do the processing to purity the indoor air thoroughly, making the air quality like the air in the forest. The product has won the national patent.
