How does the fresh air exchanger achieve energy saving in public buildings?
Requirements of housing urban and rural development to strengthen the government office and large public building energy efficiency management and establish accountability system, the public building energy efficiency work included in the "11th five-year plan" of the department work for energy conservation and emissions reduction targets and central fresh air system environment full heat exchange of air to pass and indoor ventilated take a breath of fresh air person for our heat recovery of air at the same time, Make it less energy efficient to cool or heat our homes.

Heat exchange (heat recovery) system is a kind of air supply and exhaust system with heat recovery function added on the basis of bidirectional flow. Its system principle and two-way flow is the same, the difference is that the air supply and exhaust is only completed by a host, and the host internal added a heat exchange core with energy exchange function, can quickly absorb heat and heat, to ensure sufficient energy exchange between cold and hot air. The exhaust of outdoor dirty air and fresh air sent into the room in this total heat exchange device for heat exchange, so as to achieve the purpose of recycling cold quantity, heat, saving air conditioning energy.

Heat exchange ventilation system not only helps you improve the indoor air quality, but also greatly reduces the load of air conditioning and saves the operating cost of air conditioning, so it is more and more favored by modern home design.
