The difference between the total heat exchanger and new wind ventilators new wind ventilators built sensible heat exchanger or total heat exchanger, the discharge portion of the outdoor air energy recovery, energy consumption does not increase too much the room. New interior features are mandatory "old" style full replacement of the heat exchanger advantage, only a simple exchange of energy between the new "old" style. Air duct can be understood as two-way, all the way to a new style, all the way to the indoor "old" style. Commonly used in a small space applications, such as family, hospital wards and small meeting rooms. After the new unit is the use of hot and cold air outside air source heat moisture treated centrally air-conditioned terminal equipment, new air handling to set the temperature and humidity into the room. Air duct has only one fresh air. Common space or room for large venues such as auditoriums, a layer of hotel rooms and the like. Total heat exchanger is used in such new wind ventilators or combined air conditioner of a component, with additional fans to complete part of the heat and moisture exchange between the two Lu Feng, both the transfer of energy between the two Dalian Lu Feng the total heat exchanger, there are transfer quality. (Sensible heat exchanger energy transfer between only without the transfer of the quality of) the principle of total heat exchanger total heat exchanger is an energy efficient air conditioner ventilation system, its core function is to use indoor and outdoor air temperature difference and humidity difference, recovering the movement of the transducer characteristics by good energy, at the same time two-way displacement ventilation, resulting in energy exchange, making effective access to fresh air exhaust air enthalpy total heat type CHA or temperature sensible heat type CHB, which greatly energy saving air pretreatment, to achieve the purpose of energy saving ventilation, energy saving effect is very significant. _ Dingrui full advantage of the heat exchanger and air conditioning (certified) _ a total heat exchanger by wucheng Dingrui Air Conditioning Equipment Co., Ltd .. Wucheng Dingrui Air Conditioning Equipment Co., Ltd. (www.wcdrkt.com) (www.wcdrkt.com) is an industry leader in Shandong Dezhou, fans, ventilation equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness , the maximum meet customer needs.
