Economic Effects of the use of total heat exchanger, first reflected in the health of people's attention, it plans to effectively address the people of high quality air quality requirements. Patient, is the human immune system, lower the resistance of the population. Air quality is directly related to the patient's recovery, air quality is good patient rehabilitation irreplaceable natural medical aid. Using the total heat exchanger, so that the patient can stay at home, the pipeline of new wind ventilators, you can enjoy nature and fresh, clean air heat recovery fresh air ventilation machine Product Description: XHB series heat recovery fresh air ventilation air volume: 300-5000m3 / h Pressure: 40-250Pa Features: The ceiling-mounted, ventilation and ventilation, can not take the heat to maximize the efficiency up to 70%, the built-in dust filter, new wind ventilators, effective to prevent dust and debris into the interior, energy saving, low noise, reliable operation, easy maintenance Application: open office area, hall, computer rooms, classrooms, factories, shopping malls, sports arenas, PBX rooms. First, the working principle When the indoor air conditioning return air and fresh air was positively flow through the heat exchanger core cross pattern, total heat fresh air ventilators, since the flat sides of the separator air flow and water temperature difference between the existence of vapor pressure difference, the two streams between heat and mass transfer phenomena presented simultaneously, causing a total heat exchange process. This process is accomplished by flat separator, so the case of the transmission type total heat exchange phenomenon. When installed on a system-wide heat exchange new fan runs during the summer months, commercial new wind ventilators, get fresh air from the air conditioning return air temperature decreases in cold makes while being air-conditioning return air drying, the fresh air to reduce the moisture content; in get fresh air from the air conditioner in Winter thermal energy return air temperature, and was air-conditioning return air drying, the fresh air to reduce the moisture content; get fresh air temperature thermal energy from the air conditioner is running in the winter when the air return, while being return air humidification , so that the new air moisture content increases, so recovering energy from the air conditioner return air by the total heat exchange process heat exchanger core of the new style.
