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, ceiling total heat fresh air ventilators, air quality is good patient rehabilitation irreplaceable natural medical aid. Using the total heat exchanger, central air-conditioning fresh air ventilator, the patient can stay at home, you can enjoy nature and fresh, clean air for the heating time, the total heat exchanger with increased indoor humidity effects. Outdoor cold, dry, fresh air, because the original wet exhaust warm indoor air pollution cloud full heat exchange, so that the incoming air into a warm wet air. When cooling, the total heat exchanger has a reduced effect of indoor humidity. Outdoor fresh hot humid air, as with the original interior of dry, dirty air in the total heat exchange, so that the incoming air becomes fresh, cool, little humidity. All in all a total heat exchanger capable of indoor air excess moisture for fast drying. In 1m3 of air, for example, the actual mass of more than 1kg, bathroom, temperature 20 ℃, relative humidity of 80% 14g 1m3 air contains water vapor, new wind ventilators, it will condense on cold surfaces. In winter, when the outdoor air is 0 ℃, although still 80 percent relative humidity, but the water vapor content is only 4g, using the total heat exchanger per 1m3 of indoor air, water vapor can reduce 10g, while inhaled fresh air chamber preheat temperature from 0 ℃ to 15 ℃ floor-new wind ventilators, air conditioning Dingrui (certified), new wind ventilators Ltd. wucheng Dingrui provided by air-conditioning equipment. 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.
