The total heat exchanger usually refers to a fresh air and exhaust air ventilation equipment containing a total heat exchange core. The total heat exchanger is a high-efficiency and energy-saving air-conditioning ventilation device. Its core function is to use the temperature difference and humidity difference between indoor and outdoor air. Through the good energy conversion characteristics of the energy recovery mechanism, it generates energy exchange while bidirectional displacement ventilation. So that the fresh air can effectively obtain the enthalpy value in the exhaust air, the full heat type CHA or the temperature sensible heat type CHB, which greatly saves the energy consumption of the fresh air pretreatment, and achieves the purpose of energy saving and ventilation, and its energy saving effect is very significant.
The working principle of the total heat exchanger is: when the product is working, the indoor exhaust air and the fresh air respectively flow through the heat exchanger core in a positive cross mode, due to the temperature difference and vapor partial pressure difference between the airflow on both sides of the airflow dividing plate, the two When the air flows through the partition plate, heat and mass transfer are present, causing a total heat exchange process. In summer operation, the fresh air obtains cold energy from the exhaust air of the air conditioner, which reduces the temperature, while being dried by the air-conditioning wind, which reduces the moisture content of the fresh air; in winter operation, the fresh air obtains heat from the exhaust air of the air-conditioning room, and the temperature rises. In this way, through the full heat exchange process of the heat exchange core, the fresh air can recover energy from the exhaust air of the air conditioner. https://www.sungroy.com/
