The total heat exchanger can effectively recover the exhaust energy in the air conditioning system, and the core technology is mainly a heat exchange core. The working principle of the device is as follows: when the equipment operates, indoor exhaust air and fresh air respectively flow through the heat exchanger core in a positive crossing mode, and because of temperature difference and steam partial pressure difference of airflows at two sides of the airflow separation plate, the two airflows show heat and mass transfer phenomena when passing through the separation plate, so that the total heat exchange process is caused. When the air conditioner runs in summer, the fresh air obtains cold energy from air exhaust of the air conditioner, so that the temperature is reduced, and meanwhile, the fresh air is dried by the air conditioner, so that the moisture content of the fresh air is reduced; when the air conditioner runs in winter, fresh air is exhausted from the air conditioning chamber to obtain heat, the temperature is increased, and the fresh air is simultaneously exhausted from the air conditioning chamber to be humidified. Therefore, the fresh air is enabled to recover energy from air-conditioning exhaust through the total heat exchange process of the heat exchange core body. Meanwhile, the total heat exchanger is provided with an exhaust channel and an air inlet channel, the exhaust channel is used for exhausting turbid air in a building, the air inlet channel is used for introducing outdoor fresh air into a room, the outdoor air and the indoor air exchange heat and humidity energy, and meanwhile, the air exhaust can be recovered to the greatest extent, so that the environment protection and energy saving can be realized;
however, when the total heat exchanger in the prior art is operated, fresh air and exhaust air can be contacted in the heat exchanger core body to cause fresh air pollution, so that the total heat exchanger in the prior art cannot be applied to places with purification requirements such as hospitals and mushroom production factories in certain special fields.
