With the continuous improvement of people's living standards and the rise of science and technology, simply speaking, the full heat exchanger is to achieve a replacement of indoor and outdoor fresh air and old air through its own motor, in the replacement process, because it carries its own filtration and heat recovery functions, so today the full heat exchanger will take you to understand!

1, paper core full heat exchanger:

When indoor air conditioning exhaust air and outdoor fresh air flow through the heat exchange core body in a cross type, because the gap between the fibers is very small, only water vapor molecules with small particle size can pass through, and other harmful gases or odor gas molecules with large particle size can not pass through, so as to achieve the exchange of temperature and humidity.

When running in summer, the fresh air obtains cold energy from the exhaust air of the air conditioner to reduce the temperature, and the water vapor in the fresh air penetrates into the fresh air under the action of partial pressure.

When running in winter, the fresh air obtains heat energy from the exhaust air of the air conditioner, so that the temperature rises, and the water vapor in the exhaust air penetrates into the fresh air.

2, evaporative aluminum core full heat exchanger:

The unit adopts a static cross-flow heat exchange core body, the core body is supported by hydrophilic aluminum foil, and consists of several layers of heat exchange units. The flow channels of the two adjacent layers of units are cross-arranged. The principle is that indoor exhaust air is introduced by the fan, and the indoor exhaust air is humidified by the evaporation and heat absorption of atomized water before passing through the heat exchange core body. The indoor exhaust air reaches the air state close to the wet bulb temperature, and the air temperature of the indoor exhaust air is lower than the dew point temperature of the outdoor exhaust air. Then, the air passes through the heat exchange core body in a cross way with the outdoor fresh air. The heat is transferred from the high temperature side to the low temperature side through the heat transfer partition, and the heat exchange is then sent to the required room by the air duct.

Therefore, in the replacement process, the air will be filtered, the harmful substances in the air such as dust, haze, bacteria and other macromolecular substances will be filtered, and the indoor heat can be recovered when the indoor pollution is discharged, and the energy saving effect will be achieved.
