In the above technical scheme, the fresh air inlet and the return air outlet adopt scalable air ducts, which can be applied to different wall thicknesses and have the function of keeping out the rain. Wind short circuit.

In the above technical scheme, a metal filter screen is also installed in the air duct of the fresh air inlet to keep out mosquitoes and leaves.

In the above-mentioned technical scheme, the electrostatic precipitator can adopt the existing technology, such as the electrostatic precipitator for the indoor unit of the air conditioner produced by Changsha Yuanda Air Conditioning Co., Ltd., the electrostatic precipitator is arranged vertically in the casing with dust collecting plates, high-voltage ionization electrodes, Dust collecting plate, high-voltage ionizing electrode, dust collecting plate..., high-voltage ionizing electrode and dust collecting plate are respectively connected to the positive and negative terminals of the high-voltage DC power supply, and the dust particles entering the electrostatic precipitator are charged in the high-voltage ionization area of about 8000V. The principle of positive and negative particles attracting each other is adsorbed on the dust collection plate, and the strong electric field can break down the cell walls of bacteria, viruses and microorganisms attached to the surface of the particles and kill them, so that 99% of particles with a particle size ≥ 0.3 μm Respirable particles are filtered out, greatly purifying the air.

In the above technical solution, the plate heat exchanger can adopt the existing technology, such as Chinese patent 99232972.8 "Plate Heat Exchanger", or such as the plate heat exchanger equipment of Changsha Yuanda Air Conditioning Co., Ltd. The plate heat exchanger is directly composed of multiple plates, and there are gaps between the plates. The gaps on both sides of these plates become two isolated fresh air channels and return air channels, and this isolation is determined by the plate. The plate is isolated, and the plate is the conductor of the old and new heat exchange.

The utility model integrates three functions: indoor and outdoor exchange of old and new air, heat energy recovery and utilization in the process of exchanging new and old air, electrostatic dust removal to purify air, clever conception, novel design, unique technology and strong innovation. The exchange of old and new air is beneficial to improve indoor air quality, reduce CO ₂ , prevent indoor air pollution, ensure fresh indoor air, and benefit people's health; during the exchange of old and new air, plate heat exchangers are used to exchange heat at the same time, recovering 70% of heat energy , save energy, avoid room temperature fluctuations, human body feels uncomfortable, and ensure stable temperature regulation; the setting of the electrostatic precipitator can not only absorb dust particles in the air, but also kill viruses, bacteria, and microorganisms in the air, purify the air, Improve air quality. The utility model provides high-quality air equipment for people's daily life.
