Passive building environmental control integrated machine (air conditioning system) with air supply volume ranging from 500 to 1200m 3/ h. The product integrates air conditioning, fresh air, purification, and dehumidification, with advantages such as low noise, high efficiency, energy conservation, constant temperature and humidity, and leading technical performance. It has passed the German PHI certification and is widely used in passive buildings (near zero energy buildings, ultra-low energy buildings) and basements.

The fresh air system (fresh air fan) is an independent air handling system composed of a supply air system and an exhaust air system. It can continuously discharge indoor polluted air, and filter and purify outdoor fresh air to evenly enter every corner of the room. Through systematic pipeline management, it ensures indoor air quality and brings a healthy and comfortable air environment. It is an essential equipment for home decoration in high-end residential areas, which is equally important for central air conditioning systems.

The fresh air system covers all categories and has built a complete product system, suitable for various engineering projects such as commercial housing, hospitals, schools, public places, etc. And customized services can be provided according to project requirements.

We can provide dehumidification, fresh air, purification and other operating modes according to the climate needs of different seasons. Automatically dehumidify according to the humidity value set by the customer, without the need for manual monitoring. At the same time, it has the function of purifying the air during circulation and dehumidification, making the air in the living space fresh and achieving appropriate sensory humidity.

Air energy heat pump is a new energy widely used after wind and solar energy. It does not emit carbon dioxide, does not produce harmful gases, and has a high energy efficiency ratio during operation. It is an energy-saving and environmentally friendly renewable energy product. The cost of heating the same weight of water in the same environment with an air energy heat pump is only one fourth of that of an electric water heater and two fifths of that of a gas water heater, which is lower than the comprehensive usage cost of a solar water heater with electric auxiliary heating.

The design of the combined heat recovery air handling unit strictly follows the national standard GB/T14294-2008, and has undergone several research and development upgrades. It not only has outstanding advantages in heat recovery technology, but also continuously surpasses and gradually rivals the industry's top in other design aspects. The newly upgraded "U" series units far exceed the corresponding standards in many indicators, and can be said to have excellent appearance and performance, with both appearance and strength.
