Special requirements for air conditioning units in civil/commercial areas:
Most residential and commercial occasions are inflated, and the size of the machine room is often compressed to a small extent. Therefore, the air conditioning box is required to fully consider the space constraints while satisfying the function. Due to the dense population in these occasions, the comfort requirements for the environment inside the building are relatively high. Although the equipment room is usually arranged in a sparsely populated area, the operation of the equipment still causes a lot of noise, so the noise requirements of the unit are controlled to a lower range. For high maintenance frequency, the unit must be easy to repair and easy to clean. In some cases, the owner did not design the machine room, the unit must be placed outdoors, so that the unit should adapt to the various bad weather outside. During the hoisting process of the unit, it is impossible to enter the site due to the limitation of the construction site. At this time, the unit must be segmented or even parts coming into the field. Civil and commercial air conditioning units sometimes have a wind volume of more than 70,000 m3/h. At this time, a higher-strength unit structure is required to accommodate large winds. Energy conservation is the development direction of air handling units. Residential, commercial and other buildings also require more and more applications of air handling units with energy heat recovery.

AL-KO AT4-Easyair/Smart solution:
1.Energy saving:High-efficiency heat recovery system (counter-flow swash plate heat recovery / high-density runner / counter-flow coil heat recovery) to ensure that the unit's heat recovery efficiency is over 80%.Low-resistance design for all components ensures minimum fan energy requirements.A large number of permanent magnet motor technologies with energy consumption levels up to IE4 (GB 1) are used to greatly reduce energy consumption.
2.Space saving:Unique non-standard flexible design ensures the smallest space occupied by the unit.Support for parts handling and on-site assembly.
3.Clean:Designed and manufactured in accordance with the world's most stringent hygiene certification requirements (VDI6022)
Its unique structural design allows the unit itself to meet hygienic conditions and avoid becoming a secondary source of pollution.
4.be quiet:Low wind speed design reduces wind noise and energy consumption.Internal and external 1.0mm steel plate structure ensures that the noise reduction of the box far exceeds domestic and international counterparts.A full spectrum noise data table is provided for each designed unit to facilitate the designer's design of the entire system.
