Ceiling fresh air unit is an air-conditioning equipment to provide fresh air. Fresh air is drawn in through the outdoor dedusting, dehumidified (or humidified), cooling (or heating) treatment into the room through the fan and so, replacing the existing indoor air when entering the interior space. Of course, the above-mentioned functions according to the needs of the environment have to be, the higher the cost function more fully. Ceiling fresh air unit frame structure used in all aluminum frame structure, the use of high-strength aluminum frame specific sections, each corner of the frame structure with special castings, profiles and connection angle plug-in structure, this structure has the following characteristics: A : mechanical strength, light supply wind chassis weight, corrosion resistance, appearance and size accurately. B: structural assembly and flexible, easy-to-spot disassembly, repair wind chassis models, and longer life than steel frame. Ceiling panels new air unit structure: A: Ceiling panels new air handling units with double color steel structure inside and outside, between two layers of steel punch injection for high-density polyurethane or polystyrene foam insulation materials other than glass wool insulation materials better insulation properties. In running various climatic conditions and the housing conditions were not cold bridge produce an edited selection of Notes, the air does not contain corrosive, viscous media can not contain. 2, medium temperature does not exceed 80 ℃, not lower than -10 ℃ 3, medium or hard-containing dust particles should not exceed 150mg / m3 4, be careful not to B-type fan used for firefighting purposes. 5, system design and fan selection should be made by professionals, and the system as much as possible to accurately estimate the negative force, otherwise it will lead to improper selection of the actual use of ineffective fan. 6, the pressure loss in the resistance component of the system is not a fixed value of the exhaust air box should be used to calculate the drag coefficient for selection. 7, the cabinet should not be in full form of the fan (ie the fan inlet and outlet pipes are not connected) under the long run, because in such a strong fan performance state is unstable, and in this case, the fan Standard configuration of the motor is in overload status, long-term use can lead to destruction of the motor, a short test drive is allowed.
