It's a flexible and typical solution for all building area, such as Mall, Office, Cinema, School etc. Indoor Unit Outdoor UnitProduct nameDX Purification Type Heat RecoveryAir Handling UnitsMaterialStainless steelFunctionHeat recovery,adjust cold/heat/humidityApplicationFactory,Mall,Restrant, Hotel,Hospital, School,etcFilter classG4+F7+H10Place of originBeijing,ChinaSelection Table of AHUWorking principle1/Both supply fan and exhaust fan are built inside tobring in fresh air and exhaust out the stale indoorair as well, thus to keep indoor space in naturalcomfort.2/Built-in heat exchanger (rotary heat exchanger orplate heat exchanger) transfers energy contained inthe outgoing indoor air to the coming fresh air,thus fresh air is precooled or preheated.3/Various functional sections such as filter section,cooling/heating section, humidifying section etc.can be combined together to meet different airtreatment requirements.Judging left or right typeLook at the direction of airflow supplied to indoor, it's left type if water pipes are located on the left side of the unit;otherwise, it's a right type. For standard AHU, service door, wiring port and water pipe locate on the same side.Main features1/ Up-down layer construction, concise, compact.2/ Rotary heat exchanger(RHE) as a basic part. Humidifying section, coil section etc. selectable as per requirements.Typical CombinationsCombination mode 1:Wheel + Coarse filter (medium filter) + Cooling coil (heating coil)+ Humidification + FanCombination mode 2:Plate heat exchanger + Coarse filter (medium filter) + Mixed air +Cooling coil (heating coil) + FanRotary heat exchanger (heat recovery wheel) is mainly used in building ventilation or in the air supply/discharge system of air conditioning equipment. The wheel transfers the energy (cold or heat) contained in exhaust air to the fresh air supplied to indoor.It's a piece of important equipment and a key technology in the field of construction energy saving.Rotary heat exchanger section1. Rotary heat exchanger is composed of heat rotor(wheel), frame, drive system, double purge sector and sealingparts etc..2. Supply air(SA) passes through half of the wheel, exhaust air(EA) passes through reversely the rest half of thewheel, meanwhile the wheel is rotating driven be the drive system. Thus, the wheel can be self-cleaning.3. Drain pan is equipped under the wheel, in case condensed water occurs from fresh air in summer or return air inwinter when their temperature is decreasing. Meanwhile, make sure the drainpipe is expedite and waterseal isinstalled.4. Ice jam might occur on the exhaust side when operating in very cold area, if so, rotary speed reduction or turn-onof bypass is required to ensure safe operation of the wheel.5. On some occasions with strict cleanness requirement, to minimize the carryover from return air to supply air,exhaust fan shall be placed in the leaving section of the exhaust side to create passive pressure, and the pressureshall be lower than that of supply side, so that the double purge sector can perform more effectively.6. For easy transportation or easy installation in limit space, the wheel can be cut into segments. FAN SECTIonWe offer different types of fans such as direct driven centrifugal fan, belt driven DIDW forward centrifugal fan, andbelt driven DIDW backward centrifugal fan etc.Holtop Factory
