Air handling unit drawing

General comfortable occasion air handling unit
Configuration of basic function, early efficient filter and hot coil in air handling units (choose wet membrane humidification), it has the simple and highly controllable size characteristics of the function.
Suitable for general building room comfort air conditioning process.

Air handling units for all fresh air occasion
Configuration of basic function, primary filter or medium efficiency air filter, cooling coil ( enough margin, meet the needs of extreme conditions), it use steam, hot water heating, or natural gas direct combustion heating section
( high thermal efficiency, low running cost); it also need to set the reheat, can choose the cooling reheat to control humidity and enhance the energy level, or set up the electric heater, to realize thermal compensation again after the summer dehumidification. It mainly meet the aerospace, automotive, instruments and meters, precision machining and other special industry requirements for air quality.


Air handling units for general technology purification occasion
The configuration of the function section are: mixed section, cooling section, fan section, primary efficiency filter (G4) section, medium efficiency filter (F8) section. At the same time,it equipped with electric heating, electric humidification, muffler to satisfy high cleanliness, constant temperature and humidity,low noise control cleanliness project. Such as: inspection and quarantine laboratory, electronics factory workshop, biological engineering R&D center, food processing, precision machinery, pharmaceutical processing and storage area and other places which have strict requirements for temperature and humidity, cleanliness.

Air handling units for general technology purification occasion
In addition to the general horizontal units, we can provide several kinds of structure forms of units, such as: vertical, ceiling, roof waterproof, etc.. They can meet the demand of different occasions. Ceiling structure unit can be installed on the ceiling. It is suitable for narrow room air conditioning or the area which has not a special equipment room;Roof waterproof structure unit can be installed on the outdoor roof or outdoor floor. Setting rofessional rainproof device and panel special thermal insulation design unit.

Air handling units for operating room and high clean requirement occasion
In addition to the basic function of configuration, with primary efficiency filter or medium efficiency filter, it equipped with electric heating and humidification section. Considering particularity of medical situations, AHU adopt double cold source system ( chilled water + direct expansion) and efficient unhoused centrifugal fan, provide frequency conversion control, in order to satisfy the high reliability requirements.

Air handling units with heat recovery device
Can configured with wheel heat recovery device, hot and cold air passes through hot wheel, heat and moisture exchange is carried out by the difference of temperature and steam pressure between fresh air and exhaust air, effective recovery of sensible heat and latent heat in exhaust air, achieve the purpose of energy conservation.Honeycomb structure with aluminum foil carrier and high efficient moisture absorbing coating for heat storage core body of heat exchanger, excellent characteristics of heat storage, moisture absorption and heat transfer, efficiency is higher than 75%.

Can configured with plate fin heat recovery device, so that the cold hot air flow directly through the same heat exchanger, in order to achieve the purpose of heat exchange.The heat exchanger adopts ginning aluminum foil,  corrugated aluminum foil heat exchanger made of heat conductor, no interme-diate heat medium is required,no power consumption,no loss of temperature difference,temperature efficiency is higher than 75%.
