Features of the Ceiling Type Air Handling Unit
Structure
Box: aluminum alloy frame+color steel plate or polyurethane foam wallboard, with high air tightness and low air leakage rate.
Fan: low noise external rotor centrifugal fan, precise dynamic balance design.
Surface cooler: pure copper tube+hydrophilic aluminum foil to optimize heat exchange efficiency.
Air supply outlet: spherical nozzle with adjustable air supply angle (30).
Working principle
After the air is filtered and treated with temperature and humidity, it is pressurized by a fan to form a high-speed jet through a spherical nozzle, and then it is mixed with indoor air to realize long-distance uniform air supply.

Product advantage and Application
Product advantage
No need for air duct: save installation space and initial investment.
Efficient and energy-saving: jet air supply reduces cold and heat loss and operation cost.
Flexible adjustment: the nozzle angle can be adjusted to meet the needs of different seasons (such as cold air delivery and hot air sticking to the ceiling).
Quiet design: low noise operation (36-49dB).
Application scenarios
Industrial field: large workshops, warehousing and logistics centers.
Public buildings: airport, high-speed railway station, exhibition center, gymnasium.
Business places: shopping malls, hotel lobbies, ecological restaurants.
Equipment Maintenance Instructions
Daily maintenance
Filter cleaning: clean/replace the primary filter every month (dust accumulation will lead to a decrease in air supply).
Nozzle inspection: check whether the angle of spherical nozzle is offset, and manually adjust it to ensure the coverage of air supply.
Condensed water discharge: check whether the drainage pipe is unblocked every week, and clean up the water storage tray to prevent bacteria from breeding.
Regular maintenance (quarterly)
Fan inspection: clean the dust of the fan impeller, check the lubrication state of the bearing, and tighten the screws to prevent vibration and abnormal sound.
Cleaning the surface cooler: use a soft brush or a low-pressure water gun to wash the fins of the surface cooler to avoid blocking and affecting the heat exchange.
Electrical safety: test the insulation resistance of the motor (> ＞2MΩ) and check whether the terminal is oxidized.
Seasonal maintenance
Shutdown in winter: drain the water in the surface cooler to prevent the pipeline from freezing and cracking.
Before opening in summer: check the refrigerant pressure and valve sealing.
Safety precautions
Do not operate until the power is cut off, so as to avoid the risk of electric shock.Wear safety rope and protective gear when working at height.
FAQ
Q: What is the reason for the insufficient air supply distance?
A: The jet angle is not adjusted or the system resistance is too high. It is necessary to optimize the nozzle angle and check whether the air duct design is reasonable.
Q: What caused the excessive noise?
A: the fan impeller is eccentric or the bearing is faulty. Need to clean the impeller sundries, adjust the dynamic balance or replace parts.
Q: How to deal with condensate leakage?
A: It may be caused by no water seal on the drainage pipe or insufficient slope. It is necessary to add a water seal and ensure that the drain pipe is installed obliquely.
