Fan coil units plus fresh air system is a widely used air conditioning system at present. It is widely used in hotels, hotels, office buildings, hospitals, and other buildings because of its flexible layout and independent adjustment of each room.
However, many problems are often caused by mistakes in construction and design, and the most common one is water leakage.

During the operation and use of the air conditioning system, the local stress is too large, or the supports and hangers fail, which is easy to cause slope change or local water storage, and it is easy to cause the overflow of condensed water.
It is necessary to strictly control the slope of water pipes, dredge the drainage pipes and control the reasonable spacing with other pipes during installation. Don’t get too close to prevent accidental stress and deformation.
And check the installation and fixing points of supports and hangers to prevent deformation and falling off.

Otherwise, there will be local water storage problems. These problems of fan coil unit air conditioning are easy to accumulate impurities, breed bacteria, moss, etc., and easily block pipelines for a long time. This kind of problem must be strengthened in construction management, and it is difficult to find and deal with it after the condensate pipe is insulated.
Every kind of equipment will have some shortcomings, and we won’t deny the existence value and use value of the equipment just because of its shortcomings. As long as we use them reasonably, they can be well used by us.

Reasonable use is limited and proper maintenance is indispensable. Therefore, it is necessary to establish a set of perfect maintenance management systems. Regular maintenance is an important link to improving the reliability of axial flow fan coil units.
According to the user’s experience, it can be judged that adopting different means and methods for different faults can significantly reduce the frequency and frequency of unplanned shutdown of the fan, so all these require the technology of axial flow fan coil unit to be more perfect and reliable.
As a fan coil unit manufacturer or supplier, you need to master simple solutions to deal with fan coil unit failures. Only in this way can we better serve our terminal users!
Such as surge, stall, high wind, etc., all belong to some fault problems.
To deal with the faults, maintenance personnel must know the operating conditions of equipment, analyze and judge the causes and frequencies of faults, quickly deal with the inducement that the oil pressure fluctuation affects the fan coil unit operation, and be familiar with the influence of the opening of wind rotor blades and stator blades on the fan coil unit operation.
In addition, when the nut used to fix the feedback bearing is loosened due to the vibration of the fan, the feedback rod will also fail.
The feedback rod can’t drive the jacket of the wrong oil valve to move, so it can’t seal the oil inlet of the regulating system. The fan coil unit blades can only slide in the direction of full opening or full closing and finally stabilize at the limit position by mechanical limit.
Although there are some unavoidable shortcomings in the axial flow fan, as long as we avoid these determinations well in use, the use effect of the fan can be well guaranteed, and the frequency of failures in use will be reduced a lot.
Causes and solutions of water leakage of fan coil unit:
1、If the water leaks out of the water collecting tray of the fan coil, it is mainly due to the problem of the thermal insulation material, which needs to be strengthened and can be eliminated.
The inlet and outlet pipes of the fan coil are well insulated
We just need to dredge the condensate pipe. Prepare a 4 ~ 5m long plastic pipe, insert one end into the condensate discharge pipe, and connect the other end to the bathroom faucet (you can make a small joint and screw it on the faucet by thread). Using the pressure of water, dredge the pipe or blow it with a carbon dioxide cylinder.
Note:
The phenomenon that the condensate pipe of the fan coil unit is blocked is frequent, which is mainly due to the existence of water in the fan coil unit, coupled with the appropriate temperature, which is easy to make algae multiply and grow, resulting in extremely thick gelatinous and slippery residue, which blocks the condensate pipe.
It is suggested to put algaecide in the water collecting tray of the fan coil unit to reduce its harm.
The water outlet of the fan coil unit is easily blocked
Fan coil air inlet is blocked

The condensate of the fan coil unit is often blocked because there is too much dust in the place where the equipment is located, and the drip tray is often polluted. In fact, the biological scale is basically environmental dirt.

Besides cleaning, the maintenance of the equipment is the most important thing.
