Seepage ceiling fan coil air conditioning system fan coil air-conditioning system is the most the most common problems in summer. Ceiling seepage only affects the appearance, serious also affect the normal use of the room and increase maintenance costs. There are many reasons for seepage produce, here are some common phenomenon.
1.An insulation layer disposed failed
Chilled water fan coil system is supplied from the chiller, the water temperature is usually only about l0 ℃, so the unit's water supply pipe, return pipe, condenser and condensate drain pan temperature are lower than the dew point temperature of the room, it is easy to appear in the summer knot Lucy, it is necessary to insulate the pipe. When installing insulation requirements between the wall and not leave gaps, but also to the materials requirements are also higher. The actual project, by itself or due to insulation material of construction, thermal insulation materials failed to close on a wall or pipe, so that there is a certain gap between the insulation material and the tube wall, when the air enters the gap with cryo tubes wall contact, they produce condensate, condensate water piled up, it will have ceiling seepage. Such as the use of glass wool insulation shell in some irregular pipe at the insulation and pipe fittings difficult to close after the pipe surface is easy to produce condensate water suction pipe and casing, the entire glass wool shell absorb enough water condensation water will seep the soaked ceiling. The project is also due to the condensate water without making the insulation, thereby forming a secondary condensate in condensate water, wet ceiling.
Now, with economic development, water, air-conditioning systems in many buildings are beginning to use rubber insulation materials. Such material is material structure, thermal conductivity, surface heat transfer coefficient, have a resistance to water vapor permeability coefficient of great advantage in terms of construction is more than glass wool, especially for irregularly shaped pipe fittings and valves insulation , due to reduced construction causes condensation dripping
2. condensate water pipeline does not have a slope or incline setting does not meet the requirements of many developers now use for their own interests to reduce storey building way to reduce costs, resulting in generally low-storey building, reducing the space inside the ceiling, this air conditioning system duct, pipe arrangement is extremely unfavorable, especially condensate water pipeline. Condensate is discharged by the condenser fan coil slope to achieve, and often focus on emissions, if the space on the ceiling does not meet the requirements of the condensate water pipe slope, it will cause no slope or even anti-slope enable drip tray the water did not break out, resulting in the overflow after the expiration, causing the ceiling water seepage.
In addition, if the PVC hose as a condenser, in a long line due insufficient stiffness can not guarantee the drainage slope. In response to this phenomenon, in the design and construction, the specification must be strictly enforced to ensure that there is sufficient slope fan coil condenser. In the selection of the material can be taken in place of the vinyl chloride galvanized steel hose connected to the condensate water in part of the bellows. When the story is too low can not meet the grade requirements, you can take the condensate drain pipe from centralized to decentralized way drainage patterns, the condensate water drains connected to each room
Domestic water drains between.
3 condensate water piping diameter is too small
Fan coil air-conditioning system of the condensate system is a non-pressure system, so the size of the diameter of the condenser condensate will directly affect emissions. If the condenser tube diameter is too small, it will lead to increased resistance along the condensed water discharge failure, caused the leakage phenomenon. So in the design process must condenser fan coil diameter between the load (and the room load) to determine the correspondence between the condenser and diameter according to the design manual, but also construction units must strictly follow the construction plans to purchase materials and construction.
4 condensate water drain blockage summer air-conditioning fan coil room mostly wet condition work coil surface is often covered with dust, if not timely cleaning maintenance personnel, will make the dust or fibrous materials are some small condensate washed down, deposited condensate pan, and humid environments condensate pan will cause bacteria to produce a gum dirt, thus clogging the drain caused by condensate spills. You can now take the form of condensate water once stretch forming, the use of condensing water outlet groove formed in the molding process to ensure the smooth flow of condensed water discharge, and should be checked regularly for fan coil cleaning.
5 Other
(1) fan coil air conditioning system design, the new system uses wind does not undertake indoor moisture load or load new rheumatoid coil borne by the way, and in the design of the condensate water pipe did not consider this case, the choice of condensate water pipeline too small, resulting in condensate spills.
(2) Some designers when making design load, in order to secure a large selection of well-off factor, which would cause the temperature of the air-conditioned room temperature is lower than the design, supply and return water temperature of the coil is reduced, increased condensate produced, and condensate water pipe in accordance with standard design cause condensate spills.
Poor quality
(3) pipe valves and other equipment, leak itself. To solve the above problem, each design and construction personnel must strictly comply with national standards and norms, the choice of high-quality equipment and materials to solve the problem of water seepage from the ceiling at all.
