The water pipes and air pipes of the air conditioning system should be insulated with adiabatic insulation materials, whose purpose is nothing more than to reduce cold (heat) loss for energy saving and ensure the temperature and relative humidity required by the clean workshop. The second is to prevent condensation and dripping of air conditioning pipes and cold water pipes in summer. Generally, the suspended ceiling of clean workshop is soft ceiling (color steel plate or other light plate). When the dew dripping from the air duct flows to the ceiling, it will leak into the clean workshop and affect the normal operation of the workshop. If it is a civil office building, hotel and other public buildings, because the cold water pipe and air supply pipe insulation is not good dew dripping, soft ceiling can be seen wet, print a piece, ugly.

What about dew dripping in clean workshop

Therefore, do not underestimate the problem of air conditioning duct (water pipe) insulation, not to solve the problem is infinite, if the problem is difficult to spend more money to repair. Especially in July, August and September, the rainy season is very concentrated in recent years. Most of these clean workshops with dew and dripping water have problems one year after delivery.

How do you solve the dew problem?

The solution to this problem is mainly from two aspects, the first is to solve the performance of thermal insulation materials and insulation layer thickness; The second is to solve the ventilation problem of the technical interlayer of the pipe on the ceiling.

** is the performance of thermal insulation materials and insulation layer thickness problem: at present, there are many kinds of thermal insulation materials sold on the market, thermal insulation performance is not the same, the price is also high and low. Generally, non-combustible thermal insulation materials are rock wool and glass wool, etc.; Commonly used refractory insulation materials are polyethylene (PEF) and rubber and plastic. When rock wool and glass wool are used for cold pipe insulation, aluminum foil must be used as a moisture-proof layer (protective layer). If the moisture-proof layer is not properly treated or damaged, the moisture in the air will dewdew into the fiber and make the insulation material ineffective. And polyethylene and plastic closed cell foam has better insulation performance, but the market of various suppliers of polyethylene and plastic sales, in order to compete at a low price product quality is difficult to ensure. Sometimes when the contract is sent to the sample and a large number of thermal insulation materials delivered thermal insulation performance and flame retardant and tide insulation performance is far from the guarantee of quality.

The second is the ventilation problem of the technical interlayer of the pipe on the suspended ceiling: practice has proved that the technical interlayer of the pipe on the suspended ceiling must have ventilation facilities, and the condensation phenomenon of the stuffy top is more serious if there is no ventilation. The condensation phenomenon of the technical interlayer near the external window is less and less serious, and the condensation phenomenon is more serious if the technical interlayer is further away from the external window. The ventilation of the interlayer of the pipe technology on the ceiling can adopt natural ventilation (open external Windows) or mechanical exhaust air and natural intake air. If the technical sandwich area is large, the above solution can not solve the problem, but also can use the mechanical ventilation opposite the mechanical exhaust air.
