The central air-conditioning system needs to consume a large amount of energy, and its energy consumption accounts for about 60% of the total energy consumption of the entire building. Therefore, the air-conditioning system needs to save energy and save operational investment. The reasonable choice of suitable insulation materials and strict control of insulation construction are important ways for air-conditioning systems to save energy. The main performance indicators of insulation materials are the following: thermal conductivity, density, moisture resistance factor, fire performance, installation performance, etc.
1, thermal conductivity
The thermal conductivity is a basic index to measure the quality of insulation materials, determines the insulation properties of materials, generally less than 0.2W / (m? K) materials can be used as insulation materials, GB/T 17794 clearly stipulated: 40 °C, insulation materials The thermal conductivity is not more than 0.041W/(m?k); at 0°C, the thermal conductivity of the insulating material is not more than 0.036W/(m?k); at -20°C, the thermal conductivity of the insulating material is not more than 0.034W/(m) k). At the same time, the thermal conductivity coefficient is also an important parameter to determine the thickness of the insulation layer. When the pipe insulation thickness is improperly selected, condensation water will be generated on the outer surface of the insulation layer, which will cause drip on the surface of the air pipe, seepage of water in the ceiling, and mildew, which will seriously affect the indoor air supply environment.
Currently, the third generation of rubber foaming technology is commonly used in the market. When the air-conditioning insulation material is at 0°C, the thermal conductivity is as low as 0.032W/(m·k), which can effectively block the heat and cold of the air-conditioning piping system and the external environment. exchange. With Ducan's professional selection calculation and professional installation and guidance team, it can ensure zero condensation of the entire system.
3, damp resistance factor
The wet resistance factor is a key indicator to measure the water vapor penetration resistance of insulation materials and determines the service life of the material. GB/T17794 clearly stipulates that the moisture resistance factor μ of the insulation material is not less than 1500. With the increase in the number of years of use, the material with a smaller moisture resistance factor is more likely to infiltrate into water vapor, leading to a sharp increase in the thermal conductivity of the thermal insulation material, and thus losing the thermal insulation effect. Therefore, open-hole insulation materials such as glass wool, etc., need to be provided with a moisture-proof layer to extend the service life of the material.
The air-conditioning insulation material using the third-generation rubber foaming technology has a fully-closed structure with a moisture resistance factor of 10,000 or more, virtually eliminating water vapor infiltration and ensuring a stable thermal conductivity over a long period of time.
3, fire performance
The fire performance standard is the basic requirement for the safety of the use of insulation materials, and the fire protection requirements for the pipeline insulation materials must reach the flame retardant B1 level. The use of insulation materials with poor fire performance may leave potential safety hazards for the entire central air-conditioning system. Once a fire occurs, the fire may spread quickly, causing huge economic losses.
4, installation performance
Installation performance is an important factor in determining construction efficiency and construction quality. Insufficient selection of insulation materials can seriously affect construction progress and construction quality. Improper installation may also cause condensation water to form in the system. Therefore, it is important to choose a suitable and easy-to-install insulation material.
To sum up, the central air-conditioning system selects suitable insulation materials to comprehensively consider various aspects of performance indicators. The types of insulation materials in the market are inconsistent, and the performance indicators of the materials must not be neglected in pursuit of price, which affects the normal operation of the system. In the trend of building energy-saving and green building, we choose Dukan high-quality rubber and plastic insulation materials to make the central air-conditioning system more durable, more energy-efficient, more environmentally friendly and safer.
