Central air conditioning system requires a lot of energy, building energy consumption accounts for about 60% of total energy consumption, and therefore requires air conditioning system needs to save energy central air conditioning installation, save operating input. The reasonable choice of insulation material thickness and product, as well as strict control of insulation construction is an effective way to energy-efficient central air-conditioning system. In addition, installation of central air conditioning, mostly office buildings, hotels, shopping malls and other large and medium and high requirements. Air-conditioning insulation directly related to the central air-conditioning wholesale everyday use, fire performance and initial investment, and thus the need for insulation selection and construction enough attention. Such as central air-conditioning agents, conditioning system if the insulation problems in the operation of central air conditioning may be condensation, resulting in water dripping ceilings, walls of water seepage moldy, seriously affecting the perception and use of functions, and cause some economic losses.
