How to identify the effect of circulating water treatment system of the three hazards are scaling, corrosion, microbial algae, to identify the effect of water treatment services is based on the merits of these three aspects. "Industrial circulating cooling water treatment design specifications" (GB50050-95) gives several indicators: 1 open systems fouling resistance value:. 1.72 × 10-4-3.44 × 10-4m2K / W2 closed system. soil thermal resistance less than:. 0.86 × 10-4m2K / W3 corrosion rate of carbon steel pipe wall is less than 0.125mm / a4 copper, copper alloy and stainless steel corrosion rate is less than the wall 0.005 mm / a5 open recirculating cooling water systems. heterotrophic bacteria count of less than 5 × 105 个 / ml; slime less than 4ml / m3 water circulation system should be given water quality analysis report regularly, according to different dosing throughout treatment agent and water quality, there is a corresponding The reference index, the user can initially determine the treatment effect according to water quality analysis reports, and can use of coolant water bubble sheet test and chilled water, cooling water way coupons site monitoring. Central air conditioning, air-conditioned automatic mode, but the transformation is automatically set the indoor temperature, sleep mode or economy mode only energy saving. In fact, air power depends mainly on the "operation rate", when you start the most power, so do not frequently switch machines, and it is easy to wear and tear of the compressor. The increase was second-hand air-conditioned, and in 5 to 10 minutes before the open air temperature can be set to increase, maintain air can be more efficient. When the set temperature, and the outdoor temperature not much difference, such as outdoor 30 ℃, 25 ℃ indoor set on it. Such as that used central air conditioning does not cool the transformation of Xuzhou, can then set the temperature down a few degrees, so air-conditioned high-frequency operation time is short, power. Try to choose shady shady side of the room or rooms to install air conditioning, avoid direct sunlight on the air conditioner, it is best to hang a thick curtain, which can prevent the exchange of indoor and outdoor hot and cold air. Tightness of some better-conditioned room, shutting the windows to be to keep the cold air is not lost. Competition in the traditional areas has been unable to meet the business central air conditioning sales growth as expected, central air conditioning central air-conditioning energy transformation develop new applications market consensus. Meanwhile Xuzhou air conditioning maintenance and fluoride, with the continuous improvement of living standards and the gradual warming of the climate, most government departments, residents of the community, institutions and business units, and other construction sites are equipped with air conditioning. Central air-conditioning energy issues increasing attention. However, in the past it did not take into account the architectural design air conditioning electricity capacity, coupled with the need for a central air-conditioning energy-saving large sums of money, even if the intention of the unit managers to improve the central air-conditioning energy-saving air-conditioning Xuzhou hand air conditioning parts, but on the real economy The difficulty has become a stumbling block. In this case, Sky air-conditioning energy system into a common vision with the use of central air-conditioning manufacturing units. Very common recommendation in the field of construction, is the nature of infrastructure investment, construction and operation of a method.
