Shanxi Lung Preservation Technology Development Co., Ltd. was established in 2002, Shanxi Academy of Agricultural Sciences, Institute of Science and Technology under the storage and preservation of agricultural enterprises, but also the National Agricultural Science and Technology Park (Taiyuan) enterprises in the park. The company is the vice president of Shanxi Province, Refrigeration and Air Conditioning Industry Association unit, with refrigeration equipment installation and maintenance of B qualification, can undertake the total cost of five hundred million less refrigeration, air-conditioning equipment installation, maintenance. Atmal MS51 MCU control system closed loop operation, the storage temperature T by the sensor into a current, the transfer converted to voltage and amplified, filtered, and then the A / D conversion, filtering software, and storage temperature to obtain the corresponding temperature T digital signal. On the one hand the temperature LED display for duty staff sent to observe and send logger print, on the other hand compared with the set temperature value calculation, CPU issued based on the comparison of corresponding Treasury cooling, forced cooling, power failure or power outage, thereby opening or closing solenoid valve for cooling, forced cooling, refrigeration and other related operations cease, and can adjust according to the number of compressor on the power required, filter design, both reached the destination library precise temperature control, but also to achieve energy saving effect. Generated by the MCU clock timer interrupt, timer scan five channels, each library were sharing control room work in different working condition. Installation of ventilation equipment in different ways depending on the cooling and ventilation equipment ventilation blower-type two. 1) The fan tripod fixed on the housing flange, and installation should be done to keep the level of fan blades, motor shaft vertical, Fangshan filters, radial blade tip clearance and the casing around the uniform, the distance not less than 10mm, blade mounting angle should be the same. 2) The induced-draft cooling towers, filters wholesale, motor cover and the rotor should be a good waterproofing. Usually enclosed cage asynchronous motor, after the motor turn normal again, should motor terminal box or other moisture-proof material with epoxy sealed to prevent the motor from moisture. 3) The forced draft cooling towers to prevent splashed droplets fans distance between the fan and the cooling tower is generally not less than 2m. Filter processing, preservation Shanxi Lung (online consultation), Fangshan filter provided by the Shanxi Lung Preservation Technology Development Company Limited. Shanxi Lung Preservation Technology Development Co., Ltd. (www.sxltbx.com) is Taiyuan, heat, refrigeration and air conditioning equipment leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customers needs. Lung preservation of leadership in Shanxi with the staff warmly welcome all inquiries negotiations to create the Shanxi Lung Preservation better future.
