Frequency conversion room energy-saving cooling scheme
Summer is the most easily heated season of mechanical equipment, to the current equipment control speed regulation indispensable frequency converter, hot weather is the hard damage of the frequency converter heat, a large number of existing studies and practice show that the frequency converter failure rate will rise with the rise of temperature, service life with the rise of temperature and decline, if the ambient temperature rises 10℃, the service life of the frequency converter will be halved.
Shandong Zhonglian Cement Co., LTD., founded in 2006, is an enterprise mainly engaged in non-metallic mineral products. The company's frequency conversion room plays a great role in the production task, and the proportion of new energy gradually increases under the "double carbon" goal, and the green low-carbon new energy system ushered in a new round of outbreak. Juxian Zhonglian Cement Company in order to better solve the problem of frequency conversion chamber cooling, and can actively respond to the requirements of "accurate energy saving and emission reduction" and "high energy efficiency green electricity consumption" proposed by the state and the government, and Changzhou Shibo En New Energy Technology Co., Ltd. to improve the frequency conversion chamber cooling system in the factory.
Frequency converter room construction area of about 44 square meters, the height of about 4.5m, frequency converter power 1000KW/10KV one, 560KW/10KV one; Kiln end inverter room construction area of about 30 square meters, height of about 4m, inverter power of 1400KW/400V one; When the inverter is working, the room temperature is as high as 42 ° C, and the fan is used to exhaust the air to the outside. When the doors and Windows are closed, the indoor negative pressure is large, causing the doors and Windows to be difficult to open.
Through the field investigation and combined with the cooling characteristics and theoretical calculation. There are 2 high voltage frequency converters and 2 cooling units in the converter room of kiln head. The inverter room at the end of the kiln has 1 inverter and 2 cooling units; The original duct ventilation mode of the two frequency converter rooms is changed to room temperature circulation mode, and the negative pressure of the room room is reduced to achieve the purpose of cooling. For general cooling, 4 photovoltaic air conditioning units are set to reduce the room temperature to achieve the purpose of cooling.
The construction of this project is a typical case of large-scale and low-cost comprehensive development and utilization of renewable energy, which is in line with China's plan to focus on cultivating strategic emerging industries of new energy, and is also the development of circular economy model. The concrete embodiment of building a harmonious society has a very great demonstration significance for promoting the development process of solar energy utilization, photovoltaic cell module industry and photovoltaic air conditioning industry.
Changzhou Superen New Energy Technology Co., Ltd. focuses on the development and production of solar air conditioning, solar energy saving products, through the manufacture and design of solar energy products to protect the environment, the company began in 2006, the product sales area throughout the world more than 30 countries and regions. We have always been committed to the improvement of product conversion efficiency, constantly strengthen the research and development of new technologies, improve the manufacturing process, dedicated to provide customers with high quality, high reliability, cost-effective solar photovoltaic products, and actively promote photovoltaic power generation, as soon as possible to achieve affordable Internet access.
