Nanjing Bo Shing Refrigeration Equipment Co., Ltd. is an independent subsidiary of Lead Sheng Machinery subsidiary, Nanjing University of relying on advanced technology, specializing in industrial temperature control equipment, industrial refrigeration equipment R & D, production, sales and service in one enterprise. With professional experience in production, leading production technology, excellent product quality and integrity of the business philosophy to first-class quality, it is the price, in the industry enjoyed a high reputation. The company has achieved a coincidence hair trustworthy Honor, Jiangsu AAA-class quality and integrity of brands, products passed the ISO9001: 2008 international quality system demonstration. The company attaches great importance to the product after-sales service, has set up a dozen offices in Shanghai, Guangzhou, Tianjin, Ningbo, Suzhou, Shenyang, Qingdao, Hangzhou, Chengdu and other places, fully address each customer's worries. Mistakes screw chiller operation Misunderstanding screw chiller operation prone: Before power is not closed shell and tube condenser inlet valve, this will result in the phenomenon of channeling water. Part of the cooling backwater flow away from the shell and tube condenser, thus reducing the cooling water flow shell and tube condenser, causing the unit condensing pressure rising, the host running current is increased, resulting in capacity loss, but also a serious screw chillers stop working. In this way, the costs of electricity, refrigeration efficiency and reduce equipment failure rate increases. Starting from the wrong operation, the host of the cooling water outlet temperature and condensing pressure. The unit will alarm, the operator will cause wrong judgment, that the cooling water is not enough, so the condenser cooling water pump inlet valve and outlet valve to open big, some cooling tower fan will be turned on, this will cause the cooling tower fan, and pump power consumption increases, the cost will increase a lot. Some operators even open the cooling water pump. To open the cooling water pump can reduce the condensing pressure and coolant temperature, pump operation of such electricity is wasted. Unit cooling water system the correct methods of operation are: a, before starting the closed shell and tube condenser inlet valve to prevent channeling water unit. b, open the valve and out of shell and tube condenser cooling water pump on, adjust the condenser inlet and outlet pressure. c, if the shell and tube condenser swing out of the water gauge pointer is too large, then there is air in the cooling water system, you need to vent gas within the unit until normal only after pressure gauge. Air-cooled chiller with water-cooled chiller air-cooled chiller installation works Compare air cooling mode, no other auxiliary equipment, eliminating the need for cooling towers, cooling water pump and cooling piping systems. Large air-cooled chiller belong outdoor models, can be placed on the building roof or outdoor aerodromes, without having to build another room. Small air-cooled chiller box is generally designed to be removable, according to the specific application requirements for indoor installation or outdoor installation, note that: air-cooled chiller is by cooling fan, so the environment has requirements such as ventilation, humidity, temperature can not be above 40 ° C and air pH and so on. For large Chiller proposed to provide room to ensure that the equipment including chillers, chilled water circulation pumps, cooling water pumps running and life, while in the building to the roof or to aerodromes placed outdoor cooling tower. Therefore, in the case of a building can not provide room, use air-cooled chiller is a more practical way.
