Centrifuge market: technology is still the driving force for development

As China's urbanization progresses, large-scale projects continue to grow, and the demand for centrifuges is increasing at the same time. It is understood that more and more companies are currently investing heavily in the development of centrifuges. According to estimates by industry insiders, there will be a situation where males will fight each other in recent years. Domestic brands will pay more attention to the input of technology and break through the competition. Occupy more and more market share.

In the centrifuge market, whether it is past, present, or future, whoever wants to gain an advantage in the battle and stay ahead, is still relying on real technology. The demand for new technologies and new products in the market today is huge, the market needs fresh blood, and we are constantly researching and developing high-tech cutting-edge products. In addition, with the development of technology, the shape of the unit and the manufacturing process will also be higher. Claim. According to the Cooling Express reporter, in 1935, McQuay produced the first centrifuge and experienced many changes during the period. From semi-enclosed centrifuges to centrifugal heat recovery units, from double-compressor centrifugal chillers to the first centrifugal chiller with R134a environmentally friendly refrigerant in 1988, followed by frequency-converter centrifugal chillers and magnetic levitation-frequency centrifugal chillers , WME series magnetic suspension frequency conversion centrifugal chiller, 1500RT single head centrifugal chiller, 3000RT dual-head centrifugal chiller, WTC two-stage compression centrifugal chiller. “The average COP of the WTC two-stage compression centrifugal chiller this year is more than 6.7, which is higher than the ordinary products with higher energy efficiency and wider operating range. Under the conditions of ice storage, -5.6 degrees of water can be produced, and the temperature of the heat pump water can reach 65. In order to solve the problem that conventional centrifuges cannot operate stably under severe conditions,” Yu Qin told reporters, centrifuges are still a big market, and with the progress of technology, large-scale public construction projects and factory projects will still Prefer to choose a centrifuge.

“Future products are developing toward high energy efficiency, multi-functionality and environmental protection, such as 'magnetic suspension centrifuges' and 'heat pump centrifuges' that have emerged in recent years.” The staff of Midea introduced the energy efficiency coefficient of Midea’s frequency conversion centrifugal chillers IPLV up to 8.6, more than 30% energy saving throughout the year; excellent electromagnetic interference suppression design, product frequency conversion system through EMC, IEC, EN, UL and other electromagnetic compatibility certification; no start-up current impact. The frequency conversion centrifugal heat pump unit is a high pressure specific compressor designed for water source heat pump operating conditions, with 1.5 times the surge margin of ordinary centrifugal chiller units, to achieve a wider range of water temperature adaptation; using adjustable electric control valve The design can accurately control the degree of superheat, can speed up the regulation speed and increase the partial load energy efficiency; configure the check valve of the compressor exhaust to prevent the compressor from reversing, prevent the compressor from surging, and improve the safety.

This year, Johnson Controls York Air-Condition launched the YMC2 Maglev frequency conversion centrifugal chiller at the China Refrigeration Exhibition. According to York staff, "The YMC2 has a cooling capacity of 200-400 tons. It incorporates Johnson Controls' most advanced core technologies, including magnetic bearings and permanent magnet motors, OptiSound noise control technology, OptiSpeed ​​inverter drive technology, and OptiView diagrams. As the control center and falling film evaporator technology, it is understood that through the application of these core technologies, first of all, the YMC2 can significantly improve the unit's full load and part load efficiency, and improve its performance by more than 10% over conventional centrifugal units. All-weather operating efficiency. Secondly, its high tightness design, oil-free lubrication, and falling film evaporators significantly reduce the refrigerant charge and other technologies that help reduce the direct impact on the environment. At the same time, it reduces energy consumption and reduces carbon emissions. It can be even more efficient. Good protection of the environment. In addition, its unique design allows the unit to operate at an unbelievably low noise level. The noise measured under the AHRI575 operating conditions is equal to or lower than 73dBA, which is the highest level in the industry.

At the same time, Gree staff said: “The Maglev centrifugal chillers independently designed and manufactured by Gree in 2011 have officially gone offline and have been publicly displayed. According to national accredited lab data, Gree Maglev centrifugal chillers have the highest energy efficiency ratio. 16, Compared with ordinary centrifugal chillers, it can save more than 40% energy. The noise of the whole machine is less than 70dB, which is lower than the noise of screw chillers. It is in full compliance with the requirements of the country's green building and energy conservation and environmental protection."
