Semi closed piston compressor enters a new stage of game, do you understand?

Insiders pointed out that with the gradual standardization of China's compressor industry, the market competition is becoming increasingly fierce, and the polarization is beginning to take shape. There is not only a dispute between brands of semi sealed piston compressors, but also a dispute between scroll series and screw compressors. At present, there are many piston compressor enterprises active in China's refrigeration market, such as bizel, Foxconn, duling, raffkang, Bock, Zhejiang Daming, Suzhou Lixi, bolette, Jiangsu Huarui, Zhejiang Commercial Machinery Factory, Shenyang shenyileng, Taizhou Jingwei, Jinhua walker, Jiangsu Xuemei, etc. If the data of enterprises such as bizel, Zhejiang Daming, Foxconn, lefkang, GEA, bolette and Lixi refrigeration grow steadily, it is bound to seize the share of other brands when the overall market demand changes little. Therefore, industry experts predict that the polarization of semi closed piston compressor brand is becoming more and more obvious. "The competition in the compressor market is fierce. After the screening and precipitation of the market, all compressor manufacturers will show their original shape, and it will be clear at a glance whether they can or not. There is a saying that long-distance running depends on endurance." Xie Xinjiang, chairman of Zhejiang Daming refrigeration, pointed out that after fierce competition, the industry may "shuffle", and the choice of the market is always smart. At the same price, there is a higher quality option; With the same quality, there are better services and policy options. In the future, the product competition will gradually transform into the pursuit of higher fields such as performance, reliability, energy conservation, environmental protection and service. At this time, what enterprises should do is to improve quality and service. In the face of competition, Bizel discusses from multiple perspectives: "There is no shortage of market competition, but enterprises must first achieve benign competition on the premise of independent intellectual property rights; from the perspective of market demand, the bigger the cake makes customers selective changes, but enterprises with long-term planning will continue to compete for a long time only if they really start from customer demand. Each product has its own applicability, and giving full play to its advantages is the key; in addition, with the proposal of the goal of carbon neutralization and carbon peak, good enterprises should also Have a sense of market responsibility, which is also the focus of many end customers when choosing. " In addition, in the refrigeration compressor market, the competition among piston, scroll and screw is fierce. Piston compressor competes with scroll and screw compressor in the small cooling capacity range and large cooling capacity range respectively, especially in the small cooling capacity range. Scroll compressor continues to erode the market share of piston compressor by virtue of its advantages in energy efficiency, volume, noise and price. Based on this, insiders determine that the semi closed piston compressor will still be in a stable development trend in the next few years, and the fluctuation will not be too large. According to the analysis of Mr. Ivan, the person in charge of Fuji Howe China: "I agree that the market share of piston machines is eroded by the vortex machine and screw machine market, but I firmly believe that the piston machine market will not shrink, but will continue to occupy a certain market share. The theoretical logic behind it is that at low evaporation temperature, the COP value of piston machines is higher than that of vortex machines, and the cost performance of piston machines within 30HP is much higher than that of screw machines. Fuji Howe can still foresee a similar growth trend in the next 2-3 years. ”

The technical standard defines the evaluation benchmark of green (Design) products of fully enclosed scroll refrigerant compressor for the first time

Fully enclosed scroll refrigerant compressors are widely used in domestic and industrial air conditioners (heat pumps), heat pump water heaters (heaters), refrigeration and other fields. The supporting downstream products mainly include unit air conditioners, multi on-line, modular machines, water (ground) source heat pumps, automobile air conditioners, etc. they are used in many industries of people's life and society. They are the main energy consuming components of air conditioning products. Promoting and implementing the green design of fully enclosed scroll refrigerant compressor products is of great significance to the realization of green emission reduction and "double carbon" goals in the manufacturing industry! Recently, approved by the Standardization Working Committee of China Society of mechanical engineering, the standard of green product evaluation specification for fully enclosed scroll refrigerant compressor (T / CMEs 20002-2022) was officially released. The standard was organized by the fluid engineering branch of China Society of mechanical engineering and led by Hefei General Machinery Research Institute Co., Ltd. The standard was officially implemented in February 2022. Based on the concept of green design, analyze and evaluate the energy consumption, resource consumption and environmental impact of products in the whole life cycle of design, manufacturing, testing, use and waste treatment, implement the ideas and principles of effective utilization of energy, rational utilization and recycling of resources and utilization of advanced energy-saving technologies, and control energy consumption, resource consumption, emission and pollution from the source, Achieve the goal of energy conservation and emission reduction. Fig. 4 fully enclosed scroll refrigerant compressor is widely used The technical discussion and practical research on the green design of industrial and commercial refrigerant compressors in China started late and has not been improved. At the current time of the vigorous development of China's refrigeration and air conditioning key component industry represented by fully enclosed scroll refrigerant compressors, we should start to promote its green product evaluation, and then guide the planning and R & D according to the green requirements in product design, so as to strictly ensure the complete green characteristics of products. The technical standard specifies the evaluation requirements and evaluation methods of fully enclosed scroll refrigerant compressor as a green product, which is applicable to the fully enclosed scroll refrigerant compressor for steam compression refrigeration system driven by motor (the electric scroll air conditioner compressor for new energy vehicles can be used for reference), and defines the pollutant emission, quality management, environmental management and other systems, advanced technologies and processes of production enterprises According to the basic requirements of green supply chain management, four first-class indexes of resource attribute, energy attribute, environmental attribute and quality attribute of fully closed scroll refrigerant compressor are put forward; Decompose one or more evaluation criteria at the next level, and put forward the evaluation criteria at the next level. Among them, the resource attribute includes three secondary indicators: the content of harmful substances in products, recyclable marks, packaging and packaging materials; The energy attribute corresponds to the secondary index of refrigeration performance coefficient; Environmental attributes include renewable utilization rate, refrigerant type, refrigerant recovery, noise and vibration; Quality attributes include secondary indicators such as refrigerating capacity, input power, moisture resistance, electrical strength, protection of easily accessible live parts, leakage current and so on. The technical standard defines the evaluation benchmark of green (Design) products of fully enclosed scroll refrigerant compressor for the first time, and solves the problem of the lack of green product evaluation system of fully enclosed scroll refrigerant compressor. It is of great significance to improve the green manufacturing standard system of key components of refrigeration and air conditioning industry in China and advocate the full life cycle evaluation of social energy products.
