Future trends of semi-hermetic screw compressors? Unseen companies may be eliminated2

Future trends of semi-hermetic screw compressors? Unseen companies may be eliminated From single-screw to single-machine two-stage, from ordinary type to frequency conversion, environmental protection, energy-saving type, from a single product to the provision of system solutions, the development of semi-hermetic screw compressors has never stopped and has continuously penetrated into major refrigeration projects. What are the new trends and opportunities for semi-hermetic screw compressors in the future? How can companies take advantage of these trends and opportunities? Mr. Bizeltembo believes: "It is what companies should see to combine the advantages of products and market demand for targeted research and development. In addition, the establishment of a better service system and service network is also one of the companies to grasp the market. key point." Bitzer has launched many product series in the large-scale products of low-temperature screws in recent years, mainly for the needs of large-scale commercial freezing and industrial freezing projects; at the same time, the developed frequency conversion screw also provides more energy-saving aspects. Selection method; in the field of high temperature, Bitzer introduced a more economical screw machine suitable for fresh-keeping applications such as fruits and vegetables. Okmarts.com pointed out that the national standard public building energy-saving design standard gives the integrated partial load factor (IPLV) of the refrigeration and heating units. For the current refrigeration and heat pump equipment is not running at full load for a long time, in order to be able to actually react to the operation of the unit For energy efficiency, the AHRI Institute of HVAC Engineers proposed the concept of integrated partial coefficient (IPLV) to measure the energy efficiency of the unit under partial load. Based on the market trend of environmental protection and energy conservation, to meet the operating conditions under partial load, the energy efficiency is optimized, and it can meet the national standard GB19577 standard IPLV energy efficiency rating index water cooling first-level standard. For China's current promotion of environmental protection and energy conservation, okmarts.com continues to contribute to energy conservation and environmental protection Work hard to meet the needs of energy saving. A&S believes that as a general fluid machine, screw refrigeration compressors are only one component in the compressor unit, and the compressor unit is only a part of the refrigeration project. The refrigeration project is still only a subsystem in the entire cold storage project; screw refrigeration compressors Relative to traditional machinery, it is another field. If the screw machine project is operated simply according to the model of a machinery manufacturing enterprise, it is often not feasible. It is difficult to understand the application of screw refrigeration compressors but not mechanical manufacturing. To provide cost-effective, stable and reliable products, the phenomenon of international swarms is very serious, and screw compressors, as a product with a high manufacturing & application technology content, need to integrate the capabilities of cross-professional teams and succeed in combining reasonable products and market strategies. ; It is difficult to continue to develop a price butcher. In addition, after years of development of screw compressors, screw machines of various brands on the market have been able to meet the needs of various application scenarios, but few companies can provide comprehensive application solutions for compressors. Through more than ten years of accumulation, A&S has been able to fully cover the market needs of various types of refrigerators, quick freezers, quick freezers, and medium and low temperature brine machines (load cooling) that require application of screw machines. In addition, through high temperature/low temperature , Single-stage/dual-stage, fixed frequency/frequency conversion products and application layout, established A&S's ability to provide comprehensive solutions for screw machine applications in the refrigeration and refrigeration market to meet the different needs of various projects, aiming to establish a win-win situation Cooperation model. At present, the replacement of refrigerants has also become the focus of attention of many screw companies. It is understood that carbon dioxide has occupied the mainstream of the European market, and refrigerants such as R22 and R404A have basically been eliminated. Therefore, in the future world refrigeration market, the development and reform of refrigerants is definitely the focus For enterprises, the trend brought about by the development of products and new technologies is inevitable. Energy conservation and environmental protection are the tide. Only by following the trend and the trend can they survive and develop better, and they will not be overwhelmed by the trend.
