Causes and harms of non-condensable gas produced by refrigeration system Frequently asked questions about refrigeration compressors Do you know these? How to solve the problems encountered during the operation of 120KW cold air-cooled compressor Leading refrigeration compressor manufacturer company operating worldwide One of the directions of scroll compressor's attack deep dive into the low-temperature marketrefrigeration compressorIndustry prospects
In Panasonic's view, in the field of air conditioning, after the high-power rotor machine, relying on the cost advantage, quickly seize the market of 3-7HP scroll machine; For use in convenience stores, scroll machines are popular with customers for their low vibration and high efficiency. Panasonic will continue to launch new products, actively respond to market changes, provide customers with more choices, and provide more business opportunities for enterprises.
Panasonic still has confidence in the application of scroll compressors at low temperatures. The minimum evaporation temperature of Panasonic low-temperature scroll machines: R404A refrigerant can reach -45 ℃, R22 refrigerant can reach -40 ℃. Compared with the high temperature engine, Panasonic's special low-temperature scroll machine firstly improves the compressor's exhaust structure, scroll profile, motor efficiency and other aspects; at the same time, it uses liquid injection cooling technology to ensure the compressor's low exhaust temperature; And protect the compressor by two ways to the compressor discharge temperature and the motor coil temperature. Therefore, even the harsh conditions of very low evaporation temperature can operate stably.
Panasonic believes that low-temperature scroll compressors want to break through, should be DC frequency conversion, high horsepower, high COP, low noise, and more energy-saving. The application scenarios should include ultra-low temperature wind cabinets for commercial and supermarket use, refrigerated trucks, refrigerated containers, small low temperature Brine unit and cold storage, etc. On the other hand, in terms of natural refrigerants and environmentally friendly refrigerants, CO2 products have been vigorously promoted in China, and have been widely used in European and Japanese markets.
Danfoss also analyzed that at present, the market share of semi-hermetic piston compressors is decreasing year by year. The replacement of semi-hermetic piston compressors is mainly two types of products, one is a semi-closed screw, and the other is a scroll compressor. There are already many Crew users moved from pistons to vortex applications. At present, the rotor compressor still has some limitations. The first is mainly low power 3P and below, and the second product maturity and technology need to be improved. Scroll compressors are at a mature stage, and new technologies and new products are constantly emerging. For example, the variable-frequency scroll compressor has gradually formed a climate in the past two years. Fixed-frequency compressors are more abundant and perfect. Parallel or fixed-frequency scroll + variable-frequency scroll systems can be used. These have great room for development.
In fact, from the user's perspective, they are related in terms of demand. For example, the cooling capacity required by the convenience store is about 2P-8P, and the small supermarket and fresh store is about 2p-10p. The rotor can only provide a small amount of refrigeration, and it needs more technical development to meet the market's needs. demand. From an application point of view, more and more customers are paying attention to convenience stores, satellite warehouses, etc. These customer equipment are mostly used in residential areas, which have high noise requirements for the equipment and it is relatively difficult to control the noise of the rotor. Therefore, whether it is from the hot spot of market development, or in terms of technological maturity and scope of application, Danfoss believes that the vortex has a very promising prospect and will continue to dig deeper into the scope of application and expand the product line.
In addition to layout frequency conversion, the application of new refrigerants is also the development trend of scroll compressor companies. Emerson predicts that in the next 3 to 5 years, the R32 scroll compressor market will usher in greater growth, so Emerson has already realized the full range of R32 products in advance. An industry source said that Guangzhou Hitachi's R32 products have also achieved a full series, and are currently mainly exported to the European market.refrigeration compressor Industry prospects
