The product has applied for national patent.
This series of equipment adopts two different temperature zones of refrigerant two-stage mating operation, overcoming the single-stage compression refrigeration cycle pressure ratio is too large, as well as a single refrigerant two-stage compression of low temperature compressor suction temperature is low, low transmission coefficient and other shortcomings. It can provide low-temperature cold source from -30℃ to -145℃, and the maximum refrigeration capacity of a single unit can reach 910kW under the condition of evaporating temperature of -45℃, with a wide range of temperature and cold capacity, which is widely used in the fields of pharmacy process of pharmaceutical industry, low-temperature laboratory of automobile, electronics, aerospace industry, low-temperature recovery of oil and gas of petroleum and chemical industry as well as ultra-low-temperature processing and quick-freezing and refrigeration of food industry.
Among them, CWL series of refrigerant-carrying units can provide low-temperature refrigerant from -30℃ to -140℃; CUL series of compression condensing units can provide low-temperature refrigerant from -35℃ to -145℃.
FCWZ series water-cooled/evaporative cooled medium-low temperature falling film screw chiller unit
SCWZ series (evaporative cooling) single two-stage screw chiller is a new generation of refrigeration equipment based on decades of experience in the design of conventional low-temperature screw chiller, the application of high-efficiency screw compression technology, energy-saving economizer design technology, evaporative cooling technology, siphon oil cooling technology, multiple compressors in parallel, and other patented technologies and open.
ACW series normal temperature water-cooled inverter gas suspension centrifugal chiller is a new generation of chiller designed and developed by our company by synthesizing advanced technology at home and abroad. This series of products adopts dynamic pressure air suspension centrifugal compressor, which has the advantages of high efficiency, energy saving, low noise and environmental protection, etc. The unit is an oil-free system, which does not need to replace the lubricating oil, and almost realizes zero-maintenance operation, which can greatly reduce the user's operating costs and maintenance costs. According to the user's demand, this series of products can provide 4-16℃ carrier refrigerant, cold capacity range 75RT-800RT, covering a wide range, can be used in central air conditioning, rail transportation, medicine, chemical industry, electronics, food and other industries of the cold source host.
CO2 transcritical dual-engine two-stage unit is a green unit launched by our company in response to the national “dual-carbon policy”, with no Freon in the system, featuring high comprehensive energy efficiency, non-destruction of the ozone layer, and low global warming index, etc. The CO2 transcritical unit is a product developed by our company after years of research and development, and the compressor used in the system is also independently developed by our company. The compressor used in the system is also independently developed by our company. The evaporating temperature of the unit can reach -28~-50℃, which is suitable for cold storage and refrigerant-carrying system, and can meet the requirements of food, medicine, chemical industry, metallurgy and other industries.
ICW series water-cooled/evaporative-cooled industrial screw chiller units can provide -5～2℃ glycol water solution and 3～9℃ cold water, and can provide 8～15℃ cold water with large temperature difference according to the special requirements of users, which can be used as the mainframe of cold source for process in iron and steel, medicine, electronics, chemical industry, foodstuffs and other industries as well as mainframe of central air-conditioning and other kinds of places where there are requirements for chilled water.
The heat recovery type unit has added the polyheater technology on the basis of the standard type, which fully recovers the sensible heat in the compressor exhaust, so that the equipment not only meets the demand of cold source, but also provides high-quality hot water of 50~60℃ for living or heating.
Liquid supply temperature range -5℃~ 9℃
Cooling capacity 88.1kW~3622kW
In all kinds of environmental simulation test systems, in addition to the treatment of air, the treatment of the water system is also essential. It includes the treatment of water temperature, pressure, flow rate and water quality.
Land vehicles and other equipment, need to carry out all kinds of tests, including but not limited to: freezing test, high temperature test, low temperature test, temperature shock test, solar radiation test, rain test, humidity and heat test, low air pressure test, mold test, salt spray test, sand and dust test, vibration test, noise test, impact test and so on.
ice rink: Modern people pay more and more attention to the health of the body, and more and more diversified requirements for entertainment. Artificial ice skating rink easily realize the “north ice south”, in sports venues, shopping malls, schools, community clubs, parks and other places, supporting the appropriate area of the ice rink for figure skating, ice hockey, short-track speed skating, etc., to meet the people regardless of the season, regardless of the geographical limitations of the conditions of skating entertainment or sports training.
Our company can provide the planning and design of the whole ski resort, and the selection of a reasonable and feasible snow-making system is subject to strict scientific analysis and calculation. If the choice is not reasonable, it will cause the ski resort investment waste, and even lead to the ski resort can not operate normally. In addition, the ski resort construction design also includes the ski resort pipeline system design, reasonable design and calculation of snow-making amount, snow-making system design, snow-making system software system design; ski resort pumping station construction design; reservoir base data calculation, ski resort overall project calculation.
In ice rinks, increased outside temperatures can lead to the formation of vision-blurring fog, which can threaten the safety of skaters and prevent spectators from enjoying the game. This dehumidifier for ice rinks draws a large amount of moisture out of the air to ensure fog-free conditions are maintained throughout the year.
Ice truck is a skating rink ice finishing equipment that integrates clearing, collecting (ice and snow debris) and pouring in one, the electric ice pouring truck has the distinctive advantages of non-pollution, low noise, high efficiency, energy saving, environmental protection, etc., which can deal with the uneven ice surface caused by all kinds of reasons in a fast and high quality way.
