Application· Providing low-temperature chilled water and
high-temperature hot water for air conditioning, and providing
various temperature glycol and brine for processing.· Widely used
in theater; hotels, shopping malls, hospitals, restaurants, office
buildings and other comfort air-conditioning systems; and the
cooling of electromechanical equipment the production of
instrumentation, textile, printing and other industrial
air-conditioning system; and also widely used in various industrial
production fields which need low-temperature.LS series provide
following optional functions: A.Heat recovery; B.Ice thermo
storage; C.Pressure of heat exchanger side: 1.6MPa and 2.0MPa;There
are many optional application conditions for both using side and
heat source side of RB series water(ground) source heat pump unit
this catalogue only lists technical parameters of water circulation
condition for model selection, and for detailed data of other
conditions, including the work ing condition of groundwater and
ultra-high temperature hot water(water outlet temperature higher
than 80,C), please contact with us.If YC/YS series glycol/brine
chiller are used under the circumstances of glycol/brine water
outlet temperature below -10ºC. economizer and oil cooler are
provided, please connect us if necessary.YC series units are only
suitable for glycol as secondary refrigerant The YS series units
can be used for secondary refrigerants such as calcium chloride and
sodium chloride.Technical AdvantageHigh performance semi-hermetic
dual-compressor screw unitIntroducing the modern fourth generation
of highly efficient rotor profile and special advanced KAPP rotor
milling lathe, ensuring higher processing precision and working
efficiency, improving the reliability of compressor
operation. Falling Film Evaporator with highly effective heat
transfer performanceThe heat transfer performance of falling film
evaporator is about 30% higher than flooded evaporator. Introducing
special designed distributor and processing technology, the liquid
refrigerant on the surface of heat exchange tube in the falling
film area can be evenly formed into the film, which has a great
advantage over boiling evaporation.Widely applicationThe chiller
can realize excellent performance not only in normal chilled water
application, but also in -20°C outlet chilled water and over 80°C
outlet hot water.Environmental friendly and energy savingAdopt
R134a which has no damage to the ozone layer. Refrigerant charging
quantity: 0.20~0.25kg/kW, 30-40% less than flooded compressor unit,
which can fully reduce the greenhouse effect.Among the alternative
refrigerant which can replace R22, working pressure of R134a is
about 50% lower than R404A and R507. The rotor leakage is reduced
because of low pressure difference of R134a compressor, and the
adiabatic efficiency and volumetric efficiency are improved
compared with R404A and R507. The theoretical cycle efficiency of
R134a is 12% higher than R404A and 6% higher than R507 on average,
which is an obvious advantage of energy-saving over R404A and R507.
Therefore, although the cost of R134a unit is higher than that of
R404A and R507 due to the low refrigerating capacity per unit of
swept volume, the BingShan falling film refrigerating units still
have a full range of products with R134a refrigerant.The energy
efficiency ratio of LS series falling film semi-hermetic screw
water chiller is above grade I or Hof national regulation GB19577.
Due to the small temperature difference between glycol/brine outlet
temperature and evaporating temperature, the energy efficiency
ratio of YC/YS series falling film glycol/brine unit is 12-15%
higher than dry glycol/brine unit and 5-10% higher than flooded
glycol/brine unit.Stable runninAdopt calculating opening control
algorithm to calculate the best opening of electronic expansion
valve according to the evaporating pressure, condensing pressure,
compressor energy class, etc., which keeps the liquid level stable
under various condition and ensures unit stable running.Separating
efficiency of oil separator is above 99.99%, which reduces the
reliance on oil return and the liquid refrigerant quantity that
come into compressor through ejector loop, avoids lowering the
viscosity of the lubricating oil because of excessive liquid
refrigerant which affects the service life of the :ompressor
bearings, and keep the compressor long-term stable
running.Convenient operation and high intelligenceConvenient
installation, just connect water pipe and power.Large colored touch
screen, free switch between manual control and automatic control.

intellectualization. Bingshan Group was founded in
1930(Investment by Panasonic & Chinese Goverment), there are 43
