Description
Screw air-cooled chiller(or heat) is the unit which in order to the
cooling medium (summer) and heat (winter ) water as the refrigerant
cold ( hot) water. It can join with fan coil units, air
conditioning box, air processor together make up half of
concentration and centralized the central air conditioning system;
Single cold- screw air-cooled chillers are widely used in various
fields of industrial refrigeration. 1. Compare with water chiller:
Compare with water chiller, it saves a huge Cooling water system.
And it also don`t need a Special air conditioning room. 2. Precise
stable water temperature: As used for industrial cooling, Low
temperature water which produced by air-cooled chiller could send
to the equipment and containers directly which need to be cooling.
3. Achieve annual refrigerate operation: In the industrial cooling
use aspect, Screw air-cooled chiller can use in above temperature
**0° C. Achieve annual refrigerate operation, In order to meet the
industrial cooling in the winter refrigeration requirements. 4.
Y-depressurization start mode: Screw air-cooled chiller(or heat)
use Y-depressurization start mode. 5. External air cooled oil
cooling device: In order to ensure good lubricating oil
lubrication, we use External air cooled oil cooling device to cool
down the temperarure, Reduce the consumption of cooling capacity
and Stable refrigeration system. 6. Perfect protection function:
Screw air-cooled chiller(or heat) have perfect protection function,
such as power wrong phase lack protection, System high-voltage
protection, System low voltage protection, Double antifreeze
protection, Compressor overload protection, The insufficient frozen
water cooling protection, Prevent frequent start protection,
Compressor built-in exhaust temperature and coil overheat
temperature protection and so on. 7. Well separated frozen oil and
refrigerants: In order to more fully the frozen oil and
refrigerants separation, Low temperature cold water chiller
external centrifugal efficient oil separator, it Can greatly reduce
in low temperature and stranded in the evaporator of frozen in oil.
8. Plus liquid spray technology: To further ensure compressor motor
not overheat, Screw air-cooled chiller(or heat) use plus liquid
spray technology, with low temperature cold media on the motor
cooling directly. 9. Automatic capacity adjustment: Screw
air-cooled chiller(or heat) according to the use of air
conditioning can automatically adjust load capacity. The standard
chiller capacity adjustment method using segmented or non-polar
uninstall way. *0. Green environmental protection: In order to
better protect the atmosphere, it Can producte green environmental
protection etc cooling medium refrigeration and air conditioning
equipment not only in adopts HFC**7C and HFC**4A, but also in
HCFC*2. *1. Balance run: Many of the chiller with compression,
microcomputer automatic memory will be per compressor operation
time, start the next time it will be activated running less time
compressor. *2. Remote control: Each chiller with remote control
function, the computer controller is equipped with RS**5
communication interface standards, open communication protocol, all
kinds of building monitoring system connected even remote different
ground monitoring. *3. Defrost: Accurate design aluminum pieces
from the maximum to reduce frost probability. *4. Waste heat &
secondary condensation: Rely on waste heat generated when the pump
cooling system to take domestic hot water, without additional
consumption of electricity, fuel; Almost zero cost; No pollution,
no need to add other devices, just access to water pipeline, direct
access to hot water. *5. Heat recovery chiller: In today 's
increasingly tense energy, waste heat use will have long-term
economic value, on this basis, the Division I developed a heat
recovery chiller can be full recovery of the original go condensing
waste heat released into the environment.
