Flooded Type Water Cooled Screw Chiller
Product Description
HWFS Flooded Type Water Cooled Screw Chiller
Flooded Water Cooled Chiller
We are manufacturer producing fan coil unit(fan coils)/air handling unit(ahu)/chiller
1)R22:368-3035kw R134a:363-1956kw
2)compressor:1/2/3 system:single/double/three Fushen compressor
3)evaporator: flooded type
4) separator :high efficiency separator for chiller
5)valve: electronic expansion valve
6)Siemens PLC for standard chiller unit
5)Chiller Compressor:
Double screw compressor( modified according to our design requirement
1Enlarge outlet size,reduce pressure drop,increase efficiency
2Modify capacity ratio different capacity ratio will be choosen according to different working conditioning
3enlarge rotor discharge outlet volume to increase the efficience
4high quality oil separator design
5check valve optimization design ,pressure drop less than0.02kg/c
Adopted in single compressor 30RT300RT,which is adopted in air conditioner, industry etc
6)
Chiller Flooded type evaporator
working theoryadopting big vessel boiling heat transfer theory, chilled tube is totally immersed in liquid refrigerant , the heat of the water inside the tube will be removed by the refrigerant through heat transfer to make it cool
1.Refrigerant is under boiling situation, water flow is in turbulenc which increase heat transfer efficiency. Superheat of outlet referigerant is around 2~3 , water flows into the cooper tube which is easily cleaned
2. Comparing with falling film exchanger , the constructure is more simple and the heat transfer efficiency is close. Comparing with dry type evaporator, the heat transer efficiency is high.
7)Chiller Oil Separator
Self developped high efficient oil separatorto ensure 3ppm return which has been adopted in Hefei General constitute and fushen test equipment
8)Chiller Electronice expansion valvesuction gas over heat control
Gas suction overheat control system is combined by electronic expansion valve, pressure sensor, temperature sensor and controller. P1 of the evaporator outlet is transferred to controller through pressure sensor and overheat is transferred to controller through temperature sensor,after controller handling the signal, it will output the instruction to stepping motor of the electronic expansion valve, then the valve will be opened to the position needed to guarantte the liquid requirment of the evaporator. No matter under any situation like standard ,varialbe working condition or full load,the high COP will be achieved
9)chiller Injection Pump
a)Compact design and simple constructure
b)Efficiency above90
c)Oil return effect achieved with less power consumption
d)No moving parts ensures reliable performance
e)Comparing with other factories, oil return is 15% higher
