250 Kw 100 Hp Industrial Air Cooled Screw Water Chiller
Main Features
-
Packaged air cooled screw water chiller machine adopt the semi-hermetic screw compressor(like Habell,Bitzer), and operate credibility, high efficiency, easy to maintain, exact volume control, a wide range of application. The system adopts the latest asymmetric rotor profile. Build-in pressure drop lubricant to system with low vibrations, sound emissionshigh sealing performance.
-
Packaged air cooled screw water chiller machine 's human machine interface configures a full touch screen, which enables automatic control and accurate monitoring. The advantages of unit: water-proof,dust-proof, corrosion resistant, long life. Step or stepless capacity control, the unit ensure that it bring into the most energy-saving effective in any load conditions.
-
Packaged air cooled screw water chiller machine due to use heat copper tube and high efficiency compressor with high effective thermal expansion current-saving device, the unit will operate in stability, longer and effectively.
-
Packaged air cooled screw water chiller machine adopts a reliable safety protection device: to prevent compressor starting frequently, over-current protection, overheat of motor protection, prevent freezing, sight glass in liquid, oil heating protection, phase protection, HV/LV protection, discharge high-temperature protection, safety value, soluble clock, water shut-off protection, and so on.

FAQ:
1.How does a chiller system work?Chiller has two circulation,one is process water circulation,the other is refrigerant gas circulation.Heat picked up from the process.Heat transfers to refrigerant circulation.Heat is remove to air or water.
2.How to calculate cooling capacity for chillers
Cooling Capacity(kw)= Flow Rate(m3/h)*Temp Change(T1-t2)/0.86
Heat Load= C(specific heat)* M(quality output per hour )*Temp Change(T1-T2)
3.Types of chiller system?
Air Cooled Chiller and Water Cooled Chiller.Water cooled chiller needs a separated cooling tower and has a higher efficiency,but less easier than air cooled.
4.Cooling capacity unit conversion?
1 kcal／h ＝ 1.163W,1 W ＝ 0.8598 kcal／h；
1 Btu／h ＝ 0.2931W,1 W ＝ 3.412 Btu／h；
1 USRT ＝ 3.517 kW,1 kW ＝ 0.28434 USRT；
1 kcal／h ＝ 3.968 Btu／h,1 Btu／h ＝ 0.252 kcal／h；
1 USRT ＝ 3024 kcal／h,10000 kcal／h ＝ 3.3069 USRT；
5.This chiller could do heat recovery?
Yes,please kindly send us the temp and water volume per hour.
6.Chiller maintenance?
Step 1: Keep Tubes Clean
Step 2: Ensure a Leak-free Unit
Step 3: Sustain Proper Water Treatment(prevent scale, corrosion)
Step 4: Analyze Oil and Refrigerant
