Product Description
DIRECT COOLING CHILLER QLK190SMABXC FOR ALUMINUM ANODIZING

Product Performance:
Compressor
Direct Cooling Chiller for Aluminum Profile Anodizing

Flooded style: It adopts original installation import from Germany semi-closed twin-screw style compressor. The advanced 5:6 tooth design, screw style compressor rotor and yin yang rotor are in high precision CNC machining center one processing molding rotor, Two rotor space only for 0.01 mm. By oil film between sealing and transmission, brings excellent properties; The lever 4with Vi compensation energy regulation or non-polar energy-regulating, Meet different load conditions. Adjusting mode conversion only need to change compressor control procedures, don't need to modification compressor; This compressor with double shell, lever 3 oil separator; The avionics bearing with high precision makes the machine set less noisy, it also has the function to protect compressor automatic , and the service life reaches 100 thousand hours (over 30 years),In addition , when the cooling water inlet water temperature is low, the conventional water chiller is difficult to start, and the use of such compressor of Qingfeng flooded screw style chiller range of applications in low condensation temperature area gets greatly expanded. 

Evaporator
Direct Cooling Chiller for Aluminum Profile Anodizing
Flooded style: It adopts Qingfeng patent flooded evaporator and the latest big space mandatory nuclear states boiling design principle, with its built-in high efficient oil gathering device and compressor lever 3oil cent and system configuration of a whirlwind lever external oil cent safeguarded the system efficiency in heat and compressor good return oil. Adopting the CNC processing center and expands through 2.5Mpa pressure, free of wiped joint, so without any welding points. It makes evaporator with feature of small dimension, durable, easy operation, etc... Besides, flooded evaporator is convenient to clean, only to open the side cover. Evaporator adopts Qingfeng's patent external thread titanium, compared with ordinary heat exchange tube can improve the heat transfer area 2.5 times, improve the heat transfer efficiency. 

Condenser
Direct Cooling Chiller for Aluminum Profile Anodizing

Water cooling condenser: adopts shell and tube style water cooling condenser by using high efficiency outside screw tube from Japan. The needle wing tooth shape can effectively prick condensed liquid membrane, reaching to reduce liquid membrane thermal resistance that condensation refrigerant in the rapidly after condensation's effect. Condenser overall structure is processed in CNC machining center. The design more reasonable internal established independent super-cooling section, make high temperature refrigerants in the condenser internal have a fully cooling. Improve the heat transfer efficiency. It has features as small volume, durability and easy to clean. 
KINGFIT Energy-economizer: adopts efficient screw tube and rational design . It can carry on internal heat change between the under utilized refrigerant from the condenser and low temperature residual steam from the evaporator, making the refrigerant cool enough and the liquid in the steam vaporized. That will not only save energy above 8% but also protect the compressor from being stricken by the liquid and improve the service life of the compressor.
 
Electronic expansion valve
Electronic expansion valves are fully closed structure, by stepping motor driven from the full close to full open state while taking only a few seconds, reaction and movement fast speed, open close characteristics and speed are artificial setting. Electronic expansion valves available in 10%-100% range for accurate adjustment. And the adjusting range according to different characteristics of products set up. Electronic expansion valves can realize accurate refrigerant flow control meet the requirements of load under different operation conditions. Especially in flooded type system, can precisely control the liquid level of evaporator. Such the machine whatever in standard conditions, variable conditions, full load, variable load operation, it can keep the best COP value level. Now more and more systems with high COP. Accurate temperature control, broad operational range and require integration such as remote control, fault diagnosis and other new functions. Electronic control value's demand is imperative.
 
Protection device
Reliable water pump and freezer chiller chain of protection from inside of the system pressure control water pump drive and stopped. When the system pressure in normal working ,water pump in normal working . When the pressure is too low water pump will automatic stop. This design is to prevent evaporator leak refrigerant system into the tank liquid; Refrigerant abnormal protection, overload protection, overpressure and anti-phase protection, refrigerant anomaly protection, compressor over-temperature protection, over pressure refrigeration auto-discharge protection, oil pressure protection, hydropenia protection, leakage protection.
 
The refrigeration system has been embalmed, transmitter imported from Japan, welding and oxygen weld, no oxide layer.
 
When the ambient temperature is too low the machine will automatically adjust the condensing pressure.
 
KINGFIT Using the German advanced industrial-grade programmable logic controller PLC, large true color touch screen, imports of advanced low-voltage electrical control systems, can easily to achieve designer's energy-saving program. And also to achieve the chiller unprecedented energy savings.

Comparison of Program:
Our company professional production of oxidation-specific chiller, comparison between the world's most advanced indirect chillers has the following advantages:
 
1). Direct cooling chiller direct detection of bath temperature, so control tank temperature more accurate.
 
2). No need plate heat exchanger, no need chilled water pumps, water tanks.
 
3). Direct cooling chiller no need air agitation, the traditional indirct chiller have large temperature difference, and need through the air agitation to reduce the liquid temperature and oxidation goods temperature. Indirect cooling chiller: High investment costs and operating costs, oxidation products of poor stability.
 
4). Liquid temperature can be controlled in less than 2 ºC, the temperature difference between any two points on the tank does not exceed 0.5 degrees, This unique process significantly improve the uniformity of the oxide film and reduce the coloring material component than indirect cooling chiller. So to improve product quality, reduce scrap points.
 
5). Because of the blower or air compressor out of the temperature reach up to 70 ºC, increase the temperature of liquid, so increase the chiller running time. Blower or air compressor itself has electricity to run; Blower or air compressor easy to absorb the environment of dust and impurities. Air agitation process prayed into oxidation goods easy produce pit.
 
6). Saving power consumption at least 37% than indirect cooling chiller.
 
Specific comparison is as follows:
 Flooded style evaporatorDry style evaporator
Type of constructionShell and tube style Shell and tube style
Process mediumHeat transfer titanium alloy pipe internal flow is the tank solution, titanium evaporation tube outside between the barrel is the refrigerant. All of heat transfer tubes immersed in refrigerant.Heat transfer titanium alloy pipe internal flow is the refrigerant, titanium evaporation tube outside between the barrel flow is the liquid.
Exchange heat efficiencyAs the heat transfer tubes completely immersed in the refrigerant, so heat transfer is sufficient, Heat transfer temperature difference between the two liquids is very small.As the heat transfer tubes inner flow of refrigerant can not fully for heat exchange with liquid, in order to ensure that the evaporator has a superheat, so, in the dry evaporator,A part of heat transfer area is the refrigerant gas and liquid for heat exchange. So heat transfer efficiency is very low.
Evaporating temperature In the same outlet water conditions 18-22 ºC, the chiller of the evaporation temperature can be around 12 ºC.In the same outlet water conditions 18-22 ºC, the chiller of the evaporation temperature can be around 7 ºC.
Unit efficiencyBecause of the evaporation temperature is high, COP is generally above 5.5.Because of the evaporation temperature is low, COP is generally below 4.8.
