Product Description

VFD Chiller Commerical Air Cooled Chiller Water Cooled Chiller

1. Eurostars water cooled commercial screw chiller main components
(1)Compressor
A highly reliable semi-hermetic design, features simple and robust construction by elimination of some components such as pistons, piston rings, valve plates, oil pumps which are found in reciprocating compressors. Without these components,screw compressors run with low noise level, minimized vibration, high reliability and durability
(2)Evaporator
Dry type shell and tube heat exchanger with cooper tubes optimizes the cooling and heating efficiency. Self-cleaning, high intensity, anti-shaking design and heat insulation covering material ensure shell and tube heat exchanger unstained, reliable, quiet, highly efficient.
(3)Condenser
Shell and tube type condenser with copper tubes optimizes efficient heat exchange between the chiller and cooling tower.
(4)Throttling Device
Adopt superior quality famous exterior balanced thermal expansion valve, which is high reliability and adjustability, can realize precise refrigerant and temperature control to ensure operating in precise and reliable status.
(5)Intellectualized Controller
Adopt micro computer touch screen control, can operate via centralized manage system; whole system can realize remote operation. The system can monitor the water temperature, capacity status while running. The water temperature can be controlled according to the water outlet temperature. Trouble shooting code may display on the touch screen automatically when the system is abnormal.
(6)Heat Recover (Optional)
Shell and tube type heat recover with copper tubes which can reclaim the heat should discharge outside to produce domestic hot water,save cost.



2. VFD for Eurostars Chiller
Generally, as chillers spend most of their operating time at only 40 to 70 percent load, installing a VFD on the chiller and/or auxiliary equipment in hot, humid climates can produce energy savings. It's important to note that when there are multiple chillers, savings may be less with the amount of decrease depending on the control strategy employed. VFDs aren't recommended for chillers that operate predominantly at full load because they
can decrease a little chiller full-load efficiency.

Application considerations:
The cost-effectiveness of a VFD for a water-cooled chiller is affected by several factors. Applications where VFDs are more likely to be cost-effective include those with the following characteristics:
(1)Low chiller load factors.
In applications where chillers spend a lot of time at low loads, VFDs will save the most energy and have the best chance of a quick payback.
(2)Long cooling hours.
Facilities that long more annual cooling hours are able to recoup the cost of cooling system improvements more quickly than those with limited or seasonal operating hours, such as a school.
(3)Presence of multiple chillers.
Many facilities have two or more chillers that can be staged as load changes. This can create an ideal opportunity to install one or more VFD chillers to improve capacity control. Using a VFD on only one chiller allows you to more fully load the non-VFD chillers and use the VFD chiller to make up the difference in needed capacity. Using a VFD on all chillers in a plant allows you to balance run hours on all the equipment while still reaping the energy-efficiency benefits of VFDs.
(4)Presence of a building automation system.
Because VFD chiller plants can be operated in different ways, a building automation system can help building staff determine whether operating practices are helping or hindering overall plant efficiency.
