Maximum Efficiency with Scroll compressor
Most advanced and well known scroll compressor with better liquid handling , improved performance, and less moving parts which increases the system operating efficiency and reliability. Multiple scroll compressor used, so the system energy efficiency has been greatly improved at part load performance.
In a scroll compressor refrigerant is compressed by two offset spiral disks that are nested together. The upper disk is stationary while the lower disk moves in orbital fashion. The orbiting action of the lower disk inside the stationary disk creates sealed spaces of varying volume. Refrigerant is sucked in through inlet ports at the perimeter of the scroll. A quantity of refrigerant becomes trapped in one of the sealed spaces. As the disk orbits the enclosed space containing the refrigerant is transferred toward the centre of the disk and its volume decreases. As the volume decreases, the refrigerant is compressed. The compressed refrigerant is discharged through a port at the centre of the upper disk. Scroll compressors are quiet, smooth-operating units with the highest efficiency ratio of all compressor types. They are commonly used in automobile air conditioning systems and commercial chillers.
Evaporator
Dry type evaporator scroll chiller is equipped with high efficiency shell and tube evaporator that are constructed by seamless steel tube with anti-corrosive treatment. The evaporator is a direct expansion type with refrigerant inside the copper tubes and water on the outside. The copper tubes are roll expanded into carbon steel tube plates. Constructed with seamless integrally finned copper, the water pipe system makes the evaporator attain optimal heat exchange efficient. Two return passages of water flow and the straight water pipe is easy for cleaning and maintenance. Both end covers are made of iron and attached with protection valve and snuffle valve. Also they are removable, which makes it available for altering water piping arrangement.
High efficient tube:
According to the heat exchange efficiency of refrigerant side and water side, calculate the numbers of tube and get the heat exchange efficiency;
Use inside and outside strengthened heat exchanger tube to make the heat exchange efficiency reach to the best Definite the best liquid distribution type based on two phase flow principle. The refrigerant enters the evaporator evenly to ensure each heat exchange tube can transfer heat well
WATER COOLED CONDENSER
Shell and tube heat exchanger with external still sheet shell and internal cooper pipe bundled. The cooper pipe are expanded in to terminal plates at the end. The head plates can be removed for maintenance procedures. The water connection can be used for operation with cooling tower.
It can be designed to suitable for different fouling factors. There is a reserved 15% heat exchange capacity design which can make the condenser provide enough capacity even the cooling water temperature re aches 32℃ or there is fouling inside the water system.
V Type AIR COOLED Condenser:
Condenser adopts the Copper tube & hydrophilic aluminum fin(blue fin )coil type structure, the appearance is V type,
this design increase the heat exchange area, reduce the temp. difference thus increase the heat exchange efficiency 0%.
