Classification of the Liquid cooling coil Or chiller (Indirect system)
The water cooling coils are further classified as the
. dry Expansion type chiller(shell and
tube type)
. Flooded Expansion type chiller(shell
and tube type)
. dry Expansion type chiller(shell and tube type)

The dry Expansion type of Evaporator Or chiller which is Cooled down Or chilled by the help of, water and maybe brine.
It construction, of the chiller The Refrigerant flows work The Tube side and the water to be chilled flows work the shell side. The shell is made of Cast iron and the tube Or coil is made of copper.The Evaporator or coil is a dry type since some of the tubes superheat the vapour to maintain a chilled water in the shell and the good heat transfer coefficient. The presence of baffles turns the flow around creating some turbulence thereby increasing the heat transfer coefficient.Widely spaced baffles are used when the flow rate is high or the liquid viscosity is high.
How does the dry Expansion type chiller(shell and tube type) work?
The function of the, dry Expansion type chiller First, tube Or coil is absorbing of heat to the normal water flows in the shell, then liquid refrigerant is Evaporated to Vapouriser ( inside the coil Or tube) to convert vapour refrigerant to the compressor then Cycling is Repeatedly agen and angen in all refrigeration parts equipped with refrigerating machine. The water cycling, flows through the shell in normal water. the cooled or chilled water in heat exchange for the normal water contact with chilled tube. This chilled water flows through the taken to a pump, which circulates it to the refrigeration load, other place in required.
Which type of metering device is used in the dry Expansion type chiller(shell and tube type) ?
Generally a thermostatic expansion valve is used. to controls the liquid refrigerant flows from the tube or coil and other metering device uses all so. the depends on capacity of the machine.
uses to the dry Expansion type chiller(shell and tube type)
Uses of the application for commercial or industrial refrigeration air conditioning system or plants. like a large refrigerating machine, large air conditioning plants, central air conditioning plants etc.
. Flooded Expansion type chiller(shell and tube type)

| Figure show - Flooded Expansion type chiller(shell and tube type) |
It as Flooded Expansion type chiller which is cooled or chilled by the help of water or brine.
If construction, of the chiller just like that a shell and tube type Condenser. the flooded type of the Evaporator or chiller The Refrigerant flows along the shell side at the water or fluid to be chilled flows along the tube side.The shell is made of cast iron and the tube or coils is made of copper.Shell and tube chillers are available in vertical design also. Compared to horizontal type, vertical type of the shell and tube type chillers require less floor area.
How does the Flooded Expansion type chiller(shell and tube type) work?
The function of the, flooded Expansion type chiller First, refrigerant is absorbing of heat to the normal water flows in the tube, then liquid refrigerant is Evaporated to Vapouriser ( inside the shell) to convert vapour refrigerant to the compressor then cycling is Repeatedly agen and angen in all Refrigeration parts equipped with Refrigerating machine. The water cycling flows through the tube side in normal water. the cooled or chilled water for heat exchange for the normal water contact with chilled refrigerant flows from the shell. This chilled water flows through the taken to a pump, which circulates it to the refrigeration load, other place in required.
Which type of the metering device used in the Flooded Expansion type chiller(shell and tube type) ?
In this type of chillers the flows of the liquid refrigerant is controls by the flooded valve or float valve out as a Expansion valve. which is maintains a constant level of the liquid refrigerant in the shell. The like of Expansion valve is used in the low side and high side.
uses to the Flooded Expansion type chiller(shell and tube type)
Uses of the application for commercial or industrial refrigeration air conditioning system or plants like a large refrigerating machine, large air conditioning plants, central air conditioning plants.
