Summary Of Components Found On A Water Chiller

Air cooled condenser –

a type of condenser where refrigerant flows through the tubes and rejects heat into a flow of ambient air, most chiller hire units are fitted with air cooled condensers

Capillary Tube –

A type of expansion devise typically fitted on small capacity hire chillers, it comprises a long tube which reduces the pressure of the refrigerant.

Centrifugal Fan –

A type of fan fitted to an air cooled chiller allowing the fitting of ductwork onto the hot side of an air cooled condenser.

The fan is designed to work against a static pressure.

Compressor –

The main component in a chiller system, the compressor is used to increase the pressure & temperature of the refrigerant vapour.

Condenser –

The part of a chiller system where the refrigerant vapour is converted to liquid as it rejects heat.

Cooling Tower –

Used for process cooling applications & water cooled chiller condenser cooling

Distributor –

A devise used to supply uniform gas supply through a submerged coil in tank chiller evaporator

Enthalpy –

The property of a refrigerant indicating its heat content per Kg of refrigerant

Evaporator –

The part of the chiller system where cool liquid refrigerant absorbs heat from the chilled water circuit

Expansion valve –

A devise used to maintain the pressure difference between the high pressure & low pressure sides of the chiller system

Fill –

The heat transfer surface inside a cooling tower

Flash –

The process of liquid refrigerant being vaporised by a sudden reduction is pressure when entering the low pressure side of the chiller system

Hot Gas Muffler –

A device installed at the discharge side of the chiller compressor to reduce noise and vibration in reciprocating compressors

Liquid Line Filter Drier –

A devise installed in the liquid line to remove moisture and foreign matter, designed to protect the chillers compressor.

Pump Down Cycle –

A control sequence used in a chiller system to pump the refrigerant from the low pressure side of the system to the high pressure side.

Shell & Tube Evaporator –

A type of evaporator where refrigerant flows through the tubes & chilled water fills the surrounding shell

Shut Off Valve –

Used to isolate on part of the chiller system from the rest

Sub-Cooler –

The lower portion of the chillers condenser that further cools the saturated liquid refrigerant

Suction Header –

A section of pipe within the chiller system used to collect the refrigerant vapour when it leaves the tubes of a submerged coil evaporator

Suction Line Filter –

A devise installed into the chillers suction line to remove foreign matter from the refrigeration system

Superheat –

The amount of heat added to the chillers refrigerant vapour after it has vaporised within the evaporator.

Water Cooled Condenser –

A type of chiller condenser coil which water is used to remove heat from the refrigerant, this is normally a shell & tube type design.

Heat preservation for pipelines of chilled water

Action on heat preservation must be taken not only to prevent heat loss, but also to prevent dew on pipelines.

e.g. using metal pipeline (length 25m, surface area 25m2), chilled water -- 100C, circumstance temperature 300C, heat loss may goes up to 750Kcal/h, i.e. 10% of nominal chilling capacity of 3Hp water chiller.
