What type of heat exchanger is an evaporator?

Both shell-and- tube and plate-and-frame heat exchangers can be used as evaporators in a process cooling system. The types of heat exchangers used as evaporators include dry expansion, flooded shell-and-tube and thermosyphon (flooded tube) evaporators as well as plate-and-frame heat exchangers.

Is evaporator and condenser are heat exchanger?

Condensers and evaporators are basically heat exchangers in which the refrigerant undergoes a phase change. In evaporators, the liquid refrigerant evaporates by extracting heat from an external fluid (low temperature heat source).

What is the difference between a heat exchanger and a condenser?

Condenser and Heat Exchangers: A condenser is an apparatus intended to condense vapors to a liquid state from their gaseous state. A heat exchanger works to conduct heat from a substance of higher temperature to a substance of lower temperature without phase changes.

What is the difference between a heat exchanger and a chiller?

The major difference between a heat exchanger and a chiller is in the design. While chiller systems possess refrigeration units that cool their circulating chiller fluid, a heat exchanger lacks a refrigeration unit and achieves temperature regulation by direct fluid heat transfer.

Why is an evaporator a heat exchanger?

HEAT EXCHANGERS COMMONLY USED FOR EVAPORATORS AND CONDENSERS. In the evaporator, refrigerant changes from the liquid to the gaseous state while removing heat from the cooling fluid. In the condenser, refrigerant changes from the vapor to the liquid state giving heat to the heat rejection fluid.

What is Evaporator in chiller?

Chiller Evaporators. The evaporator collects all the unwanted heat from the building. This is where the chilled water is produced. It collects the heat, removes it and send the water back out around the building to collect more heat.

Do heat exchangers use heat or cool?

A heat exchanger is a device that transfers thermal energy from one medium to another. Heat exchangers not only assist in the cooling and heating of homes and buildings, but also help machines and engines work more efficiently.

What is function of evaporator?

An evaporator is a device used in a process to turn the liquid form of a chemical substance, such as water, into its gaseous form – vapor. The liquid is evaporated, or vaporized, into a gas form of the targeted substance in that process.
