Difference between Heat Exchanger & Chiller

Difference between Heat Exchanger & Chiller

What is Heat Exchanger?

A device for transferring thermal energy by natural convection from one medium with high kinetic energy to another with low kinetic energy without physical contact between them.

Heat exchanger heats cool fluids by transferring heat between fluid streams flowing at different temperatures.

A heat exchanger is a device that transfers the energy provided by one stream of fluid to another stream. The fluid flowing through the exchanger can be a liquid or a gas, and most typically they deal with various types of cooling or heating applications. 

A heat exchanger is a device used to transfer heat between two or more fluids. Heat exchangers are typically found in cooling systems, such as air conditioners and refrigerators, and in heating systems, such as water heaters and furnaces.

A heat exchanger is an enclosed device where one of the fluids inside of it must be at a temperature that's higher than the other. The warm fluid will "take" some of the cool fluid's heat, which will warm up in turn. A similar process takes place in reverse in a chiller to decrease its temperatures.

What is Chiller?

A Chiller is a device where cold water is pumped at high pressure against an outside surface so cold coolant reaches its desired temperature.

Chiller removes heat to make substances cooler. Contrast with methods for adding heat (heating, solar reflector). Can use gas, water, or electricity as an energy source. chiller has two stages, one zone where cold vapor is subcooled and another zone where the subcooled vapor condenses into liquids. Then it moves to another zone inside the chiller that utilizes refrigeration to extract the latent heat outside of the chiller coils. With the refrigerant then liquefying again in its final zone to provide cooling services.

Chillers are used to lower the temperature of liquids, typically cooling them below room or ambient temperatures, whereas exchangers can both increase and decrease temperatures depending on which direction they're operating. 

A chiller is a type of heat exchanger that is used specifically for cooling purposes. A chiller works by transferring heat from a fluid that is being cooled (the "coolant") to another fluid that is capable of absorbing more heat (the "condenser"). This process causes the coolant to become colder, which then can be used to cool down spaces or objects.

The difference between a heat exchanger and a chiller is the way the gases are cooled, The detailed explanation is as follows:

A Heat exchanger is a device that transfers heat from one medium to another by means of direct contact, while a chiller is used to remove heat from the system.

A Chiller blows liquid refrigerant through long coils of metal pipes to absorb heat. 

A Heat Exchanger uses liquid refrigerant with another liquid so it doesn't need long pipes; the two liquids simply pass past each other, one absorbing the other's heat. The fluids cool themselves by exchanging their temperatures, which is why they're called "thermodynamic radiators." 

A Heat Exchanger uses direct contact with no moving parts and uses water or steam to transfer heat. 

A Chiller uses circulating fluid to transfer heat without any contact with the system.

A Chiller is a device that uses refrigeration to produce cold air. It is commonly used in air conditioning systems to cool buildings or rooms.

A Heat Exchanger is a device that exchanges heat between two different systems by using a liquid medium, for example, a coolant and the system being cooled.

A Chiller is an air-cooled or water-cooled machine that uses refrigeration to cool its surroundings and produces cold air or water.

A Heat Exchanger can be used to transfer either liquid or gas, while a chiller transfers liquid. 

It is easier to use heat exchangers than chillers because they are simpler and require less energy for operation.
