Water to Water Heat Exchanger Water to water heat exchangers transfer heat energy from one liquid to another without bringing the two liquids into direct contact in a similar method as air to air heat exchangers. Typically with a shell and tube or spiral design, water to water heat exchangers work through forcing hot fluids to flow through heat-conducting tubes over which liquid coolants flow. The heat is absorbed by the coolants and thus removed from the water, dropping its core temperature and allowing it to move on in its process.

What is a Water to Water Heat Exchanger?

Water to water heat exchangers are responsible for exchanging heat between wastewater and freshwater. The heat transfer process between the liquids does not involve direct contact or mixing of the two.

Materials Used in Water to Water Heat Exchangers

Usually, heat exchangers are made up of metals. However, they can also be made of plastics, ceramics, or composites. Ceramics are used for high-temperature applications because such high temperatures would melt metals such as steel, copper, and iron.

Abrasive and corrosive fluids make use of heat exchangers made up of ceramics. On the other hand, plastics are generally very cheap and lighter than metals. Plastics resist corrosion, and their thermal conductivity is good. However, mechanically, plastics are weak and unfit for high-temperature applications. Their main use is found in water-based applications like swimming pools and showers.

How Water to Water Heat Exchangers Function

Water to water heat exchangers function by allowing fresh water to flow and circulate around the hotter wastewater that flows out. During this process, there is a heat energy transfer from the wastewater to the freshwater through the inside walls.

How Heat Exchangers Work

The freshwater is heated to high temperatures of over 100 °F (37.7 °C). On exiting the unit, the wastewater is cooled. The principle of the water to water heat exchanger is that there is heat transfer without the transfer of the fluid that carries the heat.

Types of Water to Water Heat Exchanger

There are various types of water to water heat exchangers. The shell and tube heat exchangers and the plate heat exchangers are the two most common types.

Shell and Tube Heat Exchangers

Shell and tube heat exchangers are made of a single tube or parallel tubes known as a tube bundle, enclosed in a sealed cylindrical pressure vessel. One fluid flows through the smaller tube while the other flows around the outside and within the sealed shell.

Shell and Tube Heat Exchange

Other design characteristics include single or two-phase heat transfer, concurrent flow, finned tubes, crossflow arrangements, counter-current flow, and single, two, or multiple pass configurations.

Plate Heat Exchangers

Plate heat exchangers are composed of many corrugated, thin plates bundled together. Each pair of plates makes a channel through which a fluid can flow. The process is undertaken when the pairs are attached and stacked via welding, bolting, or brazing.

This allows for a second passage to be formed between the pairs through which the other fluid can flow. The plate design has different variations like pillow plate heat exchangers or plate fin heat exchangers.

Plate fin heat exchangers employ spacers or fins between the plates and cater to many flow configurations and more than two streams of fluid to pass through the device. In addition, pillow plate exchangers make use of pressure on the plates to increase the efficiency of heat transfer across the plate surface.

Other types of plate heat exchangers are spiral plate heat exchangers, plate and frame heat exchangers, and plate and shell heat exchangers.

Applications of Water to Water Heat Exchangers

Water to water heat exchangers have various purposes in the commercial and industrial sectors. Their uses are radiant floor heating, solar heating, and domestic hot water heating. Water to water heat exchangers are used with refrigerants in heating, ventilation, air conditioning, and refrigeration applications. They are also used in breweries for wort chilling. In addition, shell and tube heat exchangers are used in marine applications such as heated swimming pools.

Water to water heat exchangers can save on water heating by about 80%. For example, energy-efficient showers use heat exchangers in the wastewater outlet. The water dripping down the plug goes through the copper coils of a heat exchanger. In addition, industrial and commercial facilities use water to water heat exchangers to cool their wastewater for city sewers. This will allow them to cool the waste without adding cold water to the waste.
