What is heat exchanger and types of heat exchanger?
A heat exchanger is a device which transfers (or exchanges) heat from one fluid to another. There are many different names for heat exchangers because of their varied applications.
What are the types classifications of heat exchanger?
Heat exchangers are classified according to transfer processes into indirect- and direct- contact types. FIGURE 1.2 (a) Classification according to process function; (b) classification of condensers; (c) classification of liquid-to-vapor phase-change exchangers.
What is the best type of heat exchanger?
The parallel-flow heat exchanger is the most suitable one if the area is an important parameter where as the counter-flow heat exchanger for the maximum net gain. The maximum net gains for all heat exchanger types are given in Table 3.
What is heat exchanger in HVAC?
By its simplest definition, a heat exchanger transfers heat between two or more liquids. Each liquid is separated by a wall to prevent them from mixing. Sometimes, in an HVAC system, the heat exchange will occur between a gas and a liquid. They can be used for both heating and cooling.
Is boiler a heat exchanger?
In a boiler heat exchanger, heat is transferred from the hot gasses of a combustion process to water moving through the exchanger’s internal piping system. As a result, the water heats up as the gas cools down.
What is the function of heat exchanger?
Heat exchangers are used to transfer heat from one medium to another. These media may be a gas, liquid, or a combination of both. The media may be separated by a solid wall to prevent mixing or may be in direct contact.
What 3 types of material are heat exchangers made of?
While metals have a high resistance and are commonly used in constructing heat exchangers due to their high thermal conductivity, as in the case of copper, titanium, and stainless-steel heat exchangers, other materials, such as graphite, ceramics, composites, or plastics, may offer greater advantages depending on the
What are the two types of heat?
Two types of heat include sensible heat and latent heat. Sensible heat is the heat released or absorbed when there is no phase change. This release or absorption does change the temperature of a substance.
What are the main heat exchangers?

What is fouling factor?
The fouling factor represents the theoretical resistance to heat flow due to the buildup of a fouling layer on the tube surfaces of the heat exchanger. In practice, fouling factors are often overstated by the end user in an attempt to minimize the frequency of cleaning.
Which material is used in heat exchanger?
Generally, the two most commonly selected materials for heat exchangers are aluminium and copper. Both metals have the optimum thermal properties and corrosion resistance to make them ideal choices, with most of the differences being application-specific.
Where is a heat exchanger located?
A heat exchanger is a metal device that’s located inside your furnace. It has two primary purposes. First, it provides heat to your home’s air while your furnace is operating.
Do heat exchangers use gas?
The heat exchanger uses the combustion gases to warm the air, which is then distributed around the home. Exhaust gases from the combustion process are released through the flue to the outside of the home.
Is condenser a heat exchanger?
In systems involving heat transfer, a condenser is a heat exchanger used to condense a gaseous substance into a liquid state through cooling. In so doing, the latent heat is released by the substance and transferred to the surrounding environment.
Is evaporator a heat exchanger?
For example, the condensation of gas, called “condenser”. Of course, the liquid evaporates, called the evaporator. However, they still belong to the category of heat exchangers.
What are the 4 types of heat transfer?
Various heat transfer mechanisms exist, including convection, conduction, thermal radiation, and evaporative cooling.
What is heat exchanger efficiency?
The heat exchanger efficiency is defined as the ratio of the heat transferred in the actual heat exchanger to the heat that would be transferred in the ideal heat exchanger. The concept of heat exchanger efficiency provides a new way for the design and analysis of heat exchangers and heat exchanger networks.
How do you calculate heat exchanger?
The main basic Heat Exchanger equation is:
- Q = U x A x ΔTm = The log mean temperature difference ΔTm is:
- ΔTm = (T1 – t2) – (T2 – t1)
- = °F. Where:
- T1 = Inlet tube side fluid temperature; t2 = Outlet shell side fluid temperature;
- ln (T1 – t2) (T2 – t1)
