What is a heat exchanger?
You are probably familiar with a car radiator that acts as a perfect example of a heat exchanger. It comes in contact with the air that cools the liquid in the radiator that in turn cools the engine for it to function optimally.
A heat exchanger is typically equipment that facilitates a transfer of thermal energy (heat) from one fluid medium to the other. The fluid could be gas or liquid. And the fluids could be two or more than two that the heat exchanger helps transfer heat amongst each other. Furthermore, the fluids do not have to be in direct contact for the heat to be transferred.
Ideally, heat is transferred through common heat transfer methods: conduction, convection, and radiation. Convection is the common method followed by conduction. Radiation is less common.
A heat exchanger is used in numerous applications in residential, commercial and industrial settings. It is common in industries, particularly chemical industries, where it is used to cool down or heat up process fluids for efficient operation. It basically takes heat from one fluid that does not need it to the other that need it.
Power plants and vehicle engines are commonplace where heat exchangers are used. Heat exchangers in many types depending on construction and fluid flow configurations. At Nearby EngineersNew York Engineers we specialize with all types to heat exchangers. We are experts MEP engineers in mechanical – HVAC engineering services and other akin engineering services such as plumbing, fire protection services, sprinkler engineering, and electrical engineering services. For this reason, designing the best heat exchangers is our strong point.
What are typical applications for a heat exchanger?
Heat exchangers are used in a plethora of commercial, residential and industrial applications. Residential buildings, for instance, can use heat exchangers to cool or warm the interior. They can therefore save enormous amounts of conventional electricity by relying on heat exchangers. Air conditioners and refrigerators are typical residential appliances that use heat exchangers albeit in the opposite way from the central heating systems. For instance, they extract heat from a compartment and discharge the fluid.
For your residential heat exchanger needs, Nearby EngineersNew York Engineers can customize the design to your desires. We are the top dogs in this industry and thus assure you top-notch quality in our residential heat exchangers. Experience has equipped us with unsurpassed skills in designing custom heat exchangers that optimize your living environment. In the same token, they save you electricity.
In industries, power plants and engines are common applications for heat exchangers. In the cars, for instance, we have exhaust gases dissipating heat extensively and so heat exchangers can be used to retrieve that heat although not all of it. It can be taken back through water as a fluid into the system. This in turn saves so much energy for your vehicle. That is how important heat exchanger is.
Our mechanical engineers can be able to install optimal heat exchangers where needed and make sure they run effectively. We can also maintain or repair malfunctioning tools, all thanks to our unparalleled HVAC mechanical engineering services.
Moreover about the engines, the fluid that is used to cool down the diesel engine in diesel vehicles can be passed through the heat exchangers to warm the interior of the vehicle instead of using excess electricity needlessly. You will not have to install additional heaters whereas the heat exchangers can retrieve the heat from the engines and convert the interior into a warm environment. Need a heat exchanger for your vehicle, contact Nearby EngineersNew York Engineers.
A car radiator, as we highlighted above, is a typical heat exchanger that most of you know. It has aluminum fins that are exposed to the air. When the fluid that cools the engine passes through the radiator, the air cools the liquid in the radiator and in turn this keeps the engine working optimally. The heat from the radiator can also be used to arm the interior of your vehicle. An expert MEP engineer should be able to optimize your vehicle’s heat transfer to curb energy costs.
Swimming pools also use heat exchangers to heat the water. The showers, too, use heat exchange concepts to keep them hot. Having the best design is therefore a need.
We don’t seem to include all the applications for heat exchangers. The bottom line is that there are plenty of them that use heat exchange concept. Whatever application that requires one, Nearby EngineersNew York Engineers can come to your rescue.
Types of Heat Exchangers to consider
There are notably plenty of heat exchangers on the market but they function the same albeit in a different way. The main concept is to transfer thermal energy from one fluid medium to the other. We still reiterate that whichever heat exchanger you have in mind, Nearby EngineersNew York Engineers can tailor that to your needs.
Among others, shell and tube, and plate/fin are the most common typical heat exchangers in the industry. Shell and tube is the most prevalent type followed by plate/fin. The name shell and tube should be self-explanatory that it refers to a shell with a tube inside. Basically, there is a set of metal tubes that contain fluid A while fluid B is contained in the shell with outlet and inlet.
The other fluid passes through the tubes that contain the other liquid to extract heat from it or to warm it. The fluids can move in parallel in the same direction where they are referred to as a parallel flow or co-current flow. They can move in a right angle to each other which is known as the cross flow, or they can move in the opposite direction which is termed as counter-flow or counter-current.
Plate/fin exchangers typically have metal plates or fins with a large surface area in which heat exchange takes place. Gaseous heat exchanges are often carried out using these types of exchangers.
Plate/fin and shell and tube are flow-based classifications of heat exchangers. There are also construction-based classifications: recuperative and regenerative exchangers.
Recuperative and Regenerative Heat exchangers
Recuperative and regenerative heat exchangers classify heat exchangers that Nearby EngineersNew York Engineers can design for you. In a recuperative heat exchanger, for instance, you have fluids flowing in separate paths. This is an ideal and common heat exchanger you can think of. The fluids do not mix but flow concurrently while the other draws heat from the other.
Recuperative heat exchangers are perfect examples of counter-flow exchangers. The main and basic definition of a heat exchanger dwells in these types of exchangers. Think of a heat exchanger in a heat-recovery ventilation system (HRV). It is a typical example of this type of thermal exchanger.
Regenerative heat exchangers, on the other hand, have fluids flowing in a single path alternatively. They embed a matrix that the hot fluid heats and passes. The cold fluid will pass thereafter to absorb the heat in that same path. These types of thermal exchangers are interchangeably referred to as capacitive heat exchangers.
Regenerative heat exchangers are commonly used for gas heat exchange operations mainly in energy-intensive industries such as power plants. These thermal exchangers are further categorized into static and dynamic, which are transient in operation.
Which heat exchanger is the best depends on your intended operation. If you are in the dark, Nearby EngineersNew York Engineers can come to your rescue with the choices. We can sit with you down to discuss the best solution for your case. Our engineers have been in this field for decades, and so they excel.
Features that add value when buying a heat exchanger
Given the highlights of the differences between heat exchangers above, you have a firm grasp of what you are looking for. However, it can even more complicated if we tell you that these exchangers come in different materials.
For swimming pools, plastic materials such as polymers engineered to resist erosion and corrosion can be used because temperatures are no extreme. But, for extremely hot fluids that could melt copper and polymers, you should consider other materials such as titanium and ceramic. Ceramic exchangers are great for temperatures that often exceed 1000 degrees Celsius.
In our designs, we want to understand your basic need of the heat exchanger and then choose the materials accordingly. The choice of proper materials limits the need for frequent maintenance because corrosion is less common. If you choose metallic exchangers for salty water, for example, they could be susceptible to corrosion and you may have to maintain them regularly. You should consider the purity of the fluids before selecting the heat exchangers. Some may be clogged by dirty fluids.
The size of the exchanger is also of paramount importance. Leave that to Nearby EngineersNew York Engineers to determine the correct size for your application. We are a dependable MEP mechanical partner in all your HVAC solutions.
Benefits of a heat exchanger
The benefits of a heat exchanger are enormous to include all in here. In line with the definition, heat exchangers help you transfer heat from one liquid to the other without actually combining the fluids. If you are working in a process industry, then heat exchangers are common and you will encounter them regularly. Nearby EngineersNew York Engineers have been designing and maintaining heat exchangers for multiple industries.
These exchangers are also common in commercial and residential buildings. Many heat systems are formed on this basis of heat exchanging. Think of a hot shower or HVAC systems installed. All these embrace the concept of thermal exchange.
Heat exchangers help reheat interior side of buildings, and in turn this saves more energy. Homeowners can cut costs significantly by employing the excellence of thermal exchangers. Our engineers can help you enjoy the perks of a heat exchanger in a residential or commercial building.
Installing Heat Exchangers
Installing heat exchangers is a complex process considering the configuration of these tools. One has to be careful and follow the instructions given. Because dealing with a heat exchanger requires a handy person with great technical skills, it is helpful to consider the services of a professional engineer in this regard.
Professional engineers design and install these heat exchangers. They also make sure that the devices run efficiently for their intended purpose. Not every task can be achieved through DIY. Thermal exchangers bear an example of that because not everyone can design and install them. Our engineers have mastered the art of designing and installing these devices.
Moreover, you need to consider maintenance hassles after installing the device. Maintenance ensures that the device runs smoothly at all times. With the best mechanical engineering services from Nearby EngineersNew York Engineers, you can rest assured that your maintenance schedules will be adhered to.
Most notably, heat exchangers are not all-in-one. You need someone who can decipher the proper materials versus the proper liquid fluids to be passed on or through these thermal exchangers. Incorrect matching of fluids and materials could lead to melting or corrosion. For instance, you may not choose polymer exchangers when dealing with extremely higher temperatures.
