How To Understand the Efficiency of a Heat Exchanger

A heat exchanger plays a vital role in certain equipment like air conditioning systems, chemical refrigeration, petroleum plants, petrochemical plants, space heating, treatment of water systems and many more. A heat exchanger is an apparatus designed for effective heat transfer from one area to another. There are different types of heat exchangers, and these are the adiabatic wheel heat exchanger, dynamic scraped surface heat exchanger, fluid heat exchanger, plate fin heat exchanger, phase-change heat exchanger, plate heat exchanger, regenerative heat exchanger, shell and tube heat exchanger, waste heat recovery units and direct contact and spiral heat. The most common type of heat exchanger is the one that you can find in your automobile, the radiator. The car radiator helps to transmit heat from the hot coolant that streams through it to the air propelled by the fan. The majority of cars today use aluminum radiators.

Spiral heat exchangers have a self-cleaning system that has the capacity to manage fouling without difficulty. It is very important to calculate the real performance of your heat exchanger. You can do this by testing its efficiency using the proper heat exchanger equation.

Understanding the efficiency of a heat exchanger is very important, most especially if you are going to use them in your business or personal equipment. The equation differs from one type to another. You need to do a lot of math in order to get the answer. Your heat exchanger’s performance may possibly be categorized in accordance with the flow management. In a heat exchanger with a counter flow arrangement, the liquids go through the exchanger from opposing ends; while in a heat exchanger with parallel flow management, the two liquids go through the exchanger from the same end. According to the studies, the counter flow arrangement is the more efficient, as compared to the parallel flow arrangement.

Recognizing the efficiency/effectiveness of a heat exchanger is indeed difficult. You can do your calculations by hand, but you need to do a lot of computations/tests before you can come up with the accurate answer. The formulas can be found in engineering books and even online websites. You can hire an engineer, particularly a systems engineer who is well informed about heat exchangers. He will help you work out the heat exchanger controls that you need. Definitely, the service fee is expensive, but it will indubitably help you and your business.

Heat exchangers are extremely important, particularly to industry. The kind and size of heat exchangers can be modified to go well with industrial procedures relying on the kind of liquid, concentration, pressure and temperatures among other factors. Heat exchangers help to save a lot of money and energy. In heat energy, it helps to get back the energy drained and use it again by warming a different flow in the procedure.
