HVAC Heat Exchangers. In this video we'll be answering what is a heat exchanger, how does a heat exchanger work and then using 3D models we'll review real world applications to help you learn HVAC heat exchangers and building services.. We'll look at plate heat exchangers, shell and tube heat exchangers, duct heaters, furnace evaporators, cooling coils, trench heaters, rotary heat exchangers and many many more.

Hey man, really interesting video! Thanks for sharing! I wonder if you have done or would do a video on the relative efficiency of each of these systems and also a video where you compare heat transfer fluids, like air, water and the different refrigerants. Also if you know about combined cycle electricity generation at low temperatures (home scale with refrigerants?) I would love to hear more about that too! I live off grid in Canada so I am always searching for ways to make my homestead more efficient and effective. If I could make electricity from my woodstove in winter, with refrigerants producing power and hot water (when my solar panels are not putting out much power) that would be amazing!

@@Pasunreve212 I wouldn't say that . I mean it does push out air but the heat exchanger inside it can be heating or cooling or can have one of each . And the heat exchanger most often is just one of many in a system . The ahu has a method of preheating air coming from outside . One method is using the exhausting air and mixing it to create desired setpoint . A second method is a heat recovery that indirectly uses exhaust air to preheat incoming outside air .

You are using the term convection in the wrong application. All of this is conduction. When the hot surface comes into physical contact with the colder air, there is energy transferred by conduction. When two items of physical matter meet with a temperature gradient, that is conduction. Convection requires physical movement of a fluid. But even with that physical movement, you can not have convection until you conduct the energy first. So all convective heating is just conduction through a fluid. But when that fluid moves, it heats up the fluid next to it, again by conduction. Fluid is matter, so when matter comes into conduct with other matter, that is conduction. To make this clearer, it is like saying that there are three types of energy sources: Fossil fuels, nuclear, and electric. One is not like the others. Convection does not transfer energy. Convection is what you can call conduction if at least one of the conduction surfaces is a fluid.

@Weirdomanification 2 жыл бұрын

@jimcervantes5659 5 жыл бұрын

I don't recognize your use of the word "convection.". Convection involves the bulk transfer of heat driven by gravity, where temperature differences in a fluid (gas or liquid) correspond to density differences which under the influence of gravity lead to pressure gradients that drive convection currents. Hence hot air rising and cool air sinking, for example. When you drive air through a coil to transfer heat it is predominantly conduction. Maybe HVAC has its own use of the word. Or maybe I'm all wet.

They can be a preheat coil or a final heating coil depending on where they are located in a system . Just think of them as something that adds heat to air moving through a duct.
