HVAC (Heating, Ventilation, and Air Conditioning) is the term of technology referring to indoor or self-propelled outdoor environmental ease. Air conditioners and refrigerators manufacturing industries can fall into the category of heating-cooling industry. HVAC is essential in the design of standards of big industries and their office buildings as healthy working conditions are needed there. These conditions are optimal temperatures and humidity which are controlled by heating and cooling devices and technologies like central air conditioning or industrial heat exchanger on a large-scale on the entire building.
The products created by HVAC industries like air conditioners, refrigerators, and work on the principle of heat exchange. The exchanging of heat plates happens through heat and cool exchangers that are the sub-devices utilized in refrigerators and air conditioners. Industrial heat exchangers are also known are thermal transfer exchangers.
Heat and Gas Exchanger
There are two kinds of HVAC exchangers which are utilized in heating and cooling industries, depending on the liquid utilized in the industrial heat exchanger or a gas. Normally, gas-type plate heat exchangers are utilized in households HVAC devices such as air conditioners and refrigerators. Also, it’s utilized in case of large volumes such as huge refrigerator systems for the cold storage stores of vegetables.
Newton’s law of cooling
The principle utilized in the air conditioning and refrigeration is based on newton’s law of cooling. For that, heat is moved from a body and its temperature is lowered down. In the process, coil exchangers are utilized. An industrial heat exchanger is a gift to mankind courtesy of the mechanical engineers. The volume and pressure regarding temperature prove this cooling theorem.
Water-to-air Industrial Heat Exchanger
Water-to-air industrial heat exchangers are also known as air coils or coils. The air coils constitute tubes of aluminum alloy. The coils act as an excellent exchanger of heat. Examples of the liquids utilized in HVAC coils are water steam, water glycols solutions, or any other coolant substance.
Cooling and Heating Coils
There are two types of coils one being cooling coil and the other heating coil. In the cooling one, the heat transfer process happens like air conditioning and refrigeration. On the other hand, in a heating coil, a boiler does the work of transferring the heat.
The principle by which industrial heat exchanger work is very technical. In different circumstances like in winter seasons, when the coils are exposed to the atmosphere, they can face problems such as freezing or exchanging liquid which can block the heat exchange tubes. Additionally, the tubes can get cracks since liquid expands when cooled. So, if the liquid in the tubes happens to cool down, it might damage the tubes.
