Mechanical engineering is an integral part of both HVACR (Heating, Ventilating, Air-Conditioning and Refrigeration) and plumbing. While both disciplines utilize the same science and engineering principles, their application diverges depending on the system under consideration. A prime example of this is the “wet” piping system that moves water through the piping network.
In the HVACR arena, the piping networks all operate in a “closed loop configuration.” In other words, the fluid (typically water with chemical additives) is contained within the confines of the piping and equipment network/system. This fluid, once internal to the system will not be drawn off from that system. Its sole purpose is to move thermal energy from one location to another.
