HOW HVAC CAN BE LEARNED EASILY || BASIC 4 PORTION OF HVAC, NEED TO LEARN STEP BY STEP.Jabir Waqas

Jabir Waqas...Before getting into the steps required to become an HVAC technician, let’s take a minute to clarify what HVAC technicians do on a day-to-day basis. HVAC technicians perform a number of duties related to installing and repairing HVAC systems and equipment. Some of the specific responsibilities of an HVAC technician may include: Reading blueprints Use various tools (metal cutters, current meters, flow sensors, etc.) to repair HVAC systems Ensure that all components of the system (motors, pumps, fans, compressors, switches, thermostats, etc.) are working properly Connecting wires Testing electrical circuits Welding pipes Testing tubing and pipes for leak There are a lot of responsibilities associated with this career. But, if you enjoy fixing things and working with your hands, you’ll find it very rewarding. The heating, ventilation, air conditioning (HVAC) system works on three different sub-principles are Thermodynamics, fluid flow, and heat transfer. All three sub-principles are utilized at different steps of the whole process in the HVAC system. The Thermodynamics concept comes in effect to maintain the indoor air quality of the premises. The fluid flow mechanics comes in effect to maintain the temperature by passing the coolants in the coils of the air conditioning system. The third portion of the principle is the heat transfer segment of the main principle, where desired heat supply to the air is supplied in the room.
