By convention, q is shown as positive above the horizontal, when the circuit is inductive, and vice versa when capacitive see. But your air conditioner actually removes warm air and recirculates it as cool air. A universal motor is a singlephase series motor, which is able to run on either alternating current ac or direct current dc and the characteristics are similar for both ac and dc. How air conditioning works the essential ingredients in an air conditioning system are a fan to blow air around, a cold surface to cool and dehumidify the air, a warm surface and a source of water vapour. They think that an air conditioner functions by pumping cool air into their home. The basic principle of its operation is a simple conversion of 12v dc from a battery using integrated circuits and semiconductors at a. Ac drives are used to stepless speed control of squirrel cage induction motors mostly used in process plants due to its ruggedness and maintenance free long life. An air conditioner ac in a room or a car works by collecting hot air from a given space, processing it within itself with the help of a refrigerant and a bunch of coils and then releasing cool air into the same space where the hot air had originally been collected. From the relationships shown above among s, p, q, e, i, and. Ac drive control speed of ac motor by varying output voltage and frequency through sophisticated microprocessor controlled electronics device. This video describes the working principle of an air conditioner.
Heating loadheating load is the term used when additional heat is needed. Working principle of servo motor a servo motor is basically a dc motor in some spec ial cases it is ac motor along with some other special purpose components that make a dc motor a servo. The field windings of a series motors are connected in series with the armature windings. Main function of any airconditioner is to control the temperature and humidity of the air that is flowing into the room in which it is placed.
