Difference between refrigerator and air conditioner.

Difference between refrigerator and Air conditioner.

In short term

Refrigerator - A device which is used for cooling only.




Air conditioner - A device which is used for to make a comfort condition.

Refrigerator and air conditioner both are working on same principle.
Vapour compression cycle
Vapour absorption cycle.
In air conditioner 4 elements or controlled
1. Temperature
2. Humidity
3. Cleanness of air
4. Air distribution

Function of reactor in inverter AC

Image
 There are two types of reactor. 1. AC Reactor -AC Reactor is basically an inductor used in series of AC supply. -Transients and harmonics are generated from inverter due to high current switching in Inverter Circuit. Also Inverter Drive circuit is sensitive to external surges and spikes Function of ac reactor 1 Reduce Harmonics 2 Restrict Transients 3 Suppress external surges 4 Improve input Power factor -AC Reactors are generally required where very high VA Inverter drive is used. -Also if our Drive circuit needs to comply to some Statuatory standards then AC reactors helps in achieving required specifications DC reactor -DC Reactor is also basically an inductor connected in the DC bus between the Rectifier bridge and the capacitor bank. Function of DC REACTOR 1. Reduce Harmonics 2. Restrict Transients 3. Improve Input Powerfactor -DC reactors donot protect Rectifiers from possible voltage transients in mains Advantage of DC Reactor. -Less expensive compared to AC reactor -Less l...

What is the meaning of C, S, and R in non inverter compressor.

Image
Meaning of C S & R  C- Common S- Start R- Run Short trick to remember. Can She Run Can - C She - S Run- R How to decide common start and run. By check continuity. • The lowest ohm reading is between Common and Run • The middle ohm reading is between Common and Start • The highest ohm reading is between Start and Run Common is just a point between Start and Run, and therefore, the Common to Start and Run to Start readings will add up to the run to start reading. Many will tout this as a diagnostic reading you should check. It's more a mathematical fact than something useful to check. If you did see a higher reading Start to Common + Run to Common vs. Run to Start, it could really only indicate an increased resistance through the motor thermal overload that breaks common. Here is how I remember which winding resistance is which (let the mockery begin): Starting is hard , it has the highest resistance. Running is hard too but it's not as hard as starting, so it has less resist...

Types of sensors used in industrial automation.

Image
 Sensors. Sensor is a device which detects  physical property and records, indicates, and otherwise respond to it. "to ensure greater response, the engineers used electronic sensors to monitor each wheel. Types of sensors used in industrial automation. 1. Proximity sensors. Proximity sensors are able to detect the presence of nearby objects without any physical contact. It's often. emits electromagnetic field ash beam of electromagnetic radiation and looks for changes. the field of return signal.  2. Photoelectric sensors.  Photoelectric sensors are also device  that detects difference in light level recieved from the light source. The sensor is made up amplifier signal converter and a light source an output. There are three types of photoelectric sensors. A. Thru-beam sensor Two seperate device are used to make or Break beam seciever.one is emitter and second is receiver. (B) Diffused sensor, The light source and the receiver are housed in the same housing. Whe...
