Function of reactor in inverter AC

 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 losses compared to AC reactor

-Need to be customized for Inverter unit as

they are installed inside Inverter chassis

What is micro chanel Heat exchanger (MCHX)?

Image
Micro chanel Heat exchanger (M C H X) Micro channel is a coil type used in many evaporator (indoor unit heat exchanger) and condenser (outdoor heat exchanger) coils. You can easily identify it by its flat tubes, and its fins look like waves between the tubes. Technology was developed to use in the automobile industry and is used in radiators and automobile A/C condenser coils. These coils are made of aluminum, and we use them because of the superior heat transfer; aluminium coils have greater surface contact between the refrigerant and the metal. They also have a low  weight and smaller refrigerant charge. Aluminium coils have come under a lot of problems from technicians due to  high failure (leak rate of the condenser coils) in some systems. Some have felt these failures occur due to inherent issues with the design, while others have stated that the leaks were due to specific manufacturing issues on a few coils and that these issues are largely in the past. No matter how you feel, it

Psychrometric chart.

Image
 Psychometric chart. Graphical representation of psychometric properties is called psychometric chart. In this chart dry bulb temperature lies on x-axis (abscissa). And specific humidity lies on y-axis (ordinate). 1. Dry bulb temperature line. In psychometric chart dry bulb temperature lines draws  vertical and parallel to ordinate at definite distance. Each lines draw in periods of 5 degree celcious. Generally dry bulb temperature shows -6 degree celcious to 45 degree celcious. 2. Specific humidity lines. In psychometric chart specific humidity lines draws as horizontal lines and parallel to abscissa at definite distance. Generally in psychometric chart specific humidity lies between 0 to 30 gram per KG. Specific humidity lines are also called moisture content line. 3. Dew point temperature lines. In psychometric chart dew point temperature lines draws as parallel to abscissa distance between two D.P.T. lines are not same. 4. Wet bulb temperature lines. In psychometric chart wet bulb
