What is Refrigeration?   How Domestic Refrigerator works? Refrigeration defined as, the temperature of refrigeration system maintain below atmospheric temperature is known as Refrigeration System. R134a is a refrigerant currently used in refrigeration system. How Domestic Refrigerator Works? Domestic Refrigerator. Domestic refrigerator system mainly work on Vapour Compression System i.e. VCC. Main Components of VCC System- Hermetically sealed Compressor. Condenser. Expansion valve i.e. Capillary Tube or Thermostat Evaporator. 1) Hermetically sealed compressor- Function of compressor is to increase the pressure & temperature of vapour refrigerants by compressing refrigerated gas i.e.Freyon  Compressor consist of black color coating on it known as Hermetically  Sealed. It's function is te minimize the noise of compressor during compression.  2) Condenser- The compressed refrigerant enters in condenser in which temperature ...

Basic Information Of Two-Stroke Engine Two stroke engine is an internal combustion engine which works on Otto cycle.It works on Otto Cycle.Two-Stroke engine produced more power as compare four-stroke engines.Yamaha RX-100/135 is the best example of two-stroke engine.   Fig. OTTO CYCLE In Otto cycle, heat addition take p hilace at constant volume at stage 2-3. Heat rejection take place at constant volume at stage 4-1. 1-2:- Isentropic Compression. 2-3:- Heat addition at constant volume. 3-4:- Isentropic Expansion. 4-1:- Heat rejection at constant volume. Main Components Of Two-Stroke Engines- Crankshaft. Connecting Rod. Piston. Cylinder. Inlet port. Transport port. Exhaust port. Crankpin,Piston Pin. Spark plug. How Two-Stroke Engines Works? Here are two main strokes of two-stroke engines i.e. 1) Upward Stroke. 2)Downward Stroke. On which two two stroke engines works. Downward Stroke- In downward stroke piston's po...
