Refrigeration is the process of removing heat from a substance or space to lower its temperature.

• Refrigeration is used in various industries such as food preservation, medicine, and air conditioning.

• It involves the use of refrigerants, which are substances that can absorb and release heat.

• The process of refrigeration involves compressing the refrigerant, condensing it into a liquid, and then expanding it to evaporate a...read more

1 ton refrigeration is the amount of heat required to melt one ton of ice in 24 hours.

• 1 ton refrigeration is equal to 12,000 BTU/hr or 3.517 kW.

• It is a unit of measurement used to describe the cooling capacity of a refrigeration system.

• For example, a 2 ton refrigeration system can remove twice as much heat as a 1 ton system.

• The term 'ton' in 1 ton refrigeration refers to the amount of heat required to melt one ton of i...read more

3ph induction motor works on the principle of electromagnetic induction to convert electrical energy into mechanical energy.

• Three-phase AC power is supplied to the stator winding, creating a rotating magnetic field.

• This rotating magnetic field induces a current in the rotor, which in turn creates its own magnetic field.

• The interaction between the stator and rotor magnetic fields causes the rotor to rotate, converting e

1 HP is equal to 746 watts.

• HP stands for horsepower, a unit of power used in the automotive and manufacturing industries.

• Watt is the SI unit of power.

• The conversion factor between HP and watt is 746.

Incremental encoder measures relative position changes while absolute encoder measures absolute position.

• Incremental encoder generates a series of pulses as the shaft rotates, which are used to determine the relative position change.

• Absolute encoder generates a unique digital code for each shaft position, providing absolute position information.

• Incremental encoder is simpler and less expensive, while absolute encoder i...read more
