working principle of refrigerator or fridge in hindi . vapour compression cycle.
Refrigeration, or cooling process, is the removal of unwanted heat from a selected object, substance, or space and its transfer to another object, substance, or space. Removal of heat lowers the temperature and may be accomplished by use of ice, snow, chilled water or mechanical refrigeration.
portable air conditioner
The applications of refrigeration can be grouped into following four major equally important areas:1- Food processing, preservation and distribution.2- Chemical and process industries3- Special applications4- Comfort air conditioning.
The refrigerator consists of the following essential parts, those are:1- Compressor2- Condenser3- Expansion Valve4- Evaporator5- Refrigerant.
The vapour at low pressure and low temperature enters the compressor from the evaporator where it is compressed to high pressure and high temperature.This high pressure and temperature vapour refrigerant are discharged into the condenser through the discharge valve.
The condenser or cooler consists of coils of pipe in which the high pressure and temperature vapour refrigerant are cooled and condensed.The refrigerant while passing through the condenser gives up its latent heat to the surroundings condensing medium which is normally air or water.
It is also called a throttle valve. Its function is to allow the liquid refrigerant under high pressure and temperature to pass through it where it reduces its temperature and pressure.Diameter is 0.6 mmlength is 2 meter.
Evaporator It also consists of coils of pipe in which liquid-vapour refrigerant at low pressure and temperature is evaporated and converted into vapour refrigerant at low pressure and temperature.
RefrigerantA refrigerant is a substance or mixture, usually a fluid, used in a heat pump and refrigeration cycle In most cycles it undergoes phase transitions from a liquid to a gas and back again R-32 Difluoromethane CH2F2 R-132a Dichloro-difluoroethane C2H2F2Cl2 R-410A is a mixture of difluoromethane (CH2F2, called R-32) and pentafluoroethane (CHF2CF3, called R-125) R-600a Isobutane C4H10 or CH(CH3)2CH3

Sir Air conditioning cooling and heating system calculation ke bare main ek video bana dete tho achha hota.

[@saralmechanical]

ok

[@moonshiekh1100]

What pressure nd temperature you have shown in diagram ,is it correct or you have taken roughly ? I mean to say in round figures

[@saralmechanical]

its roughly

[@nkkatara4797]

Room ki jo hot air ye vo room se out ho kaise hoti hai

[@saralmechanical]

wo out nahi hoti wo evaporator se thandi hokar room mai hi circulate hoti hai

[@nobiff9717]

Sir vieo nhi chal rha h

[@moonshiekh1100]

It works on VCRS system
Am I right sir ?

[@saralmechanical]

yes u r right

[@niranjanrefrigerator.repai4898]

Sir इसका p d f hai to दीजिए sir plzz 🙏

[@saralmechanical]

sorry pdf to nahi hai i will try to make pdf if u want

[@gsnmurthy2816]

sir,
please explain refrigerator pressure&vaccum and charging tests.
