In an earthen pot, water gets evaporated quickly through the pores. Cooling is caused by evaporation. Some heat energy is utilised during the process of evaporation. Since this energy is taken from the water itself, it leads to a lowering of temperature in the remaining amount of water. **Evaporative cooling: Direct evaporative cooling (open circuit) is used to lower the temperature and increase the humidity of air by using latent heat of evaporation, changing liquid water to water vapor. In this process, the energy in the air does not change. Warm dry air is changed to cool moist air. ~~~~~~~~~~~~~~~~~~Components~~~~~~~~~~~~ 1_Compressor: Isotropic Compression Process (Rotary domestic refrigerator) & Reciprocating for big unit ) 2_ Condenser : Constant Pressure Heat rejection Process (Air for domestic & Cooling tower for big unit) 3_ Expansion Device: Isenthalpic expansion (Capillary Tube for domestic refrigerator Isentropic expander for big unit) 4_Evaporator : constant pressure Heat addition process ~~~~~~~~~~~~~Others Video Links:~~~~~~~~~~~ I_ Series (RAC Lec _01) : Difference between Refrigeration , Cooling and Air Conditioning (/watch/)ANIaEIWw32ewI I_ Series (RAC Lec _02) : Room Temperature, When Condenser unit Put inside the same Room (/watch/)85MRNMZ8eQU8M I_ Series (RAC Lec _03) : Effect on Compressor capacity of different surrounding (/watch/)0J3mJMbovzao3 I_ Series (RAC Lec _04) : How COP Related to Ratings of Refrigeration System (COP Vs Ratings) I_ Series (RAC Lec _05) : Working principal of VCR Cycle I T-S & P-h Diagram (/watch/)ckCj5NeNrTaNC I_ Series (Thermodynamics Lec _01) I System & Its Types I Properties I States & Process I (/watch/)wg_m6fAQ5ANQ_ I_ Series (ET Lec _02) : Equilibrium I Condition for Reversibility I Causes of Irreversibility (/watch/)4hSVjcUG_KTGS ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Contact On: yadavmanu008@yahoo.com Post Your Interview Question in comment box or mail us
