Lecture 7: HVAC Course (What is Heat & Mode of Heat Transfer?)
Heat is the form of energy which transfer from high temperature to low temperature.
Heat :- 1) Sensible Heat
2) Latent Heat
Sensible Heat :- Sensible Heat is that heat which changes the temperature of the system without change it phase.
Sensible heat as name that heat you can feel.
Latent Heat :- Latent Heat is that heat which changes the phase of substance or system without change of temperature.
Total Heat of System :- Latent Heat + Sensible Heat Total heat expressed in Ton of Refrigeration.
MODE OF HEAT TRANSFER
Heat transfer takes place by three methods:
1)Conduction 2) Convection 3) Radiation
