what is Air conditioning? |
A form of air treatment whereby temperature, humidity, ventilation and air cleanliness are all controlled within limits determined by the requirements of the air conditioned enclosure |
the process of heat removal |
|
|
what is Sensible heat? |
If a change of enthalpy can be sensed as a change of temperature, it is called sensible heat |
can be know by just touching |
|
|
Basic vapour compression cycle |
Heat is put into the fluid at the lower temperature and pressure and provides the latent heat to make it boil and change to a vapour, this vapour is then mechanically compressed to a higher pressure and a corresponding saturation temperature at which its latent heat can be rejected so that it changes back to a liquid |
change i enthalpies between the fluid entering and the vapour leaving the evaporator |
|
|
Coefficient of performance??? |
Ratio of the cooling effect to the input compressor power,, (Q1-Q2) /Wc |
related to efficiency |
