What does “change of state’’ mean? And why is it important to air-conditioning units?

To determine

To discuss the “change of state” and important factor of air-conditioning?

Explanation

To discussed the “change of state”:

Latent heat is important in the operation of air −conditioning system because the cooling effect is derived from changing the state of liquid refrigerant to vapor .The liquid refrigerant absorbs the latent heat of vaporization making the air cooler air is then into the passenger compartment.

Three common state of changing of state:

  • Solid
  • Liquid
  • Gaseous

Solid:

In the solid state, the particles stay more or less in contact with each other they are still free to move and can slide past one another easily .in the solid stat

Liquid:

In the liquid state, the molecular motion and the molecular attraction are more balanced.

Gaseous:

In the gaseous state, the molecular motion has completely overcome any attraction between the particles

The four important factors for air conditioning are:

  • Temperature of air
  • Humidity of air
  • Purity of air
  • Motion of air

Temperature of air:

In air conditioning the control of temperature means the maintenance of any desired temperature within an enclosed space even though the temperature of the outside air is above or below the desired room temperature. This is accomplished either by the addition or removal of heat from the enclosed space as and when demanded ...
