Two forms of heat are relevant in air conditioning:
1. Sensible Heat
2. Latent Heat
Sensible heat
When an object is heated, its temperature rises as heat is added. The increase in heat is called sensible heat. Similarly, when heat is removed from an object and its temperature falls, the heat removed is also called sensible heat. Heat that causes a change in temperature in an object is called sensible heat.
Latent heat
All pure substances in nature are able to change their state. Solids can become liquids (ice to water) and liquids can become gases (water to vapor) but changes such as these require the addition or removal of heat. The heat that causes these changes is called latent heat.
Latent heat however, does not affect the temperature of a substance - for example, water remains at 100°C while boiling. The heat added to keep the water boiling is latent heat. Heat that causes a change of state with no change in temperature is called latent heat.
Appreciating this difference is fundamental to understanding why refrigerant is used in cooling systems. It also explains why the terms 'total capacity' (sensible & latent heat) and 'sensible capacity' are used to define a unit's cooling capacity. During the cooling cycling, condensation forms within the unit due to the removal of latent heat from the air. Sensible capacity is the capacity required to lower the temperature and latent capacity is the capacity to remove the moisture from the air.

∙ 11y agoI think sensible heat is higher because it accompanies a change in temperature whereas in latent there is no temperature change

Latent heat - Heat energy which causes a change in phase is called latent heat.

What is the difference between sensible heat gain and latent heat gain?
When an object is hot, the temperature rises as heat is added. This increase in heat is called sensible heat. Solids can become liquids and liquids can become gases but changes like this require the addition or removal of heat. The heat that causes these changes is called latent heat.
Difference between sensible heat and latent heat?
Sensible heat is heat supplied or taken away and causes an immediate change in temperature without changing the state. While latent heat is heat supplied or taken away and causes a change in state without change in temperature. This difference can be applied to the certain properties of water/steam. This is called the thermodynamics properties of steam.
Can a sensible heat and latent heat transfers be read with a thermometer?
yes
Can sensible heat and latent heat transfers be read with a thermometer?
yes
What is the difference between surface condenser and overhead condenser?
Surface condenser is a heat exchanger in which latent heat only absorbed by the cooling media and heat exchange mostly takes place on availble just surface of the tube bundle. Overhead condenses is also a heat exchanger in which latent heat and somewhat sensible heat also removed from the fluid

What is released as sensible heat during the formation of clouds?
Latent heat.
Can a sensible heat and latent heat transfers be read with a thermometer?
yes
Can sensible heat and latent heat transfers be read with a thermometer?
yes
What do you call heat that is added or removed from a substance but does not change the state of the substance sensible heat latent heat super heat or radiation heat?
Latent Heat.

Q - What is the difference between latent heat of fusion and latent heat of solidfication?
They are the same thing. Fusion and solidification both mean the changing of a liquid to a solid.
How much heat can a central air conditioner remove?
It`s rated capacity in sensible and latent heat.
What is the difference between latent heat of fusion and latent heat of vapourization?
the heat which is absorbed by a substance for changing solid into liquid state by keeping temperature constant is called latent heat of fusion while the heat which is evolved during phase change of liquid to vapour state at constant temperature is called latent heat of vapourization

What is the difference between latent heat and heat?
Usually as we give heat to a system then temperature of the system would rise. But at the boiling point though we give enormous amount of heat the temperature would remain the same and so the heat given is said to be latent and it is used to change water from liquid state to gaseous state. Hence the name latent heat
