Heating, Ventilation and Air-Conditioning
HEAT :Heat is a flow of energy due to temperature differences
TWO TYPES
1. SENSIBLE HEAT
2. LATENT HEAT
SENSIBLE HEAT: The heat you can sense by Thermometer is called Sensible Heat
LATENT HEAT: Latent heat is hidden or invisible heat. It is the amount of heat added or removed from a body to change its state without changing the temperature
TEMPERATURE: How Hot or Cold an object is called Temperature
Humidity: Humidity is the amount of water vapor in the air. Too much or too little humidity can be dangerous.
AIR-CONDITIONING: The control of temperature, humidity, purity, and motion of air in an enclosed space, independent of outside conditions.
