Dry bulb temperature is the temperature of air measured by a thermometer freely exposed to the air.

• Dry bulb temperature is the most commonly used temperature measurement in HVAC engineering.

• It represents the actual temperature of the air.

• It is measured using a thermometer that is not affected by moisture or humidity.

• Dry bulb temperature is used to determine the heating and cooling loads in HVAC systems.

• For example, if ...read more

Dew point is the temperature at which air becomes saturated with water vapor, causing condensation to form.

• Dew point is the temperature at which the air can no longer hold all the water vapor it contains.

• It is the temperature at which dew or frost forms on surfaces.

• Dew point is an important factor in HVAC systems as it helps determine the potential for condensation and mold growth.

• Lower dew points indicate drier air, w...read more

ACB stands for Air Circuit Breaker and is a device used in control panels to protect electrical circuits from overloads and short circuits.

• ACB is a type of circuit breaker that operates in the air instead of oil or vacuum.

• It is commonly used in control panels of HVAC systems to protect the electrical components.

• ACBs are designed to automatically trip and interrupt the circuit in case of overcurrent or short circuit fau...read more
