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.

What is the purpose of a boiler that is used on the HVAC system?
The purpose is what it was without a HVAC system ... to make heat !
How can I replace a heat exchanger in my HVAC system?
Replacing a heat exchanger in your HVAC system involves turning off the power, removing the old heat exchanger, installing the new one, and reconnecting everything. It is recommended to hire a professional HVAC technician for this task to ensure it is done safely and correctly.
What are signs of a bad hvac fan?
One that stays out late, drinks and smokes.
How do you get heat to work on a hvac unit?
need to be specific, but usually byswitching the tstat to heat and raising the temperature.
How do you adjust a heat pump defrost cycle?

How HVAC in automobile works?
HVAC basically stands as Heat ventilation and air conditioning. As the name indicates it used for cooling the engine parts
What do you mean by HVAC repair?
HVAC (Heating, Ventilation, and Air Conditioning) refers to technology of indoor or automotive environmental comfort. HVAC system design is a major subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. Refrigeration is sometimes added to the field's abbreviation as HVAC&R or HVACR, or ventilating is dropped as in HACR (such as the designation of HACR-rated circuit breakers).
What are the benefits of using Finned Tubes in HVAC systems?
Finned Tubes enhance heat transfer efficiency, reducing energy consumption in HVAC systems.
What part of an HVAC system switches the unit from air conditioning to heat and heat to air condtioning?
In HVAC (heating, ventilating, air conditioner) A thermostatic switches the unit from cooling to heat. In Heat pump unit it's the four-way valve or reverse valve. However, the thermostatic still controls it.
What are the pros and cons of using an HVAC system in a residential building?
pros comfort cons no comfort if you want to heat or cool you will be using some form of hvac
What situation would best fit the use for hvac tools?
Hvac tools make repairing Hvac systems such as heating and air conditioning systems much easier. Automotive air and heat systems also are part of Hvac systems and require their own set of tools.
