How Does an HVAC System Work?

How Does an HVAC System Work?

The term HVAC stands for heating, ventilation and air conditioning, a system used to control the temperature in a space as well as humidity and quality of air. In a big building, the system needs to be able to function based on comfort need as well as meet the size of the space. The HVAC system must transfer heat and moisture into and out of the air to control the temperature level, as well as the level of air pollutants. This is done by removing the pollutants directly or by diluting them.

Chilled Beams vs. Chilled Ceiling

Chilled Beams vs. Chilled Ceiling

Chilled beams are often compared to a chilled ceiling though there is a distinguishable difference between the two. A chilled ceiling will use pipes with water flow as a chilled beam system. However, the pipes of the ceiling will be placed behind metal ceiling plates. Then, the plates are heated or cooled based on the method of convection rather than the pipes providing the heating or cooling method.

5 Types of IT Environment Heat Removal Methods

5 Types of IT Environment Heat Removal Methods

Data centers and IT rooms are becoming an integral part of businesses across the globe. And, as technology continues to change and evolve, computing equipment is being created in smaller sizes. However, the smaller size uses more electricity and can generate more heat, which creates a need for heat removal. So, it is essential that such spaces have precision cooling and heat rejection equipment in order for the equipment to stay at an even temperature and avoid overheating. There are several heat removal methods in which cooling equipment can be used to mediate the high heat generated by the computing equipment.
