UNDERSTANDING HVAC 

 

HVAC is a continuously growing industry whose  demand is increasing rapidly. Also known as climate control, HVAC stands for heating, ventilating and air conditioning. HVAC provides thermal comfort, high quality indoor air and cool air for families and businesses during the hot summer months. In virtually all areas of the World, there is a dire and escalating need for HVAC workers. HVAC is used in buses also now a days where we have HVAC buses. 

 

More people are choosing to pursue a career in the HVAC industry. Because everyone needs heating in frigid climates and air conditioning in hot climates, this field will always be in need of employees. HVAC training offers a broad education in the areas of ventilation systems, heating technology, refrigeration and air conditioning. These systems may utilize several different types of technology and methods. However, they are closely connected and many HVAC workers possess in-depth knowledge in virtually all of these departments.

 

HVAC systems can either run up the energy bill or help improve efficiencies. A better design and good layout is the key for a good HVAC system. It's all in the HVAC design and installation that will determine whether your system is friend or enemy

 

To understand how to install a proper and good HVAC system, one should first know how it works. 

 

All HVAC system design are based on the floor plan layout, allowing for ductwork and ventilation to hit every area 

Duct registers and air flow vents are strategically placed in each room for optimal air flow 

Air is pulled from the outside environment and is filtered through the ERV/HRVs, which essentially disinfects and cleans the air 

The air blows through evaporator coils which removes humidity and cools the temperature 

The blower and wheel propel the air through the HVAC

 

According to the desired needs following factors should be taken into account for better performance and efficiency of HVAC 

 

• The system or unit must be properly sized and designed to accommodate your specific building 

• Systems have sealed supply ductwork for efficient and proper energy flow 

• Balanced air flow between supply and return system 

• Filled with proper refrigerant, plus an efficiently working burner operation and draft
