NEW HIGHLY EFFECTIVE SYSTEM ON THE HVAC MARKET

hvac market
September 30, 2019

HVAC (heating, ventilation, and air conditioning) technology was developed more than a hundred years ago. Since the first comfort air conditioning system has been equipped in the building of the New York Stock Exchange at the beginning of the previous century, this technology has been constantly improved.

This improvement of the HVAC technology is a result of the constant customer needs growth and the desire of manufacturers to satisfy these needs. And the new product that this market provides is VAV (variable air volume) systems, which is the most advanced technology to provide the most comfortable level of temperature and air ventilation.

How Does VAV Work?

 A variable air volume (VAV) system is a new generation of the HVAC systems that can replace constant air volume (CAV) technology. The efficiency of VAV systems is proven by a high level of energy savings. This is an important question for households and enterprises nowadays, because of the economic and environmental side.

Comparison of the use of VAV and CAV systems showing that building owners can reach up to thirty percent level of energy savings. At the same time VAV provides owners with more precise temperature control because of the variable speed of an air blowing fan.

 What Are VAV System Features?

 As mentioned above, a modern air conditioning system with VAV technology provides the customer with better energy and performance efficiency levels. The use of the following additional components provides VAV systems with the following features:

  • Better efficiency and fewer needs for maintenance at the same time the owner gets because of improved motors, fan arrays, and direct-drive fans;
  • Opportunity to reduce energy use for heating to almost zero level owner gets because of energy and heat recovery systems and bypass.

One more advantage that VAV systems have is the dehumidification of incoming air before mixing it with the indoor air.

Although variable air volume technology is relatively new, it already in the process of constantly improved. That is why experts are waiting for additional features in VAV technology shortly, such as:

  • In heavy pollution areas the use of filters with higher MERV value will help to combat airborne contamination;
  • Electronically commutated motors, also known as ECM, with a sensitivity of air quality will be used for air movement into the ventilation system.

As a result of these improvements in VAV technology, customers will have an opportunity to get the HVAC system with a higher level of air quality and efficiency.

 Regulations Concerning HVAC Systems

 Nowadays the question of the air quality inside the building is very important both for the new construction and existing buildings. Rapidly increasing the demand for effective HVAC systems requires improvement in regulations. As for now, this question governed by the following:

  • State codes;
  • International Energy Conservation Code;
  • International Residential Code;
  • ENERGYSTAR;
  • ASHRAE 62.2 and 90.1.

Also known that new codes will include more requirements for ventilation equipment. Expected that the Fan Energy Index (FEI) will provide regulation of the ventilation systems efficiency, which will lead to a greater interest in regulating this issue at the system level, rather than regulating particular products.

 HVAC Systems for Homes

There are two possible types of home ventilation:

  • Natural ventilation, in which the airflow is provided by passive ventilation openings and open windows;
  • Mechanical ventilation, in which airflow is provided by the equipment that uses energy for it, and may include:
    • Exhaust fans;
    • Range hoods;
    • Whole-home ventilation systems.

As mentioned above natural type of home ventilation including airflow through the naturally-existing cracks and gaps throughout a building. But nowadays more and more attention is being paid to the issue of home sealing. It helps to retain cooling and heating energy and increases the level of comfort. But when all of the cracks and gaps are sealed, natural ventilation does not work good enough to provide a building with a high-quality indoor air.

This is the reason why the importance of mechanical ventilation is rapidly increasing. The lack of airflow inside the home can affect the indoor air pollution and respectively low quality of the air. To prevent it building owners should pay more attention to the mechanical ventilation systems.

Professional ventilation equipment helps building owners to identify and meet ventilation needs the building. In this case, the ventilation system allows replacing stale air with a high concentration of pollutants by fresh outdoor air. Modern ventilation systems help to achieve a higher level of indoor air quality, but at the same time save building cooling and heating energy.

 How to Find the Right HVAC System?

If you need to install new heating, ventilation, and air conditioning system or upgrade an existing one, it will be better to work with a trusted contractor. Such a contractor must have enough experience and expertise in HVAC solutions implementation.

Professional specialists can help you in every stage of this process: from choosing the right solution to installation and explanation of how to use all features of the system. Trust to Certificate Contractors who will help you to make your home even more comfortable and healthy, by providing you with high-quality equipment and the same level of service.
