Conventional HVAC System
A conventional, low velocity, air-conditioning system works well, if somewhat inefficiently for most homes. First, a refrigerant liquid is cooled at the condenser on the outside of the home. Then it is transported inside to the evaporator where it is allowed to become a gas again. These steps significantly cool the temperature of the gas that is contained in a series of tubes.
The final step in the cooling process blows air across these tube. The air is then forced into the living space by a blower fan and cools the house. This process has worked very well for many decades but modern times demand modern solutions.
The main problem with a low velocity, HVAC system is that the cooled air is only immediately available in a small portion of the space. Movements in the space by people, pets or by simple conduction eventually cool the whole room but an at unacceptably slow rate. High velocity HVAC systems directly address this shortcoming.
High Velocity HVAC System
Another, more convenient solution, as their name implies, high velocity HVAC systems force air into a space at a high rate of speed. This force creates a multitude of air currents that evenly distribute the cooled air in a much shorter period of time.
High velocity HVAC systems also offer other benefits. The ductwork necessary for a high velocity system is considerably less intrusive and installed far more affordably. Due to their smaller size, the ducts can be placed far more advantageously and exactly to a customer’s specifications. Lastly, they take up a much smaller profile in a room and blend in with décor to a far greater degree.
The Edge (Goes to High Velocity Systems)
While, the traditional HVAC systems may seem to be the preferred choice as they are the tried and true, homeowners should still consider a high velocity looking to completely replace their AC systems should consider a high velocity system. Many think that they can reuse their existing ductwork however the duct work uses in high velocity systems is very different than the conventional duct work. With this last fact in mind, a high velocity HVAC system becomes far more competitive in terms of installation and operating costs.
