To fully comprehend the ways of installing a high-velocity HVAC (heating, ventilation, and air-conditioning) system, one must first know what a high-velocity HVAC is and what exactly it does.
Simply put, high-velocity HVAC is designed for fitting into structures that have architectural restrictions or space limitations. A large number of modern-day individuals choose it to keep the cooling and heating components hidden.
The high-velocity HVAC metes out conditioned air through flexible, pre-insulated tubing that has a diameter of two inches and is fed through the walls and around the obstructions. The system relies on sound attenuation resources to absorb the regenerated and airborne noise, thus, assuring cent percent quietude. The center of the system has a coil handler and cabinet blower that can be squeezed into the tightest areas.
Mentioned below are the major steps of successful high-velocity HVAC installation as approved by Title 24 San Diego. Please check them out right now.
Load calculation is the foremost and the most significant step. Get this – every person living in a house is 100 extra BTUs, every window in a house is 1000 extra BTUs, and every door in a house is 1000 extra BTUs.
So if the concerning residential property is of 2500 square feet area, and has three exterior doors, twelve windows, and occupied by four people, plug into the following formula.
• 2500 x 25 = 62500 base BTU
• 3 x 1000 = 3000
• 12 x 1000 = 12000
• 4 x 400 = 1600
• 62500 + 3000 + 12000 + 1600 = 79100 BTU
There are a couple other factors that can impact or falsify the stated BTUs. For precision, get in touch with a qualified engineer.
Find an Appropriate Location for Fan Coils
The fan coil needs to be located in a completely unconditioned area. Attics and garages are acceptable as long they are protected from the weather conditions and the local safety codes are fulfilled. Some fan coils can be placed in a conditioned area like closet, basement, and utility rooms too.
Construct a Sturdy Platform
Construct a platform based on the dimension of the fan coil. It is necessary to use two-by-eight-inch resilient lumber and at least half an inch of plywood. Always apply the given isolation strips for optimal performance. For areas where the fan coil is suspended, please suspend the platform, too, with threaded rods.
Connect Condensate Drain
Connect the condensate drain cautiously with the fan coil. Try running the condensate drain from the trap in accordance with the safety protocols, of course. Make sure the drain line is inclined approximately ¼ inch each foot. Never connect condensate lines to any close drain. Use secondary drain pans for the overhead HVACs.
Connect Refrigerant Lines
Finally, connect the refrigerant line that lies in the outdoor condenser to the indoor fan coil. Always adhere to the manufacturer’s instructions in terms of installation, sizing, charging, trapping, and using filter dryers.
All types of electrical installations need to conform to the latest requirements of Title 24 San Diego. In case of HVAC systems, the mandate asks the homeowners or the interior designers to first test the ducts, determine the actual size of the equipment, and invest in smart thermostats. A detailed report will tell everything one needs to know regarding the necessary compliance.
