Learn Basics of Technical Manuals J, S, & D
There’s a special touch involved in creating the right atmosphere. After all, not every party can be saved by good drinks and music alone. The atmosphere is all about comfort, and if there's anything we’ve learned, it's that comfort is all about design.
Sensing the change in the air, we’ve had to master a couple of skills—skills refined by 45 years of experience to enable us to stand as experts in the best practices of HVAC installations. Like most things, best practices come in the form of instructions.
A proper HVAC contractor knows how to follow these in order to avoid inefficiencies that counter comfort. Naturally, you should base your expertise on the knowledge assimilated in the HVAC technical manuals: Manual J, S, and D.
What is Manual J?
Before any room can be outfitted with the right HVAC system, it first needs the right calculations. The outcome of following Manual J specifications is threefold:
1. Energy efficiency
2. Effective pricing
3. The right fit of HVAC system
This requires a measurement of the temperature and level of humidity in a room, as it determines how much-conditioned air needs to be circulated.
Whether this air makes a difference is also influenced by factors such as ventilation and insulation, indicating how easily this air is trapped or released. These and other load calculations become necessary before sizing and selection of HVAC units and duct systems can even be made.
Manual S and Manual D
After an HVAC contractor has proven their hand at the numbers, they need to access the right equipment. Manual S provides information on sizing the right parts from the best performing manufacturers. Once this selection has been made, a professional installer can assemble the pieces into a proper duct system design, the parameters of which are set out by Manual D.
