This is the 2nd date of a 2 part series. It can also be watched stand-alone. In this module, we will finish our discussion about energy savings for packaged rooftop units by taking about VFDs fan systems. Then we will continue on with heat pumps and VRF systems.
o RTU Staged Air Volume (SAV)
1. How is SAV different than VAV?
2. What good is a VFD on a “constant volume” system?
3. VFD or ECM?
4. How is it controlled?
5. Is it required by energy code?
o Heat Pump Systems
Discussion of Heating System Options
How does a heat pump work?
Operating cost comparisons to electric heat, natural gas, and propane
Do heat pumps work in cold climates?
Heat pump types: air source, water source, and geothermal
Auxiliary Heating Choices & Hybrid Systems
o Variable Refrigerant Flow (VRF) Systems
2-pipe Heat Pumps & 3-pipe Heat Reclaim
AHRI Efficiency Ratings
Energy Comparison to other system types
