#ventilation
Energy-efficient homes – new and existing – require mechanical ventilation to maintain indoor air quality. This session will discuss why ventilation is necessary, the roles of intermittent, spot, and whole-house ventilation, options for achieving each type of ventilation, ASHRAE 62.2 standards, system sizing, and fundamentals of proper installation. The ventilation requirements of many state codes, IECC and the new 2015 Michigan Residential Code will also be covered.
Lessoned Learned
• Understand the necessity of ventilation and fundamentals of ASHRAE 62.2 – 2010 & 2013
• Understand the difference in Whole-House, Intermittent and Spot ventilation
• Evaluate the differences in Exhaust, Supply and Balanced ventilation options to meet ASHRAE Standards
• Calculate the proper size of a residential ventilation system based on the size of the home and number of occupants
Continuing Education Units (CEUS) - 1 hour
• GBCI
• AIA(HSW)
• NARI Green
• Certified Green Professional (CGP)
• AIBD
• Certified Green Home Professional (CGHP)
• May be applicable to your state-based design or contractor license*

In this video is how to VRV/VRF REFNET SIZING layout | VRV/VRF System PIPE SIZING As you can see on the table there are the size of the pipe and the kg/m for add the refrigerant to each size of the pipe installation on the site. Please take note that all the pipe is following the the liquid pipe. After the table I give you After that I think it is easy for you to understand of how to calculate the additional refrigerant charge to the VRV.
