HVAC SYSTEM DESIGN

MSI can help you design your Heating Ventilation & Air Conditioning (HVAC) system for your residence. MSI shall design your residential HVAC system in accordance with the American Society of Heating, Refrigeration, and Air-conditioning Engineers (ASHRAE) standards and/or per ACCA (Air Conditioning Contractors of America) design procedure.

Load and CFM Calculations

Building design heat loss rate and design heat gain rate, shall be determined using a method based on ASHRAE or ACCA Manual J to determine the system requirements:

	Perform load calculations
	Calculate heat loss and heat gain of each room and total room load
	Calculate CFM requirements for each room and total room CFM

Air Distribution System Design

We layout and size air distribution system based on ACCA Manual D:

	Prepare air distribution system layout and plan duct paths
	Determine registers positions
	Optimize room air circulation
	Size, locate and optimize returns

System Selection

We size and select the HVAC system based on ACCA Manual S:

	Size equipment to sensible loads
	Specify and select equipment using available manufacturers' data and guidelines
