DUCT SIZING WITH SOFTWARE
COMMERCIAL, Industrial, and residential air duct system design must consider.
(1) Space availability,
(2) Noise level.
3) Air leakage.
(4) Balancing.
(5) Fire and smoke control.
(6) Initial investment cost
(7) System operating cost.
Deficiencies in duct design can result in systems that operate incorrectly or are expensive (increased energy) to own and operate. Poor design or lack of system sealing can produce inadequate airflow rates at the terminals, leading to discomfort,loss of productivity,and even adverse health effects. Lack of sound attenuation may lead to objectionable noise levels. Proper duct insulation eliminates excessive heat gain or loss.
In this chapter, system design and calculation of a system’s frictional and dynamic resistance (total pressure) to airflow are considered.Chapter 19 of the 2016 ASHRAE Handbook—HVAC Systems and Equipment examines duct construction and presents construction standards for residential, commercial, and industrial HVAC and exhaust systems. For design guidance specific to residential systems, refer to Manual D by ACCA (2014). .
McQuay DUCT SIZER
McQuay (As part of Daikin Industries) is one of the largest air conditioning, heating, ventilating and refrigeration companies in the HVAC/R industry.
Therefore, we decided to make some softwares that this company has introduced to the industry based on their experience and knowledge available for download.
Occupant comfort is the goal of all HVAC designers. Sound (or noise) is a key parameter in measuring comfort, in addition to temperature, humidity and Indoor Air Quality (IAQ). While acoustics consultants are usually involved in critical applications (such as performing arts centers), the task of creating a comfortable acoustic environment in most other applications falls on the HVAC engineer. This is because most background sound sources are generated by the HVAC equipment.
This program includes defaults, databases, and typical applications to speed up the analysis. Once the user has a basic understanding of acoustics, the program can be very helpful.
