I. Overview

1. VAV is the abbreviation of Variable Air Volume. In the --r adjustment system, in order to cope with the changes in the end load, when the cold/thermal media flow is unchanged, it is necessary to adjust the --r volume to adjust the cold/calories. Transport to meet the needs of changes. VAV (variable --r-conditioning system) is a design standard by changing the amount of --r supply, "Specifications for Heating, Ventilation and Air Regulatory Design" (GBJ19-87-2003). "GBJ304-2002" (GBJ304-2002) "Concise Ventilation Design Handbook" (GB50194-2002) (GB50194-2002) "Compressor, Winder, Pump Installation Engineering Construction and Acceptance Specifications" (JBJ29-2002) "Electrical Installation Installation Project Low-voltage Electric Construction and Acceptance Specifications "(GB50254-96)" Comprehensive Emissions Emissions Emissions of --r pollutants "(GB16297-1996). "Environmental Air Quality Standards" (GB3095-1996), "Urban Regional Environmental Noise Standard" (GB3096-93) "Architectural Design Fire Fire Specifications" (GB50016-2006), and "Public Architecture Energy Conservation Design Standards" (GB50189-2005).

2. Tr--ning devices are also suitable for ordinary institutions, technical schools, vocational tr--ning schools, vocational education centers, appr--sal stations/institutions, and refrigeration majors "Refrigeration Equipment M--ntenance Industry (**)", "Principles and M--ntenance of Refrigeration Equipment", " The operation and installation and m--ntenance of refrigeration --r -conditioning devices "," Central Air Conditioner (Primary, Intermediate, **) "," Principles and M--ntenance of Home Refrigeration Equipment "and other courses.
