Subject content and scope of application
Type and basic parameters
This standard specifies the type and application of air inlet heating unit Basic parameters. JB/T 6413--92
This standard applies to air inlet heating units (hereinafter referred to as "units") for air conditioning, ventilation, heating, etc. with a maximum working pressure not exceeding 1.3MPa and a medium of hot water or steam. ). This standard does not apply to units with electric heating, thermal oil and other heating media. 2 Types | For the unit, the air flows from right to left (left type), and the air flows from left to right (right type). 2.2 Model
Structural type: Left type uses Z, The right type is represented by Y
Rated air volume: Arabic numerals × 103m2/h Heat medium code: S for water, Q for steam
Inlet air heating unit code
Model example: || tt|| means that the heating medium is water, the air inlet volume is 3000m/h, the left-hand air inlet heating unit JRS 3-Z
