3 Terms and Definitions
GB/T 19525.1 determined and the following terms and definitions apply to this standard.
3.1
Longitudinal ventilation tunnelventilation
Installing an exhaust fan in the corral dirt road near the gable end gable or side wall, form a gas in the corral along the longitudinal direction
Ventilation flow.
4 design requirements
4.1 ventilation rate determination
4.1.1 calculated according to the recommended ventilation requirements
Longitudinal ventilation design ventilation system according to the recommended ventilation requirements Q (m3/h), according to equation (1) calculations.
Q = R × n (1)
Where.
R --- per head (only) recommended ventilation requirements of animals (see Appendix A), in units of cubic meters per hour per head (only) [m3/(h · Head)];
n --- number of animals, units (only).
4.1.2 Calculation on the recommendation of Winds
Winds on the recommendation of the longitudinal ventilation design ventilation systems Q (m3/h), according to equation (2) calculation.
Q = V × A × 3600 (2)
Where.
V --- animal recommendation wind speed (see Appendix B), in meters per second (m/s);
A --- animal building cross-sectional area, in square meters (m2).
Ventilation 4.1.3 4.1.1 and 4.1.2 according to the two methods are not the same, whichever is greater.
4.2 air intake design
4.2.1 Basic requirements intake port
4.2.1.1 should have appropriate air intake area to ensure the speed of the airflow through the winter when more than 4m/s, the speed of air flow through the summer
1m/s ~ 2m/s.
4.2.1.2 summer surface flow through animal husbandry, winter air does not blow directly to the animal body.
