GB/T 26623-2011Design requirements of tunnel ventilation system for animal housing (English PDF)

3.1 Longitudinal ventilation

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.

4.1 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.
