1. Use the spray cooling system: install the spray cooling system in the pig house, which consists of a negative pressure fan, a high-pressure water pipe, an atomizing nozzle, a small water pump, a timer, a water storage tank or a small reservoir, and is suitable for cooling the sows in the pregnant pig house. The system atomizes water into fine fog beads, drops them evenly on sows, and dissipates heat through evaporation on the body surface, and the heat is discharged to the outside with the air. The timer is generally controlled as: spray 10 minute, stop 10 minute.
2. Use the cooling wet curtain and fan cooling system: install the negative pressure fan of Yueneng and the cooling wet curtain system consisting of negative pressure fan, small water pump, closed-circuit circulation of cold water and wet curtain. Negative pressure fan and wet curtain are generally installed on gables or front and rear walls at both ends of pigsty respectively. The hot air outside the wet curtain is transformed into cold air after passing through the wet curtain with cold water circulation, and enters the pigsty. After a period of time, close the wet curtain, wait for the temperature of the pigsty to rise, and then turn on the fan at the other end to pump out the hot air. Suitable for cooling in male pig house, pregnant house and delivery room.
3. Use air cooler cooling system: The cooling system of Guangdong Energy Air Cooler, which consists of air cooler, air duct, small water pump, reservoir or small well, water inlet pipe and negative pressure fan, is suitable for the cooling of boar house, empty pregnant house, pregnant sow house and delivery room, and its principle is basically the same as that of wet curtain cooling.
