規?;i場降溫系統研究綜述
Research review on cooling systems in large-scale pig farms
摘要:
針對規?;F代養殖模式所帶來的一系列問題,分別從冷源型式、末端處理型式和通風型式對豬場降溫系統進行了綜述:分析了家畜養殖業常見冷源的經濟性與運行可靠性,指出了人工冷源在規?;i場應用的可行性;闡述了常見末端處理型式的降溫原理與降溫效果;對比了常見末端處理型式對豬舍內濕度的控制能力,并指出規?;i場應對高溫高濕天氣的有效辦法是降低送風含濕量;對比了不同通風型式之間的差異,并論證了個性化送風相較于全面通風更具有優越性,正壓通風優于負壓通風。
Abstract:
Aiming at a series of problems brought by the large-scale modern breeding mode, the cooling systems of the pig farm are reviewed from the cold source type, the end treatment type and the ventilation type. The economy and operational reliability of common cold sources in livestock breeding are analysed, and the feasibility of artificial cold sources in large-scale pig farms is pointed out. The cooling principle and cooling effect of common end treatment types are explained. The control ability of common end treatment types on the humidity in the pig house is compared, and it is pointed out that the effective way for large-scale pig farms to cope with high temperature and high humidity weather is to reduce the moisture content of supply air. The differences between different ventilation types are compared, and it is demonstrated that personalized supply air is more superior than comprehensive ventilation, and positive pressure ventilation is better than negative pressure ventilation.
