规模化猪场降温系统研究综述
Research review on cooling systems in large-scale pig farms
摘要：
针对规模化现代养殖模式所带来的一系列问题，分别从冷源型式、末端处理型式和通风型式对猪场降温系统进行了综述：分析了家畜养殖业常见冷源的经济性与运行可靠性，指出了人工冷源在规模化猪场应用的可行性；阐述了常见末端处理型式的降温原理与降温效果；对比了常见末端处理型式对猪舍内湿度的控制能力，并指出规模化猪场应对高温高湿天气的有效办法是降低送风含湿量；对比了不同通风型式之间的差异，并论证了个性化送风相较于全面通风更具有优越性，正压通风优于负压通风。
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.
