摘要
使用喷淋降温系统可以缓解奶牛热应激,但是考虑到节水及环境保护需要提高用水效率。文章主要综述了几种典型热应激状态判定条件,环境因素(温度、湿度、风速和热辐射)和喷淋参数(水滴粒径、喷淋时间和喷头流量)对喷淋降温效果的影响,以期为研发自动喷淋控制系统提供参考。
Spray cooling systems can relieve heat stress in dairy cows,but water efficiency needs to be improved considering water saving and environmental protection.This paper mainly reviewed the influence of several typical heat stress state discriminating conditions,environmental factors(temperature,humidity,wind speed,and thermal radiation),and spray parameters(water droplet particle size,spray time and nozzle flow rate)on spray cooling effect,in order to provide reference for the development of automatic spray control system.
