地下水源热泵系统在密闭式肉鸡舍的应用效果分析

Effect of Heating System by Water-source Heat Pump on Confined Poultry House

为研究地下水源热泵系统供暖对规模化密闭式肉鸡舍环境参数及肉仔鸡生产性能的影响,选择3栋鸡舍为研究对象,每天8:00和20:00测定密闭式鸡舍内的温度、相对湿度和氨气水平,每周测定肉仔鸡的体质量,并统计死淘率。结果显示,在规模化肉鸡养殖生产过程中采用单井最大取水量100 m^3/h、出水温度53℃的1 000 m地下水源热泵系统供暖,批出栏36万只肉鸡养殖场供暖最远端肉鸡舍内温度为27.07~34.98℃,相对湿度为56.38%~64.98%,氨气水平为0.50~11.45 mg/m^3,42日龄肉鸡出栏体质量较标准品种体质量低0.26%~3.30%,死淘率为4.34%~5.66%,表明地下水源热泵系统供暖在规模肉鸡养殖中可行。

To study the effect of heating by water heat pump system on the environmental parameter and growth performance of broiler in confined poultry house. Three poultry house were empolyed to caryy out the experiment. The temperature,relative humidity and ammonia concentration in the house were measured at8： 00 and 20： 00 every day. The body weight and mortality rate of the broilers in the house were also measured. The results showed that in the production process of large-scale broiler breeding,in a farm with scale of raise 360 thousands chickens in one batch. Heating by water-source heat pump system with 1 000 meters geothermal well（The maximum water intake in one well was 100 m^3/h,the water temperature was53 ℃） could keep the temperature of the outermost poultry house at 27. 07—34. 98 ℃,the relative humidity at 56. 38% —64. 98% and the ammonia concentration at 0. 50—11. 45 mg/m3. The weight of 42 d broilers,raised in the heating poultry house,were lower than the standard weight of the same variety of broilers（0. 26% —3. 30%）,and the mortality rate were about 4. 34% —5. 66%. In conclusion,in scale broiler breeding,heating by water-source heat pump system was feasible.
