【摘要】 本文对天津市郊区两种类型犊牛舍的环境进行了测定,一种类型为半开放式,另一种为联栋式。在每种类型犊牛舍的中央纵轴上均匀选取三个测定点,每个测定点距离地面1.0m,对其温度、相对湿度、风速、CO2浓度和NH3浓度进行了测定。测定结果表明,半开放式犊牛舍冬季一天平均气温低达4.4℃,不能满足犊牛正常生长的需要;联栋式犊牛舍内空气质量好,气温较高,但舍内南北两侧温度差异较大,南侧一天平均气温在10℃左右,北侧只有6℃左右,应加强联栋式犊牛舍内北侧外围护结构的保温性。当联栋式犊牛舍温度过低时,使用红外线灯可以使舍内温度提高2~3℃。更多还原

【Abstract】 The housing condition of two types calf houses was determined in the suburb of Tianjin city.One type was half-open house,another for united-building house.Three determination points were set l along the the centra vertical axis in two types calf houses.Temperature,relative humidity,wind velocity and the concentration of CO 2 and NH 3 were determined at each determination point,from which to ground one metre distance.Results showed that temperature of half-open calf house was only 4.4 ℃ in winter,which could not meet the needs of calves normal growth.Meanwhile,gas quality was better and temperature was higher in united-building calf house,but for temperature there was larger difference between the north and the south in united-building calf house.The average temperature was around 10 ℃ in the south,while only around 6 ℃ in the north.Therefore,Heat preservation of building envelopes and enclosures should be improved in the north of the united-building calf house.when temperature of the united-building calf house is too low,using infrared lamp can raise temperature by 2-3℃.更多还原
