Dog cages with solid and expanded metal flooring were tested while unoccupied, occupied by a 10-kg adult male beagle, and occupied by simulated loads to represent a beagle and a greyhound. Cage performances were evaluated with no direct coupling between the room air supply and the cage, and with mechanical coupling of 50% and 100% of the room air supplied directly to the cage. At each of these conditions, the room was maintained at approximately 24 degrees C and 45% relative humidity with room air exchange rates of 5, 10, and 15 changes per hr. Results indicated significant differences existed in dry-bulb and dew-point temperatures between the cage and the room. These differences, together with significant vertical gradients of air velocity and dry-bulb and dew-point temperatures within the cage were shown to be affected by room air exchange rate, cage flooring, type of coupling, and cage load.
对带有实心金属地板和网眼金属地板的狗笼进行了测试,测试时狗笼为空置状态、由一只10千克重的成年雄性比格犬占据,以及由模拟负载占据以分别代表一只比格犬和一只灵缇犬。在房间空气供应与狗笼之间没有直接耦合的情况下,以及在将50%和100%的房间空气直接供应到狗笼的机械耦合情况下,对狗笼性能进行了评估。在上述每种条件下,房间温度保持在约24摄氏度,相对湿度保持在45%,房间空气交换率分别为每小时5次、10次和15次。结果表明,狗笼与房间之间的干球温度和露点温度存在显著差异。这些差异,连同狗笼内空气速度、干球温度和露点温度的显著垂直梯度,被证明受到房间空气交换率、狗笼地板、耦合类型和狗笼负载的影响。
