In the farrowing houses the electric dynamic katathermometer (EDK) was used to determine the thermal conditions in boxes for piglets heated by electric infraradiators (EIZ) with an input of 525 W. The density of heat flow of the EDK sensor in the boxes which characterizes the cooling properties of this environment was zero or only very low if the infraradiators were installed 60 to 70 cm above the floor of the boxes, i. e. so as to temper the air to a temperature recommended by the standard. This is apparently caused by the relatively great radiation from the infraradiator which is not registered by the mercury thermometer but is absorbed by the body surface of the piglets and may lead to their overheating. A desirable increase in the cooling properties of the box environment and of the other spaces of the farrowing house was achieved by decreasing the infraradiator input to 260 W and suspending them 50 cm above the floor of the boxes. Their fixation at a greater height allowed the further effective regulation of the heat conditions in the boxes while at the same time cutting down electric energy consumption by a half.
在产仔舍中，使用电动动态低温温度计（EDK）来测定由输入功率为525瓦的电红外线加热器（EIZ）加热的仔猪保育箱内的热状况。如果红外线加热器安装在保育箱地面上方60至70厘米处，即按照标准将空气调节到推荐温度，那么保育箱内EDK传感器的热流密度（它表征了这种环境的冷却特性）为零或极低。这显然是由于红外线加热器的辐射相对较大，水银温度计无法记录，但仔猪体表会吸收，这可能导致它们过热。通过将红外线加热器的输入功率降至260瓦，并将其悬挂在保育箱地面上方50厘米处，保育箱环境以及产仔舍其他空间的冷却特性实现了理想的提升。将它们固定在更高的位置可以进一步有效调节保育箱内的热状况，同时将电能消耗降低一半。
