日本工业标准JIS Z8703对试验地点的标准状态作了规定,其值列于表1。 JIS Z8703规定的试验地点的标准但是,标准状态1级的组合不能说就是很好了。而且实现此状态必须投入相当高的设备费用。 1.使用空调机组的恒温恒温装置的控制使用空调机组的恒温恒湿装置是较小型的。冷却装置采用直接蒸发方式。加热用热水、蒸汽或电热排管。加湿用蒸汽或热水喷雾方式或者用蒸发盘方式。有电加热排管时,加湿一般采用蒸发盘方式。 The Japanese industrial standard JIS Z8703 specifies the standard state of the test site, and its value is shown in Table 1. JIS Z8703 specifies the test site standard. However, the standard state 1 combination cannot be said to be good. And to achieve this state must invest quite high equipment costs. 1. Control using constant temperature thermostats of air conditioning units The constant temperature and humidity devices using air conditioning units are smaller. The cooling device uses direct evaporation. Heating with hot water, steam or electric heat pipe. Humidification with steam or hot water spray or evaporation tray. When there is an electric heating pipe, the humidifying plate is usually used for humidifying.
