关于空调的堵风试验

请教各位：19.8中“如果温升大约为1K(1℃)/min，则该实验就完成了。”请问，其中的温升指的是谁的温升？其中的试验指的是什么试验？

19.8 All appliances provided with supplementary heaters are subjected to the following test
under the conditions specified in Clause 11:

After the airflow conditions specified are established, the indoor airflow is restricted to such
an extent that the temperature of the air in the outlet, measured by means of the
thermocouple grid (see 11.3), is 3 K below the temperature obtained after a temperature
limiting control, a motor protective device, a pressure switch or similar device operates for
the first time as a result of slowly restricting the free area of the inlet.

This is achieved if the temperature rise is approximately 1 K per min.

It is necessary to restrict the free area of the inlet until the first of the protective devices
operates and then operation is resumed with sufficient restriction so that the temperature of
the discharge air is 3 K below the temperature at the moment of cut-off.

Appliances are operated at rated voltage or at the upper limit of the rated voltage range.
NOTE 101 To facilitate this test, the protective device which has operated may be short-circuited once the temperature at which it operates has been determined.

谁能把整个试验过程大致描述一下？

没搞过空调，顶起先！顺便也学习学习！

19.8中这句雷人的话“温升大约为1K(1℃)/min，则该实验就完成了。”指的应该是试验时封堵进气口的速度不要太快也不要太慢，让出风口的温度以大约1K(1℃)/min的速度上升直至比........(此处略去N个字)低3K(℃)，这样，试验就完成了。
