    • The invention relates to a method for testing the tightness of refrigerating machines, particularly air conditioners in motor vehicles, according to which the apparatus that is to be tested is impinged upon by a gas at excess pressure. The aim of the invention is to create a method which detects all leaks, the size of which has an impact on the environment and health, while requiring substantially less effort to be implemented. Said aim is achieved by separating the adapters (7; 8) of a filling and measuring device from the air conditioner following the first test, connecting the adapters (7; 8) of a second measuring device to the air conditioner after an extended period of time, and comparing the test results thereof with the results of the first test, whereupon the air conditioner is deaerated and separated from the adapters (7; 8) of the second measuring device.

    • PURPOSE:To avoid the mixing between heating fluid and heated fluid and to inhibit the contamination of them by a method wherein a leakage of heating fluid and heated fluid or thermal medium is sensed by an increased or decreased amount of thermal medium in the closed container and a leakage at the thermal conduction part is sensed by a variation in state of the thermal medium. CONSTITUTION:Thermal medium is guided to a heat exchanger B by a pump 7 from a heat exchanger A through a pipe 5 from the thermal medium amount holding volume sensor part 8 and furthr circulated through the pipe 6. Then, the thermal medium is heated by the heating fluid in the pipe 3 at the heat exchanging part A, thereafter it is passed through the pipe 5 and guided to the heat exchanger B, gives heat to the heated medium in the pipe 4 and applied to the desired application. The holding volume of the thermal medium is sensed by a liquid level sensor 9 in the thermal medium holding volume sensor 8, thereby the flowing-out of the thermal medium or heating or flowing of the heated fluid can be detected. That is, in case that the liquid surface can be measured correctly, even a small amount of leakage can be detected in reference to a specific volume of the thermal medium on the basis of the temperature of the thermal medium and thus the circulation pump for the thermal medium is stopped, a pressure of the thermal medium is decreased, the mixing of the thermal medium into the heating fluid or heated fluid can be prevented.
    • 目的:为了避免加热流体和加热流体之间的混合,并通过一种方法来抑制它们的污染,其中通过在密封容器中增加或减少量的热介质来感测加热流体和加热流体或热介质的泄漏, 通过热介质的状态变化来感测热传导部分处的泄漏。 构成:热介质通过泵7从热交换器A通过管5从热介质量保持体积传感器部分8引导到热交换器B,并通过管6循环。然后,热介质被加热 在热交换部件A中的管3中的加热流体,然后通过管5并被引导到热交换器B,向管4中的加热介质发热并施加到所需的应用。 热介质的保持体积由热介质保持体积传感器8中的液位传感器9感测,从而可以检测热介质的流出或加热流体的加热或流动。 也就是说,在可以正确地测量液面的情况下,即使基于热介质的温度,也可以根据热介质的温度检测相当于热介质的体积的少量的泄漏,因此, 热介质停止,热介质的压力降低,可以防止热介质混合到加热流体或加热流体中。
