Problems solved by technology

In conventional gas analysis, a gas chromatograph has been used as a device for determining gas components, but the gas chromatograph itself is large and difficult to transport. Therefore, it is necessary to transport the gas sample taken from the extraction tank of the refrigerator to an analytical facility. facility of the device
Therefore, it takes a long time until the result of the composition analysis of the noncondensable gas is obtained, and it is difficult for emergency maintenance personnel to take appropriate countermeasures in this case.
In addition, when the sample gas is introduced into the gas chromatograph, air may be mixed in, which will cause errors in the ratio between air and hydrogen that should be measured.
[0006] The same problem occurs not only in absorption refrigerators, but also in other devices that use the absorption of absorbents to move heat, such as absorption cold water heaters and absorption heat pumps.

Embodiment Construction

[0044] Below, refer to Figure 1 to Figure 12 Embodiments of the gas component determination method and apparatus according to the present invention will be described. In addition, in Figure 1 to Figure 12 In , the same or equivalent components are assigned the same symbols and descriptions are omitted.

[0045] figure 1 It is a schematic diagram showing the gas component determination device according to the first embodiment of the present invention. Such as figure 1 As shown, the gas component determination device includes two airtight containers, namely, a first container (tank A) 1 and a second container (tank B) 2 . Furthermore, the first container 1 and the second container 2 are connected by a pipe 4 having an openable and closable valve V3 and an orifice 3 . In this embodiment, the first container 1 and the second container 2 use the same container with a capacity of 10 liters (L) (if the accuracy of measurement and transportability are considered, it can be sa...

Abstract

The aim of the present invention is to provide an absorption refrigerating machine or absorption water cooling / heating device having an apparatus for judging compositions of a non-condensable gas simply and capable of deciding a necessary maintenance by itself. The residual non-condensable gas of a device for transferring heat by the absorption of an absorbent of the absorption refrigerating machine and the like is guided into a first seal container, a seal second container is vacuum, a pipeline for connecting the first container (1) and the second container (2) and having a orifice (3) is switched on to communicate the first container (1) and the second container (2) to measure a duration time until the pressures of the first container (1) and the second container (2).

Description

technical field [0001] The present invention relates to a gas component determination method for determining the components of noncondensable gases such as hydrogen and air remaining in devices such as absorption refrigerators, absorption cold and hot water heaters, and absorption heat pumps that transfer heat through the absorption of absorbents and the like. Gas composition determination device. Background technique [0002] An absorption refrigerating machine is composed of a regenerator, a condenser, an evaporator, an absorber, and pipes connecting them. If water is used as the refrigerant and lithium bromide aqueous solution (lithium bromide aqueous solution) is used as the absorption liquid (absorbent), it will react with the metal of the equipment components during the absorption cycle to generate hydrogen gas. In addition, although the absorption refrigerator is in a high vacuum state, it is difficult to completely prevent the intrusion of atmospheric components (ai...
