The pyroconductivity of the vacuum insulation part after the vacuum insulation part of the vacuum insulation part 1 and comparative example of and then having made present embodiment 1 is all this identical value of 1.8mW/ (mK).Afterwards, when above-mentioned vacuum insulation part being taken care of 30 under the environment of temperature 25 DEG C, relative moisture 60%, the increasing amount of the pyroconductivity of the vacuum insulation part of comparative example is 0.4mW/ (mK), and on the other hand, the increasing amount of the pyroconductivity of the vacuum insulation part 1 of present embodiment 1 is 0.2mW/ (mK).
In the vacuum insulation part 1 of present embodiment 1, not there is the laminate film as protecting sheet used in the vacuum insulation part of comparative example, and the second adsorption element 5 is surrounded by the first adsorption element 4 and above-mentioned chipware 2.Thus, the ventilation of the second adsorption element 5 is not hindered.Therefore, in present embodiment 1, do not reduce the adsorption rate of the heat-conducting gas in vacuum insulation part 1, thus can obtain and pyroconductivity can be maintained lower vacuum insulation part 1 for a long time.
< example 3 >
Example 3 is in the vacuum insulation part 1 of present embodiment 1, the example that adsorption rate when being 4 times of the first sorbent 40 to the adsorption rate of the moisture making the second sorbent 50 is tested.
In the vacuum insulation part 1 of present embodiment 1, be on average 3mm and the adsorption rate of moisture is that except the unslaked lime (calcium oxide) of 4 times of the first sorbent 40, all the other structures are identical with example 1 ~ 2 except the second sorbent 50 being configured to particle diameter.The pyroconductivity of the vacuum insulation part 1 after the vacuum insulation part 1 and then having made present embodiment 1 is 1.8mW/ (mK).Afterwards, be 0.1mW/ (mK) by the increasing amount of pyroconductivity when the vacuum insulation part 1 of present embodiment 1 keeping 30 days under the environment of temperature 25 DEG C, relative moisture 60%.
Therefore, the vacuum insulation part 1 of 1 according to the present embodiment, by making the adsorption rate of the heat-conducting gas of the second sorbent 50 higher than the adsorption rate of the first sorbent 40, thus can obtain and pyroconductivity can be maintained lower vacuum insulation part 1 for a long time.
