つている。 A conventional laboratory of this kind is the one shown in Japanese Patent Publication No. 7822/1983. In such laboratories, experiments that are likely to generate infectious aerosols are conducted using a safety cabinet installed within the laboratory, but conventional ones are equipped with advanced physical containment equipment P-3 (National Institute of Health Sciences Pathogen Safety Cabinet). Therefore, the exhaust gas from the safety cabinet is configured to be circulated within the laboratory.

イパスできるようにしておくのが好ましい。 However, in cases where the use of a B-type safety cabinet with a Hepafilter is required to comply with P-3 above, the exhaust from the safety cabinet must be vented outside the laboratory, and the temperature within the laboratory must be maintained at an appropriate temperature at all times. . For this reason, an intake system and an exhaust system were installed for the laboratory, and the exhaust volume was greater than the intake volume to maintain negative pressure in the laboratory at all times.
It is known that an air conditioner is installed in a laboratory, a heat exchanger is connected to the intake system and the exhaust system, and the air passing through the intake system and exhaust system is exchanged with each other by the heat exchanger. . However, in this type of heat exchanger, if dangerous substances adhere to the inside of the heat exchanger, it is extremely troublesome to remove them, and in particular, during formalin fumigation, formalin adheres to this area and has the disadvantage that it is difficult to remove it. Therefore, it is preferable to be able to bypass the heat exchanger when the heat exchanger is not required or when formalin fumigation is being performed.
