[0002] The airtightness of building rooms significantly impacts building energy consumption. Relevant research indicates that in heated buildings in northern my country, building energy consumption due to cold air infiltration accounts for approximately one-third to one-quarter of total building energy consumption. As the thermal insulation performance of building rooms continues to improve, the importance of airtightness becomes increasingly significant. Therefore, improving the airtightness of building rooms can significantly reduce building energy losses caused by cold air infiltration, which is of great significance for reducing building energy consumption. From a testing perspective, accurately measuring the airtightness of building rooms is particularly important for identifying leakage sources in building rooms and improving the overall airtightness of building rooms.

Therefore, there is an urgent need for a room pressure difference data processor that can dissipate heat to dissipate the heat generated by the use of the instrument, thereby avoiding damage to the electronic components inside the instrument and extending the service life of the instrument.

As the insulation performance of building rooms continues to improve, the importance of airtightness becomes increasingly significant. Therefore, improving the airtightness of building rooms can significantly reduce energy losses caused by cold air infiltration, playing a crucial role in reducing building energy consumption. From a testing perspective, how to accurately measure the airtightness of a building room is particularly important for troubleshooting leakage sources in the building room and improving the overall airtightness of the building room.
