A waste exhaust ventilation door automatic control device comprises a core body (), an inner door body () and an outer door body (); wherein the core body is fixed on a ventilation opening of the waste exhaust ventilation door, a top of the outer door body is movably hinged on an outer side of the core body, and a bottom of the inner door body is movably hinged on an inner side of the core body; when there is no pressure fluctuation outside the core body, the outer door body and inner door body will open, and when there is pressure fluctuation outside the core body, the outer door body and/or the inner door body will be closed automatically due to a pressure difference between inside and outside the core body. A vehicle body comprising the waste exhaust ventilation door automatic control device is also provided.

A phase-change energy storage air duct of an automobile air conditioning system. A phase-change energy storage unit () is configured inside an air duct () of an air conditioning system. By means of phase-change heat absorption or release, residual heat in the air is absorbed, and the heat is released to air with a lower temperature, so that energy is recycled to achieve energy saving. The temperature of air entering a room or a carriage is kept stable, and thus the user experience is improved. When the air conditioning system fails, the phase-change energy storage unit () can still utilize stored cooling capacity or heat to cool down or heat up air in the air duct, so that a supply of air can be kept stable for a period of time, and thus the user experience is improved. The present application also relates to an automobile air conditioning system.

An absorption-induction convectional dust-controlling/removing air/fog curtain device of a fully-mechanized working face and a method thereof, wherein the device includes an extraction type dust-purifying blower, a sector deflector, a shearer external spraying device and an inter-hydraulic-support spraying device. The shearer external spraying devices are mounted at both sides of a shearer body close to rocking arms of a shearer and the inter-hydraulic-support spraying devices are mounted at two un-advanced hydraulic supports and two hydraulic supports at a leeward side of a front drum of the shearer respectively. Two extraction type dust-purifying blowers symmetrically mounted at the rocking arm close to the body of the shearer are started simultaneously with their air inlets exactly facing front and rear drums of the shearer respectively, and air outlets connected with the sector deflector. With the device and the method, the working environment is improved and safe production of the coal mine is guaranteed.
