The so-called positive pressure of the pressure delivery outlet pressure is what? Pressure delivery outlet generally used as outlet, but also directly supporting the use of fan coil, fire pressure delivery outlet, widely used in gathering complete air conditioning system, you can also adjust the leafy off valve, positive pressure before delivery outlet Face to adjust the air flow. By now, the most worrying question than the fire, the fire is built with the needs of modern, high-rise fireproof construction demand will be higher. Pressure delivery outlet fire function how? Whether domestic or foreign fire safety regulations, it has pressurized with demand, which should make in a fire, stairwell pressure> antechamber pressure> hallway or room pressure. The so-called positive pressure of the pressure delivery outlet, means the pressure difference across the fire door stairwell fire doors, the front room and the corridor between. The degree of positive pressure can be divided into a maximum allowable pressure value and the minimum pressure value. The so-called maximum allowable pressure value refers to all fire doors allow fire doors at both ends in a closed state of general human values ??can push the maximum pressure on the value of the maximum allowable pressure, pressure delivery outlet, countries not to be taken completely together, most countries have put 50Pa as the maximum allowable pressure. The so-called minimum pressure value, electric pressure delivery outlet, means fire personnel lax. Once the fire door open, and open the door to the stairwell before the pressure chamber of the instantaneous drop, in order to avoid smoke intrusion, should adhere to the doorway at a certain wind speed should have minimal blowback pressure difference. Minimum differential pressure value (or minimum doorway wind speed) on fire and smoke requirements, countries have different rules and requirements. Outlet pressure and the exhaust outlet of the exhaust using tags: smoke and part of the smoke exhaust facilities: room with smoke in the stairwell, stairwell front room, fire elevator room, smoke stairs former combined fire elevator room, closed the refuge floor (rooms) and other parts of the evacuation and the evacuation outlet pressure fan sent by air to the pressurized air pressure is higher than the aisle and the room, smoke is not invasive; or through openable smoke outside the window or the window in time to drain away the smoke; help evacuation, called smoke. Smoke: walkways, patios, and so part of the room and through a multi-leaf smoke machine smoke excluded; or through that open window to the outside window or exhaust fumes to drain away in time; to facilitate the evacuation, also called smoke . So the exhaust into mechanical exhaust and can be opened outside the window natural ventilation pressure delivery outlet, fire pressure delivery outlet, Sheng clean air-conditioning (high merchant) provided by the Texas Air Conditioning Equipment Co., Ltd.
