The so-called positive pressure of the pressure delivery outlet pressure is what? Pressure delivery outlet generally used as outlet, but also directly with the fan coil supporting use of customized pressure delivery outlet, widely used in gathering complete air conditioning system, you can also adjust the leafy off valve to adjust the air flow. By now, most people worry than the fire of doubt, specializing in the production pressure delivery outlet, 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 is the maximum pressure value of general human full of fire doors in a closed state to allow the fire doors can open both ends and on the maximum allowable pressure values, national values ??are not completely together, positive pressure outlet, most countries have put 50Pa as the maximum allowable pressure. The so-called minimum pressure value refers lax fire personnel. Once the fire door open, and open the door to the stairwell before the pressure chamber of the instantaneous drop, pressure delivery outlet sales, 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 of the Settings tab: In the front room fire elevators do not have the natural draft conditions, it should set up an independent pressurized air supply smoke facilities. Stairwell and the front room where the site does not have a natural draft conditions at the right time, do not have the parts should be set independently pressurized air supply system. Scissors stairwell mechanical pressure air supply by two staircases wind calculations outlet should be set separately. When pressurized air supply and smoke, the positive pressure value notes stairwell 40 to 50Pa; preceding type pressurized air and smoke, the positive pressure of 25 to 30Pa walkway value 0 or negative pressure. Stairwell should be provided every two to three a pressurized outlet; the front chamber should be located on each floor of a pressurized outlet. Pressurized air supply and mechanical exhaust wind speed metal duct at the right time, can not be greater than 20m / s; using a smooth inner surface of the concrete and so on nonmetallic duct at the right time, can not be greater than 15m / s mechanical pressure. Winds blowing outlet should not exceed 7m / s Suntown clean air conditioning (Figure) |. pressure delivery outlet Order | pressure delivery outlet provided by the Texas Air Conditioning Equipment Co., Ltd.
