IV. the ventilation and air-conditioning engineering construction quality approval standard "GB50243-20024.2.3 fire protection duct of ontology, frame and fixed material, gasket material must be non-combustible materials, the fire resistance rating should meet the design requirements. 4.2.4 composite duct of cladding materials must be non-combustible materials, internal thermal insulation should be non-combustible or nonflammable B1 level and harmless material. 5.2.4 explosion-proof air valve fabrication materials must meet the design requirements, not to replace. 5.2.7 smoke control system for flexible short-tube production materials must be non-combustible materials. 6.2.1 the duct passes through closed fire, explosion-proof wall or floor, you should set the embedded tube or protective casing, the plate thickness should not be less than 1.6 mm. Air ducts and protection casing, the application does not burn and the human body without harm of flexible material block. 6.2.2 duct installation must meet the following requirements: 1 wind tube no other pipeline crossing; 2 conveying contains flammable, explosive gases or installed in flammable, explosive environment air duct system should have a good grounding, by living area or other auxiliary production room must be tight and may not be set interface. 3 outdoor fixed cable riser is strictly forbidden in the lightning rod or lightning network. 6.2.3 conveying air temperature is higher than 80 degrees centigrade of air duct, should follow the design provides for the adoption of protective measures. 7.2.2 fan gear exposed parts as well as through the atmosphere into, export, you must install Shield (network) or to take other security facilities. 7.2.7 electrostatic air filters metal shell grounding must be good. 7.2.8 electric heater installation must meet the following requirements: 1, heater and the steel frame of the insulation must be non-combustible material; Terminal exposed should additional security shield; 2, electric heater metal shell grounding must be good; 3, connect the electric heater of wind pipe flange gasket, heat-resistant non-combustible materials should be used. 8.2.6 fuel pipeline system you have to set reliable anti-static grounding, the pipe flange should use galvanized bolted or flange Department with copper conductors with a cross-over, and engage in good shape. 8.2.7 gas system piping and unit connection may not use the non-metallic flexible hoses. Gas pipeline blowing and pressure testing should be a compressed air or nitrogen, water use is strictly prohibited. When the gas supply pipe pressure greater than 0.005Mpa, weld of non-destructive testing of the implementation of standards should be designed. When designing not require using ultrasonic flaw detection should be paid to quality is not lower than class ⅱ. 11.2.1, ventilation and air conditioning system installed, you must be a system of measurement and adjustment (debugging). System debug should include the following items. 1, equipment commissioning and debug single; 2, the system has no production load of combined trial running and debugging. 11.2.4 smoke joint commissioning and adjustment of results (air flow and pressure), must meet the design requirements of the fire. Fifth, the "people's basement design code GB50038 20053.6.6 diesel power station-storage room should meet the following requirements: 1 storage room to separate the layout and the engine room; 2 petrol storage room should be set out on the open fire door, its bottom surface should be connected to the room (or walk) ground or supposes 150-200mm threshold; 3 non-diesel engine exhaust pipe, air duct, wires, cables, etc. through the oil companies. 5.2.16 the filter design selection, the absorber is strictly less than the rated air flow through the filter of the air volume of absorber. 5.3.3 basement peacetime and wartime combined with a ventilation system should be normal and wartime conditions respectively new air flow calculation system, and press the following selection of ventilation and protection devices. 1, according to the largest selection of new air clean air duct diameter, coarse filter, sealed devices such as valves and Fan; 2, according to the calculation of the wartime clean ventilation air selects gantry explosion-proof wave valve, and the door leaf is opened in peacetime to check ventilation rate; 3, press the wartime filtrate ventilation of ventilation rate selection of filtrate into the (row) wind pipeline filter absorber, filter-free filtrate vent fan, and the closed valve. 5.4.1 introduction of basement of heating pipes, through the Department of Defense envelope should take the reliable protection measures, and should be closed in the inner side of the envelope settings work pressure of not less than 1.0MPa valve. 6.2.6 in the basement of the cleaning area, each protection unit shall set the living water, drinking water cistern (carton). The cistern (box) of effective volume should be under wartime masking basement number, wartime water standards and water storage time calculation determined. 6.2.13 basement water supply pipe on protection valve settings and installation should meet the following requirements: 1 when the water supply pipeline from the entrance into the inside of the closed door protection; when introducing from civil defense wall, in the inside of the air defence of envelope; through protection unit is set between the protective sealed partition when the protective seal wall set on either side of the pipeline; 2 protection valve of nominal pressure should not be less than 1.0MPa; 3 protective valves should be used for spool stainless steel or copper material of gate valves or valve; 6.5.9 diesel generator room of oil when introducing from importers, should be set within the closed door protective oil valve; the introduction from the envelopes, the inside of the wall should be at or roof inside set oil valve, which shall be not less than the nominal pressure, the valve 1.0Mpa should be set up in the easy-to-use, and there should be clear and close flag. Outdoor place should be set and basement resistance levels the same tubing connectors well. 6. the residential design code GB50096-1999 (2003 Edition) 6.2.2 setting centralized heating system of houses of indoor heating calculation temperature should not be lower than sheet 6.2.2 requirements. Table 6.2.2 indoor heating calculation temperature room temperature (℃) bedroom, living room (Hall) and toilet set 18 kitchen 15 heating of the staircase and corridors 14 Note: have a bath and have centralized hot water supply system in the bathroom, the design should be as 25¡æ. 6.2.4 centralized heating system for overall adjustment and maintenance of facilities, should not be set to set. 6.4.1 kitchen range hoods, exhaust pipe through the wall directly to outdoor, outdoor vent settings Typhoon andPrevent pollution of the environment of the widget. When the hoods of the exhaust pipe flows into the vertical ventilation duct, vertical ventilation road section should be based on the determination of the exhaust volume calculations, should take the tube without return, shaft without leakage. 6.4.3 no external Windows in the toilet, you should set a backflow of exhaust ventilation duct, and set aside for exhaust mounting location and condition of machinery. 6.4.5 hottest temperatures higher than average outdoor and equal to 25 ° c, each residence should be reserved for the installation of air-conditioning equipment for the location and condition.
