[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - Pipeline Project] duct installed in place according to the site, can be connected into a length on the ground, with the lifting of the method in place, you can lookout tube a section of land on the bracket, section by section connections. General order is the first dry pipe, after the branch pipe. Riser installation is usually installed from the bottom up. Post-installation leveling position, alignment, designed to meet the requirements specified. Duct installation should be noted: 1, when the duct using flangeless connection, the interface should be tight and firm. The four corners of the rectangular duct positioning and sealing arrangements must be applied. Duct connecting the two planes should be straight, not misplaced and distorted. 2, mounted on a bracket round wind pipe bracket should be located. 3, the wind piercing the roof should be set outside the rain cover. 4, easy to produce condensate transport duct, the slope of the design requirements should be installed. Can not have a vertical duct bottom seams, if seams sealed applications. 5, steel duct with brick, concrete duct connectors should conform airflow direction, wind pipe and duct joint surface must be sealed. 6, the branch duct insulation, hangers should be located in the outer insulation, and not damage the insulation. 7, air hose and a vertical mains plug, the interface should be set wind adjustment. After the air duct tightness test tube installed, the system pressure should be closely rating test, air leakage should be in line with national norms "Ventilation and Air Conditioning Engineering Construction Quality Acceptance" tightness test should GB50243 the requirements, the system meets GB50243 specification appendix leaked assay and amount of air leakage testing. Tightness test should be low pressure system uses sampling, the sampling rate of 5% and less than one sampling system. When processing and leaked test failed, the sampling rate should be required to do the amount of air leakage test. Tightness test medium voltage systems, should be under strict eligibility leaked detection of air leakage duct system for sampling, the sampling rate of 20 percent engineering, and less than one sampling system. High-pressure system should be fully carried out air leakage test. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - decontamination] decontamination of air purification air purification engineering program ● air cleanliness levels of purification, shall be used for the early effect, in effect, HEPA filter three filters. 100,000 air purification, can be sub-generation high-efficiency air filter air filters. ● air filter arrangement and selection of installation shall comply with: the early efficiency air filters should not be the choice of oil-soaked filter; efficiency air filters should be set up to focus on purifying the air conditioning system of positive segment; HEPA filter or sub-efficiency air filters should be set at the end of purifying the air conditioning system, high efficiency air filter installation should be simple, reliable, leak and should be replaced; in effect, sub-efficient, high efficiency air filters should be chosen according to the rated wind; resistance, efficiency similar to the HEPA filter should be set at the same purification workshop. ● determining the centralized or decentralized clean air-conditioning system, should be considered the characteristics of the production process and clean room air cleanliness level, area, location and other factors. Where the production process of continuous, clean room or clean room area is large, centralized location and noise control and vibration control demanding clean room ventilation pipeline project, should adopt a centralized air conditioning system purification. ● To clean up the air conditioning system of electric heating, you should choose a tubular electric heater, the position should be arranged in the HEPA filter upwind side of the refrigeration room works, and should have fire safety measures. ● blower selection works offer total air volume air conditioning system and the total resistance value can be cleaned twice early in the calculation efficiency, high efficiency air filters should drag their resistance. ● decontamination clean air conditioning system in addition to the DC systems and set-duty blower system, should be taken to prevent outdoor air pollution through incorporation of new air purifier anti irrigation measures fall within the workshop. ● When the air conditioning system should be designed to purify the rational use of the return air, where the process produces large amounts of harmful substances and local processing can not meet the health requirements, or other hazardous process is not applied back to the wind.
