Shanghai GEA room air conditioning repair maintenance

1.1 arc-shaped high-strength door GEA Denco unique arc-shaped front panel design, enhances the strength of the panel. Lined with "0" flame retardant rubber silencer insulation materials. Material density: 75kg / m3, play a good thermal insulation and noise performance. Tender: Precision air conditioning unit panel has sufficient mechanical strength to be using curved structure (precision air conditioning unit panel should adopt special shape structure, enhance its mechanical strength). Panel should be lined muffler insulation materials, meet fire safety standards to prevent surface condensation unit. 1.2 Front Panel Real-Time Analog filter fouling indicator (optional) This is a unique GEA. On the unit door is equipped with filter fouling gauge and intuitive real-time status display filter is clogged. Maintenance personnel observed an excessively dirty filter blocking state, plan ahead filter replacement maintenance work, rather than wait until the filter alarm. Remaining air conditioner manufacturers, such as Stulz, Emerson and so does not have this feature. Tender: precision air conditioning unit installed on the door of the filter fouling indication meter, you can visually display real-time filter clogging state. So that maintenance personnel observing strainer fouling state, advance preparation for filter replacement maintenance. 1.3 The role of central air-conditioning system heat exchanger manufacturing technology is the indoor enclosed areas where heat removal, to the outdoor heat into the outdoor air environment. In precision air conditioning indoor unit, the heat of the indoor return air through the coil and cooling medium for heat exchange, the outdoor unit heat exchanger coil for refrigeration media and outdoor air heat exchange, next to the heat exchanger is the core component of the air conditioning system. GEA global leader in heat exchanger coil and plate heat exchanger professional design capability and production technology. 1922 GEA invented the elliptical finned tube. Finned tube heat exchanger in the pipeline cross-section into an oval, elliptical tubes longer consistent with its direction and air flow direction. Increase the heat transfer area. An identical cross-section of the pipe, circular finned tube heat ratio is 30% higher. Oval tube windward circular cross-sectional area are more small, to reduce air resistance and turbulence phenomena, the air-side resistance than a round finned tubes 50 percent smaller, can effectively reduce the fan operating costs. Also oval tube is not dead round tube produced to facilitate routine cleaning and maintenance. GEA With 90 years of rich experience in the design and manufacture of heat exchangers, has become a leader in the field of air cooling system products. Depending on the working conditions, GEA optimized design unique pieces to form the best type of duct, and selection of an efficient heat transfer material, so as to maximize the air and improve heat transfer efficiency refrigerant, to save energy. GEA Industrial Heat Exchanger Division in Wuhu production base was established in 1995, the coil portion has a variety of models of high-speed stamping machine and Stulz is Wuxi Italian Luvata production, part of Jiangsu often made refrigeration available. Tender: Precision air-conditioning factory should employ independent technical design and manufacture of heat exchanger coil (cooler), it has a unique duct design to improve heat transfer efficiency, to save energy. 1.4 coolers special structure preventing water bleaching phenomenon in order to improve the heat exchange efficiency, cooler fins without the hydrophilic coating, while in the middle of the table and floor installation cooler condensate collection tank. In the middle of interception cooler condensate, in order to avoid the condensation of water droplets flow cooler lower part of the larger, not yet reached before the condensate collection tank is the amount of wind blown into the room air flow with the air. Stulz coil middle of no condensate collection tank. Some models use coil hydrophilic coating, scoop water problems have occurred. Tender: In order to improve the heat exchange efficiency, precision air conditioning cooler fins without the hydrophilic coating, while in the middle and the bottom plate coolers are mounted condensate collection tank. In the middle of interception cooler condensate, in order to avoid the phenomenon of bleaching water cooler occur and affect the safe operation of the equipment room. 1.5 large area of ??low resistance "W" shaped air filter uses a metal frame, front and rear sides installation of metal mesh, sandwiched inside two layers of metal mesh filter cotton, was "W" shape. Increasing the filtration area, reducing drag on the air side, reducing fan energy. Increasing the filtration area extends the filter is clogged clean-up time, reduce maintenance work. Filters can be cleaned or replaced filter cotton. Most domestic air-conditioning manufacturers, because of cost, only the use of filtering surface tile, rather than "W" shape. Stulz German production of air-conditioning is a paper of "W" filter. Tender: precision air conditioning filter should be used a metal frame, front and rear sides sandwiched inside the metal mesh filter cotton, was "W" shape. Increasing the filtration area, reducing drag on the air side, reducing fan energy. Increasing the filtration area extends the filter is clogged clean-up time, reduce maintenance work. Filters can be cleaned or replaced filter cotton. 1.6 Carel electrode humidifier electrode humidifier infrared humidifier significant comparative advantages:.. A humidifier electrode than the infrared energy-saving 15-20% b infrared humidifier is open, the scale will be filled with air in the entire room , thus affecting the reliable operation of the server c. open the infrared humidifier, the water and room air contact, easy breeding bacteria, the engine room operator health hazards, so infrared humidifier is banned in Europe. Only Emerson eliminated the use of foreign infrared humidifier to buy as features. Its emphasis is not affected by the water quality, the humidifier may alarm a little, but the consequences resulting humidified open but affect reliable operation of the equipment room. Tender: precision air-conditioning should be energy-efficient electrode humidifier. Humidifier tank seal will prevent scale in the entire room filled with air, thus affecting the reliable operation of the server, and avoid contact with water and air propagation of bacteria, affecting the engine room operator health hazard.
