Shanghai central air-conditioning installation location requirements

The installation location of the central air conditioner generally has the following requirements: Bedroom: The central air conditioner should be installed in the north-facing room or the east-facing room. Since the solar radiation in the northeast is very small, if there is only one wall in the south, sun visors should be installed. Coal stoves, gas stoves and heating equipment should not be installed. One is unsafe, and the other is conducive to the heat dissipation of the condenser. Activity room: A place not directly accessible to people. When the duct machine is blown down, the outlet and return air outlet must be at least 1 meter away. Outdoor unit: The outdoor main unit of the central air conditioner is larger than the ordinary split type air conditioner. Conditional users can install central air conditioning on special equipment, and users without professional equipment can also install the host outdoors. Pay attention to the location of the host. The ventilation and heat dissipation are good for easy maintenance and maintenance. The location of the host should be far away from many areas to avoid noise interference.

Living room: The central air-conditioning outlet cannot directly guide the main chair (three-seat sofa) in the living room too close to the crowd gathering area, otherwise it will cause headaches and other discomfort. When designing air conditioning ducts, it is necessary to use the outlet to one side of the sofa, so that the wind will come out from the side and the comfort will be higher. Kitchen and dining room: Keep the central air conditioner away from the kitchen as far as possible to avoid inhalation of smoke and dust, which will affect the air quality. If you need to install, there are two points to be careful not to blow directly on the hair dryer, blowing directly will cause the flame to fluctuate. 2. The outlet of the central air conditioner cannot face the workbench. Because the air inlet often attracts a lot of dust. If the restaurant’s air conditioner blows directly on the table, dust can enter the food with the wind and affect healthy eating. Shanghai air conditioning design

Shanghai central air conditioning cleaning

The harm of central air conditioning is not clean: because the air duct passes through the air outlet, the air outlet and the room, a relatively closed space is formed, and it is easy to live in a polluted air-conditioning environment for a long time. His nose was inflamed, his throat was itchy, his eyes were dry, he even had trouble breathing, headache, dizziness and chest tightness. In the air duct of the central air conditioner, there are various bacteria, microorganisms, fungi, dust mites, legionella, flu bacteria, etc. Through air conditioning, it can cause terrible infectious diseases. Since most of the air ducts are arranged in the roof of the building, the temperature and humidity in the air ducts are more suitable for the four seasons, so it often becomes a space for parasitic animals and insects (such as mice, chewing beetles, etc.). With the passage of time and the increase in the service life of the equipment, a large amount of dust (suspended particles) will adhere to the surface of the pipeline, which will cause the destruction of the boundary layer formed on the sidewall, that is, the laminar flow of the fluid in the pipeline. destroy. It also forms a turbulent phenomenon, increases internal friction, causes wind resistance, increases the load of the fan, reduces the capacity of the unit, reduces the service life of the drying equipment, and increases energy consumption.

Steps to clean up the central air-conditioning: sampling air duct: sampling the robot in the air duct, analyzing and determining the degree of pollution; providing users with an analysis report: whether there are obvious microorganisms in the air supply, and whether there are visible dust particles. When the ventilation system enters the room, a cleaning plan is formulated: the mechanism of the ventilation duct is analyzed, and a detailed set of plans is formulated according to the customer's requirements; a contract is signed: according to the analysis report, the cleaning plan, NE. Negotiate prices with customers and sign contracts; construction preparation: equipment and engineers stationed; on-site operation: operation of cleaning robots and use of high-power industrial vacuum cleaners to collect pipes. Disinfection: pipeline disinfection and ultraviolet treatment to avoid secondary pollution; cleaning effect inspection: visual inspection of cleaning effect; analysis report after cleaning: after cleaning, provide customers with an analysis report; compare with the acceptance value before cleaning; acceptance: "empty "The cleaning standard of the ventilation system is the national standard. Check the cleaning quality to ensure that the project quality meets the standard; on-site recovery: the re-installation of the tuyere will be re-assembled. Air volume adjustment.
