Please note that pro yo! This treasure babe procurement for the central air-conditioning installation link, our services include Chengdu and surrounding counties, please see the following simple purchase before a certain few yo: First, please choose only friend purchase equipment directly photographed spot, the company is Gree authorized dealer, inventory stock, wholesale surrounding areas of central air conditioning installers, large individual can bargain! Second, the need to install the package, please choose to install a separate fee 1500 / station owners friends in Chengdu and surrounding areas note that already includes labor, materials, shipping, and so on. Third, the program needs to set the scene, please choose 500 deposit link. Many houses installation conditions are not so absolutely appropriate installation program needs to be adjusted, we can schedule a professional chef to your home given program. PS: I Taobao shop only take the amount of low-cost, offer the store will be slightly higher, if you go directly to our store, then you can contact customer service first reported a good price, and then provide the phone, since we can check the transaction in the store yo ~! To configure your own house air conditioning when you can refer to the following method (air conditioning cooling load calculation): [Living Room 180-230w / m] [Restaurant 200-230w / ㎡】 【bedroom 160-180w / m] [Office 180-200w / m] Calculation method: air conditioning cooling capacity / room area, such as: the bedroom area of ??12 square meters, can choose FG (R) 2.3/B1 cooling capacity of 2300W 1P, you can choose FG (R) 2.3/B1 2600 ÷ 12 ≈ 216w. / m, so to meet the cooling and heating effect of the (rough calculation based on this method, providing reference, consider the case when the actual configuration of housing insulation, orientation, floor height, glass, energy saving and other factors) to see if you still have no way to understand How to configure the air conditioner models, then you can directly contact our customer service oh ~ we will warm your service is not, they simply pick up the phone to play Ha: 18780123834! Gree central air conditioning construction process: First, the machine in place: The first step is to approach the construction team lifting the machine, pay attention to two points here as long as you can avoid subsequent problems. Distance from the roof of the machine may not be less than 1 cm, to avoid resonance with the top of the wall when the machine is running. Lifting the machine must be horizontal position, the installation requires special tools to measure, the machine is level. Second, the refrigerant copper installation: installing the machine to install the refrigerant tubes, which is Gree central air conditioning installation process is the most important aspect. All brass and solder joints should be welded manifold, there is no brass and copper welding. Must be charged with nitrogen (nitrogen welding process) during welding in a copper, copper tube inside which there is no air to avoid the generation of welding to the inner wall at the time the coking operation and into the compressor failure. After welding is completed with high-pressure nitrogen should soot blowing tube to keep the brass clean. Third, it is the pressure holding pressure nitrogen must be tested after completion of welding for copper, copper tube filled to a pressure of nitrogen gas packing, stress testing time is generally 24 hours. Of particular note: the use of R410 refrigerant, the need to keep the pressure tube 40 kg, R22 refrigerant is required to keep the tube pressure of 20 kg. Fourth, the installation of the condensate pipe: condensate pipe from the machine connected to the outdoors or a floor drain, keep at least> 1% slope. Installation of high quality from the indoor unit is connected to the nearest landing, finally together in conjunction with other condensate pipe or drain connected to the outdoors. Five out of the machine installation: do outside the machine fan outlet must be no obstruction in the rear 15 cm 50 cm inside and outside the machine, you must install all the landing foot damping block, to ensure normal operation outside the machine. Six vacuum and outside the machine is installed in front of the filling of refrigerant needed refrigerant pipe vacuum, the air inside the tube withdrawn, keeping the tube dry and free of moisture, otherwise the air and water with the refrigerant mixed to produce ice, can cause serious equipment damage. Specifications: After connecting the refrigerant pipes need to operate outside the machine; vacuum time is generally less than two hours and more online, a drag duct machine less than 20 minutes. Seven, filling refrigerant: After completion of the above work, you can open the refrigerant valve, releasing the go machine comes with refrigerant, the boot test and detect pressure, appropriate supplement until debugging is complete, to achieve the desired working condition immediately after. Eight outlet measuring installation: return air: usually return air will be installed together with the manhole, outlet size must be consistent with the machine back to the outlet, the situation can not be misplaced, so that it can achieve the best return air volume; and ensure adequate maintenance space. Nine, the signal line: signal line is not expensive, are generally used with a shield signal lines. This we can feel reassured. Installation specifications articles: Step 8 to install, step by step specifications need to have good material in place of light, there is no good construction process, it will also affect the use of air conditioning effect, air-conditioning equipment can be easily damaged. Each step must be careful.
