What should I pay attention to when installing indoor central air conditioning?

What should I pay attention to when installing indoor central air conditioning? It depends on whether your central air conditioner is a water machine or a fluorine machine. If your central air conditioner is a water machine 1, pay attention to the hot melt between PPR pipe joints to prevent water leakage, use insulation pipes with sufficient thickness to keep warm, and do a good job of maintaining pressure after the pipes leave. 2. Whether the power supply and voltage in your home meet the requirements of the air conditioning equipment provided, confirm the indoor and outdoor models and ensure the correct installation. The power and signal wires of the air conditioner must be wired according to the requirements of the equipment. 3. Confirm whether the installation positions of indoor and outdoor units of central air conditioner, the direction of connecting pipes between indoor and outdoor units and the drainage position of condensate pipes are reasonable. It is required that the connecting pipes of internal and external machines are horizontal, flat and firm, and the heat preservation treatment is complete. If your central air conditioner is a fluorine machine, please refer to the construction requirements of Jingfeng HVAC 1. The indoor unit must be hung horizontally, and the air inlet and outlet should be treated with tape, cardboard and other things to prevent dust. Glue and rivets should be used to connect the air outlet with the indoor unit, and the soft belt of the air outlet should be riveted, which must be insulated. (The length of the soft belt should not exceed 25cm, if it exceeds the air duct. 2. Installation of copper tube 65438+. The spacing between supports shall not exceed 1m, and must be horizontal, flat and firm. Copper pipes and thermal insulation must be fixed on the supports. 2> Before installation and welding, be sure to carefully check whether there is dust or other things inside and outside the copper tube. The welding of 3> copper tube must be protected by nitrogen, and the welding should be tight without bubbles, and covered electrode cannot flow into the copper tube. (No cooling with water) 4> Before maintaining the pressure of the copper tube, the inner wall of the copper tube should be flushed with nitrogen to remove dust. 5> The pressure of the copper tube is kept at 40kg until the main engine is installed. 3. Installation of thermal insulation layer1>; The interface of thermal insulation materials must be bonded with glue to prevent future openings. When the internal machine is connected to the copper pipe, the internal part should be wrapped before the external heat preservation. 2> Copper tube is a lintel, and the copper tube with holes can't be kept well, so it must be filled with foaming agent. 3 >; Pipeline insulation must be handled correctly. 4. 1 >; The bracket of condensate pipe must be replaced separately, and the slope of all pipes shall not be lower than 1% (horizontal pipes are strictly prohibited). 2 >; A ball valve should be installed at the junction of condensed water and internal machine. 3> After the condensate water is installed, the running water test must be carried out.
