Central air conditioning water system installation process and use

Central air conditioning water system installation process and use, okmarts.com. The central air-conditioning water system is a relatively complex system. Before installation, make preparations in advance, including drawing review, start-up report, technical disclosure, project construction, self-inspection, self-inspection, partial project acceptance, data sorting, etc. . After all the preparations are completed, the construction can be officially started. The following are the main installation procedures of the central air-conditioning water system:

　　 One, fan coil installation

　　 1. Installation process

Open the box and check whether the accompanying documents, spare parts, and accessories are installed properly, determine the location and size of the indoor unit, and the position of the boom; prepare the auxiliary materials needed for construction, such as screw rods, nuts, gaskets, canvas, iron strips, dovetail wires, etc. ; Prepare the tools needed for construction, such as scaffolding, ladders, adjustable wrenches, hand hammers, electric hammers, fork wrenches, cutters, saw blades, tape measures, markers, etc.

　　2. Installation specifications

　　The fan coil unit should be handled with care during the installation process to ensure that the fan, coil unit, casing, insulation layer, etc. are intact. The distance between the roof and the coil should not be less than 30mm. All indoor hoisting should be equipped with a return air box to avoid affecting the use effect. The inlet, return, and drain pipe joints should be sealed, the pipeline must be insulated, the coil air outlet connection needs to be soft, the interface should be firm and tight, and the condensate pan should be cleaned after the fan coil is installed.

　　 After the installation of the fan coil is completed, gently rotate the fan impeller to check whether there is friction. After the pressure test of the water system is completed, the fan coil should be protected in time for the finished product, and at the same time, beware of the stolen goods falling into the tray and blocking the condensate pipe.

　　 2. Pipeline installation

　　 1. Installation process

Determine the direction of the pipeline and set the line according to the installation drawings, drill the holes with an electric hammer and install the supports and hangers; remove the rust and anti-corrosion treatment on the pipeline and connect it with the fan. After all the pipelines are installed, perform the pipeline pressure test, and then The pipeline is insulated.

The pipe insulation material of the central air-conditioning water system should be made of rubber-plastic insulation materials with good waterproof effect, good flexibility, fire resistance and flame retardancy. During the specific construction, attention should be paid to keeping the surface of the insulation material clean and free from stretching. Wrap it up with matching tape to make sure there are no cracks. If you need to cut the insulation pipe and install it, you can turn the cut surface toward the inside, and stick the cut part firmly with special glue.

　　 2. Installation specifications

　　The inlet and outlet of the main engine, water pump, fan coil and other pipes of the water system should be equipped with damping soft joints; an exhaust valve should be installed at the highest point, and a manual drain valve should be installed at the lowest point. The condensate pipe should maintain a certain slope to ensure that the condensate drains smoothly. After completion, the water flow experiment can be done. In addition, pipelines with cold insulation requirements should be padded with anticorrosive wood shingles between the support and the pipeline to prevent "cold bridges" when the pipeline is in use.

　　 The suction port of the water pump should be equipped with a filter. Considering the convenience of disassembly and cleaning, the water supplement system can be connected to the system return pipe. The installation of the pipe support bracket should be in close contact with the pipe and firm fixation.

　　When the indoor unit condensate system is filled with water, the condensate pan can be filled with water. If the water can be drained smoothly and the condensate pipe interface does not seep, the installation is successful.

　　 Three, cooling tower installation

　　 1. The load bearing, environmental conditions and the size of the installation space should be considered during the installation process, and sufficient heat exchange space should be ensured after the installation of the system to ensure the normal operation of the system. The cooling tower should be installed horizontally, and the allowable deviation of the horizontal and verticality of a single cooling tower is two thousandths.

　　 2. The direction and position of the water outlet and nozzle of the cooling tower should be correct, and the water distributor should distribute water evenly. The radial clearance between the end of the fan blade and the tower body should be uniform, and the blade angle should be consistent.

　　 4. Water pump and auxiliary equipment installation

　　1. The allowable deviation of the pump's plane position and elevation is ±10mm, and the installed anchor bolts should be vertical, tightened, and in close contact with the equipment base to reduce noise during operation.

　　2. The horn sets are placed correctly, steadily, and in close contact. Each set does not exceed 3 pieces.

　　3. The connection between the shock absorber and the pump foundation is firm and stable, and the foundation is tight.

　　 5. Computer room electrical installation

　　 1. Choose the cable model according to the machine (main machine, water pump, cooling tower and other auxiliary equipment), and the main machine power must be controlled by an independent air switch.

2. The wires in the conduit are not allowed to have joints, nor are they allowed to penetrate the wires that are wrapped to restore insulation after the insulation is broken. If the power cord is not long enough, a wire box should be installed at the joint; wires of different voltages and different circuits must not be worn In the same line pipe.

　　 3. The pipeline layout should be horizontal and vertical. If the pipeline is installed in the wall, the groove depth should be greater than the diameter of the line pipe, and the pipeline should be fixed with iron nails and then cement mortar after installation.

　　 Six, tuyere installation

　　1. Before installing the air outlet of the central air-conditioning water system, the connection between the indoor unit and the opening on the decorative surface of the air supply and return air outlets should be tightly sealed to avoid insufficient air flow and affect the use effect.

　　 2. The installation height of the same air outlets in the same hall or room should be the same, and the arrangement should be neat. When installing, ensure that the horizontal and vertical are horizontal and vertical, and the frame is close to the decorative surface of the building without obvious gaps.

　　3. The switch installation should be aligned with other switches on the side. If the size is inconsistent, the bottom line should be aligned.

The main installation process of the central air-conditioning water system. Because the water system involves many problems, the installation of the water system cannot be separated from the strict operation of the technicians and the cooperation of various installation auxiliary materials. Only multi-party cooperation and multi-pronged To achieve the best use effect
