Central air conditioning is a kind of air conditioning usually installed in some large places, the installation of central air conditioning needs to involve a lot of equipment installation is more troublesome, a lot of big friends are not very understanding, the following small make up to explain to you.
Central air conditioning equipment installation process - specific process
1.? Inspection. Equipment arrives at the installation site first carefully check whether the outer packaging is intact, the model, the number is consistent with the design drawings, and then open the box to check whether the equipment itself is damaged;
2.? Placement line. According to the requirements of the design drawings and the building's axis or edge of the line delineation of the installation baseline;
3.? Positioning. According to the demarcation of the baseline positioning equipment installation position, the deviation should meet the requirements of the relevant regulations;
4. Leveling. Easy to vibrate the base of the equipment to be placed on the thickness of the vibration damping pads, leveling test position if the technical documents are not specified, can support the sliding parts guiding surface, protection of rotating parts guiding surface or axis, etc. as a reference reference benchmark;
5.? Fixed. Heavy equipment or vibration equipment need to be fixed, foot bolt in the hole should be vertical without tilting, and the distance from the hole wall should be more than 15mm and should not touch the bottom of the hole, the length of the bolt nut exposure is about 1/3 to 2/3 of the diameter of the bolt, the concrete in the hole of the foot bolt to reach the design strength of 75% or more before tightening the foot bolt;
6.? Cleaning. For equipment with cleaning requirements, cleaning should be carried out in accordance with the relevant provisions of the "General Specification for Construction and Acceptance of Mechanical Equipment Installation Projects", and the use of metal and other sharp instruments to scrape the surface of the equipment is strictly prohibited;
7.? Marking. After each installation of a piece of equipment, should be in the operating surface marking equipment bit number, equipment bit number to be consistent with the equipment table, flow chart, equipment layout diagram in the bit number.
Central Air Conditioning Installation Precautions
1. Outdoor unit discharged heat should have no effect on the neighbors;
2. Positioned around if there is a strong source of heat and other equipment exhaust vents, vapors and combustible gases, it should be adjusted in a timely manner to contact;
3. Outdoor unit should be installed in a Well-ventilated location, if there is a short-circuit situation, the installation should take measures to solve;
4. Outdoor unit in the installation of the location of the operation of the noise on the neighbors should be less than the national noise standard: daytime: 55dB (A), morning and evening: 50dB (A), late at night: 45dB (A)
5. Outdoor unit? Front side needs 500mm maintenance operation space;
6. Outside the machine as far as possible away from people on the first floor bedroom, living room, but also to consider away from the second floor bedroom, study;
7. Intake side (back side) with obstacles distance: more than 300mm; both sides (left and right side) with obstacles distance: more than 150mm; the front side of the obstacles distance: more than 500mm; the side of the machine with the machine distance: more than 100mm; the top side of the obstacle distance: more than 1000mm.
In the above small and medium-sized editor very detailed for you to explain the installation process of the central air-conditioning and central air-conditioning installation precautions, to help you better understand some of the knowledge of the central air-conditioning installation. In the daily use of the central air conditioning should pay attention to the regular cleaning and maintenance of the central air conditioning, to maintain the operation of the air conditioning, to extend the service life of the central air conditioning.
