Flow chart of installation specification and requirements of central air conditioning system (do maintenance personnel need college major)

Central air conditioning has gradually become the standard of household air conditioning. Many families usually regard central air conditioning as the first reference of air conditioning equipment when designing decoration schemes. However, the central air conditioner is a semi-finished product, and it needs to be installed up to standard to produce corresponding effects. There are two sayings circulating in the central air-conditioning industry: quot 10 product 10 installation = 100 comfort experience quot and quot, three-point product and seven-point installation quot, which shows how important it is for central air-conditioning to do a good job in construction and installation!

The installation of central air conditioning is mainly divided into four parts: outdoor unit installation, indoor unit installation, piping system installation and control system installation. Each installation link affects the use of air conditioners and the service life of equipment, so it is very important to standardize the installation of each link. Among them, the installation of indoor unit of air conditioner must conform to the 3-2 criterion, otherwise it will easily affect the installation progress and later use effect of central air conditioner. So what is the 3 2 criterion? Can be summarized as: three important rules and three no rules.

Three main standards for indoor unit installation

1. Indoor equipment of central air conditioner should be installed horizontally.

The indoor unit of central air conditioner is installed in the ceiling, and it is difficult to deal with the problem of abnormal use or failure due to irregular installation. The indoor unit of the central air conditioner is equipped with a water collecting tray to collect condensed water and discharge it uniformly. If the indoor unit is not installed horizontally, it is easy to cause condensation water accumulation. The environment of condensed water is easy to breed bacteria, molds, fungi and other microorganisms. After a long time, it will produce odor, seriously corrode the water storage tray, cause water leakage, and affect the health of air conditioning. In addition, if it is not installed horizontally, the indoor room of the air conditioner will be in an inclined state, and the internal fan will also be inclined, which will cause great noise when rotating, and will also wear the support rod of the fan motor, thus shortening the service life of the equipment.

2. The drainage hose inside the central air conditioner should be installed horizontally.

The drainage pipe of the indoor unit of the central air conditioner is installed on the side. When connecting the condensate pipe, make sure that the hose at the connecting pipe is installed straight. If the hose is not installed straight, it is easy to make the diameter of the drain pipe smaller in the folded state, which is not conducive to drainage and easy to accumulate water, thus affecting the use of central air conditioning.

3. Dust-proof measures should be taken for the air outlet and air return of the central air conditioner.

The installation of central air conditioning is generally in the early stage of decoration, the most common situation is the synchronization of water and electricity, followed by carpentry, bricklayer, bricklayer and other decoration stages. Other types of work are prone to produce a lot of dust or dust during construction. If the indoor unit with central air conditioning is installed, the air outlet and air return of the indoor unit are not closed in time, and the dust, dust and small particle garbage generated in the process of indoor decoration can easily enter the indoor unit, which will affect the cleanliness of the indoor unit and the health of the central air conditioning.

Two prohibition standards for indoor unit installation

1. Do not install the indoor unit of central air conditioner near the floor.

The indoor unit of central air conditioning needs to be fixed on the floor, and the fan in the indoor unit rotates, which will produce vibration when it runs. If the indoor unit of air conditioner is installed near the floor, the vibration of the equipment will resonate with the floor, produce noise and even affect the users upstairs. Therefore, when installing the indoor unit, the distance between the indoor unit and the floor should be regarded as a key point of acceptance. The indoor unit should not be fixed on the floor directly with screws, but with screws. The screws on the floor should be made longer, so that there is a certain space between the indoor unit and the floor, thus reducing the noise.

2. Do not use a nut to fix scr.

The indoor unit of central air conditioning needs to be fixed on the floor with screws, and the screws and indoor units are fixed with nuts. If the screw is fixed with a single nut, with the long-term operation and vibration of the central air conditioner, the nut of the indoor unit fixed on the screw will gradually slide down, thus affecting the stability of the indoor unit. Therefore, double nuts must be used to fix the indoor unit on the screw to increase the firmness and stability of the indoor unit. Some indoor units are installed in special locations and need to use long screws. At this time, due to the long length from the screw to the indoor unit, the indoor unit is prone to shake during operation, which affects the stability of the indoor unit and even produces noise. In this case, it is necessary to fix the screw with angle steel to increase the stability of the screw, reduce the shaking of the indoor unit and reduce the noise.

abstract

Central air conditioning is a finished product when installed together, and the effect of air conditioning can only be exerted by standard installation. Therefore, the installation of central air conditioning can not be separated from professional and standardized installation. When purchasing central air-conditioning, we should also examine the professionalism of the central air-conditioning installation team, and have a strict and professional acceptance process to ensure that the installation of central air-conditioning meets the qualified standards, so that the use of central air-conditioning can play its due role, while reducing noise and prolonging the service life of equipment.
