The maintenance of central air conditioners is actually very troublesome. Due to the long-term operation of the central air conditioner, some problems such as dust, bacteria, scale, etc. will inevitably occur. These problems will directly lead to the weakening of the cooling and heating function of the central air conditioner. Life will be shortened, energy consumption will be relatively increased, and operation will increase costs. In order to save energy and reduce operating costs, please follow the decoration home Xiaobian to learn about the central air conditioning maintenance method.
First, the central air conditioning maintenance content
1, air conditioning host part:
Check whether the high pressure and low pressure of the refrigerant in the air conditioning main unit refrigeration system are normal; check whether the refrigerant in the air conditioning main unit refrigeration system leaks, whether it needs to be replenished with refrigerant; check whether the compressor running current is normal; check whether the compressor running sound is normal;
Check the compressor oil level, whether the color is normal; check whether the compressor oil pressure and oil temperature are normal; check whether the phase sequence protector of the air conditioner main unit is normal, whether there is any phase loss; check whether the terminals of the air conditioner main unit are loose; check the water flow protection Whether the switch works normally; check whether the resistance of the computer board and the temperature probe is normal;
2. Inspection of the wind system:
Check whether the air volume of the fan coil is normal. Check whether the return air filter of the fan coil return air collects dust; check whether the air temperature is normal.
3. Inspection of the water system:
Check the water quality of the chilled water, whether it needs to replace the water; check the impurities on the filter net in the chilled water system, and clean the filter; check whether there is air in the water system, whether it needs to be vented; check whether the return water and the effluent temperature are normal; Check whether the sound and current of the pump are running correctly; check whether the valve is flexible, rust-free, or leak-free; check whether the insulation system is cracked, damaged or leaking;
Second, the benefits of central air conditioning
1. Save space:
Whether the traditional air conditioner is a wall hanging machine or a cabinet machine, its indoor unit needs to be hung on the inner wall or placed on the ground. Not only this outstanding indoor unit is difficult to integrate with the overall home decoration, but also takes up such an important room space. And the area, the unit area of ​​20,000 or 30,000 yuan is not worth the loss.
The central air conditioner does not have this problem at all. It can be installed in a stealth by simply using a partial ceiling, and there is absolutely no exposed pipeline of the traditional air conditioner, leaving only a small air outlet. This "invisible invisible" installation effect not only frees up more home space, but also plays a finishing role in the decoration and accessories of fashion homes.
2, comfortable, precise temperature control:
The installation position of the ordinary wall-mounted machine or cabinet air conditioner is limited by the installation position of the outdoor unit. The indoor unit can only be installed on the wall near the outdoor unit. When cooling, the area where the air conditioner can blow directly is cold. The indoor temperature difference is obvious, and it is easy to get air-conditioning disease.
Compared with ordinary air conditioners, central air conditioners avoid air conditioners from blowing directly to the human body. Extra long piping allows air conditioners to be installed in the most comfortable position. The air outlets can be individually designed according to the owner's needs. The entire room can be air-conditioned. In the return air area, the indoor airflow distribution is more reasonable and uniform, the temperature can be maintained at a constant temperature of ±1 °C, and the dead angle of the indoor temperature is eliminated, which is naturally more comfortable.
According to the above content, you should also know how to maintain the central air conditioner. I hope that this content can help you. If you want to know more about the decoration information, please continue to pay attention to the decoration home network.
