Why does refrigeration equipment particularly emphasize installation?
Hidden danger 1: The refrigerant pipe enters dust and impurities
Dust and impurities in the refrigerant pipeline will cause the effect of the central air conditioner to decrease, increase the wear of the central air conditioner compressor, and cause the central air conditioner to block and affect the cooling effect.
Hidden danger 2: Leakage of refrigerant pipeline
Leakage of the refrigerant pipeline will reduce the overall cooling effect of the central air conditioner. During this period, the long-term overheating operation of the compressor is extremely easy to reduce the service life of the central air conditioner. In the later maintenance, it will affect the completed ceiling and shape.
Hidden danger 3: insufficient space for unit installation
Insufficient installation space of the unit is one of the reasons for the reduction of the central air conditioning effect. Because the installation space of the unit is insufficient and the circulation distance between the air outlet and the return air outlet is too close, the air circulation of the central air conditioner is short-circuited, causing the heat exchange effect to decrease, leading to the central The air conditioning effect becomes worse. Secondly, the installation space of the unit is too small, and there is not enough space for maintenance personnel during maintenance and overhaul, and the interior decoration needs to be damaged to perform repairs.
Hidden danger four: wrong power supply and control wiring
Miswiring of the central air-conditioning unit will accelerate the damage of electrical components, and may even cause the unit to run chaotically, so that independent control or centralized control cannot be achieved, and the central air-conditioning system cannot operate.
Hidden danger five: insufficient discharge of condensate pipeline
Central air-conditioning will produce condensate during the cooling process, and whether the condensed water can be discharged smoothly is the key to the installation of central air-conditioning. After connecting the condensate pipe from the internal machine to the outdoor or floor drain, maintain a slope of at least >1%. When the condensate pipeline discharge is insufficient, the indoor unit will leak water, destroy the interior decoration, and cause a short circuit of the power supply.
Hidden danger six: improper installation of external machines
When installing the outdoor unit, it is necessary to ensure that there is no obstruction within 1 meter of the air outlet of the outdoor unit's fan, and no obstruction within 15 cm of the rear of the outdoor unit. All floor feet must be installed with shock absorbers to ensure the normal operation of the outdoor unit. Improper installation of the external unit will often short-circuit the airflow, and the protection switch action caused by the short-circuit of the airflow will cause the hot and cold air discharged from the central air conditioner and the noise of the unit to affect the surrounding environment.
Hidden danger 7: The setting of the indoor unit's return air outlet is unreasonable
The unreasonable setting of the air outlet of the indoor unit will lead to improper airflow organization and dead angle of the air conditioner. It even produces large operating noise, insufficient maintenance space, insufficient installation strength, and abnormal vibration.
Therefore, the position of the air outlet of the central air-conditioning indoor unit usually needs to consider two aspects. One is to meet the normal air supply organization of the air conditioner to ensure that there is no dead angle in the air supply, and the other is to meet the overall interior decoration style design as much as possible.
