Why do central air conditioners need regular cleaning and maintenance
1、 If the central air conditioner is used for a long time, the bacteria will seriously exceed the standard
Central air conditioning has the title of "lung of modern architecture". Do you know why? As the central air conditioning controls the metabolism of air in modern buildings, more and more buildings adopt fully enclosed central air conditioning ventilation system. Due to the long-term operation of the central air-conditioning system, the ventilation system is easily polluted by fungi, bacteria, yeasts, molds, dust and other debris. If not cleaned and maintained, the pollution of central air conditioning will seriously threaten people's health and life safety. This is not alarmism, but seeking truth from facts.
2、 Dust accumulation in the central air conditioning pipe, easy to spread bacteria, bacteria
The humidity of the four walls of the pipe is very high, so the particles in the air are easy to adhere to it, and will form thick dust with the passage of time. The suitable temperature and humid environment here is a hotbed for bacterial reproduction. Central air conditioning through the pipeline to send such wind to the rooms of various areas, the consequences can be imagined.
3、 Regular cleaning of central air conditioning is conducive to energy saving
The investigation results show that different degrees of scale will be produced if the central air conditioner is not cleaned and maintained for a long time. If the scale thickness is 0.2-0.5mm, the heat exchange efficiency of central air conditioning will be reduced by about 33%, so the energy consumption of central air conditioning will be increased by about 20%. Therefore, to sum up, regular cleaning and maintenance of central air conditioning can save energy.
4、 Regular cleaning and maintenance is beneficial for central air conditioning to reduce failure rate and prolong service life
Before a netizen said: you said the service life of central air conditioning is 15-25 years? Why is the central air conditioner of our company not cold after seven or eight years of use? The refrigeration is very slow and sometimes stops? After investigation, it is found that the central air conditioner has never been cleaned after installation. Therefore, the reason for the failure of their company's central air conditioner is: if the central air conditioner is not cleaned for a long time, the accumulation of algae sludge and scale in cold water pipes will lead to poor heat transfer of equipment and pipes, and the heat transfer effect is not ideal. As a result, the main engine of the central air conditioner was running under high pressure, resulting in shutdown. If this situation continues, there may be a more serious situation, that is, the main engine corrosion and perforation, resulting in inevitable losses and unimaginable consequences. Therefore, regular maintenance and cleaning can not only extend its service life, but also reduce the failure rate.
