Preventive Service for your Air-conditioners

Preventive services for air-conditioning equipment primarily mean that you clean the coils of the air-conditioners . The clear benefit for the same is energy efficiency . The power consumption of your air-conditioner goes down when the coils are kept clean . Lets understand how this works. The preventive services are done in various ways based on the specific requirement of the machines .

Dry Service

This preventive service is done on a regular basis to remove the dust from the indoor and outdoor unit . The dry blower is used on the coils which blows the dust out of the coils . This improves the heat exchange and post service reduces the electricitry consumption . However this service does not remove the hard dirt that may continue to remain stuck in the fins of the coil .

Wet Service using a Jacket

The wet service is done when the machines are extremely dirty with hard solidifed dirt , the jacket around the unit ensures that the machines does not have to be removed and the servicing can be carried out without dirtying the space around the machine .This is an ideal way to clean the machines and ensure that the air conditioner remains clean and the energy consumption does not increase .

Brought Down Service

Often the machines are installed in a place where the coils are extremely dirty and cannot be serviced at site . This is when the machines has to be uninstalled transported to a service center and the the coils are seperated from the machine and jet spray is used to clean the coils. post the clean up the units are assembled back again and the machine is reinstalled .

Inefficiency in Preventive Service

There is no way to understand when a machine needs servicing and every company plans a preventive service based on a time duration like once in every quarter . This is inefficient as sometimes the machines needs preventive service more than once a quarter and some of them don’t need service even once in a quarter . This leads to unnecessary opening of machines that do not require servicing and waste of energy because machines that require frequent servicing cannot be done until the scheduled date .

Manufacturers Proposition to Solve this issue

Most manufacturers are building a self cleaning feature which is robotic device in front of the indoor coil , it takes the water from the drain and sprays it back on the indoor unit filter to remove the dirt . However this system fails to remove the hard dirt within the fins of the air-conditioning coils . In India the dusty and humid environment always creates hard dirt on the indoor and outdoor units of air-conditioners and that creates energy inefficiency in air-conditioners .

How to solve this issue in the future

In the future IoT devices in the air-conditioners could sense the rise in electricity consumption and the airflow at the coil . If the airflow is decreasing at the indoor unit and the the energy consumption is increasing rapidly from the manufacturers prescribed rating or the certified BEE energy label, then the device could send out a preventive service signal to a platform like Pureblu that self generates a trouble ticket and allocates a technician to have the preventive service done . This will ensure max energy efficiency and optimum utilisation of the technical manpower , Its not too long before this will become a reality .
