How to clean the household central air conditioner?

First, turn off the power supply and remove the grille plate and filter screen of the air conditioner; Then put it into a vat filled with washing powder solution and wash it clean; Then wipe the surface of the air conditioner with a vacuum cleaner or rag; Finally, the grid plate and the filter are dried and put back in their original places as they are, so that they can be used normally.

The maintenance of central air conditioning system equipment mainly includes the following aspects:

Maintenance of chiller, air conditioning equipment, cooling water system, electrical control and other components.

Daily maintenance refers to the patrol inspection to find faults, deal with them in time and clean up the equipment during the operation on duty.

1. Maintenance of chiller.

2. Maintenance of fan coil unit and fresh air air conditioner.

3. Maintenance of cooling water and chilled water system.

4. Maintenance of electrical control part.

The central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. This system is different from the traditional refrigerant air conditioner, such as VRV, which centrally processes air to meet the comfort requirements. The principle of liquid gasification refrigeration is adopted to provide the required cooling capacity for the air conditioning system and offset the heat load of the indoor environment; The heating system provides the required heat for the air conditioning system to offset the cold and heat load of the indoor environment.

Maintenance and management of air-conditioning equipment mainly refers to regular and timely maintenance of central air-conditioning system and equipment and facilities to ensure that the performance of central air-conditioning equipment and facilities is in good condition, increase the service life of various equipment and facilities, and ensure the normal and safe operation of equipment.

The maintenance of air-conditioning equipment and facilities is highly technical, and the maintenance plan for the next year should be made at the end of each year. When making a plan, in order to make the plan accurate, reasonable, complete and clear, the national air conditioning system testing and technical service center and the maintenance team personnel should study and formulate the central air conditioning maintenance plan and communicate with users.

In the process of making central air-conditioning maintenance plan, the frequency of central air-conditioning, the operation status of central air-conditioning, whether there are hidden dangers and reasonable maintenance time (avoiding holidays and special events, etc.). ) should be taken into account. The contents of the maintenance plan mainly include: the content of the maintenance project, the specific implementation time of the maintenance, the estimated cost, the required spare parts and spare parts plan, etc.
