Most air conditioning systems consist of 2 main parts:

1. The part inside the building is called a cooling unit or fan coil unit. It is responsible for delivering cold air into the building, consisting of an indoor coil, a fan coil blade, a fan motor. and air filter.
2. The part that is located outdoors is called a condensing unit. Also known as Comair. It helps to cool the heat from the air conditioner to the outside. Includes condenser, compressor, fan coil Motors & Electrical Panels

These two parts are connected by copper pipes and wires. The indoor unit absorbs heat in the room and discharges it through the indoor unit. Then the cold air generated by the air conditioner that has been lowered and pressured by the compressor becomes a cold air air blowing into the room.

Choosing the BTU size of the air conditioner to suit the space of the room. It will help the air conditioner to work at full efficiency. No energy consumption and cost savings

Do-it-yourself air conditioning care techniques

Every part of the air conditioner requires regular care. The following techniques are how to take care of and clean the air conditioner in the beginning that you can do yourself. To maintain good air in your home every day.

Warning:

For safety reasons, always turn off the switch or pull down the circuit breaker before disassembling, cleaning, or maintaining the air conditioner in any way. Water should not be sprayed into the electrical equipment area inside the unit, and any sturdy tray should be used to climb, remove or insert the device. Without expertise It is recommended to wash only the air filter and external surfaces. And call the air conditioner technician service for washing other parts every 6-12 days. months to prevent damage of internal electrical components.

1. Regularly remove and wash the air filter.

Air filter or air filter It is an important part that traps dust particles in the air from reaching the indoor coil. If not cleaned regularly, clogged accumulation of dust and various dirt will occur. As a result, the air conditioner works hard and does not cool as it should, or it may cause ice to settle on the indoor unit. And water drips from the machine. The filter is characterized by a grid that is usually made of synthetic fiber and has a plastic frame. When you lift the front cover of the machine, you will immediately encounter the filter. However, some air conditioners may have 2 types of filters: coarse filters for medium to large dust filtration. and fine filters for filtering fine particulate matter. The latter cannot be removed for washing and must be removed from the coarse filter before each wash. Removing the rough filter requires a simple process. Here's how:

Remove the filter with care to prevent dust from spreading.

Rinse with medium pressure water and use soapy water along with a soft brush to gently scrub to remove dust.

Dry and put it back on.

The frequency of filter depurification depends on many factors, such as the type of filter, the activation frequency, etc. Or the environment inside and outside the house, if it is a room next to the street or inside the house has a lot of dust. The filter should be removed and washed at least once a month, but if the dust is not large or not used frequently, it may be removed for 3-4 washes. once a year

2. Clean the indoor unit.

Indoor unit It is characterized by a pipe that curls back and forth along the length of the air conditioner. It is encapsulated in thin aluminum fins for frequent spokes. Acts as a cooling generator. Inside there is a refrigerant circulating. It works with a fan to receive and deliver cool air into the room. When the mask of the machine is removed, the indoor coil panel is immediately visible. Some models may be located under the filter. You will notice the small particles that can pass through the filter. Over time, it becomes so thick that air cannot pass through. As a result, the efficiency of the cooling system can be reduced as well as the problem of clogged filters.

The procedure for cleaning the indoor unit is as follows.

Use a toothbrush to drag along the line of the aluminum fin plate to remove any adhering dust.

Then spray or pour water gently to get the dust out of the water. Be careful not to splash the inside of the electrical equipment of the machine.

If the dust settles so sticky that it cannot be washed with water. Use an air conditioner cleaner spray for the indoor coil panel to help remove stains more easily. Spray evenly over the area and wait until it dries, then rinse with water. The water sprayed will flow into the drain tray of the air conditioner itself.

If the aluminum fin is bent or curved until it blocks until the air conditioner air is inconvenient, the coil comb may be used gradually. Brush the bending back to its original straightness. But it should be done carefully because this area is sharp, it can cause cuts on the hands. All in all. The spray foam used must be a cleaner that is specified for use on indoor coil panels. This ensures that there are no harmful residues and no damage to the components of the air conditioner.

3. Remove dust around the fan coil blades.

Fan coil blades or blowers are areas where cool air comes out. It is characterized by longitudinal slots. Serves to facilitate air circulation. This area is prone to dust. As a result, the air intake groove of the impeller is clogged. Sends out less cool air. As a result, it takes longer to cool. And it is one of the reasons why air conditioners consume more electricity. In addition, thick dust can cause the propellers to gain weight and lose balance, causing loud noises while the machine is running.

Some air conditioners may have an indoor coil blade shield, remove this part first.

Use water to spray dust around the fan coil blades.

This may be followed by an air conditioner cleaner spray for evaporator blades. Wait for the foam to dry, then spray water to rinse again.

Water that washes this area flows out of the air conditioner. In order not to mess up, an air wash bag should be used to cover the underside to accommodate the washed water.

4. Empty the drain tray and check the sewerage.

In addition to the indoor unit and fan coil blades. Water trays and sewer pipes are also parts that should be taken care of at the same time. Because it is the area where the water generated by condensation of steam flows together. It can become mucus and accumulate mold and bacteria that can affect the health of people in the house. To clean the water tray, you can scrub it with a hard bristle brush or remove it to wash and put it back in. Cleaning the sewer pipe may involve a blower or pressurized water sprayed inside the pipe. But it can only be done when ensuring that there are no leaks along the pipes. It is also worth checking whether the pipe has a bend, which may be a point of accumulation of water or dirt.

5. Regularly wipe down the chassis, air mask and supply mask.

The air conditioner in the structure or exterior surface should be cleaned or wiped with a damp cloth regularly. Or you can take it off and wash it.

6. Take care that the outdoor unit area is not obstructed.

It's not just the indoor unit that needs to be taken care of. Outdoor units are another part that should not be neglected as well. It may clog or obstruct the hot air vent and affect the performance of the air conditioner. This makes it less cool or consumes more power than usual. As for the care of the indoor unit, it is worth watching that the surrounding area is clean. No leaf litter. garbage or obstruction of the ventilation of the appliance. Dust accumulated in the indoor unit can be removed by preliminary manual by using water spray along the sides and back in an oblique direction towards the ground. without removing the lid. Do not spray directly to the inside of the machine as it may wet the electrical panel and cause damage.

7. Periodically activate the air conditioner.

Even during winters when the weather is not hot or unnecessary, it should be turned on periodically. To ensure that the unit is still working properly and to prevent insects or small animals from nesting. This may affect the operation of the appliance and bring musty or unpleasant odors.

8. Reduce the load on the air conditioner as much as possible.

During opening, make sure windows and doors are tightly closed. And it is not a good idea to use heat-powered appliances that will result in the air conditioner having to work harder to reduce the room temperature. Like Microw. Ovens, rice cookers, etc.

9. Check the setting mode of the remote.

Setting the operating mode to suit the air conditioner and its use contributes to the preservation of air conditioning usage and saves on electricity bills. You may set a power saving mode or set an automatic on-off timer every day to limit the time of use. In addition, the operation of the remote should be checked by observing it from the display screen. It should also be kept away from children and pets to prevent missetting. Or, if the remote is not used for a long time, the batteries should be removed. Regular maintenance of the air conditioner In addition to reducing electricity consumption. It also directly affects the good air quality in the house, allowing you to breathe fresh, odorless air, and sleep more comfortably. It also reduces allergy as well.
