6 things to note when installing air conditioners to avoid "wasting electricity"
(Baonghean.vn) - In the summer, the demand for air conditioner installation always increases; but don't think that only technicians need to know how to install air conditioners, and buyers don't. Users also need to know how to install them properly - to be able to check whether their home machine is up to standard or not.
The following notes will help install the machine properly, increase cooling efficiency and save energy.
1. Choose the right capacity
 |
To have a suitable location for installing the air conditioner, you must first know the exact area or more specifically the volume of the family room. For a normal bedroom, the area is less than 20m2.2, an air conditioner with a capacity of 9,000 BTU is enough; 12,000 BTU will be suitable for a room area of 20 - 30m2;Higher is 18,000 BTU, but usually the bedroom only needs 2 air conditioner lines 9,000 and 12,000 BTU is enough.
Being careful in choosing an air conditioner will help save a lot of money on your family's monthly electricity bill.
2. Determine the location of the indoor unit

The principle of installing the condenser is to avoid direct sunlight and places with high temperature differences such as doors and windows. Because the cold air directly meets the hot air, it will condense, causing the machine to "sweat" and drip.
If the condenser is installed in a location where the hot air is blocked and has no way to escape, it will affect the operating capacity and consume more electricity.
It is best to install the machine so that the air flow runs along the length of the room; it should not be directed horizontally or at an angle because this will cause uneven cooling in the room.
The location also needs to be calculated to suit the people who often live in the room; for example, for the elderly and children, the machine should be placed far from the bed; the common room needs to blow air directly to the central area...
3. Location of condenser installation

This is an issue related to exterior design. If not calculated when building a house, you will be passive in installation and will not have many suitable alternatives.
Outdoor condenser should be placed in a shady location, away from wind and without obstacles in front;However, do not cover it too tightly because it will affect the heat dissipation process and easily damage the machine.
According to the experience of experts, you should use heat-resistant silver sheet to cover or frame the hot block with insulating material. This measure can help save electricity from 5% to 10%. Another thing to note is to avoid the position where the wind blows directly into the air conditioner fan, causing resistance and energy consumption.
4. Copper pipe size
 |
Copper pipes for air conditioners must correspond to the capacity to achieve high efficiency. As vHey1 HP machine (9000 BTU)Use copper pipe with outer diameter of 10 mm;1.5 HP machine (12000 BTU)use 10mm or 12mm tube;2 HP machine (18000 BTU)use 12mm tube;2.5 HP machine (24000 BTU)use 16mm tube...
Similar to the size section, the length of copper pipe connecting the condenser and evaporator must also comply with the installation requirements specified by the manufacturer.
If the copper pipe is installed too short, the solvent/gas will not return to the compressor in time and will be blocked, causing serious damage. If the copper pipe is installed too long, the machine will cool slowly.
5. Drainage location
 |
So when installing drainage pipes, pay attention to the following factors:The pipe should not be too long or bent; it must have a slope to ensure water can drain from the evaporator quickly and effectively.
For pipes placed underground in the wall, it is necessary to cover them with an insulating layer because cold water can affect the wall structure, easily causing mold or cracking.
Do not plug the waste pipe into the drain because the bad smell will follow the pipe into the room.
6. Reasonable interior layout
 |
To increase the cooling efficiency, pay attention to the arrangement of furniture in the air-conditioned room; avoid placing large objects such as cabinets, shelves, etc. to cover the machine, obstructing the cold air flow, making the room take a long time to cool.
In addition, you can choose to buy air conditioners with a triangular design; this design helps cool quickly thanks to the wide air intake, taking in more air. The width, angles of the air outlet and the number of air blades are also improved; the large fan pushes the cold air further and evenly to many corners of the room.
