The following notes from Nashville Contractors will help to properly installing an air conditioner, increase cooling efficiency quickly and save energy.
1. Choose the right capacity
To have a suitable place to install the air conditioner, you must first know the exact area or more specifically the volume of the family room. For a normal bedroom with an area of less than 20m2, an air conditioner with a capacity of 9,000BTU is enough; 12,000 BTU will be suitable for room area from 20 – 30m2; higher than 18,000BTU, but usually bedroom only need 2 lines of 9,000 and 12,000 BTU air conditioners are enough.
Being careful in the selection of air conditioners will help save a lot of monthly electricity bills for your family.
2. Determine the installation location of the indoor unit
Principle of indoor unit installation must avoid places where direct sunlight shines on, where there is a high temperature difference such as doors and windows. Because the cold air directly meets the hot air, it will condense, causing the machine to “sweat” and drip water.
If the indoor unit is installed in a location where the hot wind is obscured, it will be difficult to escape, which will affect the operating capacity and consume more power.
It is best to install the machine so that the airflow flows along the room; Do not let the wind direction blow horizontally or at an angle because that way the cold air in the room will be uneven.
The placement also needs to be calculated to suit people who often live in the room; As with the elderly, children should keep the device away from the bed; The common room needs to blow direct wind to the central area…
3. Location of outdoor unit installation
This is a problem related to exterior design, if you do not calculate when building a house, you will be passive in installation, there are not many suitable alternatives.
Outdoor outdoor unit should choose a shady location, avoid a place where there is no wind, no obstacles in front of you; 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, it is recommended to use heat-resistant silver sheet to shield or frame the hot block with insulation. This measure can help save electricity bills from 5% to 10%. Another thing to pay attention to is to avoid the position where the wind blows directly into the air conditioner fan, causing resistance and energy consumption.
4. Copper tube size
Copper pipes for air conditioners must correspond to the capacity to achieve high efficiency. As with the 1 HP (9000 BTU) machine, copper pipes with an outer diameter of 10 mm are used; 1.5 HP (12000 BTU) machines using 10 mm or 12 mm tubes; 2 HP (18000 BTU) machine using 12 mm tube; 2.5 HP (24000 BTU) machine using 16mm tube…
Similar to the size section, the length of copper pipes connecting the outdoor and indoor units must also comply with the installation requirements specified by the manufacturer.
If the copper pipe is too short, the solvent/gas will not return to the compressor in time and become blocked, causing serious damage. If the copper tube is installed too long, it will slow down the chiller.
5. Location of drainage line
Draining the air conditioner will affect the performance and life of the air conditioner. Because in the process of operation, the average amount of wastewater is from 6 -12 liters/day and night, depending on each line and machine capacity.
Therefore, when installing the drainage pipe, it is necessary to pay attention to the following factors: The pipe should not be too long or bent; must have a slope to ensure that water can escape from the indoor unit quickly and efficiently.
With pipes placed underground in the wall, it is necessary to cover with an insulation layer because cold water can affect the wall structure, easily causing mold or cracking.
Do not plug the sewage line down the drain because the smell will follow the pipe into the room.
6. Reasonable interior layout
To increase the efficiency of fast cooling, it is necessary to pay attention to the arrangement of furniture in the air-conditioned room; Avoid placing large objects such as cabinets, shelves, etc. to obscure the machine, obstructing the flow of cold air, making the room cool for a long time.
In addition, you can choose to buy air conditioners with three-sided design; This design helps to cool quickly thanks to the wide air intake, taking in more air. The width, angles of the air intake and the number of air flaps have also been improved; Large fans push cold air farther and spread evenly to many corners of the room.
