Use of
- Enter the area of the space to be refrigerated as a flat or m2. If the living room and kitchen are fitted, add it together.
- Choose the highest floor, large window (south, south) with strong sunlight, insulation level, resident staff.
- Press to calculate to display the required cooling capacity (kW) and the recommended balance, product range (wallband/stand) that meets this.
Refrigeration – Refrigeration is a measurement.
The starting point for the selection of air conditioning capacity is the heat the space accepts in summer, i.e. the cooling load. This calculator is used in domestic residential space under the standard cooling load. Approximately 130W/m2Use the default value, and use a method to add weight to the conditions where the heat flow is increased.

Example: 18 square (59.5m2) living room + kitchen, no upper floor, with large windows to the back, insulation usually, if you are a 3-person family — basic load 59.5m2 × 130W = 7,735W window repair +10% attached to approximately 8,509W, that is approximately 8.5 kWThere is a need for cooling capacity. There is a near 23 flat (8.3kW) stand air conditioning standard, but it is slightly insufficient, so 25 flat (9.0kW) is recommended. If the same 18 flat is the standard condition, 7.7kW is the appropriate range of 20 flat (7.2kW) to 23 flat. This makes it normal for the house flat and the climate balance to differ.
The recommended balance is based on the product cooling capacity table below, choosing the smallest model that meets the required cooling capacity.
| Balanced indicator | The cooling ability. | The ordinary product. |
|---|---|---|
| Sixth level | 2.3kW | The walls |
| Seven levels | 2.5kW | The walls |
| 9th level | 3.5kW | The walls |
| 11 is equal | 4.0kW | The same wall. |
| Thirteen levels | 5.0kW | Standed |
| 15 to 16 | 5.8~6.0kW | Standed |
| 17 to 18 | 6.3~6.5kW | Standed |
| 20 is equal | 7.2kW | Standed |
| 23nd level | 8.3kW | Standed |
| 25th level | 9.0kW | Standed |
The above compensation is a reference near value that simplifies the general conditions of the residential space. The space with a heat source such as a high floor, commercial space (restaurant, office), server, cooking machine, etc. requires a professional cooling load calculation. The manufacturer/model cooling capacity may vary from the indicative balance, so check the kW value of the spectrum before purchase.
Knowing good information.
Air conditioning is more damaged when the capacity is lacking. Lacked capacity returns to maximum output throughout the summer, while electricity charges are higher and outdoor life is shorter, inverter products are more efficient to switch to low output driving after the capacity has reached a one-step high-set temperature. When the budget is low, choosing the big side is the peak, not the small side.
The same balance, depending on energy-efficiency and cooling efficiency (SEER), varies by tens of thousands for a summer iron electricity fee. The price difference between 1st to 2nd class products is usually recovered within two to three years, as long as you use a household appliance. Installation environment is also important. If the outdoor air is stuck in an outdoor room with direct sunlight or not ventilated, the performance of the cooling room can drop by more than 10 percent, and the performance of the outdoor air is also improved by ensuring ventilation and ventilation.
If you are concerned about summer electricity charges, check the empty range as well. If you multiply the daily operating time by air conditioning power consumption (not by cooling capacity, but by power consumption, usually 1/3 to 1/4 of cooling capacity), you can estimate the additional monthly usage, Electricity calculation.If you do, the estimated price will come right away.
Frequently asked questions.
Is the “air conditioning” the same as the real home?
Different. Air conditioning balance is the usual expression of the refrigerable area indicated by the manufacturer, an assumption of the standard conditions (middle-layer/normal insulation). Even if the same 18-floor living room is the top floor or has a large window to the west, it actually requires a larger refrigeration capacity. So it is correct to choose the refrigeration capacity (kW) rather than the flat house, and this calculator recommends the appropriate balance for the refrigeration capacity that needs the condition correction.
If there is a living room + kitchen, how should I put the space?
If the living room and the kitchen are open, enter the area of the two spaces together. To cool the room connected to the hallway, add the area, in which case the actual cooling room depends on whether the door is opened.
Do you pay more electricity if you buy more electricity?
In these days, inverter air conditioning drives the output lower when it reaches the set temperature, so a one-step-larger product than a reasonable capacity often uses less electricity. Lack of capacity air conditioning continues to consume more electricity back to the maximum output and also shorter life. On the contrary, excessive capacity is a waste of purchase cost, so it is reasonable to choose from the range of 100 to 120% of the required cooling capacity.
What to choose between walls and stands?
Required cooling power is the standard. Generally, the walls are 5 to 9 flat (2.0 to 3.5kW), the stands are 13 flat (5,0kW) or higher. Independent rooms such as bedrooms are walled, living room + kitchen, large spaces are standard stands, and the two-person (stand + wall set) can cover two spaces with one outdoor device to save installation costs.
I’m already using a smaller balance than the calculation result and I’m cool.
This calculator is based on the capacity that can beined within 26 degrees in mid-summer precipitation (33-35 degrees) and beyond. Usually, it can be cool enough with a small capacity, but on a day of precipitation it may be inadequate in the form of cooling or not humidifying. Also, northward, low and isolated houses can be low in compensation and the actual capacity needs may be small.
