Air conditioners have long been an indispensable home appliance in home life. Whether it is used in winter or summer, air conditioners are used. When it comes to home air conditioners, you have to ask for air conditioners. How do you choose home air conditioners? How to choose the number of household air conditioners? The following decoration house decoration network Xiaobian will bring you the classification of household air conditioners and the purchase points, for the reference of everyone when purchasing air conditioners.
What types of household air conditioners are there?
Household air conditioners can be classified into single cold air conditioners and cold and warm air conditioners according to function classification. Single cold type: Suitable for areas where the summer is warmer and warmer in winter, or where there is sufficient heating in winter. Cold and warm type: It is suitable for hot and cold winter areas in summer, and should pay attention to selecting air conditioners with more heat than cooling capacity to ensure heating effect.
Household air conditioners can be classified into window air conditioners, wall-mounted air conditioners, cabinet air conditioners, ceiling air conditioners, embedded air conditioners, and central air conditioners according to their structural shape. Window air conditioner: indoor and outdoor unit is integrated, suitable for small-area rooms, easy to install and cheap, but noisy. Wall-mounted air conditioner: It is not limited by the installation position, it is easier to match with the interior decoration, the noise is small, and the installation quality is high. Cabinet air conditioner: high power, strong wind, suitable for large rooms, but noisy. Ceiling-type air conditioner: It occupies a very small ground, has a long air supply distance, and has good cooling effect, but it is not easy to clean due to the installation position. Embedded air conditioner: It occupies a very small ground, beautiful appearance, wide air supply area, good cooling effect, but high cost. Central air-conditioning: no indoor space, no exposed pipelines, high comfort, no dead ends, good decoration, but high price and complicated installation.
Household air conditioners can be classified into fixed frequency air conditioners and variable frequency air conditioners according to the working state of compressors. Fixed-frequency air conditioner: The compressor can only input the voltage of fixed frequency and size. The speed and output power of the compressor are unchangeable, and the power consumption is relatively large. Inverter type air conditioner: By changing the frequency and size of the input voltage to change the compressor speed and output power, the compressor speed is continuously changed, and automatic stepless speed change is realized. The temperature fluctuation is small, achieving fast, energy-saving and comfortable temperature control.

How to choose the number of household air conditioners?
The number of air conditioners refers to the cooling capacity and heating capacity of the air conditioner. Currently, the number of air conditioners on the market usually has 1P, 1P, 1.5P and 1.5P and 2P. These air conditioners mainly refer to the air conditioner in the bedroom. The number of horses in the living room is 2P, 3P and 5P.
In general, the cooling capacity of one horse is roughly 2,000 kcal, and the international unit should be multiplied by 1.162, so the cooling capacity of one car is 2000 kcal × 1.162 = 2324 (w), where w (瓦) means the cooling capacity, then 1.5 horses should be 2000 kcal × 1.5 × 1.162 = 3486 (w), and so on, according to this situation, it can roughly determine the number of air conditioning and cooling In general, 2200W to 2600W can be called 1 horse, 4500 (w)-5100 (w) can be called 2 horses, and 3200W-3600W can be called 1.5 horses. After the cooling capacity is determined, the cooling capacity can be estimated according to the actual situation of the household, and the appropriate air conditioner can be selected.
The "pile" of air conditioner is a power unit, which is the output power of the compressor motor, and the identification of the air conditioner model is marked with 100 times the nominal cooling capacity of the air conditioner. Usually, the nominal cooling capacity of one air conditioner is 2200W~ 2300W. The 2500W~2800W is a big one, and the 3200W-3300W is 1.5 horsepower. The nominal cooling capacity of a horse is 2200W~2300W. The 2500W~2800W is a big one, and the 3200W-3300W is 1.5 horsepower.
Generally, the household can calculate the cooling capacity of the air conditioner according to the size of the room, the quality of the sealing and insulation conditions, the floor, the orientation, the height, etc., according to the cooling capacity of 150-220W per square meter. Simple air conditioning in summer use air conditioning, the cooling capacity can be appropriately smaller, if the need for air conditioning heating and heating in winter, the cooling capacity should be appropriate. If the sealing and heat preservation conditions of the room are poor, the cooling capacity should be appropriately larger, the sealing and heat preservation conditions are good, and the cooling capacity can be smaller.
The cooling area of ​​1P heating and cooling machine is 10-16 square meters, and the heating area is 8-14 square meters; the cooling area of ​​1.3P cooling and cooling machine is 12-20 square meters, and the heating area is 9-16 square meters; 1.5P heating and cooling The on-hook refrigeration area is 14-22 square meters, and the heating area is 110-18 square meters; the 1.8P cooling and cooling on-hook refrigeration area is 18-29 square meters, and the heating area is 12-22 square meters.
