How to buy a home air conditioner? How to choose the number of home air conditioning?

Air conditioning has long been one of the indispensable appliances in home life, whether it is winter or summer will be used to get the air conditioning, and when it comes to home air conditioning will have to mention the issue of air conditioning purchase, then how to buy home air conditioning? How to choose the number of household air conditioning? Below we will bring you the classification of home air conditioning and purchase points, in order to buy air conditioning for reference.

What are the types of home air conditioners?

Household air conditioners can be categorized into single-cooling air conditioners and heating and cooling air conditioners according to their functions. Single-cooling type: suitable for areas with hotter summers and warmer winters, or areas with adequate winter heating. Heating and cooling: for hot summers and cold winters, and attention should be paid to the choice of heating capacity is greater than the cooling capacity of the air conditioner to ensure that the heating effect.

Household air conditioners can be divided into window air conditioners, wall-mounted air conditioners, cabinet air conditioners, ceiling air conditioners, built-in air conditioners and central air conditioners according to the structure of the shape classification. Window air conditioner: indoor and outdoor units into one, suitable for small rooms, easy to install and cheap, but noisy. Wall-mounted air conditioner: not subject to installation location restrictions, easier to match with the interior decoration, low noise, the need for installation of high quality. Cabinet air conditioner: large power, strong wind, suitable for large rooms, but noisy. Ceiling air conditioner: occupies a very small floor, air distance, cooling effect, but by the installation location restrictions, not easy to clean. Embedded air conditioner: occupies a very small floor, beautiful and generous, wide air supply area, good cooling effect, but the cost is high. Central air conditioning: does not take up indoor space, no exposed pipelines, high comfort, no dead ends of the wind, good decorative, but the price is higher, the installation is complicated.

Home air conditioning can be divided into fixed-frequency air conditioning and inverter air conditioning according to the compressor working state classification. Fixed-frequency air conditioning: the compressor can only input a fixed frequency and size of the voltage, the compressor speed and output power is not changeable, power consumption is relatively large. Inverter air conditioner: by changing the frequency and size of the input voltage to change the compressor speed and output power, so that the compressor speed continuous change, realizing the automatic stepless speed change. The temperature difference fluctuation is small, realizing fast, energy-saving and comfortable temperature control effect.

How to buy a home air conditioner?

Therefore, try to choose a reliable installation, after-sales team of dealers and manufacturers.

How to choose the horsepower of home air conditioning?

Air conditioner horsepower is to indicate the size of the air conditioner's cooling capacity and heating capacity, the current market air conditioner horsepower usually 1P, big 1P, 1.5P and big 1.5P and 2P, etc., these kinds of air conditioner horsepower mainly refers to the bedroom inside the air conditioner horsepower, and living room air conditioner horsepower has big 2P, big 3P and big 5P and so on.

Generally speaking, the cooling capacity of 1 horsepower is committed to 2,000 calories, converted to international units should be multiplied by 1.162, so the cooling capacity of 1 horsepower should be 2,000 calories × 1.162 = 2,324 (w), here w (w) that is, that is to say the cooling capacity of 1.5 horsepower should be 2,000 calories × 1.5 × 1.162 = 3,486 (w), and so on, according to the situation. According to this situation, the number of air conditioning and cooling capacity can be roughly determined, in general, 2200W 2600W can be referred to as 1 horsepower, 4500 (w) -5100 (w) can be referred to as 2 horsepower, 3200W 3600W can be referred to as 1.5 horsepower. After determining the cooling capacity, you can estimate the cooling capacity according to the actual situation of their families, choose the right air conditioner.

The air conditioner "pi", is a power unit, is expressed in the output power of the compressor motor, and air conditioning model identification is the air conditioner's nominal refrigeration capacity of 100 times to indicate that the nominal refrigeration capacity of the usual pi of 2200W ~ 2300W. 2500W ~ 2800W for the big one, 3200W - 3300W for the large one. 3200W-3300W is 1.5 horsepower. The nominal cooling capacity of a one-horsepower is 2200W~2300W. while 2500W~2800W is the larger one, and 3200W-3300W is 1.5 horsepower.

General household can be based on the size of the room area and sealing and insulation conditions, floor, orientation, height and other factors, according to the cooling capacity per square meter with 150-220W to calculate the size of the air conditioning cooling capacity. Simply summer cooling using air conditioning, cooling capacity can be appropriately small, if the winter needs air conditioning heating heating, cooling capacity should be appropriately larger appropriate. Room sealing and insulation conditions are poor, the cooling capacity should be appropriately larger, sealing and insulation conditions are good, the cooling capacity can be smaller.

1P heating and cooling hanging machine cooling area of 10-16 square meters, heating area of 8-14 square meters; 1.3P heating and cooling hanging machine cooling area of 12-20 square meters, heating area of 9-16 square meters; 1.5P Heating and cooling hangers have a cooling area of 14-22 square meters and a heating area of 110-18 square meters; 1.8P heating and cooling hangers have a cooling area of 18-29 square meters and a heating area of 12-22 square meters.
