1. The choice of the number of air conditioners The 'horse' in the number of air conditioners is a unit of power. One horse is equal to 735W. According to our country's custom, it is generally expressed in terms of output power, indicating the cooling capacity of the air conditioner, that is, the size of the cooling capacity. The cooling capacity of an air conditioner is about 2500W, which is suitable for use in a room of about 12 square meters, and the cooling capacity of an air conditioner of two horses is about 5000W, which is suitable for use in a room of about 25 square meters. In general households, the cooling capacity of the air conditioner can be calculated according to the size of the room, the quality of the sealing and heat preservation conditions, the floor, the orientation, and the height, and the cooling capacity per square meter is 150~220W. Simply use refrigeration and air-conditioning in summer, the cooling capacity can be appropriately small, if the air conditioning is needed for heating in winter, the cooling capacity should be appropriately larger. If the room's airtight and heat preservation conditions are poor, the cooling capacity should be appropriately larger, and if the airtight and heat preservation conditions are good, the cooling capacity can be lower. Therefore, according to the relationship between the number of horses and the cooling capacity, you can refer to the parameters to select the size of the air conditioner. Suitable air conditioner for a room of 10 square meters: 1 air conditioner; Suitable air conditioner for a room of 15 square meters: 1-1.5 HP; Suitable air conditioner for a room of 20 square meters: 1.5 HP; Suitable air conditioner for a room of 30 square meters: 2 Horses-2.5 horses; suitable air conditioners for a 40 square meter room: 2.5 horses to 3 horses; suitable air conditioners for a 50 square meter room: 3.5 horses to 4 horses; suitable air conditioners for a 70 square meter room: 5 horses to 6 horses. 2. What is the difference between fixed speed and variable frequency? When we buy air conditioners, there are generally two types of fixed speed and variable frequency in the market. So, should we buy fixed speed or variable frequency? What is the difference between the two? Woolen cloth? In fact, the difference between inverter air conditioner and fixed speed air conditioner is mainly in the following aspects: 1. Structure Inverter air conditioner adopts frequency converter in structure, and the frequency of the power supply is changed by the frequency converter to make the compressor speed (power) continuous from minimum to maximum. variable. The fixed-speed air conditioner cannot change the speed of the compressor. 2. Refrigerant model Inverter air conditioners generally use R410A refrigerant, while fixed-speed air conditioners use R22 refrigerant. 3. Installation method Since the inverter air conditioner uses a mixed refrigerant, the difference between the installation and the fixed speed air conditioner is that the inverter air conditioner must be installed after being evacuated, while the fixed frequency air conditioner does not need to be evacuated. 4. Control accuracy The inverter air conditioner uses a frequency converter, which can make the compressor power continuously variable. Therefore, when the temperature reaches the set temperature, the air conditioner will continue to work at the lowest power to maintain this temperature, so the control accuracy is high. The fixed-speed air conditioner controls the temperature to change within a certain range by starting and stopping, and the accuracy is low. 5. Energy-saving Inverter air conditioners using frequency converters have better energy-saving effects in principle, and their energy-saving effects are better than fixed-speed air conditioners, but due to the influence of many factors, such as the heat insulation effect of the room, the outdoor temperature, etc., Its energy-saving effect did not reach the effect stated in the propaganda. 6. Price Since the inverter air conditioner uses a frequency converter, it is a new type of air conditioner, so its price is higher than that of a fixed speed air conditioner.
