The power consumption of the air conditioner is determined by the cooling power of the air conditioner, that is, the energy consumption ratio of the air conditioner. For the same number of air conditioners, the higher the energy efficiency ratio, the lower the power consumption. Whether the household central air conditioner saves energy mainly depends on the energy efficiency ratio. Next, I will introduce to you in detail:

The high electricity cost of domestic central air-conditioning is actually a misunderstanding. The indoor unit in each room can be adjusted and operated independently. It can be turned on separately according to the user demand. The outdoor unit can adjust the power consumption according to the number of indoor units turned on.

In terms of the initial investment cost, the domestic central air conditioner is higher than the ordinary wall mounted and cabinet type air conditioner. However, for the multi room and large family type residence, when all indoor units are fully opened, the multi online air conditioner saves more power than the traditional air conditioner, and the long-term use cost is less than the ordinary split air conditioner.

The central air conditioning system is divided into the fluorine system and the water system. The frequency conversion technology of the fluorine system is mature and energy-saving and efficient. However, the home central air conditioner is a rare water system central air conditioner that uses frequency conversion technology. Its cooling air is soft and comfortable and energy-saving.

When the temperature difference between inside and outside the room is large, when the variable frequency air conditioner is just started, it will operate with high power and frequency to quickly adjust and cool. The power consumption is large in a short time, but after the continuous operation for a long time, the room will enter the constant temperature state, and the variable frequency air conditioner will save more power than the constant frequency air conditioner of the same number.

Whether the household central air conditioner saves electricity or not depends on the energy efficiency ratio of the product. The higher the energy efficiency ratio, the more energy saving; Whether it consumes electricity depends on the compressor technology. The higher the IPLV, the more power it saves. in

The power consumption of the air conditioner is directly related to the cooling capacity, but the output power representing the cooling capacity is not a direct comparison parameter of the power consumption. For example, it is not that an ordinary 1-piece air conditioner with a cooling capacity of 2500 w needs to consume 2.5 degrees of power for one hour of continuous operation. The calculation formula of power consumption can be used to multiply the actual cooling power by the use time. However, the power consumption of the air conditioner is not only related to the cooling power of the air conditioner but also related to the ambient temperature, the indoor temperature setting, the room size and the sealing and insulation conditions.

The power consumption of variable-frequency central air conditioning is different between full load operation and low-speed operation, and only the approximate power consumption range can be calculated.

Does the central air conditioner cost electricity? That's all I've introduced to you today. It should be noted that the energy consumption of the central air conditioner will change with the rise and fall of the temperature. Blindly setting the temperature too low or too high will often increase the energy consumption of the central air conditioner. When cooling, the temperature is set to 26 degrees, and when heating, the temperature is set to about 20 degrees. The power consumption is related to many factors such as the number of people in the room and the tightness of the room. The tightness of the air-conditioned room is better. The windows should be closed tightly during use to keep the cold air from losing; Do not open and close doors frequently for indoor personnel; The light in the room is too strong. The curtains can be drawn during the day to block some of the heat.
