Sihaiwang: there are some details on the air conditioning of each of our houses that will be ignored. For example, the cooling capacity and power of the air conditioner are written on the nameplate of the air conditioner. What is the relationship between the cooling capacity and power of the air conditioner? Let's see the relationship between the two.
Relationship between cooling capacity and power of air conditioner
The cooling capacity and power of air conditioning are not directly related. In general, the higher the air conditioning power, the higher the refrigeration effect. But in this case, the air conditioning equipment should be the same. Generally speaking, there is no direct relationship between the two, if any, it can only be in the case of fixed energy efficiency ratio. In a certain energy efficiency ratio, the higher the power, the higher the cooling capacity.
Concept of refrigerating capacity and refrigerating power
Cooling capacity: the cooling capacity is the amount of heat that can be transferred from indoor to outdoor in unit time under the specified working condition of air conditioner, that is, the cooling mode. The more heat transferred per unit time, the higher the cooling capacity.
Cooling power: This is the power consumed by the air conditioner in unit time in the cooling mode. If one kilowatt hour is consumed, the cooling power is 1000W / h.
Air conditioning nameplate will write the cooling capacity and cooling power of the air conditioner. What's the relationship between the two? Let's see the relationship between the two.
What is the energy efficiency ratio of air conditioning
Air conditioning energy efficiency ratio is the ratio of air conditioning cooling capacity per unit time and the power consumed by air conditioning (that is, the cooling power).
If the cooling capacity of the air conditioner is 3500W, and the cooling power of the air conditioner is 1000W / h, the energy efficiency ratio is 3500 & pide; 1000 = 3.5. The energy efficiency ratio of the air conditioner is 3.5, so the air conditioner with higher energy efficiency ratio will consume less electricity when meeting certain indoor cooling demand. Whether the air conditioner saves electricity only depends on the energy efficiency ratio. The higher the energy efficiency ratio, the less power.
