There is a refrigerator, its main technical parameters table has a column called power consumption (kW. H / 24h), the data is 0.66, you know

The daily power consumption is 0.66 degree, but this is the data of the manufacturer in the laboratory. In actual use, it is about 1 degree tomorrow

The rated voltage of the refrigerator is 220 V, the total input power is 120 W, and the power consumption is 1.1 (KWH) / 24 h. connect it to the 220 V circuit separately for one minute, and the circuit is marked with "3000" in it
How many turns does the turntable of the electric energy meter with the word "R / (KWH)" turn? (calculated according to 30 days) how much electricity consumption per month?

The total rated power of the refrigerator is 120W (0.12kw), which is connected to the 220 V circuit separately and runs for one minute
3000 / 60 × 1 × 0.12 = 6 (revolutions)
When the refrigerator is set according to the operating instructions, the average daily (24 hours) power consumption is about 1.1 degrees (the power consumption will increase when the setting temperature is too low)
1 × 30 = 33 (degrees)

Xiaodong's refrigerator's name plate is shown in the following table. When Xiaodong's household appliances only have refrigerator working, it takes 6min to observe the refrigerator from start to stop working, and the turntable of the electric energy meter turns 18 times. Then the refrigerator actually works in one day when it works with rated power consumption______ h. Start up______ Each time, every 1 kilowatt hour consumed, the meter turns______ Power consumption 0.72kw · H / 24h rated voltage 220V refrigerating capacity 4kg input power 120W refrigerant R600a climate type n · st

(1) According to the data in the table, the electric energy consumed by the refrigerator in a day is 0.72kw · h, the input power of the refrigerator is 120W = 0.12kw, ∵ P = WT, ∵ the actual working time of the refrigerator every day t = WP = 0.72kw · h0.12kw = 6h; (2) the starting time of the refrigerator is 6min = 110h, and the starting times of the refrigerator every day is 6h110h = 60; (3) ∵ P = WT, ∵ the electric energy consumed by the refrigerator every starting time W1 = Pt 1 = 120W × 60s × 6 = 43200j, suppose that the power consumption is 1 kwh, and the number of turns of the meter is n, then w1n1 = wn, that is: 43200j18 turns = 3.6 × 106jn, then n = 1500 turns; so the answer is: 6; 60; 1500
