Question about the meaning of cooling capacity on the refrigerator’s nameplate?

The conversion factors between various cooling capacity units are as follows: 1. 1 kcal/h (kilocalories per hour) = 1.163 W, and 1 W = 0.8598 kcal/h； 2. 1 Btu/h (British thermal unit per hour = 0.2931 W, 1 W = 3.412 Btu/h) ； 3. 1 USRT (U.S. refrigeration ton = 3.517 kW; 1 kW = 0.28434 USRT) ； 4. 1kcal/h = 3.968 Btu/h, 1 Btu/h = 0.252 kcal/h ； 5. 1 USRT = 3024 kcal/h; 10,000 kcal/h = 3.3069 USRT ； 6. 1 horsepower = 2.5 kW (for air-cooled units), 1 horsepower = 3 kW (for water-cooled units). Note: 1. When used as a unit of power, \"horsepower\" is expressed as Hp (imperial horsepower) or Ps (metric horsepower); 1 Hp (imperial horsepower) = 0.7457 kW, 1 Ps (metric horsepower) = 0.735 kW ； 2. The cooling capacity of small and medium-sized air conditioning refrigeration units is commonly expressed in “horsepower,” while that of large air conditioning refrigeration units is usually expressed in “tons of cooling (U.S. tons).” A tonnage is commonly used to denote central air conditioning systems with high power; 1 tonne equals 3024 kilocalories, or 3516 watts. The calculation is done in terms of kilocalories per hour (KCAL/H) or watts (W). Generally, a household air conditioner with a capacity of 1 horsepower corresponds to a cooling capacity of around 2000 kilocalories, or 2324 watts (1 kilocalorie = 1 Kcal/hour = 1.161 watts). The coefficient of performance for central air conditioning is between 4 and 5. The cooling capacity of air conditioners can be expressed in terms of horsepower (PH) or tons of refrigeration (RT). Horsepower is a unit of power, with 1 PH equal to 745 W; to convert this value into cooling capacity, it is necessary to multiply by the coefficient of performance ε, which ranges from 2.8 to 5. Tons of refrigeration are another unit used to express cooling capacity, and they are typically used to describe central air conditioners with high power output. One ton of refrigeration equals 3024 kcal, or 3516 W. The calculation is done in units of kcal/h or watts. Generally speaking, a household air conditioner with 1 horsepower has a cooling capacity of around 2000 kcal, or 2324 W (1 kcal = 1 Kcal/h = 1.161 W). The coefficient of performance for central air conditioning is between 4 and 5

Cooling capacity/actual motor power = COP. The cooling capacity represents the heat transfer amount of the evaporator
