How Do You Calculate KW Per Tr?

1. kW/ton = 12 / EER.
2. kW/ton = 12 / (COP x 3.412)
3. COP = EER / 3.412.
4. COP = 12 / (kW/ton) / 3.412.
5. EER = 12 / (kW/ton)
6. EER = COP x 3.412.

What is COP formula?

_{COP =}

|Q| W

. COP is defined as the relationship between the power (kW) that is drawn out of the heat pump as cooling or heat, and the power (kW) that is supplied to the compressor.

How do you calculate kW tonnage?

The theory is below. Therefore, 1 Ton of cooling = (12,000 BTU/h)*(1 kWh)/(3412.142 BTU) = 3.5168 kW. So if you want to figure out how many Tons of cooling is required for x number of kW of power consumed [or heat generated],

simply divide the total kW by 3.5168

.

How do you calculate kW for refrigeration?

Using the energy equation of

Q = ṁ x Cp x ΔT

we can calculate the cooling capacity. We add 273.15K to the celcius to convert it to units of Kelvin. The Specific heat capacity (Cp) is measured in units of kJ per kg per Kelvin. This gives us a final answer of Q = 2,500kW of cooling.

How many kW is in a ton?

The theory is below. Therefore, 1 Ton of cooling = (12,000 BTU/h)*(1 kWh)/(3412.142 BTU) =

3.5168 kW

. So if you want to figure out how many Tons of cooling is required for x number of kW of power consumed [or heat generated], simply divide the total kW by 3.5168.

How many kW is a kWh?

1 kWh equals one hour of electricity usage at a rate of 1 kW

, and thus the 2 kW appliance would consume 2 kWh in one hour, or 1 kWh in half an hour. The equation is simply kW x time = kWh.

How many kW is a 4 ton AC?

The exact amount of Watts needed for a 4 ton air conditioner depends on the make and model of the AC unit, as well as how often it's running. A safe estimation is that it takes 14,000 Watts, or

4 Kilowatts

.

Can COPs be less than1?

Can cops be less than1? The coefficient of performance (COP) of

refrigeration is always more than 1

. … COP is the ratio of heat extracted from the refrigerator to the work done on the refrigerant. Thus it is but obvious that the value of COP is bound to be greater than unity since efficiency is always less than 1.

Is a higher COP better?

The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required.

Higher COPs equate to higher efficiency

, lower energy (power) consumption and thus lower operating costs.

What is SI unit of refrigeration?

Explanation:

KJ/s or KW

is the S.I. unit of refrigeration, which is converted to Tonnes as commercial unit.

How many kW is a BTU?

What is cooling capacity in kW?

The cooling capacity of

1 ton is equal to 3.517 kilowatts of power

. For 1.5 ton AC, the power consumption is the same as the cooling capacity. There was a value of 1.5* 3.517/2.954 kilowatts.

How do you calculate TR?

Total revenue is the price of an item multiplied by the number of units sold:

TR = P x Qd.

Is kW and kWh the same?

A kilowatt-hour measures the energy an appliance uses in kilowatts per hour. … The difference between kWh and kW, and what you see on your bill, is that

kW reflects the rate of electricity you use

, and kWh indicates the amount of electricity you use.

How many kWh is 30kw?

How many kWh per day is normal?

According to the EIA, in 2017, the average annual electricity consumption for a U.S. residential home customer was 10,399 kilowatt hours (kWh), an average of 867 kWh per month. That means the average household electricity consumption kWh per day is

28.9 kWh

(867 kWh / 30 days).
