What is J per second?

Power is a measure of the rate of doing work (or using energy) in relation to time. The SI unit of power is the watt [symbol W] which is a rate of 1 joule per second.

Is HP a unit of power?

Horsepower, the common unit of power; i.e., the rate at which work is done. The electrical equivalent of one horsepower is 746 watts in the International System of Units (SI), and the heat equivalent is 2,545 BTU (British Thermal Units) per hour.

Is 1 HP equal to a horse?

Power of a horse Although it may seem safe to assume that one horsepower is the output a horse is capable of creating at any one time, that is incorrect. In fact, the maximum output of a horse can be up to 15 horsepower, and the maximum output of a human is a bit more than a single horsepower.

Is kW same as HP?

To convert kilowatts to horsepower, we multiply the number of kilowatts by 1.34. The result is that 80 kilowatts is roughly equivalent to 107 horsepower.

How is HP calculated?

Power = (Force x Distance) / Time For electric motors, power or horsepower can be calculated from the torque and speed. For example, if you have a motor rated for 3,000 RPM and 6 in-lbf then the horsepower is calculated below.

How much is a ton of cooling?

One Ton of cooling is the amount of heat needed to melt 2000 pounds of ice in 24 hours.

What is a nominal ton?

Product capacities are called out in terms of nominal tons. A nominal cooling tower ton is defined as the capability to cool 3 GPM (0.19 lbs) of water from a 95ºF (35.0ºC) entering water temperature to an 85ºF (29.4ºC) leaving water temperature at a 78ºF (25.6ºC) entering wet-bulb temperature.

What is nominal capacity in HVAC?

Nominal capacity and actual capacity This is the number that you will find on your product or one that a sales manager will use while telling you the AC capacity and features. But it does not mean that 3 ton, for instance is the actual cooling capacity of the air conditioner.

What is nominal heating capacity?

The nominal capacity of a tower is the heat load achievable at a certain set of design criteria as set by the cooling tower manufacturer. For example a tower could have a nominal capacity of 101 Tonnes, based on a set of design conditions 35degC HWT, 25.9degC CWT and 25.5degC WBT and a flow rate of . 681 m3/hr per ton.

What is nominal capacity of chiller?

Nominal tons are often thought of as being at AHRI standard conditions, which for an air-cooled chiller are 44˚F leaving water temperature with 10˚F delta T and 95˚F ambient outdoor temperature. The thing to remember is that operating conditions matter when assessing the size chiller needed for a building or process.

How many GPM are in a ton?

2.4 GPM

How do you calculate chiller TR?

Calculate tons of cooling capacity Tons = BTU/hr. ÷ 12,000. Oversize the chiller by 20% Ideal Size in Tons = Tons x 1.2. You have the ideal size for your needs.

What is cooling capacity in watts?

Cooling capacity is the measurement of a cooling system and its ability to remove heat from a space. SI units are watts (W). They can also be described in tons to signal how much water at X temperature can be frozen in X amount of time. ‘BTUs per hour’ signify how much heat per hour a unit can dissolve from the air.

How do you calculate cooling capacity of Watts?

The above equation can also be used to calculate the cooling capacity for different conditions….Determining How Much Cooling Capacity You Need

1. W = average cooling power (W)
2. V = total system liquid volume (L)
3. T = temperature difference (°C)
4. K = liquid heat capacity (J/L/°C)

What is a good cooling capacity?

The required cooling capacity for a room air conditioner depends on the size of the room being cooled — room air conditioners generally have cooling capacities that range from 5,500 Btu per hour to 14,000 Btu per hour. A common rating term for air conditioning size is the “ton,” which is 12,000 Btu per hour.

What is the best EER rating?

12 EER rating

Is 11.3 EER good?

Generally, an EER of 12 or above is considered energy efficient, however, when comparing two models, the one with the higher EER is more energy efficient regardless of whether or not it is above 12.

How can I reduce my electric bill with AC?

Here are six tips you can follow:

1. Set the Right Default Temperature.
2. Keep it at 24 °C, Instead of 18 °C.
3. Sealed Rooms & Shut Devices Save Electricity.
4. Switch on and Switch off to Save Electricity.
