How do you calculate cooling capacity?

How do you calculate cooling capacity?

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.

What is TR capacity in cooling towers?

Some commercial and industrial refrigeration systems are rated in Tons of Refrigeration (TR, tons). A ton is the amount of heat removed by an air conditioning system that would melt 1 ton (2000 lbs.)…Converting between Btu/h and Tons of Refrigeration.

Btu/h Refrigeration Ton kW
54000 4 1/2 15.8
60000 5 17.6

How do you calculate gpm for a cooling tower?

Heat Load (BTU/Hr) = GPM X 500 X ° Range of cooling, or rearranged to determine the design flow rate. GPM = Heat Load (BTU/Hr) = 6,250,000 Btu/Hr = 835 gpm 500 X ° Range of cooling 500 x 15° R Now you can make your cooling tower selection based on 835 gpm, cooling from 98°F to 83°F @ a design 76°F Twb.

How do you calculate TR?

One ton of refrigeration is equal to 3024 kilo-calories per hour. This is 12,000 BTU/ h divided by 2

How many HP is 40 sqm?

TIP 1: Match your aircon horsepower (HP) to the size of your room

Room Size Aircon Horsepower (HP)
12 to 17 sq. m 0.75 HP
18 to 22 sq. m 1.0 HP
23 to 27 sq. m 1.5 HP
28 to 40 sq. m 2.0 HP

How many kW is 1 ton?

3.517 kW
Popular Answers (1) cooling capacity of 1 ton is equal to 3.517 kW of power.

What are the two types of cooling towers?

There are three main types of cooling towers that are defined by how water or air pass through them. These types include crossflow, counterflow, and hyperbolic. There are also two varieties classified solely on airflow, known as induced draft and passive draft cooling towers.

Why is 2.4 gpm a ton?

The 2.4gpm evaporator flowrate and the 3gpm condenser flowrate per ton thumbrules come about due to the increase in heat energy sent to the condenser. The condenser must reject heat from two sources.

What is the formula to calculate GPM?

The formula to find GPM is 60 divided by the seconds it takes to fill a one-gallon container (60 / seconds = GPM). Example: The one-gallon container fills in 5 seconds, breakdown: 60 divided by 5 equals 12 gallons per minute.

What is the formula of Mr?

Marginal revenue (MR) is calculated by dividing the change in total revenue by the change in total output quantity. Therefore, we can look at each additional item sold as MR. For instance, a firm may sell 50 products for $500. If the 51st item sells for $6, then its MR is also $6.

How do you calculate MR and TR?

You can calculate AR by dividing your total revenue (TR) by your quantity sold:

  1. AR = TR/Q. Marginal Revenue vs.
  2. MR = ΔTR / ΔQ. AR = TR/Q.
  3. MR = ΔTR (1,045 – 1,000) / ΔQ (11 – 10) = 45.
  4. MR = ΔTR (1,080 – 1,045) / ΔQ (12 – 11) = 35.
  5. TR = P x Q.
  6. TR (500) = P (10) x Q (50)
  7. MR = ΔTR (549.45 – 500) / ΔQ (55 – 50) = 9.89.

How to calculate the capacity of a cooling tower?

Factors Affecting Cooling Towers Capacity 6. Choosing a Cooling Tower Type 7. Water Flow and Heat Transfer 8. NTU or KaV/L Calculation 9. Consideration of By-Pass Wall Water 10. Pressure Drops in Cooling Towers 11. Air Flow Arrangements 12. Motor Power Sizing 13. Water Evaporation 14.

How big is a 1 ton cooling tower?

A 1-ton chiller is equal to 12,000 British thermal units. This amount of heat could theoretically melt 1 ton of ice in 24 hours. A cooling tower’s job is to reduce the temperature of water through refrigeration. It is used in manufacturing, electrical-power generation and massive air-conditioning systems.

How to choose the right cooling tower for your home?

Move across to the CAPACITY MULTIPLIER FACTOR SECTION to the right-hand curve and stop at the intersection of the 10°Range line, and read the CAPACITY MULTIPLIER FACTOR, which is 1.0. To select the proper cooling tower for this application, multiply the 200 Nominal tons calculated, by the 1.0 CAPACITY FACTOR.

What is the purpose of a cooling tower?

A cooling tower’s job is to reduce the temperature of water through refrigeration. It is used in manufacturing, electrical-power generation and massive air-conditioning systems. Determine the water flow rate though the cooling tower.
