How is TR capacity calculated?
How is TR capacity calculated?
Use the formula Q = M X C X ΔT where:
- Q = heat load in British Thermal Units per Hour (BTUH)
- M = flow in Gallons per Hour (GPM)
- C = specific heat of the fluid.
- ΔT = temperature difference in degrees Fahrenheit.
- Q = 500 BTU per gallon per hour X 40 GPM x 12 ΔT = 240,000 BTU per hour.
How do you calculate refrigeration 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?
A ton of refrigeration (TR) is a unit of heat extraction capacity of the refrigeration or cooling equipment. Generally, TR is defined as the amount of heat transferred to freeze or melt 1 short ton of ice at 0 deg. C in 24 hours. 1 TR is approximately equal to 12000 BTU or 3024 Kcal/hr of energy/heat load.
What is TR in cooling capacity?
A ton of refrigeration (TR or TOR), also called a refrigeration ton (RT), is a unit of power used in some countries (especially in North America) to describe the heat-extraction capacity of refrigeration and air conditioning equipment.
How do you calculate TR on a cooling tower?
Multiply 500 times the water flow rate, times the temperature difference, divided by 12,000 or 500 x q x dt/12,000. The result is the tons of capacity of the cooling tower.
How do you calculate kW and TR?
In English terminology, 1 TR is 3024 KCal. Learn How the value of 3024 KCal or 3.517 KW derived…..!! One short ton = 2000 lb, Heat extracted = 2000 x 144/24 hr = 288000 Btu/24 hr = 12000 Btu/hr = 200 Btu/min, 1 ton refrigeration = 200 Btu/min = 3.517 kJ/s = 3.517 kW = 4.713 HP .
What is the formula of refrigerant?
ASHRAE Refrigerant Designations
| Number | Chemical Name | Chemical Formula |
|---|---|---|
| 124 | 2-chloro-1,1,1,2-tetrafluoroethane | CHClFCF 3 |
| 125 | pentafluoroethane | CHF 2CF 3 |
| 134a | 1,1,1,2-tetrafluoroethane | CH 2FCF 3 |
| 141b | 1,1-dichloro-1-fluoroethane | CH 3CCl 2F |
What does 1 tonne TR in refrigeration mean *?
Explanation: 1 Tonne Rating (TR) means that the capacity is such that it can convert 1 tonne of water to ice i.e. 0C in 24 hours.
What is the value of 1 ton of refrigeration?
A much less common definition is: 1 tonne of refrigeration is the rate of heat removal required to freeze a metric ton (1000 kg) of water at 0°C in 24 hours. Based on the heat of fusion being 333.55 kJ/kg, 1 tonne of refrigeration = 13,898 kJ/h = 3.861 kW.
How many BTU’s are in a ton?
12,000 BTU/hr
That number is generally rounded up to 12,000 BTU/hr. So, a one ton air conditioning unit has the capacity to cool up to 12,000 BTU/hr.
How many BTUs is a ton?
12,000 BTU
There’s a complicated mathematical formula involved in converting the weight of that ice into energy, but in the end a “ton” of air conditioning capacity represents roughly 12,000 BTU per hour.
