## What is definition of refrigeration capacity?

the amount of heat removed from an object to be cooled per unit time by a refrigerating machine. Refrigerating capacity is measured in watts or in kilocalories per hour. The refrigerating capacities of present-day refrigerating machines range from several hundred watts to ten or more megawatts. …

## What is refrigeration capacity formula?

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.

**What is meant by TR?**

Ton of Refrigeration (TR): Ton of Refrigeration (abbreviated as TR) is an important historical unit of refrigeration capacity. Originally 1 TR was defined as the rate of heat transfer required to make 1 short ton (2000 lbs) of ice per day from water at 0oC.

### What is refrigeration effect and refrigeration capacity?

Since the refrigeration effect is produced during phase change, large amount of heat (latent heat) can be transferred per kilogram of refrigerant at a near constant temperature. Hence, the required mass flow rates for a given refrigeration capacity will be much smaller compared to a gas cycle.

### What is meant by 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.

**How do you calculate TR?**

Total revenue is the price of an item multiplied by the number of units sold: TR = P x Qd.

## How do you calculate TR for refrigeration?

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.) of ice in 24 hours….Converting between Btu/h and Tons of Refrigeration.

Btu/h | Refrigeration Ton | kW |
---|---|---|

60000 | 5 | 17.6 |

## What is TR capacity?

A ton of refrigeration (TR) is a unit of heat extraction capacity of the refrigeration or cooling equipment. 1 TR is approximately equal to 12000 BTU or 3024 Kcal/hr of energy/heat load. The heat of fusion of water is about 335 KJ/kg or 80.01 kCal/kg. 1 short ton is equal to 2000 lb or 907 kg.

**What is TR of chiller?**

### 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.

### What are the units of refrigeration capacity?

The refrigeration capacity of a refrigeration system is the product of the evaporators’ enthalpy rise and the evaporators’ mass flow rate. The measured capacity of refrigeration is often dimensioned in the unit of kW or BTU/h. Domestic and commercial refrigerators may be rated in kJ/s, or Btu/h of cooling.

**What is the refrigeration capacity of domestic refrigerator?**

A large domestic refrigerator stands as tall as a person and may be about 1 m wide with a capacity of 600 L . Refrigerators and freezers may be free-standing, or built into a kitchen. The refrigerator allows the modern household to keep food fresh for longer than before.

## How many BTU per ton of cooling?

One Ton of Cooling is equal to 12,000 BTU/h. A condenser unit that can continuously cool at 12,000 BTU per hour has a 1 ton capacity. According to Dr-Fix-It, the name comes from the fact that it takes 288,000 BTU to melt one ton of ice at 32 °F to water at 32 °F in 24 hours, which is 12,000 BTU per hour.

## How many CFM in a ton of cooling?

Air quantities (cfm): 400 cfm per ton of cooling is needed for normal comfort applications, 500 cfm per ton of cooling for heat pump and high sensible heat applications, and 350 cfm per ton of cooling for high latent heat applications.
