Convert Metric Horsepower (PS) to Tons of Refrigeration (TR)
Understanding the conversion from Metric Horsepower (PS) to Tons of Refrigeration (TR) is crucial in various industries. The conversion factor is 1 PS = 0.209136 TR, making it easier to determine cooling capacities in refrigeration systems.
0.209136
≈ 13/64 TR
Formula: TR = PS × 0.209136
Conversion Formula
TR = PS × 0.209136
Reverse: PS = TR × 4.78158
Quick mental math: To estimate, remember that 1 PS is roughly 0.2 TR, so you can quickly deduce that 10 PS is about 2 TR.
Conversion Examples
1 PS × 0.209136 =
0.209 TR
1 Metric Horsepower = 0.209 Tons of Refrigeration
5 PS × 0.209136 =
1.046 TR
5 Metric Horsepower = 1.046 Tons of Refrigeration
10 PS × 0.209136 =
2.091 TR
10 Metric Horsepower = 2.091 Tons of Refrigeration
25 PS × 0.209136 =
5.228 TR
25 Metric Horsepower = 5.228 Tons of Refrigeration
50 PS × 0.209136 =
10.457 TR
50 Metric Horsepower = 10.457 Tons of Refrigeration
100 PS × 0.209136 =
20.914 TR
100 Metric Horsepower = 20.914 Tons of Refrigeration

Unit Definitions
What is a Metric Horsepower (PS)?
Metric (SI)Europe, Japan
Metric Horsepower (PS) is a unit of power commonly used in Europe and other parts of the world to describe the output of engines and motors.
History
The term 'horsepower' was coined by James Watt in the late 18th century to compare the output of steam engines with the work done by draft horses. The metric horsepower was later defined to create a consistent measurement in metric systems.
Current Use
Today, PS is widely used in automotive and engineering specifications, particularly in European countries, for measuring engine power.
What is a Ton of Refrigeration (TR)?
ImperialUnited States
A Ton of Refrigeration (TR) is a unit of measurement used to express the cooling capacity of refrigeration systems.
History
The term originated from the amount of heat absorbed by one ton of ice melting in a 24-hour period, which is equivalent to 12,000 BTUs per hour. This measurement has been standardized for use in modern refrigeration.
Current Use
TR is commonly used in the HVAC and refrigeration industries to specify the cooling capacity of systems, particularly for commercial and industrial applications.
Frequently Asked Questions
How many Tons of Refrigeration are needed for a typical air conditioning unit?
A standard residential air conditioning unit may require around 3-5 tons of refrigeration. For example, if you have a unit rated at 10 PS, using the conversion factor, you would find that it equates to approximately 2.09136 TR. This means that the unit can effectively cool a space that requires about 2.1 tons of cooling capacity.
What is the role of Tons of Refrigeration in commercial refrigeration systems?
In commercial refrigeration systems, such as those found in supermarkets, the cooling requirements can be significant. For instance, if a supermarket uses a system rated at 50 PS, converting that to tons gives you about 10.4568 TR. This measurement is essential for ensuring that the refrigeration system can maintain optimal temperatures for perishable goods.
How does Metric Horsepower relate to energy consumption in fitness equipment?
In fitness equipment, such as treadmills, understanding the metric horsepower is important for energy efficiency. If a treadmill has a motor rated at 2 PS, it translates to approximately 0.418272 TR. Knowing this helps users gauge the power consumption and efficiency of their machines during workouts.
How can I apply these conversions in cooking and food preservation?
When determining the cooling needs for food preservation, knowing how to convert PS to TR can be beneficial. For instance, if you have a walk-in cooler with a cooling capacity of 25 PS, it equates to about 5.2284 TR. This information is crucial for chefs and restaurant owners to ensure that their refrigeration systems operate efficiently.
What kind of machinery uses PS and TR in their specifications?
Machinery such as industrial chillers or commercial HVAC systems often specify their capacity in PS and TR. For example, a chiller rated at 100 PS would translate to about 20.9136 TR. This conversion helps engineers and technicians select the right equipment based on the cooling requirements of a facility.
