pound foot per hour
- Definition: Pound foot per hour is a unit of measurement used to quantify the rate of heat transfer in thermal systems. It indicates how many pound-feet of heat energy are transferred in one hour.
- Symbol: The symbol for pound foot per hour is often represented as lb-ft/hr.
- Usage: This unit is commonly used in various engineering fields, particularly in HVAC (Heating, Ventilation, and Air Conditioning) systems, to measure the performance of heating and cooling equipment.
ton refrigeration
- Definition: Ton refrigeration is a unit used to denote the cooling capacity of refrigeration systems. It is defined based on the amount of heat required to melt one ton of ice in 24 hours.
- Symbol: The symbol for ton refrigeration is typically represented as TR.
- Usage: Ton refrigeration is widely used in the refrigeration and air conditioning industry to compare the cooling capacities of different systems and equipment.
Origin of the pound foot per hour
- The pound foot per hour originated from the imperial system of units, which has its roots in various historical measurements used in the United Kingdom and other countries. It combines the pound as a measure of weight and the foot as a measure of distance, reflecting its application in thermal energy calculations.
Origin of the ton refrigeration
- The concept of ton refrigeration was developed in the 19th century when ice was a primary means of cooling. The term “ton” was used to describe the amount of ice that could be melted over a 24-hour period, leading to the modern understanding of cooling capacity in refrigeration and air conditioning systems.
