Understand how to convert BTU/h to Watts and how the conversion from BTU (British thermal unit) to joule works. Learn what cooling power is and why using a conversion table is not enough. BTU stands for British thermal unit and is a measure of energy, like Joule. Watts, which is joule/second, is compatible with BTU/hour, as explained in the video. You will understand why the electrical power of a 10,000 BTU/h air conditioner is much lower than the cooling power calculated when performing the energy conversion. Among the objectives of this video, we highlight: Conceptualization of units for quantities such as energy and power. Conceptualization of terms such as refrigeration, energy transport, cooling power and electrical power. The conversion from BTU to Watt and its implications. We address the following items throughout this video: It is very common among electrical professionals to have doubts about the issue of converting BTU to Watt. BTU is a unit of energy and Watt is a unit of power; there is no direct conversion between them. In air conditioning, the correct unit is to use the BTU/h unit, which is a power unit. In this way, it is possible to convert BTU/h to Watt, since both are power. Presentation of the formulas and equivalences necessary for the conversion of BTU/h to Watt. Example of this conversion using the formula and equivalence. The power found in this conversion is not the power used for sizing electrical circuits for air conditioning and temperature converters. Difference between refrigeration power and electrical power Concepts about refrigeration. Parts highlighted in this video: 00:30 - The power conversion for air conditioning is generally used for sizing electrical circuits for these devices. 01:18 - It is important to understand that there are different types of power, such as electrical power and refrigeration power for devices. 02:16 - After time, temperature is the most measured quantity in the world. There are several methods for manipulating temperature, such as temperature controllers. 03:23 - For a correct conversion of units, it is important to know how to handle and correctly understand the multiples and submultiples of electrical units. 04:13 - Ohm's law is fundamental in the study of electricity, including electrical power. 05:10 - Refrigerators and air conditioners are driven by a compressor. Understanding these compressor drive circuits is a great complement to the study of refrigeration. 06:16 - Some types of refrigeration equipment have a three-phase motor as their main part. To calculate the nominal current of a three-phase motor, some variables must be taken into account. 07:17 - A major concern today is the consumption of refrigeration equipment such as refrigerators. 08:53 - To save money, you need to understand how electricity is charged.
