Community work is a specific method of social work. It supports people in the establishment of agency and political participation, taking into account different dimensions of marginalization of all people who stand in territorial relations to each other, form a functional context or are defined or defined by categorical belonging cf. Eberlei et al. Social work in the community is based on a scientific, professional and ethical framework of justification, which includes a human rights mandate cf. Martin Korsch 52 , the broad approval of racist resentments cf. Decker et al.

Cooling capacity is the measure of a cooling system's ability to remove heat. As the target temperature of the refrigerator approaches ambient temperature, without exceeding it, the refrigeration capacity increases thus increasing the refrigerator's COP. The SI unit is watt W. Another unit common in non-metric regions or sectors is the ton of refrigeration , which describes the amount of water at freezing temperature that can be frozen in 24 hours, equivalent to 3.

The therm symbol, thm is a non- SI unit of heat energy equal to , British thermal units BTU , [1] and approximately megajoules , One therm is the energy content of approximately cubic feet 2. However, the BTU is not standardised worldwide, with slightly different values in the EU, UK, and United States, meaning that the energy content of the therm also varies by territory. Natural gas meters measure volume and not energy content, and given that the energy density varies with the mix of hydrocarbons in the natural gas, a "therm factor" is used by natural gas companies to convert the volume of gas used to its heat equivalent, usually being expressed in units of "therms per CCF" CCF is an abbreviation for cubic feet. Higher than average concentration of ethane , propane or butane will increase the therm factor and the inclusion of non-flammable impurities, such as carbon dioxide or nitrogen will reduce it. The Wobbe Index of a fuel gas is also sometimes used to quantify the amount of heat per unit volume burnt.

It is defined as 1 joule per second and is used to quantify the rate of energy transfer. It was first proposed in by William Siemens who defined it as "the power conveyed by a current of an Ampere through the difference of potential of a Volt. In , the "international" definitions were defined, with Siemens' definition being adopted as the international watt. These were used until when the General Conference on Weights and Measures re-defined the watt to absolute units, using only mass, time, and length. The absolute watt was adopted as the SI unit of power in Current use: As the SI derived unit of power, the watt in all its multiples and submultiples is used in many applications worldwide from radio transmission to use in the electric power industry. This unit is often abbreviated as simply "Btu," which is the same abbreviation used for British thermal units, a measurement of heat. One watt, the International System of Units derived unit of power, is equal to approximately 3.

This unit is often abbreviated as simply "Btu," which is the same abbreviation used for British thermal units, a measurement of heat. One watt, the International System of Units derived unit of power, is equal to approximately 3. It has a number of different definitions all of which equate to approximately 1, joules. Current use: The British thermal unit per hour is not a widely used unit. It is defined as 1 joule per second and is used to quantify the rate of energy transfer. It was first proposed in by William Siemens who defined it as "the power conveyed by a current of an Ampere through the difference of potential of a Volt. In , the "international" definitions were defined, with Siemens' definition being adopted as the international watt. These were used until when the General Conference on Weights and Measures re-defined the watt to absolute units, using only mass, time, and length.

Air conditioners extract heat from indoor air and move it outdoors, which is the same as saying that air conditioners move energy. The BTU rating indicates the power of the unit, also referred to as the size of the unit.
