Step 3: Prepare the Spreadsheet. In this tutorial, we will create a very simple macro to change the color, size and boldness of text. In your spreadsheet, type in some text in any of the cells. We will later record a macro to change the formatting of this text.
The average cooling capacity of a dorm fridge is somewhere around 150 BTU/hr, that is, it is capable of moving 150 BTUs of heat in 1 hour, regardless of how efficient (or inefficient) it is in terms of energy usage.
By a moderator at Refrigeration Engineer: 1  16 EER means 16 Btu/hr of cooling for every watt of power used. 2  1 watt = 3.412 Btu/hr, so. 3  16 EER unit provides 16  3.412 = 4.69 watts of cooling for every watt of power used. This is the coefficient of performance (COP). 4  1 ton refrigeration = 4.712 horsepower, electric.
