Refrigerators 700-2000 watts
Like air conditioners, refrigerators too have air compressors, and hence utilize a lot of energy. Refrigerators are never switched off, except during defrosting or for cleaning. Saving power in this case can be difficult, but you can follow a few steps to increase power efficiency. When the refrigerator door is opened or kept open for a longer period, the cool air escapes causing a rise in the temperature inside. This causes the compressor to work continuously – without tripping – to keep the refrigerator cool. If the door is kept closed, the temperature remains constant without rising. Therefore, the most important – although cliché – tip is to keep the refrigerator door tightly closed.
