The History of the Refrigerator and Freezershttp://inventors.about.com/library/inventors/blrefrigerator.htm
A refrigerator because it uses cooler air. The reason an oven isn't, is because the generator in a pven has gases & can not be used for oxygen. A refrigerator can because it uses air to keep food cool...
To keep thing cool / cold.
Yes, a refrigerator uses an electromagnet in its operation. The compressor in a refrigerator contains an electric motor that drives a pump, which circulates the refrigerant through the system. The motor operates using an electromagnet that converts electrical energy into mechanical energy to compress the refrigerant. This process is essential for the refrigerator to maintain its cooling function.
The compressor in a refrigerator uses electricity to compress the refrigerant gas, which causes it to release heat and transfer energy from the inside to the outside of the refrigerator.
A 100 watt light bulb draws a little less than one amp. A refrigerator draws much more when compressor is running. The duty cycle of the light and refrigerator will ultimately determine which uses more power on a Kilowatt Hour basis.
A RV absorption refrigerator uses a thermistor as a thermostat. The thermistor is moved up or down to regulate the refrigerator temperature.
The refrigerator typically uses more energy than the dishwasher or dryer because it runs continuously to keep the food inside cool. Dishwashers and dryers consume a lot of energy during their operation, but they are not constantly running like a refrigerator.
a heat pump that uses work to move heat
On average, a 1.7 cu.ft compact refrigerator typically uses around 1-2 amps when running. However, depending on the specific model and manufacturer, this number may vary slightly. It is recommended to check the product specifications or the label on the refrigerator for the exact amperage information.
