Explain How Major Heating and Cooling Appliances May Work in Opposition

Question

Examlex · Accepted Answer

The Answer is Take for example a refrigerator and a freezer operating in an air conditioned home during the hot days of summer.Both appliances use refrigeration units driven by electric motors to extract heat from their interiors and keep them at the required low temperatures.But the excess heat removed is then vented directly into the kitchen where the appliances are located.This heat warms the room and makes the air conditioning system work harder (consuming more power) to keep the room temperature at a comfortable level.A cooking appliance such as a stove, grill or toaster also adds heat to the kitchen which the air conditioning system must then overcome.Similarly, a hair dryer can easily raise the temperature in a bathroom by 15 degrees or more, again making the air conditioning work harder to overcome the excess heat.
