Refrigerator that uses a heat source
Absorption refrigerator
An absorption refrigerator is a refrigerator that uses a heat source to provide the energy needed to drive the cooling process. Solar energy, burning oil, waste heat from factories, and district heating systems are examples of heat sources that can be used. An absorption refrigerator uses two coolants, the first coolant performing evaporative cooling before being absorbed into the second coolant. Heat is then needed to reset the two coolants to their initial states. Absorption refrigerators are commonly used in recreational vehicles (RVs), campers, and caravans because the heat required to power them can be provided by either a propane fuel burner, a low-voltage DC electric heater (from a battery or vehicle electrical system) or a mains-powered electric heater. Absorption refrigerators can also be used to air-condition buildings using the waste heat from a gas turbine or water heater in the building. Using waste heat from a gas turbine makes the turbine very efficient because it first...
