Refrigerators | ☑ Energy Efficiency ☐ Renewable Energy ☐ Alternative Methodology |
Description | A refrigerator (colloquially fridge) is a common household appliance that consists of a thermally insulated compartment and a heat pump (mechanical, electronic, or chemical) that transfers heat from the inside of the fridge to its external environment so that the inside of the fridge is cooled to a temperature below the ambient temperature of the room. Refrigeration is an essential food storage technique in developed countries. Lower temperatures in a confined volume lowers the reproduction rate of bacteria, so the refrigerator reduces the rate of spoilage.
Electrical refrigerators are available for low voltage power supply (12 or 24 VDC), designed for the decentralized application with photovoltaics. | ||||||||||||||||||||||||||||
