Jan 2, 2022 · Animation: The basic idea of what's sometimes called mechanical refrigeration. Inside a refrigerator (1), we change a liquid into a gas to pick up heat from inside the cooling cabinet (2), pump it outside the machine, and then change it back into a liquid to release its heat there (3).
Listen Now: How Do Iceboxes Work? 0:00. Back when most folks relied on an icebox to cool food, a block of ice was a precious commodity. If you put hot food in the icebox, the ice might melt. And ...
The compressor does work on the refrigeration system (consumes energy). It raises the pressure, temperature and enthalpy of the refrigerant by compressing the saturated gas, in an isentropic process, to a superheated gas (i.e. entropy is constant – reversible process). The condenser is between points 3 and 4. It cools the refrigerant until it ...
The left side of the circuit (including the cooling coils inside the refrigerator) is at low temperature and low pressure; the right side (including the condenser coils outside the refrigerator) is at high temperature and high pressure. Ordinarily, both sides contain liquid and vapor in phase equilibrium.
A refrigerator works by using the vapor compression refrigeration cycle to remove heat from the interior of the appliance and transfer it to the surrounding environment. By effectively moving heat energy to the outside, the transfer cools the space inside. This process relies on the principles of thermodynamics and the properties of ...
