Thermodynamic heat exchangers or refrigeration cycles are perhaps the most complex and conceptual model for refrigeration, air conditioning and heating systems. A heat exchanger is a physical system which enables for the transportation of heat from a lower temperature in a liquid to a higher temperature in a solid. This transport of heat between liquids and gases occurs because of the kinetic energy (energy being motion) between the fluids and the gas atoms. The concept is based on the work of J.C. Watson, who came up with the original assumption that a heat exchange cycle can be a self-regulating device.

In a standard refrigeration cycle, the gas (the hot fluid) flows through the compressor and passes through the condenser where it is condensed into a liquid (the cold liquid). One main difference between this and other types of refrigeration cycle is the way the gas and the liquid are heated. The gas heats up before being compressed and pushed out through the condenser coil. As this hot fluid passes through the coil, the coil absorbs the excess heat, closing the loop. The refrigerant gas is then passed through the expansion vessel and the end of the refrigeration cycle is reached when the refrigerant is cooled. The end result is that the chilled liquid is then released into the storage compartment or the cooler. Now, in this model of the refrigeration cycle, there is only one compressor instead of three. Since the compressor can only hold so much heat, it cannot continue to run at low temperatures indefinitely. Therefore, as temperatures rise, the compressor must kick on and start pushing heat out into the colder spaces of the system. This is why the refrigeration cycle needs to be periodically shut down and checked for build-up. If you have a well-insulated system, this can be done manually using a flashlight. If not, you will need a device such as a refrigerant leak detector, built-in thermostat, or a low amperage motor. It is important to set these parameters according to manufacturer recommendations. After the refrigerant has been removed, a new batch of refrigerant must be mixed in to replace all the evaporated refrigerant. In the meantime, you can run your fridge to its full capacity and use the freezer space to thaw some foods. At the same time, you can defrost frozen meats. While running the refrigerator to its full temperature will keep the condenser coil working, the refrigeration cycle should work as long as possible, without interrupting it. Check out this post that has expounded on the topic: https://en.wikipedia.org/wiki/Refrigeration#History. How long a refrigerator will stay properly cooled depends on how well the cooling system is designed so that the condenser and compressor are not obstructed. The most common cause of jamming in condensers and compressors is excessive moisture dripping into them, which can be cleaned up by wiping with a damp cloth. Your ice machine's cooling system is designed so that the compressor and condenser do not become clogged. If they become clogged, they will not cool the inside of your refrigerator. This may cause the cooling system to work harder than needed, which causes the ice machine to work even harder, and eventually damage your appliance. By regularly cleaning your refrigerator and by running any necessary maintenance checks on it, you can avoid costly damage to your ice machine.
