What is mechanical cooling?

Mechanical cooling is one method for removing heat from where it does not want and releases elsewhere. The vast majority of domestic refrigerators, freezers and air conditioning use the mechanical cooling cycle to induce cooling. There are other, non -technical methods used to produce cooling, but their use is usually limited to specialized or industrial applications. The fluid absorbs heat in a space to be cooled and transfers it where it is less undesirable. The whole cycle relies on several components and laws of physics to reduce the temperature of the area.

The mechanical aspect of the cycle begins with a compressor, a combined electric motor and a pump. There is low pressure in the compressor, the gaseous refrigerant pressed on a significantly reduced volume. This compression increases the temperature of the refrigerant and Pressure and pushes it into another component, into the capacitor. The capacitor is only a hose coil through which air can flow. In the capacitor, it releases high pressure/high temperature gas and becomes liquidou.

You often feel the heat discarded by a capacitor on the back of the refrigerator for the household or from the outdoor coil components of the central air conditioning. The discarded heat was originally absorbed by refrigerant in the air -conditioned space. Now the refrigerant disposal flows through the capacitor because the compressor keeps the pressure behind it.

The next stop is a measuring device that can be a mechanical valve or just a tube of a small diameter, one of which the soul of the refrigerant. The liquid refrigerant passes through the measuring device to another coil called evaporator. Here, its pressure drops rapidly and the coolant of Prosíins brews at a temperature that is not usually associated with cooking: approximately zero degree Fahrenheit (minus 18 Celsius) in a typical household freezer. This low -temperature cooking is in fact the absorption of heat refrigerant. The thermally loaded, gaseous refrigerant flows back into the compressor and the cycle is not repeated until the thermostat is met.

The mechanical cooling cycle breaks into four phases: compression, condensation, measurement and evaporation. It flows into the evaporator and the capacitor, thereby both coils of types of heat exchangers. Mechanical cooling is not necessarily the most effective or non -phenomenon of cooling, but its simplicity practically ensures that it will be the standard for the foreseeable future.
