What is Cooling Cycle ?

Refrigeration Cycle can be described as; after a coolant which absorbs the heat, the temperature differences occurred by the spread. These temperature differences are actualized in a refrigerator.

Conversion Cycle can be described as;

After coolant fluid in low pressure is increased to high pressure by compressor, it is sent to condenser. Condensation occurs in condenser and sen to expansion valve, circulated here and turns into low pressure liquid. Hereby, refrigeration is acualized with the means of air cooler.

  • Condenser
  • Expansion valve (also seen as Reducing valve)
  • Air Cooler
  • Compressor

In these applications storage or living spaces are cooled by sending the heat from the low temperaturized source to high temperaturized environment.Normally heat moves from high temperature to low temperature. Because of this, isolation is bearing high importance in these applications. Regarding to this reason, isolation materials with low heat transmission coefficient are used. Most used one in today’s systems is polyurethane. Isolation, to protect the low temperature in cooled area, to decrease the required energy and power for reaching low temperature.Working principle of refrigeration cycle, as mathematically defined by Sadi Carnot in 1824 with a heat machine. Most general refrigeration systems, cycle based on phase alternation heat pump is used. At the same time, absorbed heat pumps are used in most applications.
