In a refrigerator heat energy is brought out by a special method. To transfer heat from a colder object to a hot object we will have to expense mechanical energy. This mechanism is called a heat pump. As a result, the
Energy storage systems combining cooling, heating, and power have higher flexibility and overall energy efficiency than standalone systems. However, achieving a large cooling-to-power ratio in direct-refrigeration systems without a phase change and in indirect refrigeration systems driven by heat is difficult, limiting the energy output of the system.

In refrigeration, this principle ensures the balance of energy input and output. Second Law of Thermodynamics: It dictates that heat naturally flows from a hotter body to a colder one. The refrigeration cycle defies this natural flow by using work (energy) to transfer heat from a colder area to a warmer area.

The main principles of the refrigeration process, or cycle, are: the absorption of the amount of heat necessary for the change of state from a liquid to a vapor by evaporation, and the release of that amount of heat necessary for the change of state from a vapor back to the liquid by condensation.
For the fan, however, energy input is applied. The total electrical power input f the refrigeration system is composed of the electrical power for the compressor (including oil sump heater, fan etc.) and for the units that enable the transport of the fluids outside the refrigerant circuit (pumps, fans).
Try to answer the question again. Refrigeration is the process of removing heat from an area or a substance. It is usually done by an artificial means of lowering the temperature, such as by the use of ice or mechanical refrigeration, which is a mechanical system or apparatus, designed and constructed to transfer heat from one substance to another.
Ho and Yu used a linear regression method to find the optimal parameter by using cross-validation, and thus accordingly achieved an improvement in the cooling efficiency of the refrigeration unit, actual energy consumption declined 77.3 %, compared with the predicted of 76.7 %.
In this context the heat removed from a cooled system is referred to as “generated refrigerating energy” QoN. It results from the integration of the refrigerating capacity over the time period Dt = t2 t1. The input energy is technical work Wt to drive the whole system
