Definitions

  • the invention relates to an evaporator with cooling effect, a condenser which releases the heat out during the refrigeration cycle and solving the problems about cooling and power save in the freezers of household refrigerators comprising a compressor which allows the compression of the refrigerant to the condenser pressure.
  • the invention especially relates to prolonging the duration of temperature rise by using a mobile phase-change material (PCM) inside a lidded division located in the freezers of said refrigerators, and saving power by reducing the working frequency of the compressor, in addition to this, the conservation of the heat of the food inside the carrying bag by locating the said phase-change material inside a specially insulated carrying bag.
  • PCM mobile phase-change material
  • coolers that enable foods to be preserved for a long time by keeping them cool are using vapour compression method as the cooling system.
  • evaporator, condenser, compressor and refrigerant (refrigerant gas) circulating inside this system are used.
  • the evaporator vaporises the refrigerant with the heat it received from the cooling cabin.
  • the efficiency of the coolers are directly related to the present heat insulation, internal and ambient temperature difference, the span of opening the door of the cooler (frequency of usage) etc. While efficient coolers, with compressor working for longer periods (longer period of heat rising) save power, the ones with low efficiency work more frequently (shorter period of heat rising) causing power loss.
  • the efficiency of the cooling device is in direct proportion to preserving the low temperature created inside the cooling cabins. Preservation of the heat is one of the biggest problems today and there are different techniques and methods for trying to overcome it. In some of these methods, heat exchange between the cooling cabin and the external environment is lessened by using different insulating materials. However, considering there is no such thing as perfect insulation, these methods are not sufficient for improving the cooling performance.
  • Phase-change materials are materials characterized in taking or giving high amounts of energy in phase transitions happening at a certain temperature such as solid to liquid or liquid to solid. The material at a temperature different from the phase change temperature, stores or releases out the heat in a conventional way. The heat which causes the material to change phase is called 'latent heat' or 'phase change heat'.
  • Phase change material that change phase in a certain heat can be used to store high or low temperature levels. Some other materials also have high latent heat like phase change materials, however the alteration in their physical structure during the phase change makes them difficult to use.
  • the invention influenced by the current art, aims to solve the above mentioned problems.
  • the present invention relates to meeting the above mentioned needs, eliminating all the disadvantages and bringing in additional advantages, lengthening the temperature rise time by placing mobile phase-change material inside the lidded sections located in the doors of household refrigerators, increasing the efficiency and lessening the consumption of energy.
  • the object of the invention is to store low temperature with the help of the phase-change material located inside the lidded section placed in the door of the freezer and by lengthening the temperature rise time lessening the working frequency of the compressor. Hence, the compressor saves power by working less and resting longer.
  • Another object of the invention is to preserve the low temperature inside the cabin in the cases like power cuts which disrupts the working of the refrigerator by locating phase-change material located inside the lidded section placed in the door of the freezer.
  • Another object of the invention is by placing the phase-change material located inside the lidded section placed in the door of the freezer with the help of an insulated carrying bag like a bag to carry the products that need low temperature. Thanks to the phase-change material located in the lidded section in the freezer, space is saved.
  • a cooling system which comprises,
  • the cooling system according to the invention consists of household refrigerator (100), insulated carrying bag (9) and phase change material (8).
  • the function of the elements located inside and on the household refrigerator (100) is: an evaporator (1) connected to the freezer (4) and cooler (5) in the refrigerator (100), absorbs the heat there and then it makes the refrigerant it comprises transfer into gas phase. Then the refrigerant moves to the condenser (2), gets compressed by high pressure providing compressor (3) and transforms into liquid phase again and releases its heat to outer environment. The liquid refrigerant goes back to the evaporator (1). Thanks to the heat cycle created in this way, the cooling effect is created inside the freezer (4) and the cooler (5).
  • the -18°C inside the freezer(4) and the 5°C low heat inside the cooler (5) are insulated from the outer environment thanks to the polyurethane insulation (6).
  • the cooling performance is directly related to the power of the compressor (3) and the efficiency of the insulation material.
  • phase change material (8) can store low level heat thanks to its structure. By repeatedly giving the low level heat it acquires from the evaporator (1) inside the freezer (4) to the freezer (4) during the stopped time of the compressor (3), it lengthens the temperature rise time, hence the stopped time. Thus, power save is achieved. Moreover, with the reduction of the frequency of compressor's (3) on/off period, the said compressor's (3) economic life increases. This situation also increases the economic life of the refrigerator (100).
  • Phase-change material (8) is placed inside the lidded (71) section (7) located on the door of the freezer (4). This way, it doesn't occupy space in the freezer (4) and the view is improved. Thanks to the lid (71) present in said section (7), the phase change material (8) can be disassembled. In addition, by placing the phase change material (8) inside the insulated carrying bag (9), it can be carried anywhere without losing temperature. The carrying bag (9) used with phase change material (8), in the places without cooling means, cools the foods and beverages and this way makes them stay cool for a longer time and makes them easily carried from one place to another. Thanks to the lidded (71) section (7) inside the freezer (4), the consumer can easily put the phase change material (8) in its place, and make it ready for the next use.
