Definitions

  • the present invention relates to a refrigerating apparatus, particularly an energy-saving refrigerator.
  • the design for energy-saving in refrigerators could be carried out from 2 main aspects.
  • An effective solution is to increase the COP of the compressor , or optimize the evaporators in the freezing chamber. For example ,sealing the evaporators, or adding heat sink fin on the evaporation pipes.
  • the present invention provide an refrigerator with lower cost, energy-saving and easy processed.
  • An energy-saving refrigerator which comprises an inner shell and multiple layers of inner chamber evaporators arranged inside a chamber of the inner shell, wherein multiple outer chamber evaporators are arranged on the surfaces of the four sides of outside the inner shell.
  • the outer chamber evaporators comprise multiple evaporation pipes and heat transmission plates, wherein the heat transmission plates are arranged between the evaporation pipes and the inner shell.
  • the outer chamber evaporators comprise multiple evaporation pipes and multiple aluminium foils, wherein the aluminium foils cover on the surfaces of the evaporation pipes and the inner shell.
  • the advantageous effects is of the present invention is: due to the surfaces of four sides outside the inner shell are arranged with the outer chamber evaporators, when the refrigerator starts up, the inner chamber evaporators in the chamber of the inner shell coordinate with the outer chamber evaporators outside the inner shell to form a three dimensional cool air curtain, which greatly enlarges the evaporation area and make the cool air alternately transfer, thus the refrigeration is faster and stronger; meanwhile, due to the effect of the outer chamber evaporators, the high temperature of the external environment could not affect the temperature recover of the load in the case when the refrigerator stops, further when the refrigerator starts up again, the refrigerating fluid quickly carries away the heat absorbed by the outer chamber evaporators, thus ideal heat insulation could be achieved by properly designing the scale of time interval of starting and stopping; the present design satisfies the demands for both cooling and heat insulation, thus the refrigerator is more energy-saving, and the temperature in the chamber is equalized, which is good for keeping the food fresh, also the present design simplify the structure, which make the fabrication
  • an energy-saving refrigerator comprises an inner shell (1) and multiple layers of inner chamber evaporators (2) which are arranged inside a chamber of the inner shell (1), and multiple outer chamber evaporators (3) are arranged on the surfaces of four sides outside the inner shell (1) .
  • a single-cycle refrigeration system consists of the compressor ( 5 ), the condensator ( 6 ), the filter (7), the capillary (8), the inner chamber evaporators ( 2 ), the outer chamber evaporators ( 3 ), the evaporators of refrigerating chamber ( 4 ).
  • the refrigerating fluid out from the capillary ( 8 ) firstly pass by the inner chamber evaporators ( 2 ), the refrigeration rate is fast due to the inner chamber evaporators ( 2 ) directly contact with the loads, then the refrigerating fluid pass by the outer chamber evaporators ( 3 ), the inner chamber evaporators (2) in the chamber of the inner shell (1) coordinate with the outer chamber evaporators ( 3 ) outside the inner shell to form a three dimensional cool air curtain, which greatly enlarges the evaporation area and make the cool air alternately transfer, thus the refrigeration is faster and stronger, and the temperature in the chamber is more equalized, and it's good for keeping the food fresh; when the refrigerator stops, the temperature of the heat transmission plates ( 32 ) is below -30 °C, and the temperature of the loads inside the chamber of the inner shell ( 1 ) stay at -18 °C, which means the temperature of the heat transmission plate ( 32 ) is at least 12°C lower than that of the food, thus
  • the structure of the present design is simple, the fabrication is very easy to process, and the cost is lower, thus satisfying the demand for energy-saving in all people.
  • the outer chamber evaporators (3) comprise the evaporation pipes (31) and the heat transmission plates (32), wherein the heat transmission plates (32) are arranged between the evaporation pipes (31) and the inner shell (1), so that the heat transmission plate ( 32 ) could sufficiently contact with the inner shell ( 1 ), which is good for the refrigeration; in addition, the outer chamber evaporators ( 3 ) could be designed in another way, i.e.
  • the outer chamber evaporators ( 3 ) comprise the evaporation pipes ( 31 ) and the aluminium foils ( 33 ), wherein the evaporation pipes ( 31 ) is wound on the inner shell ( 1 ), and the aluminium foils ( 33 ) cover the evaporation pipes ( 31 ) and the inner shell ( 1 ), which could effectively apply the refrigeration.
  • the present invention is not limited to above modes of carrying out the utility model, any other ones that basically using the same means for the same technical effect should fall into the scope of protection of the present invention.
