Description

Technical Field

[0001] The present invention belongs to the technical field of refrigeration equipment, and in particular relates to an integrated refrigeration system and a display-type commercial refrigerator. Background Art

[0002] Existing commercial display refrigerators suffer from the drawback of inefficient space utilization, influenced by the layout of the refrigeration system, particularly the evaporator. While integrating the refrigeration system and placing it behind the display refrigerator can increase the overall display area, this places high demands on the cooling and heat dissipation performance of the refrigeration system. Therefore, there is an urgent need to design an integrated refrigeration system that occupies a small space and provides excellent cooling and heat dissipation performance. Summary of the Invention

[0003] The present invention aims to solve the above technical problems and provides an integrated refrigeration system.

[0004] The present invention also provides a display-type commercial refrigerator using the above-mentioned integrated refrigeration system.

The bottom of the display commercial refrigerator is stepped, the high-step portion is located at the rear of the bottom of the display commercial refrigerator, and the low-step portion is located in front of the bottom of the display commercial refrigerator. Both the high-step portion and the low-step portion are open at both ends facing the outside of the display commercial refrigerator. The integrated refrigeration system includes a frame, which is arranged in the inner cavity of the high-step portion of the bottom of the display commercial refrigerator. The frame includes a lower support and an upper support. A compressor and a condenser are installed on the lower support. A compressor is installed in front of the compressor. There is a compressor fan, which is a blowing fan. A condenser fan is provided behind the condenser, and the condenser fan is an intake fan. External air enters from the end face of the low-order part, passes through the compressor fan and the compressor, as well as the condenser and the condenser fan, and is discharged from the end face of the high-order part; an evaporator is provided on the upper bracket, and an evaporator fan is provided behind the evaporator. The gas in the display commercial refrigerator passes through the evaporator and the evaporator fan and circulates in the display commercial refrigerator. A capillary tube penetrating the upper bracket is connected between the condenser and the evaporator.

[0006] A second aspect of the present invention provides a display-type commercial refrigerator, which is detachably equipped with the above-mentioned integrated refrigeration system.

[0007] The present invention realizes an integrated design of the refrigeration system while reducing the volume occupied by the refrigeration system in the display-type commercial refrigerator to increase the total display area of ​​the display-type commercial refrigerator. This not only effectively ensures the refrigeration effect of the integrated refrigeration system, but also reliably guarantees its heat dissipation. In addition, it has the advantage of easy assembly and maintenance.

[0008] Other features and advantages of the present invention will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] See also Figure 1 The present invention provides an integrated refrigeration system 1, which is arranged in a display commercial refrigerator. The bottom 2 of the display commercial refrigerator is stepped, with the high-step portion located at the rear of the bottom of the display commercial refrigerator and the low-step portion located at the front of the bottom of the display commercial refrigerator. Both the high-step portion and the low-step portion are open at both ends facing the outside of the display commercial refrigerator. Figure 2 The integrated refrigeration system 1 includes a frame 11, which is arranged in the inner cavity of the high-order part at the bottom of the display commercial refrigerator. The frame 11 includes a lower bracket 111 and an upper bracket 112. The compressor 3 and the condenser 4 are installed on the lower bracket 111. A compressor fan 5 is provided in front of the compressor 3, and a condenser fan 6 is provided behind the condenser 4. External air enters from the end face of the low-order part, passes through the compressor fan 5 and the compressor 3, as well as the condenser 4 and the condenser fan 6, and is discharged from the end face of the high-order part. An evaporator 7 is provided on the upper bracket 112, and an evaporator fan 8 is provided behind the evaporator 7. The gas in the display commercial refrigerator becomes cold air after passing through the evaporator 7 and the evaporator fan 8, and circulates in the display commercial refrigerator. A capillary tube 9 penetrating the upper bracket 112 is connected between the condenser 4 and the evaporator 7.

[0012] During operation, the operating principle of the integrated refrigeration system 1 is the same as that of an ordinary refrigeration system. The compressor 3 absorbs the low-temperature and low-pressure refrigerant vapor from the evaporator 7, and after adiabatic compression by the compressor 3, it becomes high-temperature and high-pressure steam. The high-temperature and high-pressure steam in the compressor 3 is introduced into the condenser 4, and the refrigerant vapor is condensed under the same pressure. At the same time, heat is dissipated to the surrounding medium, turning it into high-pressure and low-temperature refrigerant liquid. After the high-pressure and low-temperature refrigerant liquid is throttled by the equal enthalpy in the capillary tube 9, it is converted into low-temperature and low-pressure refrigerant vapor, and then the refrigerant vapor is sent to the condenser 4. Enters the evaporator 7, so that the hot air in the box body 1 passes through the evaporator 7 and the evaporator fan 8, is cooled into cold air, and then enters the box body 1, so that refrigeration is achieved through this cycle; among them, since the condenser fan 6 is arranged behind the condenser 4, the condenser fan 6 sucks in the cold air in front of the condenser 4 and discharges it from the rear, which has a strong heat dissipation effect. In addition, since the compressor fan 5 is arranged in front of the compressor 3, the cold air of the compressor fan 5 blows to the compressor 3 and is then discharged from the rear, which not only has a good heat dissipation effect on the compressor 3, but also can improve the heat dissipation function of its integrated refrigeration system to a certain extent.

[0013] The innovation of the present invention lies in that, under the premise of reducing the volume occupied by the refrigeration system in the display-type commercial refrigerator to increase the total display area of ​​the display-type commercial refrigerator, the refrigeration system is integrated into the design. Not only can the display items observed from the door of the display-type commercial refrigerator be fully displayed and placed, thereby increasing the visual space and aesthetics, but also the display has a better heat dissipation space and the refrigeration effect is not affected. During assembly or maintenance, the integrated refrigeration system 1 can be pushed into or out of the display-type commercial refrigerator as a whole, so it has the advantage of convenient assembly and maintenance.

[0014] In this embodiment, the evaporator 7 and the evaporator fan 8 are both separated by the thermal insulation foam layer 10. The purpose is to prevent the evaporator 7 and the evaporator fan 8 from being affected by external heat, which can further improve the cooling effect of the display type commercial refrigerator.

[0015] In this embodiment, the evaporator 7 and the evaporator fan 8 are both in the shape of long strips, so as to effectively reduce the occupied height and meet the space utilization requirements of the upper floor without affecting the evaporation effect.

[0016] The present invention also provides a display-type commercial refrigerator, which is detachably equipped with the above-mentioned integrated refrigeration system.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
