Description

Especially in subtropical and tropical regions, the high temperature and high humidity environmental conditions pose severe challenges to the thermal insulation performance and condensation performance of refrigerated display cabinets.
[0003] Although traditional LOW-E coated glass can reduce heat conduction to a certain extent, its heat transfer coefficient is relatively high, and it is difficult to meet the door insulation requirements in high heat and high humidity environments. In hot areas, when the room temperature is high, the temperature difference between the temperature inside the freezer and the room temperature will increase. If the indoor humidity is high and the glass door temperature is low, condensation is easy to form on the surface of the glass door. Under the conditions of 32°C ambient temperature and 65% humidity, traditional LOW-E coated glass can maintain a certain insulation effect, but under the environment of 35°C ambient temperature and 75% humidity, the door condensation phenomenon is serious, affecting the display effect of the horizontal freezer.

DETAILED DESCRIPTION

[0023] A single-layer glass door body with an ultra-low thermal conductivity LOW-E film for a horizontal refrigerated display cabinet comprises an aluminum alloy door frame 1, the inner wall of the aluminum alloy door frame 1 is provided with a first sliding door 2 and a second sliding door 3 for opening and closing the display cabinet, the first sliding door 2 and the second sliding door 3 can both be translated along a predetermined track inside the aluminum alloy door frame 1, the inner wall of the aluminum alloy door frame 1 is provided with a heating film 11 for heating the aluminum alloy door frame 1, a temperature sensor 12 is provided inside the aluminum alloy door frame 1, the first sliding door 2 comprises an installation glass 21, the top of the installation glass 21 is provided with an outer glass 22, the bottom of the outer glass 22 is provided with an inner glass 23, a chamber is formed among the installation glass 21, the outer glass 22 and the inner glass 23, argon gas is injected into the chamber, a push-pull handle 25 is provided on the top of the outer glass 22, the installation glass 21, the outer glass 22 and the inner glass 23 are all made of LOW-E glass with ultra-low reflectivity, and an air drying device 4 is provided on both sides of the aluminum alloy door frame 1.
[0024] In this embodiment, please refer to Figure 2 , Figure 5The air-drying device 4 includes an outer shell 41, an inner cavity of the outer shell 41 is provided with a mounting seat 42, one side of the mounting seat 42 is provided with two air diffusers 43, the air outlet of the air diffuser 43 corresponds to the top surface of the first sliding door 2 or the second sliding door 3, and the other side of the mounting seat 42 is provided with a fan 44 for generating high-speed airflow, and the top of the outer shell 41 is provided with an air suction port 45 at the air suction end of the fan 44. In this embodiment, a high-speed airflow is generated by the fan 44, and the airflow is blown to the surfaces of the first sliding door 2 and the second sliding door 3 through the air diffuser 43, thereby accelerating the convection speed between the surfaces of the first sliding door 2 and the second sliding door 3 and the air. In a high humidity environment, the airflow can quickly take away the moisture on the glass surface, reduce the humidity, and prevent condensation from forming.
[0025] In this embodiment, please refer to Figure 3-4 A drain port 211 is provided on one side of the installation glass 21, a guide groove 26 is provided on the top of the outer glass 22, and the inner cavity of the guide groove 26 is arranged to be inclined toward the drain port 211. In this embodiment, an air flow is generated by the air drying device 4 to blow the condensation on the surface of the outer glass 22 into the inner cavity of the guide groove 26, and the water flow moves along the inner cavity of the guide groove 26 and is discharged through the drain port 211.
[0026] In this embodiment, please refer to Figure 2 The temperature sensor 12 is used to detect the ambient temperature, and the temperature sensor 12 is electrically connected to the heating film 11. A control circuit is also provided inside the aluminum alloy door frame 1. When the ambient temperature detected by the temperature sensor 12 rises to a preset threshold value, the control circuit controls the power supply to increase the output power to the heating film 11. In this embodiment, after the temperature sensor 12 detects that the external temperature has increased significantly, the power supply inside the freezer increases the output power to the heating film 11, so that the heating effect of the heating film 11 is improved, thereby increasing the temperature of the first sliding door 2 and the second sliding door 3, avoiding excessive temperature difference and causing condensation.
[0027] In this embodiment, please refer to Figure 2-3 The first sliding door 2 and the second sliding door 3 have the same internal structure, and the second sliding door 3 is provided with a magnetic sealing seat that adapts to and attracts the magnetic sealing strip 24. In this embodiment, when the first sliding door 2 and the second sliding door 3 are in the closing process, since the corresponding positions of the tops of the doors are provided with mutually attractive magnetic sealing devices, when the doors are closed to the appropriate positions, suction is generated, which automatically adsorbs and guides the doors to close, thereby solving the problem of loose closing causing cold air leakage inside the freezer.
[0028] In this embodiment, please refer to Figure 3The middle glass installation glass 21, the outer glass outer glass 22, and the inner glass inner glass 23 are all made of glass materials with ultra-low emissivity E=0.035 and thermal conductivity K=3.24. In this embodiment, by adopting this glass material, the thermal conductivity K of the finished glass door can be reduced to about 1.0, thereby reducing the power consumption of the whole machine by about 5%. In addition, the glass door remains condensation-free under the ambient temperature of 35°C and the humidity of 75%.
[0029] Working principle of this utility model:
[0030] Step 1: The outside temperature is detected in real time by the temperature sensor 12. When the outside temperature becomes high, the power supply in the freezer is controlled by the temperature sensor 12. The output power of the heating film 11 is adjusted by the power supply to make the heating effect of the heating film 11 stronger. The aluminum alloy door frame 1 is heated by the heating film 11. When the temperature of the aluminum alloy door frame 1 rises, due to its good thermal conductivity, the heat is transferred to the first sliding door 2 and the second sliding door 3, so that the temperature of the first sliding door 2 and the second sliding door 3 is significantly increased, until the temperature of the first sliding door 2 and the second sliding door 3 is heated to a temperature higher than the dew point temperature of the indoor air, effectively reducing the generation of condensation. By injecting inert gas argon into the first sliding door 2 and the second sliding door 3, which has lower thermal conductivity and electrical conductivity, the heat transfer is further reduced, the thermal insulation effect of the glass door body is improved, and the energy consumption is reduced.
[0031] Step 2: By providing an air-drying device 4, high-speed circulating air is generated through the air-drying device 4 to accelerate the surface and air convection speed of the first sliding door 2 and the second sliding door 3. In a high humidity environment, the airflow can quickly take away the moisture on the glass surface, reduce the humidity, and prevent condensation from forming. The condensation formed on the surface of the glass door is blown into the inner cavity of the guide groove 26 by the wind. Since the inner cavity of the guide groove 26 is arranged to be inclined toward the drain outlet 211, when the condensation is blown into the guide groove 26, it slides along the inner cavity of the guide groove 26 and is discharged to the outside through the drain outlet 211.

The above embodiments and descriptions are only for explaining the principle of the utility model. The utility model may have various changes and improvements without departing from the spirit and scope of the utility model.
