Description

1 TARIFF INNOVATION IN ICE CREAM DISPLAY CABINETS USED FOR DISPLAY PURPOSES. TECHNICAL AREA 5 The invention is suitable for retail food sales outlets such as supermarkets, grocery stores and bakeries that use commercial type refrigerators. This relates to ice cream display cabinets used for display purposes in businesses. Specifically, these To save energy and increase ease of use in cabinets, heating elements are used. It relates to an innovative system that uses Low-e coated insulating glass instead of regular glass. 10 STATE OF THE ART Ice cream display cabinets typically have heated glass panels. It is used. In ice cream display cabinets, heated glass, glass 15 It produces condensation by heating with an electric current thanks to a thin metal layer placed on its surface. It is a special type of glass that prevents leakage. This glass is especially used in the doors of ice cream freezers. or glass partitions, providing a clear view that does not obstruct the display of products inside. It is used to provide this. Heated glass panels withstand low temperatures inside the cabinet, ranging from -20°C to -15°C. It is exposed to an ambient temperature between +22°C and +27°C. This temperature difference between the two points... This causes condensation and fogging to form on the outer surface of the glass. Condensation To prevent this, thin wire resistors are placed on the inner surface of the glass. These resistors, It is operated using electrical energy and solves the condensation problem by heating the glass surface. 25 It aims to solve the problem. The heated glass panels in ice cream display cabinets often fog up. While it offers an effective solution for increasing product visibility by blocking access, it has some shortcomings. There are also disadvantages. One of them may be high energy consumption. Glass 30 Using an electric current to heat its surface, thus increasing the cabinet's total energy consumption. This can increase the temperature. Additionally, heating these windows can sometimes create temperature imbalances. The warming of the glass surface can create a contrast with the cold air inside, and this can This can have a negative impact on energy efficiency. 35 Heating-resistant glass systems require continuous electrical energy to operate. Heating element power. And as the surface area of ​​the glass increases, energy consumption also increases significantly. For example, in classic glass... 2 The operating power for resistance-assisted windshields used with this method is typically between 110W and 130W. This situation increases operating costs and is not environmentally sustainable. It does not offer a solution. Furthermore, placing the resistors on the inner surface of the glass during production... This complicates the processes and increases costs. The resistors used degrade over time. They can malfunction, which increases maintenance and repair costs. 5 Another drawback is related to long-term durability. Resistance glass systems handle heating and cooling. problems such as surface wear or cracking over time due to cycles This can occur. This can prevent the glass from functioning efficiently and necessitate its replacement. This may be necessary. Also, the heating of the glass causes more moisture from the outside to accumulate. 10 This is possible. The effectiveness of these glasses is particularly high in environments with high humidity levels. This can decrease. High costs can also be an obstacle. Resistive These windows are more expensive compared to standard windows. This is especially true for small businesses or those on a budget. For locations with limitations, this represents an additional cost. In the known state of the art, ITMC application number 20080149 “On the Evaporator The invention application titled "Refrigerator with rainwater removal device" was submitted as an "Industrial invention". The current patent application eliminates ice formation in a refrigerator's evaporator. It relates to a system that lifts. This invention is particularly relevant to commercial refrigerated benches, but It can also be extended to non-commercial (household) and industrial refrigerators. As is known, a 20 A compression refrigeration system consists of a compressor, a condenser, and an evaporator. The refrigerant (normally Freon or ammonia) is compressed by the compressor, so that Both temperature and pressure increase, and it turns into liquid. The condenser (outer grid) removes the liquid coolant. It cools and removes heat. The liquid coolant from the condenser passes through a rolling element. (thermostatic valve or manual regulator) passes through and the evaporator (heat exchange 25 The tube bundle equipped with fins is injected into a heat exchanger, where it expands. It is returned to its gaseous state. During this phase change, the evaporator heat exchanger in the refrigerator compartment It absorbs the heat from the products stored inside and transfers it to the cooler. Gas coming from the evaporator. the refrigerant in this state until the desired temperature is reached inside the refrigerator compartment. The fluid is sent to the compressor to start a new cycle, and a thermostat stops the compressor. 30 In medium and low pressure cooling systems, the surfaces of the evaporator fins. Temperatures can generally range between -10°C and -30°C, and may drop even lower in certain situations. Therefore, frost formation on the surfaces of evaporator fins occurs because moist air and water... surfaces with temperatures below the freezing point, that is, as is known, 0°C It is a natural phenomenon caused by the encounter of ice and water. The ice covering the evaporators, 35 Given that it is an excellent thermal insulator, its heat exchange performance... It is clear that this reduces the cooling capacity. In commercial refrigerators, the cooled area remains in contact with the outside environment. This 3 Therefore, the air circulating in the evaporator (natural or forced (fan-assisted)) comes into contact with the outside air. It constantly gains moisture, and this moisture freezes onto the surfaces of the fins of the evaporator tubes. It continues to settle in this way. Over time, frost formation becomes excessive and the system Its performance is no longer sufficient to maintain the desired temperature inside the cooler. This In these situations, therefore, to restore optimum operating conditions, eliminate the frost. 5 "A defrosting system is needed that removes and cleans the evaporator surfaces." It is defined. In the known state of the art, application number EP 2104444 refers to “Transparent containers with ice cream containers”. The patent application titled "Refrigerated display case made of material" contains the following invention: "The current patent application, 10 It relates to a refrigerated display case with ice cream containers made of transparent material. Refrigerated display cases, traditionally used to sell homemade ice cream, are basic. It has a standard configuration and includes a wooden cooling unit and associated piping. It consists of a large bed base made of sheet metal. The top of this base is covered with various 15 rectangular metal containers used to display different types of ice cream. It is essentially covered by a horizontal wall with openings through which it can be placed. Each container has its own corresponding designed to interfere with the upper surface of the cladding wall around the opening, It has a protruding edge; so that the entire container fits inside the opening. Uncontrolled entry is prevented. Considering the above, the display window... Customers standing in front can only see the top opening of the containers; 20 side walls concealed by being placed inside the base or sheet metal base structure of the containers They cannot see. The base allows them to see the ice cream containers, cooling them to the desired temperature. It supports the upper glass partition that maintains the temperature and protects against dust, insects, and other contaminants. The back of the glass partition is open so that sales assistants can easily access the ice cream containers. It is described as "equipped with a wall". 25 In conclusion, the existence of the above problems and the inadequacy of the current solutions are related to the technical aspects. This has made it necessary to make improvements in this field.
