Description

1 TARIFF MICRO-ORIFFIED TUBE-TYPE EXPANSION ELEMENT This invention relates to a micro-orifice tube-type expansion element; for evaporators, liquid lines, 5 The return line consists of expansion joint sections with micro-orifices. The invention is intended for use in capillary evaporators in the commercial refrigeration sector. Micro-perforated copper 10 to be used in place of pipe or fixed orifice expansion valve. It is a pipe expansion element. State of the Art In the commercial refrigerator industry, capillary tubes perform the same evaporation function as 15 This is being done. However, errors due to workmanship occur during the welding process. -Because the length selection in the capillary tube depends on the diameter, the cabinet tests take a long time. This is the reason. -In multi-inlet systems, the same number of inlets must be used during installation at the evaporator inlets. Due to the impossibility of manufacturing, it gives different results in each product. 20 -Since capillary tube lengths and diameters will vary according to cabinet capacity, especially r290 Excess gas charging in cases where the gas limit of propane-based refrigerant is restricted. It causes. -The production technique of capillary tubes involves producing them in roll form, and during their production... Since their diameters vary, 25 coils are produced with an outer diameter of 2.5 mm. Different diameters, such as 2.2 mm and 2.3 mm, were observed in some regions of the capillary tube. and the cabinets produced in the same module and tested have different lengths. This necessitates the use of capillary tubes. - The capillary tube must be cut carefully. 2 Because deburring requires delicate and expert workmanship, the production standard... This presents difficulties in production and results in extra quality control costs due to the labor involved. - Capillary tube fractures caused by vibration during compressor start-up and stop. It is happening. -A pressure drop due to friction in the capillary tube can occur, and the probability of sound production is 5. It is high. Benefits of the Invention 10 Our invention is for plug-in commercial refrigerators with the compressor located underneath. A 50 mm pipe, the same diameter as the liquid line, placed near the evaporator. by closing the end of a copper pipe of a certain length, and suddenly cutting off the midpoint a micro-sized hole separately drilled for each capacity to allow for pressure drop It consists of a copper pipe section. 15 Because our invention has the same diameter and constant length as the liquid pipeline, the gas There will be no change in the amount. Because this part has the same diameter as the liquid line, the coolant passes through the micro-hole. It achieves evaporation through a sudden contraction. This expansion is a refrigerant fuel. Because it atomizes the fluid like an ejector, it ensures a homogeneous distribution in the evaporator. It creates. Because this part is suitable for mass production, it does not have any features like those in capillary tubes. The workmanship will not cause any errors. The pipe is not at risk of breaking due to vibration. Installation is easy. 3 Method of Implementing the Invention A refrigeration cycle consists of a compressor, condenser, expansion valve / capillary tubes, and Evaporators are the main components of a closed-loop refrigeration system. The compressor... With its operation, the gaseous refrigerant, liquid, at high temperature and pressure. It enters a condenser to be converted into its liquid phase. The condenser converts this refrigerant into liquid phase 5. It is a heat exchanger that converts heat to its final phase. The total heat is transferred to the aluminum condenser surface. Heat is transferred to the fins via copper pipes and cooled by removing heat through fans. This happens. The cooled refrigerant passes into the liquid phase. The refrigerant in the liquid phase... When a fluid experiences a sudden change in diameter, its pressure and temperature decrease, causing it to vaporize. This low-temperature heat is transferred to the cabinet via the evaporator heat exchanger and its fans. It is transferred inside and a cooling process is carried out. Our invention allows for easier installation (and can replace fixed orifice expansion valves). (an invention), by evaporation that homogeneously atomizes with a sudden drop in pressure. The evaporator is used efficiently, depending on the tube lengths, like capillaries. It is a variable system that does not require excessive refrigerant. Suitable for serial conveyor belt production. With our invention, which is suitable and eliminates all workmanship-related errors, in a much shorter time. Cabinet tests will be conducted to ensure flawless cooling in all cabinets produced. will be provided. In a refrigeration cycle, the refrigerant exiting the compressor condenses in the condenser. , in liquid phase, enters the evaporator (1) located inside the cabinet. 20 condensed in the condenser where the refrigerant is converted to its liquid phase and closed cooling at the evaporator inlet. It contains the liquid line (2) that enables its circulation. A micro orifice expansion piece with a very low cross-section of refrigerant in the liquid phase (4) When it comes into contact with water, its pressure and temperature drop suddenly, causing it to evaporate and land on the evaporator surface. Cooling of the cabinet is ensured by transferring the low heat through the return line (3). 25 4 The system implemented to achieve the invention's purpose is shaped in the attached figures. and these shapes; Figure 1.
