1 TARIFF A REFRIGERATION DEVICE AND A REFRIGERATION METHOD FOR REFRIGERATION DEVICES This invention involves a refrigerant cycle configuration that incorporates an electronic expansion valve. It relates to cooling devices and a suitable cooling method for cooling devices. Refrigeration appliances, especially refrigerators, have a vapor compression refrigeration cycle. 5 The vapor compression refrigeration cycle is, in its simplest form, a closed system in which a refrigerant circulates. a compressor that circulates refrigerant in a cycle, the hot water is compressed after the compressor a system that allows the heat of the refrigerant in its vapor phase to be released A condenser is a capillary tube in which the refrigerant changes phase by reducing its pressure, and it is also used in refrigerators. The cabinets contain an evaporator that cools the compartments by drawing heat from inside them. 10 In refrigeration appliances, the general purpose is to have a fresh food cabinet and / or a freezer cabinet as desired. The goal is to reach and maintain certain temperatures. Today, the most important aspect of cooling devices is... The major challenge is increasing energy efficiency in the refrigerant cycle. Refrigerant To reduce the energy consumption of devices, the refrigerant cycle uses optimal evaporation. It should be designed to operate at temperatures above 15°C. However, some external components in the cooling device... These external variables can cause the evaporation temperature to decrease. One reason is that as the cabin temperature starts to drop, the evaporator inlet air temperature also decreases. It is the beginning of the process. As the evaporator inlet air temperature decreases, the evaporation temperature also decreases. This causes a decrease in evaporation temperature, which in turn leads to a decrease in cooling capacity. And it means inefficiency. 20 Chinese patent document number CN115200274, included in the known state of the art, describes a refrigerator. It belongs to the field of technology and specifically to the method of adjusting the cooling capacity of a refrigerator. It is related to. In single-cycle air-cooled refrigerators, the door of the refrigerator compartment It is common for the temperature in the freezer compartment to increase rather than decrease when opened. This situation... Temperature fluctuations in the freezer compartment cause food to freeze, thus preserving its freshness for 25 days. This affects its protection. This situation seriously negatively impacts the user experience. This The document describes a method for adjusting the cooling capacity of a refrigerator. The method depends on the ambient temperature, the condition of the refrigerator compartment door, and the temperature in the freezer compartment. This involves determining the opening of the electronic expansion valve according to the increase in pressure. Then, Freezer compartment temperature before and after opening and closing the refrigerator compartment door is 30°C. 2 The opening value of the electronic expansion valve is automatically adjusted according to the change in conditions. By adjusting the settings, the refrigerator's cooling capacity is actively adjusted. An additional electronic... Freezer under open-loop control without the need to add an expansion valve sensor. Precise temperature control and a reduction in overall energy consumption can be achieved in the compartment. The purpose of the invention described in the application is to create an energy-efficient cooling device. 5 to accomplish. Another purpose of the invention described in the application is to create a cooler in which the cabinet cooling process is accelerated. The device is to perform. Another objective of the invention in question is to increase energy efficiency on the one hand, and on the other hand... Suitable cooling for cooling devices where the cabinet cooling process is accelerated. 10 The method is to implement it. The subject matter of the invention is a refrigeration device consisting of a device housing; at least one condenser, and at least one cabinet. for cooling, at least one evaporator and at least one evaporator fan, at least one chiller a refrigerant that has at least one compressor to compress the fluid and transmit it to the condenser It includes the cycling structure. 15 The cooling unit must also have at least one cabinet temperature sensor to measure the cabinet temperature; At least one electronic expansion joint is needed to determine the refrigerant flow to the evaporator. The valve requires at least one inlet air temperature gauge to measure the air temperature at the evaporator inlet. The sensor must have at least one outlet air temperature sensor to measure the air temperature at the evaporator outlet. The sensor must have at least one inlet to measure the refrigerant temperature at the evaporator inlet. Refrigerant temperature sensor; to measure the refrigerant temperature at the evaporator outlet. It includes at least one outlet fluid temperature sensor; and a control unit. Here, the control unit is: - at an initial speed when it receives a cooling signal for cooling the cabin Starting the compressor sets the electronic expansion valve to an initial throttling value. bringing; 25 - measuring the initial evaporator temperature of the refrigerant at the evaporator outlet; - waiting for a selected waiting period; 3 - After the selected waiting time, the cabin temperature is at a selected cabin temperature. below which the compressor stops, and the cabin temperature is above the selected cabin temperature. This involves measuring the final evaporator temperature of the refrigerant at the evaporator outlet; - The temperature difference between the initial evaporator temperature and the final evaporator temperature is a selected temperature. If the difference is smaller than the first one, measure a new initial evaporator temperature; if it is larger, measure 5. air temperature at the evaporator inlet and refrigerant temperature at the evaporator inlet the temperature difference between the two selected temperatures is less than or equal to the temperature difference of a second selected temperature. checking that it is large; - If the temperature difference is smaller than the selected second temperature difference, activate the electronic expansion valve. throttling at the selected throttling rate; 10 - If the temperature difference is greater than the selected second temperature difference, the air at the evaporator outlet the temperature between the temperature and the refrigerant temperature at the evaporator outlet checks whether the difference is less than or greater than a selected third temperature difference. to do; - If the temperature difference is smaller than the selected third temperature difference, activate the electronic expansion valve at 15. throttling at the selected throttling rate; - If the temperature difference is greater than the selected third temperature difference, activate the electronic expansion valve. opening at the selected closure rate; It has been adapted for this purpose. The invention aims to ensure high energy efficiency during cabinet cooling in its applications. 20 The aim is to maintain cooling efficiency at an optimum level. This objective... Various checks are performed to achieve this, and electronic expansion is determined according to the check results. the valve is positioned at different openings or the refrigerant of the cooling compressor is different By compressing it at the specified compression ratio, it is transferred to the refrigerant cycle structure. To maintain optimum cooling efficiency, the air temperature at the evaporator inlet should be between 25°C and 25°C. The difference between the refrigerant temperature at the evaporator outlet and the evaporator outlet temperature is an optimum temperature difference. It is ensured that it does not fall below this level. When the control unit receives a cooling signal to cool the cabinet, it starts at the initial speed. to start the compressor and return the electronic expansion valve to its initial throttling value It has been adapted. Here, the cabinet can be a fresh food cabinet and / or a freezer cabinet. 30 However, the control unit monitors the evaporator via the outlet fluid temperature sensor. 4 It is adapted to measure the initial evaporator temperature of the refrigerant at the outlet. Thus The initial parameters of the fluid cycle configuration are obtained. Then... The evaporation temperature is allowed to develop by waiting for the selected waiting time. After the selected waiting time, the cabin temperature is measured via the cabin temperature sensor. is measured. If the cabin temperature is below the selected cabin temperature, the cabin is brought to the desired temperature by 5 minutes. It is detected that it is cooled and the compressor is stopped. The cabin temperature is above the selected cabin temperature. On the other hand, the temperature of the refrigerant at the evaporator outlet is the outlet refrigerant temperature. It is measured via a sensor. This measurement is the final evaporator temperature. Initial evaporator temperature if the temperature difference between the final evaporator temperature and the selected first difference is less than the temperature of the final evaporator The refrigerant at the evaporator outlet is processed by measuring a new initial evaporator temperature. 10 The process continues. The temperature difference between the initial evaporator temperature and the final evaporator temperature is one. If the selected difference is greater than the first one, is this difference due to the falling cabin temperature? This needs to be determined. For this, the initial evaporator temperature and the final evaporator temperature are needed. If the temperature difference between them is greater than a selected first difference, the air in the evaporator inlet The temperature difference between the temperature of the evaporator and the refrigerant temperature at the evaporator inlet is 15 It is checked / determined whether the selected second temperature difference is smaller or larger than the minimum required amount. Air temperature at the evaporator inlet and refrigerant temperature at the evaporator inlet If the temperature difference between them is smaller than the selected second temperature difference, then the evaporation temperature It is understood that this is due to the heat transferred to cool the cabin. In this case... Administering a cooler refrigerant to the evaporator will increase the cooling efficiency of the cabinet. 20 Reducing the electronic expansion valve's speed or increasing the compressor speed allows more air to flow into the evaporator. This will ensure the transmission of a cold coolant. Therefore, the temperature difference has been chosen. If the second temperature difference is smaller than the selected throttling rate, the electronic expansion valve will operate at a chosen throttling ratio. The temperature is reduced. This indicates that the temperature difference has not yet fallen below the optimum level, and the refrigerant flow is reduced. To improve cycle performance, the electronic expansion valve is restricted. The temperature difference is set to 25. If the second temperature difference is greater than the evaporator outlet air temperature and the evaporator temperature... the temperature difference between the refrigerant temperature at the outlet and a selected third temperature The difference is checked / determined to be smaller or larger than the selected temperature difference. If the temperature difference is less than the third, the electronic expansion valve will throttle at the selected throttling rate. If the temperature difference is smaller than the selected third temperature difference, the air temperature at the evaporator inlet is 30. the difference between the refrigerant temperature at the evaporator outlet and the temperature of the evaporator is an optimum temperature It is understood that the difference is higher than the selected third temperature difference. 5 air temperature at the evaporator inlet and refrigerant temperature at the evaporator outlet It is understood that the difference between them is less than an optimum temperature difference. The cooling cycle... The refrigerant temperature delivered to the evaporator for optimum performance. The speed should be reduced. This involves opening the electronic expansion valve or reducing the compressor speed. This will allow a less cold refrigerant to be delivered to the evaporator. The temperature difference is 5 If the selected third temperature difference is greater than the selected throttling, the electronic expansion valve will switch to the selected throttling mode. It opens at a certain rate. This indicates that the temperature difference begins to fall below the optimum level, and The electronic expansion valve is opened to improve refrigerant cycle performance. The electronic expansion valve controls the flow of refrigerant to the evaporator, i.e., the flow of the refrigerant. It is a component that can determine the speed and amount of expansion. The electronic expansion valve is throttled. 10 It increases the throttling effect in the refrigerant flowing to the evaporator. Thus, the refrigerant flowing to the evaporator... The refrigerant pressure decreases, the refrigerant expands, and its temperature drops. Electronics Opening the expansion valve reduces the throttling effect on the refrigerant flow to the evaporator. Thus, the refrigerant pressure going to the evaporator drops less, and the refrigerant flows more freely. It expands slightly and its temperature increases. 15 The air temperature at the evaporator inlet is synonymous with the temperature of the air entering the evaporator. It was used. The air temperature at the evaporator outlet is the temperature of the air exiting the evaporator. It is used synonymously with temperature. From the evaporator inlet to the evaporator outlet. Airflow is achieved with the help of an evaporator fan. In one application of the invention, the control unit reduces the temperature difference from a selected second temperature difference by 20 If the electronic expansion valve is at a maximum throttling level when it is slightly full It is adapted to increase the compressor speed at a selected speed ratio. Electronic If the expansion valve is at its maximum throttling level, it cannot be throttled any further. Therefore, the cooler... To improve fluid cycle performance, the compressor speed is selected at the chosen speed ratio. It is increased. 25 In one application of the invention, the control unit determines the temperature difference from a selected third temperature difference. If the electronic expansion valve is small, the compressor is at its maximum throttling level. It is adapted to increase its rotation speed at the selected rotation rate. Similar to the application above. In this way, if the electronic expansion valve is at its maximum throttling level, it cannot be throttled any further. Therefore... 6 Therefore, the compressor speed was selected to improve the refrigerant cycle performance. It is increased in rotation rate. In one application of the invention, the control unit determines the temperature difference from a selected third temperature difference. If the electronic expansion valve is large, the compressor is at a minimum throttling level. It is adapted to reduce its speed at the selected speed rate. The electronic expansion valve has a minimum speed of 5. At the closure level, in other words at the maximum opening level, it cannot be opened any further. Therefore, to improve refrigerant cycle performance, compressor speed needs to be increased. It is reduced at the selected rotation rate. In one application of the invention, the cooling device uses an electronic expansion valve to distribute the outgoing refrigerant. At least one capillary tube to restrict flow; essentially 10 in the refrigerant cycle configuration. Capillaries are located near the tube, before the refrigerant is delivered to the compressor. The capillary tube contains at least one heat exchange region to facilitate heat exchange. This With this application, the coolant temperature is increased as it passes through the heat exchange region. Thus, the refrigerant is heated before it reaches the compressor. It increases performance and efficiency in the cycle. 15 The subject of the invention is also to be implemented in a refrigeration device, the applications of which are described above. It relates to a suitable cooling method. The cooling method includes the following steps: - a cooling signal for cooling a cabinet at the start of a cycle compressor operation, an initial throttling of an electronic expansion valve bringing it to its value; 20 - measuring the initial evaporator temperature of the refrigerant at an evaporator outlet; - waiting for a selected waiting period; - After the selected waiting time, the cabin temperature is a selected cabin temperature.

If the first difference is smaller than the initial evaporator, the refrigerant at the evaporator outlet is a first evaporator.
