Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration units, and in particular to an energy-saving refrigeration unit. Background Art

[0002] A refrigeration unit is a common refrigeration equipment, usually used for refrigeration of cold storage, food refrigerators, etc., and an air-cooled condenser is a common component of a refrigeration unit. A refrigeration unit usually includes a compressor (compressor-like subsystem), a condenser, an expansion valve, an evaporator and a control system. Among them, a heat exchanger is an important component of a refrigeration unit. A heat exchanger is an energy-saving device that transfers heat between two or more fluids at different temperatures. It transfers heat from a higher-temperature fluid to a lower-temperature fluid, so that the fluid temperature reaches the specified indicators of the process to meet the needs of the process conditions. It is also one of the main equipment for improving energy utilization.

[0003] After searching, according to the patent network CN117450679A, an energy-saving refrigeration unit was announced, including a compressor, a condenser, a heat exchanger body and a throttling device connected to each other. The heat exchanger body includes a shell and multiple groups of heat exchange tubes installed in the shell. A cleaning mechanism is installed on the heat exchange tube, and the cleaning mechanism is used to clean the surface of the heat exchange tube; the cleaning mechanism provided by the invention can remove frost or ice on the surface of the heat exchange tube through the cleaning mechanism when in use, thereby preventing the frost or ice from affecting the heat exchange efficiency of the heat exchanger and indirectly reducing the heat exchange energy consumption.

[0004] After searching, according to the patent network CN220038804U, an energy-saving refrigeration unit was announced, including a main shell, the main shell including an inner protective cover, a heat preservation cover and a heat insulation cover, a sliding frame is slidably plugged into one side of the main shell, a cooling pipe is provided in the sliding frame, the cooling pipe is S-shaped, and both ends of the cooling pipe pass through the sliding frame, one side of the main shell is fixedly connected to an air inlet pipe, and the other side of the main shell is fixedly connected to an air outlet pipe, and the outer wall of the air outlet pipe is sleeved with a heat insulation tube, a sealing gasket is bonded to one side of the sliding frame, and the sealing gasket contacts the main shell, and two support plates are fixedly connected between the top inner wall and the bottom inner wall of the sliding frame, and the cooling pipe is plugged into the support plate. The utility model uses the heat preservation cover and the heat insulation cover to keep warm and insulate, thereby reducing the loss of cold air, and then uses the heat preservation tube to keep warm when the cold air is discharged, thereby reducing the loss of cold air, which is beneficial to energy saving of resources.

[0005] However, although the existing refrigeration unit can operate the refrigerator well when in use, the size adjustment effect of the inner wall diameter of the air intake pipe of the refrigerator is not high during daily use, and the synchronous sealing and dust-proof effect when the air intake pipe is not in use is not high. At the same time, when the connecting cover needs to be disassembled, the synchronous engagement, pulling and disassembly effect of the fan in the air intake pipe is not high, so that dust will be adsorbed on the surface of the fan when the fan is used for a long time, affecting the dust-proof effect inside the refrigerator, increasing the functional loss of the refrigerator, affecting the energy-saving effect of the daily use of the refrigerator, and not meeting people's use needs.
