[0002] With the widespread application of refrigeration technology, refrigeration units have become indispensable equipment in industrial production, commercial buildings, and households. Traditional refrigeration system design primarily focuses on cooling efficiency and energy consumption, typically employing simple heat dissipation methods to handle condensation heat. For example, in vapor compression refrigeration systems, the high-temperature, high-pressure refrigerant gas releases heat and liquefies in the condenser; this heat is carried away by cooling water or air and directly discharged. Taking common commercial refrigeration systems as an example, the temperature of the discharged condensation heat is usually between 40-60℃. This waste heat resource is not effectively recovered and utilized, resulting in energy waste. Utility Model Content

[0029] like Figure 1 and Figure 2 As shown, an embodiment of this application provides a refrigeration unit 100 with a heat recovery module, mainly used to recover waste heat from the refrigeration module 120. The refrigeration unit 100 with a heat recovery module includes a refrigeration module 120 and a waste heat recovery module 110.
[0030] The refrigeration module 120 has a cold-side outlet 121 and a hot-side outlet 122. The cold-side outlet 121 is the condensate outlet of the refrigeration module 120, and the hot-side outlet 122 is the outlet for discharging condensed heat.
[0031] Traditional refrigeration system design mainly focuses on cooling effect and energy consumption. The condensation heat of some refrigeration modules is between 40-60℃. The condensation heat is usually handled by simple heat dissipation methods. These waste heat resources are not effectively recovered and utilized, resulting in energy waste.
[0032] In response to the above issues, please refer to the following: Figure 3The waste heat recovery module 110 of this application includes a water tank 111, a heating pipe 112, a connecting pipe 113, and a drive mechanism 114. The heating pipe 112 is disposed inside the water tank 111, and the drive mechanism 114 drives the heating pipe 112 to rotate. The connecting pipe 113 connects the cold side outlet 121 and the heating pipe 112. In this way, the condensation heat of the refrigeration module 120 flows into the heating pipe 112 of the water tank 111 through the connecting pipe 113 to heat the water in the water tank 111. At the same time, the drive mechanism 114 drives the heating pipe 112 to rotate, thereby increasing the contact area between the water and the waste heat of the refrigeration module 120, accelerating the heat transfer speed, making the waste heat recovery process more complete, and reducing energy waste.
[0033] In one embodiment, the heating tube 112 is spiral-shaped, which increases the contact area between the water and the heating tube, and also increases the heat conduction area between the waste heat and the water.
[0034] In some embodiments, the waste heat recovery module 110 further includes a first rotating seat 115 and a second rotating seat 116. The first rotating seat 115 is connected to the connecting pipe 113 and the heating pipe 112, and the second rotating seat 116 is disposed in the water tank 111 and connected to the end of the heating pipe 112 away from the connecting pipe 113.
[0035] like Figure 3 As shown, the heating tube 112 is vertically arranged, with one end of the heating tube 112 at the top and the other end at the bottom. The first rotating seat 115 is arranged above the heating tube 112. The first rotating seat 115 is tubular and connects the tube 113, the first rotating seat 115 and the heating tube 112.
[0036] The second rotating seat 116 is located below the heating tube 112. The first rotating seat 115 and the second rotating seat 116 are respectively connected to the heating tube 112 and cause the heating tube 112 to rotate.
[0037] In some embodiments, the drive mechanism 114 includes a motor 1141, a drive wheel 1142, and a driven wheel 1143.
[0038] like Figure 3 As shown, motor 1141 is located outside water tank 111, and the output shaft of motor 1141 is inserted into water tank 111. Drive wheel 1142 and driven wheel 1143 are located inside water tank 111. Drive wheel 1142 is connected to the output end of motor 1141, and driven wheel 1143 is connected to heating tube 112. Drive wheel 1142 and driven wheel 1143 are meshed together. When motor 1141 starts, it drives drive wheel 1142 to rotate, which in turn drives driven wheel 1143 to rotate, which in turn drives heating tube 112 to rotate, accelerating the transfer of heat from heating tube 112 to water.
[0039] In some embodiments, the water tank 111 includes a tank body 1111 and a top cover 1112. A drive mechanism 114 and a first rotating seat 115 are disposed on the top cover 1112, and a heating tube 112 is disposed inside the tank body 1111. Integrating the drive mechanism 114 and the first rotating seat 115 into the top cover 1112 avoids occupying the internal space of the tank body 1111, facilitates liquid flow and cleaning, and the top cover 1112 structure is easy to disassemble, which is beneficial for the maintenance or replacement of the drive components.
[0040] In some embodiments, such as Figure 1 and Figure 2 As shown, the water tank 111 also includes a pressure relief valve 1113, a water inlet 1114 and a water outlet 1115. The pressure relief valve 1113 and the water inlet 1114 are spaced apart on the top cover 1112, and the water outlet 1115 is located on the tank body 1111 and is located away from the top cover 1112.
[0041] Cold water is added to the water tank 111 through the inlet 1114, and heated water is discharged through the outlet 1115. A pressure relief valve 1113 is installed to regulate the air pressure inside the water tank 111, reducing the possibility of the top cover 1112 being pushed up by hot air. The pressure relief valve 1113 is located on the top cover 1112 for easy observation and maintenance. The rational layout of the pressure relief valve 1113 and the inlet 1114 improves the safe operation of the water tank 111 under high pressure conditions.
[0042] In some embodiments, such as Figure 1 and Figure 2 As shown, the waste heat recovery module 110 also includes an insulation component 117, which is sleeved on the outside of the connecting pipe 113 to insulate the condensation heat generated by the refrigeration module 120 and improve the waste heat recovery efficiency.
[0043] In some embodiments, the refrigeration module 120 includes an evaporator 123, a compressor 124, and a condenser 125 connected in sequence, with a cold-side outlet 121 disposed on the evaporator 123 and a hot-side outlet 122 disposed on the condenser 125.
[0044] Evaporator 123 absorbs heat, causing the refrigerant to change from a liquid to a gaseous state; compressor 124 compresses the refrigerant gas, increasing its pressure and temperature; condenser 125 releases heat, causing the refrigerant to change from a gaseous to a liquid state. The heat of condensation is discharged from condenser 125.
[0045] like Figure 3 As shown, the cooling process of the cooling module 120 is as follows:
[0046] The low-temperature, low-pressure refrigerant inside the evaporator 123 is drawn into the compressor 124, where it is compressed into a high-temperature, high-pressure gas. This high-temperature, high-pressure gas is then transported into the condenser 125, where external cold air is supplied to cool and exchange the high-temperature, high-pressure gas. The gas is then throttled and depressurized through an expansion valve, and the low-temperature, low-pressure wet vapor is transported into the evaporator 123. After heating and evaporation, the vapor is discharged through the cold-side outlet 121, thus providing refrigeration.
[0047] In some embodiments, the refrigeration module 120 further includes a return pipe 126, which connects the condenser 125 and the evaporator 123. The return pipe 126 is used to return liquid refrigerant to the evaporator 123. Figure 3 As shown, low-temperature, low-pressure wet steam is transported to the interior of evaporator 123 through reflux pipe 126, heated and evaporated, and then discharged through cold side outlet 121 for refrigeration.
[0048] In some embodiments, the refrigeration module 120 further includes a fan 127, an air inlet pipe 1281, and a blower pipe 1282. The blower pipe 1282 is connected to the air outlet side of the fan 127 and the condenser 125, and the air inlet pipe 1281 is connected to the air inlet side of the fan 127.
[0049] like Figure 3 As shown, the fan 127 uses the air inlet pipe 1281 and the air blowing pipe 1282 to transport cold air from the outside to the condenser 125, thereby cooling and exchanging the high-temperature and high-pressure gas inside the condenser 125.
[0050] In some embodiments, the refrigeration module 120 further includes a housing 129, within which an evaporator 123, a compressor 124, a condenser 125, a return pipe 126, a fan 127, and a blower pipe 1282 are all disposed. Figure 3 As shown, all key components are integrated into a single housing 1111, simplifying the structure, reducing external connectors, and improving overall compactness. Optimized internal layout and airflow design improve heat exchange efficiency and cooling performance; the integrated design reduces the impact of the external environment on the system, enhancing its stability and reliability; and the integrated design reduces the footprint, making it suitable for applications with limited space.
[0051] In some embodiments, the bottom of both the housing 129 and the water tank 111 are provided with support feet 130 for support, thereby enhancing the stability of the refrigeration module 120 and the waste heat recovery module 110.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.
