[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 Please see Figure 1-6 In this embodiment: a high and low temperature integrated machine includes a body 1. The body 1 is equipped with a refrigeration component 2 and a heating component 3. The body 1 is also equipped with a circulation component 4. The circulation component 4 includes a liquid storage tank 401 and a circulation pump 402. The liquid storage tank 401 is located inside the body 1, and the circulation pump 402 is located on one side of the body 1. The liquid storage tank 401 is provided with a circulation liquid inlet 403 and a circulation liquid outlet 404. The inner wall of the circulation liquid outlet 404 is fixedly connected to the output end of the circulation pump 402, and the inner wall of the circulation liquid inlet 403 is fixedly connected to the output end of the circulation pump 402. The refrigeration component 2 and the heating component 3 are located inside the liquid storage tank 401. A control panel 5 is provided on the upper front side of the body 1. In this embodiment, the cooling component 2 can cool the heat-conducting medium in the storage tank 401 of the circulation component 4, and the heating component 3 can heat the heat-conducting medium in the storage tank 401 of the circulation component 4. The circulation component 4 is the medium for heat transfer. When the circulation pump 402 starts, the temperature-controlled heat-conducting medium in the storage tank 401 is pumped to the external equipment that needs temperature control through the circulation liquid outlet 404. After heat exchange with it, the medium returns to the storage tank 401 through the circulation liquid inlet 403 to complete one cycle.

[0017] Furthermore, the refrigeration assembly 2 includes a compressor 201, the output end of the compressor 201 is connected to a condenser 202, the output end of the condenser 202 is connected to an economizer 203, the output end of the economizer 203 is connected to an evaporator 204, and the evaporator 204 is disposed in a liquid storage tank 401. The refrigeration component 2 is a complete vapor compression refrigeration circuit. Its evaporator 204 coil is placed in the liquid storage tank 401 of the circulation system 4. When cooling is required, the control panel 5 starts the refrigeration component 2. The low-temperature refrigerant evaporates and absorbs heat in the evaporator 204, thereby quickly cooling the heat transfer medium in the liquid storage tank 401.

[0018] Furthermore, the heating assembly 3 includes an electric heating tube 301, which is disposed in the liquid storage tank 401; The heating component 3 consists of one or more sets of electric heating tubes 301, which are also immersed in the heat-conducting medium of the storage tank 401. When heating is required, the control panel 5 connects the heating component 3 to convert electrical energy into heat energy, which directly heats the heat-conducting medium.

[0019] Furthermore, the control panel 5 includes a controller 501, the input terminal of which is connected to a temperature sensor 502, and both the cooling component 2 and the heating component 3 are electrically connected to the controller 501. The control panel 5 is the core of the entire device. The operator sets the desired target temperature value through the controller 501 on the front of the machine body 1. The temperature sensor 502 is usually installed near the circulating liquid outlet 404 to measure the temperature of the medium to be delivered most accurately. It transmits the real-time temperature data to the controller 501. The controller 501 runs a preset control program and compares the measured value with the set value. If the measured value is higher than the set value, the controller 501 will start the cooling component 2 and turn off the heating component 3; if the measured value is lower than the set value, the controller 501 will start the heating component 3 and turn off the cooling component 2; if the measured value is within the allowable error range of the set value, both the cooling and heating components can stop working. Through this closed-loop feedback control, high-precision and dynamic stability maintenance of the temperature of the heat transfer medium is achieved.

[0020] Preferably, a liquid inlet 6 is provided on one side of the upper surface of the body 1, a hydraulic gauge 7 is installed on the front side of the body 1, and a liquid level display 10 is provided on one side of the body 1. The machine body 1 is equipped with an intuitive liquid level display 10 on the outside to monitor the liquid level of the medium in the storage tank 401 and prevent dry burning or overflow. The pipeline is also equipped with a pressure gauge 7 to display the circulation pressure and determine whether the pipeline is unobstructed.

[0021] Preferably, a panel pop-up switch 8 is provided on one side of the control panel 5, and a panel power switch 9 is provided on the other side of the control panel 5.

[0022] Preferably, a heat dissipation plate 11 is provided on the lower part of the outer wall of the body 1, and casters 12 are installed at the four corners of the lower surface of the body 1; The bottom of the body 1 is equipped with casters 12, which makes it easy to move.

[0023] The working principle and usage process of this utility model are as follows: The evaporator 204 coil is placed in the liquid storage tank 401 of the circulation system 4 via the refrigeration component 2. When cooling is required, the control panel 5 activates the refrigeration component 2, and the low-temperature refrigerant evaporates and absorbs heat in the evaporator 204, thereby rapidly cooling the heat transfer medium in the liquid storage tank 401. Similarly, the electric heating tube 301 in the heating component 3 is immersed in the heat transfer medium of the liquid storage tank 401. When heating is required, the control panel 5 connects the heating component 3, converting electrical energy into heat energy to directly heat the heat transfer medium. The circulation component 4 is the medium for heat transfer. When the circulation pump 402 starts, the temperature-controlled heat transfer medium in the liquid storage tank 401 is pumped through the circulation liquid outlet 404 to external equipment requiring temperature control. After heat exchange, the medium then passes through the circulation liquid inlet 403. Returning to the storage tank 401, one cycle is completed. The operator sets the desired target temperature value through the controller 501 at the front of the machine body 1. The temperature sensor 502 is usually installed near the circulating liquid outlet 404 to measure the temperature of the medium to be delivered most accurately. It transmits the real-time temperature data to the controller 501. The controller 501 runs a preset control program, comparing the measured value with the set value. If the measured value is higher than the set value, the controller 501 will start the cooling component 2 and turn off the heating component 3; if the measured value is lower than the set value, the controller 501 will start the heating component 3 and turn off the cooling component 2; if the measured value is within the allowable error range of the set value, both the cooling and heating components can stop working. Through this closed-loop feedback control, high-precision and dynamic stability maintenance of the temperature of the heat transfer medium is achieved.
