[0053] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the embodiments of the present invention will be more comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, many specific details are provided to provide a full understanding of the implementation of the embodiments of the present invention.

[0054] The foaming fixture needs to be heated during the production process. Currently, most of the heating equipment used is an electric heating tube mold temperature controller. When the high-pressure foaming machine is running, the raw material tank and hydraulic station will generate heat, which needs to be cooled by refrigeration equipment. Currently, most of them use air-cooled chillers to discharge the heat generated by hot spots such as material tanks and hydraulic stations into the surrounding environment. Especially in hot weather, the ambient temperature is high, and the production process heating and refrigeration equipment generates a lot of heat, causing the temperature in the production workshop to rise quickly and the working environment of the workplace is poor. The air conditioner is turned on in the foaming enclosure and other areas to cool the production area, which eventually generates a large amount of heat energy and discharges it to the outdoors. Carbon emissions are not conducive to ecological environmental protection.

[0055] In order to solve the above problems, the present application embodiment provides an energy-saving heating and cooling dual-channel all-in-one machine, referring to Figure 1 As shown, it includes: a refrigeration component 100, a heating component 200 and a compression component 300; wherein the compression component 300 includes a compressor 310, a low-pressure pipe group 320 and a high-pressure pipe group 330.

[0056] Specifically, the refrigeration component 100 is used in the cooling process, and is generally composed of a condenser and related refrigerant circulation pipes. The evaporator is used to absorb the heat of the heat-generating components (such as the raw material tank and the hydraulic station), and the condenser releases the absorbed heat to the outside or recovers the heat through other means. The heating component 200 is used in the heating process, and transfers heat energy to the components that need to provide heat, such as the foaming fixture.

[0057] The compressor 310 in the compression assembly 300 serves as a power source for the refrigeration cycle and the heating cycle, and increases the pressure and temperature of the refrigerant or the working medium by compressing the refrigerant. The low-pressure pipe group 320 connects the refrigeration assembly 100 with the air inlet end of the compressor 310, and is used to deliver the low-temperature and low-pressure refrigerant or the working medium to the compressor 310. The high-pressure pipe group 330 connects the air outlet end of the compressor 310 with the heating assembly 200, and is used to deliver the high-temperature and high-pressure refrigerant or the working medium to the next step of the heating or refrigeration cycle.

[0058] In particular, one end of the low-pressure pipe group 320 away from the compressor 310 is connected to the end of the high-pressure pipe group 330 away from the compressor 310, forming a closed-loop system, allowing the refrigerant or working medium to be efficiently converted between two cycles (cooling and heating) without the need for external heat discharge, thereby achieving energy recycling.

[0059] The refrigeration process in this embodiment is as follows: when the heat generating components of the high pressure foaming machine need to be cooled, the refrigerant absorbs heat and evaporates in the refrigeration assembly 100, and is then sucked in and compressed by the compressor 310 to increase its temperature and pressure. The high pressure refrigerant enters the heating assembly 200 through the high pressure pipe assembly 330, where it releases heat to the external environment or utilizes the heat through a heat recovery mechanism.

[0060] The heating process is as follows: when the foaming fixture needs to be heated, the high-pressure and high-temperature refrigerant or special working medium transfers heat to the heating object directly or through a heat exchanger in the heating component 200. At the same time, the low-pressure pipe group 320 continues to recover the low-temperature medium from the evaporator end of the refrigeration cycle to maintain the cycle.

[0061] This embodiment realizes energy conversion and recycling in the cooling and heating process by designing a closed-loop system, reduces heat emissions to the external environment, and reduces the need for additional cooling equipment such as air conditioners. Because the power consumption and heat energy directly discharged into the atmosphere by relying on traditional systems are reduced, carbon emissions are significantly reduced. At the same time, through integrated design, the energy efficiency ratio of the overall system is improved, and energy can be managed and utilized more effectively than independently operated heating and cooling equipment.

[0062] In some embodiments of the present application, reference Figure 1 and Figure 2 As shown, the refrigeration assembly 100 includes: a cold water tank 110, a cold water pump 120 and a first heat exchanger 130; the low-pressure pipe group 320 is connected to the first heat exchanger 130, the water outlet of the cold water tank 110 is connected to the water inlet of the cold water pump 120, the water outlet of the cold water pump 120 is connected to the water inlet of the first heat exchanger 130, and the water outlet of the first heat exchanger 130 is connected to the water inlet of the cold water tank 110; the first heat exchanger 130 is configured to cool the equipment.

[0063] It is understandable that circulating water or other cooling medium for cooling is stored in the cold water tank 110. It is designed with a water outlet and a water inlet, which are respectively used to output the cooling medium to the cooling circulation system and receive the cooling medium reflux after heat exchange. The cold water pump 120 is the power source for the circulation of the cooling medium. The water inlet of the cold water pump 120 is connected to the water outlet of the cold water tank 110, and its water outlet is connected to the water inlet of the first cold and heat exchanger 130. The cold water pump 120 is responsible for pumping the cooling medium in the cold water tank 110 to the first cold and heat exchanger 130 for heat exchange.

[0064] The first heat exchanger 130 generally has a cooling medium channel and a refrigerant channel inside, and the cooling medium (such as water) flows in the cooling medium channel, and the refrigerant circulates in the refrigerant channel. When the high-pressure and high-temperature refrigerant passes through the refrigerant channel, it releases heat to the cooling medium, thereby reducing the temperature of the refrigerant and increasing the temperature of the cooling medium. The cooled refrigerant then enters the low-pressure pipe group 320 of the compression assembly 300 to prepare for the next cycle. The heated cooling medium returns to the cold water tank 110 and can be cooled by natural cooling or an additional heat dissipation device for reuse. Among them, the low-pressure pipe group 320 is responsible for transporting the refrigerant cooled by the first heat exchanger 130 to the air intake end of the compressor 310 to start a new refrigeration cycle.

[0065] This embodiment forms a closed-loop cooling system by integrating the cold water tank 110, the cold water pump 120 and the first cold and heat exchanger 130, which can effectively absorb and transfer the heat of the high-pressure foaming machine and other equipment, and at the same time avoid the problem of traditional air-cooled chillers directly discharging heat to the surrounding environment by circulating the cooling medium (such as water). In addition, by accurately controlling the flow rate and temperature of the cooling medium, the temperature of the equipment can be accurately adjusted, the cooling efficiency can be improved, and energy waste can be reduced.

[0066] This embodiment utilizes the evaporation heat absorption characteristics of the refrigerant in the first cold and heat exchanger 130 to absorb the heat generated by the equipment, and takes the heat away through the circulating cooling medium. At the same time, the refrigerant is compressed and condensed by the compressor 310 to achieve the recycling of the refrigerant. The evaporation heat absorption characteristics of the refrigerant in the first cold and heat exchanger 130 are utilized to absorb the heat generated by the equipment, and the heat is taken away through the circulating cooling medium. Through the closed-loop cooling system, the heat emission to the external environment is reduced, the carbon emission is reduced, and the noise and hot air generated by the traditional air-cooled chiller are avoided. The impact on the surrounding environment.

[0067] In some embodiments of the present application, continue to refer to Figure 1 and Figure 2 As shown, the heating component 200 includes: a hot water tank 210, a hot water pump 220 and a second heat exchanger 230; the high-pressure pipe group 330 is connected to the second heat exchanger 230, the water outlet of the hot water tank 210 is connected to the water inlet of the hot water pump 220, the water outlet of the hot water pump 220 is connected to the water inlet of the second heat exchanger 230, and the water outlet of the second heat exchanger 230 is connected to the water inlet of the hot water tank 210; the second heat exchanger 230 is configured to heat the mold.

[0068] It is understood that circulating water or other heating medium for heating is stored in the hot water tank 210. It is designed with a water outlet and a water inlet, which are used to output the heating medium to the heating circulation system and receive the heating medium reflux after heat exchange. The heating medium in the hot water tank 210 is heated to the required temperature during the heating process to provide heat energy.

[0069] The hot water pump 220 is the power source for the circulation of the heating medium. The water inlet of the hot water pump 220 is connected to the water outlet of the hot water tank 210, and the water outlet is connected to the water inlet of the second cold heat exchanger 230. The hot water pump 220 is responsible for pumping the heating medium in the hot water tank 210 to the second cold heat exchanger 230 for heat exchange.

[0070] The second heat exchanger 230 is used to heat the mold. It generally has a heating medium channel and a refrigerant channel inside. The heating medium (such as water) flows in the heating medium channel, and the refrigerant circulates in the refrigerant channel. When the low-pressure and low-temperature refrigerant passes through the refrigerant channel, it absorbs heat from the heating medium, thereby increasing the temperature of the refrigerant and reducing the temperature of the heating medium. The heated refrigerant then enters the high-pressure pipe group 330 of the compression assembly 300 to prepare for the next cycle of heating process. The cooled heating medium returns to the hot water tank 210 and may be reheated by an additional heating device for reuse.

[0071] This embodiment forms a closed-loop heating system by integrating the hot water tank 210, the hot water pump 220 and the second cold and heat exchanger 230, which can effectively transfer the heat energy generated by the compressor 310 to the heating medium, and provide stable and efficient heating energy for the mold by circulating the heating medium. Furthermore, this embodiment utilizes the condensation heat release characteristics of the refrigerant in the second cold and heat exchanger 230 to transfer the heat energy generated by the compressor 310 to the heating medium, and provide the required heating energy for the mold by circulating the heating medium.

[0072] In some embodiments of the present application, continue to refer to Figure 2 As shown, the energy-saving heating and cooling dual-channel integrated machine also includes: an air heat exchanger 400, and the high-pressure pipe group 330 also includes a heating three-way valve 331 and a liquid reservoir 332; the heating three-way valve 331 has a heating first end, a heating second end and a heating third end. The heating first end is connected to the air outlet end of the compressor 310, the heating second end is connected to the heat outlet end of the second cold and heat exchanger 230, the heating third end is connected to the heat inlet end of the air heat exchanger 400, the heat outlet end of the air heat exchanger 400 is connected to the liquid reservoir 332, and the liquid reservoir 332 is connected to the heat inlet end of the second cold and heat exchanger 230.

[0073] The air heat exchanger 400 can use ambient air as a cooling medium and absorb heat from the refrigerant through a heat exchange process, thereby cooling the refrigerant. Its heat inlet end is connected to the heating third end of the heating three-way valve 331 to receive high-temperature and high-pressure refrigerant from the outlet end of the compressor 310; its heat outlet end is connected to the liquid accumulator 332 to transport the cooled refrigerant to the liquid accumulator 332 for storage.

[0074] The heating first end, heating second end and heating third end of the heating three-way valve 331 can be used to switch the flow direction of the refrigerant according to system requirements. The heating first end is connected to the air outlet of the compressor 310 to receive high-temperature and high-pressure refrigerant; the heating second end is connected to the heat outlet end of the second cold and heat exchanger 230. When the system is in heating mode, the refrigerant flows to the second cold and heat exchanger 230 through this path for heat exchange; the heating third end is connected to the heat inlet end of the air heat exchanger 400. When the system needs to cool the refrigerant, the refrigerant is guided to the air heat exchanger 400 through this path.

[0075] The liquid storage tank 332 is used to receive the cooled refrigerant from the air heat exchanger 400 and provide the refrigerant to the heat inlet end of the second cold-heat exchanger 230 when necessary to ensure stable operation of the system.

[0076] In this embodiment, by introducing the air heat exchanger 400 and the heating three-way valve 331, flexible control of the refrigerant flow direction is achieved, thereby solving the problems of low thermal energy utilization efficiency and complex refrigerant management in the traditional heating and cooling system. In the heating mode, the heating three-way valve 331 guides the refrigerant to the second cold and heat exchanger 230 for heat exchange to provide heating energy for the mold; when the refrigerant needs to be cooled, the heating three-way valve 331 switches to the air heat exchanger 400 path, using ambient air as the cooling medium, effectively reducing the temperature of the refrigerant and improving the overall energy efficiency of the system.

[0077] In some embodiments of the present application, continue to refer to Figure 2 As shown, the energy-saving heating and cooling dual-channel integrated machine also includes: a gas-liquid separator 500, and the low-pressure pipe group 320 includes: a cooling three-way valve 321 and an electronic expansion valve 322. The cooling three-way valve 321 has a cooling first end, a cooling second end and a cooling third end; one end of the electronic expansion valve 322 is connected to the liquid storage tank 332, and the other end is connected to the cooling first end, the cooling second end is connected to the cooling inlet end of the first cold heat exchanger 130, and the cooling third end is connected to the cooling outlet end of the air heat exchanger 400; the cooling outlet end of the first cold heat exchanger 130 is also connected to the gas-liquid separator 500, the gas-liquid separator 500 is connected to the air inlet end of the compressor 310, and the gas-liquid separator 500 is also connected to the cooling inlet end of the air heat exchanger 400.

[0078] Specifically, the gas-liquid separator 500 is used to separate the gas-liquid mixture of the refrigerant flowing out of the first cold-heat exchanger 130, ensuring that only the gaseous refrigerant enters the compressor 310 to prevent the liquid refrigerant from damaging the compressor. At the same time, it is connected to the air heat exchanger 400 through a bypass, providing an additional cooling or preheating opportunity for the refrigerant.

[0079] The refrigeration three-way valve 321 is used to switch the flow direction of the refrigerant according to the cooling or heating requirements of the system. In the cooling mode, the refrigerant flows to the first cold and heat exchanger 130 through the second cooling end; under certain conditions (such as when additional cooling is required), the refrigerant may flow to the air heat exchanger 400 through the third cooling end.

[0080] The electronic expansion valve 322 is used to control the flow of refrigerant entering the refrigeration cycle, thereby adjusting the system pressure and temperature and optimizing the refrigeration efficiency.

[0081] In this embodiment, a gas-liquid separator 500 is further added, and the composition of the low-pressure pipe group 320 is refined, which solves the technical problems of complex refrigerant management, insufficient protection of the compressor 310, and low system efficiency in the traditional heating and cooling system. The use of the gas-liquid separator 500 effectively avoids the damage of the liquid refrigerant to the compressor 310, and improves the stability and reliability of the system. At the same time, through the synergistic effect of the refrigeration three-way valve 321 and the electronic expansion valve 322, the flexible control of the refrigerant flow direction and the precise adjustment of the flow rate are achieved, and the efficiency of the refrigeration cycle is optimized.

[0082] In some embodiments of the present application, continue to refer to Figure 2 As shown, the air heat exchanger 400 is also provided with a fan 410 ; the fan 410 is configured to discharge the cold or heat entering the air heat exchanger 400 .

[0083] It is understandable that the main function of the fan 410 is to accelerate the flow of air in the air heat exchanger 400, thereby enhancing the heat exchange efficiency. It helps the air heat exchanger 400 to quickly discharge excess cold or heat. The fan 410 in this embodiment increases the flow rate of air in the air heat exchanger 400, thereby improving the rate and efficiency of heat exchange, helping the system to reach the required temperature in a shorter time and improving the overall energy efficiency.

[0084] In some embodiments of the present application, the energy-saving heating and cooling dual-channel integrated machine also includes: a temperature sensor group 600, the temperature sensor group 600 includes: a heating temperature sensor 610 and a cooling temperature sensor 620, and a control system electrically connected to the compressor 310, the heating three-way valve 331, the cooling three-way valve 321 and the temperature sensor group 600.

[0085] Among them, the heating temperature sensor 610 is arranged at the water outlet of the hot water tank 210 or the second heat exchanger 230, and the heating temperature sensor 610 is configured to: detect the hot water temperature to obtain hot water temperature data, and feed back to the control system; the cooling temperature sensor 620 is arranged near the water outlet of the cold water tank 110 or the first heat exchanger 130, and the cooling temperature sensor 620 is configured to: detect the cold water temperature to obtain cold water temperature data, and feed back to the control system.

[0086] The control system is configured to: receive hot water temperature data and cold water temperature data; when the hot water temperature data is higher than the preset upper limit of the heating temperature, and the cold water temperature data is higher than the preset lower limit of the cooling temperature, it is determined that excess heat needs to be discharged and a heat discharge operation is performed; when the cold water temperature data is lower than the preset lower limit of the cooling temperature, and the hot water temperature data is lower than the preset upper limit of the heating temperature, it is determined that excess cooling needs to be discharged and a cooling discharge operation is performed.

[0087] Specifically, the temperature sensor group 600 is used to monitor the temperature of hot water and cold water in real time, and feed the data back to the control system, providing a key basis for the energy management and heat discharge of the system. The control system analyzes the energy status of the system based on the received temperature data, and determines whether it is necessary to discharge excess heat or cold according to the preset upper and lower limits of the heating temperature and cooling temperature. The control system is also responsible for issuing control instructions to adjust the working status of components such as the compressor and the three-way valve to achieve energy balance.

[0088] When the hot water temperature is too high or the cold water temperature is too low, the control system can quickly identify and respond, and discharge heat by adjusting the working state of the system components, thereby avoiding energy waste and overheating or overcooling of the system. In this embodiment, the temperature sensor 600 monitors the temperature state of the system in real time, and the control system determines the energy demand of the system according to the preset temperature threshold, and realizes dynamic balance and efficient utilization of energy by adjusting the working state of components such as the compressor 310, the heating three-way valve 331, and the cooling three-way valve 321.

[0089] In some embodiments of the present application, the heat discharge operation is: controlling the heating three-way valve 331 to open, and controlling the cooling three-way valve 321 to close; the cold discharge operation is: controlling the cooling three-way valve 321 to open, and controlling the heating three-way valve 331 to close.

[0090] It is understandable that in the conventional heating mode, the heating three-way valve 331 directs hot water from the hot water tank 210 to the second cold heat exchanger 230 to heat the external medium (such as air or water). When performing heat discharge operation, the flow direction is switched to direct the hot water to the system external circulation pipeline to discharge excess heat through the air heat exchanger 400.

[0091] Specifically, when the control system detects that the hot water temperature data is higher than the preset upper limit of the heating temperature, it determines that the system has accumulated too much heat and needs to discharge the heat. At this time, the control system issues an instruction to control the heating three-way valve 331 to open, so that the hot water flows into the system's external circulation pipeline and discharges the heat to the outside through the air heat exchanger 400. At the same time, the cooling three-way valve 321 is controlled to be closed to avoid unnecessary loss of cooling capacity.

[0092] Furthermore, in the conventional cooling mode, the cooling three-way valve 321 directs cold water from the cold water tank 110 to the first cold heat exchanger 130 to cool the external medium. When performing the cold capacity discharge operation, the flow direction is switched to direct the cold water to the system external circulation pipeline, and the excess cold capacity is also released through the air heat exchanger 400.

[0093] Specifically, when the cold water temperature data is lower than the preset lower limit of the cooling temperature, indicating that the system has accumulated too much cooling capacity, the control system also issues a command, but this time it controls the cooling three-way valve 321 to open, so that the cold water flows into the system's external circulation pipeline, and may also start the fan 410 to release cooling capacity through the air heat exchanger 400. At the same time, the heating three-way valve 331 is controlled to be closed to ensure that heat does not enter the cold water circulation system.

[0094] In some embodiments of the present application, the control system is also electrically connected to the electronic expansion valve 322; the control system is also configured to: when the hot water temperature data is lower than the preset lower limit of the heating temperature, and the cold water temperature data is higher than the preset lower limit of the cooling temperature, it is determined that a cooling operation is required. The cooling operation is: controlling the cooling three-way valve 321 to open, controlling the heating three-way valve 331 to close, and opening the electronic expansion valve 322 to control the cooling flow.

[0095] The electronic expansion valve 322 controls the refrigeration capacity and efficiency of the refrigeration system by adjusting the refrigerant flow. In the refrigeration operation, the electronic expansion valve 322 accurately adjusts the refrigerant flow entering the first cold-heat exchanger 130 according to the instructions of the control system. By controlling the refrigerant flow, the electronic expansion valve 322 can quickly and accurately adjust the refrigeration capacity of the refrigeration system, thereby meeting different refrigeration needs.

[0096] Specifically, when the system needs to be cooled, the control system first determines whether the hot water temperature is lower than the lower limit of the heating temperature, and whether the cold water temperature is higher than the lower limit of the cooling temperature. If the conditions are met, the control system issues an instruction to control the cooling three-way valve 321 to open, so that the cold water in the cold water circulation system can flow through the first cold and heat exchanger 130 for cooling; at the same time, the heating three-way valve 331 is controlled to be closed to avoid unnecessary heat loss of hot water in the hot water circulation system. In addition, the control system also opens the electronic expansion valve 322 and adjusts its opening according to the cooling demand to accurately control the refrigerant flow entering the first cold and heat exchanger 130, thereby achieving fine adjustment of the cooling capacity.

[0097] In some embodiments of the present application, the temperature sensor group 600 also includes: a heat exchanger temperature sensor 630; the heat exchanger temperature sensor 630 is arranged inside the air heat exchanger 400, for detecting the temperature inside the air heat exchanger 400, obtaining heat exchanger temperature data, and feeding back to the control system; the control system is also configured to: receive the heat exchanger temperature data.

[0098] When the heating three-way valve 331 is opened and the cooling three-way valve 321 is closed, if the heat exchanger temperature data is higher than the preset heat discharge temperature, the fan 410 is controlled to be turned on to discharge excess heat entering the air heat exchanger 400. If the heat exchanger temperature data is lower than the preset heat discharge temperature, the fan 410 is controlled to be turned off; when the cooling three-way valve 321 is opened and the heating three-way valve 331 is closed, if the heat exchanger temperature data is lower than the preset cold discharge temperature, the fan 410 is controlled to be turned on to discharge excess cold entering the air heat exchanger 400. If the heat exchanger temperature data is higher than the preset cold discharge temperature, the fan 410 is controlled to be turned off.

[0099] In this embodiment, in the heating mode, when the heating three-way valve 331 is opened and the cooling three-way valve 321 is closed, the control system receives the heat exchanger temperature data fed back by the heat exchanger temperature sensor 630. If the data is higher than the preset heat discharge temperature, it indicates that too much heat has accumulated inside the air heat exchanger 400 and needs to be discharged faster. At this time, the control system issues an instruction to control the fan 410 to turn on to speed up the air flow and improve the heat discharge efficiency. If the heat exchanger temperature data is lower than the preset heat discharge temperature, the fan 410 is controlled to turn off to avoid unnecessary energy consumption.

[0100] Furthermore, in the cooling mode, when the cooling three-way valve 321 is opened and the heating three-way valve 331 is closed, the control system also makes a judgment based on the data fed back by the heat exchanger temperature sensor 630. If the data is lower than the preset cold discharge temperature, it indicates that too much cold has accumulated inside the air heat exchanger 400 and needs to be discharged faster. At this time, the control system issues an instruction to control the fan 410 to turn on. If the heat exchanger temperature data is higher than the preset cold discharge temperature, the fan 410 is controlled to turn off.

[0101] From the above content, it can be seen that after the energy-saving heating and cooling dual-channel integrated machine of this application is started, the temperature sensor group begins to monitor the temperature of each key part in real time, including the hot water temperature, the cold water temperature and the temperature inside the air heat exchanger. The control system receives and processes these temperature data, and judges the current working state of the system (heating or cooling) and whether it needs to be adjusted according to the preset logic. In the heating mode, that is, when the hot water temperature is lower than the preset lower limit of the heating temperature and the system judges that it is a heating demand, the control system opens the heating three-way valve and closes the cooling three-way valve. At the same time, the temperature inside the air heat exchanger is monitored. If it is higher than the preset heat discharge temperature, the fan is turned on to accelerate heat discharge.

[0102] In cooling mode: when the cold water temperature is higher than the preset lower limit of the cooling temperature and the system determines that there is a cooling demand, the control system opens the cooling three-way valve and closes the heating three-way valve. At the same time, the temperature inside the air heat exchanger is monitored. If it is lower than the preset cold discharge temperature, the fan is turned on to accelerate the cold discharge. In heating and cooling modes, the control system also accurately adjusts the flow of the refrigerant through the electronic expansion valve 322 (if applicable) to further control the cooling / heating capacity.

[0103] Through the above control method, in actual applications, when cooling the material tank and hydraulic station of the high-pressure foaming machine, the heat generated by the refrigeration components (such as the raw material tank and the hydraulic station, etc.) is collected and not directly discharged to the surrounding environment, but transferred to the heating component for heating the foaming fixture. Finally, the heat generated by the refrigeration component is transferred to the foaming fixture, which reduces the energy loss of the equipment and the heat discharged to the surrounding environment, thereby achieving the purpose of energy saving and carbon reduction. The energy-saving heating and cooling dual-channel integrated machine of this application can be used in production sites such as high-pressure foaming and blister forming that require heating and cooling at the same time. It has good practicality and is easy to promote.
