[0002] In industrial production and daily life, many devices and systems require precise control of fluid temperature and flow direction. With the continuous advancement of technology and the increasing demands of people for quality of life and production efficiency, the demand for equipment that can simultaneously achieve cooling and heating functions and has the characteristics of rapid switching and precise control is growing.

[0003] Traditional temperature control equipment typically uses a single pipe to supply power to either the refrigeration or heating device. After prolonged use, blockages can easily occur inside the pipe, requiring the equipment to be stopped for repairs, which increases downtime. Furthermore, the existing adjustment structure, which relies on complex piping systems and control valves, is too complicated to meet the demands for rapid switching and precise temperature control. Utility Model Content

The first main pipe is connected to the solenoid valve body, and the solenoid valve body is connected to the second main pipe. The second main pipe is connected to the second branch pipe, and one end of the second branch pipe is the connecting pipe, and the other end is the second maintenance pipe.

[0007] The main pipeline 1 and the branch pipeline 1 form a three-way pipeline structure, and the branch pipeline 1 is connected to the bypass valve. The bypass valve is connected to the branch pipeline 2, and the branch pipeline 2 and the main pipeline 2 form a three-way pipeline structure.

[0008] By adopting the above technical solution, the branch pipeline structure where the bypass valve is located can flexibly adjust the refrigerant flow and pressure, thereby optimizing the system operating efficiency.

[0009] Preferably, the compressor is connected to the evaporator via a pipe, and the evaporator, expansion valve, and condenser are connected via pipes.

[0010] By adopting the above technical solution, the pipe connection relationship between the compressor, evaporator, expansion valve and condenser is determined to ensure that the refrigerant can flow in the system according to the predetermined circulation path, and to ensure that the cooling and heating functions are realized normally.

[0011] Preferably, both the first and second branch pipes are three-way pipe structures, and the maintenance pipe of the first branch pipe is fitted with a valve.

[0012] By adopting the above technical solution, the three-way pipe structure of the first and second branch pipes and the sealing valve inside the maintenance pipe 1 ensure the normal distribution of refrigerant while providing a convenient interface for system maintenance, allowing for quick pressure testing or refrigerant charging.

[0013] Preferably, the inner diameter of the first main pipe is the same as the inner diameter of the second main pipe.

[0014] By adopting the above technical solution, the diameters of main pipe one and main pipe two are the same, which can reduce the resistance loss of refrigerant flow in the pipe, maintain a stable flow rate and pressure, and improve the system's operational stability and energy efficiency.

[0016] Using the above technical solution, pressure sensors on main pipeline one and main pipeline two are electrically connected to the compressor to monitor pipeline pressure in real time and provide timely feedback to the compressor to adjust its operating status, thereby avoiding equipment damage due to abnormal pressure and ensuring the safe and stable operation of the system.

[0017] Preferably, a valve is fitted inside the maintenance access pipe of the second branch pipe, and the connecting pipe of the second branch pipe is connected to the pipe of the condenser.

[0018] By adopting the above technical solution, the connecting pipe is connected to the condenser pipe to ensure that the refrigerant can smoothly enter the condenser for heat exchange and realize the cooling and heating functions.

[0019] Preferably, the bypass valve is connected to the main pipeline by a branch pipeline one, and the bypass valve is connected to the main pipeline by a branch pipeline two.

[0023] 2. Furthermore, the bypass valve in the device is connected to the main pipeline through branch pipeline one and to the main pipeline two through branch pipeline two. During system maintenance, the bypass valve is adjusted to allow some or all of the fluid to circulate through the bypass, thereby isolating the main pipeline one, main pipeline two, and related components. This facilitates maintenance of specific areas without affecting the normal operation of other parts, improving the flexibility and safety of maintenance, reducing the flow in the main circulation, reducing the workload of the compressor, avoiding frequent start-ups and shutdowns of the equipment, further improving energy efficiency, and also reducing equipment wear and extending the service life of the equipment.

[0031] 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.

[0032] Please see Figures 1-6 This utility model provides a technical solution: a solenoid valve dual-purpose cooling and heating machine, including a compressor 1, a condenser 2, a first branch pipe 3, a first maintenance pipe 4, a first main pipe 5, a solenoid valve body 6, a second main pipe 7, a second branch pipe 8, a connecting pipe 9, a second maintenance pipe 10, a first branch pipe 11, a bypass valve 12, a second branch pipe 13, an expansion valve 14, and an evaporator 15;

[0033] Among them, compressor 1 is one of the main components of the dual-purpose cooling and heating machine, and compressor 1, condenser 2, expansion valve 14 and evaporator 15 together are the main equipment of the dual-purpose cooling and heating machine;

[0034] The output end of compressor 1 is connected to branch pipe 3, one end of which is service access pipe 4, and the other end is the main pipe 5. Both branch pipe 3 and branch pipe 8 are tee pipe structures. A valve is engaged within service access pipe 4 of branch pipe 3. The main pipe 5 is connected to the solenoid valve body 6, and the solenoid valve body 6 is connected to the main pipe 7. The main pipe 7 is connected to branch pipe 8, one end of which is a connecting pipe 9, and the other end is service access pipe 10. Compressor 1 is connected to evaporator 15 through pipes. Evaporator 15, expansion valve 14, and condenser 2 are connected through pipes. A valve is engaged within service access pipe 10 of branch pipe 8, and the connecting pipe 9 of branch pipe 8 is connected to the pipe of condenser 2. Service access pipe 4 and service access pipe 10 are also connected.

[0035] Referring to the attached diagrams in the instruction manual Figures 1-6As shown, when the device starts in cooling mode, compressor 1, acting as a power source, compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. The compressed high-temperature, high-pressure gaseous refrigerant enters the distributor pipe 3 from the output of compressor 1. Distributor pipe 3 divides the refrigerant into two parts. One part accumulates in maintenance pipe 4, but during normal cooling operation, the valve in maintenance pipe 4 is closed, and most of the refrigerant flows through main pipe 5 to the solenoid valve body 6. At this time, the solenoid valve body 6 is open, allowing the refrigerant to pass smoothly. The refrigerant enters main pipe 7, and the refrigerant in main pipe 7 flows to distributor pipe 8. Due to the valve in maintenance pipe 10... When the compressor is closed, the refrigerant enters the condenser 2 through the connecting pipe 9. In the condenser 2, the high-temperature and high-pressure gaseous refrigerant exchanges heat with the external environment, releases heat, and gradually condenses into high-pressure liquid refrigerant. After the high-pressure liquid refrigerant flows out of the condenser 2, it passes through the expansion valve 14. The expansion valve 14 throttles and reduces the pressure of the refrigerant, making it a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant enters the evaporator 15, where it absorbs heat from the surrounding environment and evaporates into a low-temperature and low-pressure gaseous refrigerant. At this time, the temperature of the surrounding environment decreases, achieving a cooling effect. The low-temperature and low-pressure gaseous refrigerant coming out of the evaporator 15 flows back to the compressor 1 through the pipe, completing one refrigeration cycle.

[0036] Main pipe 15 and branch pipe 11 form a three-way pipe structure, and branch pipe 11 is connected to bypass valve 12. Bypass valve 12 is connected to branch pipe 2 13, and branch pipe 2 13 and main pipe 2 7 form a three-way pipe structure. The inner diameter of main pipe 15 and main pipe 2 7 are the same. Pressure sensors are fixedly installed on both main pipe 15 and main pipe 2 7, and the pressure sensors are connected to compressor 1 through electrical signals. Bypass valve 12 is connected to main pipe 15 through branch pipe 11, and by bypass valve 12 is connected to main pipe 2 7 through branch pipe 2 13.

[0037] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, when the device requires heating mode, compressor 1 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant, which then enters the expansion valve 14 from the pipe connecting compressor 1 to evaporator 15. Figure 6 As shown, at this time, the fluid flows in reverse, so that the component that originally served as condenser 2 in the cooling mode becomes an evaporator in the heating mode, and the component that originally served as evaporator 15 becomes a condenser in the heating mode. The high-temperature and high-pressure gaseous refrigerant enters the original evaporator 15, releases heat to heat the surrounding environment, and realizes the heating function. Afterwards, the refrigerant enters the original condenser 2 after being depressurized by the expansion valve 14. At this time, it serves as evaporator 15, absorbs external heat, and then flows back to the compressor 1 to complete the heating cycle.

[0038] In this device, the added bypass pipe is opened through the bypass valve 12 during the maintenance of the solenoid valve body 6. The fluid in the main pipe 1 5 enters the bypass valve 12 through the branch pipe 11, and then flows back to the main pipe 2 7 through the branch pipe 2 13, thus completing the fluid flow.

[0039] During this period, the pressure sensors of main pipeline 5 and main pipeline 7 monitor the pressure in the pipeline in real time. When the pressure in the pipeline exceeds the set safety threshold, the pressure sensor will transmit an electrical signal to compressor 1. After receiving the signal, compressor 1 will make corresponding adjustments according to the preset program, such as reducing the compression power and pausing work, to avoid damage to the system due to excessive pressure and ensure the safe and stable operation of the equipment.

[0040] Working principle: When using this solenoid valve dual-purpose cooling and heating machine, this device has two modes. In the cooling mode, the compressor 1 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous state. It passes through the first branch pipe 3. Since the valve of the maintenance pipe 4 is closed, most of the refrigerant flows along the main pipe 5, through the open solenoid valve body 6, to the second main pipe 7. At this time, the valve of the second maintenance pipe 10 is closed, and then it enters the condenser 2 through the second branch pipe 8 to release heat and condense. The liquid refrigerant is throttled and depressurized by the expansion valve 14, and then absorbs heat and evaporates in the evaporator 15. The low-temperature, low-pressure gaseous refrigerant flows back to the compressor 1, completing the refrigeration cycle.

[0041] When the device is in heating mode, the fluid in the compressor 1 enters the evaporator 15, causing the refrigerant to flow back to the compressor 1, thereby achieving heating. During this period, the pressure sensors on the main pipe 1 5 and the main pipe 2 7 monitor the pressure in real time. When the pressure exceeds the safety threshold, an electrical signal is transmitted to the compressor 1, and the compressor 1 adjusts according to the preset program to ensure the safety and stability of the equipment and increase the overall practicality.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
