Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection and energy-saving equipment, in particular to a heat exchange station for household central heating. Background Art

[0002] In the existing technology, the home central heating system is usually centrally controlled by the heating company, which means that the heating time and temperature of all users are uniformly adjusted by the heating company, resulting in users being unable to adjust the indoor temperature according to their personal needs and preferences. This centralized control method often leads to some major problems:

[0003] Due to the uniformity of heating time and temperature, when some users need higher or lower temperatures, they cannot be satisfied. This may cause users to feel overheated or overcooled indoors, affecting the comfort of living. During the period when heating is not needed, users may experience unnecessary heating due to the unified operation of the system, resulting in energy waste. Similarly, in the non-heating season, such as during the spring and autumn seasons, when the weather suddenly turns cold, the central heating system has not yet started, and residents can only endure the cold and cannot get timely heating supply. Central heating usually only operates during the heating season, which means that in the non-heating season, even if the temperature drops sharply, users cannot get heating, which greatly reduces the practicality and flexibility of the heating system. Existing central heating systems often lack a regulation mechanism to quickly respond to climate change or changes in personal needs. Once the heating plan is formulated, it is difficult to make adjustments according to actual conditions, which is particularly inconvenient in areas with variable climate changes. Due to the wide coverage of the central heating system, individual households may have to wait for a long time to be resolved when encountering heating problems. In addition, system upgrades or maintenance may affect the heating effect of the entire area. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of the utility model is to provide a heat exchange station for household central heating, so as to solve the problems of poor controllability and neglect of personalized needs of existing household central heating systems, as well as limitations in the non-heating season, which often cause users to face inconvenience and discomfort.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A heat exchange station for household central heating, characterized in that it includes a plate heat exchanger, an expansion water tank, an exhaust valve, a circulating pump, a pressure-temperature display gauge and a pressure relief valve. A primary heating water inlet and a primary heating water outlet are arranged on one side of the plate heat exchanger, and a household heating water inlet and a household heating water outlet are arranged on the other side of the plate heat exchanger. The exhaust valve, circulating pump, pressure-temperature display gauge and pressure relief valve are arranged in sequence on the pipeline where the household heating water outlet is located. The circulating pump is connected to the expansion water tank through a pipeline, and the primary heating water inlet and the primary heating water outlet are connected to the primary central heating water inlet and outlet circulation port and the primary wall-mounted boiler heating water inlet and outlet through a pipeline.

[0007] The preferred technical solution also includes an external shell, and the plate heat exchanger, expansion water tank, exhaust valve, circulation pump, pressure and temperature display gauge and pressure relief valve are integrated inside the external shell.

[0008] According to a preferred technical solution, four interfaces are arranged on the outer shell, and the four interfaces respectively correspond to the positions of the primary heating water inlet, the primary heating water outlet, the household heating water inlet and the household heating water outlet.

[0009] According to a preferred technical solution, the outer shell is provided with two operation observation ports, which respectively correspond to the positions of the pressure relief valve and the pressure and temperature display gauge.

[0010] According to a preferred technical solution, the volume of the expansion water tank is 6-10L.

[0019] A heat exchange station for household central heating, characterized in that it includes a plate heat exchanger 1, an expansion water tank 2, an exhaust valve 3, a circulating pump 4, a pressure and temperature display gauge 5 and a pressure relief valve 6. A primary heating water inlet 7 and a primary heating water outlet 8 are provided on one side of the plate heat exchanger 1, and a household heating water inlet 9 and a household heating water outlet 10 are provided on the other side of the plate heat exchanger 1. The exhaust valve 3, the circulating pump 4, the pressure and temperature display gauge 5 and the pressure relief valve 6 are sequentially arranged on the pipeline where the household heating water outlet 10 is located. The circulating pump 4 is connected to the expansion water tank 2 through a pipeline. The primary heating water inlet 7 and the primary heating water outlet 8 are connected to the primary central heating water inlet and outlet circulation port and the primary wall-mounted boiler heating inlet and outlet through a pipeline.

[0020] It also includes an external shell 11, and the plate heat exchanger 1, the expansion water tank 2, the exhaust valve 3, the circulation pump 4, the pressure and temperature display gauge 5 and the pressure relief valve 6 are integrated inside the external shell 11. The outer shell 11 is provided with four interfaces 12, and the four interfaces 12 correspond to the positions of the primary side heating water inlet 7, the primary side heating water outlet 8, the household heating water inlet 9 and the household heating water outlet 10.

[0021] The utility model technology realizes an integrated household central heating heat exchange station through components such as built-in circulation pump 4, plate heat exchanger 1, expansion water tank 2, exhaust valve 3, pressure and temperature display meter 5, etc., aiming to solve the problems of poor comfort and energy saving of household heating. Plate heat exchanger 1 is the core component, and plate heat exchanger 1 is responsible for transferring heat energy from the primary side (central heating or wall-mounted boiler) to the secondary side (household heating system). By increasing the heat exchange area, efficient energy conversion is achieved. Expansion water tank 2 is used to compensate for the expansion of water during heating to prevent the system pressure from being too high, and to replenish the system water volume when the water is cooled to avoid negative pressure. The air in the system is automatically removed to ensure unimpeded flow of hot water and improve heat exchange efficiency. Circulation pump 4 promotes hot water to circulate in the system to ensure that heat is evenly distributed to every corner of the home. Pressure and temperature display meter 5 monitors the pressure and temperature of the system in real time, which is convenient for users to understand and adjust the state of home heating. Pressure relief valve 6 automatically opens when the system pressure exceeds the safety value to release the pressure and protect the system from damage.

[0022] The working process of the utility model is as follows:

[0023] Start-up phase: When the family needs heating, the circulation pump starts to push the hot water heated by central heating or wall-mounted boiler to flow through the plate heat exchanger.

[0024] Heat exchange process: The hot water transfers heat to the water in the home heating system in the plate heat exchanger, achieving effective utilization of thermal energy.

[0025] Adjustment and control: Users can adjust the running speed of the circulation pump and the working status of the wall-mounted boiler through the control system according to the readings of the pressure and temperature display gauge to achieve the ideal indoor temperature.

[0026] Safety protection: If the system pressure is too high, the pressure relief valve will automatically open to reduce the pressure and ensure safe and stable operation of the system.

[0027] Improved comfort: Even in the non-central heating season, users can start the wall-mounted boiler and provide the heating required by the family through the heat exchange station to achieve a comfortable indoor environment all year round.

[0028] Maintenance and monitoring: The operation observation port set on the shell body allows users to monitor and maintain the pressure relief valve and pressure and temperature display gauge to ensure long-term stable operation of the system.

[0029] Through the above working principle and working process, the technology of the utility model significantly improves the comfort of home heating, reduces energy consumption, and realizes the user's personalized control of heating time and temperature.
