Description

Technical Field

[0001] The present invention relates to the field of heat exchange technology, and in particular to a full heat exchanger that uses water as a medium for efficient energy transfer and conversion, and is suitable for occasions requiring energy recovery, such as building ventilation systems and air-conditioning systems. Background Art

[0002] Traditional heat exchangers primarily use thin metal sheets as the heat exchange medium, achieving energy exchange through direct heat conduction between the return and incoming air. However, due to the small density difference between the gases and the fact that heat transfer efficiency is limited by material properties, traditional heat exchangers have low heat exchange efficiencies, typically only around 70%, making it difficult to maximize energy utilization. Furthermore, the metal medium is susceptible to corrosion over long-term use, impacting equipment life and heat exchange performance. Summary of the Invention

[0007] The second water tank is provided with an air inlet and an air outlet. The air inlet of the second water tank is connected to the air outlet of the first water tank and is used to receive the air processed by the first water tank. The air outlet of the second water tank sends the air after adjusting the temperature into the room.

[0008] The return air chamber in the first water tank is connected to the bottom of the outdoor fresh air inlet chamber in the first water tank, thereby realizing the free flow of water and energy transfer in the left and right air chambers.

[0009] Furthermore, the first and second water tanks are made of corrosion-resistant materials with good thermal conductivity, including stainless steel, engineering plastics or composite materials.

[0010] Furthermore, there is a significant temperature difference between the temperature of the water in the first water tank and the fresh air entering the first water tank to promote efficient heat exchange; the temperature of the water in the second water tank is adjusted according to seasonal changes to provide air of suitable temperature to the room.

[0011] A heat exchange method for a full heat exchanger comprises the following steps:

[0012] Energy absorption step: the return gas enters through the return air port of the first water tank return air chamber, exchanges heat with the water in the first water tank return air chamber, and its cold energy or heat energy is absorbed and stored by the water;

[0013] Energy transfer step: The energy absorbed and stored in the return air chamber of the first water tank is transferred to the outdoor fresh air intake chamber through the water channel at the bottom of the tank, and at the same time, the energy in the first water tank is transferred to the second water tank through the water tank connecting device;

[0014] Energy conversion and release steps: Outdoor fresh air enters through the air inlet of the fresh air inlet chamber of the first water tank, undergoes the first heat exchange with the water in the fresh air chamber of the first water tank, thereby absorbing and converting the cold energy or heat energy absorbed and stored in the water through the return air chamber of the first water tank, and then enters the second water tank through the air outlet of the first water tank, undergoes the second heat exchange with the temperature-adjusted water in the second water tank, and after obtaining the appropriate temperature, is sent into the room through the air outlet of the second water tank.

[0024] Example:

[0025] The full heat exchanger proposed in this invention mainly includes the following core components and working principles:

[0026] Water tank structure:

[0027] The first water tank: is divided into a return air chamber 100 and an outdoor fresh air intake chamber 200. A return air port 1 and an exhaust port 2 are provided above the return air chamber 100. The return air port 1 is used to receive the gas with cold energy (in summer) or heat energy (in winter) that flows back from the indoor to the outdoor; an air inlet 3 and an air outlet 4 are provided above the outdoor fresh air intake chamber 200. The air inlet 3 is connected to the outdoor fresh air source; the air outlet 4 is connected to the air inlet 5 of the second water tank. The return air chamber 100 in the first water tank is connected to the bottom of the fresh air intake chamber 200 in the first water tank, which realizes the free flow of water and energy transfer in the left and right air chambers, ensures the efficient conversion of recovered energy, and achieves the purpose of high energy saving.

[0028] The second water tank is provided with an air inlet 5 and an air outlet 6. The air inlet 5 is connected to the air outlet 4 of the first water tank to receive the air processed by the first water tank; the air outlet 6 sends the conditioned air into the room.

[0029] Working principle:

[0030] Energy absorption stage: The return gas enters through the return air port of the first water tank return air chamber and exchanges heat with the water in the water tank. Since the density of water is much greater than that of gas (about 3000 times), and there is a large temperature difference between the water temperature in the water tank and the incoming fresh air, the energy (cold energy or heat energy) of the return gas is quickly and massively absorbed by the water.

[0031] Energy conversion and storage stage: The energy absorbed by the return air chamber of the first water tank is transferred to the fresh air chamber through the water channel at the bottom of the tank, and is also transferred to the second water tank through the connecting pipe, so that the water temperature in the second water tank increases or decreases accordingly, and the cold energy or heat energy required for fresh air is stored;

[0032] Energy conversion and release steps: Outdoor fresh air enters through the air inlet of the fresh air inlet chamber of the first water tank, undergoes the first heat exchange with the water in the fresh air chamber of the first water tank, thereby absorbing and converting the cold energy or heat energy absorbed and stored in the water through the return air chamber of the first water tank, and then enters the second water tank through the air outlet of the first water tank, undergoes a second heat exchange with the temperature-adjusted water in the second water tank, and after obtaining the appropriate temperature, is sent into the room through the air outlet of the second water tank, thereby realizing efficient energy utilization.

[0033] The present invention breaks through the limitation of low heat exchange efficiency of traditional full heat exchangers. By utilizing the high density and good thermal conductivity of water, it can theoretically approach or achieve 100% energy utilization, effectively improving energy saving effects. The equipment has a simple structure, is corrosion-resistant, and operates stably. It is suitable for energy recovery scenarios such as building ventilation and air-conditioning systems, achieving the best energy-saving and environmental protection goals.

[0034] The present invention and its embodiments are described above. This description is not restrictive.

In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
