Description

Technical Field

[0001] This utility model relates to the technical field of four-phase cooling and heating unit, and in particular to a four-phase cooling and heating unit. Background Technology

[0002] In the fields of energy utilization and building environment control, traditional cooling, heating, domestic hot water supply, and power supply systems are often independent of each other. This decentralized system suffers from numerous problems, including low energy efficiency, large equipment investment, large footprint, and high operating costs. For example, traditional air conditioning systems are used for cooling, boiler systems for heating, water heaters for domestic hot water, and electricity is provided by the power grid or independent power generation equipment, lacking effective coordination and energy integration between the systems. With the increasing prominence of the energy crisis and environmental problems, people have placed higher demands on the efficient use of energy and sustainable development. At the same time, buildings have stricter standards for indoor comfort, safety, and economy. Against this backdrop, the quadruple-cooling and heating unit has emerged. It aims to integrate cooling, heating, domestic hot water supply, and power supply into one unit, achieving cascaded energy utilization and efficient system operation through optimized design and advanced control strategies.

[0003] Existing four-unit cooling and heating systems make it difficult for staff to visually assess the internal water conditions, such as water clarity or the presence of sediment. Furthermore, the filter plates are typically installed in complex locations within the water storage tank, making it difficult to directly observe their level of dirt during operation. Replacement is cumbersome, requiring significant time and manpower, severely impacting the unit's normal operation and maintenance efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a four-unit cooling and heating system.

[0005] This utility model is achieved using the following technical solution: a four-unit cooling and heating system, including an internal combustion engine, with a combustion inlet pipe fixedly connected to the top of the internal combustion engine, a generator connected to the right side of the internal combustion engine, a power distribution cabinet fixedly connected to the top of the generator, a double-pass waste heat pipe fixedly connected to the rear end of the internal combustion engine, an absorption chiller connected to the rear end of the double-pass waste heat pipe, a cooling tower fixedly connected to the top of the absorption chiller, a waste heat hot water boiler fixedly connected to the right side of the double-pass waste heat pipe, and a water storage tank provided at the front end of the waste heat hot water boiler.

[0006] The absorption chiller, as described above, includes an evaporator, a condenser, and a solution pump.

[0007] As a further improvement to the above solution, the waste heat hot water boiler is located to the left of the absorption chiller, and the inner surface of the water storage tank is provided with a groove.

[0008] As a further improvement to the above solution, a flue pipe is fixedly connected to the surface of the waste heat hot water boiler, a water inlet pipe is fixedly connected to the surface of the waste heat hot water boiler, a support base is fixedly connected to the bottom of the waste heat hot water boiler, a connecting pipe is fixedly connected to the surface of the waste heat hot water boiler, a heat exchanger is fixedly connected to the top of the connecting pipe, a circulating water pump is fixedly connected to the top of the heat exchanger, and a circulating pipe is fixedly connected to the surface of the top of the circulating water pump.

[0009] As a further improvement to the above scheme, the circulation pipe is connected to a heat exchanger.

[0010] Through the above technical solution, the circulation pipeline is connected to the heat exchanger to form a circulation path for the heating medium. The heating medium, which has been heated by the heat exchanger, is transported to the user end, and then the low-temperature return water is brought back to the heat exchanger to complete the circulation.

[0011] As a further improvement to the above solution, a cover plate is inserted into the inner wall of the water storage tank, a rotating rod is threaded into the inside of the cover plate, an insert plate is slidably connected to the inner wall of the cover plate, a connecting plate is fixedly connected to the bottom of the cover plate, and a filter plate is fixedly connected to the bottom of the connecting plate.

[0012] Through the above technical solution, the rotating rod is connected to the internal thread of the cover plate. When rotating, the insertion and removal of the insert plate can be controlled, thereby realizing the convenient connection and separation of the cover plate and the water storage tank.

[0013] As a further improvement to the above solution, the water storage tank is fixedly connected to the water inlet pipe.

[0014] As a further improvement to the above solution, the bottom of the cover plate is provided with a groove, one end of the insert plate is provided with a groove, and the insert plate is inserted into the internal groove of the water storage tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention, by incorporating an internal combustion engine, cleverly integrates power generation, cooling, heating, and domestic hot water supply functions into a single unit. When the internal combustion engine operates, the chemical energy of the fuel is converted into mechanical energy to drive the generator. Simultaneously, the waste heat generated is transported via dual-pass waste heat pipes to an absorption chiller for refrigeration and a waste heat hot water boiler for heating and domestic hot water production. This achieves cascaded energy utilization, significantly improving the overall energy efficiency and substantially reducing energy consumption and operating costs compared to traditional independent energy supply systems.

[0017] This invention features a rotating rod that allows for flexible control of the insertion and connection of the filter plate into the water storage tank groove. This facilitates easy removal of the cover plate containing the filter plate, enabling staff to readily inspect the water quality inside the tank, determine if it meets standards, and promptly remove impurities. Simultaneously, it allows for direct visualization of the filter plate's dirt level, enabling quick and convenient filter plate replacement. This ensures the quality of water entering the waste heat boiler, extends equipment lifespan, reduces malfunctions caused by water quality issues, and improves the overall unit's operational stability and maintenance efficiency.

A distribution cabinet 4 is fixedly connected to the top of the generator 3. A double-pass waste heat pipe 5 is fixedly connected to the rear end of the internal combustion engine 1. An absorption chiller 6 is connected to the rear end of the double-pass waste heat pipe 5. A cooling tower 601 is fixedly connected to the top of the absorption chiller 6. A waste heat hot water boiler 7 is fixedly connected to the right side of the double-pass waste heat pipe 5. A water storage tank 8 is installed at the front end of the waste heat hot water boiler 7. Fuel enters the internal combustion engine 1 through the combustion inlet pipe 2 for combustion, driving the generator 3 to generate electricity. The electrical energy is distributed and used by the distribution cabinet 4. Part of the waste heat generated by the internal combustion engine 1 is transported to the absorption chiller 6 through the double-pass waste heat pipe 5. The evaporator, condenser, and solution pump inside the absorption chiller 6 work together to achieve cooling, and the generated heat is dissipated by the top cooling tower 601. The other part of the waste heat enters the waste heat hot water boiler 7. External water enters the water storage tank 8, is filtered by the filter plate 805, and then flows into the waste heat hot water boiler 7 through the water inlet pipe 702. After being heated, it is transported to the heat exchanger 705 through the connecting pipe 704. The circulating water pump 706 drives the water in the circulating pipe 707 to exchange heat with the heat exchanger 705 to achieve heating.

[0028] The waste heat hot water boiler 7 is located to the left of the absorption chiller 6, and the inner surface of the water storage tank 8 is provided with grooves.

[0029] The waste heat hot water boiler 7 has a flue pipe 701 fixedly connected to its surface, a water inlet pipe 702 fixedly connected to its surface, a support base 703 fixedly connected to its bottom, a connecting pipe 704 fixedly connected to its surface, a heat exchanger 705 fixedly connected to the top of the connecting pipe 704, a circulating water pump 706 fixedly connected to the top of the heat exchanger 705, and a circulating pipe 707 fixedly connected to the top surface of the circulating water pump 706.

[0030] The circulation pipe 707 is connected to the heat exchanger 705.

[0031] A cover plate 801 is inserted into the inner wall of the water storage tank 8. A rotating rod 802 is threaded into the inside of the cover plate 801. An insert plate 803 is slidably connected to the inner wall of the cover plate 801. A connecting plate 804 is fixedly connected to the bottom of the cover plate 801. A filter plate 805 is fixedly connected to the bottom of the connecting plate 804. By rotating the rotating rod 802, the insertion of the insert plate 803 into the groove of the water storage tank 8 is controlled. At the same time, the insert plate 803 slides inside the cover plate 801, which makes it convenient to disassemble the cover plate 801 to check the filter plate 805 and the water source in the water tank.

[0032] The water storage tank 8 is fixedly connected to the water inlet pipe 702.

[0033] The bottom of the cover plate 801 has a groove, and one end of the insert plate 803 has a groove. The insert plate 803 is inserted into the groove inside the water storage tank 8.

[0034] The implementation principle of a four-unit combined cooling and heating system in this application embodiment is as follows: Fuel enters the internal combustion engine 1 through the combustion pipe 2 for combustion, driving the generator 3 to generate electricity, which is then distributed and used by the distribution cabinet 4. The waste heat generated by the internal combustion engine 1 is partially transported to the absorption chiller 6 through the double-pass waste heat pipe 5. The evaporator, condenser, and solution pump inside the absorption chiller work together to achieve cooling, and the generated heat is dissipated by the top cooling tower 601. The other part of the waste heat enters the waste heat hot water boiler 7. External water enters the water storage tank 8, is filtered by the filter plate 805, and then flows into the waste heat hot water boiler 7 through the inlet pipe 702. After being heated, it is transported to the heat exchanger 705 through the connecting pipe 704. The circulating water pump 706 drives the water in the circulating pipe 707 to exchange heat with the heat exchanger 705 to achieve heating. The insertion of the insert plate 803 into the groove of the water storage tank 8 can be controlled by rotating the rotating rod 802. Simultaneously, the insert plate 803 slides inside the cover plate 801, facilitating the removal of the cover plate 801 to inspect the filter plate 805 and the water source in the water tank.
