Description

Technical Field

[0001] The utility model relates to the technical field of heating equipment, in particular to a hybrid heating device for energy-saving and non-energy-saving buildings. Background Art

[0002] In the development of heating, in order to meet the heating needs of different customers, it often occurs that an energy-saving building and a non-energy-saving building share a heat exchange station for heating. Generally, floor heating is used in energy-saving buildings, and radiators are used in non-energy-saving buildings. Therefore, the secondary network heating temperatures required by the two types of buildings are different. Usually, the secondary network water supply temperature required by energy-saving buildings is 3-5 degrees Celsius lower than that of non-energy-saving buildings. However, since the secondary network water supply temperature of the heat exchange station is the same, the following problems are likely to occur: the room temperatures of users in the same area vary greatly, and the user experience is poor; the secondary network temperature balance is out of balance, resulting in energy waste. Content of the Utility Model

[0003] The purpose of the utility model is to provide a hybrid heating device for energy-saving and non-energy-saving buildings to solve the above problems.

[0004] The utility model realizes the above purpose through the following technical solutions:

[0005] A hybrid heating device for energy-saving and non-energy-saving buildings includes a secondary network water supply line and a secondary network water return line. The secondary network water supply line includes an energy-saving water supply branch pipe and an energy-saving water return branch pipe. The water in the energy-saving water supply branch pipe flows into the energy-saving building, and the water in the energy-saving building flows out through the energy-saving water return branch pipe. A mixing water pump is installed between the energy-saving water supply branch pipe and the energy-saving water return branch pipe. The outlet end of the mixing water pump is communicated with the energy-saving water supply branch pipe, and the inlet end of the mixing water pump is communicated with the energy-saving water return branch pipe. Ball valves are arranged on both the inlet end and the outlet end of the mixing water pump.

[0006] Preferably, the secondary network water supply line further includes a secondary network water supply main pipe and a water distributor. The inlet end of the water distributor is communicated with the secondary network water supply main pipe, and the outlet end of the water distributor is communicated with the energy-saving water supply branch pipe.

[0007] Preferably, the secondary network water supply line further includes a non-energy-saving water supply branch pipe. The outlet end of the water distributor is communicated with the non-energy-saving water supply branch pipe, and the water in the non-energy-saving water supply branch pipe flows into the non-energy-saving building.

[0008] Preferably, the secondary network water return line further includes a secondary network water return main pipe and a water collector. The outlet end of the water collector is communicated with the secondary network water return main pipe, and the inlet end of the water collector is communicated with the energy-saving water return branch pipe.

[0009] Preferably, the secondary network water return line further includes a non-energy-saving water return branch pipe. The inlet end of the water collector is communicated with the non-energy-saving water return branch pipe, and the water in the non-energy-saving building flows out through the non-energy-saving water return branch pipe.

[0010] The beneficial effects are as follows: A mixing water pump is arranged between the energy-saving water supply branch pipe and the energy-saving water return branch pipe. The mixing water pump pumps the water in the energy-saving water return branch pipe into the energy-saving water supply branch pipe. Since the water in the energy-saving water return branch pipe is at a relatively low temperature, the water temperature in the energy-saving water supply branch pipe is reduced. On the premise of ensuring the same water supply temperature of the heat exchange station, the water supply temperature in the energy-saving building is lower than that in the non-energy-saving building, reducing the difference in room temperature among users in the same area, improving the user experience, and keeping the secondary network water supply temperature within a relatively balanced range, reducing energy waste.

The secondary network water supply line includes an energy-saving water supply branch pipe 5 and an energy-saving water return branch pipe 6. The water in the energy-saving water supply branch pipe 5 flows into the energy-saving building. After heat exchange in the building, the cold water in the energy-saving building flows out through the energy-saving water return branch pipe 6. A mixing water pump 7 is installed between the energy-saving water supply branch pipe 5 and the energy-saving water return branch pipe 6. The water outlet end of the mixing water pump 7 is connected to the energy-saving water supply branch pipe 5, and the water inlet end of the mixing water pump 7 is connected to the energy-saving water return branch pipe 6. Ball valves 8 are provided at both the water inlet end and the water outlet end of the mixing water pump 7. The cold water in the energy-saving water return branch pipe 6 is pumped back into the energy-saving water supply branch pipe 5 by the mixing water pump 7, so that the water temperature in the energy-saving water supply branch pipe 5 is reduced, thereby reducing the secondary network water supply temperature of the energy-saving building.

[0019] The secondary network water supply line further includes a secondary network water supply main pipe 1 and a water distributor 3. The secondary network water supply main pipe 1 is connected to the water outlet end of the heat exchange station. The water inlet end of the water distributor 3 is connected to the secondary network water supply main pipe 1, and the water outlet end of the water distributor 3 is connected to the energy-saving water supply branch pipe 5. The hot water from the heat exchange station enters the water distributor 3 through the secondary network water supply main pipe 1, and then enters the energy-saving building through the energy-saving water supply branch pipe 5. The secondary network water supply line further includes a non-energy-saving water supply branch pipe 9. The water outlet end of the water distributor 3 is connected to the non-energy-saving water supply branch pipe 9. The water in the non-energy-saving water supply branch pipe 9 flows into the non-energy-saving building. The hot water in the heat exchange station is respectively introduced into the energy-saving building and the non-energy-saving building through the energy-saving water supply branch pipe 5 and the non-energy-saving water supply branch pipe 9.

[0020] The secondary network water return line further includes a secondary network water return main pipe 2 and a water collector 4. The secondary network water return main pipe 2 is connected to the return end of the heat exchange station. The water outlet end of the water collector 4 is connected to the secondary network water return main pipe 2, and the water inlet end of the water collector 4 is connected to the energy-saving water return branch pipe 6. The cold water after heat exchange flows back into the water collector 4 through the energy-saving water return branch pipe 6, and then flows back to the heat exchange station through the secondary network water return main pipe 2. The secondary network water return line further includes a non-energy-saving water return branch pipe 10. The water inlet end of the water collector 4 is connected to the non-energy-saving water return branch pipe 10. The water in the non-energy-saving building flows out through the non-energy-saving water return branch pipe 10. The cold water flowing out of the energy-saving building and the cold water flowing out of the non-energy-saving building are respectively introduced into the water collector 4 through the energy-saving water return branch pipe 6 and the non-energy-saving water return branch pipe 10.

[0021] Working principle: The hot water in the heat exchange station is introduced into the water distributor 3 through the secondary network water supply main pipe 1. The hot water in the water distributor 3 is respectively introduced into the energy-saving building and the non-energy-saving building through the energy-saving water supply branch pipe 5 and the non-energy-saving water supply branch pipe 9. After heat exchange, the cold water flows back to the water collector 4 through the energy-saving water return branch pipe 6 and the non-energy-saving water return branch pipe 10, and then flows back to the heat exchange station through the secondary network water return main pipe 2. The cold water in the energy-saving water return branch pipe 6 is pumped into the energy-saving water supply branch pipe 5 by the mixing water pump 7, so that the water temperature in the energy-saving water supply branch pipe 5 is reduced. Under the condition of ensuring the same water supply temperature of the heat exchange station, the water supply temperature in the energy-saving building is lower than that in the non-energy-saving building, reducing the difference in the room temperature of users in the same area, improving the user experience, and keeping the secondary network water supply temperature within a relatively balanced range, reducing energy waste.
