Description

Technical Field

[0001] The present application relates to the technical field of hot water regulation and control systems, and in particular to a high-efficiency and energy-saving centralized regulation system for hot water for bathing. Background Art

[0002] At present, the hot water regulation system for bathing in hotels, residences or schools usually uses air source heat pumps and hot water circulation pumps. The air source heat pumps and hot water circulation pumps are used to heat the water contained in the water tank. When the water level is low, the water tank is replenished with water through the water replenishment system and heated again to realize the storage or supply of hot water. At present, the hot water heating regulation system has the following main shortcomings or defects: (1) The hot water tank is short of water due to water outage and other reasons, and the hot water circulation pump, air source heat pump and booster pump are still working, resulting in equipment damage; (2) Because ordinary water replenishment only uses a float valve to replenish water as needed, the water consumption during peak water consumption is high. If more cold water is replenished, the water tank temperature is too low (below 38 degrees), resulting in a low water flow temperature at the output end, affecting the use of hot water; (3) Because the peak water consumption is in the evening and morning, if water is replenished and heated at the same time when water is used, the ambient temperature is low at this time, and the air source heat pump is inefficient, wasting energy. In actual operation, the current heating system has the problem of excessive heating energy consumption and is unable to coordinate and cooperate with each unit included in the heating system to improve heating efficiency and heating operation stability.

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0034] To further illustrate the technical solution provided by the embodiment of the present application, this is described in detail below in conjunction with the accompanying drawings and specific implementation methods. Although the embodiment of the present application provides the method operation steps shown in the following embodiments or drawings, more or fewer operation steps may be included in the method based on routine or no creative labor. In the steps where there is no necessary causal relationship logically, the execution order of these steps is not limited to the execution order provided in the embodiment of the present application.

[0035] refer to Figure 1-4 As shown, the present application provides a high-efficiency and energy-saving centralized regulation system for bathing hot water, including: a water tank 11, an air source heat pump unit 21, a hot water circulation pump unit 22, a water supply pipeline 12, a water supply solenoid valve 23, a booster water pump 24, a liquid level sensor 31, a temperature sensor 32 and a controller 30.

[0036] The water tank 11 comprises a water replenishment port, an output port, a liquid inlet port and a liquid outlet port. The water replenishment port, the output port, the liquid inlet port and the liquid outlet port are respectively used to realize the delivery and output of the liquid flow.

[0037] The water replenishment port is connected to the water replenishment pipeline 12, and a water replenishment solenoid valve 23 is arranged on the water replenishment pipeline 12. The controller 30 is connected to the water replenishment solenoid valve 23. The connection, transmission or shutoff of the liquid flow on the water replenishment pipeline 12 is controlled by the operating state of the water replenishment solenoid valve 23, thereby realizing the replenishment of water in the water tank 11. When the water level in the water tank 11 is low or lower than the preset height requirement, the introduction and transmission of the liquid flow can be realized by controlling the start-up operation of the water replenishment solenoid valve 23.

[0038] The liquid outlet port is connected to the hot water circulation pump unit 22 through a pipeline, the hot water circulation pump unit 22 is connected to the air source heat pump unit 21 through a pipeline, the air source heat pump unit 21 is connected to the liquid inlet port, and the liquid in the water tank 11 is heated by the hot water circulation pump unit 22 and the air source heat pump unit 21 and then flows into the water tank 11 through the liquid inlet port.

[0039] The liquid flow circulated from the water tank 11 is first heated by the hot water circulation pump unit 22, and then heated by the air source heat pump unit 21, and then circulated from the liquid outlet port to the water tank 11, thereby completing the heating treatment of the liquid flow in the water tank 11.

[0040] Among them, the hot water circulation pump unit 22 is mainly a mechanical device that provides stable pressure and flow rate for the circulating heat carrier. It drives the impeller to rotate through the motor, so that water forms a circulation flow in the pipeline system. Specifically, the rotational energy of the motor is transmitted to the impeller, and the impeller drives the water to flow, thereby transporting hot water from the heat source (such as a water heater, boiler, etc.) to the water point, and heating the low-temperature water flow at the end before sending it out.

[0041] The air source heat pump unit 21 uses the reverse Carnot cycle principle to drive the compressor with a small amount of electric energy, so that the refrigerant absorbs low-level heat energy in the air in the evaporator and becomes a low-temperature and low-pressure gaseous refrigerant, which is then compressed into a high-temperature and high-pressure gaseous refrigerant by the compressor and enters the condenser to release heat and heat the water. After releasing the heat, the refrigerant becomes a low-temperature and high-pressure liquid, and returns to the evaporator after being throttled by the expansion valve, and continues to absorb heat from the air. This cycle repeats, continuously transferring the heat energy in the air to the water, thereby achieving the purpose of producing hot water.

[0042] The output port is connected to the bathing terminal device 13, and the booster water pump 24 is arranged on the pipeline between the output port and the bathing terminal device 13. The booster water pump 24 boosts the liquid flow output from the output port of the water tank 11 and then transports it to the bathing terminal device 13 through the corresponding pipeline to realize the effective supply of hot water for bathing.

[0043] The liquid level sensor 31 and the temperature sensor 32 are respectively arranged in the water tank 11. The liquid level sensor 31 is used to detect the height of the liquid flow currently contained in the water tank 11 and determine it as the current water level value, and the temperature sensor 32 is used to detect the temperature of the liquid flow currently contained in the water tank 11 and determine it as the current temperature value. Specifically, the temperature sensor 32 can also be arranged on the pipeline connected to the output port, so as to detect the temperature of the liquid flow contained in the water tank 11, so as to evaluate the temperature of the liquid flow delivered by the water tank 11 to the bathing terminal device 13.

[0044] The controller 30 is connected to the air source heat pump unit 21 , the hot water circulation pump unit 22 , the water replenishment solenoid valve 23 and the booster water pump 24 . The controller 30 is also connected to the liquid level sensor 31 and the temperature sensor 32 .

The water tank replenishment low temperature is 40°C.

[0049] S4: When driving the air source heat pump unit and the hot water circulation pump to continue working, if the current water temperature in the water tank reaches or exceeds the high temperature of the water tank water replenishment, the water replenishment solenoid valve is driven to start working, and the air source heat pump unit and the hot water circulation pump are driven to continue working until the water level in the water tank reaches the high water level during the high-efficiency period, otherwise repeat step S3, wherein the high temperature of the water tank water replenishment is 41°C, and the high water level during the high-efficiency period is 2.1 meters.

[0050] S5: When the water level in the water tank reaches the high water level during the high-efficiency period, the water supply solenoid valve is driven to close, and the air source heat pump unit and the hot water circulation pump are driven to continue working. When the current water temperature in the water tank reaches the water tank supply high temperature, the air source heat pump unit is driven to stop working and the hot water circulation pump is driven to stop working after a delay of 2 minutes after the hot water circulation pump stops working.

[0051] S6: If during the high-efficiency time period, the water level in the water tank drops to the low water level during the high-efficiency time period, which is 2.00 meters, repeat the above steps S2-S5.

[0052] S7: If in the non-efficient time period outside the efficient time period, if the water level in the water tank is higher than the low water level in the non-efficient time period, the water supply solenoid valve is driven to remain closed. If the current water temperature in the water tank is lower than the low working temperature of the water tank, the air source heat pump unit and the hot water circulation pump are driven to start working until the current water temperature in the water tank reaches the high working temperature of the water tank. The air source heat pump unit is driven to stop working and the hot water circulation pump is driven to stop working after a delay of 2 minutes after the hot water circulation pump stops working. Among them, the low water level in the non-efficient time period is 0.7 meters, the high working temperature of the water tank is 42°C, and the low working temperature of the water tank is 41°C.

[0053] S8: During the non-efficient time period, if the water level in the water tank is lower than the low water level during the non-efficient period, the water supply solenoid valve is driven to start working, and steps S2-S4 are repeated. When the water level in the water tank reaches the high water level during the non-efficient period, the water supply solenoid valve is driven to stop working, and the air source heat pump unit and the hot water circulation pump are driven to work. When the current water temperature in the water tank reaches the target set temperature, the air source heat pump unit is driven to stop working, and the hot water circulation pump is driven to stop working after a delay of 2 minutes after the hot water circulation pump stops working.

[0054] If the water level in the water tank reaches the high water level during the non-efficient period, the water supply solenoid valve is driven to stop working, and the air source heat pump unit and the hot water circulation pump are driven to work. When the current water temperature in the water tank reaches the target set temperature, the air source heat pump unit is driven to stop working and the hot water circulation pump is driven to stop working after a delay of 2 minutes after the hot water circulation pump stops working.

[0055] If the water level in the water tank drops to the low water level during the non-efficient period, step S8 is repeated, wherein the high water level during the non-efficient period is 0.8 meters.

[0060] Open the water supply solenoid valve again and subsequent operations: When the air source heat pump unit and the hot water circulation pump are driven to continue working, if the current water temperature in the water tank reaches or exceeds the high water supply temperature of the water tank (41°C), the water supply solenoid valve is driven to start working and continue to work until the water level in the water tank reaches the high water level during the high-efficiency period (2.1 meters); if not reached, repeat the above steps on water temperature and closing the water supply solenoid valve.

When the current water temperature in the water tank reaches the water tank replenishment high temperature, the air source heat pump unit is driven to stop working first, and then the hot water circulation pump is driven to stop working after a delay of 2 minutes after the hot water circulation pump stops working.

[0062] Water level drop processing: If the water level in the water tank drops to the low water level (2.00 meters) during the high-efficiency time period, repeat the above steps (S2-S5) from starting the heating equipment according to the water temperature to completing the high-efficiency water replenishment stage operation.
