Description
Technical Field
The invention relates to the technical field of new energy, in particular to an exhaust method and an exhaust system of an open type transmission and distribution system of a building ice or water cold storage air conditioner.
Background
The ice cold-storage air conditioner is characterized in that ice is made by using night valley load electric power and stored in an ice storage device, latent heat of phase change of the ice is utilized for storing cold energy, and the stored cold energy is released by melting ice in daytime, so that the power consumption load of the air conditioner and the installed capacity of an air conditioning system in the peak period of a power grid are reduced. After the ice cold storage air conditioner or the water cold storage air conditioner is installed, the air conditioner construction is usually debugged and operated.
Pipes are commonly used to deliver cold or hot water to end user air conditioning equipment where air is present when the water supply pipe is at a level above the free level of the water supply tank. Specifically, the pipeline contains gas in the water filling stage, a large amount of gas can be generated in operation, if the gas cannot be smoothly discharged, the water flow section is reduced if the gas is light, the water resistance is increased, so that the water flow pressure is unstable, the water flow is blocked if the gas is heavy, even the pipe explosion accident is caused, and the serious economic loss can be caused.
On the pipeline of the existing building transmission and distribution system, an exhaust valve is usually arranged at the high point of the pipeline, and when the air in the pipeline passes through the exhaust valve along with water flow, the air can be automatically discharged. However, for an open system with a free liquid level lower than the highest point, in actual operation, the highest point is in a negative pressure operation state, the exhaust valve is in a closed state, the exhaust effect is not achieved, and when the liquid flow rate in the pipeline is high, air is in a foam shape or a ring shape. In this way, the fluid in the delivery and distribution pipeline system always operates in a pneumatic state, thereby causing the energy efficiency of the delivery and distribution system to be reduced and even running accidents to occur.

In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
Because the exhaust method of the open type transmission and distribution system 10 of the building ice or water cold-storage air conditioner is suitable for the open type fluid transmission and distribution system with the suction section in front of the pump being higher than the free liquid level of the water tank 200, and is used for exhausting the air of the open type transmission and distribution system 10 of the building ice or water cold-storage air conditioner, the air is prevented from being contained in the water flow in the pipeline of the open type transmission and distribution system 10 of the building ice or water cold-storage air conditioner, and the air enters the user equipment 100 along with the water flow, so that the user equipment 100 is damaged. Alternatively, the gas may follow the flow of the water stream causing damage to the pipeline. The structure of the open air conditioning delivery system 10 for ice or water storage in a building will be described first.
Referring to fig. 2, arrows in fig. 2 indicate circulation routes of water flow. In some embodiments, the building ice or water storage air conditioning open delivery system 10 includes: the water supply system includes a user equipment 100, a water tank 200, a water return pipe 300, a water supply pipe 400, a water replenishment pipe 500, an exhaust pipe 600, and a branch pipe 700. The user equipment 100 may be a cold or hot equipment such as a plate heat exchanger, fan coil, etc. Both ends of the water supply pipe 400 are respectively communicated with the user equipment 100 and the sump 200, and both ends of the water return pipe 300 are respectively communicated with the user equipment 100 and the sump 200 to form a circulation waterway, and the water supply pipe 400 is further provided with a circulation pump 410, the circulation pump 410 being used for delivering fluid to the user equipment 100. That is, when the user equipment 100 is a hot device, the water in the sump 200 is generally cold water, the circulating water pump 410 flows the cold water to the user equipment 100 through the water supply pipe 400, the user equipment 100 exchanges heat with the cold water, and the hot water flows back to the sump 200 through the water return pipe 300.
It should be noted that, since the open type transmission and distribution system 10 for ice or chilled water storage air conditioner of the present application can save water resources, fluid can be delivered back to the pool 200 through the water return pipe 300. In other embodiments, the return line 300 may connect additional tanks 200, such as two tanks 200, one tank 200 communicating with the water supply line 400 and the other tank 200 communicating with the return line 300.
The water replenishment pump 510 is installed at the initial end of the water replenishment pipe 500, and the initial end of the water replenishment pipe 500 and the water replenishment pump 510 are located in the water tank 200 together, and the end of the water replenishment pipe 500 is communicated with the water supply pipe 400. The water supplementing pump 510 may be a submersible water supplementing pump, which has low cost. In the method for exhausting the open type transmission and distribution system 10 of the ice or chilled water storage air conditioner of the building, which is described below, the submersible water supplementing pump 510 can save a certain cost.
The vacuum machine 610 is installed at the end of the exhaust pipe 600, and the end of the exhaust pipe 600 is located above the sump 200, and the initial end of the exhaust pipe 600 is communicated with the water supply pipe 400. The vacuum machine 610 is used for actively pumping the accumulated air in the water supply pipe 400, and when the air exhaust pipe 600 is opened, the air and water flow can be discharged, and the water flow can flow into the water tank 200 to be reused to avoid waste. An exhaust valve 710 may be installed on the exhaust pipe 600, and fluid may be prevented from entering the exhaust pipe 600 and the branch pipe 700 when the exhaust valve 710 is closed.
The initial end of the branch pipe 700 is connected to the exhaust pipe 600, the end of the branch pipe 700 is located above the sump 200, and the end of the branch pipe 700 is installed with an exhaust valve 710. The vent valve 710 may be opened to facilitate fluid flow from the end of the branch conduit 700.
Further, referring to fig. 1, the exhaust method of the open type transmission and distribution system 10 of the ice or water cold storage air conditioner for a building in the above embodiment includes the steps of:
s100, closing the circulating water pump 410, and opening the water supplementing pump 510 and the exhaust valve 710 to enable fluid to flow out from the tail end of the branch pipeline 700;
and 200, closing the water supplementing pump 510 and the exhaust valve 710, and opening the vacuum machine 610 to enable the fluid to flow out from the tail end of the exhaust pipeline 600.
Specifically, referring to fig. 3, the arrows in fig. 3 indicate the route of the fluid flow in step S100. When the building ice or water cold storage air conditioner open type transmission and distribution system 10 is used for exhausting, normal-temperature municipal tap water is not required to be introduced, so that the cold or heat loss and the waste of municipal tap water resources caused by introducing normal-temperature municipal tap water in the traditional exhaust method are avoided. After the circulation water pump 410 is turned off, fluid may be prevented from entering the user equipment 100. It is also conceivable that the fluid will be stationary after the circulating water pump 410 is turned off, so that the gas automatically gathers to the top of the pipe, and thus the concentrated discharge can be facilitated. After the water replenishment pump 510 is turned on, the water replenishment pump 510 delivers the fluid in the tank 200 to the end of the branch pipe 700 where the vent valve 710 is opened, allowing the fluid to flow out of the end of the branch pipe 700, and in particular back to the tank 200. As such, a majority of the gas and water flow within the pipes of the building ice or water cooled air conditioning open system 10 will flow out the ends of the branch pipes 700. In addition, the discharged water flow can be collected in the pool 200 to avoid waste, and energy can be saved. And, when the user equipment 100 is replenished with water, the water in the water tank 200 is used for replenishing, so that the water tank 200 is replenished with water in a manner opposite to the water replenishing manner of municipal tap water, and the cooling capacity or heat loss caused by temperature difference can be effectively avoided. The water tank can be ice water, the temperature is about zero degree, the temperature of municipal tap water is about twenty degrees, the temperature difference between the municipal tap water and the fluid in the water tank 200 is large, extra energy consumption is needed for reducing the temperature of the municipal tap water to about zero degree, and because the volume of the water tank 200 is limited, the extra and supplementary municipal tap water flows out from the overflow port 210 of the water tank 200, so that water resource waste is caused.
Further, referring to fig. 4, the arrow in fig. 4 indicates the route of the fluid flow in step S200. After the water make-up pump 510 and the exhaust valve 710 are closed, a small portion of the air and water flow in the pipes of the ice or chilled water storage air conditioning open type transmission and distribution system 10 can be pumped to the end of the exhaust pipe 600 and exhausted by opening the vacuum machine 610. Therefore, the gas in the pipeline of the building ice or water cold storage air conditioner open type transmission and distribution system 10 is further discharged, and the exhaust method of the building ice or water cold storage air conditioner open type transmission and distribution system 10 can effectively solve the problem that the exhaust valve 710 cannot thoroughly discharge accumulated gas.
Specifically, the open type transmission and distribution system 10 of the building ice or chilled water storage air conditioner can supplement the liquid level in the water supply pipeline 400 through the fluid in the water tank, avoid cold or heat loss, and discharge the gas in the pipeline while supplementing water. When the water is supplemented in the exhaust mode in the prior art, not only is the cold and heat wasted, but also a large amount of water is wasted, and the energy is not saved.
It should be noted that, the gas in the pipeline of the open type transmission and distribution system 10 for building ice or chilled water storage air conditioner may specifically refer to the gas in the water supply pipeline 400, after the circulating water pump 410 is turned off, the gas and water flow in the water supply pipeline 400 may be pushed to the end of the branch pipeline 700 by the water supplementing pump 510 to flow out, at this time, only one opening is formed at the end of the branch pipeline 700 in the open type transmission and distribution system 10 for building ice or chilled water storage air conditioner, so that the fluid must flow out therefrom. In addition, the gas in the pipes of the open type transmission and distribution system 10 of the ice or chilled water storage air conditioner can be the gas in other pipes, such as the gas in the branch pipe 700 and the exhaust pipe 600.
Fluid refers to a mixture of gas and water streams or a separate water stream. When the fluid in step S100 flows out of the end of the branch conduit 700, typically a mixture of gas and water flows, only the water flow may flow out without gas after a period of time has elapsed. The fluid in step S200 may initially be a small flow of gas and water, and after a period of time, may only flow of water and no gas.
In order to ensure that the exhaust method of the open type transmission and distribution system 10 of the ice or water cold storage air conditioner of the building has good effect on the exhaust of the gas in the pipeline, some specific embodiments exist. In some embodiments, after the circulating water pump 410 is turned off, the method for exhausting the open type transmission and distribution system 10 of the ice or water cold storage air conditioner of the building further comprises the steps of: when the fluid in the pipeline of the open type transmission and distribution system 10 of the ice or water cold storage air conditioner of the building still flows, the water supplementing pump 510 and the exhaust valve 710 are opened. In particular, when the fluid is flowing still, the gas below the water flow can float still above the water flow, thereby separating the water flow from the gas (the middle part of the water flow also has gas in the flowing process). Further, the water in the sump 200 is pushed to the end of the branch pipe 700 by the water replenishment pump 510, and the gas is discharged together.
Further, in some embodiments, after the water make-up pump 510 and the air outlet valve 710 are closed, the air outlet method of the open type transmission and distribution system 10 of the ice or chilled water storage air conditioner further comprises the steps of: the vacuum 610 is turned on again when the fluid in the pipes of the ice or chilled water storage air conditioning open system 10 is flowing still. Specifically, when the flow of water stops, the gas and the flow of water are separated, so that the extraction of the gas and the flow of water by the vacuum machine 610 is more effective. Thus, the exhaust method of the open type transmission and distribution system 10 of the building ice or water cold storage air conditioner can effectively solve the problem that the exhaust valve 710 can not thoroughly exhaust accumulated air.
Further, after the vacuum 610 has drawn fluid for a period of time, it may be determined whether gas is still present in the water stream by detecting the pressure within the conduits of the building ice or chilled water storage air conditioning open delivery system 10. Thus, in some embodiments, the method of exhausting an open air delivery system 10 for a building ice or water chiller air conditioner further comprises the steps of: when fluid is continuously discharged from the end of the exhaust pipe 600, the vacuum machine 610 is turned off, and then the pressure in the pipe of the open type transmission and distribution system 10 of the ice or chilled water storage air conditioner is detected.
Further, if in the above embodiment, it is detected that there is gas in the pipeline of the open type transmission and distribution system 10 of the ice or chilled water storage air conditioner, it is further necessary to use the vacuum machine 610 to pump out the gas. Therefore, please refer to fig. 4. In some embodiments, when the detected pressure is unstable, the make-up pump 510 and the vent valve 710 are kept closed, the vacuum 610 is turned on, fluid is allowed to flow out of the end of the vent line 600, and then the pressure in the lines of the ice or water storage air conditioning open type delivery system 10 is detected.
In addition to the above-mentioned method for exhausting the open type transmission and distribution system 10 of the ice or water cold-storage air conditioner for building, another method for exhausting the open type transmission and distribution system 10 of the ice or water cold-storage air conditioner for building is also provided. In the method for exhausting the open type transmission and distribution system 10 of the ice or water cold-storage air conditioner for a building, please refer to fig. 6, wherein arrows in fig. 6 indicate the flow path of the fluid.
