Description

Technical Field

[0001] The present invention belongs to the technical field of cooling, and specifically relates to a direct water-cooling storage cooling system. Background Art

[0002] When the central air conditioner is cooling, it consumes a large amount of electricity. At the same time, due to the implementation of peak-valley electricity prices by the state, especially during peak electricity consumption periods, the electricity consumption is concentrated and the electricity price is high. At this time, the electricity price of the central air conditioner is much higher than that in the flat electricity stage, greatly increasing the electricity consumption cost. The water-cooling storage air conditioner is a user management technology that has a significant effect on shifting the peak and filling the valley of the power grid load. This technology uses the surplus electricity at night to start the refrigeration unit for refrigeration, stores the cold energy in the form of low-temperature cold water, and releases the stored cold energy during the peak electricity consumption period during the day to meet the needs of air conditioner users, thereby avoiding or reducing the use of electricity during peak periods, alleviating the peak-valley difference contradiction of the power grid load, improving the operation efficiency of power plants, and achieving energy conservation and emission reduction benefits.

[0003] In the prior art, the operation of the water-cooling storage cooling system is too cumbersome and not concise enough. The system setting and system operation require a large amount of manpower and material resources, and the system is prone to confusion, resulting in the situation of alternating cooling and cold release. Therefore, the present invention provides a direct water-cooling storage cooling system. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to overcome the deficiencies in the prior art and provide a direct water-cooling storage cooling system.

[0005] In order to make up for the deficiencies in the prior art and solve the problems that the operation of the water-cooling storage cooling system is too cumbersome and not concise enough, the system setting and system operation require a large amount of manpower and material resources, and the system is prone to confusion, resulting in the situation of alternating cooling and cold release, the present invention proposes a direct water-cooling storage cooling system.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: A direct water-cooled energy storage cooling system of the present invention includes a cooling tower, a cooling pump, a cooling main unit, a chilled water pump, a water distributor, a water collector, a central air conditioner, a storage and discharge pump, and a check valve; the cooling tower is connected to the cooling main unit through a water pipe; the cooling main unit is connected to the water distributor through a water pipe; the water distributor is connected to the central air conditioner through a water pipe; the central air conditioner is connected to the water collector through a water pipe; the water collector is connected to the chilled water pump through a water pipe; the chilled water pump is connected to the cooling main unit through a water pipe; the cooling main unit is connected to the cooling pump through a water pipe; the cooling pump is connected to the cooling tower through a water pipe; the cooling main unit is connected to a cold storage tank through a water pipe; the water collector is interconnected with the cold storage tank through a water pipe; the cold storage tank is interconnected with the storage and discharge pump through a water pipe; the storage and discharge pump is connected to the water distributor through a water pipe; the storage and discharge pump is connected to the cooling main unit through a water pipe; in the prior art, a large amount of electricity is consumed when the central air conditioner is refrigerating. At the same time, due to the implementation of peak-valley electricity prices by the state, especially during peak electricity consumption periods, the electricity consumption is concentrated and the electricity price is high. At this time, the electricity price for the central air conditioner is much higher than that during the flat electricity stage, greatly increasing the electricity consumption cost; the system of the present invention includes two modes: flat price mode: during the period of flat electricity price, the cooling tower, the cooling pump, the cooling main unit, and the chilled water pump are started at this time, so that the refrigerated water flow enters the water distributor to supply cooling to the central air conditioner. The water flow of the central air conditioner forms a cooling water circulation through the water collector, the chilled water pump, the cooling main unit, the cooling pump, and the cooling pump. At the same time, when the cooling main unit is working, it will also refrigerate and enter the cold storage tank through a water pipe to perform cold storage treatment on the cold storage tank. The hot water in the cold storage tank will enter the cooling main unit through the storage and discharge pump; peak mode: during the peak electricity price period, the cooling tower, the cooling pump, the cooling main unit, and the chilled water pump are all in the closed state at this time. The storage and discharge pump is started at this time, and the cold water flow in the cold storage tank is used by the storage and discharge pump to flow through the water distributor to enter the central air conditioner for refrigeration treatment. At the same time, the water flow of the water collector will enter the cold storage tank through a water pipe to form a water circulation. The cooling main unit and the like are used to store cold in the cold storage tank during the valley electricity price period, and the storage and discharge pump is operated during the peak and flat electricity price periods to transfer the cold quantity of the cold storage tank to the central air conditioner, shifting the peak and filling the valley to save electricity bills, balancing the electricity load and reducing the installed capacity of the transformer. The operation is simple and convenient, the system setting and system operation are concise, the situation of system load faults is reduced. At the same time, by using the siphon principle of the storage and discharge pump, the water pipe head can be effectively saved.

[0007] Preferably, valves A and D are provided on the water pipes after the cold storage tank and the cold storage and release pump, and valves A and D are arranged in parallel; valves F, G and E are provided on the water pipes between the cold storage tank and the cooling main unit, and valves F and G are arranged in parallel; a check valve and valve C are provided on the water pipe between the cold storage and release pump and the water distributor; valve B is provided on the water pipe between the cold storage and release pump and the cooling main unit, and valve B and valve C are arranged in parallel; a proportional integral valve is provided on the water pipe between the water collector and the cold storage tank; the proportional integral valve and valve E are arranged in parallel; during operation, in the flat-rate mode, at this time, valves G, E, A, the check valve and valve B are in the open state, and valves D, F, C and the proportional integral valve are in the closed state. At this time, the cooling main unit is started to perform cold storage treatment on the cold storage tank; in the peak mode, at this time, valves G, E, A and valve B are in the closed state, and valves D, F, C and the proportional integral valve are in the open state. The cold energy of the cold storage tank is used for cold consumption of the central air conditioner. At the same time, the proportional integral valve is used to further facilitate the adjustment of the cold consumption volume.

[0008] Preferably, valves A, B, C, D, E, F, G and the proportional integral valve are all electrically operated; during operation, the flow rate of the flow can be accurately positioned by using the setting of the electric valves.

[0009] Preferably, the cold storage tank includes a tank body and a water distribution member; a pair of water distribution members are provided at the top and bottom of the tank body, and a pair of water distribution members are symmetrically arranged; the water distribution member includes an annular pipe; a first water pipe is fixedly connected inside the cold storage tank, and the first water pipe is L-shaped; a group of first communication pipes are fixedly connected to the outer side wall of the top end of the first water pipe; a group of annular pipes are fixedly connected to a group of the first communication pipes, and the radii of a group of the annular pipes increase in sequence from inside to outside; the first water pipe, the first communication pipes and the annular pipes are interconnected; a group of first spray heads are provided on the annular pipe, and the first spray heads are horizontally arranged; during operation, when the water flow passes through the first water pipe, and then passes through a group of first connection pipes and a group of annular pipes for water inlet. At the same time, because the first spray heads are horizontally arranged, the water flow cannot directly impact downward or upward at this time. By using horizontal spraying, the impact force of the water flow is reduced, and thus the disturbance of the water flow can be slowed down, ensuring the state of the thermocline.

[0010] Preferably, a group of first annular plates are fixedly connected to a group of the first communication pipes; a group of the first annular plates and a group of the annular pipes are arranged in an alternating manner; during operation, by using the alternating arrangement of the first annular plates and a group of the annular pipes, the water flow impact force of the first spray heads will directly impact on the first annular plates at this time, and then flow along the first annular plates, which can prevent the water sprayed by the first spray heads from hitting the annular pipes, resulting in the water flow being too scattered and affecting the uniformity.

[0011] Preferably, a pair of first flow equalizing plates are fixedly connected to the inner wall of the tank, and the pair of first flow equalizing plates are symmetrically arranged; a group of first through holes are formed in the first flow equalizing plates; the cross section of the first flow equalizing plates is an inverted cone; during operation, after the water flows down along the first annular plate, it will flow onto the first flow equalizing plates. Due to the conical setting of the first flow equalizing plates, the water will slowly flow on the inclined surfaces of the first flow equalizing plates, thereby avoiding water discharge only below the first uniform plate. By using the first flow equalizing plates, water can be discharged from the entire interface of the tank, thus ensuring uniformity.

[0012] Preferably, second annular plates are fixedly connected to the ends of a group of the first annular plates close to the flow equalizing plates; the distances from the ends of the group of second annular plates close to the first flow equalizing plates to the conical inclined surfaces of the first flow equalizing plates are the same; during operation, due to the conical inclined surface problem of the first flow equalizing plates, in order to ensure that the water flow of the first annular plate at the top of the tank can fully condense and flow down onto the first flow equalizing plates, second annular plates are fixedly connected to the bottom ends of the first annular plates, and the distances from the bottom ends of the group of second annular plates to the conical inclined surfaces of the first flow equalizing plates are the same.

[0013] Preferably, the cross section of the second annular plate is a right trapezoid; the right trapezoid inclined surface of the second annular plate is located on the outer ring wall of the second annular plate; during operation, the cross section of the second annular plate is a right trapezoid. Since the water flow impact force inside the annular pipe is large, a right trapezoid inclined surface is provided on the outer side wall of the second annular plate, which can increase the downward flow time of the water flow by using the fact that the length of the inclined surface is longer than that of the straight surface, ensuring that the water flows on the first annular plate can contact the first flow equalizing plates almost simultaneously.

[0014] Preferably, arc-shaped grooves are formed on both the inner ring wall and the outer ring wall of the first annular plate; during operation, with the arc-shaped grooves provided, the impact force of the water flow can be further reduced by using the annular grooves, ensuring the downward water flow speed.

[0015] Preferably, first drainage grooves are formed on the inner ring wall of the second annular plate, and the first drainage grooves communicate with the arc-shaped grooves on the inner ring wall of the first annular plate; second drainage grooves are formed on the inclined surface of the outer side wall of the second annular plate, and the second drainage grooves communicate with the arc-shaped grooves on the outer side wall of the first annular plate; during operation, with a group of first drainage grooves and second drainage grooves provided, it is convenient for the water flow in the arc-shaped grooves to be evenly discharged from the first annular plate and the second annular plate, ensuring the uniform discharge effect.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. For the water-cooled energy storage direct cooling system of the present invention, by operating the cooling host during the valley electricity price period to store cold in the energy storage tank, and operating the discharge pump during the peak and flat electricity price periods to transfer the cold energy of the energy storage tank to the central air conditioner, peak shifting and valley filling can save electricity costs, balance the electricity load, and reduce the installed capacity of the transformer, etc.

[0018] 2. The water storage and cold direct supply system described in the present invention passes water through the first water pipe, and then through a set of first connecting pipes and a set of annular pipes for water inlet. At the same time, since the first nozzle is horizontally arranged, the water flow cannot directly impact downward or upward at this time. By using horizontal spraying, the impact force of the water flow is reduced, and thus the disturbance of the water flow can be slowed down, ensuring the state of the thermocline.

The system of the present invention comprises two modes: parity mode: during the period of electricity parity, the cooling tower 1, the cooling pump 11, the cooling host 12 and the freezing pump 13 are started, and the refrigerated water flows into the water distributor 14 to cool the central air conditioner 16. The water flow of the central air conditioner 16 passes through the water collector 15 and passes through the freezing pump 13, the cooling host 12, the cooling pump 11 and the cooling pump 11 to form a cooling water circulation.

The hot water in the cold storage tank 3 will enter the cooling host 12 through the storage pump 17; peak mode: during the use During peak electricity prices, the cooling tower 1, cooling pump 11, cooling host 12 and freezing pump 13 are all in closed state. At this time, the storage and discharge pump 17 is started, and the cold water flow in the cold storage tank 3 is flowed through the water distributor 14 into the central air conditioner 16 for refrigeration treatment by the storage and discharge pump 17. At the same time, the water flow from the water collector 15 will enter the cold storage tank 3 through the water pipe, forming a water cycle. The cooling host 12 is operated during the off-peak electricity price period to store cold in the cold storage tank 3. The storage and discharge pump 17 is operated during the peak and off-peak electricity price period to transfer the cold energy of the cold storage tank 3 to the central air conditioner 16, thereby shifting the peak to fill the valley to save electricity bills, balancing the power load and reducing the installed capacity of the transformer.

[0030] A valve A21 and a valve D24 are provided on the water pipe after the cold storage tank 3 and the storage and release pump 17, and the valve A21 and the valve D24 are arranged in parallel; a valve F26, a valve G27 and a valve E25 are provided on the water pipe between the cold storage tank 3 and the cooling main unit 12, and the valve F26 and the valve G27 are arranged in parallel; a check valve 2 and a valve C23 are provided on the water pipe between the storage and release pump 17 and the water distributor 14; a valve B22 is provided on the water pipe between the storage and release pump 17 and the cooling main unit 12, and the valve B22 and the valve C23 are arranged in parallel; a proportional integral valve 28 is provided on the water pipe between the water collector 15 and the cold storage tank 3; the proportional integral valve 28 and the valve E25 are arranged in parallel; during operation, in the flat-rate mode, at this time, the valve G27, the valve E25, the valve A21, the check valve 2 and the valve B22 are in the open state, and the valve D24, the valve F26, the valve C23 and the proportional integral valve 28 are in the closed state. At this time, the cooling main unit 12 is started to perform cold storage treatment on the cold storage tank 3; in the peak mode, at this time, the valve G27, the valve E25, the valve A21 and the valve B22 are in the closed state, and the valve D24, the valve F26, the valve C23 and the proportional integral valve 28 are in the open state. The cold storage tank 3 is used to cool the central air conditioner 16, and at the same time, the proportional integral valve 28 is used to further facilitate the adjustment of the cooling capacity.

[0031] The valve A21, the valve B22, the valve C23, the valve D24, the valve E25, the valve F26, the valve G27 and the proportional integral valve 28 are all electrically operated; during operation, the flow rate of the flow can be accurately positioned by using the setting of the electric valve.

By using horizontal spraying, the impact force of the water flow is reduced, and thus the disturbance of the water flow can be slowed down to ensure the state of the thermocline.

[0033] A group of first annular plates 36 are fixedly connected to a group of the first connecting pipes 33; a group of the first annular plates 36 and a group of annular pipes 32 are staggered; during operation, by using the staggered distribution of the first annular plates 36 and a group of annular pipes 32, at this time, the water flow impact force of the first nozzle 35 will directly impact on the first annular plates 36, and then flow along the first annular plates 36, which can avoid the water sprayed by the first nozzle 35 from hitting the annular pipes 32, resulting in the water flow being too scattered and affecting the uniformity.

[0034] A pair of first flow equalizing plates 37 are fixedly connected to the inner wall of the tank body 31, and the pair of first flow equalizing plates 37 are symmetrically arranged; a group of first through holes 38 are formed in the first flow equalizing plates 37; the cross-section of the first flow equalizing plates 37 is an inverted cone; during operation, after the water flow flows down along the first annular plates 36, it will flow onto the first flow equalizing plates 37. Due to the conical setting of the first flow equalizing plates 37, the water flow will slowly flow on the inclined surfaces of the first flow equalizing plates 37, thereby avoiding water discharge only from the lower part of the first uniform plate. By using the setting of the first flow equalizing plates 37, the water can flow out evenly on the interface of the tank body 31, thereby ensuring the uniformity.

[0035] A group of second annular plates 39 are fixedly connected to the ends of a group of the first annular plates 36 close to the flow equalizing plates; the distances from the ends of a group of the second annular plates 39 close to the first flow equalizing plates 37 to the conical inclined surfaces of the first flow equalizing plates 37 are the same; during operation, due to the conical inclined surface problem of the first flow equalizing plates 37, in order to ensure that the water flow of the first annular plates 36 at the top of the tank body 31 can fully condense and flow down onto the first flow equalizing plates 37, second annular plates 39 are fixedly connected to the bottom ends of the first annular plates 36, and the distances from the bottom ends of a group of the second annular plates 39 to the conical inclined surfaces of the first flow equalizing plates 37 are the same.

[0036] The cross-section of the second annular plate 39 is a right trapezoid; the right trapezoid inclined surface of the second annular plate 39 is located on the outer ring wall of the second annular plate 39; during operation, it is provided that the cross-section of the second annular plate 39 is a right trapezoid. Since the water flow impact force inside the annular pipe 32 is large, a right trapezoid inclined surface is provided on the outer side wall of the second annular plate 39, which can increase the downward flow time of the water flow by using the fact that the length of the inclined surface is longer than that of the straight surface, and ensure that the water flows on the first annular plates 36 that discharge water simultaneously can contact the first flow equalizing plates 37 almost simultaneously.

[0039] Working principle: When the central air conditioner 16 is cooling, it consumes a large amount of electricity. At the same time, due to the implementation of peak-valley electricity prices by the state, especially during peak electricity consumption periods, the electricity consumption is concentrated and the electricity price is high. At this time, the electricity price of the central air conditioner 16 is much higher than that in the flat electricity stage, greatly increasing the electricity consumption cost. The system of the present invention includes two modes: flat price mode: during the flat electricity price period, the cooling tower 1, cooling pump 11, cooling host 12 and chilled water pump 13 are started at this time, and the cooling water flow is allowed to enter the water distributor 14 to supply cooling to the central air conditioner 16. The water flow of the central air conditioner 16 passes through the water collector 15 and forms a cooling water cycle through the chilled water pump 13, cooling host 12, cooling pump 11 and cooling pump 11. At the same time, when the cooling host 12 is working, it will simultaneously cool and enter the cold storage tank 3 through the water pipe to perform cold storage treatment on the cold storage tank 3. The hot water in the cold storage tank 3 will enter the cooling host 12 through the storage and release pump 17; Peak mode: During the peak electricity price period, the cooling tower 1, cooling pump 11, cooling host 12 and chilled water pump 13 are all in the closed state at this time. The storage and release pump 17 is started at this time, and the cold water flow in the cold storage tank 3 is used by the storage and release pump 17 to flow through the water distributor 14 to enter the central air conditioner 16 for refrigeration treatment. At the same time, the water flow of the water collector 15 will enter the cold storage tank 3 through the water pipe to form a water cycle. Then, during the valley electricity price period, the cooling host 12 and the like are operated to store cold in the cold storage tank 3. During the peak and flat electricity price periods, the storage and release pump 17 is operated to transfer the cold energy of the cold storage tank 3 to the central air conditioner 16, shifting the peak and filling the valley to save electricity bills and balancing the electricity load to reduce the installed capacity of the transformer, etc.; During the flat price mode process, at this time, the valve G27, valve E25, valve A21, check valve 2 and valve B22 are in the open state, and the valve D24, valve F26, valve C23 and proportional integral valve 28 are in the closed state. At this time, the cooling host 12 is started to perform cold storage treatment on the cold storage tank 3; In the peak mode, at this time, the valve G27, valve E25, valve A21 and valve B22 are in the closed state, and the valve D24, valve F26, valve C23 and proportional integral valve 28 are in the open state. The cold energy of the cold storage tank 3 is used to perform cold treatment on the central air conditioner 16. At the same time, the proportional integral valve 28 is used to further facilitate the adjustment of the cold consumption; When the water flow passes through the first water pipe 34 and then through a group of first connecting pipes and a group of annular pipes 32 for water inlet. At the same time, since the first nozzle 35 is horizontally arranged, the water flow cannot directly impact downward or upward at this time. Using horizontal spraying, the impact force of the water flow is reduced, and thus the disturbance of the water flow can be slowed down to ensure the state of the thermocline; Using the staggered distribution of the first annular plate 36 and a group of annular pipes 32, at this time, the impact force of the water flow of the first nozzle 35 will directly impact on the first annular plate 36 and then flow along the first annular plate 36, which can prevent the water flow sprayed by the first nozzle 35 from hitting the annular pipe 32, resulting in the water flow being too scattered and affecting the uniformity;After the water flow flows down along the first annular plate 36, it will flow onto the first flow equalizing plate 37. Since the first flow equalizing plate 37 is conically arranged, the water flow will slowly flow on the inclined surface of the first flow equalizing plate 37, thereby avoiding water discharge only from the lower part of the first uniform plate. By using the setting of the first flow equalizing plate 37, the interface of the tank body 31 can be made to receive water discharge, thus ensuring uniformity; due to the conical inclined surface of the first flow equalizing plate 37, in order to ensure that the water flow on the first annular plate 36 at the top of the tank body 31 can fully coagulate and flow down onto the first flow equalizing plate 37, a second annular plate 39 is fixedly connected to the bottom end of the first annular plate 36, and the distance from the bottom end of a group of second annular plates 39 to the conical inclined surface of the first flow equalizing plate 37 is the same; the cross-section of the second annular plate 39 is a right trapezoid. Since the water flow impact force inside the inner ring of the annular pipe 32 is large, a right trapezoidal inclined surface is provided on the outer side wall of the second annular plate 39, which can increase the downward flow time of the water flow by using the fact that the length of the inclined surface is longer than that of the straight surface, and ensure that the water flow on the first annular plate 36 that discharges water simultaneously can contact the first flow equalizing plate 37 almost simultaneously.;

It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
