Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration, in particular to a refrigeration medium circulating water auxiliary system. Background Art

[0002] The refrigeration process involves an evaporative cooling heat exchange system and an air cooler defrosting system. When the evaporative cooling heat exchange system is working, cold water is input and warm water is output; when the air cooler defrosting system is working, warm water is input and cold water is output.

[0003] However, the evaporative cooling heat exchange system usually uses filtered tap water to supply cold water to the evaporative cooling water tank. In spring and winter, due to the low ambient temperature, the water temperature in the evaporative cooling water tank is low (generally below 20 degrees Celsius), the evaporative cooling can operate normally and the cooling time of the refrigeration system is not affected; but in summer, due to the increase in tap water temperature and the evaporative cooling water tank being exposed to the sun, the water temperature in the evaporative cooling water tank is high (generally above 20 degrees Celsius), which will have an adverse effect on the normal operation and life of the evaporative cooling and compressor unit equipment, as well as the cooling time of the refrigeration system. Specifically, the evaporative cooling equipment will have a long evaporative cooling operation time due to the high water supply temperature, affecting the normal operation of the compressor unit, and often causing the compressor to operate at a high operating temperature and alarm shutdown protection phenomenon; at the same time, due to the high water temperature, the refrigerant (R507) that has passed through the evaporative cooling has a poor cooling effect, and the cooling effect is not good and the time is relatively long.

[0004] The air cooler defrosting system draws water from the underground defrosting pool to the air cooler coil nozzle to defrost the air cooler outlet. In order to achieve the desired defrosting effect, especially in winter, electric heating coils are usually added to the defrosting pool or on the delivery pipeline to heat the defrosting water. However, this solution will increase energy consumption and increase the difficulty of later maintenance. At the same time, the electric heating coil is very likely to short-circuit in a humid environment, posing a safety hazard of fire or electric shock. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a refrigeration medium circulating water auxiliary system with efficient energy utilization in view of the current status of the prior art.

[0006] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a refrigeration medium circulating water auxiliary system, including an air cooler, an evaporative cooler, an air cooler defrosting water pipe, an evaporative cooler hot water exchange pipe and a water reservoir, the water reservoir includes a cold water pool and a warm water pool, the air cooler defrosting water pipe includes a first water inlet pipe and a first water outlet pipe, the water inlet of the first water inlet pipe is located in the warm water pool, the water outlet of the first water inlet pipe is connected to the air cooler, the water inlet of the first water outlet pipe is connected to the air cooler, and the water outlet of the first water outlet pipe is located in the cold water pool; the evaporative cooler hot water exchange pipe includes a second water inlet pipe and a second water outlet pipe, the water inlet of the second water inlet pipe is located in the cold water pool, the water outlet of the second water inlet pipe is connected to the evaporative cooler, the water inlet of the second water outlet pipe is connected to the evaporative cooler, and the water outlet of the second water outlet pipe is located in the warm water pool.

[0007] The evaporative cooling of this system utilizes the cold water generated by defrosting to improve the effect of heat exchange; the air cooler utilizes the warm water generated by heat exchange to improve the defrosting effect.

[0008] In order to facilitate the water flow between the cold water pool and the warm water pool, a partition is arranged in the water reservoir, and the partition divides the water reservoir into the cold water pool and the warm water pool.

[0009] In order to prevent the energy of the warm water pool from being transferred to the cold water pool and thus reducing the energy utilization rate, thermal insulation layers are provided on both sides of the partition.

[0010] In order to save the amount of water used in the system, a water inlet is provided at the bottom of the partition to connect the cold water pool and the warm water pool. When water needs to be transferred from the cold water pool to the warm water pool, or from the warm water pool to the cold water pool, it is not necessary to use a pump, but only to open the water inlet.

[0011] Preferably, the evaporative cooling and water exchange pipe further includes a third water inlet pipe, which is connected to an external tap water source. In winter, the water inlet of the evaporative cooling and water exchange pipe is realized by the third water inlet pipe. Since the tap water temperature in winter is relatively low, the demand for evaporative cooling can be met without extracting cold water from a cold water pool located at a lower position, thereby reducing the energy loss of the water pump; the third water inlet pipe can also replenish water for the entire system, especially in the case of large water evaporation in summer.

[0012] In order to reasonably control the amount of water in the cold water pool and the warm water pool, the cold water pool is provided with a cold water drain pipe for draining the cold water in the cold water pool, and the warm water pool is provided with a warm water drain pipe for draining the warm water in the warm water pool.

[0013] In order to detect the changes in water volume in the cold water pool and the warm water pool, the cold water pool and the warm water pool are respectively provided with a first water level monitoring device and a second water level monitoring device; the first water inlet pipe, the second water inlet pipe and the third water inlet pipe are respectively provided with a warm water pump, a cold water pump and a tap water switch; generally speaking, the water pressure of municipal water is sufficient to directly introduce tap water into the third water pipe, and a booster pump can also be provided on the third water inlet pipe.

[0014] In order to realize automatic control of the refrigerant circulating water auxiliary system, the refrigerant circulating water auxiliary system also includes a controller, which is respectively connected to the first water level monitoring device and the second water level monitoring device, and is connected to the air cooler or the evaporative cooler, and is respectively connected to the warm water pump, the cold water pump and the tap water switch, and is respectively connected to the valves on the cold water drain pipe and the warm water drain pipe, and is connected to the switch of the water outlet.

[0015] In order to maximize the use of the heat generated by the second outlet pipe of the evaporative cooling water exchange pipe and the cold generated by the first outlet pipe of the cooling fan defrosting water pipe, at least two cooling fans are provided, and the cooling fan defrosting water pipe can be connected to each cooling fan respectively to defrost each cooling fan. Evaporative cooling needs to work every day to produce warm water, while the defrosting of the cooling fan is performed every few days. If multiple cooling fans perform defrosting on different days, the utilization rate of the heat generated by the second outlet pipe is improved, and it is also convenient for evaporative cooling to use the cold water generated by defrosting.

[0016] In order to filter out impurities generated during the defrosting process of the air cooler, a filter is provided on the first water outlet pipe.

[0017] Compared with the prior art, the utility model has the following advantages: the hot water generated by evaporative heat exchange is stored in a warm water pool, the cold water generated by the cold air fan for defrosting is stored in a cold water pool, the warm water in the warm water pool is used for defrosting the cold air fan, and the cold water in the cold water pool is used for evaporative heat exchange; through the circulation of water, higher temperature water is input into the cold air fan for defrosting, and lower temperature water is input into the evaporative cooling system; the cold air fan and the evaporative cooling each take the water of the target temperature as needed, and at the same time the defrosting efficiency and heat exchange efficiency are improved.

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] like Figures 1-2 The figure shows a preferred embodiment of the refrigerant circulating water auxiliary system of the utility model, which is a refrigerant circulating water auxiliary system, including an air cooler 1, an evaporative cooler 2 and a water reservoir. The system circulates the defrosting water of the air cooler 1 and the heat exchange water of the evaporative cooler 2, and automatically integrates the circulation of the evaporative cooler heat exchange water and the defrosting water, so as to maximize the utilization of energy and reduce energy loss.

[0022] The air cooler 1 is connected with an air cooler defrosting water pipe, which includes a first water inlet pipe 11 and a first water outlet pipe 12. After the water inlet of the first water inlet pipe 11 defrosts the air cooler 1, it flows out through the first water outlet pipe 12. The first water outlet pipe 12 is provided with a Y-type filter. It can be known that the water inlet temperature of the first water inlet pipe 11 is higher than the water outlet temperature of the first water outlet pipe 12. In this embodiment, multiple air coolers 1 are provided, and the multiple air coolers 1 are defrosted by the water flow of the first water inlet pipe 11 and the first water outlet pipe 12.

[0023] The evaporative cooling water exchange pipe is connected to the evaporative cooling water 2, and the evaporative cooling water exchange pipe includes a second water inlet pipe 21, a third water inlet pipe 23 and a second water outlet pipe 22. The water inlet of the evaporative cooling water 2 has two channels, the second water inlet pipe 21 and the third water inlet pipe 23, wherein the third water inlet pipe 23 is connected to the external tap water source through the tap water switch 30. In other embodiments, the third water inlet pipe 23 is provided with two water inlet branches connected to the external tap water source, one of which is provided with a booster pump, and the other is not provided. When the tap water pressure is insufficient, the water inlet branch provided with the booster pump is used. After the water inlet of the third water inlet pipe 23 exchanges heat with the evaporative cooling water 2, it flows out through the second water outlet pipe 22, or after the water inlet of the second water inlet pipe 21 exchanges heat with the evaporative cooling water 2, it flows out through the second water outlet pipe 22. It can be known that the water inlet temperature of the second water inlet pipe 21 and the third water inlet pipe 23 is lower than the water outlet temperature of the second water outlet pipe 22.

[0024] In addition, in order to improve the energy utilization rate of the entire system, the first water inlet 12, the first water outlet pipe 12, the second water inlet 21, the second water outlet pipe 22 and the third water inlet pipe 23 need to be insulated.

[0025] A partition 5 is arranged in the water reservoir, and the partition 5 divides the water reservoir into a cold water pool 3 and a warm water pool 4; a cold water drain pipe 31 for discharging the cold water in the cold water pool 3 is arranged on the cold water pool 3, and the cold water pool 3 is respectively provided with a first water level monitoring device 32 and a first temperature monitoring device 33; a warm water drain pipe 41 for discharging the warm water in the warm water pool 4 is arranged on the warm water pool 4, and the warm water pool 4 is respectively provided with a second water level monitoring device 42 and a second temperature monitoring device 43; both sides of the partition 5 are provided with a thermal insulation layer to prevent the temperature transfer between the cold water pool 3 and the warm water pool 4; a water inlet 51 connecting the cold water pool 3 and the warm water pool 4 is arranged at the lower part of the partition 5.

[0026] In order to realize water circulation, the water inlet of the first water inlet pipe 11 is located in the warm water pool 4, and the water outlet of the first water outlet pipe 12 is located in the cold water pool 3; the first water inlet pipe 11 is respectively provided with a warm water pump 10, and the warm water pump 10 draws the warm water in the warm water pool 4 into the air cooler 1 through the first water inlet pipe 11 for defrosting, and then flows out to the cold water pool 3 through the first water outlet pipe 12. The water inlet of the second water inlet pipe 21 is located in the cold water pool 3, and the water outlet of the second water outlet pipe 22 is located in the warm water pool 4; the second water inlet pipe 21 is provided with a cold water pump 20, and the cold water pump 20 draws the cold water in the cold water pool 3 into the evaporative cooling 2 through the second water outlet pipe 22 for heat exchange, and then flows out to the warm water pool 4 through the second water outlet pipe 22.

[0027] In order to realize automatic control of the refrigerant circulating water auxiliary system, the refrigerant circulating water auxiliary system also includes a controller 6, which is respectively connected to the first water level monitoring device 32 and the second water level monitoring device 42, the controller 6 is respectively connected to the air cooler 1 or the evaporative cooler 2, the controller 6 is respectively connected to the warm water pump 10, the cold water pump 20 and the tap water switch 30, the controller 6 is respectively connected to the valves on the cold water drain pipe 31 and the warm water drain pipe 41, and the controller 6 is connected to the switch of the water outlet 51.

[0028] The refrigeration medium circulating water auxiliary system is divided into winter working mode and summer working mode.

[0029] In the initial state of the refrigerant circulating water auxiliary system, the water inlet 51 is open, and the water amounts in the cold water pool 3 and the warm water pool 4 are the same.

[0030] The winter working mode is relatively simple, and the workflow is as follows:

[0031] Step 1, the controller 6 first turns on the tap water switch 30 and closes the water inlet 51;

[0032] Step 2, the controller 6 turns on the working button of the evaporative cooling 2 again, and the water in the third water inlet pipe 23 is heated by the evaporative cooling 2, and then flows from the second water outlet pipe 22 to the warm water pool 4 by gravity. During this process, the controller 6 opens the cold water drain pipe 31 on the cold water pool 3, and the cold water pool 3 also discharges the same volume of water as the water flowing into the second water outlet pipe 22;

[0033] Step 3, the evaporative cooling 2 needs to work multiple times in one day, and the controller 6 repeats the above steps 1 and 2 to accumulate the warm water flowing out after each operation of the evaporative cooling 2 in the warm water pool 4;

[0034] Step 4: When the air cooler 1 needs to be defrosted, the controller 6 turns on the warm water pump 10 to complete the defrosting process;

[0035] Step 5: The controller 6 opens the water inlet 51.

[0036] For example, the amount of water generated by the evaporative cooling 2 each time it works is 4 tons, and the amount of water required for defrosting the air cooler 1 is 40 tons; in this embodiment, the amount of water in the cold water pool 3 and the warm water pool 4 in the initial state is 28 tons, and the evaporative cooling 2 works 3 times a day, and the amount of warm water generated each time is 4 tons. While the warm water in the warm water pool 4 is increased, the cold water pool 3 discharges the same volume of cold water, so after the evaporative cooling 2 finishes working 3 times, the amount of water in the warm water pool 4 accumulates to 40 tons, and the amount of water in the cold water pool 3 is 16 tons; the 40 tons of warm water in the warm water pool 4 is used for defrosting the air cooler 1, and when the defrosting is completed, the water inlet 51 is opened to return to the initial state of the refrigerant circulating water auxiliary system.

[0037] When the temperature is high in summer, tap water cannot be used directly. The workflow for summer work is as follows:

[0038] Step 1, the controller 6 first turns on the cold water pump 20 on the second water inlet pipe 21 and closes the water inlet 51;

[0039] Step 2, the controller 6 turns on the working button of the evaporative cooling 2, and the water in the second water inlet pipe 21 is heated by the evaporative cooling 2, and then flows from the second water outlet pipe 22 to the warm water pool 4 by gravity;

[0040] Step 3, the evaporative cooling 2 needs to work multiple times in one day, and the controller 6 repeats the above steps 1 and 2 to accumulate the warm water flowing out after each operation of the evaporative cooling 2 in the warm water pool 4;

[0041] Step 4: When the air cooler 1 needs to be defrosted, the controller 6 turns on the warm water pump 10 to complete the defrosting process;

[0042] Step 5: The controller 6 opens the water inlet 51.

[0043] In this embodiment, the water volume of the cold water pool 3 and the warm water pool 4 in the initial state is 28 tons. The evaporative cooling 2 works three times a day, and the amount of warm water generated each time is 4 tons. Then, after the evaporative cooling 2 finishes working, the water volume in the cold water pool 3 and the warm water pool 4 are 16 tons and 40 tons respectively; the warm water pump 10 is turned on to use the 40 tons of warm water in the warm water pool 4 for defrosting the air cooler 1, and finally the water volume in the cold water pool 3 and the warm water pool 4 are 56 tons and 0 tons respectively; when the defrosting is completed, the water inlet 51 is opened to return to the initial state of the refrigerant circulating water auxiliary system.

[0044] In addition, in this embodiment, ten cold air machines 1 are provided, and the cold air machine defrosting water pipes can be connected to the ten cold air machines 1 respectively so as to defrost each cold air machine 1. According to the previous survey of the defrosting time points of the cold air machines, under normal circumstances, each cold air machine generally needs to be defrosted once every 5 days of operation. Therefore, we can automatically control the defrosting time point of each cold air machine through a time controller, defrost the first and second cold air machines 1 on the first day, defrost the third and fourth cold air machines 1 on the second day, and so on. On the sixth day, defrost the first and second cold air machines 1 again, so that each cold air machine accumulates a certain amount of frost before defrosting, and the heat generated by the evaporative cooling 2 every day can be used by the cold air machine 1, and the cold water for defrosting every day can be used by the evaporative cooling 2, so the efficiency of the entire system is higher and more energy-saving.
