Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioner condensate water recovery, and particularly relates to a condensate water collecting tank, a temperature control method and a condensate water recovery system. BACKGROUND

[0002] With the continuous growth of the national economy and the continuous development of urbanization, large central air conditioning systems are becoming more and more popular. In summer, when the central air conditioning system is running in the cooling mode, the low-temperature refrigerant enters the indoor evaporator, reducing the temperature of the evaporator surface, and the temperature of the evaporator surface is usually lower than the dew point temperature of the air. When the air flows through the evaporator surface, the air temperature will be reduced, and when the air temperature is reduced to below the dew point temperature, the water vapor in the air will condense to form condensate water. Condensate water is continuously generated with the operation of the central air conditioning system. At present, the condensate water generated by the central air conditioning system is directly discharged, and rarely reused, not only causing a large amount of water resources to be wasted, but also the energy contained in the condensate water not being fully utilized.

[0003] At present, a condensate water recovery system that uses a condensate water collecting tank to collect condensate water and uses the condensate water collected by the condensate water collecting tank as the refrigerant of a radiant cooling system has appeared, so as to save water resources and fully utilize the energy contained in the condensate water. However, the condensate water collecting tank in this condensate water recovery system can only collect condensate water and cannot mix the condensate water uniformly, resulting in the temperature of the condensate water output by the condensate water collecting tank being non-uniform, thereby affecting the cooling effect of the radiant cooling system.

[0004] Therefore, it is necessary to design a condensate water collecting tank, a temperature control method and a condensate water recovery system, so that the temperature of the condensate water output by the condensate water collecting tank is uniform, thereby improving the cooling effect of the radiant cooling system. SUMMARY

[0010] Optionally, it further comprises a second condensate water inlet pipe communicating with the top of the tank body, and the second condensate water inlet pipe is located directly above the third partition plate and the third baffle.

[0028] Embodiment one,

[0029] Reference Figure 1 , Figure 1is a structural schematic view of the condensate water collecting tank 100 in the first embodiment of the present application. The present embodiment provides a condensate water collecting tank 100, which comprises a tank body 110, a first partition plate 120 and a second partition plate 130 extending from the bottom to the top of the tank body 110, a third partition plate 140 extending from the top to the bottom of the tank body 110, a first condensate water inlet pipe 150 and a tap water inlet pipe 160 communicating with the top of the tank body 110, and a condensate water outlet pipe 170 communicating with the bottom of the tank body 110. The first partition plate 120 and the second partition plate 130 divide the tank body 110 into a first water tank 180, a second water tank 190 and a third water tank 200 arranged side by side. The first partition plate 120 is adjacent to the first water tank 180 and the second water tank 190. The free end of the third partition plate 140 extends into the second water tank 190. The height of the first partition plate 120 is higher than that of the second partition plate 130. The first condensate water inlet pipe 150 is located directly above the first water tank 180. The tap water inlet pipe 160 is located directly above the second water tank 190. The condensate water outlet pipe 170 communicates with the third water tank 200.

[0030] In the present embodiment, the first partition plate 120 and the second partition plate 130 divide the tank body 110 into the first water tank 180, the second water tank 190 and the third water tank 200 arranged side by side. The first partition plate 120 is adjacent to the first water tank 180 and the second water tank 190. The first condensate water inlet pipe 150 is located directly above the first water tank 180. The tap water inlet pipe 160 is located directly above the second water tank 190. The condensate water outlet pipe 170 communicates with the third water tank 200. The height of the first partition plate 120 is higher than that of the second partition plate 130. Therefore, the condensate water in the first condensate water inlet pipe 150 can enter the first water tank 180. After the water level in the first water tank 180 is flush with the first partition plate 120, the condensate water can overflow from the first water tank 180 to the second water tank 190. The condensate water in the second water tank 190 can be mixed with the tap water in the tap water inlet pipe 160 to obtain mixed water after being tempered. The mixed water flows into the third water tank 200 through the gap between the second partition plate 130 and the third partition plate 140. The mixed water in the third water tank 200 is discharged from the condensate water outlet pipe 170.

[0031] Since the water entering the second water tank 190 is overflowed from the first water tank 180 to the second water tank 190, and the free end of the third partition plate 140 extends into the second water tank 190, the water in the second water tank 190 can flow from the bottom into the third water tank 200 through the gap between the second partition plate 130 and the third partition plate 140, so that the path of the condensed water and the tap water is lengthened, and the condensed water and the tap water are mixed sufficiently, so that the temperature of the mixed water discharged from the condensed water drain pipe 170 is uniform, and the cooling effect of the radiant cooling system is improved.

[0032] With reference to Figure 1 , the condensed water collecting tank 100 further comprises a water baffle 210 connecting the first partition plate 120 and the third partition plate 140, and a plurality of through holes 211 are formed in the water baffle 210, so that the condensed water and the tap water flow through the water baffle 210 from above to below. Since the water baffle 210 with a plurality of through holes 211 is arranged, the speed of the condensed water and the tap water passing through the water baffle 210 is slowed down, so that the condensed water and the tap water can be mixed sufficiently before passing through the water baffle 210, so that the temperature of the mixed water discharged from the condensed water drain pipe 170 is uniform, and the cooling effect of the radiant cooling system is improved.

[0033] With reference to Figure 1 , the water baffle 210 comprises a first baffle 212, a second baffle 213, and a third baffle 214 connecting the first baffle 212 and the second baffle 213, the first baffle 212 is connected with the first partition plate 120 and is higher than the second baffle 213, the second baffle 213 is connected with the third partition plate 140, and a plurality of through holes 211 are formed in the second baffle 213. In this way, the condensed water overflowed from the first partition plate 120 into the second water tank 190 is mixed in the water mixing tank formed by the second baffle 213, the third baffle 214, and the third partition plate 140, so that the condensed water and the tap water can be mixed sufficiently.

[0034] With reference to Figure 1 , the condensed water collecting tank 100 further comprises a collection plate 220 connected with the third baffle 214 and the third partition plate 140, the height of the collection plate 220 near the third baffle 214 and the third partition plate 140 is higher than the height of the center of the collection plate 220, and a collection hole 221 is formed in the center of the collection plate 220, so that the condensed water overflowed from the third baffle 214 flows to the collection hole 221 from the third baffle 214, and then flows into the water mixing tank through the collection hole 221. In this way, the time for the condensed water and the tap water to flow into the water mixing tank is slowed down, so that the condensed water and the tap water can be mixed sufficiently.

[0035] With reference to Figure 1The condensate water collecting tank 100 further comprises a fourth partition plate 230 extending from the top to the bottom of the tank body 110, the fourth partition plate 230 is located between the third baffle 214 and the third partition plate 140, and the tap water inlet pipe 160 is located between the fourth partition plate 230 and the third partition plate 140.

[0036] With reference to Figure 1 The condensate water collecting tank 100 further comprises a flow sensor 240 arranged on the top of the first partition plate 120, through which it can be detected whether the water in the first water tank 180 overflows, i.e. whether the water level in the first water tank 180 is higher than the first partition plate 120.

[0037] With reference to Figure 1 The condensate water collecting tank 100 further comprises a second condensate water inlet pipe 250 communicating with the top of the tank body 110, the second condensate water inlet pipe 250 is located directly above the fourth partition plate 230 and the third baffle 214. By arranging the second condensate water inlet pipe 250, when the water level of the condensate water in the first water tank 180 is lower than the first partition plate 120, the condensate water can be directly supplied into the second water tank 190 through the second condensate water inlet pipe 250, so that when the condensate water starts to be supplied out of the condensate water collecting tank 100, the condensate water can be quickly obtained without waiting for the condensate water in the first water tank 180 to be higher than the first partition plate 120 before it can be supplied out, thereby shortening the response time of the condensate water collecting tank 100.

[0038] With reference to Figure 1 The condensate water collecting tank 100 further comprises a water replenishment pipe 260 communicating with the first water tank 180, through which the excess condensate water in the first water tank 180 can be directly discharged without entering the radiant cooling system.

[0039] With reference to Figure 1 The condensate water collecting tank 100 further comprises a tap water replenishment pipe 270 communicating with the top of the first water tank 180.

[0040] With reference to Figure 1 The condensate water collecting tank 100 further comprises a condensate water inlet main pipe 280 connected with the first condensate water inlet pipe 150 and the second condensate water inlet pipe 250. The condensate water collecting tank 100 further comprises a first flow meter 290 and a first thermometer 300 arranged on the condensate water inlet main pipe 280, a second thermometer 310 arranged on the tap water inlet pipe 160, and a third thermometer 320 arranged on the condensate water outlet pipe 170.

[0041] With reference to Figure 1The condensate collecting tank 100 further comprises a fourth temperature meter 330 disposed between the second partition 130 and the third partition 140 for measuring the temperature of the mixed water flowing into the third water tank 200.

[0042] Referring to Figure 1 The condensate collecting tank 100 further comprises a first flow regulating valve 340 disposed on the first condensate inlet pipe 150, a second flow regulating valve 350 disposed on the second condensate inlet pipe 250, a third flow regulating valve 360 disposed on the tap water inlet pipe 160, and a fourth flow regulating valve 370 disposed on the make-up water pipe 260.

[0043] The working process of the condensate collecting tank 100 is as follows:

[0044] When the flow of the condensate inlet pipe 280 is small, or the generated condensate just meets the demand of the radiant cooling area, the first flow regulating valve 340 disposed on the first condensate inlet pipe 150 is closed, the second flow regulating valve 350 disposed on the second condensate inlet pipe 250 is opened, the third flow regulating valve 360 disposed on the tap water inlet pipe 160 is opened, the fourth flow regulating valve 370 disposed on the make-up water pipe 260 is closed, and the condensate at the condensate inlet pipe 280 flows through the second condensate inlet pipe 250, and then flows into the upper part of the collecting plate 220, the tap water flows into the upper part of the collecting plate 220, the tap water and the condensate flow into the mixing tank through the collecting holes 221 of the collecting plate 220, and then flow into the second water tank 190 through the through holes 211 on the second partition 130, the water at the bottom of the second water tank 190 flows into the third water tank 200 through the gap between the third partition 140 and the second partition 130, and the water at the bottom of the third water tank 200 flows out through the condensate outlet pipe 170.

[0045] When the flow rate of the condensate water inlet pipe 280 exceeds the requirement of the radiant cooling area, and the water level in the first water tank 180 is lower than the height of the first partition 120, the first flow regulating valve 340 on the first condensate water inlet pipe 150 is opened, the second flow regulating valve 350 on the second condensate water inlet pipe 250 is opened, the third flow regulating valve 360 on the tap water inlet pipe 160 is opened, and the fourth flow regulating valve 370 on the make-up water pipe 260 is closed. The condensate water at the second condensate water inlet pipe 250 flows into the upper part of the collection plate 220, the tap water from the tap water inlet pipe 160 flows into the upper part of the collection plate 220, and the tap water and the condensate water flow into the mixing tank through the collection holes 221 of the collection plate 220, and then flow into the second water tank 190 through the through holes 211 on the second baffle 213. The water at the bottom of the second water tank 190 flows into the third water tank 200 through the gap between the third partition 140 and the second partition 130, and the water at the bottom of the third water tank 200 flows out through the condensate water outlet pipe 170. The condensate water at the first condensate water inlet pipe 150 flows into the first water tank 180 and is collected in the first water tank 180.

[0046] When the flow rate of the condensate water inlet pipe 280 exceeds the requirement of the radiant cooling area, and the water level in the first water tank 180 is higher than the height of the first partition 120, the first flow regulating valve 340 on the first condensate water inlet pipe 150 is opened, the second flow regulating valve 350 on the second condensate water inlet pipe 250 is closed, the third flow regulating valve 360 on the tap water inlet pipe 160 is opened, and the fourth flow regulating valve 370 on the make-up water pipe 260 is opened. The water overflowing from the first water tank 180 into the second water tank 190 and the tap water from the tap water inlet pipe 160 flow into the upper part of the collection plate 220, and the tap water and the condensate water flow into the mixing tank through the collection holes 221 of the collection plate 220, and then flow into the second water tank 190 through the through holes 211 on the second baffle 213. The water at the bottom of the second water tank 190 flows into the third water tank 200 through the gap between the third partition 140 and the second partition 130, and the water at the bottom of the third water tank 200 flows out through the condensate water outlet pipe 170. The condensate water at the first condensate water inlet pipe 150 flows into the first water tank 180 and is collected in the first water tank 180. At the same time, the fourth flow regulating valve 370 on the make-up water pipe 260 is opened, so that the condensate water exceeding the requirement of the radiant cooling area flows out from the make-up water pipe 260.

[0047] Embodiment two,

[0048] The embodiment provides a temperature control method for controlling the condensate water collecting tank 100 in embodiment one to output condensate water with a constant temperature, which comprises the following steps:

[0049] The flow rate Ql of the condensate water inlet pipe 280 and the temperature Tl of the condensate water at the condensate water inlet pipe 280 are measured, the temperature T2 of the tap water at the tap water inlet pipe 160 is measured, the temperature T3 of the mixed water at the condensate water outlet pipe 170 is measured, the flow rate Q6 of the mixed water flowing through the condensate water outlet pipe 170 is calculated, the make-up water amount Q4 of the tap water inlet pipe 160, the flow rate Q5 of the condensate water at the make-up water pipe 260, and the flow rates Q2 of the first condensate water inlet pipe 150 and Q3 of the second condensate water inlet pipe 250 are calculated, and the opening degree of the first flow rate adjusting valve 340, the opening degree of the second flow rate adjusting valve 350, the opening degree of the third flow rate adjusting valve 360, and the opening degree of the fourth flow rate adjusting valve 370 are adjusted according to the calculated Q5, Q4, Q2, and Q3.

[0050] When the Ql is less than or equal to a predetermined value and the radiant function system is working, i.e., the amount of the condensate water generated is less, or the generated condensate water just bears the radiant cooling area, the first flow rate adjusting valve 340 on the first condensate water inlet pipe 150 is closed, the second flow rate adjusting valve 350 on the second condensate water inlet pipe 250 is opened, the third flow rate adjusting valve 360 at the tap water inlet pipe 160 is opened, the fourth flow rate adjusting valve 370 arranged at the make-up water pipe 260 is closed, and Q4 and Q3 are calculated according to the following formula.

[0051] Ql = Q3

[0052] Ql · Tl + Q4 · T2 = Q6 · T3

[0053] Ql + Q4 = Q6

[0054] Wherein, Q6 is the flow rate of the mixed water flowing through the condensate water outlet pipe 170, and when the radiant cooling system is working stably, the value of Q6 · T3 can be calculated according to the load of the radiant cooling system and the set temperature value, and since T3 can be measured, Q6 can also be calculated.

[0055] When the Ql is greater than a predetermined value and the radiant function system is working, and the water level in the first water tank 180 is lower than the height of the first partition plate 120, the first flow rate adjusting valve 340 on the first condensate water inlet pipe 150 is opened, the second flow rate adjusting valve 350 on the second condensate water inlet pipe 250 is opened, the third flow rate adjusting valve 360 at the tap water inlet pipe 160 is opened, the fourth flow rate adjusting valve 370 arranged at the make-up water pipe 260 is closed, and Q4, Q2, and Q3 are calculated according to the following formula.

[0056] Ql = Q2 + Q3

[0057] Q3 · Tl + Q4 · T2 = Q6 · T3

[0058] Q3 + Q4 = Q6

[0059] Q6 is the flow rate of the mixed water flowing through the condensate water drain pipe 170, and when the radiant cooling system is working stably, the value of Q6-T3 can be calculated by the load of the radiant cooling system and the set temperature value. Since T3 can be measured, Q6 can also be calculated.

[0060] In this embodiment, the set temperature value of the radiant cooling system is preferably 16°C.

[0061] When Q1 is greater than a predetermined value and the radiant function system is working, and the water level in the first water tank 180 is higher than the height of the first partition 120, the first flow regulating valve 340 on the first condensate water inlet pipe 150 is opened, the second flow regulating valve 350 on the second condensate water inlet pipe 250 is closed, the third flow regulating valve 360 at the tap water inlet pipe 160 is opened, the fourth flow regulating valve 370 provided on the water replenishing pipe 260 is opened, and Q4, Q2 and Q5 are calculated according to the following formulae.

[0062] Q1 = Q2

[0063] Q2-T1 + Q4-T2 = Q5-T1 + Q6-T3

[0064] Q1 + Q4 = Q5 + Q6

[0065] Q6 is the flow rate of the mixed water flowing through the condensate water drain pipe 170, and when the radiant cooling system is working stably, the value of Q6-T3 can be calculated by the load of the radiant cooling system and the set temperature value. Since T3 can be measured, Q6 can also be calculated.

[0066] When the radiant function system is not working, the first flow regulating valve 340 of the first condensate water inlet pipe 150 is opened, the second flow regulating valve 350 of the second condensate water inlet pipe 250 is closed, the third flow regulating valve 360 at the tap water inlet pipe 160 is closed, the fourth flow regulating valve 370 provided on the water replenishing pipe 260 is opened, and Q2 and Q5 are calculated according to the following formulae.

[0067] Q1 = Q2

[0068] Q2 = Q5

[0069] Embodiment Three,

[0070] This embodiment also provides a condensate water recovery system having the condensate water collecting tank 100 in the above-mentioned Embodiment One.

[0071] Reference Figure 2 , Figure 2is a schematic view of a condensate water recovery system in the third embodiment of the present application, which comprises a condensate water collecting tank 100, a refrigeration terminal 410 of a radiant cooling system in communication with a condensate water drain pipe 170 of the condensate water collecting tank 100, and a cooling water tower 420 in communication with the refrigeration terminal 410 of the radiant cooling system.

[0072] By communicating the condensate water drain pipe 170 of the condensate water collecting tank 100 with the refrigeration terminal 410 of the radiant cooling system, the refrigeration terminal 410 of the radiant cooling system can be normally operated by providing refrigerant to the refrigeration terminal 410 of the radiant cooling system through the condensate water collecting tank 100, so that the energy of the condensate water can be fully utilized.
