[0018] A water tank level sensor S1 is also provided in the condensed water storage tank W1.

[0019] The landscape pool water supply module includes a landscape pool W2, a cooling tower overflow pipe L8 connected to an air conditioning cooling tower group is provided at the water inlet end of the landscape pool W2, a sprinkler pump P2 is provided in the landscape pool W2, the sprinkler pump P2 is connected to a sprinkler pipe L9, and a sprinkler W3 is connected to the end of the sprinkler pipe L9.

[0020] A water pool level sensor S2 is provided in the landscape water pool W2.

[0021] The condensate water inlet pipe L5 is connected to the condensate water supply pipe L6 by setting a condensate water pump P1. The condensate water inlet pipe L5 is on the left side of the condensate water pump P1, and the condensate water storage tank W1 is connected to the left side of the condensate water inlet pipe L5. The water tank level sensor S1 is set in the condensate water storage tank W1. The condensate water filter device E3 and the condensate water sterilization and disinfection device E4 are connected above the condensate water storage tank W1. The condensate water main collection pipe L4 is connected above the condensate water filter device E3, and the condensate water ring pipe L3 is connected above the condensate water main collection pipe L4. The condensate water vertical main pipe L2 is connected above the condensate water ring pipe L3, and each layer of the condensate water vertical main pipe L2 is connected to the condensate water branch pipe L1. The air conditioning terminal equipment E2 is connected to the condensate water vertical main pipe L2 through the condensate water branch pipe L1.

[0022] On the right side of the condensate pump P1 is the condensate supply pipe L6, and two cooling towers E1 are connected above the condensate supply pipe L6. Adjacent cooling towers E1 are connected through a cooling tower balancing pipe L7. A cooling tower overflow pipe L8 is connected below the cooling tower E1, and the lower end of the cooling tower overflow pipe L8 discharges into the landscape pool W2. A pool level sensor S2 is provided in the landscape pool W2. A sprinkler pump P2 is provided at the bottom of the landscape pool W2. A sprinkler pipe L9 is connected above the sprinkler pump P2, and the end of the sprinkler pipe L9 is connected to a sprinkler W3. The sprinkler W3 is used to water green plants and roads.

[0023] The control strategy of the above-mentioned central air-conditioning condensate recovery and comprehensive utilization system is as follows: In summer, when the central air-conditioning of offices, hotels, shopping malls and other properties starts cooling operation, the air-conditioning terminal equipment E2 will generate a large amount of condensate, which is collected to the condensate vertical main pipe L2 through the condensate branch pipe L1, and then collected to the condensate ring pipe L3, and finally collected to the condensate main collection pipe L4 to enter the condensate filter device E3. After being filtered and purified by the condensate filter device E3, the condensate enters the condensate sterilization and disinfection device E4, and the condensate is sterilized and disinfected in a conventional manner. The condensate after sterilization and disinfection is stored in the condensate storage tank W1. When the water tank level sensor S1 set in the condensate storage tank W1 senses that the water storage depth of the condensate storage tank W1 has reached the starting depth requirement of the condensate pump P1, the condensate pump P1 is started, and the condensate is lifted from the condensate storage tank W1 through the condensate inlet pipe L5 and the condensate pump P1, and then sent to the cooling tower E1 through the condensate supply pipe L6. After a large amount of low-temperature condensed water is mixed with the high-temperature cooling water in the cooling tower, the water supply temperature of the cooling water is reduced, and the performance of the central air-conditioning chiller is improved. The condensed water is sent to other cooling towers E1 through the cooling tower balance pipe L7 between the cooling towers E1. When the amount of condensed water added exceeds the amount of water added to the cooling tower E1, the condensed water flows through the last group of cooling towers E1 through the cooling tower overflow pipe L8 into the landscape pool W2. This design can ensure that the condensed water flowing into the cooling tower overflow pipe L8 has the highest temperature, making full use of the mixing effect of the low temperature of the condensed water.

[0024] Since the amount of condensed water is much larger than the amount of cooling water replenished by cooling tower E1, a large amount of mixed condensed water will flow into the landscape pool W2 from the overflow pipe L8 of the cooling tower, and mix with the landscape pool W2 to form pool water. When the pool level sensor S2 set on the landscape pool W2 senses that the water storage depth of the landscape pool W2 has reached the starting depth requirement of the sprinkler pump P2, the sprinkler pump P2 is started. At this time, the pool water is lifted by the sprinkler pump P2 and then sprayed to water points such as green plants or roads through the sprinkler pipe L9 and the sprinkler W3.
