The utility model patent relates to a brand-new water storage air-conditioning system, which saves the huge outdoor cooling tower structure, perfectly combines the building's air-conditioning system with the landscape fountain, and integrates the original system into evaporative cooling at the same time, which reduces the system energy consumption. It also realizes the aesthetics of the structure, saves the floor area, reduces the operating noise, saves energy and is environmentally friendly.

Background technique

Water storage air-conditioning technology is a technology that uses sensible heat of water to store cold energy: it is made of refrigeration equipment during the time period when no cooling capacity is needed or less cooling capacity is needed (when the power grid is at a low point at night, and the air conditioning load is also at a low point). The low-temperature water is stored and then used during the peak period of air-conditioning or process cooling (when the power grid peaks during the day, it is usually also the peak of the air-conditioning load) to meet the demand. As an effective way to shift peaks and valleys of electric power, it can achieve the effects of economical operation, energy saving and environmental protection, and has been widely used. The current water storage technology mainly adopts double-slot or multi-slot type, labyrinth type, single-slot diaphragm type, single-slot temperature layered type, etc. Usually, no matter what type of cooling equipment is installed outdoors, the cooling equipment is inseparable. Cooling towers, and the larger the design capacity of the system, the larger the volume and number of cooling towers, which will inevitably have negative impacts on users and the surrounding environment, mainly including: (1) Cooling towers occupy too much building space (roof or (2) The continuous high-frequency noise during the operation of the cooling tower interferes with the work and life of the surrounding people. Therefore, on the premise of not reducing the operating efficiency of the system, it is of great practical value for large-scale water storage air-conditioning systems to effectively solve the excessive space occupied by the cooling tower and reduce the operating noise of the outdoor cooling tower.

Working process and working principle of the present utility model are:

Embodiment 1 (cold storage operation mode):

In this embodiment, the cold storage operation mode is selected for illustration. This operation mode includes three main cycles: cooling water cycle, refrigerant cycle, and cold storage cycle;

Cooling water circulation (see line A-A in Figure 2): As shown in Figure 2, the cooling water pump 5 transports the cooling water at a lower temperature cooled in the landscape pool 7 where the landscape fountain is located to the condensing heat exchanger 4 and the heat exchanger inside the chiller On the other side, the high-temperature and high-pressure superheated refrigerant to be condensed performs heat exchange, absorbs the heat of the high-temperature refrigerant and heats up, and then flows to the landscape fountain nozzle 6 to be atomized and sprayed out, and the pressure generated by the operation of the cooling water pump 5 is released at the outlet of the atomized nozzle At the same time of atomization, flash evaporation occurs instantaneously, so that the heated cooling water is cooled to a lower temperature cooling water and scattered in the landscape pool 7 where the landscape fountain is located, and then enters the next cycle under the action of the cooling water pump 5 and so on. Until the system is shut down, atomization and flash evaporation are applied in this cycle, which greatly enhances the heat transfer efficiency of evaporative cooling, improves cooling efficiency and saves the power consumption of fans when using cooling towers, and generally improves the operating efficiency of the entire system , energy saving and environmental protection.

Refrigeration medium cycle (see line B-B in Figure 3): As shown in Figure 3, the low-temperature and low-pressure circulating refrigerant in the central air-conditioning system is compressed into high-temperature and high-pressure superheated steam at the compressor 1 inside the chiller and then enters the cold water The internal condensing heat exchanger 4 of the main engine performs heat exchange with the lower temperature cooling water pumped from the landscape pool 7 where the landscape fountain is located and releases heat to cool down. The internal throttling device 3 of the chiller is throttled and depressurized at 3 places to become a low-temperature and low-pressure unsaturated liquid, and then enters the evaporating heat exchanger 2 inside the chiller, and the cold and warm water pumped from the cold storage tank 12 inside 2 (about 11°C) for heat exchange, a large amount of heat is absorbed and vaporized to become a low-temperature and low-pressure circulating refrigerant, and finally enters the internal compressor 1 of the chiller again to be compressed, and the cycle is repeated until the system shuts down.

Cold storage cycle (see line C-C in Figure 2): As shown in Figure 2, before the cycle is opened, the electric valves 16, 17, and 18 are opened respectively, and the electric valves 14, 15, 19, and 20 are closed respectively, and the upper part of the cold storage tank 12 is higher The cold and warm water (about 11°C) is transported to the evaporative heat exchanger 2 inside the chiller under the action of the cold storage water pump 13, and the evaporative heat exchanger 2 inside the chiller performs convective exchange with the low-temperature and low-pressure unsaturated refrigerant The heat releases a large amount of heat, and cools down to refrigerated water at about 4°C, and then enters the lower part of the cold storage tank 12 through the electric valves 17 and 18, so that the 4°C frozen water can be continuously stored in the cold storage tank 12 until the cold storage tank 12 The cold and warm water (about 11°C) in the upper part is all turned into chilled water at 4°C. At this time, the cold storage tank 12 is full of cold storage, and the cold storage cycle is closed.

Embodiment 2 (direct cooling operation mode):

In this embodiment, the direct cooling operation mode is selected for illustration. This operation mode includes three main cycles: cooling water cycle, refrigerant cycle, and chilled water cycle; wherein, the cooling water cycle and refrigerant cycle have the same names as those in the above-mentioned cold storage operation mode. The cycle is exactly the same, so it will not be repeated here, and only the frozen water cycle will be described in detail below.

Chilled water cycle (see line D-D in Figure 3): As shown in Figure 3, before the cycle is started, the electric valves 14 and 19 are opened respectively, and the electric valves 15, 16, 17, 18, and 20 are closed respectively, and the water flows through the chiller to evaporate The heat exchanger 2 conducts convective heat exchange with the refrigerating medium. After the chilled water is cooled to about 7°C, under the action of the chilled water pump 10, it first passes through the electric valve 19, and then is sent to the air conditioner terminal device 8. Under the action of 8, the cooling capacity It is sent out to cool down the working spaces that need to be air-conditioned, and at the same time leaves the air-conditioning terminal device 8 to absorb heat and heat up to become cold and warm water at about 12°C, and finally enters the evaporative heat exchanger 2 inside the chiller through the electric valve 14 to exchange heat again and cool down to 7°C, such a reciprocating cycle achieves the cooling and cooling purpose of the central air conditioner.
