技术领域technical field
本实用新型涉及一种采用间接蒸发方式的流体冷却/冷凝装置，属于制冷、空调与化工领域，特别适用于蒸发式冷凝器和闭式冷却塔。The utility model relates to a fluid cooling/condensing device adopting an indirect evaporation method, which belongs to the fields of refrigeration, air conditioning and chemical industry, and is especially suitable for evaporative condensers and closed cooling towers.
背景技术Background technique
冷却塔是制冷、空调与化工领域的常用冷却设备，可以将制冷机排出的高温冷却水冷却，制取略高于空气湿球温度的冷却水，但是常规开式冷却塔由于与外界直接接触，在***长期运行时，容易出现水质恶化、盐分浓缩、飘水量大等问题，对制冷机组的寿命和效率都造成一定程度的影响，同时在低温季节难以实现提供零费用冷冻水(free cooling)的功能。Cooling tower is a common cooling equipment in refrigeration, air conditioning and chemical industry. It can cool the high-temperature cooling water discharged from the refrigerator to produce cooling water slightly higher than the wet bulb temperature of the air. However, due to direct contact with the outside world, the conventional open cooling tower During the long-term operation of the system, problems such as water quality deterioration, salt concentration, and large floating water are prone to occur, which will have a certain impact on the life and efficiency of the refrigeration unit. At the same time, it is difficult to provide zero-cost frozen water (free cooling) in low-temperature seasons. Function.
闭式冷却塔的出现很好的解决了上述弊端，其采用间壁换热器实现了蒸发冷却介质与制冷***被冷却介质的隔离，既保证了制冷***被冷却介质的品质，又避免了冷却水等冷却介质的飘出，同时还可以在外界低气温条件下，停止冷却介质的喷淋，仅开启冷却塔的风机，即可转化为风冷冷却塔制取零费用冷冻水，使冬季需要供冷的空调***不用开冷水机组就能提供空调用冷冻水。但目前的闭式冷却塔，采用循环水喷淋，冷却水等被冷却介质的温度只能降至外界气温湿球温度以上，导致夏季运行的冷水机组等设备的效率降低。The emergence of the closed cooling tower has solved the above disadvantages very well. It uses the partition wall heat exchanger to realize the isolation of the evaporative cooling medium and the cooling medium of the refrigeration system, which not only ensures the quality of the cooling medium of the refrigeration system, but also avoids the cooling of cooling water. Wait for the cooling medium to float out, and at the same time, it can stop the spraying of the cooling medium under the condition of low external temperature, and only turn on the fan of the cooling tower to convert it into an air-cooled cooling tower to produce zero-cost frozen water, so that the winter needs to supply The cold air conditioning system can provide chilled water for air conditioning without turning on the chiller. However, the current closed cooling tower uses circulating water spraying, and the temperature of the cooling medium such as cooling water can only be lowered to above the wet bulb temperature of the outside air temperature, resulting in a reduction in the efficiency of equipment such as chillers operating in summer.
为提供温度更低的冷却水，我国专利ZL02202739.4公开了一种采用间接蒸发方式降低喷淋水温的技术方案，实现了低成本制取高温冷水之目的，为干燥地区应用温湿度独立控制空调***方式提供了廉价的冷源。但该技术方案中，空气与被冷却介质水直接接触，存在普通开式冷却塔的弊端，特别是在低气温条件下不能提供零费用冷冻水。In order to provide cooling water with a lower temperature, Chinese patent ZL02202739.4 discloses a technical solution that uses indirect evaporation to reduce the temperature of spray water, which achieves the purpose of producing high-temperature cold water at low cost, and applies temperature and humidity independent control of air conditioning in dry areas. The system approach provides an inexpensive cooling source. However, in this technical solution, the air is in direct contact with the cooled medium water, which has the disadvantages of ordinary open cooling towers, especially in the low temperature conditions that cannot provide zero-cost chilled water.
另一方面，蒸发式冷凝器在高温制冷剂、化工流体的冷却、冷凝过程中得到广泛应用。蒸发式冷凝器虽然在低气温条件下，通过停止冷却介质水的喷淋，即可转化为风冷式冷凝器，但在夏季运行时，蒸发式冷凝器的冷却/冷凝效率受环境空气湿球温度的制约，不能将被冷却介质的温度进一步降低。On the other hand, evaporative condensers are widely used in the cooling and condensation process of high-temperature refrigerants and chemical fluids. Although the evaporative condenser can be converted into an air-cooled condenser by stopping the spraying of the cooling medium water under low temperature conditions, the cooling/condensing efficiency of the evaporative condenser is affected by the ambient air wet bulb during operation in summer. Due to temperature constraints, the temperature of the cooled medium cannot be further reduced.
鉴于上述原因，迫切需要提供一种在夏季比闭式冷却塔和蒸发冷凝器的冷却效果更好、被冷却介质温度更低、且冬季仍可实现被冷却介质降温功能的水、制冷剂、化工流体等液相流体的冷却和/或气相流体的冷凝装置，弥补目前闭式冷却塔和蒸发式冷凝器存在的缺陷。In view of the above reasons, it is urgent to provide a kind of water, refrigerant, chemical industry which has a better cooling effect than closed cooling towers and evaporative condensers in summer, a lower temperature of the cooled medium, and can still realize the cooling function of the cooled medium in winter. The cooling device for liquid-phase fluid such as fluid and/or the condensing device for gas-phase fluid makes up for the defects existing in current closed cooling towers and evaporative condensers.

The feature is that an air-water heat exchanger 5 is arranged at the air inlet 10 , and the water side of the air-water heat exchanger is connected to the pipeline of the water pump 6 and the shower 3 .
本实用新型中，所述的空气-水换热器宜采用对称布置。In the utility model, the air-water heat exchangers should be symmetrically arranged.

Fillers 7 are arranged in the space around the partitioned wall heat exchanger. The dividing wall heat exchanger can use water or solution as the cooling medium; the cooled/condensed medium in the dividing wall heat exchanger can be liquid, gas or two-phase fluid.
本实用新型由于采用了上述技术方案，在夏季使水等被冷却单相流体的出液温度进一步降低，延长零费用冷冻水功能的使用时间，进一步降低制冷***和化工流体***的冷凝温度和制冷剂、化工流体的出液温度，实现空调、制冷和化工***的节能运行。Due to the adoption of the above-mentioned technical scheme, the utility model can further reduce the outlet temperature of water and other cooled single-phase fluids in summer, prolong the use time of the zero-cost frozen water function, and further reduce the condensation temperature and refrigeration temperature of refrigeration systems and chemical fluid systems. The outlet temperature of chemical fluids can be adjusted to realize energy-saving operation of air-conditioning, refrigeration and chemical systems.
具体表现在：①相比于常规的闭式冷却塔，本实用新型在略微增加成本的前提下，能够在夏季提高冷却效率，使水等被冷却单相流体的出液温度降低；在低外温环境下，停止水泵运转和喷淋器喷淋，只运行风机即可实现被冷却单相流体的降温目的。由此可知，在夏季通过间接蒸发冷却进一步降低被冷却单相流体的出液温度，在过渡季和冬季通过间接蒸发冷却或风冷方式提供低温的单相流体，减少了制冷机的运行时间，对于空调、化工等***的节能运行具有实用价值；②相对于蒸发式冷凝器而言，采用本实用新型的技术方案使高温气体或气液两相流体冷凝时，在夏季可使制冷***和化工冷却***的冷凝温度进一步降低，以降低***的能源消耗；在低温环境温度下，停止水泵运转和喷淋器喷淋，只运行风机即可实现高温气体或气液两相流体的冷凝、过冷之目的。The specific performance is as follows: ①Compared with the conventional closed cooling tower, the utility model can improve the cooling efficiency in summer under the premise of slightly increasing the cost, so that the outlet temperature of the cooled single-phase fluid such as water can be reduced; In a low-temperature environment, stop the operation of the water pump and the spraying of the sprinkler, and only run the fan to achieve the purpose of cooling the single-phase fluid to be cooled. It can be seen that in the summer, the outlet temperature of the cooled single-phase fluid is further reduced by indirect evaporative cooling, and the low-temperature single-phase fluid is provided by indirect evaporative cooling or air cooling in the transition season and winter, which reduces the operating time of the refrigerator. It has practical value for the energy-saving operation of air-conditioning, chemical and other systems; ② Compared with the evaporative condenser, when the technical solution of the utility model is used to condense high-temperature gas or gas-liquid two-phase fluid, the refrigeration system and chemical industry can be condensed in summer.

本实用新型提出的间接蒸发式冷却/冷凝装置在夏季使用时的冷却/冷凝效果与环境空气的相对湿度有关，湿度越低，冷却效果越好，所以特别适合于相对干燥地区的单相或气液两相流体的冷却/冷凝之用。The cooling/condensing effect of the indirect evaporative cooling/condensing device proposed by the utility model is related to the relative humidity of the ambient air when used in summer. The lower the humidity, the better the cooling effect, so it is especially suitable for single-phase or gas Cooling/condensation of liquid two-phase fluids.

Below in conjunction with accompanying drawing 1 concrete structure of the utility model and working process will be further described.
实施例1：Example 1:
如图1所示，本实用新型提供的一种间接蒸发式冷却/冷凝装置，该装置包括风机1、壳体2、喷淋器3、间壁式换热器4、水泵6和集水盘8；所述的风机设置在壳体的顶端，所述的喷淋器设置在壳体内的上部，间壁式换热器设置在喷淋器3的下部，在间壁式换热器下面的壳体壁面上设有进风口10，所述的集水盘设置在壳体的底部，集水盘8上设置有补水口9，集水盘通过管道与集水盘下部的水泵6入口连接，水泵6出口通过管路与喷淋器3连接；在所述的进风口10处设置空气-水换热器5，空气-水换热器水侧接入水泵6与喷淋器3的管路中。As shown in Figure 1, the utility model provides an indirect evaporative cooling/condensing device, which includes a fan 1, a housing 2, a shower 3, a partition heat exchanger 4, a water pump 6 and a water collecting tray 8 The fan is arranged on the top of the housing, the shower is arranged on the upper part of the housing, the partition heat exchanger is arranged on the bottom of the shower 3, and the wall of the housing below the partition heat exchanger There is an air inlet 10 on the top, the water collecting tray is arranged at the bottom of the housing, and the water collecting tray 8 is provided with a water supply port 9, and the water collecting tray is connected to the inlet of the water pump 6 at the lower part of the water collecting tray through a pipe, and the outlet of the water pump 6 It is connected to the shower 3 through pipelines; an air-water heat exchanger 5 is arranged at the air inlet 10 , and the water side of the air-water heat exchanger is connected to the pipeline of the water pump 6 and the shower 3 .
本实用新型中，空气-水换热器可采用两个或多个，宜采用对称布置。In the utility model, two or more air-water heat exchangers can be used, and a symmetrical arrangement should be adopted.
本实用新型所述间壁式换热器采用由光管和/或翅片管构成的盘管式换热器。在所述间壁式换热器周围空隙中设置填料7。该间壁式换热器可采用水或溶液作为冷却介质；间壁式换热器内的被冷却/冷凝介质可为液体、气体或两相流体。The wall heat exchanger described in the utility model adopts a coil heat exchanger composed of bare tubes and/or finned tubes. Fillers 7 are arranged in the space around the partitioned wall heat exchanger. The dividing wall heat exchanger can use water or solution as the cooling medium; the cooled/condensed medium in the dividing wall heat exchanger can be liquid, gas or two-phase fluid.
在上述间接蒸发式冷却/冷凝装置中，当进入间壁式换热器4中的被冷却介质为水时，该装置即可作为空调***冷水机组的间接蒸发闭式冷却塔。根据室外气温和***的实际需要有以下三种运行模式：In the above-mentioned indirect evaporative cooling/condensing device, when the cooled medium entering the partition wall heat exchanger 4 is water, the device can be used as an indirect evaporative closed cooling tower for the water chiller of the air conditioning system. According to the outdoor air temperature and the actual needs of the system, there are the following three operating modes:
(1)运行模式一：夏季冷水机组制冷运行时，水泵6开启，喷淋循环水，从冷水机组流出的冷却水经被冷却介质入口12进入间壁式换热器4内的水通道，将热量散至喷淋水中达到降温效果，再经被冷却介质出口13返回冷水机组；环境空气在风机1的驱动下先通过空气-水换热器5预冷，随后进入壳体2内与吸收了热量的喷淋水在间壁式换热器4外部或/和填料7内直接进行热湿交换，喷淋水被降温，靠重力落入集水盘8内循环利用，空气以高温高湿的排风11状态排出壳体2；集水盘8内的水因部分蒸发逐渐减少，再由补水口9进行补水，以保证集水盘8内的水位恒定；(1) Operation mode one: when the chiller is running in cooling in summer, the water pump 6 is turned on to spray circulating water, and the cooling water flowing out from the chiller enters the water channel in the partition heat exchanger 4 through the inlet 12 of the cooled medium, and transfers heat Scatter into the spray water to achieve the cooling effect, and then return to the chiller through the outlet 13 of the cooled medium; the ambient air is pre-cooled by the air-water heat exchanger 5 under the drive of the fan 1, and then enters the shell 2 to absorb heat The spray water is directly exchanged with heat and moisture outside the partition wall heat exchanger 4 or/and inside the filler 7, the spray water is cooled down, and falls into the water collection tray 8 by gravity for recycling, and the air is exhausted with high temperature and high humidity. 11 The state is discharged from the shell 2; the water in the water collection tray 8 is gradually reduced due to partial evaporation, and then replenished by the water supply port 9 to ensure that the water level in the water collection tray 8 is constant;
(2)运行模式二：在过渡季室外气温不高但空调***仍需要供冷的工况下，将间壁式换热器4的水直接切换到空调***的冷冻水环路中，以夏季工况的模式运行闭式冷却塔，从而实现零费用冷却供冷效果。(2) Operation mode 2: In the transitional season when the outdoor temperature is not high but the air conditioning system still needs to provide cooling, the water in the partition heat exchanger 4 is directly switched to the chilled water loop of the air conditioning system, and the summer work The closed cooling tower can be operated in the normal mode, so as to achieve zero-cost cooling and cooling effect.
(3)运行模式三：当建筑在冬季仍需供冷时，如果室外气温足够低，在上述运行模式二基础上，关闭水泵6，停止循环水喷淋，风机1仍然运行，此时闭式冷却塔按照风冷换热器模式运行，壁式换热器4内的冷冻水与室外空气换热降温，向空调***提供冷水。这种风冷方式避免了冬季空气-水冷换热外部的结冰现象，能保证安全稳定的供冷效果。(3) Operation mode 3: When the building still needs to be cooled in winter, if the outdoor temperature is low enough, on the basis of the above operation mode 2, turn off the water pump 6, stop the circulating water spray, and the fan 1 is still running. At this time, the closed The cooling tower operates in the air-cooled heat exchanger mode, and the chilled water in the wall heat exchanger 4 exchanges heat with the outdoor air for cooling, and provides cold water to the air-conditioning system. This air-cooling method avoids the freezing phenomenon outside the air-water cooling heat exchange in winter, and can ensure a safe and stable cooling effect.
当进入间壁式换热器4中被冷却介质是水以外的其他液体时，该装置仍为间接蒸发闭式冷却塔，可使被冷却介质得到有效地降温，其运行模式与冷却水的闭式冷却塔完全相同。When the cooled medium entering the partition wall heat exchanger 4 is liquid other than water, the device is still an indirect evaporative closed cooling tower, which can effectively cool the cooled medium, and its operation mode is the same as that of the closed cooling water cooling tower. Cooling towers are exactly the same.
由此可见，本实用新型技术方案应用于闭式冷却塔时，相比于常规闭式冷却塔而言，在略微增加成本的前提下，能够在夏季提高闭式冷却塔的冷却效率，使水等被冷却单相流体的出液温度降低；在低外温环境下，停止水泵6运转和喷淋器3喷淋，只运行风机1即可实现被冷却单相流体的降温目的，减少了制冷机的运行时间，对于空调、化工等***的节能运行具有实用价值。It can be seen that when the technical solution of the utility model is applied to the closed cooling tower, compared with the conventional closed cooling tower, the cooling efficiency of the closed cooling tower can be improved in summer on the premise of slightly increasing the cost, so that the water Wait until the outlet temperature of the single-phase fluid to be cooled decreases; in a low external temperature environment, stop the operation of the water pump 6 and the spraying of the sprinkler 3, and only run the fan 1 to achieve the purpose of cooling the single-phase fluid to be cooled, reducing the cooling time. It has practical value for the energy-saving operation of air-conditioning, chemical and other systems.
实施例2：Example 2:
在本实用新型提供的上述间接蒸发式冷却/冷凝装置中，当间壁式换热器4中的被冷凝介质采用制冷剂等高温气体或气液两相流体时，该装置即可作为蒸气压缩式制冷***或化工***的间接蒸发式冷凝器。由于制冷***或化工冷却***一年四季都需要制冷，故一般有以下两种运行模式：In the above-mentioned indirect evaporative cooling/condensing device provided by the utility model, when the condensed medium in the partition wall heat exchanger 4 adopts a high-temperature gas such as a refrigerant or a gas-liquid two-phase fluid, the device can be used as a vapor compression type Indirect evaporative condensers for refrigeration systems or chemical systems. Since the refrigeration system or chemical cooling system needs to be refrigerated throughout the year, there are generally the following two operating modes:
(1)运行模式一：在夏季工况下，水泵6开启，喷淋循环水，进入间壁式换热器4内的制冷剂等高温气体或气液两相流体将热量散至喷淋水中达到冷凝效果。室外空气在风机1的驱动下，先通过空气-水换热器5预冷，随后进入壳体2内与吸收了热量的喷淋水在间壁式换热器4外部或/和填料7内直接进行热湿交换，喷淋水被降温，靠重力落入集水盘8循环利用，空气以高温高湿状态的排风11排出壳体2。此过程装置以蒸发式冷凝器状态运行；(1) Operation mode 1: In summer working conditions, the water pump 6 is turned on, and the circulating water is sprayed, and the high-temperature gas such as refrigerant or gas-liquid two-phase fluid entering the partition heat exchanger 4 dissipates heat to the spray water to achieve condensation effect. Driven by the fan 1, the outdoor air first passes through the air-water heat exchanger 5 for pre-cooling, and then enters the housing 2 and sprays water that has absorbed heat directly on the outside of the partition heat exchanger 4 or/and inside the filler 7. The heat and humidity exchange is carried out, the spray water is cooled down, and falls into the water collection tray 8 by gravity for recycling, and the air is discharged from the casing 2 with the high-temperature and high-humidity exhaust air 11 . The process unit operates as an evaporative condenser;
(2)运行模式二：在冬季如果到室外气温足够低时，关闭水泵6，停止循环水喷淋，风机1正常运行，通过风冷方式使间壁式换热器4内流动的制冷剂等高温气体或气液两相流体冷凝成液体。此过程装置以风冷式冷凝器状态运行。(2) Operation mode 2: In winter, if the outdoor temperature is low enough, turn off the water pump 6, stop the circulating water spraying, and the fan 1 will run normally, and the refrigerant flowing in the partition heat exchanger 4 will be kept at a high temperature by air cooling. A gas or a gas-liquid two-phase fluid condenses into a liquid. The process unit operates as an air-cooled condenser.
可见，本实用新型技术方案应用于蒸发式冷凝器时，相对于现有蒸发式冷凝器而言，本实用新型在夏季可使制冷***和化工冷却***的冷凝温度进一步降低；在低温环境温度下，停止水泵6运转和喷淋器3喷淋，只运行风机1即可将高温气体或气液两相流体冷凝成饱和或过冷液体，可减少制冷***和化工冷却***的能源消耗。It can be seen that when the technical solution of the utility model is applied to the evaporative condenser, compared with the existing evaporative condenser, the utility model can further reduce the condensation temperature of the refrigeration system and the chemical cooling system in summer; , stop the operation of the water pump 6 and the spraying of the sprinkler 3, and only run the fan 1 to condense the high-temperature gas or the gas-liquid two-phase fluid into a saturated or supercooled liquid, which can reduce the energy consumption of the refrigeration system and the chemical cooling system.
