现有的热源塔及其构成的***中没有设置用于分离第一导热媒介中水的油水分离装置，而现有的热源塔中的第一导热媒介采用的是亲水性换热媒介，一般是防冻剂，而现有的防冻剂均为亲水性防冻剂，因此，在长时间飘逸过程中，由于会产生冷凝水，而冷凝水与亲水性防冻剂不易分离，在低温环境下冷凝水固化成冰，会导致管道堵塞甚至管道损坏，为了克服这个问题，现有解决方案是，配置溶液浓缩装置，这种浓缩装置实际一般采用加热蒸发或分子膜过滤的方式去除冷凝水，因此需要消耗大量能耗去排出水。The existing heat source tower and the system thereof are not provided with a water-water separation device for separating water in the first heat-conducting medium, and the first heat-conducting medium in the existing heat source tower adopts a hydrophilic heat-exchange medium, generally It is an antifreeze, and the existing antifreeze is a hydrophilic antifreeze. Therefore, in the long-term floating process, condensed water is generated, and the condensed water and the hydrophilic antifreeze are not easily separated, and condensed in a low temperature environment. In order to overcome this problem, the existing solution is to configure a solution concentrating device. The concentrating device generally uses heating evaporation or molecular membrane filtration to remove condensed water. Therefore, it is required to cure the water into ice.

The energy consumption and equipment cost of the first heat-conducting medium concentrating device are saved, and the energy-saving efficiency of the system is improved. Because the oil-water separation device is adopted, the first heat-conducting medium circulating in the heat-exchange filler channel can be a hydrophobic fluid. For example, some oil fluids. In this way, the original concentrating device can be eliminated, thereby reducing the problem of equipment cost and energy consumption. The heat source tower body in the present invention may start the heat source tower or the closed heat source tower; correspondingly, the heat exchange filler passage is a heat exchange filler passage of the open heat source tower or a heat exchanger passage of the closed heat source tower.

本发明的疏水性流体热源塔热泵***通过下述技术方案实现：疏水性流体热源塔热泵***，包括热源塔、热泵机组，热源塔、通过第一换热回路管内循环的第一导热媒介与热泵机组的蒸发器进行热交换，热源塔设置在第一换热回路管的路径上，第一换热回路管内循环有第一导热媒介，第一导热媒介从第一换热回路管流入热源塔、再从热源塔回流至第一换热回路管内，其特征在于，第一换热回路管和热源塔内循环有疏水性流体作为第一导热媒介。The hydrophobic fluid heat source tower heat pump system of the present invention is realized by the following technical scheme: a hydrophobic fluid heat source tower heat pump system, comprising a heat source tower, a heat pump unit, a heat source tower, a first heat conduction medium and a heat pump circulating through the first heat exchange loop tube The evaporator of the unit performs heat exchange, and the heat source tower is disposed on the path of the first heat exchange loop tube, and the first heat transfer medium is circulated in the first heat exchange loop tube, and the first heat transfer medium flows from the first heat exchange loop tube into the heat source tower, And returning from the heat source tower to the first heat exchange loop tube, wherein the first heat exchange loop tube and the heat source tower circulate a hydrophobic fluid as the first heat conduction medium.
在本结构中，制热状态下，热源塔与空气进行热交换，输出高温的第一导热媒介给热泵机组，热泵机组在吸热后输出低温的第一导热媒介给热源塔；热源塔中，空气遇到低温的第一导热媒介时，会使得低温的第一导热媒介吸热，变成高温的第一导热媒介，而空气中的水蒸汽遇到低温的第一导热媒介冷凝形成凝结水，高温的第一导热媒介与冷凝水混合流到热源塔底部，由于本发明采用疏水性流体作为第一导热媒介，因此会出现疏水性流体与冷凝水自然分层、分离的情形，这时，可以直接抽取疏水性流体进入到热泵机组参与热交换即可，不需要浓缩装置。而传统结构采用的防冻液作为第一导热媒介，随着冷凝水的不断增加，而防冻液又与水互溶，当冷凝水含量增加，防冻液的浓度降低后，会使的第一导热媒介的抗冻性降低，第一导热媒介会结冰，因此需要进行 对第一导热媒介进行浓缩，才能继续起到防冻的性能，这种技术必须采用浓缩装置进行浓缩处理，而现有技术中，采用浓缩装置每小时分离90L的凝结水需要20KW的能量，这种技术是极其耗能，相比本发明的技术，采用疏水性流体作为第一导热媒介，利用该媒介的疏水性，使得冷凝水与该第一导热媒介自然分层、分离，可直接获得该第一到热媒介进行循环参与热交换，其进入热泵机组的第一导热媒介中的水的含量可以占小于10％的比例，本发明利用物质的疏水性，达到自然分层、分离导热媒介与冷凝水的目的，以此解决高耗能的问题，降低设备成本。In the structure, in the heating state, the heat source tower exchanges heat with the air, and outputs a high temperature first heat conduction medium to the heat pump unit, and the heat pump unit outputs a low temperature first heat conduction medium to the heat source tower after the heat absorption; in the heat source tower, When the air encounters the low temperature first heat conduction medium, the low temperature first heat conduction medium absorbs heat and becomes a high temperature first heat conduction medium, and the water vapor in the air encounters the low temperature first heat conduction medium to condense to form condensed water. The high-temperature first heat-conducting medium is mixed with the condensed water and flows to the bottom of the heat source tower. Since the present invention uses the hydrophobic fluid as the first heat-conducting medium, the hydrophobic fluid and the condensed water naturally stratify and separate, and then, Directly extracting the hydrophobic fluid into the heat pump unit can participate in the heat exchange, and does not require a concentrating device. The antifreeze used in the traditional structure is used as the first heat conduction medium. As the condensed water increases, the antifreeze is mutually soluble with water. When the condensed water content increases and the concentration of the antifreeze decreases, the first heat transfer medium will be The frost resistance is reduced and the first heat transfer medium freezes, so it needs to be carried out The first heat-conducting medium is concentrated to continue the anti-freezing performance. This technique must be concentrated by a concentrating device. In the prior art, it takes 20 KW of energy to separate 90 L of condensate per hour by using a concentrating device. The technology is extremely energy-intensive. Compared with the technology of the present invention, a hydrophobic fluid is used as the first heat-conducting medium, and the hydrophobicity of the medium is utilized, so that the condensed water and the first heat-conducting medium are naturally layered and separated, and the first step can be directly obtained. When the heat medium is circulated and participates in heat exchange, the content of water entering the first heat transfer medium of the heat pump unit may account for less than 10%, and the present invention utilizes the hydrophobicity of the substance to achieve natural stratification, separation of the heat transfer medium and condensation. The purpose of water is to solve high energy consumption problems and reduce equipment costs.

实施例1 Example 1
如图1所示，疏水性流体热源塔热泵***，包括热源塔1、热泵机组，热源塔1通过第一换热回路管8内循环的第一导热媒介与热泵机组进行热交换，热源塔1设置在第一换热回路管8的路径上，第一换热回路管内循环有第一导热媒介，第一导热媒介从第一换热回路管流入热源塔1、再从热源塔1回流至第一换热回路管内，第一换热回路管和热源塔内循环有疏水性流体作为第一导热媒介。As shown in FIG. 1 , a hydrophobic fluid heat source tower heat pump system includes a heat source tower 1 and a heat pump unit. The heat source tower 1 exchanges heat with a heat pump unit through a first heat transfer medium circulating in the first heat exchange loop tube 8 , and the heat source tower 1 The first heat exchange medium is disposed in the first heat exchange circuit tube 8 and has a first heat conduction medium circulating therein. The first heat conduction medium flows from the first heat exchange circuit tube into the heat source tower 1 and then flows back from the heat source tower 1 to the first heat exchange medium. In a heat exchange circuit tube, a hydrophobic fluid is circulated in the first heat exchange loop tube and the heat source tower as a first heat conduction medium.
在本结构中，制热状态下，热源塔与空气进行热交换，输出高温的第一导热媒介给热泵机组，热泵机组在吸热后输出低温的第一导热媒介给热源塔；热源塔中，空气遇到低温的第一导热媒介时，会使得低温的第一导热媒介吸热，变成高温的第一导热媒介，而空气中的水蒸汽遇到低温的第一导热媒介冷凝形成凝结水，高温的第一导热媒介与冷凝水混合流到热源塔底部，由于本发明采用疏水性流体作为第一导热媒介，因此会出现疏水性流体与冷凝水分离的情形，这时，可以直接抽取疏水性流体进入到热泵机组参与热交换即可，不需要浓缩装置。而传统结构采用的防冻液作为第一导热媒介，随着冷凝水的不断增加，而防冻液又与水互溶，当冷凝水含量增加，防冻液的比例降低后，会使的第一导热媒介的抗冻性降低，因此需要进行对第一导热媒介进行浓缩，才能继续起到防冻的性能，这种技术必须采用浓缩装置进行浓缩处理，而现有技术中，采用浓缩装置，防冻液的浓缩速率为90L/h，每小时耗电20kw，即每小时分离90L凝结水需要20KW的能量，每升水需耗电近0.2度，1万平方米建筑面积使用普通热源塔中央空调，每小时会产生600升水，防冻液浓缩每小时耗电120度左右，这种技术极其耗能；而本发明采用疏水性流体作为第一导热媒介，利用该媒介的疏水性，使得冷凝水与该第一导热媒介自然分层、分离，可直接获得该第一导热媒介进行循环参与热交换，其进入热泵机组的第一导热媒介中的水的含量可以只占小于10％的比例，零能耗，本发明利用物质的疏水性，达到自然分层、分离导热媒介与冷凝水的目的，以此解决高耗能的问题并且还能防垢、防霜和融霜。 In the structure, in the heating state, the heat source tower exchanges heat with the air, and outputs a high temperature first heat conduction medium to the heat pump unit, and the heat pump unit outputs a low temperature first heat conduction medium to the heat source tower after the heat absorption; in the heat source tower, When the air encounters the low temperature first heat conduction medium, the low temperature first heat conduction medium absorbs heat and becomes a high temperature first heat conduction medium, and the water vapor in the air encounters the low temperature first heat conduction medium to condense to form condensed water. The high temperature first heat transfer medium is mixed with the condensed water and flows to the bottom of the heat source tower. Since the present invention uses the hydrophobic fluid as the first heat transfer medium, the hydrophobic fluid is separated from the condensed water, and the hydrophobicity can be directly extracted. The fluid enters the heat pump unit to participate in the heat exchange, and does not require a concentrating device. The antifreeze used in the traditional structure is used as the first heat conduction medium. As the condensed water increases, the antifreeze is mutually soluble with water. When the condensed water content increases and the proportion of the antifreeze liquid decreases, the first heat conduction medium will be The freeze resistance is reduced, so it is necessary to concentrate the first heat transfer medium to continue the antifreeze performance. This technique must be concentrated by a concentration device. In the prior art, the concentration rate of the antifreeze solution is used. It is 90L/h, and consumes 20kw per hour, that is, 20KW of condensate is required to separate 90L of condensed water per hour. The power consumption per liter of water is nearly 0.2 degrees. The building area of 10,000 square meters uses the central air conditioner of ordinary heat source tower, which will produce 600 per hour. Ascending water, antifreeze concentration consumes about 120 degrees per hour, this technology is extremely energy-intensive; while the present invention uses a hydrophobic fluid as the first heat-conducting medium, utilizing the hydrophobicity of the medium, so that the condensed water and the first heat-conducting medium naturally The stratification and separation can directly obtain the first heat conduction medium to circulate and participate in heat exchange, and the content of water entering the first heat conduction medium of the heat pump unit With only a proportion of less than 10% and zero energy consumption, the present invention utilizes the hydrophobicity of the substance to achieve the purpose of natural stratification, separation of the heat transfer medium and condensed water, thereby solving the problem of high energy consumption and also preventing scale and prevention. Frost and defrost.

现有的热源塔及其构成的***中没有设置用于分离第一导热媒介中水的油水分离装置，而现有的热源塔中的第一导热媒介采用的是亲水性换热媒介，一般是防冻剂，而现有的防冻剂均为亲水性防冻剂，因此，在长时间飘逸过程中，由于会产生冷凝水，而冷凝水与亲水性防冻剂不易分离，在低温环境下冷凝水固化成冰，会导致管道堵塞甚至管道损坏，为了克服这个问 题，现有解决方案是，配置溶液浓缩装置，这种浓缩装置实际一般采用加热蒸发或分子膜过滤的方式去除冷凝水，因此需要消耗大量能耗去排出水。The existing heat source tower and the system thereof are not provided with a water-water separation device for separating water in the first heat-conducting medium, and the first heat-conducting medium in the existing heat source tower adopts a hydrophilic heat-exchange medium, generally It is an antifreeze, and the existing antifreeze is a hydrophilic antifreeze. Therefore, in the long-term floating process, condensed water is generated, and the condensed water and the hydrophilic antifreeze are not easily separated, and condensed in a low temperature environment. Curing water into ice can cause blockage of pipes or even damage to pipes, in order to overcome this problem. The existing solution is to configure a solution concentrating device, which generally uses a method of heating evaporation or molecular membrane filtration to remove condensed water, and thus consumes a large amount of energy to discharge water.
本发明在热源塔本体结构的基础上，设置有油水分离装置，油水分离装置可以分离第一导热媒介中的水，可以将生产的冷凝水自动分离并排放，保持第一导热媒介相对稳定的浓度，节省了第一导热媒介浓缩装置的飘逸能耗和设备成本，提高了***的节能效率，而由于采用了油水分离装置，因此可以使得换热填料通道内流通的第一导热媒介为疏水性流体，例如一些疏水性油类流体。这样就可以取消原有的浓缩装置，达到降低设备费和能源消耗的问题。The invention is provided with an oil-water separation device on the basis of the structure of the heat source tower body, and the oil-water separation device can separate the water in the first heat-conducting medium, and can automatically separate and discharge the produced condensed water to maintain a relatively stable concentration of the first heat-conducting medium. The energy consumption and equipment cost of the first heat-conducting medium concentrating device are saved, and the energy-saving efficiency of the system is improved. Because the oil-water separation device is adopted, the first heat-conducting medium circulating in the heat-exchange filler channel can be a hydrophobic fluid. For example, some hydrophobic oil fluids. In this way, the original concentrating device can be eliminated, thereby reducing the problem of equipment cost and energy consumption.
优选的，热源塔本体内设置有喷洒第一导热媒介的喷洒装置13，喷洒装置13将第一导热媒介喷洒到换热填料通道内。Preferably, the heat source tower body is provided with a spraying device 13 spraying the first heat conducting medium, and the spraying device 13 sprays the first heat conducting medium into the heat exchange filler channel.
