Description
技术领域 technical field
本实用新型涉及空调技术领域,具体涉及一种主动式辐射板换热系统。 The utility model relates to the technical field of air conditioning, in particular to an active radiation plate heat exchange system.
背景技术 Background technique
辐射板是呈扁平板状的暖通空调设备,其将工作元件加热或制冷,达到向周边环境进行热辐射采暖或者冷辐射制冷的目的。以功能分类,可以分为热辐射板和冷辐射板。用来加热的介质主要有热水、蒸汽、燃气、燃油、电等,用来制冷的介质主要是冷水、蒸发剂(氟利昂、液氨)等。 The radiant panel is a flat plate-shaped HVAC equipment, which heats or cools the working elements to achieve the purpose of thermal radiation heating or cold radiation cooling to the surrounding environment. Classified by function, it can be divided into hot radiant panels and cold radiant panels. The medium used for heating mainly includes hot water, steam, gas, fuel oil, electricity, etc., and the medium used for cooling mainly includes cold water, evaporating agent (freon, liquid ammonia), etc.
与传统的空气对流式空调系统相比,辐射板系统主要是以辐射换热为主,垂直温度差相对较小,有助于提高室内使用的舒适度,也不存在使用对空气流式空调系统时室内机噪声大的问题,同时,辐射板系统还可以采用热水、冷水分别作为加热、制冷的介质,从而可以大幅降低能耗。 Compared with the traditional air convection air conditioning system, the radiant panel system is mainly based on radiation heat exchange, and the vertical temperature difference is relatively small, which helps to improve the comfort of indoor use, and there is no use of air convection air conditioning system At the same time, the radiant panel system can also use hot water and cold water as the medium for heating and cooling, which can greatly reduce energy consumption.
虽然辐射板系统的优势突出,但也有其自身的局限性。现有的辐射板系统,在夏季的制冷温度不宜过低,一般为16-18℃,过低的制冷温度会使得辐射板产生结露,影响室内卫生条件,但这就导致了辐射板的单位面积制冷换热能力较低,制冷效率不佳;而在冬季,虽然不存在结露的问题,但由于受到辐射加热换热效率的限制及舒适度的要求,加热温度也不宜过高,一般为26-32℃,否则过高温度的热能因无法完全向外辐射而在辐射板内聚集,容易加速内部器件老化,缩短使用寿命,且舒适度降低。因此,供冷、供热能力不足的因素,使得辐射板系统难以满足具有较大供冷、供热负荷的需求,从而大幅限制了辐射板系统在更多地区和领域的推广应用。 Although the advantages of the radiant panel system are outstanding, it also has its own limitations. In the existing radiant panel system, the cooling temperature in summer should not be too low, generally 16-18°C. If the cooling temperature is too low, the radiant panel will generate condensation, which will affect the indoor hygienic conditions. The area cooling and heat exchange capacity is low, and the cooling efficiency is not good; in winter, although there is no problem of condensation, due to the limitation of radiation heating heat exchange efficiency and comfort requirements, the heating temperature should not be too high, generally 26-32°C, otherwise the heat energy of too high temperature will accumulate in the radiant panel because it cannot be completely radiated outward, which will easily accelerate the aging of internal components, shorten the service life, and reduce the comfort. Therefore, the lack of cooling and heating capacity makes it difficult for the radiant panel system to meet the demand for large cooling and heating loads, which greatly limits the promotion and application of the radiant panel system in more regions and fields.

The radiant plate 10 has a flat heat exchange cavity 11, the bottom surface of the heat exchange cavity 11 is a radiation surface; the inner cavity top surface of the heat exchange cavity 11 is laid with an insulating material layer 12; The upper bunk is provided with a number of heat exchange pipes 13 arranged in parallel to each other, and there is a ventilation gap 14 between the heat exchange pipes 13 and the insulation material layer 12 on the top surface of the heat exchange chamber; each heat exchange pipe in the heat exchange chamber 11 One end of the water pipe 13 is respectively connected with the water supply pipe 15, and the other end is respectively connected with the return water pipe 16, and the water supply pipe 15 and the return water pipe 16 respectively extend from the opposite side walls of the heat exchange chamber 11 to the side surface of the radiant plate 10 ; The bottom surface of the inner cavity in the heat exchange cavity 11 is located at the positions on both sides of each water exchange pipe 13 and is provided with drainage grooves 17 along the extending direction of the water exchange pipes. Condensed water guide grooves 18 are provided on one side of the water exchange pipe 13 along the extension direction of the water supply pipe and the return water pipe respectively; the drainage groove 17 is connected to the condensed water guide groove 18 and is guided It is connected to the condensed water drain pipe 19 located at the bottom of the side wall of the heat exchange chamber 11 and close to the position where the water supply pipe extends out of the radiant plate, and the drainage groove 17 and the condensed water guide groove 18 have a position where the return pipe extends out of the radiant plate The slope inclined towards the position of the condensate drain pipe, the slope value is preferably 1%~2%, so as to facilitate the flow of condensate water to the condensate drain pipe and discharge to the outside of the radiant plate; the heat exchange chamber is close to the return pipe An air inlet 1a of the heat exchange chamber is also provided on the side wall, and an air outlet 1b of the heat exchange chamber is also provided on the side wall near the water inlet pipe. In the radiant plate of the active radiant plate heat exchange system of the utility model, the water is supplied by the water supply pipe and flows through the heat exchange water pipe paved on the bottom surface of the inner cavity of the heat exchange chamber, so that the radiation surface on the ground of the heat exchange chamber forms a heating/ Cooling radiation, and then the water flows out from the return pipe; during this process, the airflow entering the return air passage also enters the heat exchange cavity of the radiant plate from the air inlet of the heat exchange cavity of the radiant plate, flows through the ventilation gap, and flows from the heat exchanger of the radiant plate The air outlet of the hot chamber flows out to the air outlet pipe. The ventilation gap between the heat exchange water pipe in the heat exchange chamber of the radiant plate and the insulation material layer on the top surface of the heat exchange chamber is equivalent to a heat exchange space, and the air flows in this ventilation gap. It conducts convective heat exchange with the heat exchange pipe, and then flows out to the air outlet pipe to be sent to the room, thereby increasing the heat exchange capacity and heat exchange efficiency of the radiant plate; the reason why the air inlet of the heat exchange chamber is set near the return chamber On the side wall of the water pipe side, the air outlet of the heat exchange chamber is arranged on the side wall of the heat exchange chamber close to the water inlet pipe. The direction of the water flow is opposite, forming a countercurrent convective heat exchange, so as to increase the efficiency of convective heat exchange in the radiant plate as much as possible; at the same time, the bottom surface of the inner cavity in the radiant plate heat exchange cavity is also provided with interconnected drainage grooves and condensation The water guide groove is connected to the condensate drain pipe by the guide groove of the condensed water guide, so that the condensed water generated by the condensation of the water supply pipe, the return pipe and the heat exchange pipe during the heat exchange can enter the drain groove and the condensed water guide The condensed water is diverted to the condensed water drain pipe for discharge with the help of the drainage groove and the slope of the condensed water guide groove, so as to solve the problem of condensation on the radiant plate, and in the cooling process, it flows through the radiant plate through the return air path The convective air in the heat exchange chamber exchanges heat with the heat exchange pipe to produce water vapor condensation, which reduces the moisture content of the air sent into the room from the air outlet pipe, thereby helping to eliminate the indoor humidity load.
作为优选方案,辐射板中的换热水管采用中空的半圆柱筒状,且其半圆柱筒状的平直表面铺贴在换热腔体的内腔底面上。与常用的圆形水管相比较,半圆柱筒状的换热水管可增大水与辐射表面的接触面积,且省去了中间传热介质,更有利于水与辐射表面间的冷热量传递,传热效率更高。 As a preferred solution, the heat exchange pipes in the radiant plate are in the shape of a hollow semi-cylindrical tube, and the flat surface of the semi-cylindrical tube is laid on the bottom surface of the inner cavity of the heat exchange cavity. Compared with the commonly used circular water pipes, the semi-cylindrical water exchange pipes can increase the contact area between the water and the radiating surface, and save the intermediate heat transfer medium, which is more conducive to the transfer of cold and heat between the water and the radiating surface , with higher heat transfer efficiency.
作为进一步的优选方案,辐射板的换热腔体内腔顶面的保温材料层上朝向换热水管的一面还涂覆有反射材料层。反射材料层所用的反射材料可以是阻隔性隔热涂料、热反射隔热纳米涂料、辐射隔热涂料铝箔等。该反射材料层用以减小水管向保温层方向辐射冷热量,同时衰减冷热量向保温层方向的传递,进一步帮助提高辐射板的辐射换热性能。 As a further preferred solution, the insulating material layer on the top surface of the inner cavity of the heat exchange cavity of the radiant plate is further coated with a reflective material layer on the side facing the heat exchange pipe.

在夏季,利用本实用新型的主动式辐射板换热系统对室内空气进行制冷降温和除湿处理的流程如下。向主动式辐射板换热系统中辐射板的供水管通入冷水,冷水流经辐射板的换热腔体内的各换热水管后,从回水管流出;同时启动回风通路中的风机,让主动式辐射板换热系统开始工作。此过程中,系统中与室内的换热分为三个部分,第一部分是辐射板外表面与室内空气的自然对流换热,第二部分是辐射板与室内空间的辐射换热,第三部分是室内外混合空气通过系统的回风通路并送入室内进行强迫对流换热,同时进行除湿。其中,第三部分换热处理的具体流程为:在风机的动力驱动下,室内回风与温度较高的室外新风分别从回风进气管和新风进气管被吸入进风管道内混合,形成混合空气,混合空气首先经过滤器对混合空气进行过滤,然后混合空气从辐射板的换热腔进风口进入辐射板的通风间隙内,并流向辐射板的换热腔出风口,由于换热腔进风口设置于换热腔体靠近回水管一侧,而换热腔出风口设置于换热腔体靠近进水管一侧,因此混合空气在辐射板通风间隙内的流动过程中,与换热水管内的冷水流呈逆流的对流换热状态,同时混合空气中的水蒸气与换热水管表面接触受冷而发生结露,达到对混合空气除湿的目的,冷却、除湿后的混合空气从辐射板的换热腔出风口流出后,经送风出气管送入室内,降低室内环境温度;而在辐射板的换热腔体内混合空气与换热水管进行对流换热的过程中,由于换热腔体内的内腔底面上位于每根换热水管两侧的位置处沿换热水管延伸方向设置有排水凹槽,内腔底面上位于供水管和回水管远离换热水管一侧的位置处分别沿供水管和回水管的延伸方向设置有冷凝水导向凹槽,且排水凹槽和冷凝水导向凹槽具有从回水管延伸出辐射板位置处向冷凝水排水管位置处倾斜的倾斜坡度,因此,换热水管对混合气体结露除湿所产生的冷凝水则从换热水管管壁下流至两侧的排水凹槽内,而供水管和回水管对混合气体结露除湿所产生的冷凝水则从供水管和回水管的管壁下流至一侧的冷凝水导向凹槽内,并由于排水凹槽和冷凝水导向凹槽相互贯通且具有倾斜坡度,这些冷凝水经排水凹槽和冷凝水导向凹槽被导流至冷凝水排水管,通过冷凝水管排出辐射板。 In summer, the process of cooling and dehumidifying the indoor air by using the active radiant plate heat exchange system of the present invention is as follows. Feed cold water into the water supply pipe of the radiant plate in the active radiant plate heat exchange system, and the cold water flows through the heat exchange pipes in the heat exchange chamber of the radiant plate, and then flows out from the return water pipe; at the same time, start the fan in the return air path, so that The active radiant heat exchange system starts to work. In this process, the heat exchange between the system and the room is divided into three parts, the first part is the natural convection heat exchange between the outer surface of the radiant panel and the indoor air, the second part is the radiation heat exchange between the radiant panel and the indoor space, and the third part is The indoor and outdoor mixed air passes through the return air path of the system and is sent into the room for forced convection heat exchange and dehumidification at the same time. Among them, the specific process of heat exchange treatment in the third part is: driven by the power of the fan, the indoor return air and the outdoor fresh air with a higher temperature are sucked into the air intake pipe from the return air intake pipe and the fresh air intake pipe respectively to form a mixed air. Air, the mixed air is first filtered by the filter, and then the mixed air enters the ventilation gap of the radiant plate from the air inlet of the heat exchange chamber of the radiant plate, and flows to the air outlet of the heat exchange chamber of the radiant plate, because the air inlet of the heat exchange chamber It is installed on the side of the heat exchange chamber near the return pipe, and the air outlet of the heat exchange chamber is arranged on the side of the heat exchange chamber near the water inlet pipe. Therefore, during the flow of the mixed air in the ventilation gap of the radiant plate, it will interact with the air in the heat exchange pipe. The cold water flow is in a countercurrent convective heat exchange state. At the same time, the water vapor in the mixed air is in contact with the surface of the heat exchange water pipe, and condensation occurs to achieve the purpose of dehumidifying the mixed air. The cooled and dehumidified mixed air is exchanged from the radiant plate After the air outlet of the hot chamber flows out, it is sent into the room through the air outlet pipe to reduce the indoor ambient temperature; and in the process of convective heat exchange between the air mixed in the heat exchange chamber of the radiant plate and the heat exchange pipe, due to the air in the heat exchange chamber The bottom surface of the inner cavity is located on both sides of each water exchange pipe, and drainage grooves are arranged along the extension direction of the water exchange pipe. Condensed water guide grooves are provided in the extension direction of the return pipe and the return pipe, and the drainage groove and the condensed water guide groove have an inclined slope from the position where the return pipe extends out of the radiant plate to the position of the condensed water drain pipe. Therefore, the heat exchange The condensed water produced by the water pipe for the condensation and dehumidification of the mixed gas flows down from the wall of the heat exchange pipe to the drainage grooves on both sides, while the condensed water produced by the water supply pipe and the return pipe for the dehumidification and dehumidification of the mixed gas flows from the water supply pipe. and the pipe wall of the return pipe flow down into the condensed water guide groove on one side, and because the drainage groove and the condensed water guide groove are connected to each other and have an inclined slope, the condensed water is discharged through the drain groove and the condensed water guide groove. Diverts to the condensate drain, through which it exits the radiant panel.

In this process, the heat exchange between the system and the room is divided into three parts, the first part is the natural convection heat exchange between the outer surface of the radiant panel and the indoor air, the second part is the radiation heat exchange between the radiant panel and the indoor space, and the third part is The indoor and outdoor mixed air passes through the return air path of the system and is sent into the room for forced convection heat exchange. Among them, the specific process of heat exchange treatment in the third part is: driven by the power of the fan, the indoor return air and the outdoor fresh air with a lower temperature are sucked into the air intake pipe from the return air intake pipe and the fresh air intake pipe respectively to form a mixed air. Air, the mixed air is first filtered by the filter, and then the mixed air enters the ventilation gap of the radiant plate from the air inlet of the heat exchange chamber of the radiant plate, and flows to the air outlet of the heat exchange chamber of the radiant plate, because the air inlet of the heat exchange chamber It is installed on the side of the heat exchange chamber near the return pipe, and the air outlet of the heat exchange chamber is arranged on the side of the heat exchange chamber near the water inlet pipe.
