Description
技术领域technical field
本发明属于暖通空调领域，具体是一种具有除湿功能的壁挂辐射板及使用该辐射板的辐射空调系统。The invention belongs to the field of HVAC, in particular to a wall-mounted radiant panel with dehumidification function and a radiant air-conditioning system using the radiant panel.
背景技术Background technique
近些年来，辐射空调系统作为一种舒适节能的新型空调系统，很好地与低能耗或绿色建筑结合，有着广泛的应用前景。辐射空调系统主要由辐射供冷末端、独立新风系统及冷热源组成。其中辐射供冷是基于大表面低温差换热原理，通过降低围护结构内表面中一个或多个表面的温度，形成冷辐射面，然后通过辐射面以辐射和对流的传热方式向室内供冷。相比传统风机盘管对流空调系统，辐射空调系统能够明显提高室内热环境均匀性及舒适度，并降低空调系统能耗，是解决南方供暖问题的最有效空调技术之一。In recent years, as a new type of comfortable and energy-saving air-conditioning system, radiant air-conditioning system is well combined with low energy consumption or green buildings, and has broad application prospects. The radiant air conditioning system is mainly composed of a radiant cooling terminal, an independent fresh air system and a cold and heat source. Among them, radiation cooling is based on the principle of large-surface low temperature difference heat transfer. By reducing the temperature of one or more surfaces in the inner surface of the enclosure structure, a cold radiation surface is formed, and then the radiation and convection heat transfer methods are used to supply heat to the room through the radiation surface. cold. Compared with the traditional fan coil convection air conditioning system, the radiant air conditioning system can significantly improve the uniformity and comfort of the indoor thermal environment, and reduce the energy consumption of the air conditioning system. It is one of the most effective air conditioning technologies to solve the heating problem in the south.
然而，当冷辐射面表面温度低于室内空气露点温度时，会产生结露，影响室内卫生条件。由于露点温度限制，冷辐射面表面温度不能太低，如此限制了辐射供冷的能力，因此辐射供冷末端需要与具有除湿功能的独立新风系统结合。此外，为了保证冷辐射面不结露，辐射空调房间一般严格要求用户不能随意开窗，如此不符合住宅用户的生活习惯，因此目前的辐射空调系统不适合应用于居住建筑。However, when the surface temperature of the cold radiating surface is lower than the dew point temperature of the indoor air, condensation will occur, which will affect the indoor hygienic conditions. Due to the dew point temperature limit, the surface temperature of the cold radiant surface cannot be too low, which limits the ability of radiant cooling. Therefore, the end of radiant cooling needs to be combined with an independent fresh air system with dehumidification function. In addition, in order to ensure that the cold radiation surface does not condense, radiant air-conditioning rooms generally strictly require users not to open windows at will, which does not meet the living habits of residential users, so the current radiant air-conditioning system is not suitable for residential buildings.

本发明采用上述具有除湿功能的壁挂辐射板的辐射空调系统包括压缩机，压缩机的气体出口连接四通换向阀的第一输入端管口，四通换向阀的第四输入输出端管口与设置有冷凝排水盘的室外翅片管换热器的一端管口连接，室外翅片管换热器的另一端管口经设置有毛细管的管路与室内辐射板换热器的一端管口连接，室内辐射板换热器的另一端管口连接四通换向阀的第二输入输出端管口，四通换向阀的第三输出端管口通过设置有气液分离器的管路与压缩机的气体入口连接。The radiant air-conditioning system using the above-mentioned wall-mounted radiant panel with dehumidification function in the present invention includes a compressor, the gas outlet of the compressor is connected to the first input port of the four-way reversing valve, and the fourth input and output port of the four-way reversing valve is The mouth is connected to one end of the outdoor finned tube heat exchanger with a condensate drain pan, and the other end of the outdoor finned tube heat exchanger is connected to one end of the indoor radiant plate heat exchanger through a pipeline with a capillary tube. The other end of the indoor radiant plate heat exchanger is connected to the second input and output port of the four-way reversing valve, and the third output port of the four-way reversing valve passes through the pipe provided with the gas-liquid separator. The circuit is connected with the gas inlet of the compressor.
所述的室外翅片管换热器的冷凝排水盘上设置有用于排水的小孔，且冷凝排水盘与室内辐射板换热器的冷凝接水盘相连通。The condensate drain pan of the outdoor finned tube heat exchanger is provided with small holes for drainage, and the condensate drain pan communicates with the condensate drain pan of the indoor radiant plate heat exchanger.
与现有技术相比，本发明提供的壁挂式辐射板通过将铜管紧贴外侧内壁，并在外壳外侧外表面设置疏水材料层，能够使在外壳表面换热时形成的结露聚集成水滴；通过在外壳底部设置冷凝接水盘，将疏水材料层上聚集的水滴收集在冷凝接水盘中，这样的结构有效解决了传统结构的结露问题，能大幅度地降低了空气湿度；并且通过设置保温材料层，有效的防止墙面结露现象的发生。该壁挂式辐射板结构简单、紧凑，使用及清洗方便。Compared with the prior art, the wall-mounted radiant panel provided by the present invention can make the condensation formed during heat exchange on the surface of the shell gather into water droplets by adhering the copper pipe to the outer inner wall and setting a layer of hydrophobic material on the outer surface of the outer shell ; By setting a condensation water tray at the bottom of the shell, the water droplets accumulated on the hydrophobic material layer are collected in the condensation water tray. This structure effectively solves the condensation problem of the traditional structure and can greatly reduce the air humidity; and By setting the insulation material layer, the occurrence of condensation on the wall can be effectively prevented. The wall-mounted radiant panel has a simple and compact structure, and is convenient to use and clean.
进一步地，由于管道外包裹有铝箔层能够均匀散发冷热量。Further, since the pipe is wrapped with an aluminum foil layer, cold and heat can be distributed evenly.
进一步地，由于管道为呈蛇形的铜管，能够增大散热面积。Further, since the pipe is a serpentine copper pipe, the heat dissipation area can be increased.
本发明提供的辐射空调系统，采用了具有除湿功能的壁挂辐射板做为室内辐射板换热器，运行时将压缩机产生的冷量传递到外壳前壁，使其表面温度低于室内空气露点温度，此时外壳前壁出现结露现象，由于在前壁外表面设置疏水材料层，并在外壳底部设置冷凝接水盘，使凝结的水被收集到冷凝接水盘中，彻底解决传统结构结露的问题。本发明的空调系统由于使用了具有除湿功能的壁挂辐射板，室内空气温度和相对湿度一般为26℃和50%，对应的室内空气露点温度为14.8℃，辐射板外壳表面的温度达到14℃即可使室内的水蒸气凝结成水达到除湿效果，同时根据铜管内侧与外壳表面之间的热阻，制冷剂温度可增大到12℃（蒸发温度），相比传统风机盘管对流空调系统能显著提高空调系统的蒸发温度和系统能效比。The radiant air-conditioning system provided by the present invention adopts the wall-mounted radiant plate with dehumidification function as the indoor radiant plate heat exchanger, and transfers the cold energy generated by the compressor to the front wall of the shell during operation, so that the surface temperature is lower than the dew point of the indoor air At this time, dew condensation occurs on the front wall of the housing. Since a hydrophobic material layer is set on the outer surface of the front wall, and a condensation water tray is installed at the bottom of the housing, the condensed water is collected into the condensation water tray, which completely solves the traditional structure. Condensation problem. Because the air-conditioning system of the present invention uses the wall-mounted radiant panel with dehumidification function, the indoor air temperature and relative humidity are generally 26°C and 50%, the corresponding indoor air dew point temperature is 14.8°C, and the temperature on the surface of the radiant panel shell reaches 14°C. The water vapor in the room can be condensed into water to achieve the dehumidification effect. At the same time, according to the thermal resistance between the inner side of the copper tube and the surface of the shell, the temperature of the refrigerant can be increased to 12°C (evaporation temperature), compared with the traditional fan coil convection air conditioning system It can significantly improve the evaporation temperature and system energy efficiency ratio of the air conditioning system.
进一步的，将收集的冷凝水通过管路送到冷凝水排水盘，冷凝水通过小孔以液滴形式流过室外换热器的表面，从而降低室外换热器的表面温度，并通过制冷剂流动降低室内换热器的表面温度而提高空调系统的制冷能力。Further, the collected condensed water is sent to the condensed water drain pan through the pipeline, and the condensed water flows through the surface of the outdoor heat exchanger in the form of droplets through small holes, thereby reducing the surface temperature of the outdoor heat exchanger and passing the refrigerant The flow lowers the surface temperature of the indoor heat exchanger and increases the cooling capacity of the air conditioning system.
