Description
技术领域 technical field
本实用新型属于室内空调设施技术领域，具体涉及一种带有蓄冷装置的风机盘管与地板辐射联合空调系统。 The utility model belongs to the technical field of indoor air-conditioning facilities, in particular to a combined air-conditioning system with a fan coil unit and floor radiation with a cold storage device.
背景技术 Background technique
能源形势日趋严峻,节能减排已成为国家建设重要国策。在暖通空调领域,一些传统的空调方式由于其能耗太大或者节能优势不太明显将面临淘汰或者被要求进行节能改造。 The energy situation is becoming increasingly severe, and energy conservation and emission reduction have become an important national policy for national construction. In the field of HVAC, some traditional air-conditioning methods will face elimination or be required to carry out energy-saving transformation due to their high energy consumption or less obvious energy-saving advantages.
在辐射供冷方面,由于辐射供冷时使用的冷媒温度较高,使得蒸发冷却、深井水、地热(冷)等天然冷源的利用成为了可能。与天然冷源相结合的地板辐射供冷空调方式相比常规空调供冷能节能28%～40%，同时地板辐射供冷在舒适性方面的优势也小容小觑。人体三种传热方式进行散热的比例为对流散热26%,辐射散热50%,蒸发散热24%。由此可见辐射空调方式通过降低与围护结构的温度,使之与人体之间进行辐射换热。同时,由于辐射面及围护结构表面温度的降低使得它们与房间的对流换热也加强,从而进一步强化了辐射空调的供冷效果。这种空调方式完全避免了传统空调由于大量送风带来的“吹风感”、“空调病”和风机噪声。 In terms of radiant cooling, due to the high temperature of the refrigerant used in radiant cooling, it is possible to use natural cold sources such as evaporative cooling, deep well water, and geothermal (cold). The floor radiant cooling air-conditioning method combined with natural cold sources can save energy by 28% to 40% compared with conventional air-conditioning cooling. At the same time, the advantages of floor radiant cooling in terms of comfort can not be underestimated. The proportion of the three heat transfer methods of the human body is 26% for convection heat dissipation, 50% for radiation heat dissipation, and 24% for evaporative heat dissipation. It can be seen that the radiant air-conditioning method reduces the temperature of the enclosure structure and makes it radiate heat exchange with the human body. At the same time, due to the reduction of the surface temperature of the radiant surface and the enclosure structure, the convective heat transfer between them and the room is also strengthened, thereby further strengthening the cooling effect of the radiant air conditioner. This air-conditioning method completely avoids the "drying feeling", "air-conditioning disease" and fan noise caused by the large amount of air supplied by traditional air-conditioning.
辐射供冷空调突破了传统以对流为主要形式的空调方式,加大了人体与围护结构,围护结构与围护结构之间的辐射换热,并通过围护结构的蓄热作用达到建筑节能、移峰填谷、增强室内热舒适性的作用,对节能减排具有重大意义。 Radiant cooling air-conditioning breaks through the traditional air-conditioning method with convection as the main form, increases the radiation heat exchange between the human body and the enclosure structure, and the enclosure structure and the enclosure structure, and achieves the building temperature through the heat storage effect of the enclosure structure. Energy saving, shifting peaks and filling valleys, and enhancing indoor thermal comfort are of great significance to energy saving and emission reduction.
利用电网的峰谷电价差优势，空调主机利用夜间低谷电进行蓄冷，白天水池放冷而主机避峰运行的节能空调方式。水蓄冷技术优点为可采用常规冷水机组，系统简单高效，维护方便，降低初投资，可实现大温差送水和应急冷源，系统安全性高。 Taking advantage of the peak-to-valley power price difference of the power grid, the main unit of the air conditioner uses the low-valley power at night to store cold, and the pool is cooled during the day while the main unit operates off-peak. The advantages of water storage technology are that conventional chillers can be used. The system is simple and efficient, easy to maintain, reduces initial investment, can realize large temperature difference water delivery and emergency cold source, and has high system security.
尽管地板辐射供冷技术同样是以辐射方式为主传递热量，但由于存在一些局 Although the floor radiant cooling technology also transfers heat mainly by radiation, but due to some limitations
限性，给这种供冷方式的工程应用带来较多的限制条件。主要有地板凝露、供冷能力受限和过低的地板辐射面温度会引起人体的不舒适感的问题。 Limitations bring more restrictive conditions to the engineering application of this cooling method. The main problems are floor condensation, limited cooling capacity and low floor radiation surface temperature which will cause discomfort to the human body.
