Description
技术领域 technical field
本发明涉及一种机房空调节能控制系统。 The invention relates to an energy-saving control system for an air conditioner in a computer room.
背景技术 Background technique
空调是日常生活和工业生产中主要降温的设备，而空调又是高耗能电器。目前，大多数的铁路信号机房一般采用空调降温的方法来保证设备的正常运行，即使室外温度较低时，机房空调也处于运行状态，耗电量巨大。根据调查广西的年平均气温25℃，在最为炎热的夏季平均气温为29℃，夜间气温大多数低于23℃，假如充分利用室外夜间温度低的有利条件，进行室内外空气交换，就能减少机房空调的运行时间，降低机房空调能源的消耗，实现机房节能运行。 Air conditioners are the main cooling equipment in daily life and industrial production, and air conditioners are high energy-consuming electrical appliances. At present, most of the railway signal rooms generally use air conditioning to cool down the temperature to ensure the normal operation of the equipment. Even when the outdoor temperature is low, the air conditioner in the machine room is still running, which consumes a lot of power. According to the survey, the annual average temperature in Guangxi is 25°C. In the hottest summer, the average temperature is 29°C, and most of the nighttime temperatures are lower than 23°C. The running time of the air conditioner in the computer room can reduce the energy consumption of the air conditioner in the computer room and realize the energy-saving operation of the computer room.
铁路信号机房常年至少一台空调制冷：由于铁路信号机房的设备工作在一个相对密闭的环境，大量设备在工作时大量散热。而无法与室外空气进行热交换，该发热量只能依靠铁路信号机房空调制冷来进行温度控制。在不同季节，尽管机房室内外温差较大，比如冬季室内外温差可达30℃以上，但是由于铁路信号机房是密闭的，室内温度仍然很高，因此空调仍处于制冷状态，并严重损耗了电能。铁路信号机房设备运行不间断性要求空调能够长期可靠不间断地工作，备机切换，多机能够协调工作。但是现行铁路信号机房的空调不具备这方面的功能，如：对于二台空调工作的机房，据统计，需同时运行二台空调的时间在一年当中有四个月左右，而运行一台空调的时间约为六个月。根据有关资料统计分析，平均每个铁路信号机房空调的电费支出约占整个机房电费支出的52%左右，空调成为机房中的主要用电设备。不同地区空调用电所占总用电量比例有一些差异，但差异不会太大。据统计：目前二台3P 空调工作的机房，正常使用时全年空调用电费用大约为18000 元左右，目前因普遍采用了非工业用的民用空调，其工作效率较工业空调要低20%左右，因此，实际电费支出会更大。由此可见，目前铁路信号机房普遍采用一台以上空调工作，用电量大，由于普遍未采用有效的管理手段，用电浪费大，空调维护成本高。节电并采用有效的空气温度调节手段可以由此带来很大的效益。 The railway signal room has at least one air conditioner for cooling all the year round: Since the equipment in the railway signal room works in a relatively closed environment, a large number of equipment dissipates heat during work. However, heat exchange with the outdoor air cannot be performed, and the heat generation can only be controlled by air conditioning and refrigeration in the railway signal room. In different seasons, although the indoor and outdoor temperature difference in the computer room is large, for example, the indoor and outdoor temperature difference can reach more than 30°C in winter, but because the railway signal computer room is airtight, the indoor temperature is still high, so the air conditioner is still in a cooling state and seriously consumes power. . The uninterrupted operation of the equipment in the railway signal room requires that the air conditioner can work reliably and uninterruptedly for a long time, the standby machine can be switched, and multiple machines can work in coordination. However, the air conditioners in the current railway signal room do not have this function. For example, for a machine room where two air conditioners are working, according to statistics, the time required to run two air conditioners at the same time is about four months in a year, while running one air conditioner for about six months. According to the statistical analysis of relevant data, the average electricity expense of each railway signal room air conditioner accounts for about 52% of the electricity expense of the entire computer room, and the air conditioner has become the main electrical equipment in the computer room. There are some differences in the proportion of air-conditioning electricity consumption in the total electricity consumption in different regions, but the difference will not be too large. According to statistics: at present, in the computer room where two 3P air conditioners work, the annual electricity consumption of the air conditioner is about 18,000 yuan during normal use. At present, non-industrial civil air conditioners are generally used, and their working efficiency is about 20% lower than that of industrial air conditioners. , so the actual electricity bill will be larger. It can be seen that at present, more than one air conditioner is generally used in the railway signal room, which consumes a lot of electricity. Due to the lack of effective management methods, the waste of electricity is large, and the maintenance cost of the air conditioner is high. Saving electricity and employing effective means of air temperature regulation can thus bring great benefits.
