| 随着社会发展的不断进步，中央空调早已进入到普通百姓的家庭。然而很多消费者面对市场众多中央空调产品，不知道如何进行选择，在这里笔者根据自己从事中央空调销售的一些经验，发表一些看法，供大家参考。 With the continuous progress of social development, the central air conditioning has long entered the family of ordinary people. However, many consumers face the market many central air-conditioning products, I do not know how to choose, here, according to my own experience in sales of central air conditioning, I make some comments, for your reference. 家用中央空调已经全面进入了全直流变频时代。简单来说，就是中央空调的三个电动机：压缩机，室内风扇，室外风扇全部采用直流变频电动机。这种空调系统能做到最大限度的省电，静音，环保！ Household central air conditioning has fully entered the full DC frequency conversion era. Simply speaking, the central air-conditioning is the three motor: compressor, indoor fan, outdoor fan all adopt DC frequency conversion motor. This air conditioning system can maximize the power, mute, environmental protection! 而对于中央空调的选购来说，以下“五要素”显得特别重要！ [绿色小树草地分割线] For the central air-conditioning purchase, the following "five elements" is particularly important! [green trees, grass, split lines] 一、压缩机 Compressor 能够决定中央空调性能的两大核心部件是压缩机和变频器，他们分别是空调机的“心脏”和“大脑”！各品牌在是压缩机和变频器使用时区别在于会采用进口或国产品牌，这就导致了产品性能上的差异。 The two core components that can determine the performance of a central air conditioner are compressors and frequency converters. They are the heart of the air conditioner and the brain"! Each brand in the compressor and inverter use, the difference is that it will use imported or domestic brands, which led to differences in product performance. 然而，变频器安装在空调机的内部，拆卸较为复杂，作为消费者很难通过打开室外机外壳找到，更难以识别。因此为了简单说明，本文仅就压缩机进行展开分析。 However, the frequency converter is installed in the interior of the air conditioner, and the disassembly is more complicated. As a consumer, it is difficult to find out by opening the shell of an outdoor machine, which is more difficult to identify. Therefore, for the sake of simple explanation, the compressor expansion analysis is carried out only in this paper. 中央空调使用的压缩机发展经历了活塞式、单转子，双转子，涡旋式四个阶段。在这四种压缩机中活塞式和单转子压缩机在成本上价格较低，当然质量和性能也相对较差，现在已经很少用在家用中央空调中使用。 The compressor used in central air conditioning has gone through four stages: piston type, single rotor, double rotor, and vortex. In these four compressors, piston and single rotor compressors cost less, of course, quality and performance is relatively poor, and now rarely used in household central air-conditioning. 现在的家用中央空调所用压缩机主流是双转子和涡旋式压缩机。在这两种压缩机所对应的机器，其适用范围也有所区别。 The main compressor used in domestic central air conditioners are dual rotors and scroll compressors. In the two compressors corresponding to the machine, its scope is also different. 一般来说，建筑面积在130平米以下的家庭建议选用双转子压缩机，建筑面积在130平米以上的家庭建议选用涡旋压缩机压缩机，这是根据压缩机效率曲线图进行的判断。 Generally speaking, in the construction area of 130 square meters of the family suggested the use of double rotor compressor, the construction area of 130 square meters in the family suggested the use of scroll compressor compressor, which is based on the compressor efficiency curves are judged. 相对国产压缩机，发达国家本土生产的压缩机的质量和性能相来说还是优势较大，这些压缩机向全球同步发售，属于国际顶尖技术水平（压缩机生产工艺牵扯国家技术安全，保密性较强，外国最先进的压缩机都在本国本土生产！），当然价格上也就高了许多。 The relative domestic compressor, the quality and performance of the developed countries local production of the compressor is still great advantages of phase, the compressor to the global simultaneous release, which belongs to the international top level technology (compressor production process involves the national technology security, strong confidentiality, compressor the most advanced foreign production in native!) Of course, the price is much higher. 而在发展中国家生产出来的压缩机，从技术上来说相对要低一些，但是价格上相对就要便宜一些。 In developing countries, compressors are technically less expensive, but cheaper in price. 将空调室外机前面板打开，就能看到压缩机的铭牌。我们可以从压缩机的铭牌上看出来这台压缩机生产地，下面部分图片为例进行说明。 Open the front panel of the air conditioner outdoor unit and you can see the nameplate of the compressor. We can see from the nameplate of the compressor the place where the compressor is produced, and the pictures below are illustrated by examples. 二、二级过冷与气液喷（增）焓 Two, two stage supercooling and gas-liquid injection (increase) enthalpy 要想达到更适宜的温度，仅仅选择好压缩机是不够的。 It is not enough to choose a good compressor in order to achieve a better temperature. 1、考虑较强的制冷效果，特别是当空调机管路设计比较长（特别是大户型、别墅用户），那么制冷系统当中的二级过冷设计，就显得比较重要。 1, consider the strong cooling effect, especially when the air conditioning pipeline design is relatively long (especially the big family, villa users), then the refrigeration system in the two stage of supercooling design is more important. 二级过冷的原理是使用二级过冷管组对液态过冷制冷剂进行再次降温，现在市面上的有些品牌二级过冷后能够达到惊人的30℃。 The principle of two stage supercooling is to use the two stage supercooling tube set to cool the liquid supercooling refrigerant again. Now some of the two brands on the market can reach an alarming 30 DEG after supercooling. 行业不同机型在15-30℃不等，可以说这个技术的差异还是很大的。 Different types of industry at 15-30 degrees, you can say that the difference between this technology is still great. 2、如果要考虑超强的制热能力，就要选择带有气液喷（增）焓性能的中央空调系统（压缩机用气液喷焓压缩机）。 2, if you want to consider the super heating capacity, it is necessary to choose a gas jet (increase) enthalpy performance of the central air-conditioning system (compressor with liquid vapor enthalpy compressor). 这类机组甚至可以在零下20度左右能正常工作（甚至制热能力不衰减），超低温环境下，保持室温处于均衡的状态。 Such units can even work at about 20 degrees Celsius (or even heat capacity is not attenuated), ultra-low temperature environment, to maintain a room at a balanced state. 当然，带有上述两种技术特点的空调机相对价格也是偏高的。 Of course, with the above two technical characteristics of air conditioners, relative prices are also high. 三、主要零部件 Three, the main components 考虑到中央空调的设计寿命是二十年，购买时可选择知名度高中央空调品牌。这些品牌产品使用的零部件会具有更高的进口零部件比率。 Taking into account the central air-conditioning design life is twenty years, when buying, you can choose well-known high central air-conditioning brand. The components used by these brands will have higher import component ratios. 真正顶尖的中央空调品牌厂家应该有很强的“自主生产核心部件”的能力，能做到原厂部件专供。 The real top central air-conditioning brand manufacturers should have a strong "self production of core components," the ability to achieve the original parts for. 除压缩机和变频器外，其他主要零部件包括：主控板、变频基板、四通阀、电子膨胀阀、压力传感器、外机电机等等。 In addition to compressor and inverter, other main components include: main control board, frequency conversion base plate, four way valve, electronic expansion valve, pressure sensor, external motor and so on. 另外，高端产品的零部件的产地来源于发达国家生产基地（当然现在大多部件一般都是外企在中国或东南亚设厂），这类品牌相对来说机组的故障率极低，产品使用年限会更久。 In addition, the origin of high-end products in parts of the production base in the developed countries (though most parts are usually foreign companies to set up factories in Chinese or Southeast Asia), failure of this kind of brand is relatively the unit rate is extremely low, product life will be longer. 四、购买渠道 Four, purchasing channels 在各大城市的大卖场、品牌旗舰店、一级经销商选购中央空调。 In major cities hypermarkets, brand flagship store, a distributor to buy central air-conditioning. 因为一旦出现质量问题，大卖场（旗舰店）的服务响应会比较快，厂方对于售后服务也会更加重视（经销商的话语权决定空调品牌厂家的支持力度！）。 Because once the quality problems, large stores (flagship store) the service response will be faster, the service will also pay more attention to customer service (dealers the right to decide the air-conditioning brand manufacturers support!). 这种大卖场的口碑还是不错的，他们为了自身的品牌效应还是会为大家提供一些增值服务的便利。因提货渠道畅通，相对价格有优势，安装保障也会更有利，很多情况下省下了消费者的麻烦。 This big store reputation is still good, they for their own brand effect, or will provide you with value-added services to facilitate. Due to the smooth delivery channels, the relative price advantage, installation guarantee will be more profitable, in many cases save the trouble of consumers. 五、重视安装 Five, attach importance to installation “三分质量，七分安装”。中央空调经常出现安装好后不能正常使用的情况，多数问题是出在施工队安装不规范、责任心不强而造成的。 "Three points quality, seven points installation."". Central air conditioning often appears after installation can not be used normally, most of the problems are caused by the nonstandard installation of the construction team and the lack of sense of responsibility. 建议消费者尽可能选择具有安装资质的安装单位 Recommend that consumers choose the installation of qualified installation units as much as possible |
