随着冰柜市场的扩展,市场普遍反映出两大问题:一是低电压启动性能差。由于我国地域辽阔,电力紧张,地区差别大,特别是农村电网电压不稳定及电压偏低,压缩机启动性能虽符合国标GB 9098—88的要求,但在高温及低压下不能很好地解决启动问题。二是高温运行可靠性差。由于冰柜大多作为室外经营性使用,环境比较恶劣,户外最高温度可达55℃,使压缩机气阀出现早期结碳,排气量差,严重影响了冰柜的正常使用。根据这一情况,我厂结合我国国情,采用国际标准组织设计生产新一代QD52A压缩机,并制定了高于国标及日本松下压缩机标准要求的内控标准,同时增加了
With the expansion of the freezer market, the market generally reflects two major problems: First, low-voltage startup performance is poor. Due to China’s vast territory, power shortage, large regional differences, especially in rural power grid voltage instability and low voltage, although the compressor start-up performance in line with national standard GB 9098-88 requirements, but under high temperature and low pressure can not be a good solution to start problem. Second, the reliability of high temperature operation is poor. As most of the freezers are used for outdoor operation, the environment is rather harsh, the outdoor maximum temperature can reach 55 ° C, causing the compressor valve to have early knot carbon and poor exhaust volume, seriously affecting the normal use of freezers. According to this situation, I plant with China’s national conditions, the use of International Organization for Standardization design and production of a new generation of QD52A compressor, and developed higher than the national standard and Japan’s Matsushita Compressor standard requirements of internal control, while increasing
