摘要:
分析了多种测霜、除霜技术的优缺点,提出将光电转换测霜与类复叠循环除霜相结合可获得更有效的测霜、除霜效果. 具体内容包括:把现已成熟的光电原理运用到测霜装置上,用光电转换测霜,当光电信号的电压值达到除霜要求时,通过智能控制系统及时转换到除霜模式,高压压缩机继续制热,低压压缩机进行除霜循环,实现制热和除霜同时运行. 实验结果表明,测霜、除霜技术的结合既避免了误除霜事故的发生,也保证了压缩机的稳定运行,且缩短了除霜时间,改善了除霜效果.
Abstract:
The advantages and disadvantages of various frosting and defrosting techniques are analyzed. It is proposed to combine the photoelectric conversion frosting with the cascade-like cyclic defrosting to obtain more effective frosting and defrosting effects. The specific contents include: applying the now mature photoelectric principle to the frost measuring device. In using photoelectric conversion to measure frost,when the voltage value of the photoelectric signal reaches the defrosting requirement,the intelligent control system switches to the defrosting mode in time. The high pressure compressor continue to heat. A Low-pressure compressor performs defrost cycle. It realizes heating and defrosting at the same time. The test results show that the combination of frosting and defrosting technology avoids the occurrence of false defrosting accidents and ensures the running stability,a shortening defrosting time and an improved defrosting effect of the compressor.
