LED高温老化房是LED行业应用最广泛的检测设备之一，市场需求量越来越大。LED高温老化房冷媒的选择是一个复杂的技术和经济问题,许多因素需要被考虑：第一，LED高温老化房冷媒考虑环保要求：冷媒必须选择符合国家环保法规冷媒。LED高温老化房是有限的生产高、低温度热室厂家里使用R404A,R23(环保)冷媒的厂家。
LED high temperature aging room is one of the most widely used detection equipment in the LED industry, and the market demand is increasing. The choice of refrigerant for high temperature aging room of LED is a complex technical and economic problem. Many factors need to be considered. First, the refrigerant for high temperature aging room of LED should consider environmental protection requirements: refrigerant must be selected in accordance with national environmental protection regulations. LED high temperature aging room is a limited manufacturer of high and low temperature heat chamber manufacturers using R404A, R23 (environmental protection) refrigerant manufacturers. 第二,LED高温老化房应考虑冷媒的性质
Secondly, the nature of refrigerant should be considered in the high temperature aging room of LED.
根据冷媒热力性质、物理性质和化学性质,选择那些无毒、无爆炸性,不可燃冷媒;可选的冷媒应该良好的传热、阻力和冷却系统材料兼容性。所以对于一些国家的产业,必须无毒、无污染、安全冷媒冷却效果好。
According to the thermodynamic, physical and chemical properties of refrigerants, those non-toxic, non-explosive and non-combustible refrigerants should be selected; the selected refrigerants should have good heat transfer, resistance and material compatibility of cooling system. Therefore, for some countries, the industry must be non-toxic, pollution-free, safe refrigerant cooling effect is good.
第三,考虑LED高温老化房冷却温度的要求
Third, consider the cooling temperature requirement of LED high temperature aging room
根据冷媒温度和冷却条件下,选择高温(低压)、温度(介质压力)和温度(高压)冷媒。一般选择标准冷媒蒸发温度低于10℃冷却温度。选择制冷设备应考虑冷媒冷却条件、使用环境。运行的压缩机冷凝压力不应超过安全使用指定的值。做高低温热室温度零下60℃的测试,因此冷媒的要求。和社会汽车空调冷媒不同,汽车冷媒气车外可以做冷却介质,影响空气温度、风速、太阳辐射、热辐射和其他因素都频繁改变操作条件决定,它只能使用高温(低压)冷媒,经过使用,现在大多用R134aR12。
High temperature (low pressure), temperature (medium pressure) and temperature (high pressure) refrigerants are selected according to refrigerant temperature and cooling conditions. Generally, the evaporation temperature of standard refrigerant is lower than 10 C. The selection of refrigeration equipment should consider refrigerant cooling conditions and operating environment. The condensation pressure of the compressor in operation shall not exceed the specified value for safe use. The temperature of the high and low temperature hot room is tested at 60 below zero, so the refrigerant is required. Unlike the refrigerant of social automobile air conditioning, the outside of automobile refrigerant can be used as cooling medium, which affects the air temperature, wind speed, solar radiation, thermal radiation and other factors. It can only use high temperature (low pressure) refrigerant. After use, most of them use R134aR12 now.
第四,压缩机的类型影响冷媒的选择
Fourth, the type of compressor affects the choice of refrigerant
不同的制冷压缩机工作原理不同。容积式压缩机冷媒蒸气通过减少压力的体积增加,一般用于冷却能力每单位体积的冷媒,如R134a,R22等等。许多不同类型的冷媒,随着科学和技术的进步，新兴新型冷媒的制冷装置适用于不同。
Different refrigeration compressors work differently. Volumetric compressor refrigerant vapor increases by reducing the volume of pressure, generally used for cooling capacity per unit volume of refrigerant, such as R134a, R22 and so on. Many different types of refrigerants, with the progress of science and technology, new refrigerant refrigeration devices are suitable for different types.
