R32制冷剂无色、无味,并具有轻微燃烧特性(A2级别),其沸点在常压下为-51.6ºC。 在空气中,其燃烧极限范围为14%~31%(体积比)。 常温条件下,HFC-32结构稳定,不易分解。 然而,当遇到明火或高温时,它会分解为HF、碳酰氟等物质,其引燃温度为647.8℃。 因此,使用R32制冷剂的设备必须进行抽真空操作,并严格禁止明火接触。 此外,R32制冷剂具有溶于油、难溶于水的特性。 其破坏臭氧潜能值ODP为0,全球变暖系数值GWP为670。 相比R22,R32的 …

空调的三个压力指什么?R22、R32、R410A空调分别是多少?
2019年8月12日 · 三个压力是制冷剂R22在空调管路中循环在不同位置所对应的压力,由于R22是在气液之间循环变化的,伴随着吸热和放热,所以外界环境的温度对其有明显的影响。 一般情况下,环境温度高,压力值变大。 环境温度低,压力值变小。 平衡压力:是指压缩机不工作时,高低压平衡时的压力; 高压压力:是指排气压力或冷凝压力; 低压压力:是指吸气压力或蒸发压力。 三个压力的测量都是在室外机气阀的工艺口上,制冷运转时为低压压力,制热运转时为高压压力,不 …

R32 - DAIKIN Chem
R32 is a refrigerant that addresses a range of environmental and safety considerations: • Zero Ozone Depletion Potential (ODP) • Lower global Warming Potential (gWP) – about one third of R410a • R32 allows for reduced refrigerant charge, compact design and high energy efficiency
R-32 Refrigerant Pressure Chart - hvaclearningcampus.com
2024年10月29日 · R-32 is one of the more prominent refrigerants used today. Known for its low global warming potential (GWP) and high energy efficiency, R-32 is increasingly being adopted in HVAC in North America. A refrigerant pressure chart provides vital information about the relationship between the pressure and temperature of the refrigerant within a system.
R32 is a chlorine-free, ozone-safe fluorocarbon whose boiling point is -52°C. R32 is a component of R410a, a blend refrigerant widely used in developed coun-tries as a main alternative to HCfC-22, an ozone depleting refrigerant. But R410a has a high global Warming Potential (hereafter, gWP) of 2088, so a new refrigerant
