R422D制冷剂(MO29)是一种使用简单、ODP(臭氧消耗潜能)为零的HFC冷媒,具有与R22非常接近的制冷能力和效率,具有比R22更低的排气温度,在低温条件下,提供比R22高达8%制冷能力及高达14%效率;在中温条件且过冷度为10°F(6°C)时,MO29的制冷能力比R22低约5%,但效率与R22相当。

R422D可直接替换R22于中温和低温的直接膨胀(DX)式制冷设备,包括商业超级市场系统,及固定的直接膨胀(DX)式空调设备,中温及低温的商业、工业直接膨胀(DX)式制冷系统,如:餐饮冷藏、超市展示柜、食品储藏与加工、制冰机、家用、商用空调(AC)、直接膨胀(DX)式水冷机等。

R422D提供简单、高效、经济的直接替换,比R404A, R507,R407C具有更简单的替换。R422D制冷剂兼容传统的、新的润滑油,多数情况下,替换过程无需更换冷冻油;无需更换温度调节膨胀阀,可按照需要调节过热度。充注使用后,若发现系统内制冷剂容量不足,可以直接重新补足,无需排走全部已灌充的制冷剂。
