一种高温空调机组
摘要：
本发明公开了一种高温空调机组，特别是一种高温制冷/热泵机组，通过对节流阀设置方式的改变，使得低压管路中冷媒的压力小于中压管路内冷媒的压力，保证了低压管路内用于冷却部件的冷媒是低压的，从而解决了现有技术中由于蒸发压力过高导致的变频器、电机、润滑油冷却不足或不可冷却的问题，且系统结构简单，运行可靠。作为优选，通过采用对冷凝器出口高温高压的液态冷媒进行二次节流的方式，获得低温低压冷媒，从而实现对变频器、电机、润滑油等进行冷却；同时，采用高温高压的液态冷媒驱动引射器，将冷却完变频器、电机、润滑油的低温低压冷媒吸入并使其回到中温中压的蒸发器。
摘要（英）：

Disclosed is a high-temperature air conditioning unit. By changing the arrangement mode of throttle valves (14, 15), the pressure of refrigerants inside a low-pressure pipeline is made to be smaller than the pressure of refrigerants inside a medium-pressure pipeline, thus ensuring that the refrigerants, used for cooling components, inside the low-pressure pipeline are low in pressure, thereby solving the problem in the prior art that a frequency converter, an electric motor and lubricating oil are not cooled sufficiently or cannot be cooled due to excessively high evaporation pressure.
