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