Title:
HIGH-TEMPERATURE AIR CONDITIONING UNIT
Document Type and Number:
WIPO Patent Application WO/2017/206631
Kind Code:
A1
Abstract:
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.
