Changes in temperature type air conditioning system and single cold mould air conditioning system

The utility model discloses a changes in temperature type air conditioning system and single cold mould air conditioning system. The changes in temperature type air conditioning system include: enhanced vapor injection compressor, indoor outdoor heat exchanger, two throttling arrangement, flash vessel and automatically controlled heat exchangers. The flash vessel includes three interface, first interface and indoor heat exchanger intercommunication, and the second interface links to each other with the compressor air jet with outdoor heat exchanger intercommunication, third interface. A throttling arrangement establishes ties between outdoor heat exchanger and flash vessel, and the 2nd throttling arrangement establishes ties between indoor heat exchanger and flash vessel, and automatically controlled heat exchanger is established ties between two throttling arrangement. According to the utility model discloses an air conditioning system through setting up flash vessel and enhanced vapor injection compressor, has improved the complete machine performance. The electric control element radiating effect is good, normal work in the time of can guaranteeing electric control element high temperature. Establish automatically controlled heat exchanger between two throttling arrangement, guaranteed that the refrigerant temperature of the automatically controlled heat exchanger of flowing through is suitable, just also guaranteed electric control element's life and safe in utilization.
