Beschreibung
Zusammenfassung:	The invention relates to a high heat unit, and a method, system and air condition for controlling the unit. According to the invention, a condensation side inlet and an evaporation side inlet of an intermediate heat exchanger are both connected with an indoor heat exchanger. A condensation outlet of the intermediate heat exchanger is connected with an outdoor heat exchanger. The evaporation side outlet of the intermediate exchanger is connected with a gas liquid separator. A pipeline connecting the evaporation side inlet of the intermediate heat exchanger with the indoor heat exchanger is provided with a third throttling device. A second throttling device is arranged on a pipeline connecting a condensation outlet of the intermediate exchanger and the outdoor heat exchanger. According to the invention, by adopting a method of heating low-pressure side cold medium by utilizing the intermediate heat exchanger and by controlling the opening degrees of the throttling devices based on a specific logic, the integral
