Abstract
A heat cycle system and a control method. The heat cycle system includes: driving devices, one or a plurality of outdoor units, and a plurality of indoor units, which are connected by pipelines; a bypass pipeline for the plurality of indoor units, a bypass valve being disposed in the bypass pipeline; a pressure sensor that senses a pressure difference ΔPacross the plurality of outdoor units; and a controller that is preset with a pressure difference set value ΔP, wherein the controller calculates a pressure offset parameter ΔP=ΔP−ΔPand adjusts an opening degree of the bypass valve based on the pressure offset parameter ΔP so that the pressure offset parameter ΔP approaches zero, and wherein the controller is preset with a first pressure offset threshold P, and the controller is configured such that closed indoor units enter a bypass mode one by one when ΔP>P, until ΔP≤P.
