Circulation system used in air conditioner, has bypass arranged to branch off in flow direction in front of hydraulic switch of return path and downstream of hydraulic switch via three-way valve opens into return path

摘要

The circulation system has bypass, which branches off in the flow direction in front of the hydraulic switch from the flow path (21) and downstream of the hydraulic switch opens via a three-way valve into the flow. The return path (22) of the load (8) is connected with the hydraulic switch. The bypass is arranged to branch off in the flow direction in front of the hydraulic switch of the return path and downstream of the hydraulic switch via a three-way valve opens into the return path.
