摘要： A cooling and heating switching device for a variable refrigerant flow system capable of heat recovery, a variable refrigerant flow system, and a control method. Ends of multiple high-pressure branch pipes of the cooling and heating switching device are respectively connected to ends of multiple low-pressure branch pipes, so as to form multiple connection nodes. The multiple connection nodes are respectively connected to gas pipes of multiple indoor units. Further ends of the multiple high-pressure branch pipes are connected to a high-pressure gas pipe (3). Further ends of the multiple low-pressure branch pipes are connected to a low-pressure gas pipe (2). Ends of multiple branch liquid pipes are respectively connected to ends of multiple liquid sub-pipes, so as to form multiple connection nodes. The multiple connection nodes are respectively connected to liquid pipes of the multiple indoor units. Further ends of the multiple branch liquid pipes are connected to a main liquid pipe (1). Further ends of the multiple liquid sub-pipes are connected to a main pipe inlet of a subcooler (4). A throttling structure is provided on a connection pipe between a cooling branch pipe inlet (C) and a main pipe outlet (B). The cooling branch pipe outlet (B) is connected to the low-pressure gas pipe (2), thereby solving the issue of loud noise caused by a flowing refrigerant in an indoor unit of a variable refrigerant flow capable of heat recovery, and achieving a compact structure and low costs.

摘要： A water heating unit. In a water heating process, a flow ratio of hot water, entering a heating host (1), of a pressure bearing water tank (2) and an insulation water tank (3) is adjusted by means of a water mixing valve (9), so that adjusted water is heated by the heating host (1) once, and then directly enters the insulation water tank (3) to always guarantee that the using requirements of a user are met; moreover, in a dynamic adjusting process of the water mixing valve (9), water which flows out of a water outlet of the water heating host (1) but does not meet the temperature requirements can reflow to the pressure bearing water tank (2) by means of a valve (8) connected to the water outlet of the heating host (1), so that water which does not meet the temperature requirements is prevented from flowing into the insulation water tank (3).
