Shunt valve setting method of refrigerant circulation system, generator and refrigerant circulation system

The invention discloses a shunt valve setting method of a refrigerant circulation system, a generator and the refrigerant circulation system. The method comprises the steps that a refrigerant circulation system is controlled to operate in a floor heating mode; sequentially controlling each shunt valve to switch the opening and closing states, and detecting the temperature change in the process of switching the opening and closing states of each shunt valve; and the binding relation between each shunt valve and the indoor unit is determined according to the temperature change. According to the method and the device, when the refrigerant circulating system operates in the floor heating mode, the shunt valves of all the rooms are independently opened/closed, the indoor units corresponding to the shunt valves are automatically recognized according to the temperature changes detected by the indoor units, and then the shunt valves and the indoor units are bound. Automatic and accurate binding of the air conditioner
