| description | The invention discloses a throttle valve control method of a low-temperature heat pump EVI water heater, which comprises the following steps of: after a unit is started, opening a throttle valve according to an initial opening degree and maintaining the initial opening degree for duration t1, then controlling the throttle valve to adjust the suction superheat degree, and correcting T for the first time and the second time in the adjusting process. The target superheat degree control mode is adopted for the throttling valve, then the throttling valve is corrected through the exhaust superheat degree, it is guaranteed that the throttling valve is not out of control during adjustment, the exhaust temperature is kept within a reasonable range value all the time, it is guaranteed that a unit can stably operate at different water temperatures and different environment temperatures, and the operation life of the unit is prolonged.
