Problems solved by technology
[0003] 1. When there is a large difference in the tube side between each indoor unit and outdoor unit, because of the flow resistance in the pipeline, the evaporation pressure of the indoor units with different distances from the outdoor unit (taking refrigeration as an example) is different. If the heat is the same, the capacity of each evaporator will change differently. The indoor unit closer to the outdoor unit has a higher cooling capacity, and the farther the indoor unit is, the worse the cooling capacity is. This is not desired by users.
[0004] 2. When the refrigerant leaks in the system, the vaporization point moves forward, which cannot ensure the correct measurement of the saturation temperature, which reduces the flow rate and deteriorates the control performance

Description
technical field [0001] The invention belongs to an air conditioner, in particular to an air conditioner with one drag variable energy. Background technique [0002] Existing air conditioner sensors include thin tube temperature sensors, thick tube temperature sensors, return air temperature sensors, and some other saturation temperature sensors. The degree of superheat during cooling and the degree of subcooling during heating are roughly calculated based on the tube temperature measured by the thin tube temperature sensor, saturated temperature sensor, and thick tube temperature sensor. The flow rate of the refrigerant in each indoor unit is detected by the sensor to detect the degree of superheat of the heat exchanger and controlled by adjusting the throttling mechanism. The degree of superheat is detected by the saturation temperature sensor and the thick tube temperature sensor; The flow rate is detected by the sensor to detect the subcooling deg...
