AI Technical Summary
Existing inverter air conditioners are prone to frosting and icing in low-temperature environments, causing the cooling capacity to exceed demand. Furthermore, the control methods are not precise enough, affecting the stability and reliability of the air conditioner.
Multiple condensing branches are arranged in parallel, each with a valve. The valve opening is controlled by the frosting evaluation coefficient and the internal pipe temperature, and dynamically adjusted in conjunction with the external fan speed and compressor frequency to achieve independent control of the condenser flow rate and optimize the evaporation temperature and refrigerant flow rate.
It improves the cooling stability and reliability of the air conditioner in low-temperature environments, extends the operating time, reduces the number of times the anti-freeze compressor starts and stops, extends the system life, and improves the system's intelligent decision-making effect.
