AI Technical Summary

Technical Problem

The existing control method for air source heat pump units relies solely on high and low pressure values, resulting in poor reliability in harsh environments, inability to intervene in a timely and effective manner, and a tendency to cause serious malfunctions due to excessively high pressure ratios.

Method used

By calculating the pressure ratio and performing corresponding adjustments within different preset ranges based on the pressure ratio, including adjustments to the four-way valve, compressor, fan, and expansion valve, the pressure ratio is reduced to avoid high pressure ratio and pressure ratio imbalance.

Benefits of technology

It effectively reduces the pressure ratio, avoids serious malfunctions such as compressor burnout, pipe rupture and refrigerant leakage, and improves the operational reliability of air source heat pump units.
