AI Technical Summary
In multi-split air conditioning systems, the high pressure loss of the gas-liquid separator leads to increased refrigerant flow resistance and energy loss. Furthermore, the inconsistent compressor operating conditions during the transition phase result in uneven refrigerant distribution, affecting system energy consumption and efficiency.
The first and second gas-liquid separators are connected by a gas connecting pipe, and combined with auxiliary throttling elements and oil return regulating elements, the auxiliary throttling and oil return regulating are adjusted according to the compressor exhaust superheat and operating frequency to optimize gas-liquid separation and oil-gas management, and reduce pressure loss and oil content correction coefficient.
It achieves optimal performance of the air conditioning system under different transitional operating conditions, reduces pressure loss and energy consumption, and improves cooling efficiency and system stability.
