AI Technical Summary
The cascade heat exchanger in binary refrigeration systems often experiences reduced heat exchange efficiency due to a large proportion of liquid refrigerant, which occurs when the evaporator load varies, leading to subcooling of the refrigerant and occupying a significant region in the heat exchanger.
A refrigeration cycle system with a first and second circuit, incorporating a controlling valve and subcooling heat exchanger, which adjusts the flow path to prevent excessive liquid refrigerant in the cascade heat exchanger by controlling the valve based on predetermined conditions, such as temperature and pressure differences, ensuring that the system addresses this by allowing the cascade heat exchanger to maintain optimal fluid refrigerant circulation and bypass circuits, thereby enhancing the cascade heat exchanger to maintain the cascade heat exchanger.
This system enhances heat exchange efficiency by preventing the accumulation of liquid refrigerant, thereby maintaining optimal operating conditions and improving the performance of the cascade heat exchanger.
