Radiator for supercritical vapor compression type refrigerating cycle

摘要

In a radiator for a supercritical cycle, a refrigerant outlet is provided at a position higher than that of a refrigerant inlet in a vertical direction such that refrigerant flows from a lower side to an upper side in the radiator. Accordingly, even when temperature of cool air to pass through the lower side of the radiator is high, the temperature of refrigerant flowing in the lower side is so high that a sufficient difference in temperature between cool air and refrigerant can be provided. As a result, a cooling efficiency of refrigerant can be improved.
