COLD STORAGE HEAT EXCHANGER

摘要

A cold storage heat exchanger that exchanges heat with air flowing therearound includes: a refrigerant passage through which refrigerant flows; and a cold storage body housing a cold storage medium that exchanges heat with refrigerant flowing through the refrigerant passage and stores an amount of heat from the refrigerant. The cold storage medium includes: a low carbon number paraffin comprising at least one of C12 paraffin and C13 paraffin; and a high carbon number paraffin comprising at least one of C15 paraffin and C16 paraffin. A concentration of the high carbon number paraffin in the cold storage medium is higher than 60 percent by weight and lower than 100 percent by weight. A concentration of the low carbon number paraffin in the cold storage medium is higher than 0 percent by weight and lower than 40 percent by weight.
