Abstract
In an internal heat exchanger, when a corresponding diameter of a high pressure passageis Ψh, a passage length Lh of the high pressure passage () is so set as to satisfy the relation 9.16/{LN(4.5+1.03)}<Lh<46/{LN(4.5+1.03)}, and when a corresponding diameter of a low pressure passageis Ψl, a passage length Ll of the low pressure passageis so set as to satisfy the relation 9.16/{LN(0.56×6+1.02)}<Ll<46/{LN(0.56×6+1.02)}, a passage sectional area Ah of the high pressure passageis so set as to satisfy the relation 100×(0.25×Ψh)≧Ah≧100×(500×Ψh), and a passage sectional area Al of the low pressure passageis so set as to satisfy the relation 1.65/Ψl<Al<626/Ψl.
