On the other hand, in step SB4, maximum exportable heat Q
hwhen being less than requirement heat Qreq, the maximum exportable load factor PL calculated in determination step SB3
hwhether be do not utilize heat energy passiveness to utilize more than load factor PLmin (step SB8).
Its result, maximum exportable load factor PL
