(57) @ This invention refers to a system for postheating already dehumidified air which
uses a known normal refrigerating circuit (main circuit P), which is connected to
a secondary circuit (S) through at least one two-phase exchanger element (5), situated
downstream of the main circuit evaporator (15). The dehumidified air is thus heated
by a condenser-exchanger (2), placed in the secondary circuit. According to this invention
an economical and reliable postheating system is achieved. The heating capacity of
the postheating condenser-exchanger (2) is regulated by a new mechanical device (3,4),
which allows proportional regulation.
