Abstract

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.
