The installation contains channels 1 and. 2 for cold and warm humid air in which the heater-transfer device 3 is located, and the heat storage compartment 4 installed in the cold air duct 4. The additional heat exchanger 5 is placed in the warm moisture channel 2 before the heat-transmitting device 3. Both heat exchangers 4 and 5 are interconnected to form circulatory kosh-hurray. 6. The unit has filters 7, pallets 8 for condensate collection, section 9 of additional heating. In a number of cases, the installation can be equipped with an auxiliary circulation loop 10 with heat exchange sections 11 and 12, with section 11 installed in cold air channel 1 in front of the heat exchanger 4, and section 12 in warm humid air channel 2 between the heat-transmitting device 3 and the additional heat channel 5.

Circulation in the circuits can be carried out as in help of pumps, and at the expense of regional forces. The installation works as follows. The heat carrier circulating in circuit 6 and heated due to the removal of heat from the warm moist air (exhaust) enters the heat exchanger 4 and heats the cold air (external). Heated cold air then enters the heat transfer device 3, where it further increases its temperature. In section 9 of additional heating, cold air acquires the temperature from which it must flow to the consumer. Warm humid air (exhaust) enters an additional heat exchanger 5, where it is partially cooled by heating the coolant circulating in. circuit 6, the final warm air is cooled, the heat and moisture transfer device 3 passes. Similarly, the installation works on equipping it with auxiliary circulation circuit 10 with heat exchange sections 11 and 12.
