SUPPLY AIR CONDITIONER WITH NON-FLUID ROTARY HEATING Russian patent published in 2019 - IPC F24F5/00 

FIELD: ventilation and air conditioning.

SUBSTANCE: claimed solution relates to supply air conditioners for maintenance of public buildings during cold season. Supply air conditioner with non-liquid rotary heating, comprising inflatable chamber and main exhaust chamber, separated by horizontal intermediate partition with main and additional rotor channels and arrangement of main rotor channel of horizontal intermediate partition at inlet of outside air into air conditioner, an adsorption rotary regenerator with an inverter having oppositely directed lines of external air inflow and exhaust of air removed from the room, a rotor recuperator-heat exchanger with an inverter having a line of external air inflow. Adsorption rotary regenerator is built into additional rotor channel of horizontal intermediate partition of air conditioner, and rotary heat exchanger – into main rotor channel of horizontal intermediate partition. Besides, air conditioner comprises additional exhaust chamber arranged above horizontal intermediate partition with coverage of rotary heat exchanger. Air conditioner comprises recirculation channel of air withdrawn from room, connecting main exhaust chamber of air conditioner at its outlet with additional exhaust chamber at its inlet, providing passage of drawing line of air withdrawn from room through additional exhaust chamber of air conditioner with change of its direction from opposite directed line of external air inflow to unidirectional one. At that, rotary heat exchanger recovers heat of air removed from room of additional exhaust chamber of air conditioner and transfers this heat to fresh air.

EFFECT: obtaining zero power consumption for heating supply air in the air conditioner to final temperature t₃=20 °C, relative humidity ϕ₃=0,44 and moisture content d₃=6,5 g/kg at temperature of air removed from room at inlet to main exhaust chamber of conditioner t₄=23 °C, moisture content d₄=8,5 g/kg, when ambient air temperature changes in range t₁=(-30)÷10 °C, relative humidity ϕ₁=0,8 and moisture content in range d₁=0,19÷6,23 g/kg and improved energy efficiency of the air conditioner.
