FIELD: ventilation.
SUBSTANCE: device and method for air heating, air cooling and ventilation of rooms with the help of electric energy of centrifugal air pumps, an ammonia thermal pump, a controlled motor, heat exchangers, radiators, a controlled reduction valve, reversible electric motors, thermal controllers, pressure relays. In the mode of air heating and ventilation of rooms the ammonia thermal pump (ATP), while NH3 is boiling, it collects heat from air of rooms, and discharges air of rooms into atmosphere with temperature equal to atmosphere temperature. In the mode of air cooling and ventilation of rooms the ATP during NH3 collects heat from atmospheric air, and cooled air is discharged into rooms.
EFFECT: invention provides fresh air and permanent climate of rooms.
