DEVICE FOR OBJECT THERMOSTATIC CONTROL Russian patent published in 2018 - IPC F26B23/02 F26B21/04 F23C9/00 

FIELD: transportation.

SUBSTANCE: device for object thermostatic control, especially for drying automotive bodies with an applied coating, comprises a thermostatic tunnel (14) which is located in the housing (12) and at least one tunnel section (T), which includes at least one air outlet (30) and at least one air inlet (42), wherein a heating unit (20) relates to the tunnel section (T), in which hot primary gas is produced by a burner assembly (44), the hot primary gas is directed to a heat exchanger (38) of the heating unit (20), in which the tunnel air from the mentioned at least one air outlet (30) is heated only by the hot primary gas, which is repeatedly supplied to the tunnel section (T) as a circulating air flow in a circulation mode through at least one air inlet (42). A burner supply device (40, 46) is provided, by means of which the exhaust air from the tunnel section (T) is supplied to the burner assembly (44) of the heating unit (20) as the air flow for combustion to create the primary gas for the burner assembly (44). The heating unit (20) comprises a dispenser (40) using which the tunnel air from the tunnel section (T) is divided into the circulating air flow and the combustion air flow, wherein the dispenser (40) is located downstream of the heat exchanger (38), so that the tunnel air heated there is divided into the circulating air flow and the combustion air flow.

EFFECT: decreased rato of exhaust gases released into the atmosphere via the roof.
