TEMPERATURE CONTROLLER Russian patent published in 1995 - IPC

FIELD: automatic control technique. SUBSTANCE: controller includes a setter and a pickup of a room temperature, analog-to-digital converter, three reversing counters, an OR-gate, a thyristor-type actuating member, a heater, a setter and a pickup of an air flow, a microprogram control device, a controllable frequency divider, a register, a temperature indicator, two digital-to-analog converters, a binary counter with preset registration, a timer. EFFECT: enlarged functional possibilities of the controller due to automatic control of upper and lower limits of temperature range of an in-flow ventilation system, enhanced reliability, enhanced dynamic of transient heat processes. 2 cl, 4 dwg
