  • Control Of Temperature (AREA)

Abstract

PURPOSE: To make it possible to control a set temperature over a broad variable range with high precision by controlling the temperature of a refrigerant by another refrigerant by stages.
CONSTITUTION: A temperature is controlled by heating part 1 and 1stW3rd cooling parts 2W4. Refrigerant A in tank 22, held below set temperature T0 in thermostatic oven 5 by cooling (31) and heating (25), is sent to heat exchanger 21 by pump 23 to cool the temperature in thermostatic oven 5 and the calorific power of heater 25 is controlled (26 and 29) to maintain a constant difference from T0. Further, refrigerant B in tank 32, held below the temperature of A by cooling (41) and heating (35), cools (31 and 33) A. Then, refrigerant C in cooling part 4 is circulated to hold A and B with a fixed difference in temperature. Namely, B is controlled (4 and 35) to a temperature where hunting is large (curve c), but A is to that where hunting is a little (curve b), so that the internal temperature of the thermostatic oven will be controlled to a temperature where hunting is a little (curve a). Here, increasing refrigerants in kind improves precision.
