Abstract

PURPOSE: To perform quick temperature control with a simple constitution, by controlling the operation of the switching valve provided in the flowing in and out path of the cooling tube for coolant flow with the control section and taking the sum of the voltage fed to the heater and that for switching valve control constant.
CONSTITUTION: The electromagnetic valve 58 switching water supply and the heater 55 are connected to the output of the control unit 59, and the thermister 57 is connected to the input. In taking the set temperature as 37°C, if the temperature for water of constant temperature vessel is increased not less than 37°C, the heater 55 is OFF, the electromagnetic valve 58 is open, and the system is at cooling state. Conversely, the temperature is 37°C or less, 55 is ON and the valve 58 is closed and the system is in heating state. Thus, the flow of coolant is stopped in heating the constant temperature vessel and inversely, in cooling, the coolant flows and the heater is not operated, allowing to efficient temperature control.
