Abstract

PURPOSE: To minimize inside temperature changes in such a way that opening and closing temperature difference of a thermocontrol switch is set to a little amount, an evaporating pressure regulating valve is installed at the downstream of an evaporator in cooling chilling cycle, according as the temperature in the chamber is dropping, the valve is throttled.
CONSTITUTION: A regulating valve 15 is installed in refrigerating cycle C, which is constituted in such a way that it is regulated by a controller CO composed of a bridge circuit B comprising a thermistor 21, 2 pieces of resistors R, a variable resistror VR. Thus, cooling air flows through the inside of the chamber, a switch opens with drop of temperature, a compressore is brought to a standstill. SW1 is closed with rise in temperature. If temperature difference between make and break is set within a range of 1.5W2°C, temperature difference of a goods is made to be under 1°C. Besides, according to temperature changes in the cham ber, the bridge circuit makes a working means 22 to move a rod 15b, which expands a gap between a contact surface 15f of the regulating valve 15 and a valve seat 15g, or contracts it, the temperature in the chamber is conrolled with increase and decrease in refrigerant amount, to maintain cold temperature which is set thereby.
