Title:
METHOD FOR PREVENTING FREEZING OF LIQUID
Document Type and Number:
Japanese Patent JPS58196845
Kind Code:
A
Abstract:

PURPOSE: To prevent the freezing of a liquid in low power consumption, by irradiating ultrasonic energy generated from the vibrator of an ultrasonic oscillator into the liquid.

CONSTITUTION: When the temp. of water in the container or the pipe of heat exchanger 1 is lowered to a predetermined value or less, an ultrasonic oscillator 9 is operated to vibrate a vibrator 8 which in turn irradiates ultrasonic energy into a liquid. By this method, the freezing of water in a water introducing tank 2 and water in a heat absorbing pipe 4 and a hot water discharge tank 3 connected to said water introducing tank 2 is prevented. As mentioned above, the freezing of a liquid is prevented in low power consumption while water is conserved.
