Title:
冷凍機
Document Type and Number:
Japanese Patent JP6398621
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve heat exchange efficiency by reducing occurrence of leakage and outgas that deteriorate a degree of vacuum in a refrigerator with an evaporator to boil and evaporate a refrigerant.SOLUTION: A gas phase refrigerant in a condenser 30 is introduced into a liquid phase refrigerant in an evaporator 40 through a refrigerant return pipe 52. This causes air bubbles to blow into the liquid phase refrigerant in the evaporator 40, and then causes disorder in the liquid phase refrigerant in the evaporator 40, thereby facilitating boiling nucleation to improve heat exchange efficiency.SELECTED DRAWING: Figure 1
