Title:
COMPRESSION TYPE REFRIGERATION MACHINE
Document Type and Number:
Japanese Patent JP2015161421
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a compression type refrigeration machine capable of discharging noncondensing gas in an extraction tank without using a vacuum pump, and capable of discharging noncondensing gas in the extraction tank without hindrance even in a case of providing an adsorber.SOLUTION: A compression type refrigeration machine includes an evaporator 3, a condenser 2 and a compressor 1, and uses refrigerant having a possibility that pressure is equal to or less than atmospheric pressure in the evaporator 3. The compression type refrigeration machine also includes: an extraction tank 6 that is connected to the condenser 2, and extracts refrigerant gas containing noncondensing gas from the condenser 2; a cooler 7 that is provided inside the extraction tank 6, and vaporizes refrigerant liquid supplied from the condenser 2 to cool the inside of the extraction tank 6; and heating means that heats the inside of the extraction tank 6 to increase inner pressure of the extraction tank 6.
