Title:
REFRIGERATING SYSTEM
Document Type and Number:
Japanese Patent JP09170827
Kind Code:
A
Abstract:
To reduce the range of the operating condition for reducing the operation coefficient.
A closed refrigerating system comprises a compressor 12, an oil separator 14, a normally closed valve 16, a condenser 18, economizer means 20, an evaporator 24, and a valve control means with an operating envelope line. The valve 16 is connected (28) to the means 20 in a fluid manner so that the economizer pressure urges the valve so as to close the valve 16. On the other hand, the discharge pressure of the compressor 12 urges the valve 16 so as to open the valve 16. The throttling operation of the flow is conducted only in the local area of the envelop line, and the valve 16 is fully opened in the other area.
