Title:
FREEZING CYCLE
Document Type and Number:
Japanese Patent JP3208889
Kind Code:
B2
Abstract:
PURPOSE: To provide a freezing cycle in which, even if a temperature sensing cylinder part is made to have subcooling in a control of the subcooling of a refrigerant condenser in which a heat exchanging part forms a layered structure with respect to a flow of cooling medium, a rising of high temperature and an increase of refrigerant pressure can be minimized, and also cycle performance can stabilized.
CONSTITUTION: In an indoor condenser 14, a heat exchanging part is formed of a first core part 14a, a seond core part 14b and a third core part 14c, and all these core parts 14a to 14c, with the second core part 14b placed between the other two, form a three-layered structure, where the first core part 14a which forms an upstream side of a refrigerant flowing direction is arranged in the air downstream inside a duct 2, while the third core part 14c which forms a downstream side is arranged in the air upstream inside the duct 2. A subcooling control valve 19 is formed of a valve body 19a provided in the downstream of the indoor condenser 14 and a temperature sensing cylinder 19b which is in contact with a bypass pipe 14d interposed in the third core part 14c. It is designed that some amount of subcooling is carried out at a position where the bypass pipe 14d contacts with the temperature sensing cylinder 19b.
