Title:
FRICTION REDUCING METHOD FOR HEAT TRANSFER SYSTEM FOR REFRIGERATION
Document Type and Number:
Japanese Patent JP2004003808
Kind Code:
A
Abstract:
To provide a friction reducing method selecting friction reducing agent solution and exhibiting the friction reducing effect in the heat transfer method using friction reducing agent and to provide a heat transfer system for refrigeration using the same.
This heat transfer system for cooling and heating comprises a heat supply side system, a heat use side system, and a circulation channel and uses the friction reducing agent solution to be used in the circulation channel whose critical flow speed becomes 3.5m/s or more under the condition of the temperature T of -10°C and the concentration C of 1000-3000ppm.
