PURPOSE:To provide a mixed hydraulic fluid contg. specified two Flons as essential components, which has low toxicity, is incombustible and chemically stable, has a high efficiency of heat recovery and is useful for heat pumps, etc. CONSTITUTION:The mixed hydraulic fluid contains (A) monochlorodifluoromethane and (B) monochlorotrifluoroethane as essential components in an A/B blend ratio of 1/1-1/100. The mixt. has a high efficiency of heat recovery, low toxicity and incombustibility, is chemically stable and is esp. effective for application in heat pumps which utilize a medium or low temp. heat source. It has excellent heat stability and usually requires no addition of stabilizer, but under severe conditions of use, it is preferable that a stabilizer such as dimethyl phosphite be added in a small amount to improve heat stability. |
