Special description: freon is transparent, tasteless, low toxic, medium constant low, critical temperature high, liquid. Freon and water are almost insoluble with each other and the resolution of moisture is minimal. It is generally soluble in refrigerated oil, but at high temperatures freon is deciphered from the refrigerated oil. Freon r22 is non-fired, non-explosive and safe from ammonia in use. R22 has a volume of about 60 per cent higher than r12 and a volume of cooling and saturation pressure at low temperatures is higher than r12 and ammonia. For safety reasons, the following is provided to define whether there is a leak: 1. Up to 10 per cent of freon is replenished annually, which is normal natural wear (e. G., replacement of valves, oil, filter cores, etc.). 2. More than 10 per cent of freon replenishment per year is due to leakage caused, for example, by loose piping or other valve valves; if maintenance costs arise during the warranty period, they are handled by b, with the exception of human and irresistible factors; if leakage is detected after the warranty period, it is determined, on the basis of actual circumstances, that leakage occurred in the pipe interface and is handled by b. 9.
