Description
Technical field
The invention belongs to refrigerant art, relate to a kind of refrigerant composition, relate in particular to a kind of refrigerant composition that is applied in the refrigerated air-conditioning systems such as domestic air conditioning/heat pump.
Background technology
According to the script regulation of Montreal protocol, developed country will stop the R22 production and consumption of non-feedstock property fully in the year two thousand thirty, and developing country's (comprising China) will stop the R22 production and consumption of non-feedstock property in the year two thousand forty.But in the up-to-date resolution that the Montreal protocol conference of contracting party that Montreal, CAN is held in September, 2007 is reached, developed country will stop the R22 production and consumption of non-feedstock property fully in the year two thousand twenty, the developing country that comprises China, be frozen on the mean level (ML) of 2009 and 2010 the production and consumption amounts with non-feedstock property HCFCs (wherein about 70% is R22) in 2013, the year two thousand thirty finishes comprehensively and eliminates.Compare original timetable, whole superseded process shifts to an earlier date greatly, and systems such as present domestic domestic air conditioning/heat pump about 80% adopt R22 to make refrigeration agent, and the research and development of its alternative situation and substitute are extremely urgent.
Current, the main substitute of R22 comprises R407C (R32/125/134a) and R410A (R32/125) etc. on the domestic and international market, but these substitutes are still undesirable, for example, the efficiency of R407C is lower, and its slip temperature is bigger, and these problems have restricted its market and used, and take as the leading factor with R410A gradually in market; But the mineral oil (MO oil) that R410A and R22 system use is incompatible, need be replaced by bibulous ester class oil (POE oil), and POE oil price position is higher and water-absorbent causes refrigerated air-conditioning system to take place to ice stifled by force easily, in addition, how to reduce the influence of its GWP value and can further improve problems such as system energy efficiency again and still need further to probe into again.On the substitution problem of R22, researcher is constantly being done effort, but passes through the exploration of more than ten years, still can not find the pure working medium of a kind of ideal and substitutes R22, and replacement scheme still is to adopt mixture.
