Description
Technical field
The present invention relates to the technical fields of mix refrigerant, more particularly to a kind of New-type environment-protecting mixed refrigerating agent.
Technical background
Refrigerant, also known as refrigerant, refrigerant, snow kind are the media materials converted in various heat engines so as to completing energy, this
A little substances are usually with reversible phase transformation (such as solution-air phase transformation) Lai Zeng great power, such as the steam in Steam engine, the snow in refrigeration machine
Kind etc., at work, the thermal energy of steam is released for general steam engine, is converted into mechanical energy to generate motive power；And
The snow kind of refrigeration machine is then used to for the heat at low temperature being transferred at high temperature.
With the continuous enhancing of people's environmental protection concept, the mankind start constantly to research and develop and select more environmentally-friendly refrigerant,
R404A belongs to HFC type non-azeotropic environmental protection refrigerant (not destroying CFC, HCFC of ozone layer completely), and it is most absolutely to obtain the current world
