Technical field
The present invention relates to refrigeration technology field, and in particular to a kind of highly effective refrigeration agent and preparation method.
Background technology
Refrigerant, also known as refrigeration working medium, are the working medias of kind of refrigeration cycle, are to transmit heat using the phase transformation of itself,
Absorbed heat when i.e. refrigerant is vaporized in evaporator, heat release when liquefying within the condenser.
Up to the present, family expenses, the commercial refrigerant occurred mainly includes freon class refrigerant and hydrocarbon refrigeration
Agent.
Freon refrigerant refers to chloro-fluoro-carbon kind compound, including dichlorodifluoromethane, Freon 13, the chlorine of difluoro one
Methane etc., freon is the arch-criminal of depletion of the ozone layer, because their average life spans in an atmosphere reach centuries, so discharge
Major part is remained in atmosphere, and wherein most remains in troposphere, and sub-fraction rises up into stratosphere.Freon is upper
Rise and enter after stratosphere, under certain meteorological condition, can be decomposed in the presence of intense UV rays, decompose the chlorine discharged
With ozone chain reaction can occur for atom, constantly destroy ozone molecule, and scientist estimates that a chlorine atom can destroy tens thousand of
Ozone molecule.Wherein monochlorodifluoromethane is due to refrigeration performance, thus in the development later stage of freon, most widely used,
Application time is longer, but due to its heavy damage to ozone layer,《Montreal Protocol》Clear stipulaties, developed country from
Stop the production and consumption of monochlorodifluoromethane from 1 day January in 1996 completely, the last deactivation date of developing country is
On January 1st, 2010.Under these circumstances, each state has all carried out the research work of the alternative refrigerant of freon.
Therefore, research and develop it is a kind of both there is preferable refrigeration, can avoid again freon use have compared with
The refrigerant of good environmentally friendly feature is significant, also complies with the demand of existing market.
The content of the invention
It is described it is an object of the invention to provide a kind of highly effective refrigeration agent and preparation method for defect of the prior art
Highly effective refrigeration agent not only have preferable refrigeration, can avoid again freon use have preferable environmental-protecting performance,
With preferable application value.
