Description
Technical field
The present invention relates to a kind of refrigeration agent, particularly relate to the mix refrigerant that a kind of energy-conservation refrigerator and refrigerator are used.
Background technology
Refrigerator and the used refrigeration agent of refrigerator are mainly Trimethylmethane (HC)-600a at present.Along with the attention of countries in the world to energy-saving and emission-reduction and environment protection, the research of energy saving refrigerating agent has become focus.But from existing achievement in research, Trimethylmethane-600a environmental protection effect is good, and power consumption is moderate, but safety performance is relatively poor, and potential safety hazard such as set off an explosion easily.Refrigerator and refrigerator are because consumption is very big, and a year electrisity consumption also is extremely huge.If can seek out more energy-conservation refrigeration agent, will bring very big effect to the index of energy-saving and emission-reduction.
Summary of the invention
In order to solve problems of the prior art, the invention provides a kind of refrigerator and refrigerator-freezer energy-saving mixed refrigerant, under the prerequisite that obtains identical refrigerating duty, can obviously reduce refrigerator and refrigerator power consumption.
Energy-saving mixed refrigerant of the present invention, composed of the following components, its quality percentage composition is: Trimethylmethane 1-70%, C2H4F2 C2H4F2 99-30%.
The quality percentage composition of described Trimethylmethane is that 1-50%, C2H4F2 C2H4F2 quality percentage composition are 50-99%.
Adopt refrigeration agent of the present invention to have the following advantages: by pure Trimethylmethane being replaced with the different mass fractional refrigeration agent that Trimethylmethane and C2H4F2 C2H4F2 are formed, can make refrigerator and refrigerator power consumption reduce by 20～50%, to atmospheric ozone layer destroying gesture (ODP) is 0, and the global warming potential that causes (GWP) is between 100～190%.The top pressure operating mode is lower than 0.1Mpa.Compressor oil is ester class refrigeration oil.
Embodiment
Below in conjunction with specific embodiment the present invention is done to describe in detail.
Mix refrigerant of the present invention uses Trimethylmethane (HC) and C2H4F2 C2H4F2 (HFC) double base component, and its quality percentage composition is: the quality percentage composition of Trimethylmethane is that 1-70%, C2H4F2 C2H4F2 quality percentage composition are 30-99%.
In said components, the molecular formula of Trimethylmethane-600a is CH (CH3) 2-CH3, and molecular weight is 58.12, its ozone layer destroying gesture (ODP) 0.0; Its global warming potential (GWP) is 11; The molecular formula of C2H4F2 C2H4F2-152a is CH3CHF2, and molecular weight is 66.05, does not wherein contain the chlorine atom, and its ozone layer destroying gesture (ODP) is 0, and Greenhouse effect (GWP) are 190.
The preparation method of this mix refrigerant is as follows: at normal temperatures Trimethylmethane-600a and C2H4F2 C2H4F2-152a are carried out physical mixed by predetermined mass ratio, form refrigeration agent.Specific practice is, the Trimethylmethane in refrigerator and refrigerator and the refrigerator-600a working medium is all extracted recovery out, and system is vacuumized, and successively Trimethylmethane-600a and C2H4F2 C2H4F2-152a directly poured in refrigerator and the refrigerator system to scale then to get final product.
For the energy-saving effect of more different refrigeration agents with to the influence degree of environment, under envrionment temperature (30 ℃ of room temperatures), compressor, vaporizer and all identical condition of condenser, use pure Trimethylmethane-600a and single and mix refrigerant (as following table 1) to calculate respectively, its energy-conservation data are as shown in table 2 below.
Scale is formed and contained to table 1 mix refrigerant
