Embodiment Construction

[0015] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below in conjunction with examples.

[0016] As described in the background art, the existing refrigerating compositions cannot guarantee low GWP, low ODP and good thermodynamic performance, but also have low flammability. In order to solve the above technical problems, the application provides a ternary refrigeration composition, which is composed of a first component and a second component, wherein the first component is fluoroethane, and the second component Any two selected from 1,1-difluoroethane, difluoromethane and 2,3,3,3-tetrafluoropropene.

[0017] The environmental characteristics and thermodynamic properties of fluoroethane (R161) are similar to those of R290, but the flammability is lower than that of R290. By using fluoroethane together with th...

Abstract

The invention provides a ternary refrigeration composition and a refrigeration device comprising the same. The ternary refrigeration composition is composed of a first component and a second component, the first component is fluoroethane, and the second component is selected from any two of 1, 1-difluoroethane, difluoromethane and 2, 3, 3, 3-tetrafluoropropene. According to the present invention,the environmental protection property and the thermodynamic property of fluoroethane are similar to those of R290 while the combustibility of fluoroethane is lower than R290, and fluoroethane and thesecond component with the combustibility of class 2 or 2L are used together, so that the refrigeration composition can have characteristics of low GWP, good thermodynamic property and low combustibility grade, and the use safety is improved; the ternary refrigeration composition has an ODP value of zero, and does not cause damage to the ozone layer even after long-term use. Therefore, the ternaryrefrigeration composition has lower GWP, ODP is 0, the combustibility is 2 types, and the capacity and the energy efficiency of a unit are equivalent to those of a unit using an R290 refrigerant whenthe ternary refrigeration composition is applied.

Description

technical field [0001] The invention relates to the technical field of refrigeration materials, in particular to a ternary refrigeration composition and a refrigeration device containing it. Background technique [0002] In the context of global warming, refrigeration technology is facing two major pressures of "environmental protection" and "energy saving". Finding environmentally friendly and efficient alternative working fluids is a key issue that the refrigeration industry needs to solve urgently. Natural working fluid propane (R290) is considered as one of the future alternative refrigerants due to its zero ozone depletion potential (ODP), extremely low global warming potential (GWP) and good thermodynamic properties. R290 has been used in air conditioning systems, refrigerators and small refrigerators in Germany, Sweden and other EU countries. India has also realized the marketization of R290 air conditioners. Domestic companies such as Gree, Midea, and Haier took the...
