Embodiment 1

[0034] The three components of propane (R290), isobutane and trans-1,1,1,4,4,4-hexafluoro-2-butene were subjected to physical analysis in a liquid phase at room temperature in a mass ratio of 40:30:30. Mix uniformly to obtain an environment-friendly mixed working medium.

Embodiment 2

[0036] The three components of propane (R290), isobutane and trans-1,1,1,4,4,4-hexafluoro-2-butene were subjected to physical analysis in a liquid phase at room temperature in a mass ratio of 60:30:10. Mix uniformly to obtain an environment-friendly mixed working medium.

Embodiment 3

[0038] The three components of propane (R290), isobutane and trans-1,1,1,4,4,4-hexafluoro-2-butene were subjected to physical analysis in a liquid phase at room temperature in a mass ratio of 60:15:25. Mix uniformly to obtain an environment-friendly mixed working medium.

Abstract

The present disclosure provides a mixed refrigerant and an air conditioning system, the mixed refrigerant includes a first component, a second component and a third component, wherein: the first component is propane or ammonia, and the second component is isobutane, and the third component is trans-1,1,1,4,4,4-hexafluoro-2-butene. The mixed refrigerant of the present disclosure has low GWP and good thermal performance, and its thermal performance is equivalent to or even better than that of the unit using R134a refrigerant. The refrigerant effectively solves the problem of high GWP of other refrigerants that replace R410A, and also solves the problem of poor thermal performance of other refrigerants.

Description

technical field [0001] The present disclosure belongs to the technical field of refrigeration, and in particular relates to a mixed refrigerant and an air conditioning system. Background technique [0002] With the increasingly serious environmental protection trend, for the "greenhouse effect" of HFCs, the Montreal Protocol Amendment requires a refrigerant that does not damage the ozone layer and has a lower GWP value to replace the current high GWP refrigerant and be effectively used in refrigeration systems. middle. In the existing dehumidification systems, most of the refrigerants used in the system are R134a (GWP=1430), but a more perfect solution to replace R134a has not yet been found. The lower cooling capacity results in a larger compressor volume (larger displacement), which ultimately results in a lower system COP. Since the mixed refrigerant has the characteristics of balanced refrigerant properties, the research on the mixed refrigerant has become a hot spot o...
