Problems solved by technology

The above-mentioned mixed refrigerants are only suitable for a certain range of applications and have relatively large limitations, because the above-mentioned refrigerants have their own fixed characteristics and scope of application, and none of the mixed refrigerants can be applicable to different evaporation temperature regions and condensation temperature regions at the same time, and The refrigerants introduced in these prior patents have limited energy saving effects in refrigeration, heat pump and air conditioning equipment, generally 5-10%
In addition, the use of prior refrigerants often requires more modifications to the original refrigerants, heat pumps and air-conditioning equipment before they can be applied, which will bring many difficulties to practical application and promotion

Abstract

The invention relates to an energy-saving environment-friendly non-azeotropic mixed refrigerant, comprising 3-40% of R1270(C3H6), 20-85% of R152a(CH3CHF2), and 3-40% of R600(C4H10) and/or R600a(C4H10), wherein the R600(C4H10) and R600a(C4H10) can be used separately or mixed in any ratio for use. The energy-saving environment-friendly non-azeotropic mixed refrigerant is nondestructive to atmospheric ozonosphere, causes no greenhouse effect, and can be used in air conditioners and heat pump devices to save energy by 30-45%; when applied to refrigerating equipment, the energy-saving environment-friendly non-azeotropic mixed refrigerant can save energy by 25-45%, and is an environment-friendly mixed refrigerant widely applicable to refrigerating, heat pump and air conditioning devices and having significant energy-saving effect.

Description

technical field [0001] The invention relates to the technical field of refrigeration engineering, in particular to an energy-saving and environment-friendly non-azeotropic mixed refrigerant suitable for air conditioners, heat pumps and refrigeration systems. Background technique [0002] As we all know, Freon R12 has been used as a refrigerant for refrigeration, heat pumps and air-conditioning devices for a long time, and has made some contributions to the development of refrigeration engineering technology. The environmental crisis in the world poses a great threat to human existence, because Freon R12 seriously damages the atmospheric ozone layer on which human beings depend for survival. The Montreal Protocol clearly stipulates that Freon R12 is an absolutely controlled and prohibited refrigerant substance. Therefore, the vast number of scientific and technological workers in the world, especially those engaged in the development and research of refrigeration engineering ...
