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

An energy-saving environment protection type composite non-azeotropic refrigerant contains (R1270 (C3H6) (3-40 wt.%), R152a (CH3CHF2) (20-85), R600 (C4H10) and R600a (C4-H10). Its advantages are no damage to ozonosphere and saving energy by 25-45%.

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. technical background [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 ...
