==REFRIGERANT COMPOSITIONS AND USE THEREOF IN SYSTEMS USING FLOODED EVAPORATORS - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18382235 titled 'REFRIGERANT COMPOSITIONS AND USE THEREOF IN SYSTEMS USING FLOODED EVAPORATORS

The patent application describes a method for retrofitting an existing heat transfer system by adding a specific refrigerant mixture.

* The refrigerant mixture consists of 1,1,1,2-tetrafluoroethane (HFC-134a), trans-1,3,3,3-tetrafluoropropene (HFO-1234ze(E)) and/or 2,3,3,3-tetrafluoropropene (HFO-1234yf), difluoromethane (HFC-32), and pentafluoroethane (HFC-125) in specific weight ratios.
* The refrigerant is non-flammable and has a Global Warming Potential (GWP) of 1350 or less.

Potential Applications:
* Retrofitting existing heat transfer systems in various industries such as HVAC, refrigeration, and automotive.
* Enhancing energy efficiency and reducing environmental impact in cooling systems.

Problems Solved:
* Addressing the need for more environmentally friendly refrigerants with lower GWPs.
* Improving the performance and efficiency of existing heat transfer systems.

Benefits:
* Reduced environmental impact due to lower GWP refrigerant.
* Enhanced energy efficiency and cost savings in cooling systems.

Commercial Applications:
* HVAC systems in commercial buildings.
* Refrigeration units in supermarkets and food storage facilities.
* Automotive air conditioning systems.

Questions about the technology:
1. How does this refrigerant mixture compare to traditional refrigerants in terms of performance and efficiency?
2. What are the potential challenges in retrofitting existing heat transfer systems with this specific refrigerant mixture?


==Original Abstract Submitted==

Method for retrofitting an existing heat transfer system comprising adding to said existing system a refrigerant consisting essentially of: (i) from about 25% to about 45% by weight of 1,1,1,2-tetrafluoroethane (HFC-134a); (ii) from 25% to about 35% by weight of trans-1,3,3,3-tetrafluoropropene (HFO-1234ze(E)) and/or 2,3,3,3-tetrafluoropropene (HFO-1234yf); and (iii) from about 37% to about 46% by weight of a combination of difluoromethane (HFC-32) and pentafluoroethane (HFC-125), provided that the weight ratio of HFO-32:HFC-125 is from about 1.21:1 to about 0.8:1, wherein the refrigerant preferably is a non-flammable refrigerant having a GWP of 1350 or less.
