do the same job. My calculations suggest that you could save as much as 3kg of refrigerant product which is again good news for the bottom line.


A ll these elements make R1234ze a viable alternative to R134a on chiller applications where these kind of savings really can make a difference. R1234ze is a single element product – not a blend – and that means there is no glide to worry about. These calculations can be a tricky area for some engineers, so to my m ind if you can take them out of the equation altogether, why not?


R1234ze also has a higher Co-effi r Co-effi fficient o f


Performance (CoP) than R134a so in this respect too you are also getting more for your money. R 1234ze is a good fi t for large chiller a pplications and manufacturers have been putting this gas to practical use with equipment designed specifically for this refrigerant – and reports suggest it is working well.


Because it is a single component – and not a retrofi t alternative – in many instances you w ill need a larger swept volume compressor for the system but this should not be a barrier to make the switch. In the context of the F-Gas Regulations, it’s never been more important


c hoice now is only going to save the end user money in the long run.


R1234ze is a sound alternative to R134a a nd, especially in the case of large chiller applications, is very much the compressor’s


mate and the power supplies’ best friend too. The GWP fi gures also stack up and in respect of global warming and the green agenda it’s a gas you’ll want to be aware of. It could make a big d ifference to the way you work.

Solstice ze (HFO R1234ze) Solstice ze (HFO R1234ze) H


oneywell’s new Solstice ze refrigerant (HFO-1234ze) is the best medium pressure, low GWP refrigerant on the market when considering the balance of all properties.


It is an energ rgy-efficient alternative to traditional refrigerants


in different medium temperature uses and has been selected by a number of equipment manufacturers or for applications with a capacity range from several kW to 20MW and charges varying from 300g to 13mT.


Solstice ze meets the criteria most important to refrigerants users: performance, cost effectiveness, environmental impact and safet y. It has a GWP of <1 which exceeds existing climate protection goals . The refrigerant:


■ helps with eco-design directives ■ reduces direct CO2 emissions by 99.6 percent


■ reduces indirect CO2 emissions due to the lower energy consumption


■ has an atmospheric life of only 18 days – much lower than the 13 years of R134a.
