R134a convert to R507
Hi onboard my ship we are going to convert our provision cooling plant from R134a to R507.
We are told this will give us more cooling power.
Does anyone know how many % more we get from this convertion ?

Re: R134a convert to R507
If you have 100 kW you can count about 150 kW, depending on the regime the compressors are working on.
Pay attention to the compressor motors and the condenser (with R507 there will be more needs of that elements).To make progress is never good enough, I want to do better and better and better

Re: R134a convert to R507
We are going to mount a cooling pump with larger flow.
Is the motor going to use more amps ?
(is this due to higher pressure or what)

What motor you are talking about? Compressor motor?

Re: R134a convert to R507
The motor if sized corectly for R134a will be too small for R507 due to the increased mass flow. If you are using a shell and tube condenser it may still not be suitable even with increased pump flow and may also need changing. If you are using medium temperature you are better to stick with R134a and upgrade the plant. You may also find R507 hard to obtain in some ports.
