R507 Pressure-Temperature Chart

Hello readers welcome to the new post. Here we will learn the R507 Pressure-Temperature Chart. R507 is an azeotropic mixture of R125 and R143a having zero ozone depletion potential. It is the safe and best alternative for CFC and HCFC refrigerants like R502. The HFC comes with the same featues as R502 and operates well in commercial refrigeration systems employed in transport refrigeration. Let’s get started with R507 Pressure-Temperature Chart

Features of R507

It is replaced tof R502 so it can work for the complete R50e operating range
It has efficiency and capacity close to R502.
it working operation that is consistent with the leakage cycle no separation if leakage exists.
The compressor discharge temperatue is 7.4 °C (13.3 °F) lower than R502 which can causes longer compressor life.
it is no flammable material.

What is R507 refrigerant?

R507 is an HFC blend used to work as an alternative to R22 and R502 in low to medium temperatue refrigeration

Where is R507 used?

R507 is a non-flammable refrigerant used in applications for the operation of cold storage rooms, Refrigerated display cases, ice cream flooded systems.

Is R404A the same as R507?

R404 is a non-azeotropic mixture and is filled in a liquid state while R507 zerotropic mixture. The existence of R134a in R404a enhances mass transfer resistance and minimizes the heat coefficient of the transfer chamber, while the heat transfer coefficient of R507 is higher than R404a.

Can R507 replace R22?

Normally it is suggested that R507 can be used as retrofitting refrigerant in window air conditioners and made to use R22 in place of HCFC phased out.

Is R507 flammable?

It is non-flammable at ambient temperature and atmospheric pressure. But this material is combustible if mixed with air under pressure and exposed to strong ignition sources.

What oil does R507 use?

polyol ester refrigerant oil

Is R507 heavier than air?

The R507 is asphyxiant and avoids areas where spillage takes place. Only enter when proved atmosphere to safe and gas is heavier than air.

What is the running pressure for R507 refrigerant?

The average running pressure value is 280 to 310 #.

What is the boiling point of R507 refrigerant?

Boiling point(101.3kPa，℃)

-46.7

How do I charge my r507a?

The R507A must be charged in the liquid phase to make sure accurate composition used in the refrigeration system. For conditions where vapor is charged in the system valve must be connected in the charging line to flash liquid to vapor during charging.
