Refrigerant Slider

By Danfoss A/S

Open iTunes to buy and download apps.


Danfoss proudly presents Refrigerant Slider, the essential tool for all HVAC-R professionals.
Based on the well-known Danfoss Refrigerant Slider, KoolApp™ turns your iPhone or iPod Touch into a user-friendly, quick pressure-to-temperature refrigerant converter. It is designed for installers, distributors and producers of air conditioning and refrigeration equipment, and will also be useful for other industry professionals and students.
In the current version there are 48 different refrigerants including both “natural” and “traditional” refrigerants, covering almost all media normally used in air conditioning and refrigeration systems. More will be added via updates pending user requests.

KoolApp is based on the NIST Refrigerant Properties and is using the Antoine equations for the conversion and you will be able to see both dew- and bubble- points for refrigerants with glide.
Included are also a few additional informations regarding the respective refrigerants.
On the respective refrigerants, you can see additional information like Global Warming Potential (GWP) and Ozone Depleting Potential (ODP).

KoolApp™ gives you the freedom of calculating in either °C and bar, or °F and psi.

In the left side of the screen, an intuitive slider helps you to quickly find the pressure or temperature reference, while the precise pressure and temperature reads on the right side fields.
By simply tapping these fields, you can also type in your actual pressure or temperature reading, and KoolApp™ will instantly give you the corresponding figure – and move the slider for visual indication.
Changing from SI units to US Customary units is a one-button operation, and you can do this directly within the conversion tool.
KoolApp™ gives you more than 48 refrigerants, but also allows you to select your favourites among them, making them easily accessible on the top of the selection list.

What's New in Version 2.0.5

Danfoss has upgraded the Refrigerant Slider with more information per refrigerant like recommended lubricant, safety group, chemical name, composition, colour code of containers etc.
To access the additional information, please tab the arrow right of the refrigerant name in the lower right pane.
There are a few functional changes like being able to switch between “dew-” and bubble-” point data for refrigerants with glide without having to change refrigerant, which makes the Refrigerant Slider more convenient to work with. Also other minor inconveniences have been corrected, such as limits to CO2 and relative/absolute measuring’s per unit.
We have also added a few more refrigerants and added missing translations.
Please keep sending us feedback and suggestions to improvements and ideas for extensions either via the Koolapp e-mail or post it in the store reviews.

Customer Reviews

Good app.

It's quick to use and easy to read.
*current update deleted all favorites: delete app from phone and re-download(or get off of cloud). This fixes it.

Critical power and cooling

Last update removed r22, 410a, and 407c. Is it hiding somewhere? It was a 5 star app until that.

Last update removed slider for ammonia

I used your app a lot for the ammonia R-717 slider, but now I can not find it anymore. Did you remove it?
