Extreme low charge refrigeration systems with R-717
R-717 is one of the most efficient natural refrigerants available with wide usage possibilities. Its downside is that it is toxic.
That is why all R-717 refrigeration systems must be designed with safety in mind. We will describe various solution to achieve this by reducing the charge.

Session description
HFC refrigerants are common refrigerants, but also strong global warming gases which will be phased out going forward. The more recent developed HFOs, although not being strong greenhouse gases, are often questioned due to other environmental and safety concerns. As a result, users are turning more to systems using natural refrigerants. R-717 is for example one of the most efficient natural refrigerants available, with wide usage possibilities from high to low temperatures and up to very large capacities. Apart being a natural substance, the use of ammonia opens for possibilities to reduce energy consumption, and secure for long term cost efficiency and sustainability.
One important and growing type of installation is low-charge ammonia refrigeration systems. These systems ...
