Benefits of Ammonia Absorption Machines
Compared to other technologies, there are various benefits of ammonia absorption machines. Find below a list with a brief description of these.
Zero GWP and ODP
With its zero Ozone Depletion Potential (ODP) and zero Global Warming Potential (GWP) the use of ammonia has no negative impact on the environment.
Natural Refrigerant
Ammonia as a natural refrigerant with good cycle efficiency and low costs is well positioned for future legislations with regard to protection of the environment.
Low Maintenance Costs
Pumps and valves are the only moving components in an ARP. They don’t require much maintenance. The plant itself is a closed circuit and not susceptible for repair or maintenance works.
Low Power requirements
In comparison to compression machines an ARP requires much lower power consumption. Cooling towers and/or evaporative coolers or dry coolers are the main power consumers. Inside the ARP there are only small consumers like pumps.
Automatic Operation
An ARP can be equipped with a fully automatically control system so that no manpower is needed for daily operation.
Robust Technology
An ARP consists mainly of heat-exchangers and piping. These components are not susceptible for downtime or disturbances.
Waste Heat as Driving Energy
The main energy input for an ARP is heat (look at page: Working Principle). This heat can be residual heat from any chemical or power plant process.
Excellent Partial Load Behavior
The standard version allows partial load down to 30% capacity with nearly constant COP. Further load decrease to 0% is also possible.
Long Lifetime
A closed circuit, heat-exchangers and piping as main components ensure a long lifetime. More than 30 years for such plants are not unusual.
No Special Spare Parts or Specialists Required
All components used are standard industrial products which are easily available all over the world. Anyone who is allowed to work with ammonia can do maintenance or repair works. No specialists are required.
