Product Development
Abstract
Problem statement:
Consumption of bottled water has increased considerably the last decade. Transportation of bottles and exploration of natural wells, effect the environment negatively. By developing a product that produces pure and safe drinking water right on the spot, would both save money for the customer and spare the environment.

Purpose:
The primary target goal has been to come up with a new concept solution that can harvest water out of thin air. The aim with the new technology is to beat other air to water
products on the market today by making the water production reliable even in arid zones.

Method:
The project has been executed by using a model set up at Stanford University. The selection of generated... (More)
Problem statement:
Consumption of bottled water has increased considerably the last decade. Transportation of bottles and exploration of natural wells, effect the environment negatively.

Purpose:
The primary target goal has been to come up with a new concept solution that can harvest water out of thin air. The aim with the new technology is to beat other air to water
products on the market today by making the water production reliable even in arid zones.

Method:
The project has been executed by using a model set up at Stanford University. The selection of generated concepts has been executed by using a method developed by Ulrich and Eppinger.

Results:
Choosing the right method to extract water out of air is highly dependent on the prevailing relative humidity as well as the temperature of the air. In humid climate conditions, direct refrigeration in order to condense water has shown to be the most effective method. In drier environments below an RH level of 30-45% this process becomes highly energy consuming and the production capacity decreases considerably. In these conditions implementation of hygroscopic substances has shown to be a promising substitute solution. By first absorbing moist from air using desiccants, major energy losses are avoided, which direct refrigeration entails in order to enable the condensation process. The absorbing substances can thereafter be regenerated by heat and condensate is extracted in an effective way. (Less)
