Abstract
Process cooling and air conditioning are becoming increasingly important in the industry. Refrigeration is still mostly accomplished with compression chillers, although alternative technologies are available on the market that can be more efficient for specific applications. Within the scope of the project “EffiCool” a technology toolbox is currently being developed, which is intended to assist industrials users in selecting energy efficient and eco-friendly cooling solutions. In order to assess different refrigeration options a consistent methodology was developed. The refrigeration technologies are assessed regarding their efficiency, CO2-emissions and primary energy consumption. For CCHP systems an exergetic allocation method was implemented. Two scenarios with A) a compression chiller and B) an absorption chiller coupled to a natural gas CHP system were calculated exemplarily, showing a greater overall efficiency for the CCHP system, although the individual COP of the chiller is considerably lower.

Summary
The provision of process cooling and air conditioning for industrial needs is becoming increasingly important. In practice conventional compression chillers are still used as standard solution for cooling in most cases, due to low investment costs and ease of implementation. These systems are not necessarily optimized in terms of energy efficiency, eco friendliness, and total lifetime costs. There is a wide range of alternative refrigeration technologies already available today which can present a better, more efficient option for the given application than the standard solution. One of the major goals of the project is to develop a technology toolbox, which is intended to assist industrials users in selecting energy efficient and eco-friendly cooling solutions.
