Vapour Cycle Air-Conditioning

Vapour cycle refrigeration is the predominant means of air-conditioning in small- and medium-size business aircraft and helicopters. These systems use a refrigerant-based air-conditioning process for cooling the passenger cabin and equipment.

As a supplier, you are under pressure to design the smallest, lightest and most efficient air-conditioning equipment for OEM or after-market fitment. Your customers increasingly demand this because:

  • Reduced size leads to easier packaging in the limited space available, giving greater opportunities
  • Reduced weight leads to lower payload penalty, giving better operating margins
  • Increased efficiency leads to lower power input consumption, reduced ram-air requirement and hence lower airframe drag, giving large fuel and cost savings.

The challenge is to get your product to market before your competitors. The sooner you do this with a superior product the faster you build your market share.

You can achieve this with Flowmaster® air-conditioning simulation software. With this market-leading product you can:

  • Determine power input requirements
  • Size the system components to get exactly the performance you want
  • Evaluate variables such as the coefficient of performance (COP = - evaporator duty / compressor power)

Flowmaster, a Windows® based software package, gives you a drag-and-drop modelling environment that is quick to learn and easy to use. The software is highly productive - you quickly become familiar with the analysis environment and become able to build models, run simulations and get useful results in very short timescales. With the software you get a comprehensive range of air-conditioning components and refrigerant properties. Optionally, you can input fluid property curves and surfaces to define your own refrigerants or refrigerant/oil mixtures.

Flowmaster air-conditioning capability has been developed as a system design tool - modifying a few parameters and shape factors will allow you to achieve the desired performance. This allows you to specify the individual component characteristics to your manufacturing team or suppliers.
