Air Conditioning

Proper System Integration of Air Conditioning systems by Tier’d suppliers and OEM’s is vital in maintaining acceptable performance characteristics as cost and packaging constraints are imposed. Physical testing of design changes is expensive and time consuming.

The Air Conditioning (AC) System Modelling packages from Flowmaster allow you to design and optimise your AC system during the early stages of design to optimise component selection and overall system design. For example Flowmaster Automotive AC allows you to understand;

  • the AC system power requirement on the engine
  • how the AC system affects other circuits in the vehicle, such as the coolant loop
  • the Temperature and humidity of the air entering the cabin

To help you build your AC models, Flowmaster V7 Automotive AC Systems packages come complete with a wide range of standard and AC specific components, including;

  • Heat Exchangers (condenser’s, evaporator’s etc)
  • Expansion Valves
  • Capillary Tubes
  • Controllers and Gauges
  • Pumps and Valves
  • Comprehensive Fluids & Refrigerant Database

Modelling Cabin Environment

By simulating cabin entry temperatures, pressures and flow rates you can predict and verify air humidity and air re-circulation factors, making it easier to optimise your cabin environment for:

• Occupant comfort
• Driver alertness
• Warm-up & pull-down

The Flowmaster V7 Cabin Component, available with V7
Automotive Vehicle Thermal Management licenses, enables users to model the vehicle cabin in conjunction with the HVAC system to provide a total vehicle thermal management solution.

By taking into account different thermal loads, air flows, cabin sub-components and environmental factors the cabin component is able to predict the mean temperature of the
cabin air space and predict the temperatures of the roof, instrument panel, floor, windscreen and rear window during and following a transient simulation.

Features:

  • Model heat transfer effects for both steady state and transient flow conditions using a wide range of heat transfer options
  • Model all common types of AC system; TXV, FOT, VOT with a wide range of standard and AC specific components
  • Configure evaporator’s and condenser’s with performance data
  • Co-Simulate with other industry tools such as ANSYS FLUENT, Star CD and MATLAB®/Simulink®

Benefits:

  • Determine the power requirement of the compressor and the temperature and humidity of the air entering the cabin
  • Determine the effect of AC system performance on adjacent thermal systems, fuel economy and passenger comfort
  • Use System Simulation to accurately predict AC system behaviour with minimal data requirements
