Typical automotive air conditioning refrigeration systems employ thermostatic expansion valve or orifice tube controls in a single stage refrigerant circuit. A new automotive air conditioning compressor has been developed that has a two stage compression process, which makes designing and producing a two stage refrigerant circuit more practical. Since this compressor can function in a single st...

A new methodology is proposed to use comprehensive up-to-date commercial software tools for Heat Exchanger Network (HEN) reliability modelling and optimisation. The idea behind this proposal that apply the combination of specific HEN optimisation packages has several advantages over commonly used approach. There a variety features need be taken into account choose right tool. design significant...

Dynamic models of vapor compression systems are important tools for HVAC engineers in the development and evaluation feedback control and fault detection and diagnostic (FDD) algorithms. Significant literature exists on dynamic models of vapor compression systems. Much of it is restricted to air-to-air systems and few papers deal with liquid chillers. Most of existing liquid chiller models revi...
