A new Chiller Performance Analysis coming!

     In order to find the balance point of a air conditioning (AC) system, you need to find a simultaneous solution between the compressor, the evaporator and the condenser.  This can be done numerically by calculating the system performance at specific definite time.  The problem with this approach is that it does not cater for component design changes.  Clearly, a computer model offers much advantage in the speed of solution but also in avoiding errors. We often have discussed a theoretical and a practical approach.  Our preference was to adopt a pseudo-practical method where the AC system performance are calculated in detail but the data is based on a offline data.  The practical model is easy to apply numerically and can be extended to include all types of AC types. In heat pump applications, it is essential that the balance point be determined under peak heating and cooling conditions.  To find a suitable design, the designer would need to perform a number of system balances.  The benefit of a numerical AC simulation to test these design changes is obvious. Now, we propose CHieVA 2.0 as one of Chiller Performance analysis tool. CHieVA 2.0 is developed in the light of simplicity of thermal performance analysis but yet it capable to obtain detail thermal performance analysis as configuration of the system was changed.  Please feel free to contact me if you need more information on CHieVA 2.0. The  CHieVA 2.0 will be released on the mid of October 2010. You can donwnload it for free and use it as limited version. Here, we show you view screen shoot of CHieVA 2.0.
