Version 3.08 (2013-10-21) - Updated Bock CO2 compressors - Updated Bitzer compressors (hermetic and semihermetic screws are now included) - Added plot of Qe_del_only_MT (i.e. delivered cooling on MT evaporator only - Qe_del_tot_MT included condensing heat from LT system) - Fixed bug related to heat recovery (when ambient temperature was below temperature where heat recovery should be maximum) - Fixed bug related to systems with pumps (control was not implemented correctly) Version 3.07 (2013-07-05) - Translations to the following languages added: - Russian - Romanian - Added several new, and updated several, Bitzer compressors - Added transcritical Copeland Stream compressors - Fixed a number of minor bugs, including: - Proper saving of LCC settings - Correction of calculation of off-design capacity - Added hybrid cooler model (simple efficiency model) - Fixed drawing of two-stage with liquid injection Version 3.06 (2012-09-14) - Changes in installation to better support multi-user PC's and users without administrative privileges - Dutch and French languages added/completed - Published a translation package, which enable users to make their own translations Version 3.05 (2012-08-24) - Fixed bug in "Two one stage, common condenser" systems - PackCalc now comes in the following languages: - Bulgarian (translation not complete) - Czech (translation not complete) - Danish - Dutch (translation not complete) - The translation has been provided by members of the EU-project: "Improving Cold storage Equipment in Europe (ICE-E)" - Added Copeland Stream compressors + added and updated several scroll compressors Version 3.03 (2012-06-11) - Fixed bug in load profile handling. Caused wrong results if: - User created custom load profile - The load profile was not saved to disk - The systems that where compared where not created using the "Copy system" button - If all of the above was true, then all systems where not compared using the custom load profile (the ones created using the "Add System" button, where using a constant load profile) - Added help button to explain all curves on the "Plots" page Version 3.02 (2012-05-28) - Fixed bug when using speed controlled fans and free cooling - Fixed bug when using heat recovery - Fixed minor bugs (text strings, etc.) - Added possibility to change default DT gas cooler out when running transcritical. See "Options|Preferences|Calculation|Condenser control" - Added possibility to have different load profiles for the different systems (currently experimental...). See "Options|Preferences|Calculation|Suction side|Load profile" and "Options|Preferences|Calculation|Heat pump|Load profile". Default is that load profiles are forced to be equal for all systems. - Removed discontinued Copeland compressors Version 3.00 (2012-03-13) - Heat pump model included - One stage system - Air and ground source - Space heating only - Auto-generated compressors. Specify cooling or heating capacity instead of selecting compressors from database - Groundwater cooling can be used as supplement to mechanical cooling (one stage systems only) - Only ATES systems with full thermal balancing included - Instead of specifying the evaporation temperature, it is now possible to specify the evaporator size (for one stage system). I.e. the evaporation temperature is output from calculation. - Updated ZB and ZF compressor models from Copeland - Warnings and errors shown in detail on both monthly energy consumption diagram and summary table - Icon illustrating calculation state next to "Calculate" button (emphasize warnings) - Plots changed so that weather data can be easily displayed - Misc improvements and bug fixes... Version 2.31 (2011-04-01) - Added possibility to include water consumption (and rain water tank) in LCC calculation for cooling tower Version 2.30 - Bug fix so that new Dorin compressors are installed when updating an old version of PackCalc - Changed month and day names so that they are in the same language as the rest of the program (English) Version 2.29 (2011-02-11) - New Dorin range of subcritical compressors (SCC range) added - New Dorin range of transcritical compressors (CD range) added - Improved model of Cooling Tower developed by Danish Technological Institute and Vestas Aircoil - Power consumption when using free cooling included - Possible to specify charge for both high and low side in cascade systems when calculating CO2 emissions - COP calculations for two-stage systems fixed (now condensing heat from low stage is not regarded useful when calculating overall COP) - Several minor fixes and changes... Version 2.28 (2010-09-10) - Load profiles from building simulation program BSim can now be imported. See appendix D in user manual. - 60Hz Dorin CO2 compressors have been included - Minor changes... Version 2.27 (2010-05-03) - Change in calculation of capacity for transcritical compressor in subcritical design condition (change only affects the compressor selection - not the yearly calculation) Version 2.26 - Bock transcritical compressors updated - Dorin SCS compressors added - Changes to userinterface so that users are presented to less options. This can be controlled in Options|Preferences menu Version 2.25 - First proper version
