Autocad 2011 Activation Code Generator



Otherwise, visit AVA (Autodesk Virtual Agent) to resolve the issue and automatically receive an activation code or connect with an agent. Provide your serial number, request code, and contact information




Autocad 2011 Activation Code Generator



You can continue to use a previously installed and activated version, even if that version has reached end of support. If you have a perpetual license for a version that has reached end of support, you still have rights to use the license for as long as you want. However, if you are using an unsupported previous version, you will not be able to receive a new activation code to reactivate it on any device, for instance in case of a hardware failure. In addition to the potential downtime this might cause, security issues may arise because you will not be receiving software updates or hotfixes.


Absorption heat pumps have received renewed and increasing attention in the past two decades. The rising cost of electricity has made the particular features of this heat-powered cycle attractive for both residential and industrial applications. Solar-powered absorption chillers, gas-fired domestic heat pumps, and waste-heat-powered industrial temperature boosters are a few of the applications recently subjected to intensive research and development. The absorption heat pump research community has begun to search for both advanced cycles in various multistage configurations and new working fluid combinations with potential for enhanced performance and reliability. The development of working absorption systems has created a need for reliable and effective system simulations. A computer code has been developed for simulation of absorption systems at steady state in a flexible and modular form, making it possible to investigate various cycle configurations with different working fluids. The code is based on unit subroutines containing the governing equations for the system's components and property subroutines containing thermodynamic properties of the working fluids. The user conveys to the computer an image of his cycle by specifying the different subunits and their interconnections. Based on this information, the program calculates the temperature, flow rate, concentration, pressure, and vapor fraction at each state point in the system, and the heat duty at each unit, from which the coefficient of performance (COP) may be determined. This report describes the code and its operation, including improvements introduced into the present version. Simulation results are described for LiBr-H2O triple-effect cycles, LiCl-H2O solar-powered open absorption cycles, and NH3-H2O single-effect and generator-absorber heat exchange cycles. An appendix contains the user's manual.
