Since DSIMAC is designed as component-based tool with friendly user interface, one can easily develop vapor compression system to perform static simulation & analysis.
Traditional static simulation is focused on modeling of equipment itself. However, actual system involves a lot of controls of actuators. A good simulation should behave as real system with real controls.
DSIMAC simulation platform is an excellent tool to help engineer to achieve the true needs with real controls. Below is the static simulation with outdoor fan targeting on SDT (discharge saturation temperature) which is equal to a+b*OAT and compressor speed targets house temperature with set point as a+b*OAT.
Extensive research and development have been performed on the air conditioning and refrigeration system with carbon dioxide (CO2) as the refrigerant due to its zero ozone depletion potential (ODP) and negligible global warming potential (GWP). . However, due to its high pressure level, high power consumption, etc., the design and analysis of the system with CO2 becomes a challenging to engineers, compared to a traditional refrigeration cycle.
DSIMAC simulation platform is an excellent tool to help engineer to achieve their design targets such IEER points, etc.
Ranging from the refrigerated food chain to air-conditioning of residences and commercial buildings, vapor compression systems are widely used for cooling or heating.
However, according to the Energy Information Administration, approximately one third of the electricity consumed in a building was contributed by heating, ventilation, and air-conditioning (HVAC).
With increasing emphasis being placed on energy efficiency, the enhancement of vapor compression system performance is receiving much attention due to their high level of energy intensity.
DSIMAC simulation platform serves the needs. One can utilize the tool to build any kind of system model of air conditioning quipments and integrate it with conditioned space. Analysis with variable ambient temperature, part load, and etc. can be easily performed with the tool.
A system consisting of four key components is very popular unit for residential building. The residential air conditioning or heat pump with variable speed compressor and EXV is also gaining interest because of high efficiency at part load, comparing with tranditional on/off at poart load. Below is a simulation of such kind of air conditioning unit but with steady state PI control on evaporator superheat.
Variable refrigerant flow (VRF) airconditioning systems are also gaining in popularity to condition residential and commercial buildings. As component-based tool, DSIMAC simulation platform can easily help engineer to develop any VRF system and perform analysis.
DSIMAC simulation platform can also help engineer to build chiller system, from traditional system with shell-tube, to screw chiller with flooded heat exchanger, to centrifugal chiller with flooded or falling film heat exchanger..
Variable refrigerant flow (VRF) airconditioning systems are also gaining in popularity to condition residential and commercial buildings. As component-based tool, DSIMAC simulation platform can easily help engineer to develop any VRF system and perform analysis.
Since DSIMAC is designed as component-based tool with friently user interface, it can be easily adapted to growing complexity in vapor compression system.
Application examples of the modeling platform is focused on system analysis of three types of air source heat pump (one stage without injection, one stage with injection and two stages with injection).
