Abstract:

The operational principle of CO2 transcritical cycle in the integrated air conditioning system of CO2 transcritical cycle with temperature and humidity independent control is introduced. And the theory analysis and simulation for the system is done by establishing the corresponding mathematics physical model. At the same time, using 100 kw refrigerating quantity as an example, simulation is made on the system combining with Coolpack. Simulating vaporization temperature TE, gas cooler outlet pressure P, gas cooler outlet temperature T4 of CO2 transcritical cycle, the influence of the simulated result is discovered. The study can provide theoretical support for the application of CO2 transcritical cycle with temperature and humidity independent control

Key words: CO2 transcritical cycle, temperature and humidity independent control, mathematics physical model, Coolpack, simulation
