Study on regional applicability of dehumidification air conditioning system with different stage regeneration modes

Abstract

This article also put forward staged-regeneration wheel of the air conditioning system with condensing heat recovery technology, according to the climate zones in China, using the DesT software simulation in different areas of thermal and moisture load in a villa, and regeneration of the runner desiccant air conditioning system performance calculation, the results show that the compared with the two area runner desiccant air conditioning system, hierarchical regeneration runner desiccant air conditioning system performance are improved, the system of the refrigerant mass flow is reduced, the cooling load of the evaporator is reduced, the total load also significantly reduce energy consumption, air conditioning systems exergy efficiency improved; For regions with low temperature, low humidity or moderate humidity, the desiccant air conditioning system of three-areas graded regeneration wheel is more energy saving. In temperature and humidity relatively moderate areas, classification of renewable energy saving effect of the wheel were similar, but the four-areas wheel exergy efficiency obviously is higher than other wheel; For regions where both temperature and humidity are relatively high, the energy saving of the air conditioning system of the rotary wheel in the three-areas is not obvious, and the energy saving effect of the two-stage rotary wheel is the most significant.
