Abstract:

Taking an office building adopting temperature and humidity independent processed system with fan coil and outdoor air in Beijing as an example, under the cooling condition in summer, presents three schemes of using total air heat exchange and sensible air heat exchange to solve the problem of low supply air temperature in condensation dehumidification system. Through analysis of heat and moisture treatment process and calculation of energy consumption of each scheme, combined with the domestic energy saving design specifications, obtains the applicability of each scheme.
