Abstract—The dynamic performance of a novel
variable-speed ground-coupled liquid desiccant air-conditioner
(VSGCLDAC) was analysed and compared with that of a
conventional constant-speed ground-coupled heat pump
(GCHP) in to the subtropical climate of Hong Kong. It was
found that both the borehole length and the total energy
consumption were reduced substantially. For the case of a
multi-storey building, the VSGCLDAC could generally serve
one more floor as compared to the GCHP system. Together
with the enhancement of the indoor air quality, the
VSGCLDAC was demonstrated to be a good choice for use in a
low-rise building.
Index Terms—Borehole ground heat exchangers,
ground-coupled heat pumps, liquid desiccant cycle,
variable-speed control.
