Abstract: For the climatic feature of the Yangtze River Delta rigion, designed a constant temperature and humidity air-condi
tioning system driven by ground source heat pump with condensing heat recovery. Established mathematical model of constant
temperature and humidity air-conditioning respectively for ummer and spring, and carried the theory calculate and analyse on
constant temperature and humidity air-conditoning s stem driven by ground source heat pump with condensing heat recovery and
that with conventional electric heating. The results show that the recovery condensing heat of constant temperature and humidity
air-conditioning system driven by round source heat pump with condensing heat recovery enough to heat the air had cooled and
dehumidified to the required emperature range, which can reduce energy consumption by 40. 2% in summer and 77.4% in spring
compared to constant temperature and humidity air-onditionin s stem driven by ground source heat pump with conventional elec
