| Abstract: |
| A new type of chiller system relying on desiccant potential discharging was constructed based on the energy storage mode using liquor desiccant potential,which was able to provide cooling resource for air conditioning system and especially for radiant cooling air conditioning. The mechanism about the energy storage mode-using desiccant potential was explained. The influence of evaporative temperature,cooling water temperature,and liquor concentration on the normalized cooling capacity of the system was calculated and analyzed theoretically. The results show that the system could obtain chiller water for air conditioning under designated operation conditions and the high-normalized cooling capacity could reach 10 kW. In addition,the minimum temperature of the chiller water provided by the system depended on dew point temperature of the air after dehumidification. |
