Abstract:
Presents the flow process of the device, which can cool the outdoor air to about 21 ℃ in standard outdoor design conditions of Shanghai in summer with the driven heat source of waste water below 70 ℃. Its cooling capacity is 70 kW, the COP is about 0.66 and the EER can reach 12.04. When combined with the CCHP system the cooling capacity can be improved by 18.8%.
