热泵冷热水联产在某工厂的应用

Application of Cold and Hot Water Cogeneration with Heat Pump in a Plant

某工厂利用高温热泵取代天然气锅炉后,每年可以节省天然气1 950 568 Nm^3,同时为冷源系统提供了大量冷量,减少了冷却塔散热5.3×10^(10)k J,全年节省标煤1 460吨。对于同时具有冷负荷和热负荷需求且冷负荷大于热负荷的场所,采用高温热泵系统来实现冷热水联产,具有广泛的应用前景。

Application of high temperature heat pumps instead of natural gas boilers in a plant could save gas by 1,950,568 cubic meters per year,reduce the heat emission by 5. 3 × 1010 k J,and save standard coal by 1,460 ton per year. The high temperature heat pump system are applicable to places where cooling load and heating load are needed at the same time and the cooling load is higher than the heating load to achieve hot and cold water cogeneration with prospect of extensive application.
