The invention relates to a double-effect water chilling unit cold and heat combined supplying system. The double-effect water chilling unit cold and heat combined supplying system comprises a cold supplying unit, a heat supplying unit and a hot water bypass pipe and a cold water bypass pipe which are arranged between the cold supplying unit and the heat supplying unit; one end of the hot water bypass pipe communicates with a cooling water returning pipe, and the other end of the hot water bypass pipe communicates with a river water supplying pipe; and one end of the cold water bypass pipe communicates with a cooling water supplying pipe, and the other end of the cold water bypass pipe communicates with a river water returning pipe. Compared with the prior art, the hot water bypass pipe andthe cold water bypass pipe are arranged between the cold supplying unit and the heat supplying unit, when the refrigerating unit loads of the cold supplying unit and the heat supplying unit are matched, heat is supplied to a heat supplying refrigerator in the heat supplying unit through high-temperature cooling water return water in the cold supplying unit, cold is supplied to a cold supplying refrigerator in the cold supplying unit through low-temperature river water return water in the heat supplying unit, therefore, cold and heat combined supplying is achieved, the energy source utilization rate is increased, energy source waste is reduced, and the running economical performance is improved.
Description
technical field [0001] The invention belongs to the technical field of cold and hot water supply in factory areas, and relates to a combined cold and heat supply system of a double-effect chiller. Background technique [0002] The double-effect chiller system can perform heating and cooling at the same time to meet the water demand for hot water or chilled water for different terminal equipment in the workshop. Most of the existing double-effect chiller systems are divided into independent cooling units and heating units. There are multiple refrigerators in both the cooling unit and the heating unit. The refrigerators in the cooling unit utilize the The cooling water is used to prepare chilled water for end-use cold equipment; the refrigerator in the heating unit uses river water to prepare hot water for end-use heat equipment. This method not only requires a large amount of cooling water and river water sources, but also has a low energy utilization rate, resulting in seri...
