摘要：

A combined system intended to be an alternative to provide cold and heat for buildings was set up. Energetic efficiency evaluation of the combined system of cold and heat is presented, where primary energy rate (PER) and comparative primary energy saving are used. Comparison of energetic efficiency of the combined prototype system with contemporary conventional separate systems of cold and heat shows that energy utilization efficient is improved greatly, and there is a large potential for energy saving by the combined system of cold and heat.
