We experimented with the energy saving effect of applying a multiplex heat pump system and suggests a dissemination plan for new and existing educational facilities. The development and dissemination of a new system could reduce energy consumption by up to 57%, and help solve environmental issues. Experimental performance evaluated in the kindergarten to analyze the energy saving effect of the cooling and heating system. The average daily COP of the cooling and heating period in the field test was 3.79. Our results showed that the annual energy consumption was reduced, and proved that the multiplex heat pump system is effective in reducing energy consumption.
