For ocean-going vessels sailing in different areas on the sea, the change of external environment factors will cause frequent changes in load, traditional ship air-conditioning system is usually designed with a fixed cooling capacity, this design method causes serious waste of resources. A new type of sea-based air conditioning system is proposed in this paper, which uses the sea-based source heat pump system, combined with variable air volume, variable water technology. The multifunctional cabins’ dynamic loads for a ship navigating in a typical Eurasian route were calculated based on Simulink. The model can predict changes in full voyage load. Based on the simulation model, the effects of variable air volume and variable water volume on the energy consumption of the air-conditioning system are analyzed. The results show that: When the VAV is coupled with the VWV, the energy saving rate is 23.2%. Therefore, the application of variable air volume and variable water technology to marine air conditioning systems can achieve economical and energy saving advantages.

With the development of urbanization, the building energy conservation has been paid more and more attention, and 50% to 60% of the power energy consumption—the energy consumption of air-conditioning be paid attention for people. Research about measuring and analysis on energy consumption of VAV air-conditioning system is described in this paper. A measuring and analysis solution has been implemented in the VAV Air-Conditioning laboratory of Xi’an University of Architecture & Technology (XAUAT). The satisfactory results are given.
