英文要約Title: Research and Development of a Next-generation Heat Pump System/Research and Development of Innovative Energy-saving Controls of Next-generation multi split type air conditioning systems for buildings (FY2010-FY2012) FY2010 Annual Report
The purpose of our research and development is to improve the energy efficiency of multi split type air conditioning systems for buildings operated under low thermal load conditions and/or simultaneous cooling and heating. In order to accomplish this purpose, we develop an innovative energy-saving A/C controller and examine its energy-saving effects by the numerical simulation, partial thermal load performance tests made by a testing apparatus, and field measurements of its actual operating states in a real building. This new A/C controller consists of the real-time prediction of the indoor thermal load, the optimization of the capacity of A/C to the predicted thermal load and the minimization of the capacity control loss in simultaneous cooling and heating operations. In this year, we at first selected a model building that was adequate to evaluate the energy-saving effect of the newly developed A/C operated with this new controller, and calculated the annual variations of the thermal loads in it by using the simulation software. Next, the operating states of the new and conventional A/Cs were simulated numerically based on the controller models of the tested A/Cs and the thermal load model of the building. As a result of this simulation, it was ascertained that the newly developed energy-saving controller worked well and could attain 150% higher annual average COP in comparison with that of the conventional controller. In addition to these simulations, we conducted the partial thermal load performance tests of the new and conventional A/Cs for outdoor-air processing by using the air-enthalpy testing apparatus. This testing apparatus can reproduce the actual operating conditions of A/Cs equipped in a building. Based on the data of A/Cs measured by these tests and the meteorological data of the city in which the model building is located, the energy-saving effect of the new A/C was examined. The annual energy consumptions and annual average COPs of the tested A/Cs agreed quantitatively with the results of the above-mentioned simulation, and we confirmed that the new A/C controller brought about the desired energy-saving effect in A/C for outdoor-air processing. Moreover, as a preparation for the measurements of the actual operating states of A/Cs equipped in the model building, we compared the capacities of the new A/C measured by the air-enthalpy method with those predicted by the compressor-curve method. The compressor-curve method is adequate to the in-situ measurements of the capacities of A/Cs operated in a real building, and will be used in the research in the next two years. It was confirmed that the time-averaged capacities predicted by the compressor-curve method agreed with those measured by the air-enthalpy method within errors of 5%. This suggests that the compressor-curve method can be applied to the measurements of the actual operating states of A/Cs equipped in the model building with high reliability.
