(1)研究開発の内容と取り組みの概要
業務用空調用エネルギーの面的利用に関しては、地域・建物・室内環境といった範囲(レベル/スケール)が異なるシステム別に省エネ評価が行われている状況にあるが、実際には、地域内の空調に係るあらゆる構成要素(機器)間のトレードオフを踏まえての、網羅的なシステム統合が望まれる。
英文要約Annual Progress Summary in 2012
“Next generation Heat Pump System Development
/ Development of High Density Cold Energy Network”
Commissioned by Tokyo Denki University, Tonets Corporation.
1. BACKGROUND OF DEVELOPMENT
To enhance an air-conditioning efficiency with the heat pump system, especially for office buildings which requires whole year cooling in Japan, not only enhancement of heat pump section but also enhancement of cold energy transportation section is very important. On this commission, as for the fundamental study on “next generation heat pump system”, we proposed the development of "High Density Cold Energy Network" to contribute to efficient energy use in the near future.
2. CONCEPT OF HIGH DENSITY COLD ENERGY NETWORK
This proposal covers entire systems for air-conditioning in the area. As for the District Heating and Cooling (DHC) system, utilizing the ice character which is higher energy density than water enables efficient energy transportation. As for the building system, utilizing the lower temperature of ice enables efficient operation of water pumps and air-conditioning fans. Also as for the indoor condition, utilizing the lower temperature of ice enables lower humidity condition. Therefore, from the view of the thermal sensitivity of residents, the set value of cooling temperature can be set to higher, and it also contributes to the reduction of cooling load. In addition, "High Density Cold Energy Network" which enables the cold energy communication between buildings realizes more efficient energy use for air-conditioning.3. POINTS OF DEVELOPMENT
For this proposal, three of subtasks set up. Subtask 1 is requirements verification for the "High Density Cold Energy Network". Subtask 2 is engineering development of to get ice into the main piping of DHC. Subtask 3 is engineering development of piping system. Subtask 4 is to develop the integrated controlling system which covers from DHC (ice generation) to indoor air-condition (destination of cold energy).
4. ACHIVEMENTS SUMMERY IN 2012
On this year 2012, followings were shown. The estimated results which were set initially were almost achieved. However, by the Tohoku Earthquake, some items were not able to experiment too much enough. Therefore, hopefully, more time should be spent for reliable system development in the future.
Through the development of system simulation program, the method of controlling the system became clear. On the other side, through the design and constructing phase of experiment system, we compiled the design method and basic data.
