Building energy analysis tools are available in many forms that provide the ability to address a broad spectrum of energy-related issues in various combinations. Often these tools operate in isolation from one another, making it difficult to evaluate the interactions between related phenomena and interacting systems, forcing oversimplified assumptions to be made about various phenomena that cou...

The PV/T-GSHP heating control system is proposed to address the energy consumption problem of building in northern China. By using TRNSYS establish an automatic model, heat pump start/stop, water supply temperature on load side tank, and high return can achieve purpose being saving, providing stable heating, heating. results show that has annual fluctuation range 0.01~0.17 kW period for a typic...

Aiming at optimizing the energy consumption of HVAC, an conservation optimization method was proposed for HVAC systems based on sensitivity analysis (SA), named combination (SAC). Based SA, neural network and related settings about systems, such as cooling water temperature, chilled temperature supply air were optimized. Moreover, data existing system, various optimal control methods tested eva...

• Annual thermal performance of PTES in Dronninglund, Denmark monitored and analyzed. Trnsys model the developed validated against measurement 2015. The annual charged discharged energy were predicted with a deviation < ±4%. Ratio heat loss from cover, sides bottom respectively 60%, 38%, 2%. Influence soil types diffuser positions on investigated. Water pit storage is an effective long-term sto...
