Through simulating the process of energy storage heating floor contain phase change material (PCM), the action and function of PCM in building energy storage are discussed. Analysis and numerical simulation the energy storage process in building structure with PCM packaging module, discussion the relation of temperature distribution, heat condition, energy storage and discharge time and PCM efficiency...
In this paper, the heating system with distributed variable frequency pump is analyzed. As the theory of dynamic distributed heating system improves gradually, which controlled by climate compensator, and for its great capacity of energy-saving, more and more heating systems become to use it, especially in the improvement works. In the paper, the author analyses how to design the system and the factors...
The heating system with distributed variable frequency pump is a heat-supply system in which the flow rate is regulated with return-water pressured pumps, instead of valves, set at return water pipe on the high-temperature side of heat exchange in substation. As the heating system has no valves to consume energy, much energy is saved. In this paper, the factors that the position of pressure difference...
The system of gas engine-driven heat pump (GEHP) combined cooling heating & power can provide the electric power for other equipments of building ,and is now one of the main directions that develop of power supply of distribute type energy system. This text analyzed the energy efficiency of GEHP at different combined supply energy modes. Simulation computes the relation to the Primary Energy Ratio...
