Title Solar cogeneration systems design of small villa in Lianyungang
Abstract
Building energy consumption is an important part of the total energy
consumption in our society. The combination of CHP system with heat pump
and constructions can not only popularize the renewable energy which
represented by solar energy, but also decrease the energy consumption of
constructions and optimize the energy structure of china.
In order to achieve the goal of using renewable energy as an energy supply
for a small villa in Lianyungang, this paper designs the Solar-CHP system
on the combination of environment parameters and users' demand, and
provides the layouts of system according to the structure of the villa.
The main work is summarized as follows.
1）The apparatus of the system are calculated and then the equipment
selection are explained in this paper, and the design principles of
apparatus of the system and the selection basis of devices is elaborated；
2) The layouts of solar energy system in the villa is provided in this
paper；
3）An analysis of the economy of whole system is made；
4） The future of the combination of solar energy equipment and constructions
is prospected. Keywords building energy conservation，solar cogeneration，geothermal
heat pump，PV，solar hot water systems
