For pool structure construction of water treatment engineering,if there’s no fully knowledge about the characteristics of pool structure,it’s very common to appear seepage or cracks to the structure or could not meet the performance requirements of frost resisting or seepage resisting due to improper construction measure,thus it could not promise a good durability of pool structure.

In recent years,solar hot water systems and building integration have become new development opportunity in this industry,some technologies related to solar hot water building integration were analyzed.

Combined with a villa project with the detailed installation plans of the heat collector,pre-buried components and the plan of pipes drilling through the roof,the practice of the separated-pressured solar water heater and building integration was described,and the gain and loss of the project were summarized.

Research on PV Module Encapsulation Technology of Building Integrated Photovoltaic(BIPV)System;

States that the building integrated photovoltaic and grid-connected generating technology will be the main fashion for solar energy utilization in densely populated cities.
