Fabricated building and control method thereof

Abstract

The invention provides a fabricated building. The fabricated building comprises a fabricated wall body, and the wall body comprises a transparent plate, a preheating pipe, a heat insulating layer, an outer load-bearing wall, a heat preservation layer, an inner load-bearing wall and a ventilation part; the transparent plate, the preheating pipe and the heat insulating layer are arranged on the outer surface of the outer load-bearing wall, the transparent plate is arranged outside the preheating pipe, the heat insulating layer is arranged on the inner side of the preheating pipe, and the heat preservation layer is installed between the outer load-bearing wall and the inner load-bearing wall; the ventilation part is arranged on the inner surface of the inner load-bearing wall; and an upper inlet of the ventilation part is connected with a heater, the preheating pipe extends from the upper portion of the wall body to the lower portion of the wall body, the preheating pipe is provided with a branch, an inlet of the branch extends into a room on the inner side of the wall body, and a fan is arranged at the inlet of the branch. According to the fabricated building, water collection, air energy recovery and air source power generation are integrated into a system for the first time, and thus an overall building integrated technical system is achieved.

Description

technical field [0001] The invention belongs to the technical field of heat exchange, energy saving and environmental protection, and relates to an assembled wall system and a heating and ventilation system thereof. Background technique [0002] With the continuous development of the economy and the massive consumption of energy, energy conservation has become a topic of global concern. Renewable energy such as solar energy, wind energy, and geothermal energy, and the utilization of industrial waste heat and waste heat have become the focus of research and development in various countries. However, these energy sources have Due to the characteristics of discontinuity and instability, the research on energy storage technology is particularly important. Heat storage technology is one of energy storage technologies, and an important part of heat storage technology is the design of phase change heat storage heat exchangers. A common phase change heat storage heat exchanger cons...

AI Technical Summary

Problems solved by technology

However, the equipment composition of the thermal system is relatively complex, and the initial investment cost is relatively high. The closed thermal system belongs to the form of indirect heat exchange, which cannot further condense and extract water vapor; the open thermal system absorbs the solution in direct contact with the air. Impurity particles will enter the absorption solution and cause solution pollution, which will lead to scaling or blockage in the pipeline, and the system reliability is poor

[0007] In view of the above analysis, there are the following technical problems in the prior art: the solar energy utilization efficiency of the integrated building wall is low, the space occupancy rate of the wall may be too large, and the assembly efficiency of the building structure is reduced, so it needs to be improved
