Energy-saving assembly type building integrated system

Abstract

The invention provides an assembly type building integrated system which comprises a heater and an assembly type building, the heater is communicated with the assembly type building, air is heated in the heater and then fed into the assembly type building, hot air coming out of the heater is divided into two paths, one path enters the building, and the other path enters a thermodynamic system; the thermodynamic system comprises a heat exchanger, a horizontal baffle is arranged in the heat exchanger, the baffle extends out of the whole cross section of a shell of the heat exchanger, the baffle is arranged between the spraying device and an air inlet of the heat exchanger, fluid holes are formed in the baffle, and air flows upwards through the fluid holes. Meanwhile, water flows downwards from the lower part; from the lower portion to the upper portion, the distance between every two adjacent baffles is increased firstly, and then the distance is continuously decreased at a certain position. By arranging the heat exchanger baffles at intervals, the countercurrent flow heat exchange effect between the heat exchangers is better achieved, the heat exchange efficiency between the two inlets is the highest, the heat exchange time is the longest, the heat exchange effect is better compared with the normal countercurrent flow heat exchange effect, and the heat exchange efficiency can be further improved.

Description

technical field [0001] The invention belongs to the technical field of heat exchange, energy saving and environmental protection, and relates to an integrated system of an assembled building 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 storag...

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
