Phase-change energy-saving window with ventilation function

Abstract

The invention discloses a phase-change energy-saving window with a ventilation function, and relates to the technical field of windows. The phase-change energy-saving window comprises a multi-layer phase-change energy-saving window body, ventilation systems and a control system, wherein the multi-layer phase-change energy-saving window body comprises a window frame, common glass and coated glass,the multi-layer phase-change energy-saving window body is provided with four layers, and the four layers are the common glass, the coated glass, the common glass and the common glass sequentially fromoutside to inside, the common glass and the coated glass are both fixed to the window frame, an air layer is formed between the common glass on the outermost layer and the coated glass, a phase-change layer is formed between the coated glass and the common glass in the middle, the phase-change layer is filled with phase-change material paraffin, the ventilation systems are arranged at the upper part and the bottom of the multi-layer phase-change energy-saving window body, and the control system is arranged outside the multi-layer phase-change energy-saving window body and connected with the ventilation systems. According to the phase-change energy-saving window with the ventilation function, the glass window is improved through phase-change materials, multi-mode operation of the ventilation systems is combined, the heat utilization rate is increased, energy is saved, and the indoor air quality is improved.

Description

Technical field: [0001] The invention relates to the technical field of windows, in particular to a phase-change energy-saving window with a ventilation function. Background technique: [0002] With the rapid development of society and the improvement of people's lifestyles, building energy consumption is increasing year by year. At present, building energy consumption accounts for 40% of the total energy consumption of the society, and the energy consumption of building enclosures accounts for 60% to 80% of the total energy consumption of buildings. As an important part of the building structure, glass windows account for 20% to 40% of the energy consumption of the building envelope. Enhancing the thermal insulation of glass windows and improving their thermal performance is one of the key means to reduce building energy consumption. [0003] In recent years, the application of phase change material energy storage technology to building envelopes has become an important di...

Problems solved by technology

[0004] Although the phase change glass window has the function of phase change heat storage, because the heat release process of the phase change material is bidirectional, the energy is transferred to the indoor and released to the outdoor at the same time, resulting in the loss of stored heat

Secondly, most phase change materials have low thermal conductivity, and the heat storage and release time of phase change materials is too long

In addition, at present, the function of glass windows with ventilation function is relatively simple, and the air sent into the room is not processed. Although the air quality of the room is improved, it increases the indoor load.
