Become the biggest energy dissipation.
Summary of the invention
The purpose of this utility model is to solve the skyscraper in the north in winter the asking of energy dissipation during heating
A kind of Zhongting heat recovery system utilizing Venturi effect inscribed and provide.
This utility model provide the Zhongting heat recovery system utilizing Venturi effect include upper spacer, lower clapboard,
Venturi tube, air delivery duct and air-return duct, wherein upper spacer and lower clapboard are located at the neutral surface position of building Zhongting, several also
The Venturi tube of connection is laid in the cavity between upper spacer and lower clapboard, and upper spacer and lower clapboard are provided with opening, opening
The inlet and outlet of position correspondence Venturi tube, Venturi tube middle part is further opened with vent, and vent is positioned at upper spacer
With in the cavity between lower clapboard, air delivery duct is located at the border of Zhongting, the opening of air delivery duct is positioned at the top of Zhongting, and air-return duct sets
In both sides, Zhongting bottom, the bottom of Zhongting is provided with radiation floor, and radiation floor bottom is provided with air channel of turning back, and air delivery duct is by turning back
Air channel is connected with air-return duct, and the air outlet of air-return duct is connected with the cavity between upper spacer and lower clapboard.
Air delivery duct and air-return duct outer wall are equipped with thermal insulating warm-keeping layer.
Operation principle of the present utility model:
In winter, there is bigger hot pressing in building interior, under hot pressing function, depth of building centre position will appear from neutrality
Face, meanwhile, under the effect of hot pressing, the following outdoor air of neutral surface enters indoor, and the above room air of neutral surface is by discharge chamber
Outward, entering indoor cold air and raise through indoor radiating equipment temperature after heating, density diminishes, along building vertical space
Floating, will form bigger ascending air (incident air quantity) at the Zhongting of building, under construction front yard neutral surface be disposed about equipped with
The upper spacer of Venturi tube and lower clapboard, this ascending air is when Venturi tube in parallel, due to the existence of Venturi effect, literary composition
Venturi middle part air velocity accelerates, and will form bigger negative pressure, and under the effect of this negative pressure, Zhongting top hot-air (draws
Penetrate air quantity) through air delivery duct, turn back air channel and in cavity that air-return duct is back between upper spacer and lower clapboard, in flow through venturi
Between return Zhongting headroom after the injection of position, and Zhongting top hot-air (injection air quantity) is at the radiation floor through bottom
Time, rejecting heat to radiation floor, after radiation floor heats up, heat passes to room air in the form of radiation.
The physical dimension of Venturi tube with injection air quantity with incident air quantity ratio as 1:2, Venturi tube middle part is formed
It is required that negative pressure be enough to overcome injection air quantity to decline through air delivery duct, air channel of turning back, air-return duct, dividing plate interlayer resistance consumption and hot-air
The buoyancy lift overcome is design considerations.
The beneficial effects of the utility model:
The system structure that this utility model provides is simple, without exterior power, realize Zhongting headspace heat recovery sharp
System, can be effectively improved the comfort level bottom Zhongting, reduce the heat dissipation equipment load on Zhongting ground, save the energy and disappear
Consumption.
