Abstract
A double-side adhering jet air supply method is provided. An air supply port is arranged on the ceiling of the room near by wall corner, the distance between the air supply port and the two side walls of the wall corner is as short as possible, and an air return port is arranged on the ceiling far away from the air supply port. The invention utilizes double-side adhering jet air supply method to reduce the entrainment of the air supply to the indoor air, so as to improve the air quality and energy-saving effect of mix roof air supply. When the air supply port is closer to the wall corner of the ceiling, the adhering effect of the two side walls is enhanced, the jet stream for the air supply port can bring fresh air to the ground to form air pool phenomenon at the lower region of space where indoor staff takes actives, so as to achieve similar effects as displacement ventilation in aspects of air-flow organization and indoor temperature gradient, etc. The air supply method can be used for buildings that have relatively small space and are inconvenient to arrange lower air supply port. In addition, the method can be applied to upgrade energy saving system of the existing air-conditioning system.
Description
Technical field
The invention belongs to the central air conditioner system air supply mode, be specifically related to a kind of air supply mode of two-sided wall attachment jet.
Background technology
Indoor environment is human survival and movable important place, the time of city dweller every day 90% is spent in various indoor environments, indoor environmental quality and health are closely bound up, thereby indoor air quality more and more receives Chinese scholars and researcher's attention and concern to health effects.Compound ventilation at present is two kinds of different air current composition forms that extensively adopt in the air-conditioning system with replacement aeration.Compare with traditional compound ventilation, replacement aeration not only has ventilation effect preferably, but also can reduce air conditioning energy consumption effectively, because these advantages of replacement aeration, so it has broad application prospects.But because the structural limitations of being built is arranged in the air port of air-conditioning system,-a little occasions, be difficult to lower disposed replacement aeration air port at air-conditioned room, in addition, in the air-conditioning system of a large amount of existing commercial buildings, there is the system of very big ratio to adopt the mixed ventilation mode, when improving the transformation of air quality and efficiency of energy utilization at these systems, since big at the transformation difficulty of building structure, often can not directly use the replacement aeration mode instead.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, provide a kind of can reduce to blow entrainmenting of room air improved the air supply mode of the two-sided wall attachment jet of the air quality of hybrid top air-supply and energy-saving effect.
For achieving the above object, the technical solution used in the present invention is: the ceiling that air outlet is arranged in the room is near the place, corner, and the distance of the two sides side wall in air outlet and corner is as far as possible little, and return air inlet is arranged in the position of ceiling away from air outlet simultaneously.
Also be provided with the air outlet grid that makes air-supply deliver to the bottom, room along the two sides side wall on the air outlet of the present invention.
The present invention is directed to the top air-supply that conventional hybrid is ventilated, thereby air-supply is entrainmented a large amount of room airs and is difficult to satisfy people to indoor environment and requirements of saving energy, the air outlet of top air-supply is arranged in ceiling near the place, corner, utilizes two-sided wall attachment jet air supply mode to reduce to blow and entrainmenting of room air improved the air quality and the energy-saving effect of hybrid top air-supply.When air outlet is closer apart from the distance in the corner of ceiling, the attaching effect of both sidewalls will be strengthened, the jet of air outlet can be delivered to ground with under the fresh air, form air pond phenomenon at the lower area of indoor occupant activity, can reach thus with replacement aeration in aspect similar effects such as air current composition and the distributions of indoor temperature gradient.This air supply mode can be used for the building that some spaces are little, cloth deposits the air outlet inconvenience, can also be generalized to the aspects such as air conditioner system energy saving transformation of existing building in addition.
Description of drawings
Fig. 1 is an air port of the present invention schematic diagram;
Fig. 2 is that front view is arranged in air port of the present invention;
Fig. 3 is that vertical view is arranged in air port of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
Referring to figure, 1-3, the present invention is arranged in air outlet 1 on the ceiling in room near the place, corner, air outlet 1 is as far as possible little with the distance of the two sides side wall in corner, thereby make full use of the attaching effectiveness of place, corner two sides side wall, prolong the air-supply range and reduce to blow along the mixing of journey and room air, while return air inlet 2 is arranged in the position of ceiling away from air outlet 1.The grid adjustment of the air outlet 1 of this air supply mode by air outlet can realize that air-supply delivers to the bottom, room along the two sides side wall, in stroke air pond, room personnel activity zone, thereby improves the air quality in personnel activity zone.
Adopt the present invention that air supply mode in traditional mixed ventilation is improved to two-sided wall attachment jet air-supply, make the air of sending into be deposited on the bottom, room and diffuse to form the air pond, thereby form the higher workspace of thermal comfort, reach air current composition effect near replacement aeration, this air supply mode can improve the temperature of air-supply on the one hand, thereby improve the coefficient of refrigerating performance of low-temperature receiver, improve utilization efficiency of energy, in addition, this air supply mode can also improve the indoor air quality of the mode of conventional hybrid ventilation, improves the thermal comfort of building.
Claims (2)
1. two-sided wall attachment jet air supply mode, it is characterized in that: the ceiling that air outlet (1) is arranged in the room is near the place, corner, air outlet (1) is as far as possible little with the distance of the two sides side wall in corner, and return air inlet (2) is arranged in the position of ceiling away from air outlet (1) simultaneously.
2. two-sided wall attachment jet air supply mode according to claim 1 is characterized in that: also be provided with the air outlet grid that makes air-supply deliver to the bottom, room along the two sides side wall on the said air outlet (1).
