Abstract

A low-temperature air supply opening is characterized in that the low-temperature air supply opening is formed by connecting an air supply opening body (1), LED lamps (4) and an even heating cavity (6) with a capillary core together through a common copper pipe (2) and a heating pipe (5) with a capillary core; and the even heating cavity (6) with the capillary core is arranged on the backs of the LED lamps (4), and the metal copper pipe (2) is embedded into the position of a guide vane of the air supply opening body (1). A heating pipe condensation section is embedded into the guide vane of the low-temperature air supply opening, the outer surface of an air channel and other places where moisture condensation is easy, and an evaporation section is pasted to the heating faces of the LED lamps. The problem that emitted heat of the LED lamps cannot be discharged, and consequently the service life is influenced is solved, and the problem of moisture condensation of a low-temperature air opening is solved.

Description

A kind of temperature air blowing inlet
Technical field
The heat distributed when LED is run by the present invention is used for preventing temperature air blowing inlet from condensing, and belongs to the innovation and creation of building energy saving field.
Background technology
The principle that the 7.3.5 article design defining all-air air conditioning system according to " civil buildings heating ventilator and In Air Conditioning Design specification " (GB50736-2012) should meet: (1), in addition to technique particular/special requirement, should use single air-line system;(2), when conditioned area allows to use bigger supply air temperature difference or indoor moisture dispersed amount bigger, primary-air recirculating system should be used;(3) require to use less supply air temperature difference, and when indoor moisture dispersed amount is less, relative humidity allowable fluctuation range is bigger, secondary return air system can be used;(4) in addition to humiture fluctuation range requires strict room, should not there be heating and cooling procedure in same air treatment system simultaneously.According to (4th) article specify the attached provision explanation of this specification: generally, in addition to humiture fluctuation range requires strict room, same air treatment system should not have heating and cooling procedure, because heat cancels each other, does not meets energy-conservation principle.Visible, code requirement is not allow for thermal process again, then the air themperature at air outlet will be the lowest, and majority is less than dew point temperature, therefore, the air outlet of this system is easy to dew condensation phenomenon occur.This is the phenomenon avoided.
The summer of the conditioned area of the 7.2.2 article regulation according to " civil buildings heating ventilator and In Air Conditioning Design specification " (GB50736-2012) calculates heat and should determine according to the following: (1) passes through the heat that building enclosure is incoming;(2) the solar radiation heat entered by exterior window;(3) heat gain from occupant;(4) heat gain from lighting;(5) heat dissipation capacity of equipment, utensil, pipeline and other internal heat resources;(6) food or the heat dissipation capacity of material;(7) heat that penetration air is brought into;(8) amount of latent heat produced with various wet dissipation processes.As can be seen here, (4th) article of heat gain from lighting is intended to offset by air conditioning system.If the heat that luminaire distributes can be used for overcoming the low temperature condensation trouble of air outlet, then both achieved the direct counteracting of cold and hot energy, additionally it is possible to solve the low temperature condensation trouble of air outlet.Therefore, the device temperature that the heat dissipation capacity of luminaire is effective to lifting air outlet is the technology of non-the normally off key.
The scheme of temperature air blowing inlet anti-condensation at present has: (1) uses the insulation air port that thermal resistance is bigger;(2) induced draught air port is used;(3) flannelette is added on air port.Making a general survey of the scheme of these several anti-condensations, all less than solving problem on the source how avoiding condensation, but the mode judged the case as it stands solves.The present invention plans the heat that the bigger LED of the conventional caloric value of room lighting distributes and causes air outlet by heat pipe.Heat pipe condenser section is embedded in the place of the easily condensation such as the stator of temperature air blowing inlet, air channel outer surface, and evaporator section is affixed on LED heating face.The most not only can solve the condensation trouble of temperature air blowing inlet, it is also possible to improve the wind pushing temperature (improving this wind pushing temperature naturally to need not additionally reheat) sending into room, improve thermal comfort.Simultaneously as the waste heat of LED is well passed away, the life-span increases.The too low meeting of wind pushing temperature makes blowing feeling strong, and discomfort raises, and this is also the most again to add reheating process in air-conditioning processing system to promote the reason of wind pushing temperature.
Therefore, it is badly in need of a kind of anti-condensation temperature air blowing inlet by self regulation at present, adapts to new code requirement, meet requirement of engineering.
Summary of the invention
The heat distributed when LED is run by the present invention is used for preventing temperature air blowing inlet from condensing, and belongs to the innovation and creation of building energy saving field.
The basic ideas of the present invention are: by heat pipe, the heat that LED bigger for the caloric value commonly used in interior illumination fixture distributes is caused air outlet.Heat pipe condenser section is embedded in the place of the easily condensation such as the stator of temperature air blowing inlet, air channel outer surface, and evaporator section is affixed on LED heating face.Heat LED distributed by heat pipe passes to temperature air blowing inlet, promotes the temperature of air outlet, prevents the generation of dew condensation phenomenon, simultaneously as the heat of LED distributes timely, and life.Therefore, solve the condensation trouble of temperature air blowing inlet and LED owing to heat distributes bad and that the life-span is shorter problem.
The technical solution used in the present invention is: a kind of temperature air blowing inlet, it is characterized in that this temperature air blowing inlet is linked together with the band capillary wick soaking chamber being placed in LED back by common copper pipe and band capillary wick heat pipe by air outlet and LED to constitute, metal copper pipe is embedded in the gate positing of air outlet.
The invention have the advantage that this temperature air blowing inlet not only solves the condensation trouble of self, also solve the problem that LED is bad owing to heat distributes.Heat LED distributed passes to temperature air blowing inlet by heat pipe so that the temperature of temperature air blowing inlet raises, it is to avoid the generation of dew condensation phenomenon, meanwhile, can improve wind pushing temperature, reduces the too low human body discomfort caused of wind pushing temperature.The waste heat that LED distributes is distributed timely, and the life-span can extend.
It addition, this temperature air blowing inlet uses the building of LED illumination in a large number for some, such as, school, market, office building etc., effect is the most prominent.This invention just solves LED heat radiation row and does not goes out and affect the problem in life-span and problem that cold air diffuser condenses, has practicality and popularized type.
