Description

Air-conditioning method and device thereof with interior air water cycle passive cooling
Affiliated technical field
The present invention relates to the HVAC technical field, be a kind of air-conditioning method and device thereof with interior air water cycle passive cooling, be applicable to the air conditioning, particularly its application in all kinds of buildings in xeothermic area in rooms such as all kinds of residential architectures, public building and industrial building.
Technical background
Point out in " the public building energy-saving design standard " of China's issuing and implementation in 2005: Chinese architecture is with surpassing 1/4 of national total energy consumption, and will progressively be increased to more than 1/3 along with the raising of living standards of the people, and in energy for building, the energy consumption of HVAC has accounted for about 27.4% again, therefore it is energy-conservation to vigorously advocate HVAC, for construction resource-conserving, environmentally friendly low-carbon type society crucial effects is arranged.
The refrigeration duty that air-conditioning equipment is born summer mainly is made of refrigeration duty and new wind load three parts that the heat production of refrigeration duty, unit of air-conditioned room own need be eliminated.According to different areas, different meteorological conditions, different appointed conditions, and the difference of building enclosure, the shared refrigeration duty ratio of three parts is different, but air-conditioned room the refrigeration duty of thermosetting is the major weight part, must cause sufficient attention.And total refrigeration duty in room is by constituting with the lower part: 1, the radiating and humidifying amount of personnel, indoor electric appliance equipment; 2, the solar radiation of window gets the refrigeration duty of thermosetting; 3, retaining wall, roofing etc. are by the refrigeration duty of heat conduction, convection current formation; 4, outdoor new wind is by the refrigeration duty of door and window infiltration formation.
(1) the energy saving analysis of window and sunshade mode
According to related data, in architectural exterior-protecting construction, the energy consumption of door and window is about 4 times of body of wall, 5 times of roofing, more than 20 times of ground, accounts for 40% to 50% of architectural exterior-protecting construction total energy consumption.Therefore, strengthening the thermal and insulating performance of door and window, reduce the door and window energy consumption, is the important step of improving the indoor thermal environment quality and improving the building energy conservation level.
For the architecture indoor environment, solar radiant heat is crucial outer disturbing, and in building enclosure, exterior window has tangible influence to the air-conditioning refrigeration duty.Because the heat transfer coefficient of glass is much larger than nontransparent building enclosures such as body of wall and roofs, the air-conditioning refrigeration duty proportion of its formation is much bigger, according to statistics, the heat that runs off by window accounts for 46% of building energy consumption, and the insolation that sees through glass gets hot refrigeration duty and accounts for 20% to 30% of air-conditioning refrigeration duty.Must cause sufficient attention.According to another relevant research, half of global residential architecture and non-residential structure refrigeration duty gets thermic load for solar radiation, and wherein the solar radiation by window gets the hot overwhelming majority that accounts for again.
Therefore, window is the weak link of building energy conservation, is the black hole of building energy consumption, is the main direction of control building energy consumption.
Comprise direct solar radiation and scattering radiation in the solar radiation through atmosphere arrival ground, and the architectural exterior-protecting construction outer surface comprises three from the aerial scattering radiation of accepting, i.e. sky radiation, ground return radiation and atmospheric long wave radiation.After generally (incidence angle<60 °) solar irradiation was mapped to surface of ordinary glass, 7.3% energy was reflected, can not become the room hot; 79% directly sees through in the direct inlet chamber of glass, all becomes the heat in room; Also have 13.7% and absorbed, and glass temperature is improved by glass.In absorbed this part energy, 4.9% will reach in the mode of long wave heat radiation and convection current again indoor, and remaining 8.8% be dissipated in the mode of long wave heat radiation and convection current equally outdoor, can not become the room hot.Therefore the reflectivity of glass is high more, and transmitance and absorptivity are low more, and it is just few more that the sun gets heat.
In order effectively to block solar radiation, reduce summer air conditioning load, adopting sunshading facility is means commonly used at present, according to the difference that the position is set, can be divided into external sunshade facility, internal sunshade facility, or between external sunshade facility, internal sunshade facility, blinds is installed in mode between the layer glass, be referred to as double-deck skin curtain wall.
Seeing through insolation in the windowpane inlet chamber gets and forms with these two parts of indoor heat (abbreviation absorbs heat release again) that the radiation mode of unifying is passed on a skill of craft to others again after indoor insolation of people (being called for short transmission insolation) and glass pane absorption insolation are directly advanced by penetrating window glass by hot system.
The internal sunshade facility can reflect away the part solar radiation, but can be returned by glass-reflected again to the part of external reflectance, makes reflex weaken.Internal sunshade just temporarily with the solar radiation thermal isolation beyond internal sunshade, but these radiations heat energies remove outdoor that part is reflected, major part is reentered indoor by abat vent and glass absorption back by modes such as radiation, convection current, all become indoor hotly, fundamentally do not reduce indoor air conditioner load;
The effect of external sunshade facility is better than the internal sunshade facility, but the external sunshade facility is exposed in the abominable external environment owing to external sunshade throughout the year, bear and expose to the sun and rain for a long time and capricious wind load, damage easily, in extraneous atmospheric environment, pollute the ability that the back reduces its sunlight reflection, not easy cleaning; The moulding of influence building, not attractive in appearance; Some sunshade measures had not improperly both reached effectively heat insulation, also can give to live and bring more inconvenience.
Double-deck skin window family curtain wall is in conjunction with the characteristics of inside and outside sunshade, employing is arranged on blinds between the layer glass, although eliminated the part shortcoming of external sunshade facility, but the air of meeting heating glass interbed owing to heat up in blinds heat absorption back, wherein the part heat can reduce its heat-insulating capability to indoor conduction, it is to take venting practice at the glass interbed that technology is arranged at present, by gravity-flow ventilation or force ventilation the heat of glass interbed is discharged to outdoor, so just can be so that its sunshading and heat-insulating effect more approaches the external sunshade facility.The shortcoming of its existence is that mainly air layer thickness is less usually between layer glass, causes air mass flow limited, and cooling-down effect is limited.Next is that the interlayer blinds still exists by incoming flow air-polluting problem, and the cleaning after polluting even more more difficult than external sunshade facility.Secondly the integral manufacturing cost is higher in addition, have difficulties with cooperating of building, and along with the difference of service time, the difference of sun altitude, the opening angle of blinds needs motorized adjustment mechanism, increases the cost of its initial cost cost and maintaining.
(2) the energy saving analysis of heating ventilation air-conditioning system
The required cold and hot amount of heating ventilation air-conditioning system produces the cold or heat-carrying working medium of carrying of back, output by thermal source and low-temperature receiver and is generally cold water or hot water, through distributing system to air processing machine or system's end, released cold quantity or heat.
For using maximum fan coil+fresh air conditioner systems in the architectural engineering, all be energy to be passed to the room that is conditioned finally, to reach desired indoor temperature, humidity parameter by wind system.What just fan coil was handled is indoor circulation wind, and new wind is the outdoor new wind of being introduced by air processing machine after treatment.
The new wind that air-conditioning system needs mainly contains two purposes: the one, and the concentration of dilution indoor harmful gas satisfies personnel's hygienic requirements, and the 2nd, the requirement of malleation in additional indoor exhaust wind and the holding chamber.In recent years, raising along with people's living standard, repeatedly the appearance of the Cure of Sick Building Syndrome incident that in traditional air-conditioning closed room, occurs, caused serious consequence, make people to indoor air quality with to the unprecedented concern of self health, cause air-conditioning resh air requirement in various countries' standards and norms that the trend of increase is arranged.
So just produced some problems, at first the increase of resh air requirement can increase building energy consumption undoubtedly, because the temperature of outdoor air will be higher than indoor circulation wind.Next is the balance of room air quantity, even if resh air requirement does not increase, a certain amount of new wind is sent into, and from the room air balance, must have the air draft of equal number to discharge, otherwise new wind can't normally be sent into the room.Therefore to requiring air-conditioning system that new wind must be arranged on some function of use, or the new wind air system that dry air can sweat cooling, how to drain the new wind that enters into air conditioning area?
Following several situation is arranged usually:
1, not having utilization drains.If resh air requirement is little, can adopt the method for nature malleation, discharge from the slit of door and window.
2, the new wind that will drain is collected air intake with new blower fan and carry out heat exchange and carry out energy and reclaim, but the pipeline complexity, investment is big, energy consumption is high.
More than the discharge mode of new wind behind the air supply air-conditioner room of two kinds of routines, first kind of mode do not recycled the energy of new wind, the situation that has the low-grade energy waste, owing to need the extra heat transmission equipment that increases, there are problems such as investment and space cooperation in the second way.
Therefore, from controlling stable indoor air environment, concerning construction style and building enclosure, control necessarily requires building enclosure that building is realized the isolated comprehensively of indoor and outdoor comprehensively, no matter is that natural lighting, air penetration or heat are transmitted.The thoroughly isolated of indoor and outdoor just can effectively be regulated and control indoor each physical parameter, and comparatively speaking, needed energy resource consumption is also just few more, energy-conservation more.Yet improvement from environment, at first to pursue natural lighting, gravity-flow ventilation even concerning the heat transfer property of building enclosure, some region also wishes sometimes that from climatic characteristic building enclosure becomes " energy-transmission channel " inside and outside the junction chamber, and two kinds of such theories will be pursued diverse construction style and building enclosure form.
In sum, window is the weak link of building energy conservation, the principal element that the indoor cooling and heating load that causes increases still, yet there are no the needs that can satisfy the room air adjusting all the time and can reduce the low method of energy consumption and cost and the report of device thereof again significantly.
