Description
Technical field
The present invention is the passive cooling technology that combines with ground source heat and heat pump, belongs to energy field and air-conditioning technical field.
Background technology
Passive cooling technology is a kind of more ancient natural air conditioner technology of using under construction, just comprises this thought in ancient building, to help to create comfortable surroundings in the building.Passive cooling is exactly to utilize the method for nature to cut off (be provided with wall, plant block etc.) or remove heat (ventilation, evaporation etc.) from building in summer.Application mode in building can be divided into four classes according to the difference of effective object: the first kind mainly is that the building roof is cooled off (the retaining roof is set, contains wet stock, adds a cover thermal insulation board, air layer etc. is set); Second class mainly is that building masonry wall is cooled off (space layer is set) in the middle of body of wall; The 3rd class mainly is that (sunshade, cascade etc. are set) cooled off in light transmission parts such as the window, glass curtain, balcony to building; The 4th class mainly is that the building indoor floor is cooled off (building basement etc.).
Compared with mechanical system by braking technique and to have advantages such as energy-conservation, environmentally safe.It is rising using in future architecture.But exist problems such as architectural exterior-protecting construction practice complexity, efficient are not high, influence building wet environment simultaneously, in modern architecture, use seldom, be still waiting research.
Why traditional passive cooling exists above outstanding problem, is difficult to use in modern architecture, on mechanism: mainly be to utilize air to take away the thermic load of building (mainly being the draught effect and the evaporation of nature).And reason such as the heat capacity ratio of air is less, the effect that determines this mode is to be difficult to high efficiencyly, and can't regulate control.And underground be a huge constant temperature field, if utilize the cold that stores in underground ground or the underground water, come the building enclosure of building is carried out passive cooling by the form of liquid coolants such as water, can be high efficiency and regulatable undoubtedly, concerning modern architecture, will overcome the too passive and inefficient defective of traditional passive cooling technology.This content is different from traditional approach: utilize source, ground cold by liquid coolant, and be coupled the mode of buildings exterior-protected structure being carried out passive cooling with earth-source hot-pump system more in case of necessity.
Summary of the invention
With the passive cooling technology that ground source heat and heat pump combine, it relates to a kind of air conditioning mode that utilizes the cold and hot amount in source, ground that the building closed structure is carried out passive cooling.This mode is achieved in that
By underground buried tube or get underground water, surface water etc., from the underground cold (or heat) of obtaining, by heat exchanger or directly send in the architectural exterior-protecting construction, unite use with heat pump and solar energy equipment in case of necessity, buildings exterior-protected structure is cooled off (or heating), reach building is realized passive cooling purpose.The refrigerating medium cooling system practices such as the water of buildings exterior-protected structure comprise body of wall, roofing and window, glass curtain etc.
The passive cooling practice on body of wall and roof: can in the structure sheaf of body of wall or in the top layer, water piping system be set, circulate by cold water and cool off (or heating) body of wall, and play passive cooling (or heating) and cut off the effect that the body of wall roof conducts heat.Also can use solar-energy wall and roofing, realize passive cooling building in the outside on body of wall and roof.
The passive cooling practice of glass curtain and window: bilayer or compound glass are set, between layer glass, establish water curtain capable of circulation, by source, the ground low-temperature receiver cooling forms that circulate, can in recirculated water, add the photonasty material simultaneously, when high light, play extinction or reflective effect; Water when winter or transition season between the emptying glass, filling are the effect that air layer plays abundant daylighting and insulation; Also can not emptying when being compound glass, realize forms heating with hot water circuit.In order to guarantee not make forms or glass curtain bear too high pressure, when being the window of multilayer or skyscraper or glass curtain, but layering is provided with heat exchanger, makes each layer be separated into independent water circulation system.
When the heating air conditioning of building uses earth source heat pump or water source heat pump system and solar energy equipment, also can with the use that is coupled of earth source heat pump and solar energy.Concrete coupling type of service can be according to practice of engineering design.
Principle: normally descending shallow-layer is a constant temperature field, temperature is about the 15-22 degree, and the indoor design temperature of air-conditioning is about 27 degree, so it is feasible utilizing underground low-temperature receiver that building is directly cooled off, in conjunction with the characteristics of traditional passive cooling, building envelope is carried out passive cooling, have the effect of direct partition thermic load, highly beneficial to creating balanced comfortable indoor environment, will be a kind of air conditioner surroundings system of high degree of comfort.Energy-conserving and environment-protective simultaneously, even the indoor air-conditioning system of cancelling other use fan to regulate the primitive form of peak thermic load and get back to.Necessity can be united use with earth source heat pump or solar energy equipment, becomes the refrigeration-heating air-conditioner and the heating system of can full load regulating.From the electricity consumption situation in the whole nation,, also be a very big adjusting for the peak consumption of summer air-conditioning electricity consumption.
Pipe laying can utilize the good heat conductive of building enclosure to be used as the air conditioning terminal system in the body of wall roof, uses as end, has saved fan coil etc. and has not held equipment.The energy-saving wall that has outer insulation especially utilizes body of wall to use very suitable as end.
The heat absorption principle of water curtain window: water has very strong absorption to IR, and visible light accounts for nearly 50% in the energy of sunshine, infrared ray accounts for nearly 50%, ultraviolet ray accounts for sub-fraction, can absorb ultraviolet ray and infrared ray greatly by water and glass, and, modulability is arranged very much to effectively and reasonably eliminating the solar radiation thermic load by adding the absorptivity that photoactive substance can be regulated visible light in the water; Be double glazing winter behind the unwatering, plays the effect of effectively heat insulation and abundant printing opacity; Also can not emptying when being compound glass, realize forms heating with hot water circuit.Make the building forms can not only play the effect that reduces air-conditioning (or heating) load, also play cooling (or heating) and act on when water curtain temperature lower (or higher) indoor; Can also play insulation effect and neither influence daylighting winter.Be that the mode that other employings are filmed is beyond one's reach: though northern area adopts low emissivity glass favourable winter, also reduced the sunlight transmitance, and be disadvantageous to summer air conditioning load.The reflective coating film of southern area does not have modulability, and has destroyed indoor natural light environment.
Feasibility: northern area, thermic load total for building is greater than total refrigeration duty, so heat is that the guarantor is expensive, to the underground heat that stores is the operation that helps earth source heat pump, and passive type cooling help summer to underground heat storage, particularly the combined solar system more can give full play to the effect to underground energy-accumulation, avoided northern area load unbalanced, and caused long-term use to utilize ground source heat can make underground temperature field unbalance partially because of summer in winter.Simultaneously also can replace air-conditioning system, remove or reduce the cost of air-conditioning system from.Southern area, underground water and earth surface water source are abundant, and for the passive cooling in source, ground provides condition, and south can directly be used for heating when underground water temperature higher (more than 20 degree), or cooperates heat pump to heat the back on a small quantity to heat.
