Definitions
- the present application generally relates to a device suited for preheating fresh outside air by means of free energy, such as solar energy and/or heat recovery.
- BACKGROUND ART Design of traditional glazed solar air heaters generally comprises a glass, polycarbonate or Lexan® transparent cover placed in front of a dark solar absorber.
- the front transparent cover is provided for minimizing heat losses from the top of the collector.
- Fresh outside air is traditionally admitted at on end of the collector between the front transparent cover and the solar absorber.
- the air passes through the collector along fins and absorbs heat from the solar absorber as it travels therealong. Warm or hot air is discharged at the opposite extremity of the collector.
- Heat loss happens through the bottom, the edges and the top (where the glazing is) of the collector.
- the edges and the bottom are insulated, so that heat loss mostly occurs through the top, that is by convection between the absorber and the glazing and then by conduction through the glazing. When the glazing becomes very warm, the collectors become less efficient.
- a heat collector comprising a transparent glazing exposed to the ambient, the transparent glazing being spaced from a back surface to define a plenum therewith, a plurality of perforations defined through the transparent glazing for allowing outside air to flow through the transparent glazing into the plenum, the perforations being distributed over a surface area of the transparent glazing, the plenum having an outlet, and air moving means to draw heated air from said plenum via said outlet.
- the back surface includes a solar radiation absorbing panel.
- a transparent and perforated surface exposed to the ambient.
- the perforated transparent surface is spaced from a back surface so as to define an air gap or plenum therebetween.
- Fresh outside air is drawn into the plenum through the perforated transparent surface.
- the back surface can, for instance, be provided in the form of a bottom of a solar collector, a building wall or roof, an outer surface of a greenhouse, a photovoltaic panel, the ground or any non-porous surface.
- the gap of air is maintained under negative pressure due to mechanical or natural means.
- An outlet is provided for allowing the air flowing through the plenum to be drawn into a duct or a channel, for use as makeup, ventilation, process or combustion air to a device which consumes or needs thermal energy.
- the air in the plenum is heated either by incident solar radiation on the surface of the back panel, which acts as a solar absorber, and/or by heat escaping from the back surface.
- the device can therefore act as a solar air heater and/or as a heat recovery unit.
- the back surface can be of a dark color, so that incident solar radiation passing through the perforated transparent surface is absorbed by the back surface in the form of heat and not reflected back to outer space.
- the back surface for any aesthetic reason or other, must be of light color, the solar thermal efficiency remains higher than other conventional unglazed collector design.
- the device is used as a heat recovery device, since the back surface can be of any color with no influence on efficiency (it can even be transparent like in the case of a greenhouse), but the lower the thermal resistance (insulation) of the back surface, the greater the heat recovery rate.
- the device can be simultaneously used for both functions of solar heating and heat recovery.
- the preheated air leaving the device can have an auxiliary heating device located downstream (e.g. a gas-fired system) to bring its temperature to a given set point.
- auxiliary heating device located downstream (e.g. a gas-fired system) to bring its temperature to a given set point.
- a method of preheating outside air for a building having a sun-facing surface comprising: providing on the sun-facing surface of the building a perforated transparent surface allowing solar radiations to pass therethrough, a plenum being defined between the perforated transparent surface and the sun-facing surface, drawing outside air through the perforated transparent surface into the plenum, capturing incident solar radiations passing through the perforated transparent surface, heating the air in the plenum using the captured solar radiations, and withdrawing the heated air from the plenum.
- Fig. 1 is a schematic side view of a solar collector including a perforated transparent surface in accordance with an embodiment of the present invention
- Fig. 2 is a schematic side view of another embodiment of a solar collector having a perforated transparent glazing
- Figs. 3 and 4 are schematic side views of ground-mount configurations of solar collectors having perforated transparent glazing in accordance with further embodiments of the present invention.
- Fig. 6 is a schematic side view of a roof mounted solar collector having a perforated transparent glazing
- Fig. 1 shows a solar air heater 10 provided in the form of an elongated conduit-like enclosure mounted on a base and including a sun facing perforated transparent glazing 12 exposed to the ambient and placed in front of a back panel having an arcuate solar radiation absorber plate 14 applied over an insulation layer 15.
- the back panel is generally provided in the form of a half-pipe wall covered with the perforated transparent glazing 12.
- the absorber plate 14 can be of a dark color to maximize solar gain.
- the perforated glazing 12 can be provided in the form of a perforated polycarbonate or transparent UV-resistant plate. Other transparent polymers could be used as well.
- the glazing 12 can be rigid or flexible.
- the perforations can be distributed over the entire surface of the glazing or over only a selected surface area thereof. The density of perforations can be uniform or variable over the glazing surface.
- the perforated glazing 12 and the solar radiation absorber plate 14 define a plenum 16 therebetween.
- a fan or other suitable air moving means 17 is operatively connected to an outlet 18 provided at one end of the back panel to draw fresh outside air through the perforated glazing 12 into the plenum 16 before being directed to a ventilation system, such as a building ventilation system.
- the solar radiations passing through the perforated transparent glazing 12 are absorbed by the absorber plate 14.
- the air in the plenum 16 picks up the heat absorbed by the absorber plate 14 before being drawn out of the plenum 16.
- the glazing 12 remains at a temperature substantially equal to the ambient temperature. Accordingly, the temperature differential between the incoming air and the ambient is equal to zero or close to zero, so that thermal efficiency remains at the highest possible value. Heat losses through the glazing cover are thus kept to a minimum.
- Fig. 2 shows a second embodiment in which like reference characters refer to like components.
- the solar air heater 10a shown in Fig. 2 essentially differs from the solar air heater 10 shown in Fig. 1 in that the solar air heater 10a has a planar configuration characterized by spaced-apart parallel transparent glazing and back panel.
- the back panel is provided in the form of a flat absorber plate 14a applied over a planar layer of insulation material 15a.
- the absorber plate 14a could be corrugated.
- Sidewalls or supports 19a are provided along the perimeter of the back panel and the perforated transparent glazing 12a in order to create a uniform air gap 16a therebetween.
- the perforated glazing 12a and the back panel are preferably coextensive.
- the back panel 14a can be provided in the form of photovoltaic (PV) panels to provide the double function of air heating and cooling the PV panels, which produce more electricity when their surface is kept at cool temperatures.
- PV photovoltaic
- the perforated transparent glazing 12a is preferably supported at an inclination equal to the latitude of a given location, and facing the equator, depending on use.
- the transparent glazing could be oriented and inclined otherwise.
- Fig. 4 shows a horizontally oriented perforated transparent glazing
- Fig. 5 shows a vertically oriented glazing.
- the solar air heater can be mounted directly on the ground, the ground surface forming the back panel of the device.
- the plenum 16b is formed by the perforated transparent glazing 12b, a building wall 20b and the ground G.
- the fresh outside air drawn in the plenum 16b is heated by the solar radiations absorbed by the ground G as well as by the heat escaping from the building through wall 20b.
- the fresh outside air flowing through the perforations defined in the transparent glazing 12b maintains the temperature delta across the glazing close to zero, thereby ensuring high thermal efficiency.
- the heated air is drawn out from the plenum 16b and circulated in the building B via the building ventilation system (not shown).
- the solar air heater can also be provided in the form of an enclosure having a perimeter wall 19c, a closed bottom end formed by the ground, and a top end covered by the perforated transparent glazing 12c.
- An outlet 18c connected to suitable air moving means is provided for withdrawing the heated air from the enclosure.
- the perforated transparent glazing 12d and 12e can be mounted in opposed facing relationship to a building wall 2Od or the roof 22e of a building.
- the plenum 16d is formed between the outside surface of the building wall 20d and the adjacent vertically oriented perforated transparent glazing 12d.
- the plenum 16e is formed by the outside surface of the building roof 22e and the perforated transparent glazing 12e.
- the heat escaping from the building envelope through the wall 2Od or the roof 22e is recovered to heat the air in the plenum 16d and 16e.
- the roof 22e and the building wall 20d both act as solar radiation absorbers to further heat the ambient air drawn in the plenums 16d and 16e.
- the solar radiations pass through the perforated transparent glazing and are absorbed by the underlying building wall or roof surfaces and the air in the plenum absorbs the heat from the building wall or roof.
- the transparent glazing does not negatively alter the appearance (i.e. change the color of the building wall or roof) of the building.
- the performance of the system is not influence or restricted by the color of perforated panels installed on the building wall or roof.
- the perforated glazing 12d and 12e are transparent and thus they do not change the color of the building wall or roof. No compromise has to be done for aesthetic purposes.
- Fig. 7 shows a further potential application of the present invention. More particularly, Fig. 7 illustrates a greenhouse B' having a skeleton framework covered with a transparent skin 25f or membrane, as well know in the art.
- a perforated transparent glazing 12f is mounted to the greenhouse wall and roof to define a double-walled structure including an air gap 16f defined between the perforated transparent glazing 12f and the inner transparent skin 25.
- the perforated transparent glazing 12f acts as a second insulation layer for the greenhouse B'.
- the heat escaping from the greenhouse through the inner skin 25 is recovered in the air gap 16f.
- a fan or the like can be provided for drawing heated air from the air gap back into the greenhouse B'.
- the perforated transparent glazing 12f maintains the required transparency required for plant growth.
- the device can be used in several applications including:
- Air-based heat pump air-to-air or air-to-water
- swimming pool heat pump Air-based heat pump
- the above described transpired or perforated glazing offers numerous benefits.
- the incoming air is admitted throughout the glazing surface, either on a large proportion of its surface or over the entire surface. Accordingly, the glazing surface remains cold so that collector top heat loss is substantially prevented.
- the proposed perforated transparent glazing design provides solar efficiencies at least as good as that provided by the perforated plate design at high flow rates. For lower flow rates, however, the solar efficiency remains high and by far exceeds that of opaque perforated collectors, and even exceeds that of glazed collectors, for less than half the cost. That can be readily appreciated from Fig. 8. More particularly, it can be seen that for flow rate between 2 and 6 cfm per square foot of perforated surface, the efficiency of a perforated glazing with a black backing surface is greatly superior to that a conventional black perforated sheet metal solar collector. The difference in performance is even more noticeable for light or white color solar collectors.
- the perforated glazing with a white color backing surface is up to 100% more efficient than a white perforated sheet metal collector. It can also be appreciated that the difference in performance between conventional unglazed perforated collectors and the above described perforated glazed designs is even more significant at low flow rates of, for instance, 3 or 4 cfm per square foot.
