Description

Method and devices for building cooling

The invention relates to the field of industrial, agricultural and civil constructions, namely, to the cooling of buildings by their facades and roofs, both in the construction of new buildings and in the reconstruction of previously exploited structures.

Most of winter energy losses and summer energy input occurs through the building cover (walls and roof). The most common method of cooling is ventilation.

Ventilation of facades and roofs is widely used to increase thermal insulation, indoor comfort, protect against weather conditions and improve aesthetic qualities.

To evaluate the novelty and technical level of the solution declared by the authors let's analyze the similarly designs of methods and devices known from the available information.

Ventilated facades are of different types, but generally have similar structures to those described in III. Building cladding elements are fixed to the wall by means of metal fasteners, longitudinal guides and vertical members. Thermal insulation is installed in contact with the wall. There is a vertical air passage between plates and thermal insulation layer that assures ventilation of the building.

Ventilated facades have been developed to protect buildings from the combined effects of rain and wind, limiting the negative effects of rain drops, keeping building dry, with aesthetic features and undeniable advantages in thermal and acoustic insulation.

The name "ventilated facade" comes from the use of the draft effect, realizing the natural ventilation of the facade, removing heat and moisture.

Ventilated facades reduce summer costs for air cooling and heating costs in winter.

Benefits of ventilated facades for buildings are: optimum solution combining thermal, aesthetics and water resistance; reduced time for preparing exterior walls surface; the brackets are easy to fix; installation is easy; good acoustics; easy to maintain.

Roofs are of a multitude types, but generally have similar structures to those described in 111. In spite of this, they have common elements, namely A-shaped rafters with pliers, installed on the ridge and purlins. Along rafters are installed the counter slats, which fix anti-condense foil to the rafters, and the slats are installed along rafters, on the counter slats. Counter slats together with anti-condense cover and the foil form ventilation channels. The drafting effect achieves natural ventilation of the roof, removing heat and moisture. Thermal insulation is installed inside, between rafters. The cover is made up of panels, finished with ridge and other elements. The author of 111 proposes plastic slats with transverse holes, which would allow to increased air flow and, as a result, would increase the building cooling.

Ventilated and thermally insulated covers reduce summer costs for cooling and winter heating costs, but they do not provide the necessary cooling of the premises in the building during summer, especially in the hot and dry regions, even having slats with transverse holes.

Traditional cooling systems are expensive and consume a lot of energy, the equipment occupies large areas in buildings, they need considerable space to install the air ducts. They lead to increased electricity consumption, for example by 15% in the state of California (USA) and in peak hours up to 30% 131. It creates discomfort for humans or animals in buildings that do not have such systems because the temperature is above normal. An efficient cooling is water evaporation from a wet surface. According to the results of the research /4/, the cooling yield of a flat (not moistened) ventilated surface is about 30% and a wet ventilated flat surface is almost 85%. The author of the research proposes a facade that contains two channels: one dry and one wet. The wet channel is located outside (sunny) and the dry channel - from the building wall side. The channels are separated by a porous sandy wall, glazed on the dry passage side. The porous wall is kept moist. A fan is located at the bottom of the device in the vicinity of wet and dry channels inlet and at the top - outlet of the humid channel into atmosphere. The dry channel is connected to the spaces in the building.

Maximum temperature drop with maximum cooling efficiency occurs at the maximum sunshine, minimal air humidity, minimal airflow speed. Cooling efficiency is determined as the proportion of evaporation cooling capacity to fan and water pump energy consumption. The maximum cooling efficiency in the described experiments exceeded 10. The cooling system is functional during day and night.

The method and means described in /4/ are based on the cooling of the indoor air of the building and function as follows.

The fan sends outside building air into dry and damp channels. It, moving along the wet pass, comes in contact with the water thin film on the porous surface of the wall and evaporates it. The surface cools due to water evaporation. The higher the outside air temperature, the greater is the evaporation intensity and the lower is the temperature of the porous surface. The air in the wet channel is loaded with water vapor and is thrown out through the top exit. Due to the cooling of the moist porous wall, the heat is transferred to the glazed and dry side and cool air. The air temperature in the cold and dry channel decreases and it is sent into the building's spaces through the top of the passage.

The method and means described has the following disadvantages.

The porous wall has a low thermal conductivity and poorly conducts heat from the moist channel to the dry channel. Long retention of water in it and high temperature leads to the appearance of microorganisms and mold, which jeopardizes the health of the building occupants. Special technology is required to produce porous material.

Using fans leads to additional electricity consumption, increased investment and maintenance costs. In addition, the electricity consumption is high because of its antigravity work: the air density increases as the cooling goes down and the fan forces it to move upward.

The disadvantage of the above described methods and means is that they are not comprised in a method and means with common properties, each of them having the described drawbacks. The problem solved by the present invention is buildings cooling during high outdoor temperatures and the preservation of indoor heat in the cold season of the year.

According to the invention, the building cooling process and its embodiments, which include ventilation of the envelope through the channels between the outer casing and the thermal insulation layer, the cooling of the air is achieved by spraying water into the cold and wet air channels formed by the cooled surface of the building and the surface of the thermal insulation layer and is extracted into the hot and humid air channels formed by the outer wall of the outer shell and the other surface of the thermal insulation layer being controlled by adjusting the transverse channel surfaces to the air inlet into the cold and humid air channels and its exit from the hot and humid air channels.

fig. 1 1 , vertical cross-sectional view of the device in the shape of whole-building with repression. The facade-shaped device comprises cold and humid air channels 1 (fig. 1 , 2), hot and wet air ducts 2, which are joined together at the bottom and form a passage. The cold and humid air channels 1 are formed by the vapor barrier 3 of the building wall 4 and one surface of the thermal insulation layer 5. The hot and wet air ducts 2 are formed by the exterior wall of outer finish 6 and the other surface of the thermal insulation layer 5. The outer finish 6 and the thermal insulation layer 5 are installed on support 7, which is fixed to the wall 4 by screws 8.

At the other end of the facade (top) the cold and humid air channels 1 (fig.3) and the hot and humid air ducts 2 are provided with flaps 9 and 10. The cold and wet air ducts 1 are equipped with water sprayers 1 1 fixed on the supports 12. The flaps 9 and 10 are controlled by means of the axle 13, which has the levers 14 and 15 connected by sliding with the flaps 9 and 10, which are pivotally connected to the support 7.

The roof-shaped device (fig. 4) comprises a cover 16 installed on the slats 17, which are in turn fixed to the counter slats 18. The anti-condense sheet 19 is installed between the rafters 20 and the counter slats 18. Counter slats 18, anti-condense sheet 19 and the cover 16 with the slats 17 form the hot and humid air channels 21. There are channels 22 between rafters. The rafters 20 are placed on the purlins 23 and ridge 24. The roof 25 is movable. From the inside (fig. 5) of the rafters 20 the inner finish 26 fixed on the slats 27 is placed.

The thermal insulation 28 is installed between rafters 20. The junction of the channels (fig. 6) 22 with the channels 21 is formed by the counter slats 18 through preformed channels 29 installed in the thermal insulation 28 on the purlins 23. The mouth of the cold and wet air channels 30 (fig.7), is installed on the ridge board 24, under the roof ridge, on which is installed the limb of positioning device 31 and the water sprayers 32.

Thus the cold and humid air channels start from the mouth 30 of the cold and humid air channels, continuing through the channels 22, the preformed channels 29, that connect the cold and humid channels 22 and hot and humid channels 21 and the top of them connect with atmosphere.

The ridge position control device 31 (fig. 8, 9) comprises small ridge 33 and large ridge 34. The small ridge 33 is fixed to the bar 35, on which a spring stop 36 is placed. The spring 37 is placed between the stop 36 and pipe 38. The bar 35 is slidably connected to the eccentric 39. The eccentric 39 is fixed to the common axis 40 for all eccentrics.

Device of building cooling in the shape of whole-building (fig.10) contains roof cover 41 , hot and humid air ducts 42 formed by the cover 41 and one surface of the thermal insulation layer 43. The hot and humid air ducts 42 are joined to the hot and humid air channels 44 formed by facade cover 45 and the vapor barrier 46 of the building wall 47. The roof 49 is movable (as in the case of the roof-shaped device). There is placed the vapor barrier 48 from internal side of the thermal insulation 43 of the roof, which, together with the intermediate wall 50, forms cold and humid air channels 51. There are ducts 52 at the bottom of building wall 47, which connect cold moist air channels 51 and hot and humid air channels 42. The hot and humid air channels 42 communicate with the atmosphere through the passages 53 and the cold and humid air channels 51 communicate with the atmosphere through the channels 54. Water sprayers 55 are installed in channels 54. Intermediate wall 50 forms with the inner wall 56 of the building cold and dry air ducts 57. The inner wall 56 includes air passages 58. The cool and dry air channels 57 are connected to the fan outlet 59. The used air is drawn through the air duct 60. The position control device 48 is shown in fig. 8, 9.

Device of building cooling in the shape of whole-building by discharge (fig. 1 1 ) contains the same elements as in the previous case (fig. 10) except that the channels 54 that are connected to fans 61 and the shaft 48 is not movable and not needs a device to control its position.

The process and devices work as follows.

In the hot weather, when the building needs cooling, (fig. l , 2, 3) the flaps 9 and 10 of the facade- shaped device opens by turning the axis 13. The lever 14 sliding on the flap 10 pulls and opening it and the lever 15 sliding on lever's anti-arm of the flap 9 also opens it and the air can freely circulate in the cold and humid air channels 1 and the hot and humid air ducts 2. The sprayers 1 1 , which spray water at the end of the cold and wet air channels 1. Water spraying considerably increases the contact surface of the water with air, which intensifies the heat extraction from it. Air in this area cools as a result of water evaporation, its density increases and drops down. At the same time, the air in the hot and humid air channels 2, being heated by the sun's rays through the exterior finish wall 6 or the ambient heat, rises upwards. As a result, vertical aspiration is formed in the hot and humid air channels 2. Air entering the cold and wet air ducts 1 , descends downstream of the sprayers 1 1, enters the hot and humid air channels 2, rises up and go into atmosphere. This process continues as water is sprayed by the sprayers 1 1. The amount of sprayed water, droplet size and air velocity in the cold and humid air channels I determine the amount of heat transmitted to the air through the walls of these channels. The amount of heat transmitted to the cold and humid air channels 1 from the hot and humid air channels 2 is small due to the thermal insulation layer 5. Almost all heat comes from the side of the building wall 4. It changes the flow of air which circulates the cold and humid air channels 1 and the hot and humid air channels 2 by changing the position of the flaps 9 and 10. The variation of the air flow varies the cooling temperature. Controlling the productivity of the sprayers 1 1 it controls the amount of evaporated water and consequently the temperature in the cool and humid air channels 1. The process of maintaining the constant temperature inside the building is easy to automate. In the cold season, water spraying is stopped. The flaps 9 and 10 are installed in the fully closed position of cold and humid air channels 1 and hot and humid air ducts 2. Air circulation is switched off. The facade passes in the thermal insulation mode of the building wall 4. The heat losses of the building wall 4 decrease as a consequence of its insulation by the air of the cold and wet air channels 1 , the thermal insulation layer 5 by the air of the hot and humid air channels 2 and outer finish 6.

The roof-mounted device works in the following way.

In the hot weather, when the building needs cooling (fig. 4, 5, 6, 7, 8, 9), the small ridge 33 and the large ridge 34 are opening by rotating the axis 40, and hence, the eccentric 39. It pushes the bar 35 and through it the small ridge 33 lifting it. The bar 35 moves and pushes upward large ridge 34 with the stop 36. Thus, by means of the eccentric 39, the small ridge 33 and the large ridge 34 are raised above the cover 16 and the air penetrates the hot and humid air channels 21 and the open of the cold and wet air ducts 22. Sprayer 32 starts spraying water. Many small droplets form a large surface of contact with the warm air cause intense water evaporation. The air in the area is cooled down and go down from the mouths of the cold and humid air channels 30 through the cold and humid air channels 22 to the preformed channels 29. The air in the channels 21 , heated by the thin cover 16, begins to move upward reducing the heating density. As a result, there is a flow between the open and wet air ducts 22 and the exit of the hot and humid air channels 21 , which continues all time as the air temperature allows the evaporation of the water, the sprayer 32 operates and the small ridge 33 and the large ridge 34 are raised .

In the period when there is no need for cooling, the sprayer 32 stops water spraying, the small ridge 33 and the large ridge 34 are dropped down by means of the eccentric 39. The system goes into thermal insulation mode.

The building cooling device, in the shape of the entire building, works in the following way during warm weather, when the building needs cooling.

Raising of the ridge 49 (fig. 10) and starting of the sprayer 55 results in air draft through the channels 54, the cold and humid air channels 51, the ducts 52, the hot and humid air channels 44 and the hot and humid air channels 42 to the passages 53 in the atmosphere. With the lifting of the ridge 49 and starting sprayer 55, the fan 59 is also switched on, which sends fresh air into the cool and dry air ducts 57. The air in the cold and humid air channels 51 is cooled by spraying water through the sprayers 55 and absorbs the heat from the channels of the cool and dry air 57 through the intermediate wall 50. The air in the cold and dry air channels 57 being propelled by the fan 59 enters the building and provides the living bodies with fresh and cold air. It being used is extracted through the air duct 60.

The other elements work as in the cases described above.

The cooling device of the building, in the shape of the whole building through the discharge works in the following way during warm weather, when the building needs cooling.

Starting fan 61 (fig. 11) and starting sprayer 55 leads to the air movement through the channels 54, cold and humid air channels 51, channels 52, hot and humid air channels 44 and hot and humid air channels 42 to the passages 53 and in atmosphere. With starting sprayer 55, fan 59 is also switched on, which sends fresh air into the cool and dry air channels 57. The air in the cool and humid air channels 51, moving with speed, intensifies water evaporation and thus enhances cooling. Sprayer 55 spray water that absorbs heat from the cool and dry air channels 57 through the intermediate wall 50. The air in the cool and dry air channels 57 is propelled by the fan 59 into the building and provides it with cold and fresh air. It being used is extracted through the air duct 60.

Other elements work similar to the cases described above.

The advantage of cooling facades in the shapes of facade, roof and whole building consists in cooling walls of buildings with the help of the draft effect. The higher the outside temperature, the cooling is stronger. Cooling occurs by day and night. All other technologies are reduced to cooling the air inside building and this process is continuous as long as the heat penetrates from the outside.

The devices considerably reduce the summer indoor air-conditioning costs and winter heating costs, which considerably lowers electricity and heat consumption. The annual energy savings are at least 310kWh/m2 on the south side of the building and reducing of C02 by 0.146 tons/m2. The data presented are for the experimental conditions for the annual heating consumption of 30.1kWh/m2 per year and cooling 14.3kWh/m2 annually at an average annual ambient temperature of 19°C and a humidity of 75%.

Besides, they are simple to achieve, they are not expensive, they do not require the prior surface preparation of the walls. Supply of fresh air is ensured along with the building cooling.
