SK8900Y1 - Acoustic ceiling diffuser with stabilized air supply - Google Patents

Abstract

The acoustic ceiling diffuser using the heat pipe principle with the introduction of a stabilized air supply is a separate, closed mounting element. The evaporating part forms a visible part and is formed by a hollow welded steel block (1) with the transverse openings (3) and the ribs (7), which is located in an air duct (8), where the fans (9) are located, to remove or supply heat to the room heating or cooling. A vapour collector (2) and a transfer pipeline (4) forming an adiabatic part of the heat pipe are firmly connected to the hollow welded steel block (1). A heat exchanger (5) is firmly connected to the transfer pipeline (4), which transfers heat or cold and which is connected to the energy source of the building by an inlet pipeline (11) and an outlet pipeline (12). The air from the room is sucked by means of the fans (9) and is guided by means of a rectifier (6) on the ribs (7) and through the transverse openings (3) of the hollow welded steel block (1), where the air is either cooled or heated.

Description

Technical field

Acoustic ceiling diffuser with stabilized air supply falls into the area of technical security of buildings, specifically into the area of heating, cooling and air-conditioning systems.

Prior art

The role of ceiling diffusers and panels is to ensure an adequate temperature by cooling, and thus ensure thermal comfort for as many people as possible in the area, even during hot summer sunny days. The main benefit is the even cooling of the space in which the system is located. A great advantage is also the temperature of the refrigerant, which is higher than air conditioners, and thus there are no such large temperature losses. With regard to human thermal comfort, the system of cooling panels is much more suitable compared to conventional methods of air conditioning, there is direct heat exchange between human body and refrigerated space The performance of cooling panels can be affected by their arrangement, construction, or possible addition of a forced convection component using an additional fan, and thus obtaining a possible exchange of air in the room.

Existing devices fall into several categories based on different heat transfer by convection or radiation. The dry method of cooling is realized by fitting system boards, which are installed instead of classic plasterboards of new boards. In these system boards, the recessed tubes are ready for connection to the cooling circuit, the spacing of which is chosen so as to achieve the highest possible cooling performance and also to maintain the strength of the plasterboard of the new board, which is additionally reinforced with pulp fiber. Another possible use is an acoustic cooling ceiling, where the base of the cooling panel is formed by two glued perforated plasterboard panels, the openings of which are arranged one above the other. Due to this perforation, these panels have a sound-absorbing effect. The wet method of cooling is realized by fixing the pipes to the ceiling using fixing strips and subsequent covering with plaster with a thickness of about 2 cm.

U.S. Pat. No. 3159090 describes an acoustic cooling panel for ceiling cooling and heating systems. The panel is mounted at a defined distance from the ceiling, thus creating space for the flow of cold or hot air. The panel has openings in the direction of the room through which cold or hot air flows.

U.S. Pat. No. 5,259,157 describes an acoustically insulated ceiling panel for buildings. The panel consists of several parts, which are connected by insulating material. The lower parts of the panel, which are oriented to the space of living rooms, are perforated with circular openings, which contribute to the absorption of sound from the room.

European patent EP 2 045 536 A2 discloses a ceiling cooling panel for space heating and cooling, which consists of a perforated plate with grooves for accommodating capillary tubes. Cooling or heating medium, most often water, flows in the pipes. The tubes are partially or completely embedded in the panel from the top.

Another principle of ceiling panels was presented in the publication .. Excrement investigation of cooling performance of a novel HVACsystem combining natural ventilation with diffusion ceiling inlet and TABS ", by Tao Yu, Per Heiselberg, Bo Lei, Michal Pomianowski, Chen Zhang, Rasmus Jensen, who designed a cooling panel with a diffuse part oriented to the refrigerated space. In the upper part of the panel, pipes with cooling water are placed in the concrete, the air gap creates a space for the flow of air from the surroundings and the diffuse part then serves to transfer cold air into the space. The acoustic cooling panel is made of wood shavings in combination with a cement mixture, so it acts as a thermal insulator, and thus can affect the heat transfer between the cooling ceiling and the refrigerated room. The diffuse ceiling panel is made of wood shavings in combination with a cement mixture. However, the use of circulating air increases the convective heat transfer, and thus increases the cooling capacity of the ceiling by approximately 5-35%. The heat transfer between the cooling ceiling and the cooling space consists of convection convection.

The essence of the technical solution

These disadvantages are eliminated by the use of an acoustic ceiling diffuser using the heat pipe principle, where the heat pipe ensures a stable heat transfer and an even distribution of the supplied air.

The acoustic ceiling diffuser with a stabilized air supply uses a combination of natural or forced convection and radiation to create favorable temperature conditions. The use of a heat pipe enables local adjustment of the temperature of the supplied air, as well as ensuring the required hygienic exchange of air in the ventilated space and the use of the structure as a distribution element. The exhaust part of the heat pipe with transverse openings normalizes the air flow exiting into the cooled or heated space, thus preventing the swirling of dust in the room.

When adjusting the air quality, two cases are possible, cooling or heating the supply air. In the case of cooling, the air supplied by the perforation is cooled by the exhaust part of the heat pipe. In the case of air heating, the exhaust part is replaced by a condensing part, the circulation of the heat pipe is rotated, the supplied air is heated by passing through the perforation of the proposed structure.

The acoustic ceiling diffuser with a stabilized air supply is a separate, closed mounting element. The dimensions of this element can be adapted to the design, construction, performance requirements of the ventilated space. The diffuser consists of two exchangers, which form the main parts of the heat pipe, ensuring the flow of the working medium between these exchangers, pipes supplying cooling / heating water depending on the quality requirement of the supplied air and fans allowing air circulation. The exchanger representing the lower wall of the diffuser is perforated. This perforation allows the distribution of air, and thus the adjustment of the temperature of the air supplied to the ventilated space. Cooling / heating water flows through the heat exchanger at the top, depending on the supply air temperature requirement. The exchanger in the upper part is separated from the supply air by a wall.

The diffuser can work in two modes. In the circulation mode, when the air is discharged directly from the ventilated space, treated by a vent. Air circulation is ensured by fans mounted directly in the diffuser structure. The temperature of the supply air, and thus the cooling / heating power of the diffuser, can be changed by the temperature of the cooling / heating water as well as by the power of the fans ensuring air circulation. Another mode is the use of the diffuser as a supply distribution element, where the air flowing through the perforation is supplied by a fan or air handling unit from the exterior and its quality is directly affected by the diffuser.

The acoustic ceiling diffuser with a stabilized air supply is mounted on the ceiling by means of steel hinges. The combination of the cooling / heating water flow, the working medium flow in the heat pipe exchangers results in cooling, resp. ventilated space heating.

Examples of embodiments

The acoustic ceiling diffuser with a stabilized air supply is a separate, closed mounting element. It works on the principle of a heat pipe with a closed loop and consists of a heating part, a condensing part and a transfer pipe. The exhaust part forms a visible part and is formed by a hollow welded steel block 1 with transverse openings 3 and ribs 7, which is located in the air duct 8, where fans 9 are located for removing or supplying heat for heating or cooling the room. The transverse openings 3 of the hollow welded steel block 1 are formed by steel tubes extending vertically across the entire hollow welded steel block 1 and are firmly welded to the hollow welded steel block 1. A vapor collector 2 and a transfer line 4 forming an adiabatic part of a heat pipe are firmly connected to the hollow welded steel block 1, and a heat exchanger 5 which transfers heat or cold is firmly connected to this line. The heat exchanger 5 is connected to the energy source of the building by an inlet pipe 11 and an outlet pipe 12. The air from the room is sucked in by means of fans 9 and is guided by means of a rectifier 6 on the ribs 7 and through a hollow welded steel block 1, where the air is either cooled or heated, thus treated is supplied back to the room.

Industrial applicability

Acoustic ceiling diffuser with stabilized air supply can be used for energy supply and distribution for the needs of cooling residential office spaces in buildings.
