Technical Field

The invention relates to the technical field of chilled beam air conditioners, in particular to an active chilled beam device and a chilled beam air conditioning system.

Background

The existing active chilled beam basically does not have a perfect condensed water receiving design, and the condensed water phenomenon rarely occurs mainly because the chilled beam is designed for sensible heat exchange, and most designs prevent the condensed water phenomenon from occurring in the aspects of detection and control. The prior art disclosures do not have a corresponding structural design to receive the condensed water, substantially regardless of how the condensed water is collected and may occur.

The active cold beam mainly adopts cold water and hot water as media for heat exchange of the dry type coil pipe, condensation water does not exist during heat supply, and the temperature of chilled water is controlled not to be lower than the dew point temperature of air during refrigeration, so that the condensation water can be avoided. However, the temperature of the fresh air dried at low temperature is usually lower as the injection fluid, so that the surface temperature of the nozzle and the static pressure box is usually lower, and the indoor return air is likely to contact with the injection fluid to cause condensation. The more condensed water on the outer surface of the nozzle is gathered, the more condensed water is easily carried by the high-speed injection fluid to be blown out, and the phenomenon that the air is blown out with water is caused.

Or, because the indoor space gas tightness is not good (for example, the door and window is opened under the high temperature and high humidity weather), the temperature of the chilled water and the condensation prevention control can not rapidly cope with the emergency, and the condensation phenomenon of the dry coil pipe is very easily caused.

In order to avoid the possible dew condensation, it is necessary to design a dew condensation receiving device at the end of the active chilled beam, including a dry coil and a dew condensation collecting device at the outer surface of the low temperature fresh air flow passage.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides an automatic chilled beam device, which solves the problem of active wall-mounted chilled beam condensed water collection, simultaneously realizes full recycling of the condensed water, and prevents the sanitary problem caused by accumulation.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides an active chilled beam device, includes main part, static pressure case, heat exchanger, metal mesh board and nozzle, the static pressure case set up in the inside top position of main part, the nozzle set up in static pressure case below, the heat exchanger set up in the inside below position of main part, the metal mesh board with the heat exchanger cooperation installation, the metal mesh board with be provided with the filter between the heat exchanger, the heat exchanger bottom is provided with water receiving mechanism, the filter presss from both sides has siphon material, the nozzle lower extreme is provided with water collecting mechanism, water collecting mechanism with water receiving mechanism connects. The mesh part on the metal mesh plate corresponds to the installation position of the heat exchanger, the mesh is used for enabling indoor return air to enter the heat exchanger through the surface of the main body for heat exchange, a filter arranged between the metal mesh plate and the heat exchanger is used for filtering dust in the indoor return air, a water receiving mechanism is used for collecting condensed water generated on the surface of the heat exchanger and condensed water generated on the surface of a nozzle, a siphon material is used for guiding the condensed water to the upper part of the filter through siphon action, and evaporation cooling action is generated between the condensed water and the return air, so that the cold energy of the condensed water is fully utilized and the condensed water is effectively recovered; the condensation water accumulation or water flying phenomenon generated by the active cold beam can be avoided.

Furthermore, the side of the main body is provided with a wall hanging plate, and the wall hanging plate and the metal mesh plate are respectively arranged on two sides of the main body. The cold beam is suspended on the wall by a wall hanging plate, and the metal mesh plate is used for the passage of indoor return air, and the two do not interfere with each other.

Further, an air outlet is formed in the bottom of the main body, and an air deflector is arranged at the air outlet. The aviation baffle can adopt manual angle regulation mode, also can be through configuring its automatically regulated of motor control, and the use habit of cooperation difference disposes, promotes user's use and experiences.

Furthermore, a partition plate is arranged between the static pressure box and the heat exchanger, and heat insulation cotton is pasted on the partition plate and the static pressure box. The partition plate is used as a part of the static pressure box to separate the static pressure box from an air duct below, and air in the static pressure box can only enter from an air pipe connector and be sprayed out from a nozzle; the insulation cotton on the partition plate and the static pressure box can prevent the condensation phenomenon on the outer surface of the static pressure box.

Furthermore, an air pipe connector is arranged on the main body and is fixed on the main body through screws. The air pipe of other equipment is connected through the air pipe connector, and the disassembly and the assembly of the air pipe are convenient by utilizing the screw fixation.

Furthermore, a water outlet is arranged at the bottom of the main body and is arranged in the middle upper area of the side wall of the water receiving mechanism. The position of the water outlet is a certain distance higher than the bottom of the water receiving mechanism, so that the overflow drainage effect can be ensured, and condensed water is prevented from being gathered at the bottom of the water receiving mechanism.

Furthermore, the water collecting mechanism is a water collecting tank, the water receiving mechanism is a water receiving tray, and a flow guide pipe is connected between the water collecting tank and the water receiving tray. The water collecting tank is used for collecting condensed water generated on the outer surface of the nozzle and flows to the water receiving tray through the flow guide pipe for repeated use.

Furthermore, the water collecting mechanism is made of soaked cotton, the soaked cotton is adhered to the outer surface of the nozzle, and a guide pipe is connected between the soaked cotton and the water receiving tray. Through soaking cotton parcel at the nozzle surface, guaranteed that the collection of nozzle surface condensation water is abundant, through the used repeatedly on the water collector of diversion pipe flow after the condensation water is collected.
