Description

Technical Field

[0001] The utility model relates to the technical field of central air-conditioning systems, in particular to a curtain box cold beam. Background Art

[0002] The chilled beam is a combination of the primary air system and the air-water heat exchange system. It uses proprietary nozzle technology to induce the room air to enter the chilled beam and exchange heat with the heat exchange coil. The air after heat exchange is mixed with the primary air and evenly delivered into the room through slit-type air vents or grille air vents. However, most chilled beam equipment does not have a water accumulation tray and requires dew point detector control. Once out of control, condensation water will be generated, causing damage to the ceiling. Therefore, the water supply temperature must not be too low to control the generation of condensation water, resulting in a small cooling capacity. Utility Model Content

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with traditional chilled beam equipment, which does not have a water accumulation pan and requires a dew point detector for control, condensation will be generated once it gets out of control, causing damage to the ceiling. Therefore, the water supply temperature must not be too low to control the generation of condensation, resulting in a small cooling capacity. This device collects and discharges condensation by setting up a water accumulation pan structure. There is no need to worry about condensation damaging the ceiling, so that lower temperature water supply can be used for cooling to achieve a stronger cooling effect. At the same time, the air outlet is changed to downward air outlet, so that the chilled beam can be set above the windowsill, isolating the outdoor heat from penetrating into the room through the window. At the same time, the installation position is far away from where people move and rest, so there is no sense of wind blowing on people, which greatly improves people's comfort.

[0014] 2. When condensed water is generated, the air contacts the heat exchange coil, and the water vapor in the air is cooled and liquefied and attached to the fins. The fins are made of hydrophilic materials to ensure that the condensed water flows along the fins into the water collection tray and does not drip from the air supply port. After entering the water collection tray, the condensed water flows through the drain pipe to the external pipe to complete the automatic treatment and discharge of the condensed water, so as to solve the problem that most chilled beam equipment has a weak ability to handle condensed water, which reduces the user's comfort experience;

[0015] 3. During cooling, the fixing seat is located inside the shell, and the heat exchange coil and fins are fixed by the fixing block. The water exchange pipe is connected to the external pipe through the connecting pipe, and the water is passed from the water exchange pipe into the heat exchange coil and then discharged from another set of water exchange pipes to form a water circulation in the heat exchange coil. The air inlet pipe is connected to the external pipe through the connecting flange, and the treated primary air is sent to the static pressure box with a constant air volume and relatively low static pressure conditions, and then ejected through the high-speed jet of the nozzle in the mounting seat in the cold beam. According to the Venturi effect, the high-speed airflow through the nozzle generates a negative pressure area in the mixing area, thereby inducing the indoor air to return from the side perforated flower plate, pass through the heat exchange coil and mix with the primary air after heat exchange, and then be sent into the room through the air supply port at the bottom of the shell to reduce the temperature in the room.
