Description
Technical Field
[0001] The utility model belongs to the technical field of chilled beam equipment, in particular to a bottom-outlet chilled beam. Background Art
[0002] Existing residential central air conditioning systems primarily fall into two categories: variable refrigerant flow multi-split systems (VRFs) and air-source heat pump systems. Both systems utilize fan coil units with fan motors at the end. These systems suffer from strong drafts, high noise levels, a lack of fresh air, and complex and expensive maintenance.
[0003] Traditional chilled beams do not have water accumulation trays and require dew point detectors for control. Once out of control, condensation will occur, causing damage to the ceiling. In addition, due to the high water supply temperature and small cooling capacity, a large number of terminal configurations are required, resulting in high costs. Utility Model Content
[0004] In order to solve the comfort problem existing in traditional household central air-conditioning, make the air-conditioning system healthier, more comfortable and humane, and at the same time reduce the initial investment as much as possible, the utility model provides a bottom-outlet cooling beam.
[0005] In order to achieve the above functions, the technical solution adopted by the present invention is as follows: a bottom-outlet cooling beam, including a casing, a heat exchange coil is installed inside the casing, and the heat exchange coil is arranged in two rows in a V-shape, a jet nozzle is provided at the center position inside the casing, a water accumulation tray is provided at the bottom of the casing, a drainage hole is provided on the water accumulation tray, return air outlets are provided on the front and rear sides of the casing, a return air perforated plate is installed at the return air outlet, an air outlet is provided at the bottom of the machine, and the air outlet is located below the heat exchange coil.
[0006] As a preferred technical solution of the present invention, the heat exchange coil forms an angle of 60° with the bottom plate of the casing, and the fins of the heat exchange coil are hydrophilic fins.
[0007] As a preferred technical solution of the present invention, a primary air inlet is provided on the front side of the casing, and a condensate drain outlet, a cold water supply pipe interface and a cold water return pipe interface are provided on the rear side of the casing.
[0008] As a preferred technical solution of the present invention, the condensed water drain outlet is connected to the drain hole on the water accumulation tray.
[0009] As a preferred technical solution of the present invention, a static pressure box is provided at the top of the inner front side of the casing.
[0010] As a preferred technical solution of the present invention, the top of the outer side wall of the casing is evenly provided with lifting ears, and the side surrounding wall of the casing is provided with a thermal insulation interlayer.
[0011] Compared with the prior art, the utility model adopts the above structure to achieve the following beneficial effects: the cooling beam designed by the utility model has no fan motor, the noise is extremely low, the air supply is soft, and the indoor temperature distribution is more uniform; the heat exchange coil and the bottom plate are at an angle of 60 degrees, and the fins are hydrophilic fins, which ensure that the condensed water flows along the fins into the water collection tray and will not drip from the air supply port; there are two rows of heat exchange coils inside the cooling beam, which are arranged in a V shape, and the nozzle sprays air in the middle, so that the wind on both sides can be induced to exchange heat through the two groups of heat exchange coils to the maximum extent, which greatly increases the cooling efficiency. The cooling capacity of the beam, the supply and return water temperature of the chilled beam in summer is 7℃ / 12℃, which can greatly improve the cooling capacity of the chilled beam. At the same time, due to the water accumulation tray, there is no need to worry about the generation of condensed water, and the condensed water is discharged through the drainage holes of the water accumulation tray; due to the low water supply temperature and the large cooling capacity of the chilled beam, the number of chilled beams is greatly reduced compared with traditional chilled beams. At the same time, since there is no need to consider the condensed water problem, no dew point detector is required, which makes the system control simpler, reduces the later maintenance, eliminates the hidden dangers of condensed water, greatly reduces the initial investment, and can be more widely promoted and applied.

Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The present invention will be further described below in conjunction with the accompanying drawings.
[0019] like Figure 1-4 As shown, the utility model provides a bottom-outlet cooling beam, including a casing 1, a heat exchange coil 2 is installed inside the casing 1, and the heat exchange coil 2 is arranged in two rows in a V shape, the heat exchange coil 2 and the bottom plate of the casing 1 form an angle of 60 degrees, and the fins of the heat exchange coil 2 are hydrophilic fins. A jet nozzle 3 is provided at the center position inside the casing 1, and the jet nozzle 3 can spray air in the center, so as to induce the wind on both sides to pass through the two groups of heat exchange coils 2 for heat exchange to the maximum extent, thereby greatly increasing the cooling capacity of the cooling beam. 1 is provided with a water collection tray 4 at the bottom, and a drainage hole is provided on the water collection tray 4. The water collection tray 4 collects and discharges the condensed water uniformly. The front and rear sides of the casing 1 are provided with return air vents 5. The return air vents 5 are installed with return air perforated panels 6, which can protect the internal heat exchange coil 2 and increase the aesthetics. The bottom of the machine is provided with an air outlet 7, which is located below the heat exchange coil 2. When cooling, cold water is introduced into the heat exchange coil 2, and the temperature is low. The hot air will automatically sink after cooling through the heat exchange coil 2 and be sent out through the air outlet 7.
[0020] like Figure 1-4 As shown, a primary air inlet 8 is provided on the front side of the casing 1, a condensate drain outlet 9, a cold water supply pipe interface 10 and a cold water return pipe interface 11 are provided on the rear side of the casing 1, the condensate drain outlet 9 is connected to the drainage hole on the water accumulation tray 4, a static pressure box 12 is provided at the top of the internal front side of the casing 1, and hanging ears 13 are evenly provided on the top of the outer wall of the casing 1, and an insulation interlayer 14 is provided in the side wall of the casing 1.
[0021] When in use, the treated primary air is sent to the primary air inlet 8 of the chilled beam under constant static pressure conditions, and then ejected through the jet nozzle 3 in the chilled beam with high speed jets. According to the Venturi effect, the high-speed airflow through the jet nozzle 3 generates a negative pressure area in the mixing area, thereby inducing the indoor air to pass through the return air perforated panels 6 on both sides and pass through the heat exchange coil 2 for heat exchange and mix with the primary air, and then be sent into the room through the air outlet 7. Since the air outlet 7 is below the heat exchange coil 2, when cooling, the heat exchange coil 2 passes through the air outlet 7. When cold water enters, the temperature is relatively low, and the hot air will automatically sink after cooling through the heat exchange coil 2 and be sent out through the air outlet 7. The heat exchange coil 2 and the bottom plate of the casing 1 form an angle of 60°, ensuring that the condensed water flows along the fins into the water collection tray 4 and will not drip from the air supply port, but be discharged from the condensed water drain port 9. The two rows of heat exchange coils 2 arranged in a V shape and the jet nozzle 3 spray air flow in the center can maximize the induction of wind on both sides to pass through the two groups of heat exchange coils 2 for heat exchange, greatly increasing the cooling capacity of the chilled beam.
[0022] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
