Description
Technical Field
The invention relates to a condensation-preventing air distributor for ships, which is mainly suitable for high-temperature and high-humidity ship cabin areas such as restaurants and the like and is used for preventing condensation when low-temperature air treated by an air conditioning device is fed into the areas.
Background
In order to prevent the condensation of the air supply, in the prior air conditioner control system for processing the air in the area, the air supply temperature is controlled in stages according to the dew point temperature in the cabin, and when the dew point temperature in the target cabin is overhigh, the air supply temperature is ensured to be above the dew point temperature, thereby preventing the condensation of the air supply spray.
The solution only temporarily solves the problem of air supply condensation of the high-temperature and high-humidity cabin of the ship on the control strategy level, and the hardware level has no technology for preventing condensation, so that once the cooling equipment in the target cabin can not meet the load requirement in the cabin, the situation of preventing condensation but not refrigerating can occur, namely the phenomenon that the requirement for preventing condensation is met, so that the environment in the target cabin can not meet the requirement for comfort of personnel is achieved.
Disclosure of Invention
The invention aims to provide a condensation-preventing air distributor for ships, which can effectively prevent air supply condensation on a hardware level, is convenient to disassemble, assemble and maintain on site and can be deployed in high-temperature and high-humidity areas such as ships and restaurants.
In order to achieve the purpose, the technical scheme of the invention is as follows: a condensation-preventing air distributor for ships comprises an air supply box body, an air diffuser and a condensation-preventing nozzle, wherein the air diffuser is connected with the air supply box body, the lower part of the air diffuser is connected with a pore plate, and the periphery of the air diffuser is provided with the condensation-preventing nozzle and a baffle.
Furthermore, the air supply box body is internally made of a heat-preservation and noise-reduction material of radiation centrifugal glass wool.
Furthermore, the air diffuser adopts a concave structure, and a plurality of anti-condensation nozzles are uniformly distributed on the square peripheral surface.
Furthermore, the upper surface of the pore plate adopts a structure that the blowing holes are uniformly distributed on a concentric circle.
The invention has the beneficial effects that:
at present, the problem of air supply condensation of a high-temperature and high-humidity cabin of a ship is temporarily solved only on the level of a control strategy, and no technology for preventing condensation is provided on the level of hardware. The invention adopts the design of the anti-condensation nozzle, the design of the diffuser orifice plate and the design of the jet flow fluid on the equipment level, ensures the anti-condensation effect of the air distributors, simultaneously considers the air flow influence among the air distributors and the somatosensory influence on personnel in the cabin, and further ensures the actual use effect of the device.

fig. 4 shows a schematic view of the diffuser lower orifice plate.
Detailed Description
The invention is further described with reference to the following figures and examples.
As shown in fig. 1 to 4, the condensation prevention air distributor for ships of the present invention is composed of an air supply box 1, a diffuser 2, a condensation prevention nozzle 4, and the like.
The air diffuser 2 adopts a sunken structure, the upper surface of the air diffuser is connected with the air supply box body 1, the lower surface of the air diffuser is connected with the square hole plate 3, and the periphery of the air diffuser is provided with an anti-condensation nozzle 4 and a baffle 5.
The air supply box body 1 is internally made of heat-insulating and sound-damping material made of radiation centrifugal glass wool, so that the air supply noise of the air distributor is reduced while the surface of the condensation-preventing air distributor box body is ensured not to generate a cold bridge phenomenon.
The air diffuser 2 adopts a sunken structure, the jet wind speed of the air supply jet before entering the cabin is influenced by the baffle plate, and the influence of the air supply airflow between the adjacent air distributors is reduced to a great extent. Meanwhile, a perforated plate is also arranged below the air diffuser, and the perforated plate ensures that uncomfortable cold blowing feeling can not be caused to lower crews after jet flow is ejected; on the other hand, a buffer area is formed on the lower surface of the air diffuser, and a small part of mixed air can enter the buffer area through the pore plate under the action of entrainment, so that condensation on the lower surface of the air diffuser is avoided.
In addition, the device changes the circular slit outlet of the existing air diffuser into a square four-side nozzle outlet, so that low-temperature air conditioning air can form a plurality of small jets at the air outlet of the air diffuser, negative pressure is formed around the nozzle by utilizing the higher flow speed and the motion characteristic of the jets, and the induction and entrainment effects are formed on the ambient air, so that the jets are mixed with the indoor air in a short distance away from the air outlet, the air supply temperature is further improved, and the air outlet, the surface of the air diffuser and the wall surface of the cabin are ensured not to be condensed.
In order to meet the cooling load requirement of a high-temperature and high-humidity area on a ship, low-temperature air supply processed by an air conditioning device needs to be sent into the area through an air distributor, and if the dry bulb temperature of the area is 30 ℃, the relative humidity is 70% and the dew point temperature is 24 ℃, the air supply at the temperature of 13 ℃ is sent through a common air distributor, airflow condensation is generated, namely the phenomenon of air supply 'spraying' is generated. Condensation can cause the hot and humid environment in such areas as dining room to be more uncomfortable, also can not satisfy the sanitary requirement simultaneously, but if rely on the mode that improves air supply temperature alone, then the temperature in the dining room also can not reduce in the short time, also can influence the personnel's comfort degree impression of having dinner in the dining room.
If the condensation-proof air distributor provided by the invention is arranged on the ceiling 6 in a restaurant, the air in the cabin and the low-temperature air supply are fully mixed under the action of induction and entrainment, the temperature of the air sent into the cabin is improved in a phase-changing manner on the premise of ensuring that the cold load in the cabin can be met, and the problem that the condensation and the heat load can not be met at the same time is solved.
