Description
Technical Field
The utility model 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 a condensation prevention technology is not available on the hardware level, so that once the cooling equipment in the target cabin can not meet the load requirement in the cabin, the situation that condensation is prevented but refrigeration is not carried out can occur, namely the phenomenon that the requirement of condensation prevention is met, so that the environment in the target cabin can not meet the requirement of comfort of personnel is caused.
Disclosure of Invention
The utility model 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 realize the purpose, the technical scheme of the utility model is as follows: the condensation-preventing air distributor for ship consists of air supply box, air diffuser and condensation-preventing nozzle, and the air diffuser is connected to the air supply box, has hole plate connected to the lower part and has condensation-preventing nozzle and baffle around it.
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 sunken structure, and a plurality of anti-condensation nozzles are uniformly distributed on the four peripheral surfaces of the square structure.
Furthermore, the upper surface of the pore plate adopts a structure that the blowing holes are uniformly distributed on a concentric circle.
The utility model 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 utility model not only adopts the design of the anti-condensation nozzle, the design of the pore plate of the diffuser and the design of the jet flow fluid on the equipment level, thereby ensuring the anti-condensation effect of the air distributors, but also considering the influence of the airflow among the air distributors and the influence on the body feeling of people in the cabin, and further ensuring the actual use effect of the device.

fig. 4 shows a schematic view of the diffuser lower orifice plate.
Detailed Description
The utility model 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 the anti-condensation nozzles 4 and the baffle 5.
The air supply box body 1 is made of a heat-insulating and sound-attenuating 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 prevented from generating a cold bridge phenomenon.
The air diffuser 2 adopts a sunken structure, the jet flow speed of the air supply jet flow before entering the cabin is influenced by the baffle plate, so that the influence of the air supply airflow between the adjacent air distributors is greatly reduced. Meanwhile, an opening plate is also arranged below the air diffuser, and on one hand, the opening plate ensures that uncomfortable cold blowing feeling can not be caused to sailors below after jet flow is sprayed out; 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 prior circular strip seam outlet of the diffuser into a square four-side nozzle outlet, so that a plurality of small jets can be formed at the air outlet of the diffuser by low-temperature air conditioning air, 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 ambient air, so that the jets are mixed with 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 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 a restaurant to be more uncomfortable, and simultaneously does not meet the sanitary requirements, but if the air supply temperature is simply increased, the temperature in the restaurant cannot be reduced in a short time, and the comfort feeling of people who have meals in the restaurant can also be influenced.
If the condensation-proof air distributor provided by the utility model 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.
