Description
Technical Field
The invention relates to the field of marine equipment, in particular to a marine air conditioner tail end device, and particularly relates to a spiral runner variable air volume marine air distributor.
Background
The existing marine air conditioner usually adopts a centralized fresh air system, the air supply speed is high, and in order to avoid overlarge vibration noise of an indoor fan, the tail end of the existing marine air conditioner generally adopts a fan-driven air distributor. With the continuous rising of the price of crude oil and the improvement of the requirement of people on the comfort level of the cabin environment, the relevant specifications of the international maritime organization have higher requirements on energy consumption and noise control, and the energy-saving, environment-friendly, low-noise and modular design of the marine air conditioning equipment inevitably becomes the trend of the technical development of the marine air conditioner.
Marine air distributor among the prior art ubiquitous two problems when the design: firstly, the inside air current direction of air distributor changes frequently, has increased the resistance loss. For example, a terminal variable air volume electric heating air distributor with patent number 201610678411.5, the inside of which is provided with an L-shaped flow channel, has the functions of electric heating and the like, but an air inlet adjusting device at an air supply inlet is a circular pipe with holes, and the air flow is blown out from the small holes and impacts on the inner wall surface of the air distributor to easily cause the vibration noise of a box body; for example, a muffling air distributor with patent number 201520293049.0 has a plurality of zigzag "muffling labyrinth" in which an air flow is made to flow in a U-shaped manner inside a box body, so that noise indexes are greatly reduced, but resistance loss is large after multiple times of flow in a rotating manner, and an energy-saving effect is not good, because in fluid mechanics, the rotating flow is fluid backflow, a process is complicated, when the air meets an obstacle, the speed suddenly drops to zero, dynamic pressure is converted into static pressure, then the static pressure becomes larger and larger, the air flow is driven to flow, that is, the static pressure is converted into dynamic pressure, and unrecoverable frictional heat energy is generated in the process, so that energy loss is large; a low noise cloth wind ware that corresponds with it, patent number is 201620635282.7, adopts a plurality of honeycomb ducts to wind-guiding, directly sends out the air current by the play tuber pipe, and the air current can not form the swirl in the honeycomb duct, has reduced pneumatic noise, but the honeycomb duct pipe diameter is little, only has 0.5cm, consequently, this kind of cloth wind ware still does not solve the problem that resistance loss is big, energy loss is big. When the air distributor is optimally designed, the shape and the structure of the silencing partition plate are mainly changed to control airflow pulsation vortex so as to reduce the generation of pneumatic noise. However, the partition plate and the flow guide pipe can greatly increase the pressure loss of the air distributor, and the airflow direction is changed for many times due to the unreasonable shape and structure of the partition plate, such as the rotary turning of the cross section of the flow passage, and the airflow vortex cannot be eliminated fundamentally. Therefore, the energy consumption of the air conditioner is increased, the comfort inside the cabin is not obviously improved, and the noise reduction effect is not good.
The other problem is that the air inlet adjusting device is not properly designed, and the air quantity adjusting precision is low. For example, the wall of the air inlet pipe of the novel marine air distributor with the patent number of 201110389421.4 is provided with a plurality of air inlet holes, the wall of the air inlet pipe is sleeved with an adjusting pipe with a primary adjusting mechanism, the adjusting holes of the adjusting pipe and the air inlet holes of the air inlet pipe can be in a closed state or a partially or completely communicated state, and the like, the air inlet device is complicated and tedious, and the air volume adjusting and controlling precision is not high; as another example, the isolated muffling air distributor disclosed in patent No. 200510227007.1 and the low-noise air distributor disclosed in patent No. 201120487896.2 both control the air volume by moving the valve plate back and forth to gradually approach or completely contact the air inlet pipe of the air distributor.
