Abstract

Invention m. used in storage of agricultural products with reduced pressure of the environment. The purpose of the invention is to increase the operational reliability of the device. The second air tube 13 is installed inside the dispenser tube 3. One end 14 of the tube 13 is connected to the tank 1 above the water level 2. The end 15 at the outlet of the dispenser 3 is equipped with an elastic element 16. At the end 15 and limiters 17 are installed above the evaporator 6 . When the pressure of the environment changes, the element 16 changes its volume by opening or blocking the release of moisture from the metering device 3. 1 sludge.

Description

The invention relates to techniques for air conditioning and can be used in systems of hypobaric air conditioning In the storage of agricultural products with low pressure.

The purpose of the invention is to increase operational reliability when working in rooms with reduced air pressure.

The drawing shows a schematic diagram of the proposed device for humidification.

The device for humidification of air contains a container 1 with water 2, a dispenser 3 in the form of a curved tube, one end 4 of which is inserted into the container 1 below the water level, and the other end 5 is located below the container 1 above the evaporator 6 from the capillary-porous material 1, under which is placed pallet 7. The device further comprises an air tube 8, one end 9 of which is connected to the tank 1 above the water level, and the other end 10 is lowered into the pallet 7, the container being sealed, for which a seal 12 is inserted into the neck 11. The device is provided with a second air tube 13 is installed. inside the dispenser tube 3, one end 14 of the second air tube 13 is connected to the container 1 above the water level, and the other end 15 at the outlet of the dispenser 3 is equipped with an elastic element 16, while at the end 15 of the dispenser tube 3 and above the evaporator 16, stoppers 17 are installed the expansion of the elastic element 16.

Device for humidification works as follows.

Water is poured into the container 1 located above the evaporator 6 through the neck 11 with a sealed plug 12 to a level that exceeds the top of the dispenser tube 3. At the same time, as a result of hydrostatic pressure, water fills this tube and begins to flow to the evaporator 6. After closing the sealed plug 12 water outflow continues to full. humidification of the evaporator 6. Excess water accumulates in the pan 7, closes the lower part of the air tube 8 to a certain level, a vacuum forms in the tank 1 and the outflow of water from the dispenser 3 stops. As the liquid evaporates from the surface of the evaporator 6, the amount of water in the pan 7 decreases, the lower part of the tube 8 is connected to the atmosphere and air freely enters the container 1. At the same time, the flow of water from the dispenser 3 resumes. The elastic element 16 does not interfere with the process of water outflow from the dispenser 3. '

When the external pressure decreases as a result of the excess pressure inside the sealed container 1 over the ambient pressure, water flows again from the dispenser 3 to the evaporator 6. With a further decrease in the external pressure, the pressure element inside the container 1 and outside increases its volume, blocking exit from the dispenser 3 and thus preventing the outflow of water, the greater, the greater this pressure difference. The regulation of the flow of water is carried out with the help of expansion limiters 17, which allow changing the degree of overlap by the elastic element 16 of the outlet from the batcher 3. By the position of the limiters, it is possible to completely stop the water flow from the batcher. The movement of the limiters 17 up and down (shown) can be done before operating the storage.

With increasing environmental pressure, the elastic element 16 decreases its volume, slightly opens the outlet of the dispenser 3 and water begins to flow onto the capillary-porous material. When the pressures in the sealed container 1 and the environment equalize, the elastic element 16 ceases to prevent water from flowing out of the dispenser 3 and the device for humidification of air works as before pressure changes.When pressure is equalized in sealed container 1 and in the environment, the elastic element .16 reduces its volume and device for humidification of air works as before pressure changes.

Thus, the proposed device can work in conditions of changing external pressure.
