1. Size of wet delivery port, outlet wind speed and wind temperature determination

According to relevant regulations in design specifications for heating, ventilation and air conditioning (GB50736-2012) of civil buildings and special climatic conditions of plateau areas, the following indoor environment parameter control ranges are selected:

indoor air temperature: 18-24 deg.C

Indoor air relative humidity: 30 to 50 percent

Indoor air flow rate: less than or equal to 0.20m/s

According to ANSYS software simulation of environmental parameters of all points of a plane where a human body breathing area is located as shown in figure 11, the diameter of a moisture sending port and the outlet air speed are determined, and the moisture sending port and the outlet air speed are ensured to meet the requirements of the control range.

Numerical simulation is carried out by taking an airport boarding corridor bridge as an example as follows:

according to the relevant regulations in passenger boarding bridge (MH/T6028-2016), the width of the interior of the boarding bridge passage should be no less than 1400mm and the clear height should be no less than 2100 mm. As shown in fig. 11, a vertical interface with a height of 0.20 to 2.00m and a width of 1.30m was selected for a boarding bridge with an internal width of 1500mm and a clear height of 2300mm, and the simulation was performed, i.e., a shaded portion.

The flow field assumption of the plane where the ANSYS software simulates the human breathing zone is as follows:

the diameter of the wet delivery openings is 25mm, the wet delivery openings are arranged in a 4 multiplied by 5 array mode, the interval between every two adjacent wet delivery openings is 0.30m, and the height between the lowest wet delivery opening and the ground is 0.50 m.

When the wind speed at the outlet of the moisture sending port is 0.75m/s, the speed cloud chart is shown in figure 12;

by analyzing comfort and economy, the air speed at the outlet of the moisture sending port is determined to be 0.75m/s, and the air supply quantity of each moisture sending port is 5.30m at the moment3H, total air supply of 21.20m3/h。

Setting the air temperature at the outlet of the moisture sending port to be 25 ℃, wherein the air temperature distribution on the plane shown in the figure 11 when the air speed is 0.75m/s is shown in figure 13, and the temperature of the air temperature distribution is basically about 22.5 ℃ and meets the requirement;

the relative humidity of the air at the outlet of the moisture sending port is set to be 50%, and the relative humidity of the air on the plane shown in fig. 11 is about 32% when the air supply temperature is 25 ℃ and the air speed is 0.75m/s in fig. 14, so that the requirement is met.

Thus, the dimensions of the components of the device are, according to the requirements of the relevant specifications: the diameter of the wet delivery openings is 25mm, the wet delivery openings are arranged in a 4 multiplied by 5 array type, the interval between every two adjacent wet delivery openings is 0.30m, and the height between the lowest wet delivery opening and the ground is 0.50 m; the outlet air speed of the moisture sending port is 0.75m/s, the outlet air temperature is 25 ℃, and the relative humidity of the air at the outlet is 50%.

2. Determination of humidification amount and heating amount of auxiliary heater

Take Lhasa city (atmospheric pressure 65.8kPa) as an example:

the air temperature at the outlet of the wet delivery port is 25 ℃, and the total air delivery is 21.20m3/h;

The indoor air state is: the temperature of the dry bulb is 18 ℃, the relative humidity is 12 percent, and the moisture content is 2.35g/kg of dry air;

the air humidifying state is as follows: the temperature of the dry bulb is 25 ℃, the relative humidity is 50 percent, and the moisture content is 15.35g/kg of dry air;

the humidification quantity is as follows:

1.904kg of water is added per day, calculated as 8 hours of heating per day.

Water state before entering the water storage tank: the temperature is 15 ℃, and the density is 999.06kg/m3

Softened water state after heating: the temperature is 25 ℃, the density is 996.99kg/m3

The heating quantity per hour of the auxiliary heater is as follows: q1.007 × 0.238 × (25-15) 2.39kJ

3. Sensor set value

According to the requirements of relevant specifications, the humidity sensor is set to be 25-35%, and the temperature sensor is set to be 20-24 ℃.

In the device, a large amount of air enters the device from the air inlet, passes through the wet fiber roller shutter carrying a large amount of wet components and is changed into wet air, and the wet air is delivered to a breathing area of a person in a moving space in a wet jet flow mode under the induction action of airflow at the outlet of the siphon branch pipe of the air supply device. The relative humidity of the treated air can reach 29.7-34.6%, and the temperature can reach 21.5-23.5 ℃. In addition, the tap water needs to be softened by a 4A molecular sieve to eliminate calcium and magnesium ions in the water and prevent white pollution. When the indoor temperature is low, the auxiliary heater can be started to preheat softened water in the water storage tank; the heat released by the phase change material layer can be absorbed at night, the power of the auxiliary heater is reduced, and the purpose of energy conservation is achieved.

In conclusion, the invention can realize the high-efficiency and energy-saving local humidification of moving spaces such as corridor bridges, sentry boxes, temporary workstations and the like by reasonably controlling the operation parameters of the fan and the opening degree of the fan, gradually changing the concentration of wet components from high to low in the range from the height of a person breathing area to the ground and using the bottom roller of the device in cooperation, and is suitable for extremely dry plateau areas.
