Compared with the glass multi-span greenhouse, the cost of the glass multi-span greenhouse is lower, and the quality of the sunplate is lighter. The safety is higher; the thermal insulation effect of the sun board is better; the all-steel skeleton structure is sturdy and durable, and the service life is long, but the light transmission efficiency of the sun board decreases with the use time; the sun board needs to be replaced after serious aging; thermal insulation facilities are also needed in winter. Intelligent greenhouse is a kind of modern planting which integrates data acquisition, central calculation and automatic control of equipment. High-tech intelligent greenhouse is generally equipped with high automation facilities such as external sunshade system, internal masking system, internal heat preservation system, forced ventilation and cooling system of wet curtain fan, top ventilation system, heating system, power distribution / control system and so on. The managers input the data and control parameters needed for planting crops into the computer, and the intelligent greenhouse can realize unmanned automatic operation.

Actually, it can. It has long been a car sunshade, which is designed according to the shape of the car and covers the area from the front windshield to the rear windshield, which can effectively reduce the temperature inside the car at high temperatures.

The beneficial effect of the utility model is that the sunshade picnic insulation bag of the utility model not only has excellent high temperature heat preservation and low temperature heat preservation effect, but also has a skeleton inside the package body, which can be used as a stool, and is built with detachable sunshade umbrellas, which is more suitable for carrying out, more powerful in function and more practical.

7. Baby Blanket: Having a lightweight, soft baby blanket in your diaper bag is incredibly useful. It can keep your little one warm, serve as a clean surface for playtime, or even act as a makeshift sunshade. Look for a blanket made from breathable materials suitable for different climates.

Employers can also perform a series of tasks remotely throughout the building. These tasks range from locks that automatically protect employees and construction workers, to operating sunshades to introduce sunlight during the day and close them at sunset, to occupancy monitoring, and receive real-time reports from employees on building problems in need of repair, and more. Employers can solve maintenance and a range of problems without placing employees. By accessing all data from one dashboard, they can comprehensively manage occupancy and space utilization in real time, and plan space optimization and leasing.

Of course, if you buy some of the more expensive models, then the meters in your car are likely to come from high-end watch manufacturers, such as Jaeger and Wanguo. For example, the Mercedes-Benz 680s dashboard in 1928 is dotted with more than a dozen circular pointer dashboards, which can be mistaken for the built-in display cabinets of a watch shop. Moreover, even if it comes from a famous family, it can not solve the problem that the instrument is not easy to read due to the reflection on the surface of the instrument and the lack of radians on the instrument as a whole, which gives birth to the emergence of sunken instruments and instrument sunshades.

At the scene, there was an endless stream of citizens coming to buy tents, and the shop assistants were also busy introducing goods to customers. According to the shop assistant, “Outdoor tents include sunshade picnic tents and overnight tents for wind and rain protection, and the former sells relatively well.” With a fast-opening picnic tent of more than 300 yuan and a picnic mat of dozens of yuan, you can have a perfect picnic and enjoy a wonderful weekend. ”

11. After the concrete has been poured, covering or spray curing should be carried out immediately before the initial setting. Concrete thermal insulation materials can be made of plastic film, geotextiles, gunny bags, flame retardant quilts and so on. If necessary, wind shielding shed or sunshade greenhouse can be set up. In the thermal insulation maintenance, the temperature difference and cooling rate of the concrete pouring body should be monitored on the spot, and when the measured results do not meet the requirements of the temperature control index, the thermal insulation maintenance measures should be adjusted in time.

When it is also hot, the way to build a sunshade or sunshade net over the whale can be effective in direct sunlight. To achieve the purpose of cooling, apply reflective radiation paint three times. For the original state of Whale Island Paradise, Shanghai Enyu Media does not recommend applying reflective paint directly to the shell of Whale Island. It can be used on the sunshade, and then perpendicular to the light. Play the role of outward refraction. To achieve the purpose of cooling, recruit four convection ventilation. Enyu Media Whale Island maintains the original intention of the design. A three-door design is used to design a pedestrian door on the head of the whale. Emergency doors are designed on both sides, which not only deal with emergencies, but also play the role of ventilation and air convection. Reduce the indoor temperature, recruit five surrounding green plants, one of the functions of green plants is to filter and precipitate impurities in the air, absorb carbon dioxide and exhale oxygen.

It can reduce the harm of cold current. When the temperature in the shed is below ℃ for a long time, the mulch such as straw bag non-woven sunshade net should be covered in the greenhouse at night to prevent frost damage and take basin fire or furnace fire to heat temporarily. Open fire can not be used when heating, in order to prevent smoke damage, it is necessary to set up a flue to put harmful gases outside, focusing on the heat preservation and anti-freezing of vegetables and seedlings in the greenhouse. For eggplant seedlings which are in the early stage of raising seedlings, measures such as artificial light supplement and temperature increase can be taken. Prevent seedling frost injury or overgrowth; cover should be removed properly during rainy days.

The overhead ventilated roof is widely used in hot summer and cold winter areas in China, especially in the hot and rainy summer, which shows its superiority. The principle of the ventilated roof is to set up a ventilation room layer on the roof. On the one hand, the outer layer of the ventilation room layer is used to block the sun, such as a closed or ventilated air room layer, and the sunshade intercepts the sun directly shining on the roof. The radiant heat makes the roof heat transfer twice, avoiding the direct action of solar radiant heat on the enclosure structure, on the other hand, using the effect of wind pressure and hot pressure, especially natural ventilation, the solar radiant heat absorbed by the upper and lower surfaces of the sunshade in contact with the air is transferred to the air with the wind. The greater the wind speed, the more heat the roof takes away, and the better the thermal insulation effect is, the greater the thermal insulation capacity of the roof is. So as to reduce the effect of outdoor heat on the inner surface.
