Although the solar greenhouse has a very good thermal insulation performance, but from the point of view of safety, heating equipment is still an important factor. The southern part of our country generally does not need to heat up, but if we encounter bad weather continuously, we still need to use the energy stored in the greenhouse itself, otherwise it will not be able to meet the growth of vegetables. Therefore, whether in the south or north, heating equipment has always been a necessary protective measure. The technical aspect requires that in the equipment configuration of solar greenhouse, the configuration of thermal insulation equipment should be demonstrated in great detail. Of course, the work of Bengbu vegetable greenhouse needs the cooperation of a variety of equipment, with the increasing temperature requirements, especially in autumn and winter production, external sunshade system, internal thermal insulation system and window opener and fan, wet curtain and other equipment need to be applied. For more information about the cost of vegetable greenhouse in Bengbu, please contact Minghao greenhouse Engineering Construction Company directly.
Near Xiaoshan Volkswagen lossless car audio modification, because the car audio is mostly installed in the upper part of the dashboard, in order to avoid sunlight, the effect of using sunshade is better. If the door and window sealing strip is not strict, it should be replaced, otherwise the loudspeaker is easy to rust and damage, or even cause short circuit to burn the main engine. The specific heat of the circuit board and plastic components in the car audio mainframe is different, so it is affected by the temperature change to a different extent. In the scorching sun, it is good to use the sunshade to resist the scorching sun and avoid the direct sunlight.
1, the choice of car sunshade material is now the most on the market is aluminum film pvc material, aluminum film material effectively reflect light and internal PVC bubbles effectively insulate the conduction of thermal energy, can play the role of thermal insulation and cooling. So the size of the aluminum film and the thickness of the pvc material determine the effect of use. When buying this kind of sunshade, it is best to choose a model with a sucker, although it will take more time to place each time, but the model without a sucker is more likely to fall from the inside of the glass, which loses the meaning of using sunshade. It is recommended that we try to choose thicker ones when buying, and the effect is definitely better than the ordinary ones.
The concrete structure built in 1963 is a huge thermal bridge, and the limestone exterior walls and lack of insulation pose challenges to the energy consumption of the building. Skylights with fixed sunshades provide passive heat and natural light for the four-story atrium. Program-controlled blinds fall at night to reduce heat loss.
Chinese automobile media reporters have tested the special sunshade film affixed to the car window, and the conclusion shows that it does have a certain sunshade and heat insulation effect. However, this kind of sunshade film will seriously reduce the light transmittance, resulting in poor vision at night, so it is not recommended to install the sunshade film on the windshield. Other side windows can be mounted with sunshade film if necessary, although the shading effect is not necessarily obvious, at least it can better protect the privacy of passengers.
(1) in order to avoid heatstroke during the construction period, sunshades and rest rooms should be set up at the construction sites of each shift at the construction site, and each construction personnel should be provided with a towel in each rest area. The construction personnel should go back to the rest area every 2 hours to have a rest for 15 minutes to prevent unnecessary dangerous accidents. Ice cubes, tea, towels, anti-heat medicine, etc., in the lounge.
Under the premise that Ningdu meets the design requirements of the building, adding external sunshades, awnings and appropriately increasing the length of the southward balcony can play a certain sunshade effect. Heat-reflecting fabric curtains coated with metal film are arranged on the inside of the window, which has a decorative effect on the front, forming a less mobile space layer about 50mm thick between the glass and the curtains. In this way, a good effect of thermal reflection and thermal insulation can be achieved, but the direct lighting is poor and should be made into a movable type. In addition, installing blinds with certain thermal reflection on the inside of the window can also obtain a certain thermal insulation effect.
