Since the condenser of the window air conditioner is air-cooled and located on the outside of the wall, if the sun shines directly (especially at 2: 00 p.m. is the peak time of the cooling load required by the room, and the temperature of the outer wall and the surrounding space is also the highest), it increases the tears on and around the condenser, and the heat dissipation effect of the condenser decreases, resulting in an increase in condensation temperature, resulting in an increase in condensation pressure. The cooling capacity of the system decreases, the power consumption increases, the current increases with the increase of load, and the overload protector is overloaded for a long time, which leads to contact sintering, loss of protection function and compressor burnout. The position of the sunshade should not only block the direct sunlight, but also can not block the hot air out of the air conditioner, so that it can release the heat to the atmosphere without hindrance. The distance between the rear barrier and the window air conditioner should be more than 1.5m. The left and right and upper barriers should be left from the air conditioner! Add coffee and above,
A perfect picnic site, first of all needs an empty grass, surrounded by trees sunshade, such a beautiful spring, do not forget to click a Zimple designer dress this season, put this moment of good time and scenery in the photo, often can not help but look at the corners of the mouth ~
The heat preservation work in the greenhouse can be accomplished by using side insulation and top inner insulation curtain (figure 4), as well as internal and external sunshade curtain and top skylight. The heat preservation work can be carried out 2 hours before sunset. Close the top skylight 2 hours before sunset, expand the internal heat preservation, and then gradually expand the internal sunshade and side insulation. All the internal heat preservation, inner sunshade and side heat preservation will be carried out before sunset. If necessary, external shading can also be fully carried out for thermal insulation. When the external solar radiation is less than 300W/m2 (blade stomata closed) and need heat preservation, you can directly turn on internal heat preservation, side heat preservation and internal shading, and close the top skylight at the same time.
There are two kinds of interior design, high-end version is a common conjoined screen design, the back has a through-style air conditioning tuyere, so that the entire center console is extremely flattened. The part of the air-conditioning system uses a physical button panel, which is arranged in front of the sub-dashboard, and the flight-style electronic file handle is also frequently seen in the design of independent brand models. The latest spy photo also reveals a low-profile version, which may be mainly designed for the needs of the travel market. The difference is mainly in the upper part of the central console, where the dashboard changes into a traditional sunshade structure, but still uses a full LCD screen configuration. The multimedia system is an exposed cavity that can be equipped with devices such as a simple radio multimedia player or a taximeter.
In the severe winter weather, the small arch shed in the greenhouse should be covered with a layer of straw buns or covered with quilts to keep warm, and then covered with a layer of film. Add windbreak and anti-freezing barrier. The combination of straw and old film into a cold wall, placed in the north of the vegetable greenhouse, as a wind barrier, can reduce the harm of cold current. When the temperature in the greenhouse 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. When heating, open fire can not be used to prevent smoke damage, it is necessary to set up a flue to put harmful gases outside. Focus on the heat preservation and anti-freezing of vegetables and seedlings in the greenhouse. For eggplant seedlings that are in the early stage of raising seedlings, measures such as artificial light supplement and temperature increase can be taken to prevent frost damage or excessive growth of seedlings; in cloudy and rainy days, the mulch should be properly removed to make the plants see as much light as possible.
Car front sunshade board the car sunshade board can be put outside as long as the front block, because the sunscreen is installed in the car, the sun will shine through the glass into the car, and the aluminum foil will be reflected back to the car by the glass after reflecting sunlight. The sunshade insulation layer absorbs part of the heat, but blocks the heat in the car and heats up the air in the car, which only plays the role of light insulation and non-thermal insulation.
