In the internal thermal insulation system, when the greenhouse or indoor temperature drops to the set low temperature limit at night, the thermal insulation quilt is turned off, the heat preservation of the greenhouse is strengthened, the ground radiation heat loss is reduced, the heating energy consumption is reduced, and the operating cost of the greenhouse is greatly reduced; the shade curtain can be opened during the day to make the greenhouse fully daylighting. The working principle is the same as that of internal sunshade, which is made of a lightweight quilt that does not absorb water and weighs between 100 and 150 grams.
(3) the combination of glass canopy and stainless steel sunshade makes use of the characteristic that stainless steel is a poor conductor of heat, and takes away the solar radiant heat through the air flow caused by hot pressure and wind pressure between the two, so that the canopy system can play a role of heat insulation. make the building more energy-efficient.
The cab. The flat head can be turned over, the torsion bar type overturning mechanism, the driver seat, the middle seat and the helper seat are arranged in the front row of the driving room. The driver seat can be adjusted back and forth, and the seat back angle can also be adjusted. There are berths in the back row with insulated carpets, sundries, quartz clock, cigarette lighter, receiver, sunshade, inner rearview mirror and curtain frame. Both doors are equipped with locks, door glass can be raised and lowered, triangular window and rear window glass can be opened. The front window is equipped with an electric wiper and washer, and the door is equipped with an external rearview mirror. There is instant wind, air conditioning optional.
The richness of the configuration is also an important factor to attract the review team. They believe that at half the price of a luxury car, it will have a full-time all-wheel drive, front and rear seat heating, wireless charging and a second row of private sunshades. In the light-colored interior version, the matte wood-like decoration carves a half-moon on the passenger side of the dashboard and then extends precisely to the upper part of the door, visually connecting the entire front row.
It is necessary to do a good job of heat preservation at night and ventilation and humidity reduction during the day. The night temperature in early spring is still low, which needs to be covered with grass curtain, sunshade net, non-woven fabric or multi-layer mulching; the temperature rises rapidly during the day, coupled with the current high humidity in the field, so it is necessary to timely control and adjust the indoor air humidity and temperature in the shed. On a sunny day, after the temperature picks up after 08:30, ventilation should be carried out gradually, and the mulch such as non-woven fabrics should be removed in time to increase the light; the shed should be closed and the warmth should be covered before 4 p.m. In case of cloudy and rainy weather, it is still necessary to properly ventilate during the day to reduce the humidity in the shed. In addition, in the alternate season of late winter and early spring, the weather changes greatly, so we should pay close attention to the weather changes to prevent the occurrence of late spring cold. After the middle of April, the average temperature is stable above 15 ℃, which can remove the inner shed, prolong the opening time of the outer shed, increase the light time and intensity, reduce the humidity in the shed, and control the occurrence and prevalence of diseases such as leaf mold and gray mold.
