Study On Design And Construction Of Inner Thermal Insulation Solar Greenhouse And Its Properties

By making comparison with inner thermal insulation solar greenhouse before improvement and the improved inner thermal insulation solar greenhouse in terms of air temperature, wall temperature and relative humidity, through the experiments, the results show that in terms or temperature, indoor air temperature of the improved inner thermal insulation solar greenhouse was higher than inner thermal insulation solar greenhouse before improvement, the average temperature of the improved inner therma insulation solar greenhouse was higher than inner thermal insulation sol greenhouse before improvement, the average night temperatures of t improved inner thermal insulation solar greenhouse was higher than inn thermal insulation solar greenhouse before improvement, the improved inn thermal insulation solar greenhouse in December, January and February indoor average temperature were 17.1℃,17.5℃ and 17.8℃, the average ni temperature is 12.5℃,12.6℃ and 12.7℃ respectively, its minimum month average temperature were 7℃,7.1℃ and 7.2℃ respectively, inner therm insulation solar greenhouse before improvement in December, January as February of indoor average temperature were 14.3℃,14.6℃ and 14.8X℃ average temperature at night was 9.4℃,9.6℃ and 9.9℃, its average month minimum temperature was 5℃,5.1℃ and 5.2℃ respectively; In terms of temperature, sunlight greenhouse were wall lateral heat transfer, the deep the wall, temperature fluctuations is flat, the improved inner therw insulation solar greenhouse in 20 cm,40 cm,80 cm depth of wall ave temperature are higher than inner thermal insulation solar greenhouse before improvement, in December, the improved inner thermal insulation solar greenhouse in the average wall temperature of 20 cm,40 cm,80 cm was 2.7 t 2.9℃,1.4℃ respectively higher than inner thermal insulation solar greenhoun-before improvement; In January, the improved inner thermal insulation solar greenhouse in the average wall temperature of 20 cm,40 cm,80 cm was 2.9℃, 2.2℃,1.4℃ respectively higher than inner thermal insulation solar greenhouse before improvement; In February, the improved inner thermal insulation solar greenhouse in the average wall temperature of 20 cm,40 cm,80 cm was 3℃, 2.7℃,1.5℃respectively higher than inner thermal insulation solar greenhouse before improvement, in terms of relative humidity, the average relative humidity of inner thermal insulation solar greenhouse before improvement was 3.6%,4%,4% higher than the improved inner thermal insulation solar greenhouse, so performance of the improved inner thermal insulation solar greenhouse was better than inner thermal insulation solar greenhouse before improvement, the improved inner thermal insulation solar greenhouse is feasible in the promotion of solar greenhouse.The second part test, 5 basic same the improved inner thermal insulation solar greenhouses ventilate respectively 0,3,5,10,15 minutes before the curtain closed at back slope of the greenhouse. Then research them in the light, temperature, relative humidity, According to the requirements of the ecological environment of cucumbers and tomatoes, the Inner Mongolia region the main production of the sunlight greenhouse vegetables.Select the most appropriate ventilation time, which is 5 minutes.
