The temperature suitable for the growth and development of crops is usually between 20 and 30 ℃, and the humidity is usually between 40 and 80 percent. The greenhouse creates a closed independent environment for the growth of crops, and in the independent space, the diffusion and loss rate of carbon dioxide is slowed down, so that a certain heat preservation effect is achieved; and the temperature and the humidity of the independent environment are adjusted to create a cultivation environment suitable for the growth of crops, so that the crop yield can be effectively improved, and fresh vegetables can be produced all the year round.

Among traditional big-arch shelter management technique, thereby can burn charcoal in the big-arch shelter usually and improve big-arch shelter temperature, improve air humidity through artifical watering. The mode is more original, the time cost of investment is higher, and the temperature and humidity adjusting capacity is limited.

Therefore, Chinese patent with publication number CN104793670A discloses a greenhouse medium temperature and humidity control system, which is divided into a heat preservation part, a heating part and an indoor temperature and humidity control part; the heat preservation part adopts two layers of supports for supporting heat preservation films and is matched with two sets of rolling shutter machine systems; the heating part consists of a wind driven generator and a water storage tank. According to the scheme, the two-layer heat-insulating film structure is built during the construction of the greenhouse, and the two sets of rolling shutters are matched, so that the greenhouse can cover two layers of heat-insulating quilts and the like, the heat-insulating performance in winter is good, the heat-insulating quilts can be freely folded and unfolded, and the daylighting performance of the greenhouse in daytime is not affected.

But the scheme can only regulate the temperature of the whole greenhouse on the whole; the adjustment is not fine enough, and the temperature and humidity in each area are easy to be inconsistent due to the large space in the greenhouse, so that each area needs to be adjusted independently.

Therefore, a temperature and humidity control device capable of independently adjusting each area in the greenhouse is needed.

Because the water in the auxiliary water delivery pipe flows rapidly, the pressure in the auxiliary water delivery pipe is relatively small, and the air enters the auxiliary water delivery pipe through the check valve. After the air is injected into the auxiliary water delivery pipe, the air in the auxiliary water delivery pipe is increased, and the atomization effect is improved. Through sneaking into the air, reach better atomization effect, if the air that lets in is not hot-blast, then, water absorbs the heat at the atomizing in-process, can also play for the radiating effect of big-arch shelter.
