Description

Greenhouse

technical field

The utility model relates to the field of agriculture, in particular to a greenhouse breeding house.

Background technique

In summer, the temperature of greenhouses and breeding houses is generally 7 to 8 degrees Celsius higher than that of ordinary houses. High temperature weather is a period of high incidence of animal and plant diseases, and cooling is very important. Some farmers sprinkle water on the roofs of greenhouses and breeding houses, and ventilate more in the morning and evening. The effect is not good, and the modern cooling tool is to use air conditioners, water curtains, etc. to reduce the temperature of greenhouses and breeding houses. However, due to the high cost of air conditioning, the core component of the water curtain type is a direct evaporative heat exchanger (wet curtain), whose actual heat exchange effect is close to 100 times the surface area, and can achieve a cooling effect that is 4-10 degrees lower than the outside world. Compared with traditional central air conditioners, it can save more than 80% of equipment investment and 80% of electricity consumption, and has the advantages of installation, maintenance, easy operation, extremely low operating costs, and durability.

However, the water curtain type is suitable for use in a closed environment. The outdoor fresh air is filtered by the cooling fan. After cooling, it is transported to the room and the fan also discharges the indoor smelly and turbid air to the outside. On the premise of paying attention to environmental protection, the exhaust gas is discharged to the outside. It has made the road of aquaculture more and more difficult. In addition, water curtain greenhouses and breeding houses are not suitable for winter heat preservation requirements. In order to increase the oxygen content of the air so that ventilation and cooling are not conducive to winter use.
