Hog house fresh air, temperature and humidity regulation and control system

Abstract

The invention discloses a hog house fresh air, temperature and humidity regulation and control system. The hog house fresh air, temperature and humidity regulation and control system comprises a roof, a plastic film greenhouse, a supporting member, a fermentation bed and a platform, wherein periphery of a hog house is enclosed by brick walls, the wall of the hog house is provided with a wall interlay air channel, the connection portion of the wall interlay air channel and the hog house is provided with an air supply outlet, the upper portion of the hog house comprises the roof, the supporting member and the plastic film greenhouse, the upper portion of the plastic film greenhouse is provided with a sunshading screen cloth, the roof is provided with an electrical air exhaust port and an axial-flow blower fan, a shady face wall of the hog house is provided with a ventilation window, the fermentation bed and the platform are at a central position of the hog house, soil below the fermentation bed and the platform is provided with heat exchange air channels, and ground portions of the heat exchange air channels are provided with air inlets and filter nets. A summer air exchange and heat radiation process is a natural convection heat exchange process, forced mechanical air exhaust is not necessary, outdoor hot air is cooled and dehumidified through the ground soil and is then sucked into the hog house, fresh air exchange is further realized, no energy consumption is realized in the process, and the cooling effect is excellent.

Description

technical field [0001] The invention relates to the field of pig raising production equipment, in particular to a pig house fresh air, temperature and humidity control system. Background technique [0002] Livestock dormitories have certain requirements on temperature and humidity. Generally, the optimum temperature for fattening pigs is about 20°C. In the modern breeding industry, in order to control the excessively high temperature in summer, wet curtains and mechanical forced ventilation are used to cool pig houses, replenish fresh air and maintain the concentration of carbon dioxide. It needs to consume electric energy, and at the same time, the outdoor hot air is cooled by the wet curtain to a limited extent. Fan noise also affects livestock. Especially if there is a power outage, it will affect the operation of the system. If the fermentation bed method is used to raise pigs, the temperature in the pig house is higher in summer. If the heat in the pig house cannot b...

AI Technical Summary

Problems solved by technology

Especially if there is a power outage, it will affect the operation of the system

If the fermentation bed method is used to raise pigs, the temperature in the pig house is higher in summer. If the heat in the pig house cannot be discharged in time, it will cause high temperature and cannot breed
