Description

Sub-area temperature-controlled heat pump temperature adjustment device in the livestock house

technical field

Traditional livestock houses, such as chicken houses and pig houses, generally lack temperature and humidity adjustment systems, and usually only rely on the insulation and ventilation functions of the building itself, and there are no measures for humidity monitoring; The farrowing sows and piglets in the pig house are in the same farrowing pen and in the same house, but the sows are afraid of heat, and the piglets are afraid of cold. However, sows need a lower ambient temperature (the suitable temperature is 18-22°C). In the current hot summer and cold winter climate zone in China, the heat stress caused by the high temperature in the farrowing pig house has a greater impact on the reproductive performance of sows. , while high temperature has little effect on the survival rate of piglets; the cold stress of piglets caused by low temperature in the farrowing sow house in winter has a greater impact on the survival rate of piglets, while low temperature has no obvious effect on the reproductive performance of sows.

It is more difficult to control the winter and summer environment in the farrowing pig house that is suitable for the temperature of sows and piglets at the same time. At present, very few farrowing sow houses use dripping water to cool down. If the dripping water on the head and neck of the sows does not increase the local ventilation equipment, the cooling effect will be poor. volume of space. Although only reducing the body temperature of the head and neck of sows with dripping water can relieve heat stress to a certain extent, the degree to which this cooling method can relieve heat stress and affect reproductive performance of sows is not yet clear.

The prior art once recorded a facility that uses a radiant roof to locally cool adult pigs, but the existence of the radiant roof will have a certain impact on the ventilation in the house, and it is not suitable for a farrowing pig house.

How to control the temperature in different areas in a livestock house to meet the temperature needs of different individuals has become a technical problem that needs to be solved urgently.
