Description

Livestock Cooling and Heating System {heating and cooling system for a barn}

The present invention relates to a livestock cooling and heating device, and more particularly, to a livestock cooling and heating device for cooling and heating a livestock house, such as a poultry farm, a pig farm.

In general, the farms for farming facility crops or livestock breeding houses maintain an appropriate temperature because they have a relatively large effect on the growth of crops and livestock. In particular, when the temperature inside the barn for breeding pigs or chickens is too high or too low, feed intake is lowered, delivery rate is lowered, and group mortality occurs.

Pig deaths in South Korea are 620,000 head per year (11.9%), and pigs are mainly caused by pig temperature, humidity and air pollution. By controlling temperature and air pollution, which account for 70% of pig mortality, mortality can be reduced to less than 5%.

Therefore, a cold or heating apparatus is installed in a cold or cold period to maintain the indoor temperature of a barn in an appropriate state.

Republic of Korea Utility Model Registration No. 410652 discloses a temperature and humidity control device for the barn. The disclosed temperature and humidity control device is installed inside the case, and includes a water tank for water storage, a heater and a cooler for heating or cooling water supplied from the water tank, a pump for supplying heated or cooled water, It is associated with the electric pump, and provided with a plurality of nozzles provided in the air outlet of the case, a blower for diffusing the water and air discharged through the nozzle and the air outlet into the room.

The temperature and humidity control device configured as described above has a structure injecting water directly to the barn, it is difficult to expect the effect of long-term cooling and heating.

Patent No. 0690078 discloses a heating and cooling device for concentrated livestock using groundwater, and Patent Publication No. 2002-0091611 discloses an air conditioning and air purifying device using a thermal energy of geothermal heat and exhaust air. In addition, Utility Model Registration No. 0238733 discloses a technical configuration of an in-house temperature control device and an air purification system using a heat exchanger.

However, as described above, the air-conditioning and heating device for the concentrated livestock in the same livestock air conditioner uses groundwater as an auxiliary heat source, and thus, the structure is relatively complicated, and thus, it is difficult to install it in the unit house complex. In particular, since groundwater is used as a secondary heat source, it is difficult to efficiently manage temperature, and there is a problem in that groundwater is secondaryly contaminated.

The present invention is to solve the problems as described above, can significantly reduce the cost of cooling, heating the barn for raising livestock, such as pigs, chickens, heating and heating of the barn can increase the design freedom according to the barn In providing a device.
