More particularly, the present invention relates to a system for supplying cold water directly to an upper portion of a livestock using an air duct connected to a fan coil unit and a branch pipe connected to the fan duct, And the water is supplied to the inside of the house by constructing a combination of the methods of supplying cold water and cold water for the reduction of high temperature stress in the summer season and supplying the heating and hot water for increasing the feed efficiency in the winter season And to a simultaneous supply and reception system for cooling and heating indoor and outdoor hot water.
Poultry industry has been steadily growing due to the increase of meat consumption, and it accounts for 26% of domestic agriculture and livestock industry. As a result, the cages have been developed to increase the scale and the degree of sealing to increase the production efficiency.
However, due to the generalization of high-density dense breeding, the pattern of disease occurrence becomes complicated. As a result, chicken with low temperature adaptability compared to other animals has high mortality due to high temperature stress during the summer, weight loss of broiler chickens, Difficulties are growing in the management of the breeding environment.
As a result of the warming of the climate, the cooling load of the summer season has been continuously increasing, and the high temperature damage of the livestock facility has also increased, resulting in 526 farms in 1,766 farms and 81 farms in 79 farms.
The house is a kind of energy-free agricultural facility. Since it mainly operates oil heater in winter season heating, there is a large heating cost. In order to reduce heating cost, poultry farms that are provided with minimum heating and minimum ventilation are increased, It is continuing.
In addition, the house relies on ventilation and fog cooling to reduce the high temperature in the summer. Some farmers supply ground water to lower the temperature of the drinking water or put some ice directly into the drinking water tank, but the effect is limited.
Therefore, in order to improve productivity and improve management of livestock farmers, it is required to take measures for summer season and winter season in consideration of economical efficiency such as energy cost and specification characteristics of seasonal species.
Therefore, according to the present invention, by using an air duct connected to the fan coil unit and a branch pipe connected thereto, cold water is directly supplied to the upper part of the livestock, and cold water is produced in the drinking water tank connected to the heat pump, The purpose of this study is to develop a high-efficiency environmental improvement system that can simultaneously supply cold water and cold water for summer stress reduction, and supply hot water and hot water for winter feed efficiency enhancement.
According to an aspect of the present invention, there is provided an in-building cooling / heating / cold / hot water supply concurrent system, comprising: an air mass / heat pump for producing cold / hot water for housing cooling / A heat exchanger connected to the air objective heat pump for making cold and hot drinking water through heat transfer from the cold / hot water produced by the air / matter heat pump; A drinking water tank connected to the heat exchanger for storing the cold and hot drinking water; A cold water supply water pipe connected to the drinking water tank for supplying cold and hot drinking water into the housing; A storage tank connected to the air objective heat pump and storing cold / hot water generated by the air / object heat pump; And a cold air duct disposed in the housing to supply cold air to the inside of the housing using cold / hot water stored in the thermal storage tank.
The system further includes a water supply pipe for moving the cold / hot water supply pipe and the cold / hot air duct vertically, and a cold / hot air duct vertical movement device.
Here, the water supply pipe and the hot / cold air duct vertical moving device may include at least one water pipe connected to the water supply pipe and the hot / cold air duct perpendicularly to the longitudinal direction of the hot water pipe to maintain the height of the water supply pipe and the hot / Steel wire; A winding motor that winds or unwinds the steel wire with power; And at least one drum located in a path of the steel wire connected to the water supply pipe and the cold / hot air duct from the winding motor, and rotated so that the steel wire is easily unwound or rolled.
The system may further include a three-way valve for selecting a cooling / heating / cold / hot drinking water path located in a pipe at a point where the air / object heat pump is connected to the heat exchanger and the heat storage tank.
In addition, a fan coil unit may be further provided between the heat storage tank and the cold / hot air duct to generate cold / warm air using the cold / hot water stored in the thermal storage tank and supply the cold / hot air to the cold / hot air duct.
The cold / hot air duct may further include a plurality of branch tubes for local cooling / heating for locally supplying cold air generated by the fan coil unit to the livestock. The cold / hot water supply pipe supplies cold / And a plurality of nipple water dispensers.
Further, it is preferable that the hot water circulation pump further comprises a circulation pump between the air mass heat pump and the three-way valve, and between the heat storage tank and the fan coil unit, and between the heat exchanger and the drinking water tank, and between the drinking water tank and the cold water drinking water supply pipe May further include circulating pumps for drinking cold water.

According to such a system for supplying cold water for drinking and drinking water and drinking water for cold and hot water, there are a local cooling and heating system for supplying hot and cold water directly to the upper part of the livestock and a drinking water tank connected to the heat pump for generating cold water in the summer and hot water in the winter, It is possible to provide a high-efficiency environmental improvement system for reducing the high temperature stress in the summer season and increasing the feed efficiency in the winter season.
In addition, since the housing cooling and heating device and the cold and hot drinking water supply device are not separately constructed, the scale of the system can be reduced.
In addition, by adjusting the height of the branch pipe and the nipple water dispenser for local cooling and heating according to the growth state of the livestock using the water piping and the cold / hot air duct up-and-down moving device, energy cost can be saved as compared with the entire air- It is possible to supply.
In addition, hot water supply in the winter season can increase the body temperature of the poultry to prevent excessive feed intake, prevent respiratory diseases due to low temperature, and supply cold water in the summer season to induce additional negative water to supply moisture required for respiratory heat loss of chicken And promoting feed intake, thereby increasing the weight of broiler chickens and improving egg shell quality of laying hens.
In addition, by setting the reference temperature of the regenerating tank upper / lower water temperature, the upper / lower water temperature of the drinking water tank, and the upper / lower temperature inside the house, the heat pump, fan coil unit and circulation pump can be automatically turned on / Manpower for management is unnecessary, and the housing can be managed more accurately and efficiently.
In addition, due to the prevention of diseases, the production of poultry industry can be increased, so that the domestic self-sufficiency rate of poultry can be improved and the profitability of poultry farmers can be improved.
