The present invention relates to a heating and cooling device for concentrated livestock, and more particularly, by cooling or heating according to seasons to maintain an optimal temperature in a facility house or barn, as well as by using low-temperature heat medium such as groundwater and ice storage water. The present invention relates to a heating and cooling device for concentrated livestock, which can dramatically reduce the energy cost required for heating and cooling by generating cold air or generating hot air by a small amount of high temperature heat medium.

In recent years, the use of facility houses for cultivating various crops such as vegetables, fruits, mushrooms, etc., regardless of the season, as well as the house for raising chickens, ducks, etc. is increasing, and the indoor temperature of these facilities is appropriately increased. By maintaining it, the crops and livestock can be more effectively promoted.

In general, for heating and cooling the facility house or barn, in winter, the heater is installed to increase the room temperature above the outdoor temperature, or in the summer, by installing a separate air conditioner to lower the outdoor temperature.

1 is a view for explaining the principle of operation of the hot air heater used in many agricultural facilities at present, as the fuel is burned in the burner so that the hot air gas is discharged by turning the communication two to four times and the wind by a conventional blowing fan Is a device that heats the heat of the hot wind in the communication with the air to heat the hot air by colliding with the surroundings of the communication.

This method is an air-cooling method that exchanges heat of hot air with air, and since a sufficient heat exchange is not performed, a large amount of fuel is consumed as a large amount of exhaust gas is discharged through the chimney with a temperature of about 250 to 310 ° C. Of course, the environmental pollution caused by the exhaust gas is large.

In addition, a conventional hot water boiler is a device for exchanging heat by water-cooling by filling water with a higher specific gravity than air because the water is filled instead of air around the combustion chamber passing the hot wind gas, 300-400% higher heat exchange efficiency than the hot air heater In addition to the low temperature of the exhaust gas as low as 80 ~ 130 ℃ as well as the amount of heat energy and the exhaust gas is small, there is an advantage that can save fuel.

However, since hot water must be installed through a heat exchanger in an agricultural facility such as a facility house or barn, the hot water must be passed through, so plumbing must be installed to allow the hot water to flow to the place to be heated. Due to such factors as facility and labor costs, they were practically not readily available to farmers.

However, in manufacturing the heat sink assembly 4 as described above, the pipe 5 and the U-shaped pipe fitting 8 having the heat dissipation fins 6 must be integrally manufactured by thermite welding. In addition, separate fixing plates 9A and 9B must be installed on the inner and outer surfaces of the heat dissipating tube 7, which is very demanding and results in an increase in manufacturing cost.

In addition, since it is necessary to pay close attention in the welding operation, it requires a high level of skill, and also causes a great deterioration in productivity due to the occurrence of defects such as water leakage.

In addition, since parts such as boilers, valves, and pipes constituting the air conditioner are assembled on-site, the product price is greatly increased due to various problems such as after-sales service including a separate labor cost. It was a problem.
