The present invention relates to a method for controlling a heating and cooling system of a facility cultivation house and an animal husbandry, and more specifically, to a facility cultivation house that grows various crops regardless of season, and an animal husbandry or a fish farm for raising livestock or poultry. The present invention relates to a control method of an air conditioning and heating system that provides a suitable indoor environment for fish farms, which is installed at one side of a facility cultivation house and an animal husbandry and consists of an indoor temperature sensor for detecting an indoor temperature (TI). The heating mode or the cooling mode may be performed by reading the temperature sensed by the indoor temperature sensor; The indoor temperature (TI) detected by the indoor temperature sensor is compared with the minimum set value, the set time, the maximum set value, and judges whether the compressor is operating to control the appropriate indoor temperature (TI) of the facility cultivation house and the cattle farm. It is to provide a control method of the heating and cooling system of the facility cultivation house and the raising house including the step.

In general, the heating of domestically grown house and livestock farm uses hot air heaters, which are inexpensive, as the main means and accounts for more than 95% of the domestic greenhouse heating area.

The main purpose of heating is to keep the indoor temperature at an appropriate temperature in order to increase the productivity of the crop. Heating is to maintain the required temperature of the target space, and in the case of greenhouse heating, it also includes an increase in the geothermal temperature which greatly affects crop growth. .

Hot air heaters are divided into light oil, heavy oil, gas, firewood, and electric hot air heater according to the fuel used. Usually, the capacity is expressed in kcal / hr. As fossil fuel is converted into combustion heat and used for greenhouse heating, various methods are used to recover 15 to 20% of the combustion heat to the outside in the form of exhaust gas and recover the emitted heat.

Hot air heating has a disadvantage that the air is dried and the room temperature (TI) changes because it heats the room to heat the air. In particular, in the case of a plant cultivation house for plant cultivation, the leaves may not be used for crops such as cucumbers and tomatoes that affect growth.

Even when a boiler is used, fossil fuel is used, so the same heating heat is required, and the boiler must be operated continuously to maintain a constant temperature. The consumption of oil is excessive and the economic burden is high in high oil prices. . In order to maintain the heating heat, there is a problem that the house should be installed in double, triple, quadruple with insulation.

In addition, during the summer, excessive high temperature may damage the growth and growth of crops and living organisms. Therefore, for cooling, the air conditioner and cold water generator are installed separately, or the facility is maintained at an appropriate temperature with a ventilation fan. It is a situation that cooling is required for temperature, and for this purpose, there is a problem that a separate cooling system must be provided.

The present invention has been made in order to improve such a problem, the cooling and heating system that provides a constant temperature and warmth to the facility cultivation house and the raising house by using a groundwater to maintain a constant temperature regardless of the season consists of one unit The present invention provides a control method of a heating and cooling system, and furthermore, includes an energy saving system in the facility cultivation house and a cattle farm, and an object thereof is to provide a control method of an easy and stable heating and cooling system.

Hereinafter, a configuration of the present invention will be described with reference to the accompanying drawings.
