Greenhouse cooling and heating facility system using a pressure pump {air-conditioning and heating facility system of greenhouse using press type pump}

The present invention relates to a greenhouse cooling and heating equipment system using a pressure pump. More specifically, in implementing cooling and heating of a greenhouse, equipment that requires the supply of a heat source (cold and hot water supplied to the required area) is simple. It is a facility system that has a compact structure and can provide cooling and heating with a single heat source tank. It prevents water hammer phenomenon and pump sticking phenomenon that occurs in each pipe, and is a pressure type system that enables efficient supply of fluid energy. This relates to a greenhouse cooling and heating system using a pump.

In general, greenhouses are equipped with facilities that enable cooling and heating, but most existing facility systems include boilers, heat pump heat source equipment, circulation pumps, fan coils, side/floor heating pipes, constant flow valves, differential pressure valves, Since equipment consisting of many and diverse parts such as electric valves, heat exchangers, strainers, flexible joints, checks and flanges, and piping are required, the number of parts and materials is bound to increase.

Moreover, due to the difficulty in operating and managing the stable start and stop of pumps, the phenomenon of water hammer frequently occurs in each pipe, and the pumps do not operate alternately or the circulation pumps of heating equipment such as boilers operate for a long time. As a result, the sticking phenomenon in the pump continues to worsen.

In addition, since a large number of parts and materials are required for equipment to implement cooling and heating, there is a serious waste of energy due to excessive consumption of unnecessary power.

In this hot water flow process, the heat source can be maintained efficiently while minimizing the energy loss of the heat source, and the cost of heating and cooling operation and the cost of generating energy from the heat source can be significantly reduced.

This automatic water supply device uses a pressure sensor to detect pipe pressure that changes depending on the flow rate of city water, compares it to the target pressure, changes the rotation speed of the pump through instructions from the control device, and simultaneously controls the pumps in parallel. The required water pressure can be met by starting and stopping.

The automatic water supply device can provide water supply at an appropriate pressure through the control device. The control device may be configured as an individual inverter type or a single inverter type, and the individual inverter type control can control multiple pumps, for example. A single inverter type control can control, for example, one pump.

Although not shown, a color LCD touch panel display with a GUI (Graphical User Interface) may be applied to the individual inverter type or single inverter type, and such a display can help you easily see the operating status of the inverter. Due to the high safety and precision through multi-control and small pressure deviation, it is possible to control the water pressure at a constant level, save power through optimized operation, and alternate operation based on the actual pump operation rate is also possible. Of course, the piping applied to the automatic water supply device may be structured in the form of a confluence pipe.

In addition, the above-mentioned individual inverter type or single inverter type is not shown in the drawing in addition to controlling the rotation speed of the pump according to load changes, but the compact structure allows for saving installation space, especially due to the built-in noise reducer and harmonic suppressor. Noise reduction and power factor improvement can be expected, and driving safety can be maximized. Of course, the individual inverter type or single inverter type does not require the installation of components such as a separate control panel or control valve.

The noise reducer is a device designed to not only reduce noise generated from electronic devices of a control device so as not to affect the operation of the automatic water supply device, which is another electronic device, but also block the influence of noise on the automatic water supply device. It can be achieved with an electromagnetic compatibility.

In addition, the harmonic suppressor is installed at the DC link terminal of the inverter, for example, and consists of a reactor that can effectively suppress harmonics by reducing the content of harmonics to the range of 30 to 40%. You can.

Regarding the input current of the inverter, due to the characteristics of the rectifier unit, for example, the 5th and 7th harmonics may have a large distorted waveform, which ultimately has a negative effect on the power supply unit and becomes the cause of the problem of worsening the power factor. , the harmonic suppressor described above can be expected to not only suppress these harmonics but also improve the power factor.

The above control device can have the effect of extending the life of the pump through precise control, and furthermore, it has an anti-icing means to prevent the pump from freezing, an idling prevention means to prevent idling, and an external communication support function. It may be configured to include an Internet control means for an Internet control function.
