Agricultural greenhouses adopt air source heat pump heating, daily operation energy consumption only 30 KWH! 2018-12-29

agricultural greenhouse

In early 2018, Tianjin dealer at a river management office in Wu qing made a nearly 700 vegetable greenhouses heating projects, after field testing, at 15 ℃ condition, indoor temperature 20 ~ 25 ℃, the running energy consumption is only 30 KWH/day.


Under the Chinese national policy of reducing and banning coal, some traditional greenhouse heating equipment has been gradually eliminated and banned, such as coal burning and oil-fired boilers. Heating methods such as coal burning and oil-fired boilers. These heating methods require some combustibles such as coal and fuel to be used, which not only consumes more energy but also causes serious pollution. Taking a coal-fired boiler as an example, according to the greenhouse span of 8 meters and a length of 80 meters, the greenhouse of a volume of 1383m³ is calculated by using a coal-fired boiler to increase the temperature in the greenhouse by 3.0℃. 1 ton of coal. Not only that, but when such coal-fired heating stove equipment is in operation, it needs to be guarded by personnel and the labor cost is also high.

After the installation of the project, it will enter the official operation stage at the end of January. The actual measurement shows that the ambient temperature is -15 °C, the set temperature is 55 °C, the actual outlet temperature is 51 °C, and the indoor temperature is 24 °C, which satisfies the greenhouse. Vegetable growth temperature requirements. After nearly one heating season, the customer is very satisfied with the heating effect, and the temperature in the greenhouse is always between 20 and 25 °C. In terms of operating energy consumption, according to customer feedback, the equipment running time is about 8 to 10 hours, and the daily energy consumption is about 30 degrees.

The customer said, “I wanted to use coal-fired boilers at the beginning, but now I ban coal, so I chose air with higher initial investment but lower energy consumption. From the perspective of operation, the effect of heating is very good, greenhouse The growth of the vegetables is also very good. Overall, the operating costs are quite satisfactory, and there is no problem during heating."

air source heat pump unit

Air source heat pump is used as a heat source to heat greenhouse greenhouses. It is necessary to pay attention to understanding the properties and growth rules of crops, such as the temperature requirements of different types of vegetables. Appropriate optimization adjustments are needed in design schemes, construction and installation, and control systems. In addition, the insulation of vegetable greenhouses is also very important, which can reduce the loss of heat and reduce operating costs. The air can be ultra-low temperature heating and cooling machine, and the heating demand of a vegetable greenhouse that can meet one mu of land can also realize the free combination of 16 sets of equipment to realize intelligent centralized control.

The air source heat pump has the characteristics of low noise and small vibration, and is very suitable for heating and cooling needs in schools, hospitals, shopping malls, villas, greenhouses and other large places. Under the background of the country's implementation of clean heating, it is worth promoting and applying nationwide.
