Air source heat pumps not only have the characteristics of uniform heating and fast heating speed, but also can intelligently control the temperature of vegetable greenhouses, which is suitable for constant temperature heating of vegetable greenhouses. Air source heat pump heating will usher in more market opportunities in greenhouses, vegetable greenhouses, flower greenhouses and other fields.
Shandong has always been a major province of animal husbandry and agriculture. Considering the current policy environment and the actual temperature control needs of greenhouse crops, in order to ensure the supply of agricultural products in winter, reduce coal-burning pollution in agricultural production, and market development trends, many agricultural greenhouse heating systems have been changed to air source heat pumps.
1. Safety and environmental protection
Air source heat pumps work by operating compressors, absorbing heat from the air and then transferring heat to water. Compared with traditional coal-fired heating, air source heat pumps are convenient. Since coal burning is time-consuming and labor-intensive to burn coal continuously, air source heat pumps only need to set the temperature with one button, and the machine will automatically start and stop, which is convenient and labor-saving.
2. Efficient and stable, energy-saving and money-saving
Air source heat pumps are a type of equipment that does not burn coal or gas at all. It absorbs heat from the air to make hot water. It can be heated by heating terminals. Its thermal efficiency is very high. The thermal efficiency of common coal-fired boilers is only about 85%, and the thermal efficiency of air source heat pumps can reach more than 200%, up to 400%. The power consumption of heat pumps is 1 degree, and they can "carry" several times the heat energy from the air. After the heat pump provides a large amount of hot water, a large number of fan coils and hot water pipes are set up in the greenhouse, which can significantly increase the temperature in the greenhouse and provide a perfect growth environment for greenhouse crops.
3. Intelligent management and cost saving
Using modern greenhouse heating and air source heat pump heating systems, make full use of these advanced technical facilities, scientifically and intelligently control the growth characteristics and day and night temperature differences of greenhouse crops, improve crop yield and quality, reduce labor costs, and increase the economic value of crops. Different personalized heating methods can save a lot of unnecessary heat loss. Reduce greenhouse heating costs. Generally speaking, it is simple to operate and saves money.
For example, the temperature of the root (canopy) determines the growth of some crops. Then, heating pipes are set near the roots of the crops to ensure that the canopy temperature is controlled at the required state with minimal energy consumption. In addition, using air source heat pumps to lay "floor heating" in the soil of vegetable greenhouses can effectively solve problems such as large temperature differences in winter, low soil temperature, slow crop growth, and poor development. Compared with the traditional overall heating mode, this personalized heating mode based on the growth characteristics of crop varieties saves a lot of greenhouse heating costs.
