With the continuous deepening of energy-saving and emission reduction policies, the continuous progress of technological innovation, and the continuous improvement of living standards, people's awareness of environmental protection has become stronger and stronger. Nowadays, the use of high-energy-consuming and high-pollution equipment such as oil-fired boilers and coal-fired boilers is strictly restricted or even prohibited. High-efficiency, energy-saving, safe and environmentally friendly equipment has become a practical need, and air source heat pumps have emerged in this environment.
So far, air source heat pumps have been successfully used in floor heating, constant temperature of electroplating liquid in electroplating plants, heating and constant temperature of high-temperature hot water in slaughterhouses, high-temperature hot water in hotels, high-temperature hot water in schools, high-temperature hot water in hospitals, seafood drying, fruit and vegetable drying, tobacco leaf drying, Chinese medicinal materials drying, wood drying and other fields.
1. Industrial energy-saving applications
As we all know, the conventional hot water temperature is generally below 55°C, but industries such as electroplating plants, slaughterhouses, printing and dyeing factories, and hardware factories need to meet high-temperature hot water of up to about 85°C. According to the survey, the heating cost of electroplating liquid and parts cleaning liquid in electroplating plants now accounts for 20% to 30% of the total electricity cost of electroplating plants. Many electroplating plants use traditional coal boilers and oil boilers to produce hot water, which consumes a lot of energy and has high cost. The air source heat pump uses a high-temperature heat pump technology system, which is simple and stable to operate, reduces about 50% of the operating cost, and ensures the normal operation of the production process. Compared with traditional electric boilers with high-temperature hot water, it can save 50% of electricity consumption and reduce the trouble of frequent replacement of electric heating pipes. At the same time, the unit does not discharge any pollutants, which is safer and more environmentally friendly.
2. Energy-saving application for home heating
Traditional coal-fired small boilers have always been the main heating equipment for winter heating for northern residents. After being eliminated, better energy-saving and environmentally friendly products are needed to replace them. In view of the low temperature weather in the north, the air source heat pump developed with innovative technology can also work normally in a low temperature environment of minus 25℃. Ultra-low temperature air source heat pumps are mainly used in cold weather in the north. When the temperature drops to a certain level, the air source heat pump will not frost when running, and it can still operate as usual to supply hot water; it effectively overcomes the difficulty of frosting when the heat pump is running at low temperature. The air source heat pump adopts a high-efficiency scroll compressor and cooperates with high-efficiency casing heat exchange. It is not only low in noise and small in size, but also has a stable heat source and is green and environmentally friendly. It can provide floor heating in winter and air conditioning in summer.
3. High-temperature drying energy-saving application
In recent years, my country's drying technology has developed rapidly. From traditional drying technology to the current air source heat pump high-temperature drying, it is widely used in industrial production and agricultural and sideline product processing. Compared with existing drying equipment, air source heat pump high-temperature dryer has low consumption, and its operating cost is about 1/4 of general electric heating and about 1/3 of fuel cost. In the food processing industry, in addition to achieving energy saving and consumption reduction, the most important thing for air source heat pump high-temperature drying is to ensure stable material quality, good color and high product grade. At present, the air source heat pump high temperature drying unit can produce a 30℃-80℃ adjustable temperature environment, and can automatically adjust the speed of the heat dissipation fan, which can basically meet the drying process requirements of most agricultural products and industrial products. For example, for fruit and vegetable drying, traditional equipment takes at least 24 hours to process 1 ton of vegetables, while the air source heat pump high temperature drying unit only takes 4 to 8 hours to complete. In fact, for production companies, the air source heat pump high temperature drying unit not only reduces 70% of operating costs, but also does not require special personnel on duty, greatly saving labor costs.
