Agricultural New Energy - Heat Pump
Heat pump technology:
A heat pump is a device that can take low-grade heat from natural air, water, or soil, output power that can be used to produce high-grade thermal energy, and can convert the consumed power into heat energy that is 3 times or more than 3 times. Efficient energy supply technology. The application of heat pump technology in the air conditioning field can be divided into three types: air source heat pump, water source heat pump and ground source heat pump. Since the heat pump extracts energy from the natural world, it is highly efficient and does not emit any pollutants. It is the cleanest, most economical way of energy today. In today's increasingly scarce resources, as the most advanced way for humans to use low-temperature heat energy, heat pump technology has received extensive attention and attention worldwide.

Air source heat pump:
The air source heat pump uses the infinite energy contained in the air. In the summer, the indoor heat flows to the higher temperature and the room is cool. In the winter, the heat in the outdoor air can be used to heat the room. Because the real cooling and heating of this central air conditioner comes from the outdoor air, it does not need a cooling water system during the summer cooling, so it is very economical to operate and can save a lot of water resources. At the same time, the system does not generate any pollutants during its operation. It is in line with China's energy conservation and environmental protection trends and policies.
However, for a long time, the central air-source heat pump central air-conditioning can only be used in the middle and lower reaches of the Yangtze River, southwest and south China, but it cannot work normally in the northern regions in the winter. In 1996, Tsinghua Tongfang made technical improvements to the first-generation air source heat pump. The unit's unique "overcooling and suppressing ice" technology effectively solved the problem of incomplete defrosting, making it the lowest temperature in the winter - 8 °C in the Yangtze River Basin and the Yellow River. The basin area was successfully used.
After five years of painstaking research, Tsinghua Tongfang maximized the potential of the heat pump system and launched the only low-temperature air source heat pump unit that achieves -22°C heating in the world. The breakthrough of the air source heat pump was applied to North China for the first time, completely changing the long-term northern region. The history of using coal and gas heating has played a positive role in improving the environment and saving energy.
Mushrooms are one of the familiar "mountain treasures". To obtain this reputation, mushrooms are not only dependent on taste, but also related to their rich nutrition and excellent health care value. Mushrooms are very rich in minerals, and especially worth mentioning is potassium. Potassium prevents strokes, assists normal muscle contraction, and reduces hypertension. What we usually call a "potassium star" banana, the potassium content is 256 mg / 100 g, and the potassium content of common mushrooms are: Tricholoma (white mushroom) 1655 mg / 100 g, mushroom 312 mg / 100 g, Agaricus 307 mg / 100 g, far more than bananas.
