A heat pump is a device that can obtain low-grade heat from natural air, water or soil, use electricity to do work, and output usable high-grade heat energy. It can triple or even triple the power consumption. It is a high-efficiency energy supply technology that can produce more than three times the thermal energy. The application of heat pump technology in the field of air conditioning can be divided into three categories: air source heat pumps, water source heat pumps and ground source heat pumps. Because heat pumps extract energy from nature, they are highly efficient and do not emit any pollutants. They are the cleanest and most economical energy method today. Today, with increasingly scarce resources, heat pump technology, as the most advanced way for humans to utilize low-temperature thermal energy, has received widespread attention and importance around the world.
Tsinghua Tongfang is the first domestic enterprise to apply heat pump technology to the field of air conditioning. With its mature technology research and development capabilities in this field, it has developed air source heat pumps, water source heat pumps, ground source heat pumps, heat pump water heaters, etc. It has four major series of heat pump products, deepens the technology and types of products according to different regional climate conditions and resource conditions, and has obtained more than 100 patented technologies. Tsinghua Tongfang has become a leader in the field of heat pump central air conditioning. Air source heat pumps use the infinite energy contained in the air to flow indoor heat to the higher-temperature outdoors in summer to keep the room cooler; in winter, the heat in the outdoor air can be used for heating to keep the room warm. Since the real cooling and heating heat of this kind of central air conditioner comes from the outdoor air, it does not require a cooling water system during cooling in summer, so the operating cost is very economical, and it can also save a lot of water resources. At the same time, no pollutants are produced when the system is working. It is very in line with my country's energy conservation and environmental protection trends and policies.
However, for a long time, ordinary air source heat pump central air conditioners can only be used in the middle and lower reaches of the Yangtze River, southwest and southern China, and cannot work normally in the northern region in winter. In 1996, Tsinghua Tongfang made technical improvements to the first-generation air source heat pump. The unit's unique "supercooling and ice suppression" technology effectively solved the problem of incomplete defrosting, allowing it to operate in the Yangtze River Basin and Yellow River where the lowest temperature in winter is -8°C. Used successfully in watershed areas.
After five years of painstaking research, Tsinghua Tongfang maximized the potential of the heat pump system and once again launched the world's only low-temperature air source heat pump unit that can achieve -22°C heating. The air source heat pump broke through the restrictions and was applied to North China for the first time. , completely changed the long history of using coal and gas for heating in the northern region, and played a positive role in improving the environment and saving energy.
