Geothermal pumps reduce waste

At present, the total direct use of the country has reached 2410 MW, ranking first in the world, but the level of utilization and efficiency is relatively low, and the energy utilization rate for the temperature range of 25°C to 50°C is poor. In order to achieve the sustainable development goals, we will vigorously develop technology for the use of renewable energy in new energy sources in Hangzhou, which mentions the development of geothermal heat pump technology to make full use of geothermal resources.

Not all geothermal wells can be fully utilized. Some geothermal fields are low-temperature geothermal fields. The geothermal water temperature is lower than 55°C, and the energy grade is low. It cannot be directly used as a hot water heating cycle for radiators. System heating.

And the tail water after the geothermal water heating is also a problem, the water temperature after geothermal heating is relatively high, generally above 40 °C, causing a waste of resources. It also causes thermal pollution and does not meet the requirements of environmental protection.

Under such circumstances, Chinese scientists developed a domestic high-temperature water source heat pump unit with unique domestic technology and adopted the high-temperature environmentally friendly working medium HTR01, 02, which broke through the temperature bottleneck of the electric compression heat pump, and the high water supply temperature reached 95°C. The low-grade hot water at 15~60°C recovers heat and produces high-temperature hot water at 60~95°C. It is a high-tech product with the advantages of “high temperature, high efficiency, environmental protection, and energy saving”. Fundamentally solve the status of such waste heat resources can not be directly recycled by the heat pump unit.
