1. During winter heating, it can replace the boiler system, as there is no combustion process, avoiding exhaust pollution; Summer cooling eliminates the need for cooling towers and does not cause urban heat island effects, making the environment cleaner and more beautiful.
2. The geothermal water source heat pump central air conditioning system utilizes low-grade energy resources such as lake water, river water, groundwater, and geothermal tailwater. With the help of a compressor system, it consumes some electrical energy and extracts it during winter to supply indoor air; In summer, indoor heat energy is extracted and released into the surface layer to achieve the purpose of air conditioning.
3. A technology that utilizes low-grade thermal energy resources formed by absorbing solar and geothermal energy from shallow water sources on the Earth's surface, such as groundwater, rivers, and lakes, and uses the principle of heat pumps to transfer low-grade thermal energy to high-grade thermal energy through a small amount of high-level electrical energy input.
4. The available water temperature in winter is 12-22 ℃, which is higher than the outdoor air temperature in winter. Therefore, the evaporation temperature of the heat pump cycle is increased, and the energy efficiency ratio is also improved. A well-designed water source heat pump unit can reduce electricity consumption compared to electric heating.
