Of course, the performance of a water-source heat pump is closely tied to the selection of the water-cooling agent. In principle, any water source that meets the heating or cooling requirements of the user—both in terms of temperature and water quality, and that does not cause corrosion or damage to the system equipment—can be used as a water source for a heat pump. This can include either recycled water or naturally occurring water sources. However, due to the increasing severity of environmental pollution and unpredictable conditions, careful consideration must still be given when selecting a water source.
Generally, there are two main types of water sources commonly used for water-source heat pumps:
1. **Recycled Water Sources**: These include treated municipal wastewater, industrial effluent, mine drainage, oil field wastewater, and thermal power plant cooling water. For users who can conditionally use such water, it offers an opportunity to turn waste into value, reduce initial investment, and conserve water resources. If properly utilized, this type of water can significantly contribute to both energy efficiency and environmental protection.
2. **Natural Water Sources**: These include atmospheric water, surface water (such as rivers, lakes, reservoirs, and ponds), and groundwater. Surface water accounts for about 96.5% of the Earth's total natural water reserves. Coastal cities may consider using seawater as a heat pump source, as seen in some foreign applications. In China, several coastal areas have long used seawater for industrial cooling. Recently, research has been conducted on using seawater for heat pump systems, but practical implementation is still in development.
Surface water typically has lower salinity than seawater but contains more organic matter, suspended solids, colloids, algae, and sediment, which require treatment before being used in a heat pump system. Groundwater, on the other hand, is found beneath the Earth’s surface in aquifers. It is widely available, has better water quality than surface water, and maintains a more stable temperature, making it a more ideal choice for central air conditioning systems.
