High-Efficiency Water Source Heat Pump Ground Source Heating &
Cooling System
Water (Ground) Source Heat Pump Unit
A water-source heat pump is an integrated heat pump unit that uses
water as a heat source for both cooling and heating. During heating
operation, it uses water as a heat source, and during cooling
operation, it uses water as a heat sink. Water-source heat pump
systems vary in operating conditions depending on the source of the
heat source. They are generally classified as follows:
wastewater-source heat pump systems, surface water-source heat pump
systems, and ground-source heat pump systems. Among these,
ground-source heat pump systems can be further divided into
groundwater-source heat pump systems and soil-coupled heat pump
systems. Currently, ground-source heat pump systems are the most
widely applied.
Soil-coupled heat pump systems are heat pump systems that use soil
as a heat source or sink, also known as ground-source heat pump
systems with underground pipes. In this system, pipes are buried
underground to serve as heat exchangers, connected to the heat pump
unit to form a closed-loop circuit. The circulation of fluid within
the pipes enables the system to operate continuously. In
groundwater-source heat pump systems, the low-temperature heat
source is groundwater extracted from wells or abandoned mines.
Geothermal heat pump systems utilize geothermal energy, making them
unaffected by outdoor environmental conditions and climate. The
heat source temperature remains relatively stable throughout the
year, typically ranging from 10°C to 25°C. Compared to traditional
heating and cooling systems, geothermal heat pump systems offer
higher cooling and heating coefficients and more stable unit
operation. Additionally, the system does not require cooling towers
or boilers, eliminating outdoor noise and exhaust emissions, making
it a more environmentally friendly solution.

lubrication, reducing failure rates.
The latest generation of compressor and impeller design reduces
vibration and noise, ensuring smooth operation and excellent
adaptability to load variations.
Over 20 years of experience in screw chiller design, production,
and operation provide solid assurance and peace of mind.
Low-Carbon & Eco-Friendly
The unit minimizes both indirect and direct carbon emissions,
lowering the carbon footprint and promoting sustainable
development.
High-efficiency operation reduces the need for power supply,
indirectly lowering electricity-related carbon emissions.
Proprietary hybrid falling-film evaporator design reduces
refrigerant charge and leakage, minimizing the impact on greenhouse
gas emissions.
