WATER SOURCE HEAT PUMPS
What is a water loop system with water source heat pumps?
The water loop system enables distributed cooling and heating
production at different temperatures with a single water circuit.
The recovery of condensation heat units in cooling can used for units in heating
and vice-versa, thus providing a balanced and highly efficient system.
These indoor units are called water source heat pumps which are
equipped with a compressor and 2 heat exchangers to allow
energy transfer between the water loop and air within
the space.

Key features for ECOi-LOOP.
· High-efficiency
· Heating and cooling of rooms at the same time. All
units are connected to the same water loop
· Decentralised cool/heat production (closed water
circuit)
· Water heater or cooling tower do not need to be
operated as long as cooling and heating loads are
roughly balanced. Temperature in the water loop
will be kept between 16 and 32 °C
· Reduced refrigerant charge (no refrigerant pipes to
an outdoor unit required)
· Low risk of leakage (hermetically sealed systems)
· Water source heat pumps can be easily added or
removed without changing the system layout
· Each unit is autonomous and has its own controller
allowing also its own safety
