General

Information about the installation

Product information

Hydrolution is a complete modern heat pump system that

offers effective technical energy saving and reduced carbon

dioxide emissions. Heat production is safe and economical

with integrated hot water heater, immersion heater, circulation

pump and climate system in the indoor unit.

The heat is retrieved from the outdoor air through outdoor unit,

where the refrigerant circulated in a closed piping system transfers

the heat from the heat source (outdoor air) to indoor unit.

This eliminates the need for holes and coils in the ground.

Features of Hydrolution

■ Optimal annual heating factor thanks to the inverter

controlled compressor.

■ Outdoor unit with compact dimensions.

■ Speed controlled system pump that supplies the heat pump

with suitable system ow.

■ Optimized operating costs. The speed of the compressor is

adjusted according to the demand.

■ Integrated coil water heater in indoor unit.

■ Integrated clock for scheduling extra hot water and

temperature lowering/increasing the supply water temperature.

■ Prepared for control of two heating systems.

■ Integrated active cooling function.

■ Possible to connect external heat sources.

Principle of operation Hydrolution

Function

Hydrolution is a system that can produce heating, hot water

and cooling.

The principle during heating can be simplied as follows:

1. The refrigerant in outdoor unit takes the heat from the

outdoor air and is compressed to higher temperature by the

compressor.

2. The hot refrigerant (now in gas state) is routed into indoor unit.

3. The refrigerant releases the heat for further distribution in

the system.

4. The refrigerant (now in liquid state) is routed back to

outdoor unit and the process is repeated.

By reversing the entire process, and thereby the refrigerant in

outdoor unit takes the heat from the water and release the heat

to the outdoor air, the heat pump can cool instead if necessary.

Indoor unit determines when outdoor unit is to work and not to

work, using the collated data from the temperature sensor. In

the event of extra heat demands, indoor unit can connect additional

heat source in the form of the internal immersion heater, or any

connected external heat source.
