District Heating

• Heat Pumps for District Heating For Countries with a Cold climate
• 2-STAGE HEAT PUMP With C.O.P. of up to 6.4

The Process:
VIM technology can be used to supply hot water for buildings and for District Heating, using a natural body of water (for example: sea, lake, or river) as the heat source.
In these heating applications, the water vapor’s condensation heat, at around 10°C (50°F), is further increased by a standard heat pump (a conventional chiller), thus heating water to the desired temperature ranging from 40°C to 70°C (104°F to 158°F).

This heat pump, where driven by a gas turbine (GT), achieves very high fuel utilization ratios - up to 220%. With such high efficiency, the VIM uses less than half of the natural gas required by gas-fired boilers in producing the same heating capacity.
For these heating applications, the ice slurry is generated in the VIM freezer and discharged back to the water source.

A well-proven technology
VIM had long been used for District Heating by the town of Augustenborg, Denmark.

Very high energy efficiency
GT-driven installations provide fuel utilization rates up to 220%.

Low operation & maintenance costs

An optimal solution, when near large cold water sources
VIM utilizes the heat within any cold water source near 0°C (32°F) to efficiently produce hot water, during all ambient air temperatures.

Environmentally friendly
VIM employs water as its primary refrigerant.
