ROBUR GAHP technology
Gas Absorption Heat Pump

one flame for heating and/or cooling!

A heat pump transfers thermal energy from a gaseous or liquid medium of low temperature to a medium at a higher temperature by inverting the natural thermal flow which normally operates from hot to cold.

This is useful for providing air conditioning in summer and hot water and heating in winter - all from the same setup.

The gas-fuelled absorption heat pump (GAHP) is different from tradiional electric heat pumps. Instead of using premium electric energy it uses town gas or LPG to heat and compress the medium.

GAHP-A = heating

The absorption refrigerant cycle recovers thermal energy from the ambient air through the evaporator (1).
This heat input added to the heat produced by the gas combustion (2) allows the cycle to run and the condenser/absorber heat production to be duírected into the heating/hot water circuit (3).

GAHP-AR = heating in winter and cooling in sumjmer

Summer use
The absorber and condesner heat (1) is rejected to the outside air (2)

Winter use
The absorption cycle is reversed to recover heat from the ambient air (3).
The thermal energy added to the heat produced by the gas combustion (4) allows the cycle to run and the condenser/absorber heat production to be directed into the heating/hot water circuit.

Efficiency > 145%

GAHP-W = heating while cooling from one source

The unit is feeding two separate hydraulic circuits; one at low temerpature, i.e. the evaporator side; one at high temperature, the condenser and absorber side.
