pumps are systems that transfer heat energy from a lower
temperature to a higher temperature (hot source), by inverting
the natural thermal flow (in which heat is carried from warm
mediums towards cooler ones). This flow capability works
whether one wishes to provide heating or cooling with a single
piece of equipment.
heating mode, the system supplies the room heat “pumped”
from the outside and the heat energy to fuel the heat pump
itself, thereby obtaining high energy efficiency. The natural
gas absorption heat pump differs from traditional electrical
heat pumps due to the energy that it uses. Instead of
consuming electric energy to operate a vapor compression
cycle, the absorption heat pump consumes gas in a premixing
burner, which heats a solution of water and ammonia in a
completely sealed absorption circuit.
generic terms, absorption heat pumps are hydronic type
systems, as they heat and/or cool the water that is required.
One of the many advantages of this characteristic is that it
allows the heating and cooling input temperature to be managed
better, making for precise adjustments to indoor comfort, thus
increasing the operating efficiency of the entire system.
