The pragmatic definition of the COP is: COP = (What you Get)/(What you Pay For). This measure of performance can have a value greater than unity, and it is this fact that makes a heat pump an ...

A German research group has proposed to use reinforcement learning (RL) to optimize the utilization of heat pumps (HPs) for space heating in big apartment complexes. RL is a type of machine ...

Lennox Residential HVAC has launched an extreme cold climate heat pump that warms a house with low global warming potential (GWP) refrigerant in temperatures as low as -20F. It’s called the ...

They coupled it with either a heat storage tank or a shallow borehole heat exchanger and found that both system typologies increase the heat pump’s coefficient of performance. Researchers from ...
