Routinely cleaning your heat pump coil can keep it running efficiently and ensure it lasts longer. Here's how to do it ...

We measure air conditioning units in tons, with 1 ton representing 12,000 BTUs (a unit of heat). In general, the larger the AC unit, the larger (and more expensive) the evaporator coil cost.

Groundwater and deep lake water can potentially serve as a vast network of seasonal chilled thermal storage reservoirs. These reservoirs have been used as heat sinks and sources for water-to-air heat ...

“The target temperature of the network is the temperature of the heat pump evaporator, and the target temperature of the heat pump is the process temperature,” they explained, noting that the ...
