Micro-District Concept, an Emerging Trend in Heat Pump in United States
Heat pumps are energy efficient devices that transfer heat from a location with little air circulation to the warmer regions of a building. They are usually installed as part of a complete HVAC system, but may also be used independently. They can provide a comfortable climate for living, while at the same time lowering your monthly utility bill.

As the heat pump extracts energy, it uses the stored energy to...
