In a straight heat pump or supplementary electric heater application, at least one outdoor thermostat is required to cycle the heaters as the outdoor temperature…
During a defrost cycle, the heat pump switches from heating to cooling. To prevent cool air from being circulated when heating is needed, the control…
On mild temperature heating days, the heat pump handles all heating needs. When the outdoor temperature reaches the “balance point” of the home (heat loss…
Solar energy, as either direct or diffuse radiation, is similar to air in its characteristics. A solar-source heat pump or a combined solar/heat pump heating…
Soil or sub-soil (ground source) systems are used for residential and commercial applications and have similar advantages to water-source systems, due to the relatively high…
Water-source units are common in applied or built-up installations where internal heat sources or heat or cold reclamation is possible. In addition, solar or off-peak…
While ambient air is free and widely available, there are a number of problems associated with its use as a heat source. In the cooler…
The most common waste heat streams in industry are cooling water, effluent, condensate, moisture, and condenser heat from refrigeration plants. Because of the fluctuation in…
As mentioned earlier, a heat pump is a device that gets heat at a certain temperature and releases this heat at a higher temperature. When…
