It is important to establish that there are different types of heat pumps. Ground source heat pumps (GSHPs) have a considerable proportion of their installation below ground, which normally makes their noise impact minimal. Air source heat pumps (ASHPs) contain a fan, which is often the main...

Samsung has launched the company’s mostadvanced air source heat pump to date, representing an evolution in low carbon heating solutions. TheEHS Mono HT Quietis a next generation high temperature, low noise heat pump, ideal at a time when many consumers, self-builders and developers are looking...
The fan, which will be available in the 450 and 500 sizes typical for heat pumps in single- or two-family homes, has also been fitted with an air inlet grille. This FlowGrid, which acts as a rectifier for air flow, drastically reduces noise-generating distur...
It functions just like a central AC when it absorbs heat and releases it outside. But it also works in reverse order, as it collects heat from the outside air and releases it inside the house. Air-source heat pumps can now be used in colder climates, due to advancements in the ...
The highly energy-efficient DC inverter heat pumps use more than 30% less energy than other air source heat pumps. Before the indoor temperature reaches the set value, the Panasonic rotary compressor delivers high levels of efficiency, enabling the unit to operate at high frequency so that it...
If there is good air flow out of supply registers but in cooling mode the air does not get cool, or in heating mode (for heat pumps) the air delivered does not get warm the trouble could be that the outdoor compressor unit is not working or that the system has lost its refrigerant ...
Noise Attenuation in Rotary Heat Exchanges Sound attenuation vs. frequency in rotating heat exchangers. Signals - Adding Decibels The logarithmic decibel scale is convenient when adding signal values like sound power, pressure and others from two or more sources. Velocity Classification of Ventilation...
