Heat pump technology
NUOS range uses a thermodynamic cycle to heat the water inside the storage tank through the air sucked by the thermal group inverting the heat natural flow. A refrigerant fluid (R134A), through status changes, compression and expansion cycles, withdraws the heat in the air at low temperature and gives it to domestic water at a higher temperature. This is the reverse mechanism to the one used in refrigerators. The product electric consumption is only the one necessary to let the fan (that captures the air) and the compressor (that allows the refrigerant fluid to circulate in the system) work.
NUOS heat pump:
more than just a water heater
WORKING PRINCIPLE
The heat pump is a device which is used to transfer heat from the heat source at lower temperature to the heat source at higher temperature; this process is not spontaneous but requires a “pumping work” from the machine itself. An heat pump works like an hydraulic pump which, thanks to a certain amount of mechanical energy, moves the water from a lower level to an upper level, disregarding the normal laws of nature.
THERMODYNAMICAL HEAT PUMPS
There are many physical principle thanks to which it is possible to perform the “pumping” of the heat: gas compression, Peltier’s thermoelectric effect and the refrigeration cycle with phase change. In the case of an heat pump with phase change, a uid evaporates and condensates at different temperature in a thermodynamical cycle, thanks to expansion and compression processes. When evaporating, the uid subtracts heat from the source at lower temperature while when condensating the uid gives back the heat to the source at higher temperature. The most important part of this machine is therefore a compressor driven by an electric motor.
