Low noise air source Heat Pump is different from traditional electric heating and gas heating because the air source heat pump can use low-grade energy to produce high-grade energy, making it more efficient, energy-saving, environmentally friendly and safe. Its main components include indoor unit, outdoor unit, control system, etc.
The core technology of the low-noise air source heat pump is the use of inverter technology, which not only enables precise control of indoor temperature, but also greatly reduces the noise level, improves efficiency, saves energy, and thus reduces operating costs. It operates by absorbing heat from the air through the outdoor unit, transporting it to the indoor unit through pipes, and then releasing the heat into the indoor air to achieve heating or cooling of the indoor air. Its characteristic is that it is not affected by the change of outdoor temperature and can work normally in a low temperature environment of -25°C. It has the advantages of high reliability, energy saving and long life. Meanwhile, since it does not need to burn any substance, it does not produce any waste gas and pollutants, which is a very environmentally friendly way of heating.
