What are the advantages of DC variable frequency heat pump?
DC variable frequency heat pump is a development trend and trend in recent years. DC variable frequency heat pumps are well known for their changes in operating frequency, so what are the advantages of DC variable frequency heat pumps? DC variable frequency heat pump uses soft start, so the starting current is low. It can work to -25℃, providing us with comfortable and constant water temperature. It has the characteristics of high efficiency, energy saving, precise temperature control, environmental protection and low noise.
1. Soft start, low starting current
With soft start function, the heat pump can start smoothly, thereby reducing the starting current and avoiding tripping due to overcurrent. In addition, since there is no current affecting the compressor, the service life of the DC variable frequency heat pump unit is extended.
2. Comfortable and constant water temperature
The operating frequency of the variable frequency heat pump compressor is automatically adjusted according to changes in ambient temperature and water temperature. When the ambient temperature is low, the compressor runs at a high frequency and reaches the target water temperature quickly. When the ambient temperature is high, the compressor reduces the operating frequency and runs at a low frequency to keep the water temperature stable. Therefore, the room temperature or hot water temperature is always comfortable and constant.
3. High efficiency, can work below -25℃
Since the DC variable frequency heat pump has variable operating frequency under different ambient temperatures, it is more suitable to work in low-temperature environments, with operating temperatures as low as -25°C, while ensuring efficient heating at low temperatures.
4. Low noise
The heat pump unit does not start and stop frequently, which not only makes less noise, but also saves energy. In addition, when the DC variable frequency heat pump operates at low frequency, the noise is relatively low, providing us with a quieter and more comfortable environment.
5. Energy saving and environmental protection
Like other types of heat pumps, DC variable frequency heat pumps are a low-carbon and energy-saving product. It does not produce any waste gas, waste water and waste residue emissions. The operating cost of a DC variable frequency heat pump is only 1/4 of an electric water heater, 1/3 of an oil and gas water heater, and 1/2 of a solar water heater. Therefore, installing a DC variable frequency heat pump is an effective way to reduce our energy costs.
