Why Does DC Inverter Air Source Heat Pump Becomes Popular?

Views: 550     Author: Site Editor     Publish Time: 2020-04-30      Origin: Site

Air source heat pump (also called ASHP), is a new type of hot water and house heating pump, popular among people all over the world because of its safety, high efficiency, energy saving and convenience. Of all the different categories of ASHP, DC inverter heat pump has become the most popular type.


The prevalence of DC inverter air source heat pumps is also due to the market demand. No matter which region, the climate and ambient temperature will change at any time within 365 days of a year. Under different temperatures, people's demand for hot water and house heating will naturally be different. Non-inverter heat pump is also commonly known as the "ordinary" on/off heat pump. The compressor of this type of heat pump cannot adjust the frequency, but only operates at a single frequency, which is not flexible enough. DC inverter air source heat pumps can change the frequency of the compressor because of the addition of a frequency inverter in the equipment to transform the compressor. It is more adaptable to the complex environment.

Take cold areas for example, house heating at -10 ambient temperature may require 50 hot water, so the heat pump compressor will need to run at full load, and if the temperature is only 0, the heating may only need 35 hot water. According to the data, in some places, the cold weather with ambient temperature lower than -10 lasts for less than 10% of days in a year. That is to say, most of the time, ASHP does not need to be fully operated. On/off heat pump units are unable to change the operating frequency of their compressors, so they cost more electricity.


If choosing a DC inverter air to water heat pump, we can solve this problem completely. There are two built-in modes inside the heat pump unit: the energy-saving mode and the fast heating mode. Under the energy-saving mode, the compressor operates at a lower frequency, which can achieve the maximum power-saving effect. Under the fast heating mode, the heat pump runs at a high frequency, and hot water production can be fulfilled in a short time.


About SPRSUN DC Inverter Heat Pumps

Tested by TÜV SÜD, SPRSUN DC inverter air source heat pumps have been rated ERP A+++ Level, meaning that they are highly energy-efficient. The ERP energy label gives an indication of energy efficiency in products. With a maximum heating capacity from 9.5KW to 18.6KW, the new heat pumps from SPRSUN have been rated A+++, which is the highest rating available. This rating indicates that our air source heat pumps have low energy consumption and a high COP.


Working at as low as -20℃, SPRSUN Monoblock DC Inverter Air Source Heat Pumps can be used to provide house heating and cooling, as well as hot water in domestic settings. The highly energy-efficient heat pumps use more than 30% less energy than other air source heat pumps, with a maximum COP of 5.65.


The Panasonic rotary compressor enables the heat pump units to operate at high frequency and heat water at a faster speed, greatly reducing the energy consumption. With the DC inverter brushless fans, SPRSUN DC inverter heat pumps are able to control the sound at a satisfactory level. They operate in a wide voltage range: 150V-260V (1ph) or 330V-450V (3ph), which reduces the impact of voltage instability on the environment. The intelligent CAREL controller with RS485 WIFI APP is adopted to realize the linkage control between the heat pump unit and the terminal application end. With the Cascade function, multiple units can be controlled with one panel. Moreover, the smart defrosting technology enables the unit to make optimal defrosting decisions to minimize energy consumption and improve customer satisfaction.


SPRSUN products also come with a 24-month warranty from the delivery date of purchased products. Free assembly parts are provided if a product fails while being used in a normal manner. Lifelong maintenance services are also available after the end of the warranty, with only low fees to complete repairs and servicing.
