SPRSUN R290 DC Inverter Air Source Heat Pumps
The SPRSUN R290 DC Inverter Air-to-Water Heat Pump is designed with Panasonic DC Inverter Compressor and DC Inverter Fan Motor to meet stringent requirements for eco-friendliness, efficiency, stability, and quietness. In addition to utilizing R290 green gas and inverter technology, the new unit is also rated with an A+++ energy label, reducing energy bills for residential uses. As an ideal choice of multiple functions (heating, cooling and/or hot water), the R290 heat pump has the following significant features compared with the R410/R32 series.

1. Lower GWP with Eco-friendly refrigerant R290

The new SPRSUN DC Inverter Air Source Heat Pumps specially adopt R290 refrigerant with global warming potential (GWP) as low as 3.3. Compared with R290, R410A refrigerant actually has a high GWP value and high greenhouse gas effect. As an environment-friendly refrigerant, R290 has many advantages, making it very suitable for the application of low-temperature heat pump heating in the cold areas.
2.  Better Energy Consumption Monitoring with Power Data Module
This is a useful tool for households to efficiently monitor the energy savings of the DC inver ter heat pump at real time. The power data module of the new R290 heat pump unit displays the current input power, able to display monthly power consumption/total power consumption.

3.  Reduced Electrical Energy with Smart Grid Ready Heat Pump
The integration of a "SG-Ready" (Smart-Grid-Ready) heat pump is an advanced form of sector coupling of electricity and heat - often also called "Power-to-Heat" application. The control ensures that the heat pump slightly overheats the thermal storage at times when PV surplus electricity is available, in order to then save electrical energy at times when there is no cheap surplus electricity.

4.  Max. Outlet Water Temperature Reaches 75 ˚ C
By combining eco-friendly R290 natural refrigerant and inverter heating technology, the new heat pump is able to operate from -25°C to 45℃, maintaining high COP and reliable stability. More importantly, its max. outlet water temperature reaches 75℃ without electric heating.

5.  Better User Friendliness with Additional Features
1. Intelligent humanized controller, which collect opinions to optimize the operation interface
2.The controller has a built-in linkage switch interface, which can be seamlessly connected to the temperature controller;
3.The unit has built-in solar auxiliary heating, which can be seamlessly connected with solar auxiliary heating;
4.The main interface can quickly switch the fan mode (normal, economic, night, silent);
5.The panel structure is revised to support 86 box installation; The 485-communication port of the panel supports communication with the temperature controller.
