PHNIX Self-developed Driver Board

Full Inverter Technology

Unlike a traditional heat pump with a single-speed compressor which by switching on and off periodically to adjust the performance of the heating & cooling, a full inverter heat pump uses a variable-speed compressor that can automatically adjust the output needed at the lowest consumption of power and maintain the best temperature at different climatic conditions. When the heating demand is high, the inverter compressor and the fan motor will start running at a high speed, inversely, they will run at a low speed.

Summer Season

i-GreenLine R290 full-inverter pool heat pump adopts self-developed driver boards, the unit is highlighted with a central control system as an RS485 port and Modbus protocol is designed for communications in every unit. Furthermore, all machines have PV-Ready function. Ultra R290 pool heat pump can connect with Photovoltaic (PV) system and directly use the electricity generated during operation. It can achieve 100% free running when solar energy is the strongest in summer.

Four Season Running

Autumn Season

With the help of anti-noise technology of fan motor and compressor, the unit can run smoothly and super quietly even if it works at full capacity. The sound pressure is kept to as low as 34- 43.5 dB(A) at 1-meter distance, providing an entirely quiet and relaxing swimming environment. Moreover, R290 pool heat pump can maintain the highest COP of 11 during 50%-load operation, reflecting an obvious advantage in energy conservation and high efficiency.

Four Season Running

Winter Season

Merging the advanced full inverter technology with green R290 refrigerant, R290 pool heat pumps can ensure optimal performance from -25鈩 to 43鈩, which can run safely and reliably all year round. More significantly, the unit can operate efficiently at -25掳C, maintaining high

COP, reliable stabilityand strong heating capacity for an indoor pool. In addition, the maximum outlet temperature is 45鈩 for SPA.

With the application of the most cutting-edgy technology and modern design, the R290 inverter pool heat pump undoubtedly meet stringent requirements for efficiency, stability and quietness. Both the R290 eco-friendly refrigerant and the inverter technology has contributed to i-GreenLine Ultra range awarded the A++ label. The top energy rating A++ means that the unit is energy-efficient and can greatly reduce energy cost for users.


Production and Manufacturing Requirements for R290 Refrigerant

1 Production Processes锛圧efrigerant Charging锛

* Employees must pass the qualification assessment for key positions and work with the certificates.

* Check the effectiveness of refrigerant charging equipment and ventilation facilities at a fixed time every day.

* Set up static elimination facilities to discharge static electricity from the human body before entering the work area.

* Before charging R290 refrigerant, make sure that the ventilation and exhaust system and combustible gas detector in the charging area are turned on, and that each air outlet is ventilated smoothly.

* An obvious danger source identification line must be drawn within a radius of 3m around the charging machine placement area and the refrigerant charging area. It is forbidden to use open flames, pyrotechnics and high-temperature items (such as hot-melt welding guns, etc.) within this range, and it is not allowed to use a grinder for grinding.

2 Laboratory Testing

Based on the flammability characteristics of R290 gas, PHNIX built up several anti-explosion labs to ensure safer and higher-quality R290 heat pumps. The lab is specially designed with multiple complicated devices, including explosion-proof fans, circuits and other specific anti -explosion equipments, ventilation device, R290 concentration detection probes and automatic alarm systems. In addition, preventing static electricity is one of the important measures to ensure safety. Static electricity removal devices are installed and anti-static rubber is laid in the laboratory and

production lines, where employees need to eliminate static electricity before entering. In particular, experimenters should wear anti-static clothing and shoes.

Protective Measures for R290


* Warehouses must be ventilated

* R290 leak alarm system must be installed

* Fire and explosion hazard signs must be affixed

* Appropriate fire extinguishers must be equipped


*Fire extinguishers are required for transport equipment

*Avoid sparks, smoking and other sources of ignition

*Vertical transport to prevent dumping and collision


* Professional staff is required for installation

* Must be installed outdoors

* Keep away from fire


* Must have professional staff to carry out

* After-sales maintenance

Protective Measures for R290

R290 Refrigerant

R290 refrigerant has an extremely low GWP value (GWP=3), showing a minimal impact on the global-warming effect and playing a positive role in going carbon-neutral.

The Feature of R290 Refrigerant

*  Stable running at -25鈩 ambient temperature.

* The max outlet water temperature can be up to 75鈩.

* Stable operation: R290 operates stably at low ambient temperature, and can reach the same level of R32 EVI product at ultra-low temperature.

* Strong cooling capacity: The cooling capacity of R290 is better than that of R32, which is 103%-105% of the cooling capacity of the same R32 product.

* Small refrigerant charge: For heat pump with the same capacity, the refrigerant charge of R290 is 20% less than that of R32 refrigerant and 30% less than that of R410A refrigerant.
