Polestar E-series commercial heat pump water heater can operate at -26℃ low ambient temperature and can have 55℃ outlet water temperature.
Polestar heat pumps can realize graded startup, reduce the startup current of the unit and reduce the impact on the power grid.
Through a detection and AI-learning function, the compressor and the unit with the best performance are searched and identified during each startup, so as to reduce the system wear and prolong the service life cycle of the heat pumps and to ensure the best performance and reliability of the unit.
Polestar E series commercial heat pump systems can realize 25%~50%~75%~100% four-stage regulation in a single unit, and 16 modular combinations can realize 1.5%-100% stepless regulation, which can realize accurate output in partial load and reduce system energy consumption.
The hermetic scroll compressor of an internationally famous brand, scroll axial and radial flexible technology, reliable and efficient.
Equipped with a check valve so the safety co-efficient is higher, ultra-large capacity, super liquid impact resistance, and long service life.
Integrated axial flow aluminum alloy low noise fan with large air volume perfectly realizes aerodynamic performance.
The unique tooth edge of the wing is designed with blades to effectively control air turbulence, reduce cyclone and wind noise.
Four sided fin heat exchanger with large ventilation, with internally threaded tubes and higher heat exchange efficiency.
The corrugated aluminum fin technology has fewer cuts, less corrosion and dust collection, and longer service life cycle.
Stainless steel vacuum brazed plate heat exchanger and double system cross diagonal flow structure, heat exchange is sufficient and more efficient.
High quality 480-class double electronic expansion valve with wide regulation range.
Dynamic and real-time matching according to actual load demand, with faster control speed and more accurate precision.
20-mesh Y-type filter is equipped to prevent impurities from entering the system and affecting the performance and reliability of unit, and facilitate the subsequent cleaning of the water system at the same time.
A single system of the commercial heat pump is equipped with multiple electronic expansion valves, which not only can avoid the shutdown risk caused by failure of the single electronic expansion valve, but also can realize the rapid and accurate adjustment of refrigerant according to the load demand and improve the heat exchange efficiency.
The pressure sensor and temperature sensor can detect the system temperature and pressure of commercial heat pump water heaters in time and automatically adjust the system to ensure the safety and efficient operation of the commercial air to water heat pump.
Equipped with the electric heating belt for compressor crankcase and design of large-capacity gas-liquid separator to avoid a large amount of liquid refrigerant directly entering the compressor.
Separation of strong and weak current, which is safe and reliable; troughing design makes wiring tidy and safe; anti-reverse connection design to avoid damage due to reverse connection unit of power cord; overload protection can automatically power off when current is too high; overall waterproof design with higher safety.
As the basic module, the Polestar E series commercial heat pump hot water heater can be mixed and spliced with the Polestar EVI series commercial hot water heat pump and other commercial heat pump systems series to meet different engineering requirements.
Each commercial heat pump is equipped with a Y-type filter and differential pressure sensor as standard. ln case of water shortage, no water, and dirty blockage of the water system, the air source heat pumps for commercial buildings can be protected in time without damaging the evaporator.
The commercial air source heat pump water heater is equipped with a two-way valve control port as standard, which can automatically control the flow of the water pump according to the actual flow demand, thus easily realizing the variable primary flow system.
The components of the commercial building heat pumps are evenly distributed around the commercial heat pump, and the lower half metal plate of the unit is fully enclosed, and the unit can be inspected and maintained by disassembling the panel.
Automatically analyze the cause of the fault according to the operating parameters of the system, which can guide the quick solution to the unit malfunction.
