AIR-TO-WATER HEAT PUMP HEATING SYSTEM 38AW/80AW
The XP Energy heat pump systems have an extremely high energy efficiency ratio in both cooling and heating mode, ensuring significant energy savings. Large and efficient coils and optimised circuiting feature ensure that all the combinations meet the European tax rebate efficiency targets. Efficiency at part-load conditions (seasonal energy efficiency) reaches the highest level in the industry. Year-round comfort: The advanced technology used in the new XP Energy heat pump condensing units provides optimised comfort levels for the end users, both in terms of water temperature control and silent operation. The desired temperature is quickly reached and effectively maintained without fluctuations. The XP Energy offers optimised individual comfort levels - both in winter and in summer. Wide temperature operating range: XP Energy heat pumps can operate efficiently in extreme temperature conditions. For end user comfort the units operate down to -20 °C outdoor temperature in heating mode, and in the summer, they produce hot water up to 60 °C at up to 30 °C outside temperature for domestic hot water applications.
Specially shaped anchorage feet ensure correct and safe fixing of the unit. The programmable NUI thermostat periodically runs system checks to monitor and assess the unit operating parameters. If a problem occurs, troubleshooting fault codes and messages help the service technician to identify the fault.
DC inverter twin-rotary compressor
Advanced technology provides maximum energy-efficiency with high capacity available at peak conditions and optimised efficiency at low and mid compressor speeds. The XP Energy heat pump DC inverter uses Intelligent Power Drive Unit (IPDU) hybrid inverter technology, combining two electronic management logics: Pulse Amplitude Modulation (PAM) and Pulse Width Modulation (PWM) for optimised compressor operation in all conditions, minimised temperature fluctuations, and provides perfect individual comfort control with significantly reduced energy consumption: - PAM: Pulse Amplitude Modulation of the direct current controls the compressor at maximum load conditions (start-up and peak load), and increases the voltage at ﬁxed frequency. The compressor works at high speed to rapidly achieve the desired temperature. - PWM: Pulse Width Modulation of the direct current controls the compressor at partial load conditions, and adjusts the frequency at ﬁxed voltage. The compressor speed is ﬁne-tuned and the system provides high-level comfort (no temperature ﬂuctuations) at exceptionally efﬁcient working conditions. Compressor frequency is increased continuously up to the maximum level. This ensures that there are no current draw peaks in the start-up phase and safe connection to a single-phase power supply even in large-capacity systems. The maximum operating current of XP Energy systems is below 12 A (systems up to 6.5 kW) and below 23 A for larger systems (up to 11.5 kW). Inverter rampup speed makes soft starts unnecessary and ensures immediate maximum power. The two rotary compression cylinders, offset from each other by 180°, and the DC brushless motor with the shaft in perfect balance ensure reduced vibration and noise, even at very low operating speeds. This results in an extremely wide range between minimum and maximum capacity with continuous operation, guaranteeing that the system is always optimised and provides maximum comfort at exceptionally high efficiency levels. Twin-rotary cylinders, low vibrations and low load to the shaft ensure highest compressor reliability and a long trouble-free operating life. All DC brushless twin-rotary compressors are equipped with crankcase heaters as standard. A double compressor shield for acoustic insulation further reduces noise levels.
