Riello NXHM Inverter Monobloc Air-Water Hydronic Heat Pumps

NXHM is a highly energy efficient residential hydronic heat pump for heating, cooling and possible production of domestic hot water. The unit operates with environmentally friendly R32 refrigerant, ensuring not only low global warming potential (GWP) and CO ₂ emissions, but also high energy efficiency throughout the entire operating range.

NXHM is also equipped with new exchange batteries with the special hydrophilic and anti-corrosive Blue-Fin treatment, which improves the drainage of condensation on the fins, thus reducing the risk of freezing on the battery (maximum efficiency even in humid climates)

NXHM is available in 10 different models with heating capacities from 4.2 to 15.9 kW

Structure

Covering cabinet made of steel sheet painted with neutral RAL 7035 powders which increases its resistance to corrosion by atmospheric agents. All panels are removable

Compressor

A double compressor protection screen for sound insulation further reduces noise levels. Advanced technology, capable of offering maximum energy efficiency and characterized by high power available in peak conditions, as well as optimized performance at low and medium compressor speeds. The NXHM heat pump is equipped with DC inverter technology, which combines two electronic regulation logics: go modulation (PAM) and pulse width modulation (PWM), in order to ensure optimized compressor operation in all operating conditions, minimize temperature fluctuations, and provide perfect comfort regulation and, all this, significantly reducing energy consumption.

PAM

DC pulse width modulation controls the compressor at maximum load conditions (start and peak load), so as to increase the voltage at a fixed frequency. The compressor operates at high speed, so as to quickly reach the desired temperature

PWM

Pulse width modulation of the direct current controls the compressor under partial load conditions by adapting the frequency to a fixed voltage. The compressor speed is precisely regulated, and the system offers a high level of comfort (no temperature fluctuations) under operating conditions with exceptional efficiency. The compressor frequency increases continuously until it reaches the maximum level. This ensures that there are no peaks in intensity during the start-up phase and also guarantees a safe connection to a single-phase power supply, even for high-power systems. This compressor start logic makes “Soft Start” starters unnecessary and also ensures that maximum power is immediately available

External Battery

The external battery is made with copper tubes and hydrophilic aluminum fins. This solution allows water to migrate more easily (by gravity) towards the bottom of the exchanger. In particular, this innovation allows:

• lengthening the time required for frost to form, reducing its accumulation on the battery

• a more efficient defrosting phase, thanks to the improved water flow on the fins; thus, operation in heating mode is improved

Standard blue coating treatment that improves the resistance of the batteries to corrosive agents and is recommended in all those applications that present a moderate risk of corrosion

External Fan

Single Brushless DC fan motor with variable speed for optimal air distribution combined with exceptionally low noise levels. Possibility to set two different maximum noise levels

Electronic expansion valve

The electronic expansion valve is an electronic bi-flow expansion device, whose task is to optimize the volume of the refrigerant fluid present in the circuit and consequently the overheating, preventing the return of the fluid in liquid phase towards the compressor. This device further improves the high efficiency and reliability of the system, as it allows to work even with very low condensation pressures in the entire working range.

Solenoid valve

Given the extended working ranges of the unit, the solenoid valve, completely managed by the unit, allows the compressor to work at always optimal temperature levels.

Plate exchangers

Vertical plate heat exchanger in AISI 316 stainless steel

Integrated hydronic group

The hydronic module is always present and is supplied with a variable speed circulation pump, flow switch, 3 bar safety valve, expansion vessel and inlet and outlet water temperature probes. The electric backup heater can be supplied as an accessory. In domestic applications, the inertial storage tank can be connected directly under the unit in order to minimise the space occupied inside the living spaces. All internal hydronic parts are insulated to reduce heat loss. The antifreeze program contains special functions that use the heat pump and the backup heater (if available) to protect the entire system from freezing. When the temperature of the water flow in the system drops to a certain value, the unit will heat the water, either with the heat pump, or with the electric heating tap, or with the backup heater (if available). The antifreeze protection function is deactivated only when the temperature increases to a certain value
