Page 8: Technical Characteristics
N‐i‐HP Inverter air / water heat pump chillers with axial fans 5 TECHNICAL CHARACTERISTICS The N‐i‐HP water chillers and heat pumps series are designed for applications in residential and industrial areas, these units are extremely versatile and can operate in heat pump mode with the ability of hot water generation at a temperature of 55°C for environmental heating and sanitary applications. The DC Brushless Inverter compressor technology, matched with the electronic expansion valve, the pump and the variable speed blower are generally used for optimizing the power consumption and efficient operation of the refrigerating components. 5.1 FRAME All N‐i‐HP units are made up of hot‐galvanised thick sheet metal, painted with polyurethane powder enamels at 180°C to ensure the best resistance against atmospheric agents. The front panel is hinged to the lift side to allow access to the internal components for inspection and maintenance. The screws and the inserts are made up of galvanized steel. ... -
Page 9: Monitoring And Protection Devices
N‐i‐HP Inverter air / water heat pump chillers with axial fans The INVERTER system allows to reduce the plant’s water content to its minimum from the usual value 12‐15 liters/kW to 75 liters for the model N‐i‐HP 0125, 105 liters for the model N‐i‐HP 0235 and 150 liters for the modelN‐i‐HP 0250 in ABSOLUTE. Because of the reduced water content, the N‐i‐HP units can be installed in plants without water tank with advantages of the reduced size of the appliance, the installation spaces, heat losses and installation and maintenance costs of the plant. 5.9 MONITORING AND PROTECTION DEVICES The units are standard equipped with the following control and protection devices: return water temperature sensor installed on the return water pipe line from the plant, operating and antifreeze sensor installed on the outlet water pipe to the plant, high pressure transducer, low pressure transducer, compressor’s inlet and outlet temperature sensors, thermal protection device for fan motors, water side water flow switch to protect the evaporator, high pressure HP flow switch. CAUTION: The INVERTER control system is able to manage minimum water contents in the plant up to a value of 75 liters for the model N‐i‐HP 0125, of 105 liters for the model N‐i‐HP 0235, of 150 liters for the model N‐i‐HP 0250, and of 45 liters for the 15 model. This value makes reference to the liters absolute value and not to any kW of installed power. 5.10 HYDRAULIC CIRCUIT ... -

TA 1 Not available. 2 Not available. 0 Without vapour injection. IV 1 The vapour injection allows to increase the efficiency of the compressor especially in the critical conditions (air temp. <7°C or >35°C). The configuration with external pump without management in parallel includes the installation of a piece of pipe in the place of the 0 circulator. N.B.: the external pump is not supplied. The configuration with integrated circulator provides a modulating pump with brushless motor, suitable for the use of chilled water and CI 1 directly managed by the controller on‐board unit. The configuration with external pump with management in parallel requests the installation of an ON/OFF motorized valve instead of the 2 circulating pump, in order to exclude the unit if requested by the management of multi unit parallel. N.B.: the external pump is not supplied. 0 Unit not equipped with anti‐freeze kit. KA The antifreeze kit uses a self‐regulating heating cable wrapped around the basement of the unit near the condensing coil and two in PET 1 heaters placed on the faces of the plate heat exchanger. 0 Unit not equipped with management module for plant GI The additional module implements some useful functions for the plant management, such as sanitary hot water SHW, double setpoint, ... -

Page 27: Operating Limits
20 OPERATING LIMITS 20.1 EVAPORATOR WATER FLOW RATE The nominal water flow rate is referred to a ∆T equal to 5°C, between the evaporator’s inlet and outlet temperatures. The allowed maximum flow rate is corresponding to ∆T=3°C. Higher values may produce too high pressure drops. The allowed minimum water flow rate is corresponding to ∆T=8°C. Insufficient values may produce too low evaporating temperatures with the intervention of safety devices which would stop the unit and, in some particular cases, the water can freeze in the evaporator coil which can breakdown the refrigeration circuit. We enclosed below a most accurate table showing the minimum flow rates that to ensure for the plate heat exchanger for a the proper operation of unit according to the model (note: the water flow switch is used for preventing the freezing sensor from failure in the case of insufficient water flow but it does not ensure the minimum flow rate required in order the unit can work ... -
