GENERAL FEATURESUnit descriptionThis series of <strong>air</strong>-water heat pumps satisfies the heating,cooling and domestic hot water production requirements ofresidential plants of small and medium size.All the units are suitable for outdoor or indoor installation andcan be applied to fan coil plants, radiant floor plants and highefficiency radiators plants.The control system allows to manage not only the refrigerantcircuit but the whole plant with the possibility to choose differentsolutions both for the heating and cooling plant and for thedomestic hot water management. The possibility of solarpanels or other heating sources integration is also available.The heating function optimizes the flow water temperatureaccording both to the ambient temperature and to the outdoortemperature through climatic curves adaptable to the buildingfeatures. It’s possible to manage a storage tank and two independentcircuits (a direct one and a mixed one).The domestic hot water management allows to control thethree way valve, the storage tank and the anti-legionellacycles (if necessary).The cooling function can be realized through “active cooling”(refrigerant circuit inversion). When the unit is used in radiantfloor plants, to avoid condensate generation, a room humiditysensor can be installed.The internal programmer clock allows to define differentdaily switching programs for heating, cooling and domestic hotwater production.The refrigerant circuit, contained in a box rep<strong>air</strong>ed from the <strong>air</strong>flow to simplify the maintenance operations, is equipped withscroll compressor mounted on damper supports, brazed plateheat exchanger, electronic expansion valve, reverse cyclevalve centrifugal fan (plug fan), finned coil realized with copperpipes and alluminium fins. The circuit is protected by highand low pressure switches and flow switch on the plate heatexchanger.The plate heat exchanger and all the hydraulic pipes are thermallyinsulated in order to avoid condensate generation andreduce thermal losses.The plug fan with electronic control of the rotational speedguarantees high efficiencies and low noise in all the operatingconditions and allows to install the unit both outdoor (with protectioncaps) or indoor (with ducted <strong>air</strong> inlet and outlet).All three-phase power supply units are provided with a phasesequence and correct sequence controller device.All the units are accurately built and individually tested in thefactory. Only electric and hydraulic connections are requiredfor installation.Unit identification codeThe codes that identify the units and the meaning of the letters used are described below.HXP IP 16.1 VB AB 0 M 1Unit typeIP - Units suitable forhydronic plant installationoperating as reversible heatpumpsUnit versionVB - Base VersionUnit modelN° compressorsAcoustic setting upAB - Base setting upPower supply1 - 230V - 1 - 50 Hz5 - 400V - 3N - 50 HzOperating rangeM - Medium temperature.The unit is suitable to producewater at medium temperatureRefrigerant type0 - R410A5


GENERAL FEATURESDescription of componentsExternal structure. Basement, supporting structure and lateralpanels are made of galvanized and painted sheet-steel toguarantee good resistance to atmospheric agents.Accessibility to internal parts is possible removing the lateralpanels.

All the pipes of the refrigerantcircuit are properly insulated to avoid condensategeneration and minimize thermal lossesThe plug fan (8) is equipped with an high efficiency electronicallycommutated (EC) motor and guarantees enough availablestatic pressure to allow both the outdoor and the indoorinstallation.Hydraulic circuit. All the pipes are thermally insulated toavoid condensate generation and minimize thermal losses.The circuit can be equipped with a standard or a high head circulationpump (option). The circuit is always equipped alsowith expansion vessel and <strong>air</strong> vents.Refrigerant circuit. It is contained inside a compartmentseparated from the <strong>air</strong> flow to simplify maintenance and controloperations.The hermetic scroll compressor (1) is mounted on dampersupports and is protected against overtemperatures and overcurrents.It is equipped with an electrcal heater, that is activatedwhen the compressor turns off, to keep the compressorcrankcase oil temperature high enough to prevent migration ofthe refrigerant during winter stops and to evaporate any liquidpresent in the crankcase, in order to prevent possible liquidrushes on starting.The plant side heat exchanger (2) is a brazed stainless steelplate heat exchanger, properly insulated to avoid condensategeneration and to minimize thermal losses, and protected bya flow switch that detects whatever water flow lack.The source side heat exchanger (3) is a finned coil realizedwith grooved copper pipes and hydrophilic aluminium fins withwaved profile to increase the heat exchange coefficient. A trayis placed under the coil to collect the condensate generated inheating mode.Electrical panel. It contains all the power, control and securitycomponents necessary to guarantee the unit to work properly.The unit is managed by a microprocessor controller towhich all the electrical loads and the control devices are connected.The user interface, to be placed indoor, allows to viewand to modify, if necessary, all the parameters of the unit.All the units are supplied with an outdoor temperature sensor,to be installed outside, in order to realize the climatic control.8364The expansion device (4), an electronic expansion valve,allows the unit to adjust itself to the different operating conditionskeeping steady the set superheating.7The refrigerant circuit of each unit contains moreover solidcore hermetic filter dryer (5) to restrain impurity and moistu-2156
