Air chillers and heat pumps MPI DC Outdoor monobloc unit with BLDC compressor MPI DC - 9 kw Large operating range and energy efficiency under every condition BLDC scroll compressor PLUS BLDC rotary compressor R-0A R-0A refrigerant Cooling only Cooling / Heating Monobloc unit Axial fans Twin-rotary or scroll compressor driven by an electronic control BLDC motor Electronically controlled electric expansion valve Modulating hydraulic pump with stainless steel impeller Incorporable inertial tank Access to the tax incentives provided for energy retrofitting The MPI DC series consists of heat pump models and cold only models and is intended mainly for residential or light commercial applications. Due to the control managed by a software program developed by Galletti, the MPI DC series adjustment logic makes it possible to adjust the water delivery temperature to the set value and to control the compressor so that the power generated by the machine is adjusted to the thermal load required by the system. This represents a strategic feature in the limiting of energy consumption, because the effective thermal load of an air conditioning system is less than 0% of the nominal load most of the time. The BLDC technology upon which is based the compressor s electric motor guarantees the ability to change the rotation speed in a frequency range between 0 and 0 Hz, thereby reducing at the same time the power consumption and thus maintaining a high level of efficiency in the operation at partial load and improved isentropic efficiency. These units large operating range, which is also achieved due to the variable flow water circulator they are equipped with as a standard feature, guarantees operation with air temperatures from - C up to C, while in heating mode it is possible to produce hot water up to C. This allows their use as a single generator in addition to summer air conditioning, even in medium-temperature heating systems and for the production of DHW. Furthermore, the innovative Smart Defrost System guarantees that defrosting always occurs in the most efficient manner even under the most extreme environmental conditions. MPI DC can be the only heat generator in low-power systems due to its large operating range that includes both low winter temperatures and high summer temperatures. galletti.com VM000-C
MPI DC - 9 kw MAIN COMPONENTS Structure It is constructed of galvanized and painted sheet metal that is resistant to corrosive agents. Compressor compartment closed and accessible from three sides due to easily removable panels, available also with internal coating of soundproofing material. Compressor Heat exchanger Electronically controlled electric expansion valve Hermetic twin-rotary or scroll compressor driven by a permanent magnet BLDC motor and controlled by a trapezoidal wave inverter. It is attached to the base by means of rubber dampers to reduce the transmission of vibrations. Finned heat exchanger constructed with copper pipes mechanically attached to aluminum fins, carefully designed to minimize the defrosting phases and optimize heat exchange efficiency in every operating phase. Key component for the proper functioning of the unit. The PID control algorithm allows it to quickly adapt to all operating conditions and to keep the cooling cycle stable. Hydraulic kit Variable flow centrifugal circulator with stainless steel impeller. An expansion vessel and the automatic filling tap are also included. An inertial buffer tank built into the structure is available as an optional accessory. DHW kit A system that makes it possible to transform the MPI DC heat pumps into multi-purpose units that are able not only to meet the requirements of the air conditioning system, but also to produce domestic hot water as a priority by means of the Galletti TP or TN series thermal storage tanks. It is comprised of a microprocessor control unit with LCD display and a -way motorized valve. Also, anti-legionnaire s disease cycles can be activated by means of a heating element.
