Water chilling package and heat pumps, air condensation; outdoor installation
Description
MPE water chillers and heat pumps are designed for outdoor installation in both residential and industrial applications.
The range uses R410A refrigerant, which assures high levels of performance with relatively low energy consumption and features 29 models in heat pump version and 10 models in chiller version, with cooling capacities ranging from 20 to 71 kW and heating capacities from 5 to 85 kW.
BEYOND CONVENTIONAL WORKING LIMITS The finned block heat exchangers have been optimised for R410A and use 8 mm copper pipes, which permit a better heat exchange and quiet operation of the fans. Their generous sizing guarantees the production of chilled water even with outdoor air temperatures as high as 47°C.
EFFICIENCY IN ALL CONDITIONS The actual thermal load of an air conditioning system is less than 60% of the rated load capacity 90% of the time; the MPE T version with single-circuit dual compressor answers this demand by offering high efficiency during operation under partial load conditions (ESEER>4) and also guarantees the unit's operation at the worst temperature conditions. In such conditions the microprocessor controller activates the capacity control mode, doubling the condensing surface available to the single compressor.
SELF-ADAPTIVE CONTROL SYSTEM The electronic control system allows the setpoint to be adjusted automatically according to the outdoor temperature in order to reduce consumption and broaden the working temperature range. The unit can also function in systems with a low water content, even without the use of a water buffer tank, thanks to the automatic adjustment which limits the number of compressor starts and thus extends the life of the compressors themselves.
SMART DEFROST SYSTEM The exclusive defrost system (optional feature available with the advanced controller) can correctly identify an impairment of performance in the outdoor exchanger due to the formation of ice and minimise the process time in relation to normal operation of the unit.

Main components
Structure: galvanized and painted sheet steel carpentry (RAL9002)
Made-to-measure hydronic kits: the structure can house hydronic kits with pump, expansion tank and storage tank. High head pump made entirely of stainless steel already set up for use with mixtures of water and ethylene glycol up to 35% and equipped with internal thermal protection
Electronic control and microprocessor: The electronic control allows complete management of the MPE units and is easily accessible through a polycarbonate door, with IP65 protection degree. It implements the compressor regulation logic and allows the complete management of the other parts of the unit, the inversion of the refrigeration cycle and the alarms.
Finned pack heat exchanger: In 8 mm diameter copper tube and aluminum fins. The particular design criterion of the exchangers makes it possible to speed up the defrosting phases as much as possible in the heat pump versions with obvious benefits on the seasonal efficiency during heating operation.
