MCP

The ever-increasing need to reduce energy consumption and increase production efficiency of chilled water for air conditioning and hot water for heating and the domestic water supply, combined with the need to make these processes independent of each other and the operating season, finds its full achievement in the new Galletti MULTI-PURPOSE MCP units.

The term “multi-purpose” refers to a machine that is capable of complete heat recovery during the summer period (not temporarily reversing the cycle, for the purpose of producing sanitary hot water, with the resulting inevitable losses in efficiency and comfort). Therefore, this is the so-called “4-pipe” unit that must be hydraulically connected to two distinct systems: the first one is for heating and air conditioning the building and the second one is for producing domestic hot water. The multi-purpose MCP units have been designed to cool and heat water for air conditioning and heating systems and for the production of DHW for residential or commercial use.

The units are “real” multipurpose units, with 4 water collections, whose operating modes are described below:

1. Cold water production in summertime mode, for the air conditioning system (air condensing system on the finned exchanger)

2. Cold water production in the summertime mode, for the air conditioning system, with TOTAL CONDENSATION HEAT RECOVERY (for the production of DHW by means of a dedicated plate exchanger)

3. Production of hot water in wintertime mode, for the heating system, functioning as a traditional heat pump (air evaporation on the heat exchanger side and water condensation on the dedicated plate heat exchanger on the system side)

4. Domestic hot water production in wintertime mode, temporarily stopping hot water production for air heating purpose (DHW priority)

5. DHW production only (in particular in mid seasons and in summertime and wintertime)
