3 About the units and options
3.1 Identification
3.1.1 About the outdoor unit
SERHQ outdoor units are designed for outdoor installation and are
meant to be combined with SEHVX indoor units.
The outdoor units are designed to work in heating mode at ambient
temperatures from –15°CWB to 35°C WB and in cooling mode at
ambient temperatures from –5°CDB to 43°CDB.
3.1.2 About the indoor unit
This installation manual concerns the inverter heat pump chilling unit
with separate hydro module. The unit is intended for indoor
installation and can be combined with VRV outdoor units
(SERHQ020+032BAW1) for air conditioning purposes, or it can be
used for supplying water for process cooling applications.
The units are available in 4 standard sizes with nominal capacities
ranging from 16.8 to 63 kW.
The unit is designed to work in heating mode at ambient
temperatures from –15°C to 35°C and in cooling mode at ambient
temperatures from –5°C to 43°C.
The main component is the water heat exchanger.
The indoor unit is connected to the outdoor unit by field refrigerant
piping and the compressor in the outdoor unit circulates refrigerant
into the heat exchangers.
▪ In cooling mode, the refrigerant transports the heat taken from the
water heat exchanger to the air heat exchanger where the heat is
released to the air.
▪ In heating mode, the refrigerant transports the heat taken from the
air heat exchanger to the water heat exchanger where the heat is
released to the water.
