INSTALLATION MANUAL
1. INTRODUCTION
1.1. About air to water chiller
Air to water chillers provide cold (and hot (only for EWYQ)) water for
a large variety of applications such as for airconditioning of buildings
(for this application the units can be combined with Daikin fan coil
units or air handling units) but also for the cooling and heating of
industrial processes.
In cooling mode, the heat returned from the application is discharged
to the air. In heating mode, the heat to be added to the application is
retrieved from the air.
The main components are
■ the compressor,
■ the air heat exchanger,
■ the water heat exchanger.
The compressor 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.
1.2. About this air to water chiller
The units are designed for outdoor installation (cooling: –15°C to
43°C, heating: –15°C to 35°C) (for details see technical data book).
The units are available in 7 standard sizes with capacities ranging
from 16.8 to 63 kW. All sizes are available as cooling only unit and as
heat pump unit (cooling/heating).
