Case Studies - Cooling the Workshop

The engineering workshop at Premier Foods, Bury St Edmunds UK had a requirement for heating and cooling.

The combined heating and cooling system was based on a single EcoCooler.

The fan from the cooler was relocated into the ductwork after a recirculation loop. This created a roof mounted ‘wet box’ which can provide either ambient or evaporatively cooled air and a recirculation loop which, using a steam heating coil, provides a source for heating.

There are two modes of operation:

Summer mode:

Cooler operates conventionally with five speeds and ‘Cool’ or ‘Vent’ Modes. Inlet damper is open and recirculation damper is closed.

Winter mode:

Air is heated using a steam coil controlled from a thermostat. The fan runs at a fixed speed. The inlet damper is closed and the recirculation damper is open.
