Chillers
Choosing and sizing a chiller; applications such as injection moulding and concrete cooling.
Concrete cooling: chillers, ice and cooling pipes for mass concrete
Hydration heat cracks thick pours. How chilled mixing water and ice lower the placing temperature, how embedded pipes cool the core, and how to size the chiller.
Chiller selection: capacity calculation, water temperature and key factors
Capacity from flow and temperature difference, leaving water temperature, glycol, N+1 redundancy and the installation site: the questions to answer, in order, when choosing a chiller.
History of the chiller: from the ice trade to today's water chillers
From the 1806 ice shipments to Carrier's 1902 air conditioning system and his 1922 centrifugal machine: how the chiller became today's inverter-controlled, low-GWP unit.
Injection moulding machine cooling: the right water for mould and oil
Mould water sets cycle time and part quality; oil cooling keeps the machine stable. Which circuit gets which water, and how to size the chiller.
