High-performance chillers

01 July, 2004

An average COP of 5.7 is claimed for a range of water-cooled liquid chillers from Delrac. There are 18 models in the EWH range of single- and twin-circuit chillers. They are designed for use with R134a and offer cooling capacities from 105 to 1204 kW. The high performance is attributable to a dedicated heat-exchanger design and specially refined screw compressor. These chillers use counter-current, dry-expansion shell-and-tube evaporators. The evaporators also allow the chillers to be smaller, and they use less refrigerant than other designs. Options include electronic expansion valve, modulating capacity steps, safety water flow switch, liquid injection, rubber type vibration damper, spring vibration damper, remote micro-processor, compressor suction shut-off valve, RS485 serial interface, anti-freeze electric heater, compressor overload relays and compressor oil-level switch. sales@delrac-london.co.uk

More refrigerant bans possible, says government

The government could tighten up the rules that restrict the use of global warming refrigerant gases including speeding up phase-out programmes and introducing new bans, according to a spokesman from the Department for Environment, Food and Rural Affairs (DEFRA).

Baxi research suggests schools strongly support heat decarbonisation

A survey conducted by Baxi of 200 state school estates managers, consultant engineers and M&E contractors has found that while enthusiasm for Net Zero and support for low carbon heating systems in schools is thriving, persistent barriers remain.
