HFC based chiller and heat pump systems installed for innovative modular hospital ward
HFC based chillers and heat pumps were installed at a hospital’s new modular ward in the UK, a facility that will help shape construction of future National Health Service (NHS) hospitals in the UK. Two R-32 chillers with air-source heat pumps are used for heating and two R-407C based heat pumps deliver hot water for the 28-bed ward. One hundred percent fresh tempered air needs to be delivered to each ward and isolation area at up to 15 changes an hour. This creates a constant cooling or heating demand depending on the season, which the chillers and heat pumps successfully deliver. The energy efficiency of heat pumps is also a considerable benefit for hospitals – they are extremely energy-efficient and classified as renewable energy.
The chillers are based on quiet-running scroll compressors, which deliver on the ward’s need for decibel levels to be kept low for patients to rest. The heat pumps and chillers, running on a low global warming potential (GWP) refrigerant [R-32], will help the NHS meet its 2040 net zero goal. The units have a Building Research Establishment Environmental Assessment Method (BREEAM) excellent rating.
