Room-based heat pump
The Illustrated Guide to Mechanical Building Services, Third Edition (BG 31/2017), by David Bleicher, published by BSRIA in 2017, describes room-based heat pumps as:
‘Individual room units, which can be floor standing or concealed in a void, such as the ceiling, are all linked by a piped water circuit that runs around the building. Each unit operates independently and is able to heat or cool the air in the immediate area. This is achieved by means of a small heat pump in the unit which takes low grade heat from the water circuit and uses it to heat the room. To cool the room, the heat pump works in reverse to remove heat from the space and transfer it to the water circuit.
‘A key benefit of this type of system is the ability to save energy by transferring heat from an area where it is not needed to an area where it is. Any additional heating required by the system is provided by either a small boiler, electric heater or a link to a separate hot water circuit in the building. Any additional cooling is performed by one or more dry coolers or cooling towers which remove waste heat from the water circuit. As with fan coil systems, a separate ventilation system is be (sic) required.’
