Colt International LtdWater-Source Air Conditioning Systems (WRF)Colt International Ltd designs and manufactures water source heat pump
systems. These are designed to provide minimal environmental impact, as
well as to meet the requirements of the F-Gas Regulations. Water-Source Heat Pumps SystemsCaloris WRF systems are based on a decentralised, locally controlled arrangement of quiet, slim, indoor heat pump units. Simple to install, economical to run, and low in noise output, these systems are especially suitable for use in offices, sports and leisure facilities, residential buildings, retail buildings, hotels and schools. Control SystemsCaloris WRF systems employ a decentralised control system, which enables the close and individual control of the internal space. Controls are available in either analogue or digital versions, and these may be connected to a building management system. OperationCaloris WRF systems can comprise three main components: Indoor heat
pump units for each controlled area; an external energy source (e.g. a
central air to water heat pump or ground source etc); and a neutral
water
loop, which provides the means of distributing energy between the
water-based heat pumps. Composition & ManufactureCaloris WRF indoor heat pump units are manufactured by Colt International in the UK. Every unit produced undergoes a complete functional test. New routines have been developed in the company’s Havant factory with the aim of achieving zero-defect production processes. DimensionsHorizontal indoor heat pumps measure 247mm in depth, or 339mm in depth in the case of size 7 version. This makes them amongst the slimmest available, and allows them to be installed within most ceiling voids. Vertical indoor heat pumps measure less than 500mm in height, which enables them to be installed directly under windows. Technical DataCaloris WRF systems provide excellent performance. Depending on water
temperatures, indoor units have an energy efficiency rating (EER) of
3.7-6.4.
Outdoor units have CoP’s of between 3-5 and EER’s of 4-5 (= an SPF of
30-40). InstallationIndoor Heat pump units are connected by a two-pipe water loop. Cross linked polyethylene pipework reduces installation time and costs. There is no limit to the lengths of pipe-work because, as a water-based technology, Caloris WRF systems do not have to pump refrigerants around a building. Technical SupportColt provides a comprehensive support service, including system design,
manufacture, project management, installation, commissioning and
maintenance.
