ONE CROWN PALACE CASE STUDIES One Crown Place is a dramatic, gleaming new addition to the London Iconic skyline. A building that challenges the perception of what the City Both HIU and CIU were fitted as standard with Ultrasonic heat stands for today, radiating confidence from its warm glow and and cooling meters, allowing the building owners to geometric silhouette and offering a welcome antidote to independently meter and bill the homeowners the own usage. ubiquitous concrete and glass towers. The keep warm facility was designed so the homeowner / YGHP were commissioned to find a solution to the heating and Hot water demands for this development. The challenge was to find a Heat interface unit (HIU) and Cooling Interface unit (CIU) That had the performance to test against BESA HIU regime, but also physically would not take up to much valuable space for the home owner within the utility cupboard. With HIU kW ranges from 53.5kW to 91kW YGHP were able to offer the YGHP Indirect series. Keeping the footprint, the same throughout the range. The Unit offered was a Hydraulic unit, that gave all the benefits of stable control and lower fluctuation issues than experienced with Electronic HIU’s. The design criteria for the DHW was based on 75/35 with the space heating load 75/45. Independent witness testing was arranged tenant could make a choice, did they warm instantaneous DHE with the keep warm on, a cost to the homeowner to keep the DHW Plate heat exchanger warm. Or turn the DHW keep warm off in times on non-occupancy. A benefit of no primary water going through the Heat / Cooling meters and allowing the building corridor primaries to also cool. A total of 235 HIU and CIU were supplied, installed into a off-site prefabricated utility cupboard. YGHP worked with the PUC manufacture to ensure the units physically matched. In order to meet the programme requirements, the units were built with a buffer stock of two months scheduled deliveries in mind. to prove system design against practical performance. OCP proved YGHP can take on the most challenging of Cooling interface Units were designed to fit the same footprint HIU-CIU. projects and deliver quality and value for money with a range of 3kW to 17kW. The design criteria were a secondary flow rate of 9/15.C Again YGHP were able to The YGHP Indirect Series. provide witness testing for the Cooling units. INDIRECT SERIES Heat interface units are a complete solution for apartments for hydraulic separated systems. Secondary system can be radiators or underfloor heating. Balancing valves can be radiators or underfloor heating. Stainless steel heat exchanger and thermostatic controlling valve to have a stable temperature domestic hot water up to 23 It/min. Stainless steel heat exchanger is used to hydraulically separate the apartment from the main system. Thermostatic controlled valves are used to control the secondary side supply temperature. Energy efficient electronically controlled pump controls the flow of secondary side heating. All the consumption of heating and domestic hot water preparation can be measured by one heat meter and cold water meter. All the piping is stainless steel.
