DR Suite Cooler Unit – Broomfield Hospital

Tender description

MEHT wishes to receive tenders for the design, manufacture, supply, delivery to site, off-loading, moving to place of work, protecting, assembly, installation, testing and commissioning of DR Suite Cooling Unit at Broomfield Hospital. As part of a programme of works aimed at building extra resilience into the Disaster Recovery (DR) computing centre at Broomfield Hospital the DR management team has identified the need for a dedicated chilled water installation that is suitable for supplying the needs of fan coil units fitted inside the DR computer suite. The new system will be connected into existing flow and return pipe work in such a way that cooling can be provided by either the new chiller (DUTY) or the existing Trane chiller (STANDBY). It is required that the proposed chilled water system must also be configurable as a heat pump, in such a way that domestic hot water (DHW) heating as well as DR air conditioning functions can be simultaneously (or separately) managed from the same machine. Although MEHT is procuring the DR Suite Cooler Unit, the successful bidder will be expected to potentially enter into a novation agreement with the successful Mechanical & Electrical Contractor who will be carrying out the enabling works and acting as Main Contractor . The bidder is to indicate within his tender if he has any reasonable objections as to why a novation may not be entered into with the successful Mechanical & Electrical Contractor. Design Criteria The proposed installation is required to operate on the vapour-compression refrigerating principle and as well as producing chilled water is to be fitted with a heat recovery system of the type used in heat pump installations (in which the entirety of the energy entrained in the high pressure side of the refrigerant circuit is recoverable for water heating). Refrigerating systems which are capable only of partial heat recovery from the high pressure refrigerant circuit (eg
