17、agreement with UMRL dated March 2008*SECTION 23 81 47WATER-LOOP AND GROUND-LOOP HEAT PUMP SYSTEMS04/08*NOTE: This guide specification covers the requirements for water source heat pump systems and ground source closed-loop heat pump systems.This specification is based on two contract approaches for
18、providing these systems: separate design and contractor installed systems (Design-Bid-Build) and contractor design and installed systems (Design-Build or performance based contracting). The designer selects required preference for the contract approach. Contractor design and install is limited to gr
19、ound source closed-loop heat pump systems.Edit this guide specification for project specific requirements by adding, deleting, or revising text. For bracketed items, choose applicable items(s) or insert appropriate information.Remove information and requirements not required in respective project, w
20、hether or not brackets are present.Comments and suggestions on this guide specification are welcome and should be directed to the technical proponent of the specification. A listing of technical proponents, including their organization designation and telephone number, is on the Internet.Recommended
21、 changes to a UFGS should be submitted as a Criteria Change Request (CCR).Tailoring is provided in this specification for Army, Navy, and Design-Build. The use of tailoring will remove the unwanted specific agency requirements.*SECTION 23 81 47 Page 4Provided by IHSNot for ResaleNo reproduction or n
22、etworking permitted without license from IHS-,-,-NOTES:1. There are two main types of ground source heat pump system: closed loop systems and open systems. Open systems use and dispose of ground water. There are variations of closed loop systems based on the configuration of pipe orientations. This
23、specification covers only closed-loop systems. This specification also covers water loop systems that are pf the not ground-source type.2. System design requirements must conform to Unified Facilities Criteria (UFC) 3-410-01FA Design: Heating, Ventilation, and Air Conditioning“, UFC 3-410-02N Heatin
