29、stems: ceiling mounted radiant panels, chilled beams, pipe embedded ceilings, walls, and floors. In those system alternatives, ceiling mounted radiant panels are widely used and frequently installed on T-bar grids designed to support the dropped acoustical ceiling. The ceiling mounted radiant panels

30、 are top loaded with thermal insulation to prevent heat gain from or loss to the plenum space. In some cases, free hanging metal panels suspended under the room ceiling by wire hangers without topside insulation are also used for space heating and cooling. Both top and bottom surfaces of the free-ha

31、nging metal panel are used as heat transfer surfaces. In principle, ceiling mounted radiant panel systems are able to accommodate varying space sensible loads by controlling panel surface temperature. Heat is transferred from the radiant panel by the heat transfer mechanisms of convection and radiat

32、ion.Generally, low temperature radiant heating and high temperature radiant cooling are classified as embedded radiant heating and cooling systems and ceiling mounted radiant panel systems. While ISO 11855 is for embedded radiant heating and cooling systems without an open air gap, ISO 18566 is for

33、radiant heating and cooling panel systems with an open air gap. Because the system specifications for ISO 18566 are different from those of ISO 11855, it was necessary to develop separate ISO standards regarding the design and test methods of the cooling and heating capacity and control.ISO 18566-1

34、specifies the comfort criteria, technical specifications and requirements which should be considered in the manufacturing and installation of radiant heating and cooling systems. ISO 18566-2 provides the test facility and test method for heating and cooling capacity of ceiling mounted radiant panels

35、 ISO 18566-3 specifies the design considerations and design processes of ceiling mounted radiant panels. ISO 18566-4 addresses the control of ceiling mounted radiant heating and cooling panels to ensure the maximum performance which was intended in the design stage when the system is actually being

36、 operated in a building.ISO 18566 does not cover the panels that are embedded into the ceiling, wall or floor structure.This document is partly based on EN 14240, EN 14037 and ASNI/ASHRAE Standard 138.

44、r cold water through a network of pipes placed on the floor, wall or ceiling. Heat is gently radiated from these radiant panels into occupied spaces, warming or cooling the objects in the area to create a comfortable environment. Radiant heating and cooling panels can be installed in a single room o

45、r throughout an entire building, and it is used for areas with normal and high ceilings. A variety of heat sources can be used, including boilers, geothermal heat pumps, solar thermal systems and electric water heaters.Ceiling mounted radiant panels function as heat exchangers between the room air a

46、nd the chilled/hot water. The ceiling panels absorb or emit heat from heat sources in a room and exchanges it with the circulating chilled/hot water. The chilled or hot water is then pumped to a chiller or boiler. With radiant panel systems, room thermal conditions are maintained primarily by direct

47、 transfer of radiant energy, rather than by convection heating and cooling. Radiation of energy takes place between objects with different surface temperatures. In order to provide acceptable thermal conditions, air temperature and mean radiant temperature should be taken into account. See Annex B f

48、or details about heat transfer by panel surfaces.Compared with a conventional convective heating and cooling system, a radiant heating system can achieve the same level of operative temperature at a lower air temperature and a radiant cooling system at a higher air temperature. However, in all pract

49、ical thermal environments, a radiation field has an asymmetric feature to some degree. If the asymmetry is sufficiently large, it can cause discomfort. Also, the thermal stratification of air may cause thermal discomfort. Therefore, these comfort criteria should be considered in the design stage of ceiling mounted radiant panels. Ceiling mounted radiant panels are generally built as an architectural finish product. Generally, the copper pipes are thermally bonded and panel piping arrangements are in
