29、l systems. Typical applications are low temperature radiant heating and high temperature radiant cooling. They are classified as embedded radiant heating and cooling systems and prefabricated radiant heating and cooling panel systems. While ISO 11855 is for embedded radiant heating and cooling syste

30、ms without an open air gap, ISO 18566 is for 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

31、and heating capacity and control and operation.ISO 18566-1 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 hea

32、ting and cooling capacity of ceiling mounted radiant panels. 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 int

33、ended in the design stage when the system is actually being operated in a building.ISO 18566 does not cover the panels that are embedded into the ceiling, wall or floor structure.

The control INTERNATIONAL STANDARD ISO 18566-4:2017(E) ISO 2017 All rights reserved 1BS ISO 185664:2017ISO 18566-4:2017(E)system shall be capable of varying heating or cooling outputs as well as maintaining predetermined

41、room or surface temperatures.Control of the heating and cooling system shall enable the specified designed indoor temperatures to be achieved under the specified variation of internal loads and external climate. The control system shall, if specified, protect buildings and equipment against frost an

42、d moisture damage where necessary (when normal comfort temperature level is not required) and prevent condensation from occurring.The design of the control system shall take into account the dynamics of the space, its intended use and the effective functioning of the panel system. It shall also ensu

43、re efficient use of energy and avoid conditioning the space to full design conditions when not required. This shall include keeping distribution heat losses as low as possible, e.g. by reducing flow rates and temperatures, when normal comfort temperature level is not required. Control of the system

44、will enable control of the conditioning systems to obtain possible savings of operational costs and enable the maintenance of required indoor environmental conditions. The control shall ensure that heating and cooling does not occur at the same time in the same space.In order to maintain a stable th

45、ermal environment, the control system needs to maintain the balance between supplied energy from the system and the losses/gains of the space environment under transient conditions. Slowly varying energy flows in the form of energy losses or gains through the envelope are determined by indoor and ou

46、tdoor temperature, and direction and speed of wind.2 ISO 2017 All rights reservedBS ISO 185664:2017ISO 18566-4:2017(E)system shall be capable of varying heating or cooling outputs as well as maintaining predetermined room or surface temperatures.Control of the heating and cooling system shall enable
