Operation and capacity
Operation and structure
The patented MeandRo system has been fully developed in-house at INTECO. The MeandRo-GA climate system consists of an expanded metal heat conductor, with a very open and fine structure. A copper pipe register has been soldered to this expanded metal. MeandRo-GA elements are inter-connected using flexible stainless steel hoses and then connected to the distribution pipes. The MeandRo-GA element is fitted to a construction made from support profiles. Depending on the requirements, cold as well as hot water could pass through the element as an energy carrier. Thermal insulation is placed on top of the element. Multiple small contact surfaces ensure effective and uniform heat transfer between the MeandRo element and the ceiling surface. In addition, heat is transferred via radiation. The cooled and/or heated ceiling therefore functions as radiant ceiling.
Capacity of the MeandRo-GA elements
External factors like sunlight, transmission data for windows, walls and roofs, and internal factors like heat development via e.g. other people, electrical equipment and lighting, are used to define cooling and heating capacity per area when designing the climate system. This also involves taking into account variable effects like fluctuating solar load, heat accumulation due to e.g. concrete constructions, extraction via light fixtures, etc. The designer also determines the benchmarks implemented for comfort. Inteco then uses the design benchmarks to determine the displacement rate for the ceiling surface area. In most cases, the MeandRo-GA ceiling comfortably meets the required capacity.
The effective heat exchange, and the large heat exchange surface, means cooling capacities of approx. 67 W/m2; (?T = 8K) can be realised.
