Encapsulation. Any covering or coating that acts as a barrier between LBP and the environment, the durability of which relies on adhesion and the integrity of the existing bonds between multiple layers of paint and between the paint and the substrate. See also “Enclosure.”
Encapsulation. A specified procedure necessary to coat ACMs or asbestos contaminated surfaces with an encapsulant to control the possible release of asbestos fibers into the ambient air.
Encapsulation. Encapsulations are the second alternative that will be tested at the validation site as benchmark to the spiral coil heat exchanger; here both technical performance comparison and economic evaluation will be conducted. However, the special encapsulation designs proposed in the previous H2020 PUMP-HEAT Deliverable D3.4 require specific manufacturing and production procedures as no currently commercially available product is available. Hence, two solutions were at our disposition: 3-D printing of the exact design geometry or procurement of commercially available capsules similar to the proposed design dimensions. 3D printing can prove to be a time-consuming process and the material compatibility of PCM as well as the softening of the printing material. For example, Polylactic Acid (PLA), may be a concern without long term testing if no other printing material is to be used. On the other hand, commercially available products with designs similar to the ones proposed such as the HeatStixx and HeatSel (Axiotherm, 2019) have been selected, see Figure 3-5. Design parameters of the HeatStixx and HeatSel are given in Table 3-1. 7 The blue prints of coil in Appendix 1. Figure 3-5 Macro-Encapsulations from Axiotherm Table 3-1 Parameters of Macro-Encapsulations Parameters HeatStixx HeatSel Dimensions Ø 42 x 310 mm 185 x 185 x 32 mm Number of Encapsulations per 100L Approx. 150 Approx. 110 Cycle Stability >10,000 cycles >10,000 cycles Volume Expansion due to phase change Approx. 5 % Approx. 5 % These Axiotherm macro-encapsulations have been proven to work efficiently within the working temperature range that suits the operating condition of the H2020 PUMP-HEAT Project (Axiotherm, 2019). Furthermore, the design enables the entire encapsulated PCMs to be involved in the phase change process. This commercial product is to be tested on the lab validation site.
Encapsulation. Application of an encapsulant to asbestos-containing building materials to control the possible release of asbestos fibers into the ambient air.
