Heat-storage capacities

Normally, the heat storage capacity of the air in the space can be neglected. Machines, tools, equipment, etc. situated in the room may have a significant influence on the thermal behavior of the room and must be considered in the simulation. 

Perhaps a more severe comparison of model response is the time history of the centerline temperature. These values reflect the interaction of several phenomena the reaction itself, the heat liberated by the reaction, the heat storage capacity of the material, and the rate at which heat can be carried away from the centerline region by conduction. Figure 8 shows the temperatures predicted by the Chiao and finite element models, as well as the imposed autoclave temperature history. It also includes five thermocouple readings which were reported in Chiao s manuscript (8). 

The atmosphere itself also has a huge heat storage capacity. In this case, part of the thermal energy is stored in the heating of air, i.e., global warming. Subsequent increase in evaporation means that additional energy is stored in the atmosphere. 

It was concluded that the storage block is the most promising application. A prototype with approx. 4.1 kWh latent heat storage capacity was then built and is currently operated at Grammar. The storage (Figure 177) is charged via a 20 m2 collector with an air flow of 180-300 m3/h. 

The technical suitability of insulation materials is described by a series of technical parameters relating to the material (heat conductivity and heat storage capacities, damp protection, fire protection class, noise-insulating effect, properties related to building biology, e g. content of hazardous substances such as flame retardants and insecticides). Mineral wools have certain advantages over other insu-... 

Corrections of the surface roughness for urban areas and urban heat fluxes (adding the anthropogenic heat flux, heat storage capacity and albedo change). This can be complemented with an analytical model for wind velocity and diffusivity profiles inside the urban canopy (Zilitinkevich and Baklanov, 2005 [671] Baklanov et al., 2005 [38]). 

Heat Storage Capacity - The amount of heat that a material can absorb and store. 

The specific entropy capacity plays an important role for the heat storage capacity of a material. Therefore, it has for example consequences for the behavior of construction materials during heating such as wood in case of fire.

In addition to ice (water), more than 500 natural and synthetic PCMs are known. These materials differ one from another in terms of their phase change temperature range and their heat-storage capacities. 

A comparison between organic and salt-based PCMs is provided in Table 7.3. Today, most popular PCMs used in textile applications are based on paraffins (waxes). Compared to other PCMs, paraffins have high heat-storage capacities. 

Heat storage capacity should be large so that frequent changeovers are not required. 

The primary circuit is a pool type, and the reactor vessel has a large heat storage capacity, which guarantees that operators have sufficient time to analyze accident conditions and take necessary mitigation steps under relevant transition and accident conditions.
