“…A case study conducted by Togawa et al [6] indicates that waste heat provides more environmental benefits than the individual boiler system. By using waste heat from glass melting furnaces, gas turbine exhaust, steam boiler exhaust, etc., fuel oil consumption is reduced by 16.05 TJ/year, while total CO 2 emissions are reduced by 1204 ton/year, in the investigated waste heat system.…”

Abstract:Various energy sources can be used for room heating, among which waste heat utilization has significantly improved in recent years. However, the majority of applicable waste heat resources are high-grade or stable thermal energy, while the low-grade or unstable waste heat resources, especially low-temperature industrial residual water (IRW), are insufficiently used. A thermal energy storage (TES) unit with paraffin wax as a phase change material (PCM) is designed to solve this problem in a pharmaceutical plant. The mathematical models are developed to simulate the heat storage and release processes of the TES unit. The crucial parameters in the recurrence formulae are determined: the phase change temperature range of the paraffin wax used is 47 to 56 • C, and the latent heat is 171.4 kJ/kg. Several thermal behaviors, such as the changes of melting radius, solidification radius, and fluid temperature, are simulated. In addition, the amount of heat transferred, the heat transfer rate, and the heat storage efficiency are discussed. It is presented that the medicine production unit could save 10.25% of energy consumption in the investigated application.

“…Studies on thermal energy storage systems that combine phase change materials (PCMs) with building structures have been actively conducted to reduce the heating energy consumption in buildings [1]. In particular, studies have been continuously conducted on PCM radiant floor heating systems, which can decrease heating energy by improving the energy performance of existing radiant floor heating systems [2][3][4][5][6][7][8][9][10][11].…”

A phase change material (PCM) is an energy storage mass with high heat storage performance. In buildings, PCMs can be utilized to save energy in radiant floor heating systems. This study aims to analyze the thermal performance and energy saving potential by the PCM radiant floor heating system based on wet construction method and hot water. For such analysis, EnergyPlus program was used. As for the results, it was found that the proposed system almost maintained the set point of indoor air and a floor surface. Moreover, when a 10 mm PCM was applied, it was possible to save 2.4% of heating energy annually compared to existing buildings. In particular, when a 20–50 mm PCM was applied, it was found that 7.3–15.3% of heating energy was reduced annually. If indoor air temperature exceeds the comfort range of the proposed system, this problem can be solved by adjusting the set point of the floor surface or by increasing the temperature of hot water.

“…Phase change material (PCM) has been widely integrated in building envelopes [1][2][3][4][5], thanks to its ability of increasing the thermal inertia performance of building components [6][7][8][9], hence improving indoor thermal comfort [10][11][12][13][14]. In the past several decades, many studies have been carried out to explore the effectiveness of PCM on improving indoor thermal comfort in buildings [15][16][17][18].…”
