With the goal of achieving carbon-neutral, Zero Energy Building is drawing attention and use radiant air-conditioning systems on rise. In this study, actual condition thermal environment formed in office under operation TABS floor blow system adopted nZEB Kanazawa City was investigated. addition, sensation questionnaire for workers conducted summer. As a result analysis, PMV value by zone respo...

In this paper, we present what was learned in the research & design process of a decentralized ventilation system with chilled ceilings for a commercial office in Singapore. We make two key observations from the knowledge gathered. First, we observe, in quantitative terms, that present-day radiant cooling panel products may not provide sufficient sensible cooling capacity for commercial offices...

Radiant heating/cooling systems are thermally efficient and economically feasible alternatives to conventional ventilated air conditioning. This study experimentally investigates the thermal performance of ceiling radiant cooling panel (CRCP) with a segmented concave surface by evaluating conditions inside laboratory-scale room equipped this new panel. The experiments were carried out under var...

The detailed mathematical model of heat and mass transfer of steel ingot of curvilinear continuous casting machine is proposed. The process of heat and mass transfer is described by nonlinear partial differential equations of parabolic type. Position of phase boundary is determined by Stefan conditions. The temperature of cooling water in mould channel is described by a special balance equation...

The existing radiant cooling systems have the drawback of low energy efficiency due to its secondary heat exchange via chilled water. To overcome this dilemma, a novel refrigerant-cooling terminal (RCRT) system utilizing refrigerant as direct medium is proposed. A detailed numerical model established describe transfer characteristics and validated with experimental data. influences operating pa...
