Energy performance prediction of thermoelectric ceiling radiant panels with a dedicated outdoor air system | 2017 | English | 9 pp
This paper proposes a dedicated outdoor air system (DOAS) with thermoelectric module radiant cooling panels (TEM-RCP). The DOAS involves the concept of a decoupled system with a parallel sensible cooling unit.
Evaluation of thermal comfort in an office building served by a liquid desiccant-assisted evaporative cooling air conditioning system | 2017 | English | 10 pp
Recent studies examined a liquid desiccant indirect and direct evaporative cooling assisted 100% outdoor air system (LD-IDECOAS) as an energy conserving alternative to conventional air conditioning systems.
Preventing condensation and frosting in an energy recovery ventilator using a preheat coil | 2017 | English | 9 pp
One of the problems presented by energy recovery ventilators (ERV) is the condensation/frosting problem that occurs during winter time. In order to prevent this problem, preheating outdoor air is the most common method used nowadays.
Evaluating natural ventilation cooling potentials during early building designs | 2017 | English | 9 pp
Natural ventilation (NV) is an efficient way of cooling buildings, and its energy saving potentials however depend on many parameters including local hourly weather and climate conditions, types of ventilations, indoor cooling loads (or heat gains
