An improved optimization adjustment strategy for building heating ventilation and air conditioning (Heating Ventilation Air Conditioning, HVAC) is proposed. The energy consumption model of heating/refrigeration established by using the instantaneous balance heat, then optimal operation HVAC based on weather forecast data constructed in range user temperature comfort. Finally, MATLAB TRNSYS simu...

This article presents the principle of operation an experimental indirect evaporative cooling system which applies liquid desiccant solution as a drying agent. mobile is going to be built for investigation effects different working parameters (e.g. regenerating temperature salt-solution, air flow rates, droplet size and mixing path length, etc.) on produced cooled dehumidified air, well initial...

Energy efficient systems are the most desirable systems. Due to huge rise in energy prices and lack of availability of energy, the effective use of energy has become the need of time. Energy recovery both in heating systems as well as in air-conditioning systems saves a lot of energy. In this paper energy recovery system has been designed and optimized for central air-conditioning systems for v...

This paper proposes a new approach of cooling system for home. The main advantages of this cooling system are it consumes very low power, no emission of harmful gas and support for health. The basic principle of the system is free cooling is taking place when the external ambient air entropy is less than the indoor air enthalpy and the cool external air is transferred to the building room direc...
