- Abstract
The Solar House "Twist Box" is a project of the Belgrade University, run by the Faculty of Architecture; School of Electrical Engineering; Faculty of Technology and Metallurgy and Faculty of Mechanical Engineering. This project has been launched for the purpose of the "Solar Decathlon Middle East" competition and is now in the final stage in which the documentation for carrying out the works is being prepared. Here we will be talking about the HVAC equipment that will be designed for this building, the way they are selected and solutions that are developed in order to reduce heat load. The first problem we encounter is location and climatic conditions. The location where this house will be built in November 2018 is 30km from Dubai UAE. Climatic conditions at this location are very unfavorable from the standpoint of air conditioning because they represent a combination of very high temperatures and intense solar radiation. In order to achieve comfort conditions inside the building, it is necessary to provide the required amount of fresh air of the appropriate temperature. In order to select an adequate system, it was first necessary to calculate the heat load based on climatic influences, thearchitectural and construction model, the number of people envisaged to be in premises, electrical installations and other factors. In addition to the calculated heat flow, a simulation was performed that showed a more realistic picture throughout the year. After calculating the heat load, equipment is selected for covering the total heat load, which ensures the design temperature in the room and provides the required amount of fresh air. The preparation of air-conditioned air is carried out using a heat recovery, and high-static ducted indoor units. The heat recovery serves to cool the fresh outside air at the expense of heating the waste air from the room. The high-static ducted indoor unitsare supplied with the refrigerant from the outdoor unit. Prepared air is supplied to the living space by means of supply air equipment which has been selected so that it fits best into the interior, while ensuring sufficient levels of noise and, more importantly, to provide an adequate air flow inside the space. The second task is the preparation of domestic hot water, which is done by solar energy receiver. Space is allocated on the roof for the solar energy receiver, and it is connected with the hot water boiler inside the house.
