Numerical and Experimental study of a new building cooling system based on compression refrigeration cycle

Today, various cooling systems such as evaporative cooler, split, air conditioner etc., are used to cool the building, which have a number of advantages and disadvantages. One of the most important disadvantages that can be mentioned for many cooling systems is the non-uniform temperature distribution in the building zones. The most important part of the building's heat loss is through the windows. Accordingly, in this research, a new cooling system based on compression refrigeration cycle is proposed and examined numerically and experimentally. Experimental evaluation of this system was performed in the air conditioning workshop and its numerical evaluation was performed in Design Builder software. In addition this system was compared with split cooling system. Among the most important results obtained from this research, we can point out the uniform distribution of the indoor air temperature and the reduction of energy consumption compared to the convectional cooling systems. When using a window coil system, the difference between the maximum and minimum temperature in a large part of the room was less than 1 degree Celsius. In the split system, however, the temperature has changed by about 2 degrees Celsius by moving from the ceiling of the room to the floor. Moreover, energy consumption of the system was 6.7% lower than that of split cooling system.
