Abstract
Succeeding comfort conditions in hot climates region with minimum power consumption is the important requisite in designing the air conditioning system such as split unit air conditioning (SUAC). Under Iraqi conditions, the current study compared the energy consumption of SUAC in two classrooms at Southern Technical University/Engineering Technical College-Basra (STU/TCB). Additionally, this paper developed an autonomous cooperative controller for sensing changes in dynamic space load and auto-response of a variable speed compressor over 12 hours. The first classroom has a single-speed SUAC compressor, while the second classroom has a variable-speed SUAC compressor with a total capacity of 6 Ton. The results show that in June, the largest amount of energy saved was 51.5 % at 7 AM, while the least amount of energy saved was 10.9 % at 2 PM. SUAC with the autonomous controller was discovered to be the highest control unit with less energy utilized than other SUACs, achieving a value of 24.8 % energy savings. The split unit control (SUC) could result in a significant reduction in SUAC compressor power in class 2 at seasonal energy efficiency rating (SEER) levels 8 or 20, resulting in a 75% reduction in operating costs throughout the year.
