“…Fig. 12 compares the EERs of the proposed system with a split air-conditioner from an existing study [31], the results show that the energy efficiency ratio of the RCRT cooling system is superior to the split air-conditioner. It is attributed to the RCRT cooling system with higher evaporating temperature and no fan energy consumption.…”

Split air conditioner (SAC) plays a critical role for temperature control of buildings. In recent years, the manufacturing process of SAC tends to consider energy-saving and environmental protection factors to reduce air pollution and alleviate energy crisis. However, the design of environmental-friendly SAC will increase the manufacturing cost, thereby increasing the burden on airconditioning companies. Therefore, the eco-cost analysis of SAC is of great significance for air conditioner manufacturers. To this end, a new SAC eco-cost assessment method based on activity based costing method is innovatively proposed in this paper. In this method, a K-nearest neighbor algorithm is used to deal with the missing data in SAC samples. An environmental and non-environmental cost assessment approach is developed based on the activity-based costing method to estimate the eco-cost of SAC over its whole life cycle. In addition, the impact of energy efficiency deviation on SAC eco-cost is numerically analyzed. Finally, the proposed ecocost assessment method is programmed on a Gabi software, and validated using real SAC data from a Chinese airconditioning company. Simulation results show that the proposed method can provide an estimate of the eco-cost of SAC, thus helping airconditioning companies to improve their competitiveness in the future where energy-saving and emission reduction are increasingly important.

“…The result showed that the fuzzy controller control can save 8.92% energy compared with traditional ON/OFF methods. Chen et al [14] studied the effect of an energy-saving device (ESD) on the performance of a split-type air conditioner and the proposed low-cost approach design for decreasing the shell temperature and power consumption of a compressor. The ESD was fabricated using a moisture-transferring and quick-drying textile and then coated on the shell surface of the compressor to absorb the condensate expelled by a condensate pipeline and distributor to enable evaporative cooling of the compressor.…”

Recently, energy saving has been a major issue in all aspects. In buildings, air conditioning is one major part of power consumption. In this study, we examined the effect of an intermittent control strategy for air conditioning on energy saving in western-exposed rooms under subtropical weather conditions. The strategy applied periodic deactivation and reactivation to the air conditioners. Room temperatures, power consumption, and readings from sensors of air conditioners of two identical rooms were monitored and analyzed. For indoor temperatures, we found that the deactivation of the air conditioner for 15 min resulted in temperature peaks that were 4 to 5 °C higher than the control room. The reactivation of the air conditioner was able to cool down the room within 10 min based on the built-in sensor. However, due to the location and resolution of the sensor, the overall temperature from the four temperature and humidity sensors was still higher than the target setting, which may cause thermal discomfort. For power consumption, the strategy led to power peaks while reactivating, but the summation was 2.9% lower.
