An air-conditioning system (ACS), which consumes large amounts of high-grade energy, is essential for maintaining the indoor thermal environment of modern buildings. However, an ACS consumes almost half of the total energy of the building. Therefore, it is necessary to reduce the energy consumption of the ACS to promote energy conservation and emission reduction in the building sector. In fact, there is an abundance of waste heat and low-grade energies with the potential to be utilized in ACS in nature, but many of them are not utilized efficiently or cannot be utilized at all due to the low efficiency of thermal energy conversion. Known as a passive thermal transfer device, the application of a heat pipe (HP) in the ACS has shown explosive growth in recent years. HPs have been demonstrated to be an effective method for reducing building cooling and heating demands and energy consumption in ACS with experimental and simulation methods. This paper summarizes the different HP types applied in the ACS and provides brief insight into the performance enhancement of the ACS integrated with HP. Four types of HPs, namely tubular HP (THP), loop HP (LHP), pulsating HP (PHP) and flat HP (FHP), are presented. Their working principles and scope of applications are reviewed. Then, HPs used in natural cooling system, split air conditioner (SAC), centralized ACS (CACS) and cooling terminal devices are comprehensively reviewed. Finally, the heat transfer characteristics and energy savings of the above systems are critically analyzed. The results show that the performance of the HP is greatly affected by its own structure, working fluid and external environmental conditions. The energy saving of ACS coupled with HP is 3–40.9%. The payback period of this system ranges from 1.9–10 years. It demonstrates that the HP plays a significant role in reducing ACS energy consumption and improving indoor thermal comfort.

“…Heating, ventilation, and air conditioning systems is used to maintain thermal comfort and air quality in the building or vehicle. But the energy required to operate an HVAC system is enormous, so sustainable improvement is needed to increase energy efficiency [5][6][7][8][9]. In the case of electric vehicles with lower energy availability, the use of air conditioning can consume a large portion of the total energy consumption of the car [10].…”

Vehicles parked under the direct sun cause an increase in the cabin temperature drastically. The extreme increase in vehicles cabin temperature will increase air conditioning (AC) energy and fuel consumption, can damage interior equipment, and increases the health risk to passengers in the car. Therefore, this research aims to investigate the thermoelectric as a cooling system for a parked car integrated with solar energy. The solar panel on the car roof generates electricity as a cooling system energy source. The cooling system consists of 4 thermoelectric coolers equipped with heatsinks and axial fans on the hot and cold side of thermoelectric. The test was conducted on passenger cars during the day for 4 hours of parking. The result shows that the cabin car temperature decrease by 6,1°C or 13% compared to without cooling, which will increase passenger comfort and reduce energy consumption.
