District heating and cooling systems can repurpose excess heat into hot water and supply it to buildings through their network of insulated, underground pipes. Paired with heat pumps, these systems can deliver clean heating and cooling to millions of households, offering a more energy-efficient and sustainable alternative to fossil fuel heating.
Waste heat from air conditioning can be reduced through the use of passive cooling building design and zero-energy methods like evaporative cooling and passive daytime radiative cooling, the latter of which sends waste heat directly to outer space through the infrared window.
Waste of the by-product heat is reduced if a cogeneration system is used, also known as a Combined Heat and Power (CHP) system. Limitations to the use of by-product heat arise primarily from the engineering cost/efficiency challenges in effectively exploiting small temperature differences to generate other forms of energy.
The results indicate that OHP can recover up to 240 W of heat from the waste exhaust air stream, with a low-pressure drop of almost 62 Pa in the cold air stream. The heat transfer rate with 70% n-pentane is two times that of the evacuated OHP.
Throughout the findings, the results have shown that it is worthwhile implementing the energy recovery system (ERS) in HVAC. As the ERSs could save a considerable amount of wasted energy, such an update has proven its effectiveness and efficiency through several studies.
The thermodynamics of the ORC is highly feasible for the recovery of low-temperature waste heat to generate kinetic energy. A novel refrigeration cycle, based on the integration of ORC into the conventional AC cycle, maximises the overall energy efficiency of the system.
