Summary Refrigerants bearing high global warming potential (GWP) and ozone depletion potential (ODP) were outlawed or facing time‐beared permission under the Montreal (1987), Kyoto (1997) protocols, F‐Gas law (2015), Paris Accord (2016), and recent Kigali Amendment to Montreal Protocol (2019). In order to modify followed by the paradigm shift of existing heating and cooling systems, American Society of Heating, Refrigeration, and Air‐Conditioning Engineers (ASHRAE) envisaged natural and synthetic refrigerants (Synrefs) are under investigation globally. Carbon dioxide (CO2) is a popular natural refrigerant (Natref) replacing Synrefs used in commercial heating, ventilation, air conditioning, and refrigeration (HVAC&R) systems globally. A rampant rise is observed in markets of Asia (Japan and China), North America (the United States and Canada), the Australian continent, and Africa (South Africa) by reaching 20 000 CO2‐stores around the globe. The European markets are leading the utilization of CO2 in the heat pump, and refrigeration, CO2 based markets estimate 14% of the total food retail stores (400 m2). Japan is the second leading market of CO2 heat pump and refrigeration with more than 10 200 CO2 condensing units. CO2 transcritical systems have a share of more than 10% in only European market (large stores); however, their share is less than 10% of total stores in other major markets of the world. New pump and compressor‐driven transcritical CO2 systems integrate ejectors, condensers, and booster systems to reduce energy consumptions, enhance efficiency, efficacy, and coefficient of performance. This article reports a critical review of the CO2 based heating, cooling, and refrigeration system and presents updated literature along with barriers and challenges on commercial use of Natref‐based heating and cooling applications worldwide.

“…The vapor evaporated at low pressures is absorbed by the high-concentration LiBr aqueous solution in the lower portion of the absorber through position (20) and (21). The LiBr aqueous solution, which absorbs the refrigerant vapor, is transferred to the generator by the solution pump (positions (11), (12) and (13)), and the high-concentration LiBr aqueous solution remaining in the generator is transferred to the absorber by the height difference (positions (14), (15) and (16)).…”

Recently, extensive studies on power generation using clean energy have been conducted to reduce air pollution and global warming. In particular, as existing internal combustion engines lose favor to power generation through hydrogen fuel cells, the development of tri-generation technology using efficient and reliable fuel cells is gaining importance. This study proposes a tri-generation thermal management model that enables thermal control and waste heat utilization control of a high-temperature PEMFC stack that simultaneously satisfies combined cooling, heating, and power (CCHP) load. As the high-temperature PEMFC stack operates at 150 °C or more, a tri-generative system using such a stack requires a thermal management system that can maintain the operating temperature of the stack and utilize the stack waste heat. Thus, to apply the waste heat produced through the stack to heating (hot water) and absorption cooling, proper distribution control of the thermal management fluid (cooling fluid) of the stack is essential. For the thermal management fluid control design, system analysis modeling was performed to selectively design the heat exchange amount of each part utilizing the stack waste heat. In addition, a thermal management system based on thermal storage was constructed for complementary waste heat utilization and active stack cooling control. Through a coupled analysis of the stack thermal management model and the absorption cooling system model, this study compared changes in system performance by cooling cycle operation conditions. This study investigated into the appropriate operating conditions for cooling operation in a tri-generative system using a high-temperature PEMFC stack.

The calculation of heating and cooling loads to office buildings is different due to the presence of many people and also their activity at certain times of the day. In this research, a model office building is first simulated in Semnan, Iran using Design Builder software. After applying the necessary assumptions about the presence of people and building activation time, the heating and cooling loads of the base sample building are calculated with the specified envelope configuration. In the next step, some changes are applied to the thermal insulation of the envelope and the roof as well as the configuration of the windows. Then, for obtained heating and cooling loads for each case, hybrid solar‐assisted cooling heating and power (CCHP) system are designed. Thus, for different envelope configurations, the best case for the capacity of the power generation unit (PGU), the ratio of PGU‐generated energy to solar energy, and fuel consumption saving of the solar‐assisted CCHP system is determined. Results show that the use of appropriate window configuration and the suitable insulation of the walls and roof can save 24.8% of PGU capacity and 53.48% of fuel consumption in the solar‐assisted CCHP system.
