This research work aims to investigate and subsequently optimize the operating parameters that affect thermal comfort indoor air quality in school environment. The proposed design uses a coupling between solar ventilation absorption chiller-air conditioning. heating tower of an adsorption chiller connected conditioning system can be driven by waste heat from (exhausted hot air) thank this linka...

Adsorption chillers can avoid two types of greenhouse gas emissions from conventional cooling technologies: energy-related by utilizing waste heat and refrigerant leakage-related employing the natural water. However, water restricts minimal temperature to its freezing point. To overcome this limitation, herein, a boiling antifreeze in adsorption is proposed. For purpose, databank over 12 000 mo...

Previous studies have been conducted by employing various methods to reduce the condenser water temperature, a crucial control variable consider when attempting improve operational efficiency of chiller. The existing literature dealing with effects low-condenser temperatures is limited, as cooling flow rate often considered operating loop. However, produce additional low temperatures, approach ...

In this study, cold and thermal storage systems were designed manufactured to operate in combination with the water chiller air-conditioning system of 105.5 kW capacity, aim reducing operating costs maximizing energy efficiency. The tank used a mixture 10 wt.% glycerin as phase-change material (PCM), while was heat transfer fluid (HTF). exchanger made polyvinyl chloride (PVC). On other hand, ca...

The dairy industry uses a number of energy intensive thermal processes like cooling, heating and cleaning that require electrical energy. Those use temperatures between 4 °C 200 could be potentially powered using solar but one the main challenges is complexity selection integration components used for system such as collectors, cooling equipment. with temperature requirements 300 400 are mainly...

In the present study, exhaust gases from Tehran refinery crude oil furnace are used in a Heat Recovery Steam Generator (HRSG)for generating steam. Then, the steam is directed to a double effect absorption refrigeration cycle to produce cooling. To meet the object, mass and energy balance equations of the coupling is carried out for both the HRSG and the absorption chiller and unknown thermodyna...
