文摘Heating,Ventilation,andAir Conditioning(HVAC)systems are critical formaintaining thermal comfort in office environments which also crucial for occupant well-being and productivity.This study investigates the impact of integrating ceiling fans with higher air conditioning setpoints on thermal comfort and energy efficiency in office environments.Field measurements and questionnaire surveys were conducted to evaluate thermal comfort and energysaving potential under varying conditions.Results show that increasing the AC setpoint from 25○C to 27○C,combined with ceiling fan operation,reduced power consumption by 10%,achieving significant energy savings.Survey data confirmed that 85%of participants reported consistent thermal sensations across all conditions,with ceiling fans effectively compensating for higher setpoints through enhanced air circulation.CFDsimulations revealed that mediumspeed ceiling fan operation produced the most uniformairflowdistribution,with an average air velocity of 0.45 m/s,and minimized temperature variations,ensuring balanced thermal conditions.Temperature analysis showed a reduction in hotspots and cold zones,maintaining an average temperature deviation of less than±0.5○C.Predicted Mean Vote(PMV)evaluations at a 27○C setpoint indicated improved thermal comfort,with average PMV values around−0.3,corresponding to a“neutral”thermal sensation.These findings demonstrate the effectiveness of integrating ceiling fans with HVAC systems in achieving energy efficiency and occupant comfort,offering a sustainable approach to reducing AC energy consumption in office environments.

文摘Under the“dual carbon”goals,this paper constructs an optimization model of the comprehensive energy system in the park.A stepwise carbon excess rate mechanism and an electric vehicle coupling strategy are proposed:A carbon quota trading system is established based on the baseline method,and the stepwise function is adopted to quantify the cost of excess carbon emissions;Introduce the price demand response and the two-way interaction mechanism of electric Vehicle vehicle-to-grid(V2G)to enhance the flexible regulation ability.Aiming at the uncertainty of wind and solar output,a typical scene set is generated by combining Latin hypercube sampling with the scene reduction method.The goal is to minimize the operating cost and maximize the consumption of renewable energy,and it is solved through the CPLEX solver in the MATLAB platform.Through simulation verification of the proposed models and methods in various scenarios,the simulation results show that under the coupling of the carbon excess rate trading mechanism,the demand response mechanism,and the vehicle-to-grid interaction of electric vehicles,the total daily operating cost of the system decreases by 25.3%,reduce the dual pressure of energy consumption costs and the economic environment,and achieve the coordinated optimization of economic and ecological benefits.
文摘Objective:To evaluate the clinical effect of comfort nursing intervention in preventing incontinent-associated dermatitis(IAD)and related complications in critically ill patients.Methods:This study enrolled critically ill patients from the Intensive Care Unit at Ningxiang People’s Hospital between June 2020 and June 2024.Patients were randomly assigned to a comfort nursing group(n=51)and a routine nursing group(n=53).The comfort nursing group received comprehensive comfort nursing,while the routine nursing group received standard care.The incidence,classification and area of IAD as well as the incidence of complications and patient/family satisfaction with nursing care,were assessed.Results:The incidence of IAD was significantly lower in the comfort nursing group(8 patients)compared to the routine nursing group(21 patients)(P<0.05).Additionally,the incidences of wound infection and muscle soreness were notably lower in the comfort nursing group(both P<0.05).Patient and family satisfaction in the comfort nursing group was significantly higher than in the routine nursing group(both P<0.05).Conclusion:Comfort nursing intervention is effective in preventing IAD and reducing associated complications in critically ill patients,thereby improving patient and family satisfaction with treatment.
