Lchair. This structure adjustments, allowing multiple positions for typical postural to become adopted. The sitting position and also the decubitus position. The entire mechanism uses an electromechanical linear actuator controlled by a PID handle. The controllers’ design and style consisted of calculating the variables in the PID controller.Author Contributions: Conceptualization, C.R.T.-S. and J.I.S.-C.; methodology, C.R.T.-S.; computer software, L.A.A.-P.; validation L.A.A.-P., J.C.P.-R. along with a.O.-O.; formal evaluation, J.I.S.-C.; investigation, J.I.S.-C.; sources, J.A.L.-N.; information curation, J.A.L.-N.; writing–original draft preparation, L.A.A.-P.; writing– critique and editing, C.R.T.-S.; visualization, J.C.P.-R.; supervision, A.O.-O.; FM4-64 Description project administration, C.R.T.-S.; funding acquisition, C.R.T.-S.

Heat Balance Calculation and Power Efficiency Evaluation for Creating Clusters Based on Psychrometric Chart. Sensors 2021, 21, 7606. https://doi.org/10.3390/ s21227606 Academic Editor: Do Hyoung Shin Received: 28 October 2021 Accepted: 12 November 2021 Published: 16 NovemberAbstract: Ways to execute precise calculation of heat balance and quantitative analysis of energy efficiency for developing clusters is definitely an urgent difficulty to be solved to PF-05105679 medchemexpress minimize creating power consumption and strengthen energy utilization efficiency. This article proposes a strategy for the heat balance calculation and power efficiency evaluation of developing clusters depending on enthalpy and humidity diagrams and applies it for the energy management of creating clusters containing major return air systems and heating pipe networks. Firstly, the basic structure and power management principle of building clusters with a primary return air system in addition to a heating pipe network have been provided, as well as the heat balance calculation and power efficiency evaluation method based on i-d diagram was proposed to realize the accurate calculation of heat load as well as the quantification of power utilization. Secondly, the power management model in the building cluster with a major return air s.
