Abstract: La divulgation concerne un système d'eau chaude au gaz et un procédé de commande associé. Le système d'eau chaude au gaz comprend : un dispositif de combustion ; un dispositif d'échange de chaleur principal disposé d'un côté du dispositif de combustion, de sorte que le dispositif d'échange de chaleur principal puisse effectuer un échange de chaleur avec le dispositif de combustion ; un tuyau de retour de liquide principal relié à une extrémité d'entrée de liquide du dispositif d'échange de chaleur principal ; un tuyau de sortie de liquide principal relié à une extrémité de sortie de liquide du dispositif d'échange de chaleur principal ; et une structure d'accouplement permettant de relier le tuyau de retour de liquide principal et le tuyau de sortie de liquide principal, de sorte qu'une partie d'un liquide dans l'un des tuyaux, parmi le tuyau de retour de liquide principal et le tuyau de sortie de liquide principal, puisse couler vers l'autre tuyau au moyen de la structure d'accouplement. Selon le système d'eau chaude au gaz, la structure d'accouplement utilise un liquide dans le tuyau de retour de liquide principal pour modifier une différence de température entre le liquide dans le dispositif d'échange de chaleur principal et le liquide coulant hors d'une extrémité de sortie du tuyau de sortie de liquide principal, de sorte que le liquide dans le dispositif d'échange de chaleur principal maintienne une haute température, et que le gaz de combustion effectuant un échange de chaleur avec le dispositif d'échange de chaleur principal soit également maintenu à une haute température et soit moins susceptible de se condenser ; ainsi, l'efficacité thermique du système d'eau chaude au gaz est améliorée et la corrosion du dispositif d'échange de chaleur principal, due à la condensation du gaz de combustion, est empêchée.

Abstract: For SL resource allocation, the Rx UE assisted resource allocation mechanism can be applied to improve the reliability and reduce the overall latency for SL communication, which can work independently or jointly with Tx UE based sensing and resource allocation mechanism. Rx UE can be triggered to send the feedback information upon reception of the SCI and/or data from the Tx UE. The feedback information can carry Rx UE's resource sensing information, CSI info, observed Doppler/delay/moving speed related information and MIMO related feedback information to assist the resource/MCS/MIMO/DMRS pattern selection at Tx UE. It is desirable for Rx UE to feedback such assistance information (just) before the reserved resources by Tx UE to be transmitted. So the Tx UE can take into account the feedback information to assist resource re-selection and/or resource utilization.
