Comprehensive RC heat transfer model of floor radiation energy supply system based on building design parameters

Abstract

The invention discloses a comprehensive RC heat transfer model of a floor radiation energy supply system based on building design parameters. The comprehensive RC heat transfer model is formed by coupling a cooling component RC simplified model, an unstable-state RC heat transfer model of a multi-layer wall body and a room comprehensive heat transfer RC network model. The cooling component RC simplified model is formed by coupling a pi-type RC network heat transfer model between a water supply pipe and a core temperature layer and a multi-layer wall RC finite difference model between the core temperature layer and the upper and lower surfaces of a cooling component; wherein the unstable-state RC heat transfer model of the multilayer wall body comprises a south wall model, an east wall model, a ceiling model, a west wall model and a north wall model; a room comprehensive heat transfer RC network model; wherein a group of radiation surface thermal resistance and convection heat exchange thermal resistance which are connected in series are respectively arranged between the space core temperature point and the multilayer wall RC finite difference model, the south wall model, the east wall model, the ceiling model, the west wall model and the north wall model, and a radiation space thermal resistance is connected between any two radiation surface thermal resistances.

Description

technical field [0001] The invention relates to the field of floor radiation air-conditioning systems, and more specifically relates to a comprehensive RC heat transfer model of a floor radiation energy supply system based on architectural design parameters. Background technique [0002] In recent years, with the rise of temperature, the energy consumption of air conditioners occupies most of the energy consumption of buildings, and the task of energy saving is urgent. Moreover, the traditional air-conditioning system is prone to cause sub-health diseases such as sick building syndrome, and it is also easy to cause the spread of bacteria and diseases. With the rise of radiant cooling technology, it makes up for the shortcomings of traditional air-conditioning systems, and radiant air-conditioning systems have the advantages of comfort and hygiene, and have great application development. The floor radiant air-conditioning system is to embed fluid pipes in the building, in or...
