Solution Overview
Problem
The use of latent heat storage materials in rotary fittings leads to deterioration due to precipitate generation from repeated solidification and melting, which reduces the heat storage capacity.
Innovation Solution
Incorporating a cell array plate material with a rotation mechanism that allows at least half rotation in the vertical direction to break down precipitates, thereby maintaining heat storage efficiency.

1Quantity of substance
If latent heat storage material is used for heat storage layer, then heat storage capacity is improved, but precipitate generation causes deterioration in heat storage amount
Solution Approach 1:
The rotary fitting enables dynamic rotation of the heat storage layer between indoor and outdoor sides. This dynamic positioning allows the system to utilize the latent heat storage material's phase change properties for heat storage while periodically exposing it to external conditions that prevent precipitate accumulation, thereby maintaining long-term heat storage capacity.
Solution Approach 2:
The system implements periodic rotation between storing heat (when heat storage layer faces indoor side) and recovering/preventing precipitate (when heat storage layer faces outdoor side). This periodic action between heat storage mode and precipitate prevention mode ensures sustained reliability of the latent heat storage material over time.
2Temperature
If heat storage layer is directed to indoor side for heat discharge, then indoor temperature control is improved, but radiation cooling from indoor side occurs
Solution Approach 1:
The rotary fitting dynamically switches the heat storage layer's orientation based on operational requirements. When indoor heating is needed, the heat storage layer rotates to face the indoor side for heat discharge. When outdoor cooling is desired or to prevent radiation losses, it rotates to face the outdoor side, providing adaptive temperature control.
Solution Approach 2:
The system employs periodic rotation to alternate between heat discharge mode (facing indoor side for temperature control) and heat recovery/protection mode (facing outdoor side to prevent radiation cooling losses). This periodic switching optimizes both indoor temperature control and energy conservation.

AI summary
A pivot window includes a laminated body. The laminated body includes two sheets of a plate material; a peripheral end member provided at a peripheral end parts of the two sheets of the plate material; and a cell array plate material which is interposed between the two sheets of the plate material and which has a plurality of cells respectively having a gas phase and encapsulating a latent heat storage material having a melting point and a freezing point in a specific temperature range. The pivot window further includes a rotation mechanism for causing the laminated body to perform at least half rotation in a vertical direction.
