Then a new device was designed and built, which could make constant temperature hot water and adjust the temperature automatically. The design of its electrical control system was also introduced.

设计建造了一套自动制取恒温水、自动调节水温的装置，并对其电气控制系统进行了设计。

Dynamic models of a hot water heating system and an electrical heating system were developed for a standard room and utilized to simulate and analyze the responses of the two types of heating systems.

针对标准房间建立热水和电采暖系统动态模型，模拟和分析这两种系统动态响应。
