Even though the control device of the heating system works well, insufficient water flow rates can degrade control performance and thermal comfort.

即使供热系统的控制装置运行良好，水的流速不足也能够降低控制性能和热舒适性。

Causes include heating too quickly in the feed zone, melting too slowly in the transition zone, insufficient mixing, and excessive heat loss in the adapters or die.

其原因包括在喂料区加热时间太短和在过渡区熔融太慢、混合不良、在机筒和口模中存在过多的热量损失。

The gas engine-driven heat pump (GEHP) is a high performance and environment-friendly equipment that can provide heating and cooling, but at present the study on the GEHP is insufficient in China.

燃气机热泵是一种高效节能、经济环保的新型供热空调装置，国内对该装置的研究正处于起步阶段。
