地板、墙壁加热、制冷、房顶种草皮、更多的是在房顶安装太阳能热水器，热泵技术采集空气中分散的热量"为我所用"，过滤器可有效地收集空气中细小的尘埃，从而能够抑制霉菌等过敏生物繁殖。

Direct exchange heat pumps are not to be confused with water-source heat pumps or water loop heat pumps since there is no water in the ground loop.

直接交流热泵是不能混为一谈"水源热泵"或"水环热泵系统"，因为没有循环水在地上。

The main reasons for the higher efficiency are the elimination of the water pump, the elimination of the water heat exchanger (which is a source of heat losses), and the phase change of the refrigerant in the ground itself, allowing a higher temperature gradient between loop and ground resulting in a higher rate of heat transfer.

为高效率的主要原因是水的泵，水的热交换（这是一个消除热损失的来源），以及本身在地面制冷剂相变，从而使一回路和地面之间的热传递率较高导致较高的温度梯度。

Solar irradiation absorber, heat storage and insulation are the main effect factors of the passive solar heating room Heat transfer and gas flow in rock bed worked as solar absorber and storage layer have also been studied, including transport properties.

被动式太阳能温室-采暖房，分析采暖房北墙采用或不采用隔热保温措施时，温室-采暖房内的温度和气流分布情况，模拟具有蓄热层的太阳能温室-采暖房中的对流传热，表明集热、蓄热、隔热是太阳能温室蓄热型采暖房的三个重要方面。

This is because temperature depends not only on the amount of heat the atmosphere receives from the sun, but also on the amount of heat it loses due to the absorption of this heat by the ground and ocean.

这是由于气温不但取决于大气所接受阳光的热量还取决于它损失的被陆地和海洋所吸收的热量。

The results reveal the characters of the urban heat island effect. The extent of the heat island expands distinctly and the thermal environment worsens, however, the strength of heat island in the center of the urban area decreases and its spatial pattern becomes more complex.

研究结果揭示，20世纪90年代上海市主城区热岛范围显著扩大，但中心城区的热岛强度在下降，空间格局也趋于复杂；通过分析，城市热环境空间格局动态演变是不同尺度上、相互嵌套、相互影响的多种驱动力的综合作用结果。

All organisms gain heat from and lose heat to their environment as well as producing heat.
