但采用双掺防冻剂和泵送剂的方法不可取，科学合理的方法是采用防冻泵送剂。
But the method of mixing anti freeze and pumping aid together into concrete is not advisable, and the scientific technology is using anti freezing pumping aid in concrete.
地热泵的工作方式与普通的热力泵相同，区别只是地热泵是从地下吸热而不是从空中。在冬季，地热泵会将水与乙二醇(防冻剂)的混合物泵入深入地热井的管道中进行循环。
The Geothermal Heat pump: the pump USES a small amount of electricity to pump a mixture of water and antifreeze through two loops of pipe in the ground Paul wootton.
如果在冬天泳池处于半运行状态，且过滤器的泵装有一个防冻温控器，则加热器内可以充满水。
If the pool is to be kept in semi-operation during the winter then the heater may only be left full of water.
使用水(或防冻液)作为媒介，使用泵循环热量或冷却水。
Water (or Antifreeze Coolant Liquid) is used as the media and a pump is used to circulate the heat or cool water.
