aAn antifreeze solution (or refrigerant in the case of a DX earth-energy system), which has been chilled by the heat pump’s refrigeration system to several degrees colder than the outside soil, circulates through the piping and absorbs heat from the surrounding soil. 防冻液 (或冷冻剂在DX地...

In this study, the effects of\nantifreeze in the circulating water on operation performance of ground heat exchangers (GHEs) was\ninvestigated. A theoretical model was derived to analyze the antifreeze effect. Then the model was\nvalidated by an experimental system. Based on the effects of ...
aThe direction of the refrigerant flow is changed by the reversing valve. 扭转的阀门改变冷却液流程的方向。[translate] aThe refrigerant picks up heat from the house air and transfers it directly, in DX systems, or to the ground water or antifreeze mixture. 正在翻译,请等待...[translate]...
Therefore, EG is often used as an antifreeze in ZHSCs85,86. In general, gel electrolytes tend to fail at high temperatures. As a response, heat-resistant and nonflammable polymer electrolyte (HRNPE) films with the pyrrolidinium-based IL (1-methyl-1-propylpyrrolidine bis(trifluoromethyl sulfonyl)...
In a large volume space with air conditioning systems typically with air upper blowing in and lower return, or in hot summer days, near the floor, the air temperature is nearly constant due to the heat transfer between the air, the floor, the vented doors and windows, and the walls. ...
The unit must be installed in the equipment room with a raised floor. Take appropriate thermal insulation and antifreeze measures for outdoor water pipes to avoid poor drainage and insufficient water supply caused by freezing. When installing, seal the top of the NetCol8000-A by using...
The rear bedrooms also have less solar exposure and have the old radiators instead of under floor heat. So the duration of the call for heat is longer. Even so, the by afternoon it was warm enough and didn’t resume until after sunset. Rear bedroom radiators 1/14 The next day the ...
