Geothermal heating and cooling systems (heat pumps) use the technology of refrigeration and the cost-free heat from the earth. ECI REC believes geothermal systems are incredibly productive in employing electric energy much more efficiently, and we encourage all members taking into consideration new house construction or a heating and cooling method upgrade to think about this technologies.
Once all the existing power loads have been evaluated and modifications have been made to boost the power efficiency of a household, then look at renewable and alternative power possibilities such as: solar thermal water and space heating, solar photovoltaic (PV) electrical energy, and property wind energy (if sensible). Highly power effective geothermal heating and cooling systems could also be evaluated to give more energy efficiency improvements.
Water excellent is also an critical aspect when evaluating a source for an open loop method. Water that is very alkaline or complete of minerals can lead to heavy scaling on the heat exchanger, leading to increasingly poor efficiency more than time. Some scaling is anticipated for most systems and can be removed every 1 to 3 years working with an acid wash. This periodic maintenance has to be performed by a certified technician since specialized pumps and robust acid are involved. If the water PH is less than 7.five and contains less than one hundred ppm calcium descaling can be performed less typically or not at all.
Adsorption (with a ‘d’ as an alternative of a ‘b’ in the second letter) Chillers () working with a desiccant might be additional efficient (I have not evaluated these so far), as pointed out by Warwick, mainly because these would not call for to sink the heat created by the solar panel and would need to sink only the heat extracted from the creating. This would be a significant benefit for this technology.
Cooling towers which are constructed in whole or in component of combustible materials can support propagating internal fires. The resulting damage can be sufficiently serious to demand the replacement of the complete cell or tower structure. For this cause, some codes and requirements advocate combustible cooling towers be supplied with an automatic fire sprinkler system. Fires can propagate internally inside the tower structure throughout upkeep when the cell is not in operation (such as for maintenance or building), and even when the tower is in operation, in particular those of the induced-draft sort due to the fact of the existence of fairly dry areas inside the towers.
