As an example of waste air conditioning we looked at the cost and decided no installing instead an idea I saw on one of the English programs about house refurbishment Pumping air through buried pipes results in very cool air for the cost of burning z very small light bulb and a tiny percentage of a/c It did involve some trenching and finding some plastic pipe being still cheaper than just the install labour cost of one split a/c over all an immensly satisfing outcome at least 4 times a year Great idea! ( 2 metres down the earth never gets above 5 Deg C) in Brisbane I find that impossible to believe as the air temperature would hardly ever or never get below that. Otherwise you are telling me there is a BIG heat sink buried under the city because if the soil is being heated by air at 15-35C from above that heat would have to go somewhere if the subsoil is at 5C. Sorry the physics makes no sense. Perhaps it's a typo? David |
