Web11 Jan 2024 · Is there a current passive miniature air well (condenser)? My container design can be changed to fit the condenser (so it is irrelevant). Therefore I would like to find a passive condenser that is small enough but enough to water a plant continuously. (note: I am not asking for a product, I am asking for a mechanism or a technology or a method) WebThis problem is well solved in the so-called passive houses. Application of the passive houses technologies allows a 90% reduction in the heat leakages in the building. In such systems, almost no heat leakage from the outside and thus air-conditioning system should remove the heat released only by the internal heat source, i.e. appliances and ...
