Well water for cooling in summer and heating in the winter instead of GHE (Ground Heat Exchanger)
Ground heat exchangers have a number of drawbacks discussed earlier ground heat exchanger advantages and disadvantages. On some particularly agricultural plots and farms can provide an alternative which is much better and more effective from GHE.
Old farms usually have water wells will be even cheaper solution than.
Described method allows cooling down air for recuperator in summer and heating up in winter.
For efficient cooling and heating installation can create a water heat exchanger submerged at the bottom of the well of the vertebral and water Radiator (cooler/heater) for clean air just before entering the recuperator. heat exchanger and heater must be connected in a closed circuit equipped with a circulation pump active while recuperator is running. The system shall be filled with nonfreezing fluid for coolers and standard protection against pressure changes as the diaphragm expansion vessel.
The operation of such a solution is very simple (ground water in the well has winter temperatures from 5 to several degrees C. ensuring the circulation pump in the system allows it to warm the air passing through the radiator/water heater. The efficiency of this approach depends on the effective recovery of the cooler/heater and a heat exchanger in a well . This arrangement has a much lower pressure loss than GHE (eg 100m). Additionally, maintenance is possible (cleaning , fumigation cooler/heater in a simple way , eg. such as car air conditioning.
In a very simple way you can still increase the efficiency of the system , by pouring water from wells. This influx of fresh groundwater with better temperatures ( higher in winter and cooler in summer). This maximally shorten recovery time of source which is incomparable small to GHE.
Depending on the location and size of the plot water from the well can spill to the garden , pour into a household sewage treatment plant, existing drainage ditches adjacent to the plot or pour into a second well, what is commonly done in heat pumps sources.
In summer, the system cools the air input to the recuperator or ventilator the same way as it did in the case of GHE.
In this case, using efficient wells and heat and cooling , high efficiency balance expenditure and income goes much more favorable than in the case of ground heat exchangers . Possibility of cleaning and maintenance is also indisputable advantage which is unrealistic in the case of GHE (eg. 100m pipe fi.200mm 3m under ground.
Additional possibility to further increase the efficiency of the heating system is switched input on the solar collector recuperator air on sunny days in winter . This regeneration sources ( wells ) and make very significant energy gain, increasing profits and use the free energy.
Of course, as in the case is of GHE it requires smart Home , intelligent Building , that automate home automation control the installation , that it is maintenance-free and works with maximum efficiency by providing fast payback period.
home Automation protect the system from damage and ensure its long-term work and collaboration with all the equipment of boiler and central heating boiler control , control recuperation , ventilation control , control of central heating
