Geothermal heating and cooling device is disclosed.
Geothermal heating and cooling apparatus is disclosed as capable of performing heating and cooling on demand by using the smelting, as a geothermal exchange fluid flows and underground geothermal heat exchange member for heat exchange; And to supply the fluid circulation for the consumer, consisting of the temperature stratification to be circulated fluid is stratified according to the temperature inside the heat storage tank; The geothermal exchange member and are connected with the heat storage tank, the geothermal transfer heat to the heat storage tank in the exchange member, or heat pump that can deliver the heat to the geothermal exchange member in the heat storage tank; The heat storage tank and the top, the flow tube connecting the upper side heat storage tank the heat storage tank top and the heat pump cycle to a relatively high temperature of the fluid to flow between the heat pump; The heat storage tank and the lower-side lower flow tube to a thermal storage tank, connected to the heat storage tank and the lower the heat pump between the heat pump to a relatively low temperature of the circulating fluid flows; A first three-way valve that is installed in any one of the heat storage tank-side upper flow tube and the heat storage tank-side lower flow tube (triple valve); Circulating fluid to the relatively high temperature of the heat storage tank upper part can be supplemented with the first three-way valve, supplement water pipe connecting the first three-way valve and the heat storage tank upper part; And so that the circulating fluid in the relatively low temperature of the heat storage tank lower portion can be supplemented to the first three-way valve, the cold water replenishment pipe connecting the first three-way valve and the heat storage tank lower part; including, above and the heat storage tank-side upper flow tube when circulation of the circulating fluid which is flowing along the heat storage tank-side lower flow tube is insufficient to the required circulation amount, characterized in that the water replenishment pipe and the cold water replenishment pipe at least the circulation fluid in the heat storage tank through one of the supplemented to the first three-way valve It shall be.
According to the geothermal heating and cooling system is started, hit the first three-way valve is installed the pump and on the storage tank side lower flow pipe connecting the storage tank, hot water replenishment pipe and cold supplements that are each connected to the upper diffuser and lower diffuser in the thermal storage tank tube first according to the connected to the first three-way valve, when the circulation amount of the circulating fluid which is flowing along the heat storage tank-side upper flow tube and a thermal storage tank-side lower flow tube is insufficient to the required circulation amount, circulating the fluid in the water replenishment pipe and heat storage tank via at least one of cold water replenishment pipe is the three-way valve may be supplemented by one. Then, there is an advantage that the shortages of the circulating fluid can be prevented that during operation of the geothermal heating and cooling device to cycle through the heat pump and the heat storage tank according to the heat storage tank and heat storage tank-side lower flow tube side upper flow tube.
