Description
Technical field
The present invention relates to a kind of underground water source heat pump heat source well.
Background technology
There is the underground water source heat pump heat source well of some to adopt individual well circulation underground heat exchange system at present, though this thermal source well integrates traditional pumped well and inverted well, under the multi-parameter comprehensive action condition, occur easily recharging bad, " heat breaks through " temperature of drawing water seriously, is year by year crossed low or cross the high problem that influences the normal operation of heat-exchange system.
Summary of the invention
The objective of the invention is for solve existing thermal source well under the multi-parameter comprehensive action condition, occur easily recharging bad, " heat breaks through " temperature of drawing water seriously, is year by year crossed low or cross the problem that high influence is the normal operation of heat exchange system, and then provides a kind of groundwater heat pump list twin-well mixing thermal source well.
Technical scheme of the present invention is: a kind of groundwater heat pump list twin-well mixing thermal source well comprises individual well circulation thermal source well, drinking-water pipe, first recharges pipe, two stop valves, suction pump and heat pump, described mixing thermal source well comprises that also second recharges pipe, magnetic valve, inverted well, two temperature sensors and two output lines, described individual well circulation thermal source well and inverted well vertically are set up in parallel, in the one end plug-in mounting individual well circulation thermal source well of described drinking-water pipe, the other end of drinking-water pipe is communicated with heat pump, described suction pump is installed on the drinking-water pipe and with drinking-water pipe and is communicated with, described first end that recharges pipe is inserted in the individual well circulation thermal source well, first other end that recharges pipe is communicated with heat pump, described second end and first that recharges pipe recharges pipe and is communicated with, second other end that recharges pipe is communicated with inverted well, described first recharge the pipe and drinking-water pipe on a stop valve respectively is installed, described second recharges magnetic valve is installed on the pipe, described two temperature sensors are installed in first respectively and recharge on pipe and the drinking-water pipe, and described two temperature sensors are connected with magnetic valve by an output line respectively.
The present invention compared with prior art has following beneficial effect: when " heat breaks through " is serious, the present invention is by the discharging underground raw water, alleviated the variation of temperature of drawing water, kept moderate underground water temperature, thereby the increase system bears the ability of peak load, improve source pump efficient, can also avoid phreatic freezing.When the thermal source well adopts Flow-rate adjustment, to draw water for big flow, when difficulty or obstruction perhaps occurring recharging, the discharging underground raw water reduces the amount of recharging of individual well circulating groundwater heat-exchange system under the condition of protection groundwater resources, alleviate and recharge pressure.When cooling and heating load seriously uneven, low or too high phenomenon appears crossing year by year in the temperature of drawing water, also promptly along with the operation of heat pump, when the water-bearing layer has stored too much cold or heat, reduce cold or the heat that enters individual well circulation underground heat exchange system by the discharging underground raw water, thereby regulated the temperature of drawing water.To sum up, that thermal source well of the present invention has been avoided recharging is bad, " heat breaks through " temperature of drawing water seriously, year by year cross low or too high, thereby realized being the normal operation of heat exchange system.
