The invention discloses an underground water source heat pump heat source well with multistage flow adjustment, which relates to an underground water source heat pump heat source well. The invention mainly solves the problem of narrow flow adjustment range of the prior underground water source heat pump. A pumping well and a refilling well are vertically arranged in parallel; one end of a main pipe is inserted into the pumping well, and the other end of the main pipe is communicated with a heat exchanger; a first branch pipe and a second branch pipe are vertically arranged in the pumping well in parallel, and the upper ends of the first branch pipe and the second branch pipe are communicated with one end of the main pipe; a first water pump and a first electromagnetic valve are sequentially installed on the first branch pipe from bottom to top; a second water pump and a second electromagnetic valve are sequentially installed on the second branch pipe from bottom to top; one end of a refilling pipe is communicated with the heat exchanger, and the other end of the refilling pipe is inserted into the refilling well. The underground water source heat pump heat source well can adjust four grades of 0, 1/3, 2/3 and 1 of the water pumping amount of a single well along with the change of a load of a heat pump by changing a running water pump.
Description
Technical field
The present invention relates to a kind of underground water source heat pump heat source well.
Background technology
At present the well numbers that adopt are regulated and the variable frequency pumps adjusting more during the groundwater heat pump Flow-rate adjustment, but the adjustable range of two kinds of methods is all very narrow.Need many mouthfuls of pumped wells when the well number is regulated, and adjustable range is limited, draw water during the variable frequency pump adjusting flow and lift respective change, flow adjustment range is narrower.
Summary of the invention
The objective of the invention is in order to solve the problem of existing groundwater heat pump narrow flow adjustment range, and then the underground water source heat pump heat source well that provides a kind of multistage flow to regulate.
Technical scheme of the present invention is: the underground water source heat pump heat source well that a kind of multistage flow is regulated is by pumped well, first suction pump, first magnetic valve, second suction pump, second magnetic valve, drinking-water pipe, heat exchanger, recharging pipe and inverted well forms, described pumped well and inverted well vertically are set up in parallel, described drinking-water pipe is by main pipe, first arm and second arm are formed, one end of described main pipe is inserted in the pumped well, the other end of described main pipe is communicated with heat exchanger, described first arm and second arm vertically are set up in parallel in the pumped well, and the upper end of first arm and second arm is communicated with an end of main pipe, described first suction pump and first magnetic valve are installed on first arm from the bottom to top successively, second suction pump and second magnetic valve are installed on second arm from the bottom to top successively, a described end that recharges pipe is communicated with heat exchanger, and the other end that recharges pipe is inserted in the inverted well.
The present invention compared with prior art has following beneficial effect: the present invention is by transforming existing groundwater heat pump energy regulating system, underground water source heat pump heat source well can be along with the variation of heat pump load, by the water pump that change puts into operation, realized 0,1/3,2/3 and 1 four other adjusting of level of individual well pump-out.
Description of drawings
Fig. 1 is that overall structure master of the present invention looks schematic diagram.
The specific embodiment
The specific embodiment one: present embodiment is described in conjunction with Fig. 1, the underground water source heat pump heat source well that a kind of multistage flow of present embodiment is regulated is by pumped well 1, first suction pump 2, first magnetic valve 3, second suction pump 4, second magnetic valve 5, drinking-water pipe 6, heat exchanger 7, recharge pipe 8 and inverted well 9 compositions, described pumped well 1 vertically is set up in parallel with inverted well 9, described drinking-water pipe 6 is by main pipe 6-1, the first arm 6-2 and the second arm 6-3 form, the end of described main pipe 6-1 is inserted in the pumped well 1, the other end of described main pipe 6-1 is communicated with heat exchanger 7, the described first arm 6-2 and the second arm 6-3 vertically are set up in parallel in the pumped well 1, and the upper end of the first arm 6-2 and the second arm 6-3 is communicated with the end of main pipe 6-1, described first suction pump 2 and first magnetic valve 3 are installed on the first arm 6-2 from the bottom to top successively, second suction pump 4 and second magnetic valve 5 are installed on the second arm 6-3 from the bottom to top successively, a described end that recharges pipe 8 is communicated with heat exchanger 7, and the other end that recharges pipe 8 is inserted in the inverted well 9.Described heat exchanger 7 is produced by the prompt agate heat exchange equipment in Guangzhou Co., Ltd.
The specific embodiment two: in conjunction with Fig. 1 present embodiment is described, the drinking-water pipe 6 of present embodiment is anticorrosion spiral welding steel pipe.So be provided with, anticorrosion strengthens the pipeline anti-pressure ability simultaneously.Other composition is identical with the specific embodiment one with annexation.
The specific embodiment three: in conjunction with Fig. 1 present embodiment is described, the pipe 8 that recharges of present embodiment is anticorrosion spiral welding steel pipe.So be provided with, anticorrosion strengthens the pipeline anti-pressure ability simultaneously.Other composition is identical with the specific embodiment one or two with annexation.
Operation principle of the present invention: operation principle of the present invention is described in conjunction with Fig. 1, in underground water source heat pump heat source well, the design of the first suction pump 2 flow design of 2/3, the second suction pump 4 of flow flow 1/3 of the flow that draws water for system designs that draws water that draws water for system designs that draws water.When heat exchanger 7 oeprations at full load, first magnetic valve 3 and second magnetic valve 5 are opened simultaneously, and first suction pump 2 and second suction pump 4 move simultaneously, the water yield demand of drawing water and satisfying groundwater heat pump.When heat exchanger 7 load drop to have only the design load 2/3 the time, the required pump-out of groundwater heat pump is also reduced to 2/3 of the design water yield, this moment, first magnetic valve 3 was opened, second magnetic valve 5 cuts out, first suction pump, 2 operations accordingly, second suction pump 4 is out of service, and total water yield of pumped well 1 is to design 2/3 of the water yield like this, satisfies the demand of groundwater heat pump.When heat pump load drops to when having only design load 1/3, the required pump-out of groundwater heat pump is also reduced to 1/3 of the design water yield, this moment, second magnetic valve 5 was opened, first magnetic valve 3 cuts out, second suction pump, 4 operations accordingly, first suction pump 2 is out of service, and total water yield of pumped well 1 is to design 1/3 of the water yield like this, satisfies the demand of groundwater heat pump.The flow direction of water is referring to direction shown in the arrow among Fig. 1.Underground water source heat pump heat source well of the present invention like this can by the water pump that change puts into operation, be realized the adjusting of 0,1/3,2/3,1 level Four of pump-out along with the variation of load.
