Abstract
The utility model relates to an air conditioner and heat supply technical field, concretely relates to three advance a spiral ground heat exchanger that buries. The water-saving device comprises a conical joint, a first spiral water inlet pipe, a second spiral water inlet pipe, a third spiral water inlet pipe and a vertical water return pipe, wherein the conical joint comprises four interfaces and the interiors of the conical joint and the first spiral water inlet pipe, the second spiral water inlet pipe, the third spiral water inlet pipe and the vertical water return pipe are. The first spiral water inlet pipe, the second spiral water inlet pipe, the third spiral water inlet pipe and the vertical water return pipe are respectively combined with a conical joint which comprises four joints and is internally communicated with one another, so that the three-in one-out spiral ground heat exchanger is formed. The first spiral water inlet pipe, the second spiral water inlet pipe and the third spiral water inlet pipe are placed around the vertical water return pipe along the same spiral direction. The heat exchange length in the unit heat exchange well is increased through the first spiral type water inlet pipe, the second spiral type water inlet pipe and the third spiral type water inlet pipe, the heat exchange efficiency of the unit heat exchange well is improved, the punching quantity is reduced, the punching cost of the ground source heat pump system is reduced, and the economical efficiency is considerable.
Description
Technical field
The utility model relates to air-conditioning and heat supply process field, is specifically related to a kind of three and enters an exit spiral type ground heat exchanger.
Background technology
Along with the raising of expanding economy and people's living standard, the confession of public building and house is warmed up the requirement that air-conditioning has become general.But due to traditional heating system energy utilization rate low, seriously polluted, the earth source heat pump of more energy-conserving and environment-protective replaces traditional heating system gradually.Earth source heat pump is the Novel air condition device utilizing superficial-layer geothermal energy to carry out the high-efficient energy-saving environment friendly of heating and refrigerating, it is the heat storage and cold accumulation ability utilizing underground huge, by buried in Around Buildings or underfloor pipe-line system, heat pump principle is adopted to make underground Rock And Soil and building complete a kind of technology of heat exchange.The unit heat exchange well heat exchange area of conventional vertical buried tube heat exchanger is few, can not make full use of the exchange capability of heat of unit heat exchange well, such that drilling hole amount increases, boring expense increases, the development of restriction earth source heat pump.
Utility model content
For above shortcomings in prior art, the purpose of this utility model is to provide a kind of three to enter an exit spiral type ground heat exchanger, to be improved by structure, the heat exchange property of ground heat exchanger is strengthened, effectively can improve the heat exchange area in unit heat exchange hole, cause the problems such as earth-source hot-pump system punching quantity increases, investment is high to solve existing ground heat exchanger structure.
In order to solve the problem, the utility model have employed following technological means: a kind of three enter an exit spiral type ground heat exchanger, comprise the first spiral water inlet pipe, second spiral water inlet pipe, 3rd spiral water inlet pipe, vertical return pipe comprises four interfaces with one and the Tapered nipple that is connected of internal mutual, vertical return pipe is positioned at the centre of Tapered nipple, first spiral water inlet pipe, second spiral water inlet pipe and the 3rd spiral water inlet pipe lay respectively at around vertical return pipe, and upwards extend along vertical return pipe with the identical hand of spiral.
After the utility model adopts technique scheme, compared with prior art there is following beneficial effect: one is that return pipe is effectively isolated three water inlet pipes, the spacing of three water inlet pipes is widened, mutually disturb when being conducive to reduction three water inlet pipes and surrounding soil heat exchange, thus increase the heat exchange amount between underground pipe and soil; Two is water inlet pipe helically types, the effective heat exchange area increasing ground heat exchanger in unit heat exchange well.Can reduce punching quantity, reduce the boring expense of earth-source hot-pump system, economy is considerable.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is schematic diagram of the present utility model.
Fig. 1 layout illustrates: 1 is taper joint, and 2 is first spiral water inlet pipes, and 3 is second spiral water inlet pipes, and 4 is the 3rd spiral water inlet pipes, and 5 is vertical return pipes.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
A kind of three enter an exit spiral type ground heat exchanger, comprise shown in Fig. 1 and comprise four interfaces and the internal mutual spiral water inlet pipe 3 of Tapered nipple the 1, first spiral water inlet pipe 2, second, the 3rd spiral water inlet pipe 4, the vertical return pipe 5 that are connected.See Fig. 1, the spiral water inlet pipe 3 of first spiral water inlet pipe 2, second, the 3rd spiral water inlet pipe 4, vertical return pipe 5 comprises three interfaces with one respectively and the Tapered nipple 1 that internal mutual is connected is combined and just become a kind of three to enter an exit spiral type ground heat exchanger.The spiral water inlet pipe 3 of first spiral water inlet pipe 2, second, the 3rd spiral water inlet pipe 4 are placed along same-handed direction around vertical return pipe 5.The heat exchange length in unit heat exchange well is added by the spiral water inlet pipe 3 of the first spiral water inlet pipe 2, second, the 3rd spiral water inlet pipe 4, and improve the heat exchange efficiency of unit heat exchange well, reduce punching quantity, reduce the punching expense of earth-source hot-pump system, economy is considerable.
Claims (1)
1. one kind three is entered an exit spiral type ground heat exchanger, it is characterized in that: described ground heat exchanger comprises the Tapered nipple that a top has four interface internal to interconnect, in the middle of described joint, an interface connects with a rectilinear return pipe, around described joint three interfaces respectively water inlet pipe spiral with first, the second spiral water inlet pipe, the 3rd spiral water inlet pipe connect, described first spiral water inlet pipe, the second spiral water inlet pipe, the 3rd spiral water inlet pipe are placed along same-handed direction around a described rectilinear return pipe.
