Description
Technical Field
The utility model relates to an economizer is used to fluorine for air source heat pump belongs to economizer technical field.
Background
The current air source heat pump is more and more extensive, but current air source heat pump receives climate influence great, and when ambient temperature was lower, heat pump efficiency can descend by a wide margin, and china's region is wide at that time, and in the area with north in the yellow river basin, traditional heat pump is subject to low temperature heat pump efficiency inadequately, can't promote comprehensively, needs the improvement, and current economy ware for fluorine is mostly plate heat exchanger, and heat exchange efficiency is low, and the loss of heat transfer temperature difference is big, is not suitable for air source heat pump.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes the defects of the prior art and provides an economizer for fluorine, which has simple and stable structure and high heat exchange efficiency.
In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides an economizer is used to fluorine for air source heat pump, includes inner tube and outer tube, and the inner tube cover is established in the outer tube, forms the heat transfer space between inner tube and the outer tube, and outer tube and inner tube are spiral coil, and outer tube one end sets up the outer tube import, and the other end sets up the outer tube export, and inner tube one end sets up the inner tube import, and the other end sets up the inner tube export, and the outer tube import is close to the inner tube export, and the outer tube export is close.
The inner pipe and the outer pipe are coaxially arranged.
And a closed space is formed between the outer wall of the inner pipe and the inner wall of the outer pipe.
The inner pipe and the outer pipe are made of copper.
The inlet of the inner pipe and the outlet of the inner pipe form a circulating pipeline.
The inlet of the inner pipe and the outlet of the inner pipe are vertical to the inner pipe and the outer pipe.
Compared with the prior art, the utility model following beneficial effect has: the spiral coil type sleeve structure is used, so that heat exchange distance can be increased, heat exchange area is increased, installation space and installation difficulty are reduced, utilization of pipes can be reduced, processing difficulty is reduced, and heat exchange efficiency is improved.

Detailed Description
As shown in fig. 1 and 2, the utility model relates to an economizer is used to fluorine for air source heat pump, including inner tube 1 and outer tube 2, 1 cover of inner tube is established in outer tube 2, form the heat transfer space between inner tube 1 and the outer tube 2, outer tube 2 is spiral coil with inner tube 1, 2 one end of outer tube sets up outer tube import 3, the other end sets up outer tube export 4, 1 one end of inner tube sets up inner tube import 5, the other end sets up inner tube export 6, outer tube import 3 is close to inner tube export 6, outer tube export 4 is close to inner tube import 5, inner tube 1 and 2 coaxial arrangements of outer tube, form airtight space between 1 outer wall of inner tube and the 2 inner walls of outer tube, inner tube 1 is the copper with 2 materials of outer tube, inner tube import 5 forms circulation pipeline 7 with inner tube export 6, inner tube import 5, inner tube export.
When the utility model is used, the high-pressure liquid refrigerant from the condenser is divided into two parts, one part enters from the inlet of the inner pipe and then comes out from the outlet of the inner pipe to form a circulation pipeline, the other part enters from the inlet of the outer pipe and comes out from the outlet of the outer pipe, the freon refrigerant in the inner pipe throttles in the inner pipe in a long stroke of the coil pipe so as to effectively reduce the temperature of the refrigerant in the outer pipe and supercool the refrigerant, the liquid in the supercooled outer pipe enters the evaporator through the throttle valve, the refrigerant in the inner pipe reduces the temperature after throttling so as to absorb the heat of the other part of refrigerant to evaporate into overheated gas to enter the compressor for compression circulation, the system heating capacity can be effectively improved and the exhaust temperature of the compressor can be reduced, the inlet and the outlet of the inner pipe are circulation pipelines, and simultaneously, the inlet and the outlet, reducing flash gas, guaranteeing the throttling effect, the heat exchange length is as long as 2.8 meters, the return gas can fully reach an overheat state, liquid is prevented from entering the compressor to cause liquid impact on the compressor, the process is simple, and the installation is convenient.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
