Description
Technical field
The utility model belongs to refrigeration technology field, is specifically related to a kind of air refrigerating devie of domestic air conditioning.
Background technology
At present, domestic air conditioning mostly adopts vapour compression refrigeration technology, refrigerating plant is generally conventional steam compression refigerating machine, it is not only to consume motor power completely as cost, and need to adopt freon as cold-producing medium, not only price is higher, also has certain toxicity, to can produce compared with severe contamination atmospheric environment, cannot meet the requirement of the working medium feature of environmental protection.On the other hand, although air is as cold-producing medium application already on air separation and civil aircraft, due to shortcomings such as normal air refrigerating plant exist efficiency low, and equipment is huge, it cannot be widely used in family expenses air conditioner refrigerating.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of air refrigerating devie of domestic air conditioning, to solve the existing many defects of existing domestic air conditioning refrigerating plant.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of air refrigerating devie of domestic air conditioning, comprise high-speed electric expreess locomotive, compressor, decompressor, main shaft and heat exchanger, it is characterized in that: described compressor, decompressor are positioned at the axial the same side of high-speed electric expreess locomotive, described compressor outlet via heat exchanger UNICOM to expander inlet, wherein said compressor is between decompressor and high-speed electric expreess locomotive, and three coaxially connects, coaxially works through main shaft.
Described compressor, decompressor are provided with air bearing or magnetic suspension bearing as main shaft supporting structure with main shaft junction, are oil-free lubrication system;
Described compressor is one or more levels centrifugal turbo-compressor;
Described decompressor is one or more levels turbine type decompressor.
The beneficial effects of the utility model are:
(1) directly adopt air as refrigerant, no longer need freon as cold-producing medium, can effectively reduce greenhouse effects, be beneficial to energy-saving and emission-reduction, protection of the environment;
(2), because of the pressure-air acting of expanding in decompressor, can make decompressor reclaim the power resources of expansion work as drive compression machine.The power that the rotatablely moving of decompressor can be supplemented motor to greatest extent makes compressor carry out high speed rotary motion motion, therefore high-speed electric expreess locomotive only need provide a small amount of electric power just can meet the required driving force of refrigeration, motor load and power consumption are effectively reduced, improve refrigerating efficiency, and steady without pressure, there is not the problem that starting current is large;
(3) between compressor and decompressor, adopt air bearing or magnetic suspension bearing as main shaft supporting structure, by the compressed air importing in operation process middle (center) bearing chamber, main shaft is suspended in air, realized motor at 50,000 revs/min---100,000 revs/min while running up accurately, stable, thereby can efficiently carry out centrifugal compression to gas, because air bearing can be without oil work, the heat of generation is little, therefore whole apparatus structure compactness, spindle operation is stable, precision is high;
(4) simple and reasonable, easy to connect, there is volume little, lightweight, system pressure is low, the feature that seal request is low;
(5) long service life, performance safety is reliable, and trouble shooting rate is low, and applicability is strong, can extensively replace existing various families operation of air conditioning systems.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1, a kind of air refrigerating devie of domestic air conditioning, its assembly comprises: high-speed electric expreess locomotive 1, compressor 2, decompressor 3, main shaft 4 and heat exchanger 5, the gas outlet of compressor 2 is the air inlet to decompressor 3 via heat exchanger 5 UNICOMs, wherein compressor 2, decompressor 3 are positioned at the axial the same side of high-speed electric expreess locomotive 1, and compressor 2 is between decompressor 3 and high-speed electric expreess locomotive 1, and three coaxially connects, coaxially works through main shaft 4.
Described compressor 2, decompressor 3 are provided with air bearing or magnetic suspension bearing as main shaft supporting structure with main shaft 1 junction, oil-free lubrication system;
Described compressor 2 is one or more levels centrifugal turbo-compressor;
Described decompressor 3 is one or more levels turbine type decompressor.
Operation principle of the present utility model is: high-speed electric expreess locomotive is after main shaft drives compressor, decompressor running, and room air is sucked by compressor, and is compressed into high temperature and high pressure gas.The heat that high temperature and high pressure gas produces when compression through heat exchanger cements out, and this heat can heat also heating etc. in the winter time of domestic water, if do not needed can be dispersed in atmosphere.Inferior low temperature high pressure gas after heat exchange enters adiabatic constant entropy expansion after decompressor, gases at high pressure do work by driving decompressor after expanding, the temperature of gas sharply reduces simultaneously, through this physical process, Compressed Gas becomes low-temperature atmosphere-pressure gas and enters the indoor absorption refrigeration that carries out, and indoor temperature is declined gradually, and compressor just sucks again and compresses at cooling air simultaneously, enter next circulation, until room temperature reaches controlled temperature.Another air bearing or almost idle of magnetic suspension bearing because of supports compressor and decompressor running, and the work done during compression that reclaims decompressor expands and does work and the common drive compression machine rotation of high-speed electric expreess locomotive, therefore after fully turning round, high-speed electric expreess locomotive only need provide a small amount of electric power just can meet the required driving force of Compressed Gas.Because this air refrigerating devie will expand in the direct flood chamber of cooled Cryogenic air, omit the indoor heat exchanger of traditional air-conditioning system, therefore use the air-conditioning system of this air refrigerating devie will the more efficient and environmental protection than traditional air-conditioning system.
