Description
Technical field
This utility model belongs to refrigeration technology field, particularly to a kind of compressed air refrigeration and prepare hot water apparatus.
Background technology
Air-conditioning refrigeration system is typically all and uses steam compression type refrigeration technology, its vapor compression refrigerating machine is to consume electric power completely as cost, the freon refrigerant used is the most expensive but also atmospheric ozone layer is had destruction, working medium environmental requirement cannot be met, international convention is used by restriction, although brainstrust is at actively research freon refrigerant substitute, having partial substitute to have toxicity and explosivity, the life to the mankind has unpredictable harm.Generally domestic air conditioning outdoor heat exchanger uses air-cooled form, is expelled directly out outdoor, not only wastes the energy but also ambient atmosphere ambient temperature can be made to raise after cooling wind heat absorption.
The major advantage utilizing compressed air refrigeration is: it is safe and reliable that air makees cold-producing medium, and it is convenient to obtain, do not exist cold-producing medium buy, the intermediate link such as storage and Pollutant Treatment, and equipment quality is little, regulation and easy to control, overhauls and the workload safeguarded is little.Working medium air is cold-producing medium and refrigerating medium, can be directly inputted to room wet to absorb more than waste heat, makes ventilation of room and refrigeration be completed by same system.And the used heat that heat exchanger is discharged can lead to supercooled water and recycle.
Using air compressor and decompressor to be all isolated operations about air cooling in the market, and air compressor only carries out one stage of compression, do not carry out multi-stage compression, when this refrigeration system is run, refrigerating efficiency is low, power consumption.
Summary of the invention
The purpose of this utility model is: for the deficiencies in the prior art, this utility model provides a kind of compressed air refrigeration and provides the device of hot water, while solving many defects that existing domestic air conditioning refrigerating plant exists, make full use of energy, provide domestic hot-water for daily life.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of compressed air refrigeration and prepare hot water apparatus, including motor, air compressor unit, outdoor heat exchanger, header tank, turbo-expander, described air compressor unit includes main air compressor and rear class air compressor, described motor is connected with main air compressor, described rear class air compressor is connected with outdoor heat exchanger, described outdoor heat exchanger is connected with header tank and turbo-expander respectively, described rear class air compressor and turbo-expander are coaxially connected by aerostatic bearing, and described turbo-expander drives rear class air compressor to rotate.
Described rear class air compressor refer to after workflow is sequentially positioned at main air compressor after multi-stage air compressor, such as double stage compressor, three-stage air compressor etc..Every one-level air compressor of rear class air compressor is respectively coaxially connected by aerostatic bearing with a turbo-expander.
Further, described air compressor unit is 2-5 level.
Further, also include that water separator, described water separator are connected with turbo-expander.
In such scheme, its operation principle is: high-speed electric expreess locomotive drives main air compressor operation, air is sucked by air compressor unit and is compressed into high temperature and high pressure gas, high temperature and high pressure gas enters back into the rear class compressor driven by turbo-expander expansion work and compresses further, heat is passed to cooling water in outdoor heat exchanger by the High Temperature High Pressure air discharged, High Temperature High Pressure air themperature reduces, cooling water temperature raises and is collected in water tank for life, in high pressure after heat exchanger is lowered the temperature, warm air enters back into the interior energy of turbo-expander adiabatic expansion acting consumed cabin air itself, temperature is reduced to cryogenic temperature, pressure drops to atmospheric pressure, heat in room absorption chamber it is sent directly into after being removed water by water separator, make indoor temperature be gradually lowered and reach purpose of freezing.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
(1) directly use air to make cold-producing medium, destruction to atmospheric environment, beneficially energy-saving and emission-reduction have been reduced or avoided.
(2) because of compressed air adiabatic expansion acting in turbo-expander, the rear class air compressor of the air compressor unit coaxial with decompressor is utilized to reclaim expansion work as its power resources.The high speed rotating of decompressor impeller can drive rear class compressor high speed rotating, it is possible to the compressed air needed for acquisition system, effectively reduces motor load and power consumption, improves refrigerating efficiency, and there is not the problem that starting current is big, can protect motor.
(3) rear class compressor uses pressure-feed air bearing to be connected as base bearing with turbo-expander, by importing compressed air at operation process middle (center) bearing intracavity, main shaft is made to be suspended in compressed air, the speed of mainshaft can be at 50000-100000r/min, thus air centrifugal type efficient compression in rear class compressor can be made, owing to being air bearing, the ratio of viscosities lubricating oil of air is much smaller, therefore the frictional heat using air bearing to produce is the least, corresponding power loss is also few, and turbo-expander volume is little, lightweight, efficiency is high, noise is little, energy saving, easy to operate, the duration of runs is long, oil-free pollution etc., thus be used widely.
(4) simple and reasonable, owing to cold-producing medium is air, easy to connect, it is not necessary to worry that system refrigerant is revealed and pollutes the problems such as environment.
(5) tap water of cooling heat exchanger compressed air is after being heated by high-temperature hot air, is collected in water tank for life.
