Description
Technical field
The utility model belongs to the air-conditioner technology, particularly a kind of room air conditioner.
Background technology
By 2011, the existing civil buildings total amount of China is 40,000,000,000 square meters, annual newly-built civil buildings 2,000,000,000 square meters, room air conditioner is the main air-conditioning equipment that China's residential housing and the following public building of construction area 20000 square meters adopt at present, China is as major country of production's annual production of world's room air conditioner more than 1,400 ten thousand, and with average annual 28.8% speed sustainable growth, therefore further improve the pattern of room air conditioner, promote the critical component performance, it is moved in energy-efficient mode China's building field enforcement energy-saving and emission-reduction work is had significant impetus.The core component of room air conditioner is compressor, condenser, evaporimeter and throttle mechanism, and wherein condenser is a vitals that influences factors such as performance, power consumption, appearance and size, weight and cost.Therefore, Japan and other countries and China recent years constantly are devoted to improve the work of room air conditioner heat exchange property, because of the convection transfer rate of air side more much smaller than the coefficient of heat transfer of refrigerant side evaporation, condensation, like this in the exchange heat process, air side can form bottleneck, so the reinforcement of condenser air side exchange capability of heat is the focus of research and equipment improvement always.The aluminium fin of heat exchanger copper pipe overcoat, what use in early days all is plain film, and heat exchange efficiency is lower, is modified into corrugated fin later in 1973, and exothermic coefficient is brought up to 1.2 times of plain film approximately.Worked being modified into single face crack sheet in 1979, exothermic coefficient is brought up to 1.65 times of plain film.This is because thickening of air laminar boundary layer destroyed in the crack, and exothermic coefficient is improved.Nineteen eighty-two rises, and is modified into two-sided crack sheet again, makes the exothermic coefficient of air side bring up to 1.85 times of plain film.Copper pipe is improved to the 7mm pipe after 2000, and the exchange capability of heat of calking sheet is brought up to 2.5～3 times of plain film.Present two-sided calking sheet is still main heat exchange fin form, and form is still in updating.But adopt the air-conditioner condensation temperature after Air-cooled Condenser is handled still higher, depend on the air themperature of place environment, can't further improve compressor operating efficient; And the air drag of the sheet of charging is bigger, for reaching condensation effect preferably, needs than powerful fan; The air thermal capacitance is less, and the required heat exchange area that facings the wind is also bigger.Cause the required metal consumption of equipment and equipment energy consumption excessive.
In recent years both at home and abroad research institution and equipment vendors in the research aspect refrigeration, the used condenser of air-conditioning system with improve and mainly concentrate on the central air-conditioning unit and be equipped with on the condenser, proposed to improve the several different methods of water cooled condenser, made tube side fluid produce to rotate with the method for optimizing structure such as disturbance, adopt enhanced heat transfer component to improve condensing heat exchanger cast method, adopt novel alloy material or coating to improve heat exchanger tube surface nature method, adopt evaporating heat exchanger as condenser etc. as adopting the distortion runner.The condenser that also has part Study and patent to propose room air conditioner adopts water-cooled heat exchangers such as fountain.Though adopt water cooled condenser can reduce condensation temperature 20% in theory, but room air conditioner adopts water cooled condenser replaces air cooled condenser still to have the actual motion problem, the one, when air-conditioner when China's hot summer and warm winter zone, gentle district work or outdoor environment humidity are big, adopt water cooled condenser will significantly reduce service behaviour separately, condenser working efficient and the condensation temperature range of decrease all are starkly lower than Air-cooled Condenser under this operating mode; The 2nd, air-conditioner reliably working continuously when working as outdoor temperature winter and being lower than 4 ℃; The 3rd, lost many advantages of Air-cooled Condenser, as can the different periods coolings and heat supply simultaneously, adaptation outdoor environment parameter more wide in range etc.; The 4th, many improvement are primarily aimed at the large-size air conditioning system, the central air-conditioning unit is equipped with on the condenser, Shang Weijian is about setting up cooling tower, have the high-efficiency compact design, all can move in 6000kW, summer in winter and the room air conditioner of simultaneous air-conditioning and the relevant report of optimal control method thereof to be applicable to that refrigerating capacity, heating capacity are lower than.
Summary of the invention
The utility model is not high at present room air conditioner efficient, the environment applicability is not strong, water-saving result is bad and pipe row's metal consumption and the high deficiency of equipment power dissipation, has proposed a kind of room air conditioner.
A kind of room air conditioner, this room air conditioner is made up of with valve and the conduit of air conditioner condensation heat exchanger 3, expansion gear 4, Air-cooled Condenser 5, four-way change-over valve 6, evaporimeter 7, setting quantity compressor 1, gas-liquid separator 2, family, wherein,
Described compressor 1 one ends link to each other with the end of family with air conditioner condensation heat exchanger 3 through second magnetic valve 9 by conduit, and the other end of described compressor 1 links to each other with the 3rd pin 18 of four-way change-over valve 6 through gas-liquid separator 2 by pipeline;
Described family links to each other with first pin 16 of four-way change-over valve 6 through the 3rd magnetic valve 10 by pipeline with the other end of air conditioner condensation heat exchanger 3;
The other end of described evaporimeter 7 links to each other with an end of Air-cooled Condenser 5 through the 5th magnetic valve 12, expansion gear 4 and the 7th magnetic valve 14 by conduit;
The described air but other end of formula condenser 5 links to each other with the 4th pin 19 of four-way change-over valve 6 through the 4th magnetic valve 11 by conduit;
Described the 4th magnetic valve 11, Air-cooled Condenser 5 and the 5th magnetic valve 12 are in parallel by conduit with the 6th magnetic valve 13;
Described the 3rd magnetic valve 10, family usefulness air conditioner condensation heat exchanger 3 and second magnetic valve 9 are in parallel by conduit with first magnetic valve 8;
Described evaporimeter 7 and the 7th magnetic valve 14 are in parallel by conduit with the 8th magnetic valve 15 by conduit.
The beneficial effects of the utility model: compact conformation of the present utility model, energy-efficient, be applicable to that refrigerating capacity, heating capacity are lower than 6000kW, all need summer in winter the room of reliability service and simultaneous air-conditioning to adopt.By improving condenser system, can be less in outdoor environment humidity, stable operation has the more wide in range characteristics of the outdoor environment parameter of adaptation under the situation that humidity is bigger.Thereby and significantly improve the coefficient of performance and realize energy-conservation by reducing the air conditioner condensation temperature.The energy-conservation 20%-40% of common room air conditioner with respect to identical refrigerating capacity, heating capacity; Long-time running has the water-saving effect, and theory water consumption is the 5-10% of general water cooled condenser; Under the prerequisite of identical condensing heat-exchange amount, metal consumption significantly reduces, and the heat exchange efficiency height improves equipment economy, reliability and service life.
