Background technology
Central air conditioner system purifies the process such as (or purifying), cooling (or heating), humidification (or dehumidifying) in the mode concentrated or partly concentrate to air, thus a whole set of air-conditioning system of environment needed for life or production technology standard is provided, generally include Central air-conditioning unit (main frame), air-treatment end-equipment, air-line system, water system and control system five major part, its technology barriers mainly concentrate on host machine part, and therefore main frame manufacturer also just becomes the absolute leader of central air-conditioning industry.
Central air-conditioning has multiple mode classification, fluorine system can be divided into by cold (heat) source carrier and refrigerant, water system two kinds, can be divided into centralized by airhandling equipment distribution, half centralized and distributing three kinds, can be divided into closed by the air source of central system, single flow and hybrid three kinds, full air can be divided into by the medium of burden indoor heat load, Quan Shui, air and water and cryogen four kinds, handpiece Water Chilling Units (centrifuge is then comprised by Host Type, air-cooled screw machine, water-cooling screw rod machine, lithium bromide chiller, water earth source heat pump unit, module machine), refrigerant variable-flow unit (connected machine, digital vortex multi-connected machine), unit machine and end etc., from products application angle, central air-conditioning can be divided into Centralized Air-conditioning in Public Buildings, residential central air conditioning.
Central air-conditioning has gone through over one hundred year at European & American Market, market enters the stage of ripeness already, but China's Market of Central Air-conditioning from the eighties in last century just to be entered by foreign capitals brand and public building rises and obtains initial development, thereafter along with the fast development of economy and the rapid growth of commercial real estate, domestic Market of Central Air-conditioning really enters Fast growth phase, 2003-2013 during 11 years domestic Market of Central Air-conditioning scale rise to 64,400,000,000 yuan from 8,500,000,000 yuan, CAGR reaches 22.45%.
From market segments aspect, as central air-conditioning traditional market, Centralized Air-conditioning in Public Buildings is widely used in all kinds of public building and the industrial refrigeration places such as office building, market, rail friendship, airport, hospital, becomes domestic Market of Central Air-conditioning dominance strength; Meanwhile, along with the lasting lifting of consumption of resident ability, also discharged fast based on the residential central air conditioning demand of multi-connected machine, unit machine.
It is reported, the large central air-conditioning products house house ornamentation demand accounting of current multi-connected machine, unit machine (mainly air-cooled ducted air conditioner) two is respectively 40%, about 60%, and multi-connected machine, unit machine total occupies overall household application market 95% share (separately having 5% family formula miniature water machine), according to central air-conditioning sales data, roughly extrapolate current residential central air conditioning market scale and be about 18,000,000,000 yuan, Centralized Air-conditioning in Public Buildings market scale is about 48,000,000,000 yuan.
And according to product type, multi-connected machine, unit machine and large-scale water machine (centrifuge, screw machine) are in occupation of domestic market leading position, within 2013, three's sales volume adds up to accounting to reach 74.4%, wherein multi-connected machine, unit machine are the core forces of medium and small cold central air-conditioning, except towards middle-size and small-size business market, its in household application market especially in occupation of leading position; The refrigerating capacity advantage that large-scale water machine then can not be substituted with it dominates large commercial market all the time, and becomes the wind vane in whole Centralized Air-conditioning in Public Buildings market.
Technical field of central air presents pluralistic trend in recent years, and the technique directions such as frequency conversion, environmental protection, comfortableization, intellectuality, energy-saving constantly occur, it has driven product structure to upgrade further on the one hand, improves enterprise getting profit space; Also provide more more options for forming differential competition between brand on the other hand, the converter technique of such as domestic-investment brand in large-scale water machine field is promoted and has been obtained very good effect; Consider that the accounting of central air-conditioning in building energy consumption is still higher, under energy-saving main trend background, estimate that following central air-conditioning is that the theme of core still can not change with power-saving technology, the competitiveness of product will focus on energy saving aspect for a long time.
What require life, comfortable working environment along with the strict demand of industrial technology quality and people improves constantly, and the domestic demand to central air-conditioning is also by steady growth.Current central air-conditioning, except except original industrial circle and commercial kitchen area, has started to apply to residential quarters, has realized central heating and cooling.
Central air-conditioning mainly regulates and controls the temperature of indoor, realizes the state of constant temperature, and the production of people and living environment can be allowed more comfortable.Central air-conditioning is air in buildings and thermoregulator dedicated system, mainly by the switch of the equipment such as valve, blower fan, comes the temperature in conditioning chamber and air humidity, can reach winter heating, the effect of cooling in summer.Central air-conditioning is formed primarily of a series of system in combination such as compressor, water circulation system, cooling system, fan coil.The controller of central air-conditioning is that traditional contact controller controls relay and digital display circuit a long time ago, controlling functions is too easy, and can not carry out the real-time control of networking, control effects very bad, lack flexibility, can not the various parameters of monitoring control system in real time.Along with the continuous growth of China's economy and the raising of scientific and technological level, heavy construction construction project gets more and more, and central air-conditioning is widely used.But cause control effects poor because operating energy loss is unreasonable, the energy consumption of central air conditioner system remains high, and have impact on the performance of building performance always.
