Description
Technical field
The utility model belongs to building energy conservation device scope, the energy-saving fan coil units of particularly a kind of super low noise.
Background technology
The energy-conservation charcoal that subtracts is that the our times various countries the most urgently face and severe problem; It also is the maximum problem that following enterprises face promotes the management performance.In the whole living environment of the mankind, the most relevant with mankind's activity is the energy resource consumption in the building.Even yet building general layout and purposes are different in the whole building; Various forms of energy consumption accountings also thereby different; But the total energy consumption of HVAC accounts for whole building total energy consumption all about 45-55%, so each enterprise all must focus on the link of heating ventilation air-conditioning system energy consumption in the energy-conservation focus of building.In whole heating ventilation air-conditioning system if do not add the energy consumption of meter boiler electric heating station monitoring system; Each equipment energy consumption accounting of whole heating ventilation air-conditioning system approximately is refrigerator 76%, cooling tower 2%, cooling water pump 6%, chilled water pump 5%, regional water pump 3%, and terminal fan coil or wind cabinet only account for 8%.Therefore the heating and ventilating discipline engineer and the owner of the overwhelming majority can be main with refrigeration station all in the energy conservation of heating ventilation air-conditioning system, ignore the energy consumption link to terminal fan coil or wind cabinet.But; From the record of heating ventilation air-conditioning system year real-world operation energy consumption; The discovery that we are surprised very much; The year of each equipment running energy consumption has very big otherness with equipment nominal power consumption accounting in the heating ventilation air-conditioning system: refrigerator 53%, cooling tower 1%, cooling water pump 8%, chilled water pump 4%, regional water pump 6%, terminal fan coil or the accounting of wind cabinet ability loss-rate in the whole system energy consumption are but up to 28%
Can loss-rate learn by above heating ventilation air-conditioning system year running; The ratio that the power consumption of whole heating ventilation air-conditioning system is shared; The energy consumption of the main equipments such as refrigerator, refrigerating water pump, coolant pump and cooling tower of low-temperature receiver part, only account for whole central air conditioner system energy consumption 60% or more than; Terminal fan coil accounts for about 30%.
The large-scale refrigeration plant producer of Europe, U.S.A, day various countries is all changed the utensil in air-conditioning equipment energy consumption source and uses novel DC brushless electric machine by original traditional AC motor in recent years.The DC brushless electric machine is because of its mechanical property, energy transition rate exceed more than one times than AC motor and slow-speed of revolution low power consuming under still enjoy higher torsion.The energy-saving benefit of these low energy consumption is employed for a long time AC benefits that motor is beyond one's reach.Given this our company is devoted to the research and development of energy-conservation improvement of fan coil and the utilization of new DC motor for many years, through the constantly test of experiment improvement and long-term reliability, on the energy-saving efficiency of HVAC, obtains breaking through; For heating ventilation air-conditioning system backward lays the foundation on energy saving technique.
The utility model content
The purpose of the utility model is the shared ratio of power consumption to whole heating ventilation air-conditioning system, the energy consumption of the main equipments such as refrigerator, refrigerating water pump, coolant pump and cooling tower of low-temperature receiver part, only account for whole central air conditioner system energy consumption 60% or more than; Terminal fan coil accounts for the deficiency of the big energy consumption about 30% and proposes the energy-saving fan coil units of a kind of super low noise; It is characterized in that; The structure of the energy-saving fan coil units of said super low noise is in the bottom surface of air-condition heat exchanger water pond to be installed; Blower fan and DC frequency conversion controller are installed in the left side at air-condition heat exchanger, and wherein blower fan adopts the preceding bending blade centrifugal blower of two air intakes; Become wind wheel and DC brushless electric machine to assemble by preceding bending vane group.
Said air-condition heat exchanger is made up of heat exchange coil and casing, and heat exchange coil adopts the external collecting head of copper pipe stringed alumium fin to constitute.
Said copper pipe external diameter is 9.52mm, and fin thickness is 0.15～0.2mm, spacing 2.0～3.0mm.
The beneficial effect of the utility model is that the energy-saving fan coil units of this super low noise is the end-equipment of the large public building air-conditioning system independently controlled of humiture.The heat exchanger flow process realization geomantic omen adverse current of passing through to change conventional fan coil pipe unit of set heat exchange device makes the heat exchange effect reach best.The structure that changes conventional fan coil pipe unit simultaneously is to reduce noise.Secondly the unit motor adopts the DC brushless electric machine, adds microcomputerized control simultaneously, very according to environment temperature motor is carried out VFC, and temperature control system contains the arithmetic logic of PI proportional integral, can realize constant indoor temperature control.More energy-conservation than traditional AC fan coil up to more than 50%.
Description of drawings
Fig. 1 is the energy-saving fan coil units sketch map of super low noise.
Fig. 2 is the heat exchange coil structural representation.
The specific embodiment
The utility model proposes the energy-saving fan coil units of a kind of super low noise, explains below in conjunction with accompanying drawing.
Shown in Figure 1 is the energy-saving fan coil units sketch map of super low noise.Air-condition heat exchanger is made up of heat exchange coil 6 and casing 5, in the bottom surface of air-condition heat exchanger water pond 4 is installed, and on the left side of air-condition heat exchanger blower fan is installed, bending blade centrifugal blower before the two air intakes of blower fan employing; The motor 2 of blower fan is realized the frequency conversion DC control with DC frequency conversion controller 3.Heat exchange coil 6 adopts copper pipe 8 stringed alumium fins 7, and external collecting head 9 is processed (as shown in Figure 2), the wind direction adverse current of water (flow) direction and blower fan in the heat exchanger, enhanced heat exchange effect; The copper pipe external diameter is 9.52mm, and fin thickness is 0.15～0.2mm, spacing 2.0～3.0mm.。
The operation principle of fan coil cooling unit exactly by the blower fan room air that constantly circulates, makes it to be cooled or to heat through coil pipe.
The energy-saving fan coil units of the super low noise of the utility model adopts the DC brushless electric machine, adds microcomputerized control simultaneously, very according to environment temperature motor is carried out VFC.Simultaneously, since the wind direction adverse current of interior water (flow) direction of air-condition heat exchanger and blower fan, the enhanced heat exchange effect.Find out that from reality installation test result direct current digital frequency conversion fan coil is more energy-conservation up to more than 50% than traditional AC fan coil.Direct current digital frequency conversion fan coil is except reaching the energy-conservation benefit that subtracts charcoal more than 50% for the enterprise customer.Under nominal situation, generally will reach design temperature after one hour in start, unit becomes low-speed running.So we approximately can save the energy 60% with objective calculating DC fan coil and calculate, the energy-saving fan coil units of the super low noise of 100 (W) can be saved: 100 (W) x60%=60 (W)
Started shooting 10 hours every day with calculating such as certain office block, government unit, department stores, use after 1 year the energy of saving: 60W * 10Hr * 365=219000W, i.e. Hr=219 degree electricity ,=262.8 yuan of * 1.2 yuan/degree of 219 degree of can reducing expenses in a year.
