Description
Technical field
The utility model relates to refrigeration and air-conditioning technical field, especially a kind of direct refrigeration-type magnetic suspension inverter air conditioner
Group.
Background technique
Energy-saving and emission-reduction be China " 13 " during grand strategy, in refrigerating and air conditioning industry, large public building air-conditioning
The half or so of the total electric energy of electric energy Zhan of consumption.Therefore, the energy consumption for saving air-conditioning equipment has a very important significance.
Currently, in the ventilation and air conditioning system in large public building space, frequently with water cooler+air-conditioning box end shape
Formula carries out cool-down dehumidification.Referring to Fig. 1, this system includes the compressor 1 for being in turn connected to form loop, shell and tube condenser 2, section
Flow device 3, shell-tube evaporator 4 and air-conditioning box 6.The heat of shell and tube condenser 2 is discharged to outdoor through cooling tower 7, and compressor 1 uses
Screw compressor, air-conditioning box 6 from bottom to up successively include wind inlet section, fillter section, cooling section and air supply section, air-conditioning box 6 it is cold
But section is equipped with surface air cooler, and air supply section is equipped with centrifugal blower.Shell-tube evaporator 4 is cold by chilled water system and the table in air-conditioning box 6
Device is connected, and return air (outdoor air or mixing air), by cool-down dehumidification, is sent out in surface air cooler by centrifugal blower.Condensation
Heat in device 2 is discharged in outdoor environment by cooling water system by cooling tower 7.Above system pipeline flowing is complicated, chilled water
System varying duty regulating power is poor.Meanwhile the pipeline water cooler sub-load efficiency is low, causes system in entire air-conditioning season
For comprehensive energy efficiency than low, operating cost is high when operation.
Summary of the invention
Above-mentioned water cooler in the prior art there are aiming at the problem that, the purpose of the utility model is to provide a kind of directly systems
Cold type magnetic suspension convertible frequency air-conditioner unit.It can change progress flexible modulation according to building loading and improve refrigeration system
Efficiency, simplied system structure, save air-conditioning system operating cost.
In order to achieve the above object of the invention, the technical solution of the utility model is realized as follows:
Direct refrigeration-type magnetic suspension convertible frequency air-conditioner unit, it includes that the compressor for being in turn connected to form loop, shell-tube type are cold
Condenser, throttling set and air-conditioning box.The heat of the shell and tube condenser is discharged to outdoor through cooling tower, air-conditioning box from bottom to up according to
Secondary includes wind inlet section, fillter section, cooling section and air supply section.It is structurally characterized in that the compressor is centrifuged using magnetic suspension frequency conversion
Compressor, the cooling section of air-conditioning box are equipped with direct-evaporation-type heat exchanger, and the air supply section of air-conditioning box is equipped with frequency conversion centrifugal blower.
The utility model is due to the above structure, with direct-evaporation-type heat exchanger instead of package in the prior art
Evaporator and surface air cooler, while using magnetic suspension frequency conversion centrifugal compressor instead of screw compressor in the prior art.Together
The prior art is compared, the beneficial effects of the utility model are:
(1) the oil-free frequency conversion centrifugal compressor of magnetic suspension is used, refrigeration system is succinct, without complicated oil piping system, operational safety
Reliably.
(2) shell-tube evaporator in the prior art is eliminated, initial cost is reduced, while reducing the energy of chilled water conveying
Consumption.
(3) compressor and air supply section blower all use DC frequency-changing control technology, sub-load flexible adjustment, and unit is comprehensive
It is higher to close Energy Efficiency Ratio.
The utility model is described further with reference to the accompanying drawings and detailed description.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of air-conditioner set in the prior art；
Fig. 2 is the structural schematic diagram of the utility model air-conditioner set.
Specific embodiment
Referring to Fig. 2, the direct refrigeration-type magnetic suspension convertible frequency air-conditioner unit of the utility model includes being in turn connected to form loop
Compressor 1, shell and tube condenser 2, throttling set 3 and air-conditioning box 6.The heat of shell and tube condenser 2 is discharged to room through cooling tower 7
Outside, compressor 1 uses magnetic suspension frequency conversion centrifugal compressor.Air-conditioning box 6 successively includes wind inlet section, fillter section, cooling from bottom to up
Section and air supply section, the cooling section of air-conditioning box 6 are equipped with direct-evaporation-type heat exchanger, and air supply section is equipped with frequency conversion centrifugal blower.
When the utility model unit works, return air (outdoor air or mixing air) enters from 6 wind inlet section of air-conditioning box,
Enter cooling section after the purified processing of fillter section, the refrigerant in air and direct-evaporation-type heat exchanger directly carries out hot friendship
It changes.Air is sent out in air supply section by frequency conversion centrifugal blower by after cool-down dehumidification.Heat in condenser 2 passes through cooling water system
System is discharged in outdoor environment by cooling tower 7.
