Detailed description of the invention
Fig. 1 shows an embodiment of the refrigeration system of the present invention.Wherein, refrigeration system 100 has electric control gear 190, and electric control gear 190 includes housing 192 and the electronic device 191 being arranged in housing 192, and it is used for providing for the various operations of refrigeration system 100 controlling.
Refrigeration system 100 also has a refrigerating circuit of conventional components, the compressor 110 that is i.e. sequentially connected with by pipeline, condenser 120, vaporizer 130, electromagnetic valve 140, expansion gear 150.Wherein, electromagnetic valve 140 can be used in controlling the opening and closing in loop and providing partial throttling effect to cold-producing medium；Expansion gear 150 is then mainly used in providing throttling action, and it can be to have the capillary tube of fixed restriction effect or have the electric expansion valve of scalable restriction effect, or other can be used for the device of throttling.Additionally, refrigeration system 100 also includes the electronic component cooling device 160 being connected between electromagnetic valve 140 and vaporizer 130, it is used for cooling electronic device and reduces the humidity of its local environment.Electronic component cooling device 160 separates with electronic device 191 in housing 192 to be arranged, to realize cooling down the air in electronic device and housing 192 or other parts in the lump simultaneously.
Electronic component cooling device 160 includes air-refrigerant heat exchanger 161 and blower fan 162, is realized the forced-convection heat transfer of wind and the cold-producing medium in heat exchanger 161 by blower fan 162.Wherein, the heat exchanger 161 in electronic component cooling device 160 can use general design of heat exchanger mode, such as, designed the specifications parameter of heat exchanger 161 by the caloric value of electronic device.Compared with the electronic device cooling mode of existing routine, the structure of electronic component cooling device 160 of the present invention and the type of cooling of employing thereof bring more preferable cooling effect for comparing conventional direct ventilating and cooling, and Comparatively speaking bring more preferable equipment dependability with conventional cooling by water, the problem leaked without existence and cause electronic device generation potential safety hazard.
Owing to above-mentioned heat exchanger inevitably will produce condensed water during cool-down dehumidification.Therefore, in order to focus on condensed water, can be at electronic component cooling device 160 arranged beneath drip tray 170.Certainly, drip tray 170 also can substitute with the condensed water collecting device of other form.
For optimizing the topology layout in electric control gear 190, each parts of reasonable Arrangement are to improve space availability ratio.Electronic component cooling device 160 in the present embodiment may be arranged at below the housing 192 of electric control gear 190, and the disposed inboard drip tray 170 below housing 192, and make it just be arranged in below heat exchanger 161, to receive issuable condensed water on heat exchanger 161 fin.
Preferably, for the ambient humidity in hands-free high housing 192, by condensate drain 180, condensed water can be drawn housing 192 and outward and process.Alternatively, condensate drain 180 includes: be connected to bottom drip tray 170 for the drain pipe 182 drawn from drip tray 170 by condensed water；And be arranged in outside housing 192, and for receiving the water tank 181 of the condensed water that drain pipe 182 is derived, in order to condensed water is focused on.
Alternatively, electromagnetic valve 140 and expansion gear 150 can be directly arranged in housing 192, to avoid the parts layout outside electric control gear the compactest.
Additionally, run refrigeration system 100 for cooling down the opportunity of electric control gear 190 and holding the control of the aperture to expansion gear for better controling over.Present invention additionally comprises and be arranged on temperature sensor and/or humidity sensor in electric control gear 190, thus control opening and closing and the action of expansion gear of electromagnetic valve 140 according to the temperature index in electric control gear 190 and/or humidity index.
This set refrigeration system will obtain more preferable effect when being applied to large-scale refrigeration unit (such as, centrifugal chiller or Screw chiller).This is because, this type of electric control gear 190 in conventional operation to the cooling requirement of caloric value generally between 3kW-5kW, this only occupies the least ratio for the refrigerating capacity of large-scale refrigeration unit hundreds if not thousands of standard tons easily.Therefore, this electronic component cooling device 160 of connecting in the refrigeration system of large-scale refrigeration unit impacts essentially without to the work of former refrigeration system.
Above-described embodiment will be combined to describe the work process of the present invention as follows.When the temperature in the housing 192 electric control gear 190 being detected and/or humidity index are higher than certain value, open electromagnetic valve 140, the cold-producing medium now cooled down through condenser 130 and expand through electromagnetic valve 140 and expansion gear 150 flows through air-refrigerant heat exchanger 161, and carries out heat exchange with the air stream blowed by blower fan 162.Cooled air stream flows in whole housing 192, so not only achieve the cooling to electronic device 191 and dehumidifying, to the ambient temperature in whole housing 192 and the regulation of humidity and control in also realizing in its convection process, effectively reach the environment in electronic device 191 and housing 192 is lowered the temperature, and by its humid control below threshold value.
Wherein, it is appreciated that, in the present embodiment, the cooling to electric control gear 190 need to be carried out with the operation of corresponding refrigeration system simultaneously.This is owing to electronic component cooling device 160 is connected in this set refrigeration system, and can be uniformly controlled the break-make of refrigerating circuit by electromagnetic valve 140.This kind of design, on the one hand simplifies the complexity of refrigerating circuit and the complexity to the control method that electric control gear 190 cools down, is greatly improved equipment dependability；On the other hand by directly applying the sub-fraction cold entrained by the cold-producing medium in main refrigerating circuit to cool down, not only bringing more more preferable cooling effect than conventional chilling mode, the work on main refrigerating circuit self produces any impact the most hardly.Comprehensively achieve and improve cooling effect, raising equipment dependability, reduction system complexity etc..
Present invention also offers the embodiment of the cooling means of the electric control gear of the refrigeration system of a kind of correspondence.Such as, when this system is controlled with temperature, during ambient temperature signal in the master controller of centrifuge refrigeration system receives the housing 192 of electric control gear 190, it is compared with built-in preset temperature, if it is more than preset temperature, then output control signal carrys out the blower fan 162 in opens solenoid valve 140 and electronic component cooling device 160.Now；After cold-producing medium is throttled by the electromagnetic valve 140 expanded device 150 opened, it is passed to electronic cooler 160, heat exchange is carried out with the air flowing through heat exchanger 161 under blower fan driving, and and then improve the ambient temperature in whole housing 192, it is made to maintain below preset temperature, it is to avoid electric control gear is overheated.
In addition, when this system is controlled based on both temperature and humidity, when ambient temperature in the master controller of centrifuge refrigeration system receives the housing 192 of electric control gear 190 and ambient humidity signal, calculate dew point temperature corresponding under this relative ambient humidity, and it is compared with the ambient temperature detected: if the dew point temperature calculated is less than ambient temperature, then output control signal carrys out the blower fan 162 in opens solenoid valve 140 and electronic component cooling device 160.Now；After cold-producing medium is throttled by the electromagnetic valve 140 expanded device 150 opened, it is passed to electronic cooler 160, heat exchange is carried out with the air flowing through heat exchanger 161 under blower fan driving, and and then improve the ambient temperature in whole housing 192, it is made to maintain more than dew point temperature, avoid electric control gear overly moist and condensation, and then avoid it to lose efficacy；If the dew point temperature calculated is greater than or equal to the ambient temperature detected, then output alarm signal or protection signal are reminded user or directly close the blower fan 162 in described electromagnetic valve 140, described electronic component cooling device 160 and the compressor main circuit in refrigerating circuit.
