Description
Technical field
The present invention is relevant for a kind of demisting energy-saving control device with temperature-compensating adjustment, espespecially a kind of carrying out revised setting value or contains the mist measured value according to varying environment at any time, make and detect the mist value and not affected by different temperature range occasions, make the demist action can more meet the execute-in-place condition, avoid producing the demisting energy-saving control device of demist misoperation on opportunity.
Background technology
In traditional refrigerating equipment, demister is generally round-the-clock unlatching in 24 hours, although demister can be down to the degree that the phenomenon that hazes occurs minimum, but produced also new electric power and expended problem, extra power consumption will be to avoid, these extra electricity charge for general shop, representative be the increase of cost of business operation.But in fact, 24 hours round-the-clock unlatching demisters are not to be best defogging method, because under most situation, especially when not opening glass door for a long time, the generation frequency of the phenomenon that hazes is lower, this is also representing most demist action is non-essential, and demist power consumption belongs to waste.And in order to reduce the waste of this electric power, it is better method that the demist electricity saver is installed.
Present demist electricity saver applicable situation relatively is partial to the place with ring control, for example: supermarket or super merchant, but because being subjected to environment temperature to cause measured value drift result, place (as: fruit shop) or larger place (as: chafing dish restaurant) effect of the temperature difference for not ring control can be influential, therefore, the demist electricity saver being done that measured value or pre-set parameter revise do temperature-compensating is a kind of mode of improving this ambient temperature effect.
For known patent, such as TaiWan, China patent announcement M258270 number " demister for glass door of refrigerating equipment ", the tradition demisting controlling device is when humidity changes to some extent, medium coefficient of discharge between copper sheet also will change thereupon, so the capacitance of sensory panel will be different along with the variation of humidity.Therefore, the characteristic that the capacitance on this patent utilization sensory panel can change along with different humidity, thereby the output concussion frequency of change circuit.Output concussion frequency is delivered in the microprocessor after amplifying via a transistor, microprocessor can calculate via received frequency present wetness, and then understand the generation whether glass door on the present refrigerating equipment has the phenomenon of hazing, to determine whether will open demister; Only this patent is not suitable for the place use that environmental change is large, the temperature difference is large, is only suitable for having the place of ring control, and must adds the equipment of monitoring of environmental
No. the 197855th, TaiWan, China patent announcement " power conservation type demisting controlling device " and for example, this patent gets reading with the surface temperature of palpus demist object through the detecting instrumentation, and utilize the air of object outside to do, wet-bulb temperature detecting instrumentation must be done, the signals such as wet-bulb temperature reading are delivered to electronic type and are calculated comparator, calculate control temperature in surface after dew-point temperature is obtained in computing in electronic type is calculated comparator, just the real surface temperature with body surface compares, when the real surface temperature is controlled temperature greater than the surface, just calculate comparator output signal by electronic type, namely do not drive control relay and make the heater heating; Only this patent is only applicable to the dew point type and detects the mist sensing component, and not temperature compensated function.
As for TaiWan, China patent announcement No. 353850 " automatic calibration temperature controller " and disclose patents such as " but accurate temperature inductors of tool automatic programming adjustment " No. 200641337, although relate to temperature control technology, but do not have relatedly with the demist technical field, can't solve any problem relevant with demist yet.
Summary of the invention
Because the disappearance of known technology, the present invention proposes a kind of demisting energy-saving control device that temperature-compensating is adjusted that has, can carry out revising setting value or containing the mist measured value according to varying environment at any time, make and detect the mist value and not affected by different temperature range occasions, make the demist action can more meet the execute-in-place condition, avoid producing demist misoperation on opportunity.
For achieving the above object, the present invention proposes a kind of demisting energy-saving control device that temperature-compensating is adjusted that has, and comprises:
