In comparison with the prior art, one refrigeration compressor is reduced, the size and the weight can be effectively reduced, the carrying is convenient, the occupied space is small, purposes of material conservation, energy conservation, convenience for vehicle mounting and the like can be achieved, the effects are good, and the temperature sensor calibration device can be particularly applied to detection of the temperature sensor in the vehicle refrigeration system.
Description
Technical field
The utility model relates to a kind of temperature sensor calibrating installation.
Background technology
Existing temperature calibrating installation is all to examine and determine for certain specific temperature sensor, mainly contain two class calibrating installations, a kind of is temperature calibrating groove, a kind of is temperature calibrating case, temperature calibrating groove belongs to liquid simulation, for the calibrating of contact type temperature sensor, such as resistance-type, thermocouple temperature sensor etc.; Temperature calibrating case belongs to gaseous state simulation, for the calibrating of non-contact temperature sensor, is for example mainly, by the calibrating of the temperature sensor of heat radiation, convection current conduction heat, infrared temperature-test sensor.Because above-mentioned unit dedicated temperature sensor calibrating installation is when detecting, a calibrating installation needs a compressor, while going out to examine and determine, need to carry many different calibrating installations simultaneously, volume is larger, be inconvenient to carry, this brings a lot of inconvenience to work, and unit dedicated temperature sensor calibrating installation energy consumption is also larger simultaneously.
Utility model content
Technical problem to be solved in the utility model is to provide and can meets different temperatures sensor calibrating use, a kind of temperature sensor calibrating installation simple in structure, easy to carry, area occupied is little.
The technical solution adopted in the utility model is as follows:
A kind of temperature sensor calibrating installation, it is characterized in that: it comprises housing, is arranged on temperature calibrating groove and temperature calibrating case and a refrigeration compressor being connected with temperature calibrating case with described temperature calibrating groove respectively in described housing, described refrigeration compressor is arranged at the bottom of housing, and described outside is provided with for controlling the controller of temperature calibrating groove and temperature calibrating case.
In the refrigerating plant of described temperature calibrating groove and described temperature calibrating case, be provided with evaporator, the position of described evaporator is higher than described refrigeration compressor.
Described refrigeration compressor is underlying horizontal compressor, and model is HQX-23.
Described refrigeration compressor is provided with variable-frequency power sources.
Good effect of the present utility model is as follows: the utility model is examined and determine temperature the composite design of groove and temperature calibrating case, and be used in conjunction with a refrigeration compressor and can meet different tested temperature sensors simultaneously and use, the utility model has compared with prior art reduced by a refrigeration compressor, can effectively reduce volume and weight, easy to carry, area occupied is little, can reach and save material, energy-conservation simultaneously, be convenient to the purposes such as vehicle-mounted, particularly be applied to the detection of the temperature sensor in the refrigeration system in automobile, effect is very good.
In the refrigerating plant of temperature calibrating groove and temperature calibrating case, the position of evaporator is higher than refrigeration compressor, can be so that cryogenic gas declines in device, high-temperature gas rises, and the homogenising more of temperature in device reduces frosting, freezes, dewfall is on the device impact in serviceable life.
Described refrigeration compressor is provided with variable-frequency power sources, makes by high-frequency, to turn round in temperature-fall period when device, and the constant temperature stage, with low frequency running, reduces the refrigerating capacity of refrigeration system, with saves energy, can also improve the performance of calibrating.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
In the accompanying drawings: 1 temperature calibrating groove, 2 temperature calibrating casees, 3 refrigeration compressors, 4 controllers, 5 housings.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1, the utility model comprises housing 5, the temperature calibrating groove 1 being arranged in housing 5 is examined and determine case 2 with temperature and is arranged on the refrigeration compressor 3 that housing 5 bottoms are connected with temperature calibrating case 2 with temperature calibrating groove 1 respectively, described refrigeration compressor 3 is connected with the refrigerating plant of temperature calibrating case 2 with temperature calibrating groove 1, described housing 5 is externally connected with controller 4, controller 4 is provided with control knob, display device, be convenient to the control operation of this calibrating installation, for different temperature sensors, examine and determine operation, during operation, by the control knob on controller 4, can only enable temperature calibrating groove 1 or only enable temperature calibrating case 2, in the display device of controller 4, show the temperature of calibrating installation simultaneously.The model of described controller 4 adopts Korea S ternary TEMI300, or the controller that adopts Huzhou JNBO Electronics Technique Co., Ltd. to produce, and meets request for utilization.
In the refrigerating plant of temperature calibrating groove 1 and temperature calibrating case 2, be provided with evaporator, the position of described evaporator is higher than refrigeration compressor 3, described refrigeration compressor 3 adopts underlying horizontal compressor, the HQX-23 type compressor that its model adopts Huzhou JNBO Electronics Technique Co., Ltd. to produce.Refrigeration compressor 3 is with variable-frequency power sources, make by high-frequency, to turn round in temperature-fall period when device, the constant temperature stage turns round by low frequency, reduce the refrigerating capacity of refrigeration system, with saves energy, can also improve the performance of calibrating, and add pressure of inspiration(Pi) limiting valve on the air intake duct of refrigeration compressor 3, protect refrigeration compressor nonoverload, improve the reliability of device.The utility model can effectively reduce volume and weight, saves material, energy-conservation, is convenient to the purposes such as vehicle-mounted.
Above specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make to the present embodiment the modification that there is no creative contribution as required after reading this instructions, but as long as within the scope of claim of the present utility model, are all subject to the protection of Patent Law.
