Detailed description of the invention
Below by embodiment, and 1-6b by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.In the description, same or analogous drawing reference numeral indicates same or analogous parts.The explanation of following reference accompanying drawing to embodiment of the present invention is intended to make an explanation to present general inventive concept of the present invention, and not should be understood to one restriction of the present invention.
In the fields such as HVAC, air conditioning for automobiles, refrigeration and transport, temperature-sensitive bag is installed usually on the such as heat exchanger device such as evaporimeter or condenser or product and carrys out real-time measuring tempeature.
Operation principle and the effect of temperature-sensitive bag will be illustrated below.
The operation principle of temperature-sensitive bag utilizes the temperature variant rule of the various physical property of material to be usable output signal temperature transition, pilot controller work.Temperature-sensitive package gripper is in its erecting device, and temperature-sensitive bag senses temperature in heat exchanger tube by the main part of this erecting device or insertion section heat transfer, is converted into exportable signal, is transferred to controller.
The effect of temperature-sensitive bag is mainly manifested in following several respects (general conventional control flow):
1, in cooling mode, compressor is protected.
The open and close controlling compressor and outer blower fan run.
2, in a heating mode, there is anti-cold wind, blow the function of waste heat and controlled wind speed.
According to the temperature of test, control inner blower and open or close and wind speed; Prevent blowing a cold wind over and waste heat.
3, in a heating mode, high temperature protection function is had.
During heating operation, if the temperature measured is higher, stop outer blower fan work; If this temperature continues to raise again, stop compressor operating.
4, in a heating mode, the unlatching of auxiliary electrical heater is controlled.
When the temperature measured is lower, then compressor start, the running of outer blower fan, reversal valve obtain electric, indoor fan and open, and auxiliary electrical heater is opened.When this temperature reaches certain value, auxiliary electrical heater is closed.
Find out thus, temperature-sensitive wraps in whole control system and plays very large effect, is the vitals in air-conditioner control system.If its installation and placement location is bad even comes off, cause the surface temperature measurement of the device such as evaporimeter or condenser inaccurate, directly have influence on the work of air-conditioner control system.
Not all fine based on the temperature-sensitive bag mounting means used in current industry, quick not and firmly, so be necessary to be optimized design to this device.
See Fig. 1 and 2, it illustrates according to heat exchanger 100 of the present invention.Particularly, temperature-sensitive bag 60 is fixed to described heat exchanger 100 by temperature-sensitive bag erecting device 50 of the present invention.
