Pipeline temperature-sensitive bag 2010 does not detects.If TPipe≥TDew, then there is not condensation problem in explanation power component,
Now electromagnetic valve 2016 cuts out, variable-flow stop valve 1 and 2 all standard-sized sheets；If TPipe＜ TDew, then there is condensation in explanation power component
Problem, now electromagnetic valve 2016 is opened, variable-flow stop valve 1 standard-sized sheet, and variable-flow stop valve 2 needs to be controlled valve by mainboard
Aperture, progressively turning down variable-flow stop valve 2, controlling the coolant quantity of cooling mainboard, until guaranteeing that the temperature of power component exists
In the scope being suitable for so that TPipe≥TDew, such mainboard will depart from condensation risk.
Heating mode:
The gaseous coolant of High Temperature High Pressure discharged by compressor 201, by cross valve 202, enters vaporizer 2014 and dispels the heat,
By the rotation of inner blower 20142, indoor air is driven to pass through vaporizer 2014, with the high pressure gaseous coolant in pipeline
Carry out heat exchange, thus become the liquid coolant of middle temperature high pressure.
The liquid coolant of middle temperature high pressure, through filter 2013, enters interior organic electronic expansion valve 2012, now, interior organic electronic
Expansion valve 2012 keeps maximum opening, it is to avoid the temperature after throttling is too low, by the mainboard 302 of band heating power component module
Time, form condensation, then through filter 2011, middle temperature coolant is divided into two-way, and a road flows to the pipeline of electromagnetic valve 2016, one
Variable-flow stop valve 2 is passed through on road, flows through the heat dissipation pipeline of the mainboard 302 of band heating power component module, flows through variable-flow and cut
Only valve 1.This two-way middle temperature coolant, through filter 206, enters outer organic electronic expansion valve 2012 and throttles into low-temp low-pressure coolant, stream
Through filter 204, enter condenser 203 and carry out heat absorption evaporation, by the rotation of outer blower fan 2032, drive outdoor air to pass through
Condenser 203, carries out heat exchange with the low-temp low-pressure coolant in pipeline, thus becomes the gas coolant of low-temp low-pressure, pass through
Cross valve 202, returns to gas-liquid separator 2015, enters and returns to compressor, is formed and heats circulation.
Wherein, temperature sensor and humidity sensor detect the ambient temperature residing for power component and relative humidity, logical
Cross mainboard program and determine dew point temperature T of power component local environmentDew, pipeline temperature-sensitive bag 2010 is to power component simultaneously
Temperature T of heat dissipation pipelinePipeDetect, by contrast TDewAnd TPipeSize, it is determined that whether it exists the risk of condensation, wherein pipeline
Temperature-sensitive bag 207 does not detects.If TPipe≥TDew, then there is not condensation problem, now in explanation power component
Electromagnetic valve 2016 cuts out, variable-flow stop valve 1 and 2 all standard-sized sheets；If TPipe＜ TDew, then illustrate that power component exists condensation and asks
Topic, now electromagnetic valve 2016 is opened, variable-flow stop valve 2 standard-sized sheet, and variable-flow stop valve 1 needs to be controlled valve by mainboard
Aperture, progressively turns down variable-flow stop valve 1, controls to flow through the coolant quantity of cooling mainboard, until guaranteeing that the temperature of components and parts is suitable
In the range of conjunction so that TPipe≥TDew, such mainboard will depart from condensation risk.
In the present embodiment, the radiating mode of the mainboard of band heating power component module can be by using band radiating fin
The module of sheet substitutes, and the module of band radiating fin can play thermolysis, but area is relatively big, is easily subject to unit knot
Restriction on structure.
Fig. 6 is the structural representation of the anti-condensation system of power component according to embodiments of the present invention, as shown in Figure 6, anti-
The mainboard of condensation system, with temperature sensor and relative humidity sensor, is used for experiencing and feed back band heating power components and parts institute
The environment at place.
Understand from above description:
1) present invention is by detecting the condensation point of power component local environment, controls coolant amount of cooling water, controls coolant cold
But temperature is in the range of suitably, it is achieved power component surface does not occur condensation, it is ensured that the power component of mainboard can burn
Ruin and cause cancel closedown, it is ensured that the reliability of unit.
2) compare the low of power component due to the refrigerant temperature in pipeline so that the refrigerant temperature in pipeline and power
Component surface forms the temperature difference, so by the coolant of flowing in pipeline, the heat that power component produces can be taken away, thus
Being not result in heat accumulation, it is overheated to cause, and burns power component, it is ensured that the reliability service of unit.
3) present invention is controlled coolant amount of cooling water by the stop valve of changeable flow, will not be as other schemes are by limit frequency
Dispel the heat with modes such as frequency reducing or start-stop heat radiations so that it is remain at one and adapt with power component local environment
Temperature, prevent power component from colding and heat succeed each other, cause that ess-strain is excessive and the problem such as premature aging.
4) present invention need not carry out anti-condensation by limit frequency and frequency reducing, and outer machine can be carried out along with the ability need of interior machine
Regulation, it is not necessary to by frequency reducing and limit frequency, bring to user and stablize comfortable environment.
To sum up, present invention mainly solves following technical problem: prevent transducer air conditioning power component surface from being formed solidifying
Dew, it is ensured that the reliability of unit；It is embodied as power component heat radiation；The ess-strain preventing power component is excessive, cold and hot friendship
For causing the problems such as mainboard premature aging；The ability need of unit can be met, it is not necessary to prevented by forms such as frequency reducing and limit frequencies
Condensation.
Certainly, it is above the preferred embodiment of the present invention.It should be pointed out that, for those skilled in the art
For, on the premise of without departing from its general principles, it is also possible to make some improvements and modifications, these improvements and modifications are also
It is considered as protection scope of the present invention.
