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.
