Description of the drawings
The attached drawing for forming the part of the application is used for providing a further understanding of the present invention, schematic reality of the invention
Example and its explanation are applied for explaining the present invention, is not constituted improper limitations of the present invention.In the accompanying drawings：
Fig. 1 is the structure diagram of air-conditioner set according to the present invention.
Specific embodiment
The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in Figure 1, air-conditioner set according to the present invention, including：Frequency converter 10；Independent cooling system 20, for becoming
The cooling heat dissipation of frequency device 10；Machine set control device 30 detects the working condition of frequency converter 10；And according to the work shape of frequency converter 10
State, control independent cooling system 20 are opened or stopped.It is i.e. of the invention by setting independent cooling system 20, and according to frequency converter
10 working condition, control independent cooling system 20 are opened or stopped.Namely frequency converter 10 works, then independent cooling system 20
Unlatching, frequency converter 10 do not work, then independent cooling system 20 stops, and the cooling for solving frequency converter 10 in the prior art is necessary
The problem of relying on cooling cycle system, can not be to frequency converter without running in cooling cycle system so as to solve air-conditioner set
The problem of 10 cooling.
Preferably, machine set control device 30 further includes the first temperature controller, and the first temperature controller detects environment temperature,
And the design temperature of independent cooling system 20 is controlled according to environment temperature.By detecting environment temperature, so as to control independent cooling
The design temperature of system, i.e. independent cooling system can also play adjusting air conditioning while heat dissipation is cooled down to frequency converter 10
The effect of the temperature of environment where group.For example, correspondence generally has special computer room for larger-size business air conditioner unit,
In the basement or roof of building, independent cooling system can also play the role of adjusting building environment temperature.It is namely independent
Cooling system is equivalent to a set of minitype air conditioner, plays an important role of adjusting ambient temperature, environment temperature is made to be maintained on design temperature
Lower a certain range, as long as machine set control device 30 changes this design temperature and achievees the purpose that control environment temperature.
Preferably, machine set control device 30 further includes second temperature controller, second temperature controller detection frequency converter 10
Temperature, and according to the temperature of frequency converter 10 control independent cooling system 20 refrigerant flow.Usually, independent cooling system
Flow control valve is provided on the cooling line of 20 pairs of frequency converter cooling heat dissipations, by detecting the temperature of frequency converter 10, so as to control
Flow control valve processed makes the temperature of frequency converter 10 be maintained in suitable scope.
Air-conditioner set further includes cycle refrigeration system 40（It is equivalent to the refrigeration system of air-conditioner set of the prior art）, follow
Ring refrigeration system 40 and 20 independent control of independent cooling system, the two refrigerant also mutually completely cut off.Namely independent cooling system 20
It is turned on or off being turned on or off independent control with cycle refrigeration system 40, prevents the two from interfering, also make frequency converter
It is related whether 10 cooling heat dissipation is only worked completely by frequency converter, and is disturbed from other factors.Cycle refrigeration system 40 includes
