One, the control principle of frequency conversion air conditioning and main characteristic
Frequency conversion air conditioning implement with common air conditioning implement or say to decide rotate speed air conditioning implement main distinction is former increased transducer. Frequency conversion air conditioning implement the concerned information that microcomputer gathers indoor environment at any time and in-house set value are compared, via operation processing output controls signal. Air conditioning of communication frequency conversion implement working principle is a labour frequency alternating current changeover is direct current source, send power module it (high-power transistor switch combines) ; At the same time module gets the control signal control that microcomputer delivers, output frequency is handed in adjustably change power source (synthesize) of wave of undee and approximate sine, the change that makes the rotate speed of compressor electric machinery follows power source frequency makes corresponding change, control the platoon amount of compressor thereby, move section refrigerating capacity or heating capacity. Air conditioning of dc frequency conversion implement it is changeover of labour frequency alternating current likewise direct current source, send to power module, module gets the control signal control that microcomputer delivers likewise, what what differ is the direct current source with module controlled output (without inversion link) the dc plane that sends to compressor, control the platoon amount of compressor, because this sheds frequency conversion air conditioning continuously implement more province report, noise is less.

Its are main the characteristic is:
1, the rotate speed stepless that transducer can make compress Electromechanical motive is successive and adjustable, its rotate speed becomes scale change according to bear of indoor air conditioning, when indoor need quickness drops in temperature (or quickness warms up) , when air conditioning bear is increased, compressor rotate speed is accelerated, refrigerating capacity (or heating capacity) increase in proportion, when reaching set temperature, immediately is in low speed movement to maintain room temperature basic and changeless.

2, frequency conversion air conditioning implement reduce expenditure is to apply an electron to expand a powerful person controls flow, its microprocessor outdoor is expanding according to setting the open that the information that the temperature sensor of tracheal place in imports and exports of a powerful person, compressor gathers will come to control valve is spent, change the discharge of refrigeration agent at any time. The rotate speed of compressor and expand the open of a powerful person spends photograph correspondence, make the ability of evaporator gets the play of utmost. In the meantime, because used an electron to expand,a powerful person regards reduce expenditure as component, when changing frost, keep machine, the quantity of heat that uses compressor exhaust first to indoor heat addition, the rest of quantity of heat send outdoor, heat exchanger wing piece the frost that go up melts.
