Description
Technical field
The present invention relates to a kind of air-conditioning control part, particularly relate to a kind of can be by the common control unit of air-conditioning compressor that uses of the driving power of the driving power of compressor and outdoor fan.
Background technology
Usually, air-conditioning is meant the cold-room endless form work with evaporation → compression → cohesion → a series of sequential loop such as expansion in summer, and in the winter time by cross valve is adjusted, make its greenhouse endless form work, thereby indoor temperature is remained on the cold/house warming system of the required level of user with the heat pump (Heat pump) opposite with above-mentioned cold-room circulation.Air-conditioning also has the outer contaminated air of suction chamber and is converted to after the peace and quiet air by it is filtered when having common cold/greenhouse function, is blown into the indoor air purifying function again; The suction malaria also is converted into after the dry air, is blown into indoor dehumidification function etc. again.
Fig. 1 is the structure chart that common air-conditioning inside is carried out schematic representations.
In Fig. 1, symbol " 16 " and " 35 " and " 37 " are represented indoor fan, outdoor suction inlet and outdoor fan respectively.
Below, the cyclic process with cold/refrigerant during the greenhouse mode operation describes to air-conditioning equipment.
At first the situation during with the cold-room mode operation describes to air-conditioning equipment.Refrigerant under the high-temperature high-pressure state that spues from compressor 34 flow in the outdoor heat exchanger 36 under the effect of cross valve 32, the refrigerant that flows into the high-temperature high-pressure state in the outdoor heat exchanger 36 then is converted to the refrigerant of low-temp low-pressure state by carrying out the refrigerant that heat exchange is condensed into liquid condition with the outdoor air that is drawn in the off-premises station 30 by bloating plant 38.The refrigerant of above-mentioned low-temp low-pressure state then will flow in the above-mentioned indoor heat exchanger 12, and by carrying out the temperature that heat exchange reduces room air with the room air that is drawn in the indoor set 10, flow into again in the compressor 34 at last.Therefore under the state with the cold-room mode operation, refrigerant is mobile by the reiteration of press compressor 34 → outdoor heat exchanger 36 → bloating plant 38 → indoor heat exchanger 12 → compressor 34, and the temperature of conditioned space 1 is reduced to set temperature.
Then the situation during with the greenhouse mode operation describes to air-conditioning equipment.Refrigerant under the high-temperature high-pressure state that spues from compressor 34 flow under the effect of cross valve 32 in the indoor heat exchanger 12, and the refrigerant that flows into the high-temperature high-pressure state in the indoor heat exchanger 12 is by carrying out the temperature that heat exchange promotes room air with the room air that is drawn in the indoor set 10.Flow through refrigerant in the indoor heat exchanger 12 is converted to the low-temp low-pressure state in the process by bloating plant 38 refrigerant, then after flowing through outdoor heat exchanger 36, finally flow into again in the compressor 34.Therefore under the state with the greenhouse mode operation, refrigerant flows by the reiteration according to compressor 34 → indoor heat exchanger 12 → bloating plant 38 → outdoor heat exchanger 36 → compressor 34, with the temperature increase of conditioned space 1 to set temperature.
In above-mentioned structure shown in Figure 1, for compressor and outdoor fan are driven, need to use separately independently power supply under the existing state of the art.Below, in conjunction with the accompanying drawings its structure is described in detail.
Seeing also shown in Figure 2ly, is that the control part that is used for Driven Compressor and outdoor fan is carried out illustrated figure, wherein the control part of (a) expression compressor, (b) control part of expression outdoor fan.
The control part that is used for Driven Compressor (Fig. 1 34) comprises that the alternating voltage (AC voltage) that is used for being connected to AC power portion is converted to the 1st converter section 104 of direct voltage (dc voltage); Direct current (DC) voltage after will changing by above-mentioned the 1st converter section 104 is converted to the 1st frequency conversion portion 102 of the required alternating voltage (AC voltage) of Driven Compressor drive division 100 once more; The final alternating voltage of exporting by above-mentioned the 1st frequency conversion portion 102 that utilizes carries out compressor driven drive division 100 to compressor (34 among Fig. 1).And be used for the control part of drive chamber's external fan (Fig. 1 37), comprise that the alternating voltage (AC voltage) that is used for being connected to AC power portion is converted to the 2nd converter section 114 of direct voltage (dc voltage); Direct current (DC) voltage after will changing by above-mentioned the 2nd converter section 114 is converted to the 2nd frequency conversion portion 112 of the required alternating voltage (AC voltage) of drive chamber's external fan drive division 110 once more; The outdoor fan drive division 110 that the alternating voltage that final utilization is exported by above-mentioned the 2nd frequency conversion portion 112 drives outdoor fan (37 among Fig. 1).
As shown in the figure, need to install separately the control part that is used for Driven Compressor (Fig. 1 34) and outdoor fan (37 among Fig. 1) in the existing air-conditioning equipment.That is, be separately installed with by three-phase 380V is carried out full-wave rectification, DC 540V be used for the control part of the driving power of compressor (Fig. 1 34); And by three-phase 380V is carried out halfwave rectifier with the N phase reference, DC 310V is used for the control part of the driving power of outdoor fan (Fig. 1 37).
But except the final voltage swing that uses of compressor (34 among Fig. 1) and outdoor fan (37 among Fig. 1) was different, the drive principle of compressor and outdoor fan was basic identical.In the prior art promptly, used independently control part respectively just to obtaining different driving voltages.In said structure,, can cause the lifting of production cost because need to be equipped with control part that is used for Driven Compressor and the control part that is used for drive chamber's external fan separately.
