Description
Technical field
The utility model relates to the air conditioner controlling technology field, particularly relates to the control circuit of the cold one drag two air-conditioner outdoor unit of a kind of list.
Background technology
Existing one drags the control mode of many air-conditionings mainly to be: indoor controller and outdoor controller that exploitation is special-purpose, and between the two according to same communication protocol.Indoor controller is communicated by letter mutually with outdoor controller, the indoor main controls such as operational mode, temperature of being responsible for setting, adopt the mainly pattern conflict adjusting of responsible two machines of off-premises station of double-compressor, the off-premises station of employing single compressor mainly is responsible for the refrigerant flow control of each indoor set etc.So must under the situation that indoor and outdoor is mated simultaneously, just can install and use.Present Dan Lengyi drags many air-conditionings to have following shortcoming:
(1), in the control often with the air conditioner compatibility, so the control technology difficulty is big, poor reliability; The control object is complicated, and the indoor and outdoor controller all must prepare specially;
(2), versatility is poor, the kind that manufacturer production goes out is few, at user option kind is few.Many troubles are provided for manufacturer production, installation and user's selection;
(3), indoor and outdoor is electrically connected complexity, installation trouble, cost height.
China's ZL01258284.0 patent " many air-conditioner controllers are dragged in frequency conversion one " disclosed a kind of frequency conversion one drags many air-conditioner controllers, at corresponding unilateral system thermoelectrical magnetic valve, individual event refrigeration magnetic valve and the unloading magnetic valve of being provided with of outdoor controller, sort controller can be applicable to many moneys air-conditioning system, can be according to the suitable power of different ability needs output of indoor set, thus reach control flexibly, power saving, comfortable effect.But still there is above-mentioned defective in the control system that it provided.
The utility model content
Technical problem to be solved in the utility model provides the cold one drag two air-conditioner outdoor unit of the list control circuit of a kind of generalization, practicability.
The utility model is achieved through the following technical solutions:
The cold one drag two of a kind of list is controlled circuit outside the air conditioning chamber, comprises peripheral control circuit of outdoor controller, controller and the double-compressor that is connected thereof, blower fan, and being provided with one in the control signal circuit that is connected of indoor set and off-premises station has many-contact relay.Relay is one four a contact relay, the control signal wire polyphone of 1,2 and No. 2 compressors of normally-closed contact, the control signal wire polyphone of 3,4 and No. 1 compressors of normally opened contact, 5,6 ports and outdoor fan polyphone, 7, between 8 ports be relay control coil, with the control signal wire polyphone of No. 1 indoor set output.
Described outdoor control circuit only connects a typhoon machine, every independent circuits system of indoor set, a public condenser.
The utility model compared with prior art, the advantage that has is as follows:
1, highly versatile: can with the supporting use of the cold indoor set of existing arbitrary list.Kind is increased greatly, bring convenience for the production of air-conditioner, user's selection.
2, the indoor and outdoor line is few, and has only used a relay to coordinate control, and line is simple, brings convenience to installation and maintenance, has also lowered material cost greatly.Do not need to increase in addition controller, reduced development cost yet.
Description of drawings
Specific embodiments
The utility model is described in further detail below by embodiment:
With reference to shown in Figure 1, for the ease of general, the existing frequency indoor set of producing of deciding does not change fully, and no longer increase under the situation of new controller, the outer one drag two air-conditioning practical control mode in the exploitation single cold house of one cover, can with single cold indoor set coupling use arbitrarily, native system adopts two compressor CM1, CM2, the outer blower fan FM system of single chamber, every indoor set uses an independent circuits system, a shared condenser.And indoor set is used existing product fully, arbitrarily coupling.
Indoor set outputs to one the 3 core connecting line that has of off-premises station, is respectively: signal compressor line, public N line and power ground, compressor and outdoor fan move simultaneously.Two indoor sets are exactly two connecting lines.With these two holding wires that the forceful electric power line is sent as indoor set, off-premises station mainly is the action that the various operating state signals of indoor set that this two signal line is transmitted coordinate to control outdoor fan, present embodiment is established a many-contact relay K on this two signal line, be used for coordinating the run action of control room external compression machine, blower fan.The holding wire of No. 1 compressor CM1 is connected on the terminal C1, common wire is connected to terminal N1, the holding wire of No. 2 compressor CM2 is connected on the terminal C2, common wire is connected on the terminal N2, relay is one four a contact relay, the control signal wire polyphone of 1,2 and No. 2 compressors of normally-closed contact, the control signal wire polyphone of 3,4 and No. 1 compressor CM1 of normally opened contact, 5,6 ports and outdoor fan FM polyphone, be relay control coil between the contact 7,8, with the control signal wire polyphone of the output of No. 1 indoor set A.
| Sequence number | The indoor set | Compressor | 1 | Compressor 2 | Outer blower fan | |
| No. 1 indoor set | No. 2 | |||||
| 1 | Standby/air-supply | Standby/air-supply | Close | Close | Close | |
| 2 | Standby/air-supply | Refrigeration/dehumidification | Close | Open | Open | |
| 3 | Refrigeration/dehumidification | Standby/air-supply | Open | Close | Open | |
| 4 | Refrigeration/dehumidification | Refrigeration/dehumidification | Open | Open | Open | |
When system was in the table listed first group of situation, indoor not have signal to be input to outdoor, therefore, compressor, outer blower fan is not opened; When system was in second group of situation of table 1, No. 1 indoor set A did not have signal to transmit, and No. 2 indoor set B has signal to transmit, so No. 1 compressor CM1 does not open, No. 2 compressor CM2 opens, and this moment, relay was in normally closed position, so outer blower fan FM opens; When system was in the 3rd group of situation of table 1, No. 1 indoor set A had signal to transmit, and No. 2 indoor set B does not have, and No. 1 compressor was opened CM1 and opened this moment, and No. 2 compressor CM2 does not open, and the relay K contact is in 3,4 positions, so outer blower fan FM opens; No. 1, No. 2 indoor set A, B all have signal to transmit when system is in the 4th group of situation of table 1, and this moment, 1, No. 2 compressor CM1, CM2 opened, and the relay K contact is positioned at 3,4 positions, and outer blower fan is opened.
Adopt the utility model that the off-premises station control model is provided, can be complementary with the cold indoor set of any list, reach " self-service set meal formula " collocation and use, improve the selection space of versatility and type, bring convenience for the production of air-conditioner, user's selection and installation and maintenance.
