Description
Technical field
The present invention relates to field of air conditioning, it is especially a kind of to determine frequency one drag two air-conditioner set.
Background technology
Common fixed frequency air conditioner is an outer machine and an interior machine, is provided with a compressor and a blower fan in outer machine.This
Sample, if it is desired to driving two interior machines, generally requires two outer machines.However, the competition day to price for the air conditioner industry domestic at present
Benefit is white-hot, to the control of cost also even to the degree haggled over every penny.So, for controlling cost, nature is it has been proposed that set
Think, drag two interior machines with an outer machine, in this outer machine, be provided with two invariable frequency compressors, a heat exchanger and a blower fan,
Two compressors are individually powered by machine in two respectively, and two compressors share this heat exchanger and blower fan, to realize reduces cost, reduce
The purpose that outer body amasss.
However, above-mentioned imagination has a critical technical barrier, how to realize outer machine two compressor circuit
Control and interlock because traditional control mode list open any interior machine and to corresponding compressor power when, this compressor and
Blower fan can normally run, but if open two interior machines simultaneously, when two compressors are powered, zero live wire of blower fan just occurs
Short circuit and fall machine.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of interlocking enabling two compressors it is ensured that either single
Drive an interior machine and still drive two interior machines simultaneously, compressor and blower fan all can normal work, avoid short circuit, reduces cost determine frequency
One drag two air-conditioner set.
The technical solution of the present invention be to provide a kind of there is following structure determine frequency one drag two air-conditioner set, it wraps
Include machine in machine and second in first,
This unit also includes an outer machine, is provided with the first invariable frequency compressor, the second invariable frequency compressor, heat exchange in outer cage body
Device and the blower fan to this heat exchanger heat exchange；Two invariable frequency compressors share this heat exchanger, are equipped with the first heat exchange disk in heat exchanger
Pipe and the second heat exchange coil；In first invariable frequency compressor, the first heat exchange coil and first, mechanism becomes the first refrigerant circulation circuit, the
In two invariable frequency compressors, the second heat exchange coil and second, mechanism becomes the second refrigerant circulation circuit；Two interior machines are respectively to each right
The invariable frequency compressor answered is powered；
The control circuit of this outer machine includes the first relay and the second relay, and the first relay includes a First Line
Circle, first normally-closed contact and two the first normally opened contacts, the second relay include second coil, one second normally closed
Contact and two the second normally opened contacts；
The zero line of the first invariable frequency compressor is connected with the second normally-closed contact entrance side, the outlet side of the second normally-closed contact with
The arrival end of first coil connects, and the port of export of first coil is connected with the zero line side of the first invariable frequency compressor；Second is normally closed tactile
The outlet side of point is also connected with the incoming end of blower fan through first normally opened contact, and the exit of blower fan is first normally opened through another
Contact is connected with the zero line side of the first invariable frequency compressor；
The zero line of the second invariable frequency compressor is connected with the first normally-closed contact entrance side, the outlet side of the first normally-closed contact with
Second coil arrival end connects, and the second coil port of export is connected with the zero line side of the second invariable frequency compressor；First normally-closed contact
Outlet side is connected with the incoming end of blower fan through second normally opened contact, the exit of blower fan through another second normally opened contact with
The zero line side of the second invariable frequency compressor connects.
Divide the course of work of three kinds of this control circuits of status analysis.Certainly, first explain the operation principle of relay, work as relay
Device coil obtain electric after, the normally opened contact close access of relay and normally-closed contact disconnecting circuit.
Situation one, the first indoor set is individually started shooting, and zero zero line of the first invariable frequency compressor is individually powered, so,
First coil obtains electric and the second coil is no electric, and the first normally-closed contact and two the second normally opened contacts all disconnect, the second normally-closed contact
All close with two the first normally opened contacts, and electric current from the zero line of the first invariable frequency compressor through the second normally-closed contact, one
One normally opened contact reaches the incoming end of blower fan, then returns to the first fixed frequency pressure by the exit of blower fan through another first normally opened contact
Contracting machine zero line side, that is, the first invariable frequency compressor and blower fan all electric normal work.
Situation two, the second indoor set is individually started shooting, and zero zero line of the second invariable frequency compressor is individually powered, so,
Second coil obtains electric and first coil is no electric, and the first normally-closed contact and two the second normally opened contacts all close, the second normally-closed contact
All disconnect with two the first normally opened contacts, and electric current from the zero line of the second invariable frequency compressor through the first normally-closed contact, one
Two normally opened contacts reach the incoming end of blower fan, then return to the second fixed frequency pressure from the exit of blower fan through another second normally opened contact
The zero line side of contracting machine, that is, the second invariable frequency compressor and blower fan all electric normal work.
Situation three, two interior machines are all opened, zero live wire of two invariable frequency compressors all electric, if the first invariable frequency compressor
Zero live wire first electric, then electric current first reaches first coil through the second normally-closed contact, leads to the first normally-closed contact to disconnect it is ensured that the
Two coil will not obtain electric, therefore under this state, two compressors all normal electric work, and the first normally-closed contact and two second normal
Open contact all to disconnect, the second normally-closed contact and two the first normally opened contacts all close, and electric current is from the fire of the first invariable frequency compressor
Line end reaches the incoming end of blower fan through the second normally-closed contact, first normally opened contact, then by blower fan exit through another
First normally opened contact returns to the first invariable frequency compressor zero line side.
Certainly, if state three be the second invariable frequency compressor zero live wire first electric, be equally that two compressors are normal
Obtain electric work, and electric current reaches blower fan from the zero line of the second compressor through the first normally-closed contact and second normally opened contact
Incoming end, then return to the second invariable frequency compressor zero line side from the exit of blower fan through another second normally opened contact.
To sum up, this control circuit achieves the interlocking of two compressors it is ensured that either singly driving an interior machine still simultaneously
Drive two interior machines, compressor and blower fan all can normal work, avoid short circuit, solve technical barrier for many years in puzzlement industry,
Effectively prevent the situation that blower fan short circuit is burnt.And, the outer machine of this unit is powered without other, fully achieves the power supply of interior machine
And control, simplify installation difficulty, and outer machine no longer sets control panel, reduces cost, moreover foregoing circuit control process is stable
Reliable.Moreover, above-mentioned two compressor shares a set of heat exchanger and blower fan, further reduces the cost of unit, and reduces
The overall volume of outer machine.
