The technical scheme that the utility model provides is: construct a kind of double compressor system room air conditioner circuit control system, comprise control circuit board, indoor set drive circuit board that is electrically connected with described control circuit board and off-premises station drive circuit board, described outdoor drive plate are provided with two group relaies that can connect two compressors under the control of described control circuit board respectively, three group relaies that can connect three magnetic valves respectively.
In above-mentioned double compressor system room air conditioner circuit control system, described control circuit board is made up of single-chip microcomputer, SCM peripheral circuit.
In above-mentioned double compressor system room air conditioner circuit control system, on described indoor drive plate, be provided with the relay corresponding and exchange conversion DC power supply circuit, overcurrent-overvoltage protecting circuit with wind direction motor, indoor fan motor, electric heater.
In above-mentioned double compressor system room air conditioner circuit control system, on described outdoor drive plate, also be provided with relay corresponding and overcurrent-overvoltage protecting circuit and form with outdoor fan motor, cross valve.
The circuit control system of the double compressor system room air conditioner that enforcement the utility model provides, by the relay that can control the relay of two compressors and control three magnetic valves respectively is set respectively, can satisfy the control requirement of double compressor system room air conditioner fully on outdoor drive plate.Can determine the platform number that compressor is opened according to the variation of room load, make ability output that certain self-regulation be arranged, avoid waste, improve the service efficiency of the energy; Can improve the efficiency in season greatly, reduce manufacturing cost, also reduce user's use cost, satisfy user's request.
Description of drawings
Fig. 1 is a double compressor system room air conditioner circuit control system connection diagram;
Fig. 2 is the electrical schematic diagram of control circuit board in the control system shown in Figure 1.
The specific embodiment
With reference to Fig. 1, whole system is graded by funtion part, main control part, indicating section, operation part, transducing part, power supply unit and is formed, indoor set, off-premises station adopt independent power supply power supply, master board 1 is electrically connected with indoor drive plate 2, outdoor drive plate 3 by signal link, is provided with two group relaies that can control compressor A and compressor B respectively and three group relaies that can control three magnetic valve C, D, E respectively on outdoor drive circuit board 3.
In above-mentioned double compressor system room air conditioner circuit control system, control circuit board 1 can adopt existing single-chip microcomputer and SCM peripheral circuit to constitute, and writes the program of control double-compressor operation in single-chip microcomputer.The relay that is provided with wind direction motor, indoor fan motor, electric heater correspondence on indoor drive plate 2 is changed DC power supply circuit, overcurrent-overvoltage protecting circuit with exchanging.
On outdoor drive plate, be provided with the relay and the overcurrent-overvoltage protecting circuit of compressor A, compressor B, outdoor fan motor, cross valve, magnetic valve correspondence.
Adopt the mode of independent power supply power supply to power indoor set and off-premises station, can avoid the power supply line between indoor set and the off-premises station too much, reduce cost.
The control principle of double compressor system room air conditioner circuit control system is as follows: with reference to Fig. 1, two compressors are A, B, compressor A can be set at long-time running.When starting air-conditioning, A compressor A is moving earlier, and compressor B postpones T1 and starts after second.Be connected the magnetic valve in the bypass line, ratio piston compressor B moves T2 second in advance when compressor B starts, and closes in second at T3;
The control of magnetic valve requires: when refrigeration mode: 1. compressor A, B moves simultaneously, magnetic valve C, D no power.2. when having only compressor A operation, magnetic valve C energising, magnetic valve D no power; When heating mode: 1. compressor A, B moves simultaneously, magnetic valve C, D no power.2. has only press A operation, magnetic valve C no power, magnetic valve E energising.Oil return control function: 1. under refrigeration, dehumidification mode, have only the operation of compression A machine, and compressor A reaches T4 hour running time, start compressor B, two-shipper moves T5 minute jointly, closes compressor B.2. under refrigeration, dehumidification mode, in compressor A machine running, compression B machine moves the timing zero clearing.3. restart after compression A machine is shut down or user when just having started shooting, two-shipper moves T6 minute jointly.
