The heating wire 5 is attached to the second chamber 4, and the second heating wire is mounted; the air-cooling device implements the cooling system, the single cycle refrigeration system includes a circulating airway 7, a compressor 8, and an evaporator 9, setting The rear side outside the inner bile 2; an evapogenating fan 10 is provided on the rear side of the inner bile 2, and a chemical sensor for detecting the temperature of the frost temperature is mounted on the evapogenation fan 10 (not shown); in the first The chamber 3 is opened on the opening, the first door 11 is connected to the circulating airway 7; the second wind gate 12 is opened on the second chamber 4, the second door 12 and the circulating air passage 7 .
[0023] Such as figure 1 In the architecture of the present invention, the present invention proposes its control method to achieve a double temperature constant temperature control, specifically, such as a single cycle refrigeration system. figure 2 As shown, including the following steps:
[0024] Step S21: Start the compressor and evaporative fan, open the first damper and the second damper.
[0025] Taking the air-cooled device to start the refrigeration as an example, after the air-cooling device is turned on, the first-line refrigeration system is first selected, and the first wind door 11 and the second wind doors 12 are opened, respectively, respectively, respectively, respectively, and the second chamber. 4 Implement the cooling.
[0026] Step S22: Decades whether the cooling temperature of the two rooms meets the refrigeration requirements.
[0027] During the cooling period of the two rooms, it is judged whether or not the cooling temperature of the two rooms reaches the respective refrigeration requirements. After a period of refrigeration, there are two cases of the cooling of the two rooms: 1, all achieve the refrigeration requirements, all Need to enter constant temperature adjustment; 2, a room has reached its refrigeration requirements to enter constant temperature adjustment, and the other room does not reach its refrigeration requirements, it is necessary to continue refrigeration.
[0028] Based on the above two cases, the control method proposed by the present invention performs different steps, respectively, and when the case 1 performs step S23: Control the compressor to stop, open the first damper and the second damper, and control the evaporation fan to continue operation, And start the first heating wire and the second heating wire.
[0029] After the two rooms have reached its refrigeration, the first heating wire 5 of the first chamber 3 is initiated, and the second heating wire 6 of the second chamber 4 is activated, and the second chamber 4 is activated. Implement constant temperature control; The surface temperature of the device is subjected to compensation heating through the constant temperature control of the operation of the evaporative fan 10, specifically, when the compressor 8 is stopped entering the constant temperature control, the operation of the evaporative fan 10 is maintained, and the first wind door 11 and the second wind doors are maintained. 12 Open the state, and start the compensation heating wire 13, when the constant temperature adjustment is performed by its own heating wire, the heat of the heating wire 13 compensates for the heat of the heating wire 13 through the evaporation fan 10, and enter the first The chamber 3, the second door 12 enters the second chamber 4, and compensation is performed on the temperature of the two chambers.
[0030] When the case 2 occurs first, or during the constant temperature adjustment process in step S23, a chamber needs to be heated, and the other chamber needs to be refrigerated, the first chamber 3 needs to be refrigerated, the second chamber 4 needs to heat Take an example, execute
[0031] Step S24: Control the compressor and the evaporation fan operation, open the first damper and turn off the second wind door, and start the second heating wire.
[0032]Start the compressor 8, the evaporative fan 10 continues to operate, open the first door 11 and turn off the second wind door 12, keep the second heating wire 6 start operation, the first wind gate 11 enters the first chamber 3 through the first wind door 11 of the single cycle refrigeration system The first chamber 3 is refrigerated, and since the second door 12 is closed, the second chamber 2 does not enter the cold air, and the operation heating of the second heating wire 6 is heated, during this, when the first chamber 3 reaches again When it is set, when refrigeration is refrigerated,
[0033] Step S25: Control the compressor shutdown and delay the first damper when the first set temperature is reached.
[0034] After the first chamber 3 reaches its refrigeration requirements, the compressor 8 is turned on, and the chemical temperature detected by the chemical sensor is obtained. When the chemical temperature reaches the first set temperature T1, the first door 11 is closed.
[0035] After the compressor 8 is stopped, the compensation heating wire 13 is started immediately, and the auxiliary evaporator 9 is chemically, in order to improve the surface temperature of the evaporator 9, prepare for the constant temperature regulation of the subsequent intermediate chamber.
[0036] Step S26: Open the second door when the first damper is closed after the first damper is closed, and the second wind door is turned on when the second set temperature is reached.
[0037] After the first wind door 11 is closed, the second chamber 4 continues to heat, obtain the chemical temperature detected by the chemical sensor, when the chemical temperature reaches the second set temperature T2, turn on the second wind door 12, due to the shutdown of the compressor 8 Within the time period on which the second door 12 is turned on, the compensation of the heating wire 13 has been turned on, and the evaporator 9 has a higher surface frost temperature. When the second door 12 is turned on, heating can be compensated for the heating of the second chamber 4. Accelerate the constant temperature adjustment of the second room 4.
[0038] Step S27: Turns the second heating wire when the heating temperature is satisfied in the second chamber.
[0039] When the control of the evaporative fan 10, when the chemical temperature reaches the first setting temperature T1, the first damper 11 is turned off in step S25, the evaporative fan 10 is turned on, at which time the compensation heating wire 13 is opened, the evaporator 9 Implement the auxiliary chemical temperature to increase the chemical temperature as soon as possible; when the chemical temperature reaches the second set temperature T2, the second damper is turned on, and the evaporation fan 10 is started again, and the evaporation fan 10 is used. Faster, the heating of the second chamber 4 is compensated, and the constant temperature adjustment of the second chamber 4 is further accelerated until the second chamber satisfies the heating temperature after closing.
[0040] Thereafter, if two rooms are refined or heated during the constant temperature control, the two rooms given by the above steps, and the two rooms are simultaneously refrigerated while heating, and a refrigeration is separate. The constant temperature adjustment is performed, compared to the existing way to achieve a constant temperature controlled double-evaporator + double vapor + two heating wire + solenoid valves, since the solution is achieved based on single cycle refrigeration system, structural design and process is more simplified. The constant temperature control of the air-cooling equipment of single wind-cooling system is achieved with simplified structural and process design, which is more suitable for industrial application.
[0041] After step S26 above, when the compressor 8 is started again, the second damper 12 is immediately turned off, i.e., as long as the compressor 8 is running, it is necessary to immediately close the damper of the chamber currently heating, to avoid the impact of cold wind on heating.
[0042] After the first heating wire 5 and the second heating wire 6 are started, each of the power-up rate required by the heating gear is operated, and after the power supply wire 13 is turned on, it operates according to 100% energization rate.
