Step 1, refrigerator room 302, alternating temperature compartment 304 and the compartment door of freezing compartment 306 are closed；

Step 2, realize that freezing blower 312 is fixed as a certain revolving speed by DC power supply 324；

Step 3, realize that throttle condition is refrigerator room air door 308, alternating temperature compartment air door by the Macintosh of master control borad 322 310 are out；

Step 4, by the anode of corresponding first hose, the 316 lateral ends cut-in pressure table 314 of refrigerator room 302, simultaneously Corresponding second hose 318 of alternating temperature compartment 304, corresponding 320 lateral ends of third hose of freezing compartment 306 are sealed with adhesive tape Firmly, prevent influence result accurate；

Step 5,1 minute is waited, waits the rotation of air door machinery to terminate, and pressure balance is established in refrigerator；

Step 6, read pressure gauge 314 reading and it is positive and negative.

For freezing the voltage selection of blower 312: according to the maximum probability environment in the faced market of concrete model, finding program The freezing blower voltage of the middle correspondence maximum probability environment is surveyed as that must survey voltage according to (1), (2), (3), (4) four kinds of states It is complete.

It tests after must surveying voltage, pressure in the case to each compartment is needed to judge with the presence or absence of negative pressure and condensation hidden danger Analysis.The reason of generating negative pressure can be different because of the switch state of different air doors, need the switch shape in conjunction with air door State analyzes negative pressure reason, makes a concrete analysis of as follows:

1. (1) state of being directed to, refrigerator room air door 308, alternating temperature compartment air door 310 are out, Fig. 5 is shown under the state The negative pressure condition of each compartment, refrigerator room 302 is positive pressure, alternating temperature compartment 304 is positive pressure, freezing compartment 306 is positive pressure.

Under the state, refrigerator room 302, alternating temperature compartment 304 do not allow negative pressure occur, because of refrigerator room air door 308, change Warm compartment air door 310 has air-supply when opening, and there is also negative pressure for refrigerator room 302, alternating temperature compartment 304 at this time, then refrigerator room Only return air suction is not blown after air door 308, alternating temperature compartment air door 310 are closed, and can predict that negative pressure is more serious.

Freezing compartment 306 is possible to negative pressure occur, the monosystem that especially stringcourse is relatively low, refrigeration is more much larger than freezing volume System refrigerator.The reason of negative pressure occur is that the air-supply that refrigerator room 302, alternating temperature compartment 304 distribute is larger, leads to freezing compartment 306 Air output be less than freezing return air.There are two improved directions, increases freezing air-supply or reduces freezing return air, and increases freezing Air-supply meeting refrigerating matching imbalance, is unable to satisfy demand of the refrigeration load to air quantity, in order to guarantee refrigerator room 302, alternating temperature The refrigerating capacity of compartment 304 cannot increase freezing air-supply.So can only reduce to freezing return air.

2. (2) state of being directed to, refrigerator room air door 308, alternating temperature compartment air door 310 are to close, and Fig. 6 is shown under the state The negative pressure condition of each compartment, refrigerator room 302 is negative pressure, alternating temperature compartment 304 is negative pressure, freezing compartment 306 is positive pressure.

Under the state, freezing compartment 306 does not allow negative pressure occur, because dividing without refrigerator room 302, alternating temperature compartment 304 In the case where air quantity, still there is negative pressure in freezing compartment 306, then freeze air-supply it is too small, be not able to satisfy freezing air-supply require.It can be with When predicting that air door is opened, 306 negative pressure of freezing compartment is more serious.

Refrigerator room 302, alternating temperature compartment 304 can be predicted to will appear negative pressure certainly, because of refrigerator room air door 308, change Warm compartment air door 310 is closed, and only return air aspirates, and is not blown.

The main reason for such case is current refrigerator room 302, the generation gallbladder side surrounding generation condensation of alternating temperature compartment 304, If negative pressure condition does not improve, only improve case courage sealing and increase anti-condensation pipe if cannot change negative pressure it is serious when Hot wet air heating Trend into cold storage temperature variable case, so that refrigeration gallbladder side condensation problem cannot be solved fundamentally.

Reduce the schematic diagram of refrigeration negative pressure, L1 when Fig. 9 shows refrigerator room air door 308, alternating temperature compartment air door 310 is closed The power curve that pressure curve, L2 for refrigerator room 302 are the pressure curve of freezing compartment 306, L3 is complete machine operation.Monosystem System wind cooling refrigerator, during compressor booting, in order to guarantee 302 temperature of refrigerator room and avoid evaporimeter frosting too fast, one As way be refrigeration prior to freezing refrigeration terminate.This creates the terminal a period of times of freezing separate refrigeration, to produce (2) State, refrigerator room air door 308, alternating temperature compartment air door 310 are closed, but are freezed blower 312 and also opened, and are stopped until freezing reaches Blower is freezed after machine point to close with compressor.(2) state is to cause the major reason of refrigerator room condensation, and with the time Extend, condensation can be accumulated increasingly severe.

Since cannot stop freezing blower 312 to guarantee freezing refrigeration, then freezing 312 revolving speed of blower is taken to be directed to respectively (1) state, (2) state, are controlled using different rotation speed of fan, and under (1) state, freezing blower 312 uses higher turn Speed carries out and (former revolving speed can be used to carry out), and under (2) state, freezing blower 312 is carried out using compared with the slow-speed of revolution (relative to former revolving speed Revolving speed is reduced).

The case where ensure that 306 separate refrigeration of freezing compartment as a result, and alleviating 302 negative pressure of refrigerator room.The reason is that (2) under state, freezing 312 revolving speed of blower is reduced, and can reduce refrigerator room 302, the suction of return air in alternating temperature compartment 304 is made With so that refrigerator room 302, the reduced pressure in alternating temperature compartment 304 are reduced, to fundamentally reduce refrigerator room 302, become A possibility that warm 304 gallbladder side condensation of compartment.

(2) refrigerator room 302 under state, the pressure in alternating temperature compartment 304 are unable to < -0.5Pa, which is according to improvement Program is applied in condensation experiment, is met the numerical value of condensation experiment qualification, the safety that analog subscriber uses, is using this hair The quantization test method that bright embodiment proposes, and the countermeasure obtained from quantization method are applied in process control and then logical Cross condensation experiment and user's simulated experiment verifying as a result, this be also the embodiment of the present invention generate core criterion.

3. be directed to (3) state, refrigerator room air door 308 be open, alternating temperature compartment air door 310 is pass, Fig. 7 shows the state Under each compartment negative pressure condition, refrigerator room 302 is positive pressure, alternating temperature compartment 304 is negative pressure, freezing compartment 306 is positive pressure.

Under the state, alternating temperature compartment 304 is likely to occur negative pressure, it is also possible to be not in that this is with refrigerator room 302 to alternating temperature The influence size of compartment 304 is related.

For refrigerator room 302 and alternating temperature compartment 304 in same case courage, divided simply by foam or glass partition From refrigerator, do not accomplish to seal well between refrigerator room 302 and alternating temperature compartment 304, air-flow can pass through partition perimetric penetration To another compartment.Pressure can reach unanimity in the case of refrigerator room 302 and alternating temperature compartment 304.Since refrigeration is far longer than alternating temperature, So alternating temperature compartment 304 influenced by refrigerator room 302 it is very big.Even if therefore alternating temperature compartment air door 310 is closed, it is also possible to because The powerful influence power that refrigerator room air door 308 is opened, and occur in alternating temperature compartment 304 also with refrigerator room 302 being positive pressure shape State.

The case where distinguishing two independent liners for refrigerator room 302 and alternating temperature compartment 304, alternating temperature compartment 304 may There is negative pressure.In this case, when be negative pressure and refrigerator room air door 308 of alternating temperature chamber pressure is open state, alternating temperature compartment wind When door 310 is in off state, the revolving speed of the freezing blower 312 of refrigerator is reduced.

4. (4) state of being directed to, refrigerator room air door 308 is pass, alternating temperature compartment air door 310 is to open, and Fig. 8 shows the state Under each compartment negative pressure condition, refrigerator room 302 is negative pressure, alternating temperature compartment 304 is positive pressure, freezing compartment 306 is positive pressure.

For refrigerator room 302 and alternating temperature compartment 304 in same chamber (such as alternating temperature compartment 304 be refrigerator room 302 Interior drawer), the state is similar with (2) state, and refrigerator room air door 308 closes, it will lead to negative pressure in refrigerator room 302 certainly, and Although alternating temperature compartment air door 310 is opened, it is also possible to which powerful by refrigerator room 302 influences, and negative pressure occurs.Therefore, regardless of alternating temperature Which kind of state compartment air door 310 is in, and is subject to 308 open and-shut mode of refrigerator room air door, and freezing blower is reduced from program 312 voltage and revolving speed.

It is independent liner for refrigerator room 302 and alternating temperature compartment 304, in the case where mutually indepedent, refrigerator room air door 308 close, and do not influence on alternating temperature compartment 304.Therefore, when (4) state refrigerator room air door 308 closes, alternating temperature compartment air door 310 is When opening, if negative pressure occurs in alternating temperature compartment 304, need to increase the air-supply air quantity of alternating temperature compartment 304.

For above-mentioned analysis, regulation measure in detail below is provided:

1. in the case of refrigerator room 302 and alternating temperature compartment 304 are in same case courage, between refrigerator room 302 and alternating temperature Pressure can reach unanimity in the case of room 304, the switch state with refrigerator room air door 308 be it is leading, as shown in table 1, (1) state (3) when state, 302 negative pressure of refrigerator room then changes R air-supply (increasing the air-supply air quantity of refrigerator room 302), alternating temperature compartment 304 Then change R air-supply for negative pressure and change S air-supply (increasing the air-supply air quantity of alternating temperature compartment 304), freezing compartment 306 is that negative pressure then changes F return air (the return air air quantity for reducing freezing compartment 306)；(2) when state and (4) state, 302 negative pressure of refrigerator room then selects cold Jelly blower 312 is 7V voltage (reducing the revolving speed of freezing blower 312), and alternating temperature compartment 304 is that negative pressure then selects freezing blower 312 For 7V voltage, freezing compartment 306 is that negative pressure then changes F return air.

2. the case where distinguishing two independent liners for refrigerator room 302 and alternating temperature compartment 304, refrigerator room 302 and change Pressure is different in the case of warm compartment 304, needs according to the switch state of refrigerator room air door 308 and alternating temperature compartment air door 310 Switch state is adjusted, and as shown in table 2, when (1) state, 302 negative pressure of refrigerator room then changes R air-supply, alternating temperature compartment 304 be negative pressure then Change R air-supply and change S air-supply, freezing compartment 306 is that negative pressure then changes F return air；(2) when state, 302 negative pressure of refrigerator room is then selected Freezing blower 312 is 7V voltage, and alternating temperature compartment 304 is that negative pressure then selects to freeze blower 312 to be 7V voltage, and freezing compartment 306 is Negative pressure then changes F return air；(3) when state, 302 negative pressure of refrigerator room then changes R air-supply, and alternating temperature compartment 304 is that negative pressure then selects to freeze Blower 312 is 7V voltage, and freezing compartment 306 is that negative pressure then changes F return air；(4) when state, 302 negative pressure of refrigerator room then selects cold Jelly blower 312 is 7V voltage, and alternating temperature compartment 304 is that negative pressure then changes S air-supply, and freezing compartment 306 is that negative pressure then changes F return air.

It should be noted that 9V is the voltage that must survey for freezing blower 312,7V is the choosing survey voltage for freezing blower 312, changes R Blowing, change F return air, changing S air-supply is also that choosing is surveyed.
