It is below specific embodiment by the multi-line system of core of cold-storage, the control of multi-line system is described in further detail
Method processed.Thermal insulation pool 3 in the specific embodiment is cold accumulating pond.
1) control of outdoor unit 1
Start multi-line system;
Set the target temperature Tb of cold accumulating pond;
The temperature Ta of real-time detection cold accumulating pond;
It further, is temperature sensor, temperature sensor every five seconds detection one set on the first temperature-sensing element 7 of cold accumulating pond
(temperature sensor is usually that 5s feeds back a data to the temperature Ta of secondary cold accumulating pond, is then 10s if there is remote data transmitting
Feed back a data);
△ T1=Ta-Tb is calculated in real time;- 2 DEG C of T1 value, 5 DEG C of T2 value.
T1 >=5 DEG C △ if (T2);Outdoor unit 1 is then opened, is divided between the unlatching of each main computer unit 11 of outdoor unit 1
1min (this be in the identical situation of refrigerating capacity of each main computer unit 11, if the refrigerating capacity of each main computer unit 11 is different,
Then separately adjust opening interval), to reduce the water temperature in cold accumulating pond as early as possible.
If -2 DEG C of 5 DEG C of (T1)≤△ T1 < (T2);Current state is then kept, the main computer unit 11 having turned on keeps fortune
Row is not opening remaining main computer unit 11.
If < -2 DEG C of △ T1 (T1);Then close outdoor unit 1, the off-interval of each main computer unit 11 of outdoor unit 1
For 1min (if in shutdown process, suddenly again meet condition one, i.e. T1 >=5 DEG C △, then no longer close main computer unit 11, and according to
Condition one acts).
The value range of △ T1 be it is empirically determined, above-mentioned temperature gap section is recommendation, it is assumed that the target temperature of cold accumulating pond
Tb=7 DEG C, then the existing of outdoor unit 1 can be kept when the temperature Ta of real-time detection cold accumulating pond runs to 5 DEG C~12 DEG C
State, that is, the main computer unit 11 having turned on remain operational, and the main computer unit 11 of closed state remains turned-off.
5 DEG C of -2 DEG C≤△ T1 <, the water temperature within the scope of this are very nice and cool for user.If the target of certain cold accumulating pond
Temperature Tb there is a situation where too high or too low, then can do certain change adjustment.
2) control of indoor units 2
Start multi-line system, after making T1≤△ T1 < T2 for the first time, carries out water between thermal insulation pool 3 and indoor units 2 and follow
Ring;Alternatively, water pump is opened after starting multi-line system 3min, water circulation is carried out between thermal insulation pool 3 and indoor units 2.
Above-mentioned 3min is recommendation, and after this time value, general water circuit system has been able to accomplish balancing water temperature, i.e.,
T1≤△ T1 < T2.
Indoor target temperature set by user is Tk.
The each terminal room temperature Ts of real-time detection.
The detection of room temperature Ts can use temperature sensor, and temperature sensor every five seconds detects a room temperature Ts
(temperature sensor is usually that 5s feeds back a data, is then that 10s feeds back a data if there is remote data transmitting).
△ T4=Ts-Tk is calculated in real time.- 1 DEG C of T3 value, 2 DEG C of T4 value.
If T4 >=2 DEG C △ (T4), opening interior machine terminal 21, (interior machine terminal 21 is installed on interior, and independent control opens
Stop).
If -1 DEG C of 2 DEG C of (T3)≤△ T4 < (T4), current state is kept, interior machine terminal 21 keeps transporting if having turned on
Row, interior machine terminal 21 are not opened, are remained turned-off.
If < -1 DEG C of △ T1 (T3), interior machine terminal 21 is closed.
Each interior 21 independent control of machine terminal, each interior machine terminal 21 reach condition one (T4 >=2 DEG C △ (T4)) and are switched on;Reach
Condition two (- 12 DEG C of (T3)≤△ T4 < (T4)) is kept;Reach condition three (- 12 DEG C of (T3)≤△ T4 < (T4)) closing.
△ T4 is room temperature control deviation, if user sets 26 DEG C of demand, is greater than 28 DEG C and is switched on interior machine end
End 21, standing state is maintained at 25 DEG C~28 DEG C, and (the interior unlatching of machine terminal 21 is then kept it turning on, and the interior closing of machine terminal 21 is then kept
It closes).In the range of user sets 3 DEG C of temperature difference up and down, interior machine terminal 21 will not frequent start-stop, users'comfort can also protect
Card.
3) control of cold accumulating pond flow
After carrying out water circulation between cold accumulating pond and indoor units 2, the water outlet of real-time detection indoor units 2 and cold accumulating pond
Return water temperature Tc on the pipeline of connection.The every 5s detection primary water temperature Tc of temperature sensor can be used.
△ T2=Tc-Tb is calculated in real time;
The real-time traffic control formula of flow control valve is as follows:
Wherein, △ T3 is specified terminal heat transfer temperature difference, and H=Q*0.143 is specified interior machine total water current amount;Q is outdoor unit
All load output quantities of group 1.
