According to one embodiment of present invention, also comprised before described step 102: according to the setting command received, described Preset Time is set.
In this technical scheme, the comfort level that user can experience according to self arranges adjustment Preset Time, wherein, preferably, and 8 minutes≤Preset Time≤25 minute.
Below in conjunction with Fig. 2 and Fig. 3, drag machine in two duplicate 12K (interior machine A, interior machine B) for the outer machine of 12K, describe technical scheme of the present invention in detail.
Fig. 2 shows the structural representation sketch of fixed according to an embodiment of the invention one drag two air-conditioning frequently.
As shown in Figure 2, when singly opening indoor set A, now magnetic valve B closes, kind of refrigeration cycle exhaust from compressor 01 out through cross valve 02 to condenser 03, then shunt selection through throttle part 04 and diversion three-way b06 and walk magnetic valve A08, enter indoor set A evaporimeter 09, finally get back to compressor 01 through cross valve 02 again, complete a kind of refrigeration cycle; Under heating mode, refrigerant circulates against road.
When singly opening indoor set B, now magnetic valve A closes, and refrigerant circulation is with reference to the mode singly opening indoor set A.
When indoor set A and indoor set B with open time, control mode follow following some: 1, between two indoor sets mode prioritization order for heating, freezing, dehumidify; Heat and freeze, dehumidify and conflict, can not with opening; Heat, freeze, the Three models that dehumidifies can with air supply pattern with opening.
Particularly, indoor set A and indoor set B is with when opening, and the control method of fixed one drag two air-conditioning frequently as shown in Figure 3 and Figure 4.
Wherein, as shown in Figure 3, when the start signal received is cooling signals, the idiographic flow of the fixed control method of one drag two air-conditioning frequently comprises:
Step 302, when two indoor sets all receive cooling signals, detects ambient temperature value T1a and the set temperature value Tsa of indoor set A at once, and indoor set B ambient temperature value T1b and set temperature value Tsb.
Step 304, judges whether T1a-Tsa >=T1b-Tsb, when judged result is for being, enters step 306, otherwise, enter step 312.
Step 306, open electromagnetic valve A, close magnetic valve B, indoor set A freezes.
Step 308, judging whether meet T1a-Tsa≤0 within time Tx, when judged result is for being, entering step 310, otherwise, return step 304.
Step 310, closes magnetic valve A, open electromagnetic valve B, now change indoor set B to work, the condition of T1a-Tsa≤0 can not be reached within Tx, again detect and judge that the value of T1a-Tsa and T1b-Tsb is as the basis selecting which indoor set work, then entering the next time Tx cycle.
Step 312, open electromagnetic valve B, close magnetic valve A, indoor set B freezes.
Step 314, judging whether meet T1b-Tsb≤0 within time Tx, when judged result is for being, entering step 316, otherwise, return step 304.
Step 316, closes magnetic valve B, open electromagnetic valve A, now change indoor set A to work, the condition of T1b-Tsb≤0 can not be reached within Tx, again detect and judge that the value of T1a-Tsa and T1b-Tsb is as the basis selecting which indoor set work, then entering the next time Tx cycle.
Step 318, if T1a-Tsa≤0 and T1b-Tsb≤0 in certain period, then complete machine enters and reaches warm stopped status, comprises and stops outer machine.Wherein, the comfort level that user can experience according to self arranges and regulates Tx, preferably, and 8min≤Tx≤25min.
Wherein, as shown in Figure 4, when the start signal received is cooling signals, the idiographic flow of the fixed control method of one drag two air-conditioning frequently comprises:
Step 402, when two indoor sets all receive and heat signal, detects ambient temperature value T1a and the set temperature value Tsa of indoor set A at once, and indoor set B ambient temperature value T1b and set temperature value Tsb.
Step 404, judges whether Tsa-T1a >=Tsb-T1b, when judged result is for being, enters step 406, otherwise, enter step 412.
Step 406, open electromagnetic valve A, close magnetic valve B, indoor set A heats.
Step 408, judging whether meet T1a-Tsa >=0 within time Tx, when judged result is for being, entering step 410, otherwise, return step 404.
Step 410, closes magnetic valve A, open electromagnetic valve B, now change indoor set B to work, the condition of T1a-Tsa >=0 can not be reached within Tx, again detect and judge that the value of T1a-Tsa and T1b-Tsb is as the basis selecting which indoor set work, then entering the next time Tx cycle.
Step 412, open electromagnetic valve B, close magnetic valve A, indoor set B heats.
