At this time, the first port 8a of the three-way switching threshold 8 connected to the indoor eaves B and C is a closed circuit, and the second port 8b and the third port 8c are open circuits. The second port 8b of the indoor unit D is a closed circuit, and the first port 8a and the third port 8c are two channels. At this time, the first connection piping 6 is low pressure, and the second connection piping 7 is depressurized, so the refrigerant must circulate to the third check valve 32 and the fourth check valve 33.

Description of invention (26) Control method of setting 9. In the first embodiment, according to the preset target temperature of the indoor eaves and the temperature difference At iSta_t0 of the sensing temperature ta of the suction air temperature sensing device 50, the following three values are set to a minimum of two degrees. The first minimum opening degree is 1. When the temperature difference At is At 2 t2, the rated cooling capacity is required for the indoor unit. Therefore, in this case, the gambling degree control is performed in accordance with the superheat degree SH at the outlet of the indoor heat exchanger 5. That is, when the target superheat degree SH «m outlet meets the heat SH employment difference ASHeSH-SH» preset to the indoor unit is ASH> 0, it is determined that the amount of refrigerant is insufficient, and the opening degree is increased. Conversely, if ASH &lt; 0, it is judged that the amount of refrigerant is excessive, and the opening degree is reduced. In addition, when △ SH = 0, it is determined that the amount of refrigerant is an appropriate amount, and the opening degree is maintained. The second minimum valve opening degree S «m is set to be smaller than the first minimum valve opening degree S» 1 when the temperature difference tl ≦ At &lt; t2. This is because the cooling capacity required for the indoor unit does not have to be the same as in the case of At 2t2, as long as the refrigerant that matches its capacity meets. That is, in this case, when only the first minimum valve opening degree S «1 is set and the opening degree control is performed with excessive heat, due to the large amount of refrigerant, the resulting cooling capacity is not balanced with the required cooling capacity, resulting in The indoor unit repeatedly turned and stopped, which not only disturbed the stability of Xun Chen, but also impaired the comfort due to the blowing of the cold wind following the mine. Therefore, as described above, the second value is set to be two times smaller, S »2, to reduce the opening degree at a predetermined ratio, by which the appropriate opening degree can be set so that the amount of refrigerant that meets the required capacity flows. The opening should be smooth and gentle, without «randomly chasing Chen's stability.

Description of invention ( 32) For example, in a state where the indoor unit D is performing the air blow and the indoor units B and C are operating as the air conditioner, the three flow paths such as the indoor unit B, C and the third flow control device 15 are juxtaposed to become the flow of the air-conditioning lotus part road. Here, when the indoor unit B stops the lotus rotation, since the first flow control device 9 of the indoor eaves B is fully closed, the flow path becomes the second flow path of the indoor unit C and the third flow control device 15. As the flow path decreases, the pressure of the refrigerant changes, and the low pressure drops, and the refrigerant circulation becomes disordered. Therefore, when the indoor unit B stops the lotus rotation, the valve opening of the third flow control device 15 is increased to increase the flow rate, so that the refrigerant flowing through the indoor unit B flows to the third flow control device 15 at The first, second, and third heat exchange sections 16a to 16d, and 19 allow it to evaporate. Second, in the state where the indoor unit D is turned into a warm air vine, the indoor eaves B is stopped, and the indoor eaves C is turned into an air-conditioned lotus, the indoor The two flow paths such as the machine C and the third flow * control device 15 are parallel to become the flow path of the air-conditioning operation part. When the indoor unit B starts the air-conditioning lotus turn, since the first flow control device 9 of the indoor unit B starts drinking, the flow path becomes three flow paths such as the indoor units B, C and the third flow control device 15. As the flow path increases, the pressure of the refrigerant changes and the low pressure rises, causing the refrigerant to become chaotic. Therefore, when the indoor unit B starts to operate, the valve opening of the third flow suspension control device 15 is reduced to reduce the flow rate, and a part of the refrigerant originally flowing through the third flow control device 15 flows through Indoor unit B 〇Secondly, referring to the flow chart of the tenth circle, the content of the control of the third flow control device 15 by the third valve opening degree control device 54 in the case where the cold air is turning at the same time as the cold air is mainly turning . -36-(Please read the precautions on the back before filling out this page) 丨 Fork-Ishimoto's paper standard for easy use S Β Family Standard (CHS) A 4 specifications (210X297 male dragon) 5 10 15 Employees of the Central Bureau of Economic Affairs Printed by the consumer cooperative '0 丄 D .u A 6 __B_6 V.

In Embodiment 5 described above, only the cooling or heating operation operation, the lotus turning operation of the hot air main snakehead, and the lotus turning operation of the cold air main pus are performed in the same manner as in the first embodiment above. Next, the control of the first flow control device 9 by controlling the eaves structure 55 when the indoor unit that is performing heating or cooling operation is stopped. First, when the heating is being built (cool air delay) When a stop condition occurs in the indoor unit, it is controlled so that the opening degree of the first flow control device 9 does not suddenly become the closed state. This is because if the condensing capacity of the indoor unit to be stopped (evaporating capacity in air-conditioning operation) suddenly disappears, the depressurizing pressure of the air-conditioning device (in cold air, "low-pressure K-force during rotation") rises extremely (in air-conditioning Medium to reduce), and it will cause the temperature of the heat exchanger of the indoor unit in other heating lotus turn (cold air S turn) to increase excessively (frozen in the air conditioner turn) or the compression of the eaves and other problems. Therefore, in the fifth embodiment, in the case where indoor heating is being stopped (air-cooled lotus rotation), the fourth valve opening degree control device 56 will divide the opening degree Pa immediately before the stop by the predetermined value The opening P obtained by the coefficient A (the coefficient B when the air conditioner turns) is rounded out.

Description of the invention (57) In the case where only the air conditioner is turned, where only the warm air is operated, and where the air conditioner and the heating and cooling are simultaneously turned to the main gas, the above example 15 The operation is the same as in the first embodiment described above. Next, the operation in the case where the cold air is turned simultaneously with the main air conditioner is explained. When the liquid level of the interface between the gaseous refrigerant and the liquid refrigerant separated in the gas-liquid separation device 12 is lower than the liquid discharge tube 37 of the gas-liquid separation device 12, the gaseous refrigerant flows into the liquid waist discharge tube 37, The sixth flow control device 38 is reduced to a low pressure. Since the inlet of the sixth flow control device 38 is in a gaseous state, there is less refrigerant flowing through the sixth flow * control device 38. Therefore, the refrigerant flowing through the liquid K discharge pipe 37 exchanges heat with the high-pressure gaseous refrigerant flowing into the first bifurcating portion 10 from the gas-liquid separation device 12 in the fourth heat exchange portion 39, and becomes a low-pressure superheated haze, which flows into First connection piping 6. Conversely, when the liquid surface of the block of the gaseous refrigerant and the liquid refrigerant separated in the gas-liquid separation device 12 is further away from the liquid discharge pipe 37 of the gas-liquid separation device 12, the liquid refrigerant flows into the liquid discharge pipe 37, At the sixth flow, the control device 38 is stepped down to a low pressure. Since the inlet of the sixth flow control device 38 is in a liquid state, the refrigerant flowing through the sixth flow control device 38 is more often than the case where the inlet is in a gaseous state. Therefore, even if the refrigerant flowing through the liquid discharge pipe 37 exchanges heat with the high-pressure gaseous refrigerant flowing into the first branch portion 10 from the gas-liquid separation device 12 in the fourth heat exchange portion 39, it will not become a low-pressure superheated gas. , And flows into the first connection pipe 6 in a two-phase state. The S-heat state of the low-pressure refrigerant that is subjected to heat exchange in the fourth heat exchange unit 39 is based on the pressure detected by the third fi force sensing device 46 and the fifth temperature sensing device 82 -61-A 6 B6 (Please read the precautions on the back before writing this page.)

Description of the invention (67) Therefore, heating and cooling can be selectively applied, and cold air can be applied to one indoor unit and« gas to another indoor eaves simultaneously. In addition, during the cooling operation, after the first and second heat exchange elements of the heat source unit side heat exchanger are condensed by heat exchange, the third heat exchange element is again used for heat exchange by the switching device. Even if the heat exchange between the first and second heat exchange elements is not balanced, it can also be fully condensed. Because the liquid refrigerant can fully obtain the cooling degree before being distributed to the indoor unit, the liquid refrigerant can be changed to Distributive. In addition, when the defrosting lotus is turned, after the first and second heat exchange elements of the heat source machine's cooked heat exchangers are condensed for defrosting, the third heat exchange element is again used for heat exchange using a switching device. In this way, even if the defrosting of the first and second heat exchange elements is uneven due to uneven frosting, the heat source unit side heat exchanges before all of the first to third heat exchange elements are fully deboxed The temperature of the refrigerant at the outlet of the heater does not rise, so it can prevent the situation that frost remains and the defrost surface has been terminated, and it can prevent the insufficient gas capacity caused by the heating of the lotus when the frost is left.
