Fig. 2 is the structural representation of the connection status of the embodiment of the invention two.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.
Embodiment one
As shown in Figure 1,
It is a Multi-split cold and warm air conditioner, comprises that cross valve 2 that compressor 1, a end, c end be communicated with compressor, an end and the b of cross valve hold the condenser 3, first evaporimeter 10, second evaporimeter 12, first magnetic valve 11, second magnetic valve 13 that are communicated with, heat capillary 5, refrigerating capillary 7, first check valve 4, second check valve 6, the 3rd check valve 8 and the 4th check valve 9.First evaporimeter is connected mutually with first magnetic valve and is constituted first tandem arrangement, and second evaporimeter is connected mutually with second magnetic valve and constituted second tandem arrangement, two tandem arrangements formation shunting means in parallel mutually.In the present embodiment, heat capillary 5 and constitute the 3rd tandem arrangement with first check valve, 4 mutual series connection, the refrigerating capillary 7 and second check valve 6 are connected mutually and are constituted the 4th tandem arrangements; The 3rd tandem arrangement, the 4th tandem arrangement, the 3rd check valve 8 and the 4th one-way cock 9 constitute the bridge-type throttle system; Their connected mode is, the port of export of the 3rd tandem arrangement all is communicated with the other end of condenser 3 with the arrival end of the 4th tandem arrangement, the port of export of the 4th tandem arrangement is communicated with the arrival end of shunting means, the port of export of the 3rd check valve 8 also is communicated with this port of shunting means, the arrival end of the 3rd check valve 8 is communicated with the d of cross valve end, the arrival end of the 3rd tandem arrangement is communicated with the port of export of shunting means, the arrival end of the 4th check valve 9 also is communicated with this port of shunting means, and the port of export of the 4th check valve 9 is communicated with the d of cross valve end.First check valve 4, second check valve 6, the 3rd check valve 8 and the 4th check valve 9 in the present embodiment all can be magnetic valve.
During work, when air-conditioning refrigeration system carries out refrigerating operaton, high-temperature high-pressure refrigerant from condenser is through second check valve 6, refrigerating capillary 7, divide two-way through first magnetic valve 11, first evaporimeter 10 and second magnetic valve 13, second evaporimeter 12, get back to compressor 1 through the d of the 4th check valve 9, cross valve end again.If second evaporimeter 12 does not need refrigeration, then second magnetic valve 13 cuts out, and second evaporimeter, 12 no cold-producing mediums flow through, and can not retain cold-producing medium and lubricating oil, and this one drags many air-conditionings scheme identical with other.When air-conditioning refrigeration system carries out heating operation, high-temperature high-pressure refrigerant process cross valve, the 3rd check valve 8 from compressor 1, divide two-way through first magnetic valve 11, first evaporimeter 10 and second magnetic valve 13, second evaporimeter 12, again through first check valve 4, heat capillary 5, condenser 3, cross valve 2, get back to compressor 1.If second evaporimeter 12 does not need to heat, then second magnetic valve 13 disconnects, and evaporimeter 2 no cold-producing mediums flow through, and can not retain cold-producing medium and lubricating oil.
As shown in Figure 2, other the same with embodiment one, different is is replaced with first electric expansion valve 14 with the capillary 5 that heats of embodiment one, and refrigerating capillary 7 is replaced with second electric expansion valve 15; Working method is the same with embodiment one, no longer describes in detail.
