Embodiment Construction

[0021] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0022] see Figure 1 to Figure 3 , according to the air conditioning system of the present invention, comprising a compressor 10, an indoor heat exchanger 20 and an outdoor heat exchanger 30 connected in sequence; the outdoor heat exchanger 30 includes a first outdoor heat exchanger 31 and a second outdoor heat exchanger 32; The 2 to 3 U pipes of the subcooling section of the outdoor heat exchanger 30 can be separated into the heating part in the present invention—that is, the second outdoor heat exchanger 32 . It also includes a throttling guide assembly, which is arranged between the indoor heat exchanger 20 and the outdoor heat exchanger 30. The throttling guide assembly controls the high-temperature gaseous refrigerant to enter the first outdoor...

Abstract

The present invention provides an air-conditioning system, which includes a throttling guide assembly, which is arranged between an indoor heat exchanger and an outdoor heat exchanger. The throttling guide assembly controls the high-temperature gaseous refrigerant to selectively circulate the refrigerant in different modes. Distribution, entering different heat exchangers; when cooling, the throttling guide assembly makes the refrigerant pass through the first outdoor heat exchanger and the second outdoor heat exchanger successively and then throttling; when heating, the throttling guide assembly diverts the refrigerant , part of the refrigerant enters the first outdoor heat exchanger, part of it enters the second outdoor heat exchanger, and finally all the refrigerant enters the first outdoor heat exchanger; the first port of the first outdoor heat exchanger is connected to the compressor, and the first outdoor heat exchanger The second port of the heat exchanger communicates with the throttling guide assembly; both the first port and the second port of the second outdoor heat exchanger communicate with the throttling guide assembly, and the second port of the second outdoor heat exchanger is simultaneously connected to to the piping between the compressor and the indoor heat exchanger. Solved the problem of frosting when heating.

Description

technical field [0001] The present invention relates to the field of air conditioning, in particular to an air conditioning system. Background technique [0002] Defrost is a more serious problem faced by heat pump machines at present. Frosting affects the stable operation of the air conditioner; the conventional defrosting method is to switch the cooling mode, stop the internal fan, and the indoor temperature will drop, which has a great impact on user comfort. From the system direction, it is very important technical design to reduce frosting and optimize defrosting effect. [0003] There are generally two directions to improve heat pump technology: one is to speed up defrosting; the other is to reduce frosting. The amount of frosting can be reduced by improving the hydrophilicity of the fins of the heat exchanger and increasing the heat exchange area of ​​the heat exchanger. However, further designs may require additional external heat sources (bypass defrosting, retur...
