Embodiment Construction

[0032] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] refer to figure 2 , which is a schematic diagram of an embodiment of the heat exchange system for a single-unit air conditioner proposed by the present invention.

[0034] refer to figure 2 As shown, the single-unit air conditioner heat exchange system of this embodiment has an indoor heat exchanger 1, an outdoor heat exchanger 4, a compressor 11, two throttling devices 12 and 13, and two four-way reversing valves 8 and 9. Wherein, the indoor heat exchanger 1 is divided into two parts, namely an indoor sub-heat exchanger 2 and an indoor sub-heat exchanger 3 . Correspondingly, the outdoor heat exchanger 4 is also divided into two parts: an outdoor sub-heat exchanger 5 and an outdoor sub-heat exchanger 6 . Moreover, the indoor sub-heat exchanger 2, the outdoor sub-heat exchanger 5, the throttling device 12 and the four-way reversing...

Abstract

The invention discloses a heat exchange system of a single air conditioner as well as the single air conditioner and a control method thereof. The heat exchange system comprises an indoor heat exchanger, an outdoor heat exchanger and a compressor, wherein the indoor heat exchanger is divided into at least two secondary indoor heat exchangers; the outdoor heat exchanger is divided into secondary outdoor heat exchangers with the quantity which is the same as that of the secondary indoor heat exchangers; the heat exchange system is further provided with throttling devices and four-way reversing valves with the quantities which are the same as the quantity of the secondary indoor heat exchangers; a heat exchange module is composed of one secondary indoor heat exchanger, one secondary outdoor heat exchanger, one throttling device and one four-way reversing valve; all the heat exchange modules are connected with the compressor at the same time. According to the heat exchange system of the single air conditioner disclosed by the invention, the heat exchange system is divided into the plurality of heat exchange modules so that the independent control on the heat exchange modules is realized and the refrigeration of one part of the heat exchange modules and the heating of the residual heat exchange modules are realized, and furthermore, functions of dehumidifying at a constant temperature, defrosting continuously by heating, outputting refrigeration or heating at a constant temperature and the like are realized.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a heat exchange system of a single-unit air conditioner, a single-unit air conditioner with the heat exchange system, and a control method for the single-unit air conditioner. Background technique [0002] Current stand-alone air conditioners, such as figure 1 As shown, it is composed of compressor 20, indoor heat exchanger 21, outdoor heat exchanger 22, four-way reversing valve 23, throttling device 24 and other components. Wherein, one port of the indoor heat exchanger 21 is connected to the throttling device 22, and then connected to a port of the outdoor heat exchanger 22 through the throttling device 22, and the other port of the indoor heat exchanger 21 is connected to the four-way reversing valve. The third valve port E of 23 is connected; the other port of the outdoor heat exchanger 22 is connected with the first valve port C of the four-way reversing valve 23 ....
