[0077] figure 2 It is a schematic diagram which shows the circuit structure of 1 A of air-conditioning apparatuses concerning Embodiment 2 of this invention. The air conditioner 1A of the present embodiment is basically the same in structure as the air conditioner 1 of the above-mentioned first embodiment, and here, the same symbols as those of the above-mentioned first embodiment are assigned the same symbols, and the differences from the above-mentioned first embodiment are designated by the same reference numerals. The center is described.

[0078] In this embodiment, if figure 2 As shown, the outdoor unit 100' includes a four-way switching valve V1 as a first switching device. Switching between a switching state and a second switching state in which the four-way switching valve V1 communicates the first pipe P1 with the suction pipe PI and connects the second pipe P2 with the discharge pipe PO, in which In the second switching state, the four-way switching valve V1 co...

Embodiment approach 3

[0089] image 3 It is a schematic diagram which shows the circuit structure of the air-conditioning apparatus 1B which concerns on Embodiment 3 of this invention. The air conditioner 1B of this embodiment is basically the same in structure as the air conditioner 1A of the above-mentioned second embodiment, and here, the same symbols as those of the above-mentioned second embodiment are attached with the same symbols, and the differences from the above-mentioned second embodiment are assigned. The center is described.

[0090] In this embodiment, if image 3 As shown, the outdoor unit 100" of the air conditioner 1B includes a branch pipe P5, a branch pipe P6, a throttling device V4, and a four-way switching valve V3 as a second switching device. Here, the branch pipe P5 starts from the suction Tube PI image 3 In the point K6 branch out, the branch pipe P6 is from the branch pipe P5 image 3 The point K3 is branched out, the throttling device V4 is arranged on the branch pi...

Abstract

An air conditioner includes an outdoor unit and a dehumidifying and reheating indoor unit, is capable of avoiding non-uniform temperature distribution of airflow supplied to the indoor by the dehumidifying and reheating indoor unit, and gives full play to the functions of a dehumidifying heat exchanger and reheating heat exchanger of the dehumidifying and reheating indoor unit. According to the air conditioner, the outdoor unit includes a compression mechanism and an outdoor heat exchanger, the dehumidifying and reheating indoor unit includes a dehumidifying heat exchanger and a first indoor refrigerant regulating device, the air conditioner utilizes a suction pipe, a discharge pipe, a first matched pipe and a second matched pipe to connect the compression mechanism, the outdoor heat exchanger, the first indoor refrigerant regulating device and the dehumidifying heat exchanger, the air conditioner also comprises a reheating heat exchanger, a second indoor refrigerant regulating device,a third matched pipe and a branch pipe, the third matched pipe sequentially connects a first junction portion of the first matched pipe, between the first indoor refrigerant regulating device and theoutdoor heat exchanger, the second indoor refrigerant regulating device, the reheating heat exchanger, and the branch pipe.

Description

[0001] This application is a divisional application of the invention patent application with the application number "201410059992.5" and the name "air-conditioning device" submitted by the applicant on February 21, 2014. technical field [0002] The present invention relates to air conditioners. Background technique [0003] With the improvement of people's living standards, people's demand for living environment control has become increasingly prominent. Therefore, the function of air-conditioning devices has gradually developed from a single temperature adjustment to a diversified development. In humid and rainy areas and during the rainy season, the humidity of the air is relatively high, causing discomfort to the human body. Therefore, an air conditioner with a humidity control function has emerged as the times require. [0004] Air conditioning units typically dehumidify by passing air through a heat exchanger whose surface temperature is below the dew point of the air,...
