Problems solved by technology

[0003] However, since this type of air conditioner cannot prevent heat release from the heat release heat exchanger even during the cooling operation, the efficiency during the cooling operation is not high.
In addition, in order to increase the capacity of the air conditioner, the diameter of the piping through which the liquid refrigerant flows can be increased, but this will increase the difference between the optimal refrigerant amounts for cooling operation and dehumidification operation (reheat dehumidification operation), so Reduced efficiency of the entire air conditioning unit

Embodiment Construction

[0011] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0012] Fig. 1 is a schematic structural diagram of an air conditioner. The air conditioner 1 is configured by connecting an outdoor unit 2 and an indoor unit 3 through pipes 4 and 5 .

[0013] The discharge pipe 11 connected to the discharge port of the compressor 10 in the outdoor unit 2 is connected to the inlet of the outdoor heat exchanger 12 . The pipe 4 is connected to the outlet of the outdoor heat exchanger 12, and the pipe 4 is provided with the first decompression device 13 on its route, and then extends to the indoor unit 3 side.

[0014] The indoor unit 3 has a first heat exchanger 21 and a second heat exchanger 22, and the first heat exchanger 21 and the second heat exchanger 22 are arranged almost in parallel in the order of the second heat exchanger 22 and the first heat exchanger 21 On the airflow path (indicated by arr...

Abstract

The present invention provides an air conditioner capable of performing refrigeration process and a reheated dehumidification process effectively. In the air conditioner 1 in accordance with the invention, a first heat exchanger 21 and a second heat exchanger 22 are arranged in turn in the passage A of air current circulating in the indoor machine 3. A distribution pipe 24 extending from an outflow port 21B in the lower part of the first heat exchanger 21 extends upward, provided with a 'U' shape branching part 25, and is then connected to a liquid reservoir 26. A two-way valve 28 provided on a distribution pipe 27 connected to said liquid reservoir is connected to an inflow port 22A linked to the second heat exchanger 22. A prolonging distribution pipe 29 which is linked to a projecting portion on the upside of the branching part 25 is provided with a second decompressor 30 and then connected to the inflow port 22A of the second heat exchanger 22.

Description

technical field [0001] The present invention relates to an air conditioner capable of cooling operation and dehumidification operation. Background technique [0002] There is an air conditioner called a dehumidification-only reheat dehumidification air conditioner that can switch between dehumidification cooling operation and dehumidification heating operation. The indoor unit of this air conditioner has the indoor unit connected in series with a heat exchanger for dehumidification, a decompression device, a refrigerant liquid reservoir and a heat exchanger for heat release, as in Japanese "Patent Publication No. 2002-60930". The accumulator is used to store surplus liquid refrigerant in the liquid refrigerant flowing from the heat exchanger for heat release to the decompression device to prevent generation of refrigerant overpressure. During the dehumidification and cooling operation, the gas refrigerant is liquefied by releasing heat in the heat exchanger for heat release...
