Problems solved by technology

In this case, increasing the opening degree of the outdoor expansion valve by executing the refrigerant accumulation elimination control causes the pressure (hydraulic pressure) of the refrigerant flowing through the liquid pipe to drop, resulting in a high pressure drop
Therefore, the temperature difference between the refrigerant temperature and the room temperature becomes small, and the heating capacity decreases.

Embodiment Construction

[0028] In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It may be evident, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown schematically in order to simplify the drawings.

[0029] Hereinafter, embodiments (examples) of the present invention will be described in detail based on the drawings. In the air conditioning apparatus of this embodiment, two outdoor units are connected in parallel with five indoor units. In the air-conditioning apparatus described above, the operation state of each indoor unit can be set (selected) to either cooling operation or heating operation, and the indoor units can be operated simultaneously (so-called cooling and heating free operation).

[0030] In addition, this invention is not limited to the following embod...

Abstract

The invention provides an outdoor unit of an air conditioning device and the air conditioning device. The outdoor unit of the air conditioner includes: an outdoor heat exchanger; a compressor; a refrigerant pipe connecting the outdoor heat exchanger and the compressor to an indoor unit having an indoor heat exchanger; Check whether the heating capacity of the operating indoor unit has decreased due to the retention of refrigerant in the indoor heat exchanger.

Description

[0001] Cross References to Related Applications [0002] This application is based on Japanese Patent Application No. 2012-168066 submitted to the Japan Patent Office on July 30, 2012, and therefore the entire content of said Japanese Patent Application is incorporated herein by reference. technical field [0003] The present invention relates to an outdoor unit of an air conditioner and an air conditioner. Background technique [0004] Conventionally, an air-conditioning apparatus including at least one outdoor unit and a plurality of indoor units is known, and the indoor unit is connected in parallel to the outdoor unit through a plurality of refrigerant pipes. Such an air conditioner is a so-called multi-point type (multi) air conditioner, for example, all the indoor units can simultaneously perform a cooling operation or a heating operation. Alternatively, this air conditioner can set (select) the operating state of each indoor unit to either cooling operation or heatin...
