Abstract

The present invention provides a multi-split air conditioner for cooling and heating, comprising: at least one indoor unit for cooling and heating, each of which comprises an indoor heat exchanger; and a cooling and heating outdoor unit including a compressor, an outdoor heat exchanger, and a switching means disposed on the discharge side of the compressor to switch the flow of the refrigerant, the cooling and heating outdoor unit including a reservoir, the reservoir selectively stores refrigerant or oil according to a cooling operation mode or a heating operation mode and supplies the refrigerant or oil to the compressor. Therefore, in the liquid storage tank of the multi-split air conditioner for cooling and heating using the liquid storage device, the liquid storage device which is not used in the heating mode is converted to be used for storing oil, so that oil burning loss can be prevented under the condition that a structure is not increased.

Description

technical field [0001] The invention relates to a one-drag multi-air conditioner for cooling and heating, and in more detail, relates to a one-drag multi-air conditioner for cooling and heating that can solve the problem of compressor oil shortage during heating in cold regions. Background technique [0002] Usually, in a one-to-many air conditioner, a plurality of indoor units are connected to one outdoor unit, and the outdoor unit is shared, and the plurality of indoor units are respectively used as cooling devices or heating devices. [0003] In recent years, a plurality of outdoor units are connected and used in parallel to effectively cope with cooling or heating loads that vary according to the number of operating indoor units. [0004] The one-to-many air conditioner in the prior art includes a plurality of outdoor units, a plurality of indoor units, and refrigerant piping for connecting the plurality of outdoor units to the indoor units. Here, the plurality of outdoo...
